直流漏电流传感器直流漏电流传感器是一种利用磁通门原理将被测直流电流转换成与该电流成比例输出的直流电流或电压信号的测量模块，原副边之间高度绝缘。

通常输出标准的直流DC4-20mA,DC0-5V,DC0-10V等信号，此标准信号可以被多种采集设备采集，如PLC,RTU,DAS卡等，用于多种电流监控的场合。

符合标准：霍尔电流传感器产品符合JB/T7490-2007《霍尔电流互感器行业标准》功能用途（应用场合））：功能用途（应用场合近年来国家对各行业的电气火灾的强制规定，使得直流供电系统得到了很大发展空间，直流供电系统广泛应用于各种发电厂，通信基站，消防领域中的断路器控制电源，应急电源等，在直流系统中直流漏电流传感器是不可或缺的一个重要元器件，对于设备的直流泄漏电流进行检测，广泛应用于直流输电、蓄电检测、直流屏、电源、大型医疗卫生设备、光伏、风力发电、通信基站等行业货设备中，第一时间对设备的漏电情况进行反馈，后端的漏电保护等原件会在第一时间采取相关措施，避免事故发生，安全使用、生产作业。

解析霍尔电流传感器当原边导线经过电流的输出信号是副边电流is，它与输入信号(原边电流ip)成正比，is一般很小，只有10~400ma。

如果输出电流经过测量电阻rm，则可以得到一个与原边电流成正比的大小为几伏的电压输出信号。

2、传感器供电电压vava指电流传感器的供电电压，它必须在传感器所规定的范围内。

超过此范围，传感器不能正常工作或可靠性降低，另外，传感器的供电电压va又分为正极供电电压va+和负极供电电压va-。

要注意单相供电的传感器，其供电电压vamin 是双相供电电压vamin的2倍，所以其测量范围要相供高于双电的传感器。

3、测量范围ipmax测量范围指电流传感器可测量的最大电流值，测量范围一般高于标准额定值ipn。

三、电流传感器主要特性参数1、标准额定值ipn和额定输出电流isnipn指电流传感器所能测试的标准额定值，用有效值表示(a.r.m.s)，ipn的大小与传感器产品的型号有关。

isn指电流传感器额定输出电流，一般为10~400ma，当然根据某些型号具体可能会有所不同。

2、偏移电流iso偏移电流也叫残余电流或剩余电流，它主要是由霍尔元件或电子电路中运算放大器工作状态不稳造成的。

电流传感器在生产时，在25℃，ip=0时的情况下，偏移电流已调至最小，但传感器在离开生产线时，都会产生一定大小的偏移电流。

产品技术文档中提到的精度已考虑了偏移电流增加的影响。

3、线性度线性度决定了传感器输出信号(副边电流is)与输入信号(原边电流ip)在测量范围内成正比的程度，南京中旭电子科技有限公司的电流传感器线性度要优于0.5%。

4、温度漂移偏移电流iso是在25℃时计算出来的，当霍尔电极周边环境温度变化时，iso会产生变化。

因此，考虑偏移电流iso的最大变化是很重要的，其中，iot是指电流传感器性能表中的温度漂移值。

5、过载电流传感器的过载能力是指发生电流过载时，在测量范围之外，原边电流仍会增加，而且过载电流的持续时间可能很短，而过载值有可能超过传感器的允许值，过载电流值传感器一般测量不出来，但不会对传感器造成损坏。

These two currents create magnetic fields that are also equal but opposite. When the wires are next to each other, the fields cancel,producing a “Zero Sum Current”. If any current leaks to ground from one wire (Ground Fault), the two currentsbecome imbalanced and the result is a net magnetic flux or field. AG Series ground fault sensors monitor this field and alarm when leakage rises above setpoint.

This warranty does not coverdamages caused by the user.∇∇∇Section 2. Operation2.1. OverviewThe H-10 Pro sensor uses positive ion emission technology, commonly known as a heated diode. It is very sensitive to only halon substances (refrigerants) making this product highly resistive to false alarming, while retaining superior sensitivity for pinpointing the most difficult to find refrigerant leaks.A pump inside the unit draws air through the probe to the sensor. The presence of refrigerant(s) causes the H-10 Pro to sound a speaker and illuminate an LED in the probe. Sensitivity to pinpoint small, medium, and large leaks can be controlled by setting the Leak Size switch (see Section 2.2).2.2. Panel Controls2.3. Before First Use…Before you use the unit the first time: 1.Remove the sticky-label disc from thecap of the calibration reference bottle.This disc can be reused to help seal the vial when the leak detector is not in use, or it can be discarded. DO NOT attempt to unscrew the cap, you may damage the bottle. The calibration reference bottle should last approximately six months.2.With the Power switch in the OFFposition, charge the battery using the wall adapter. Charge time is 3-4 hours or until the Full Charge LED turns green.2.4. Adjusting the SensitivitySet the Leak Size switch as follows.SMALL switch position is the highest sensitivity. The unit will indicate leak rates of 0.006 oz/yr or greater and is used for fluorine-based (HFC) gases like R134a. This position also assures highest repeatability for locating 0.1 oz/yr (or greater) leaks per SAE J2791 moving probe test conditions. It must always be used to verify performance and calibration when using the calibration reference bottle.When using the small leak range position, a leak of HFC causing an audible signal equal to that produced by the leak vialhas a leak rate of approximately 0.5 oz/year.MEDIUM switch position is used for chlorine-based (CFC and HCFC) gases like R12 and R22. The medium setting will indicate approximately a 0.1 oz/yr (or greater) leak rate. This position supports finding leaks of approximately 0.5 oz/yr (per SAE J2791) or greater. It is also useful for locating larger HFC leaks.When using the medium leak range position on a CFC or HCFC system, this leak rate would also be approximately 0.5 oz/year.LARGE switch position is used to zero in on large leaks of any refrigerant. The large leak setting should be used in conjunction with manual mode.2.5. Auto Mode vs. Manual ModeAuto mode enables the H-10 Pro to block out background levels of refrigerants. This greatly reduces and/or eliminates false alarms while retaining sensitivity to quickly locate small or medium size leaks. Pinpointing leaks in this mode requires continuous probe movement.If the probe is held stationary over a leak, the unit will zero out the leak, going into the idle 1 tick/second condition. Briefly moving the probe away from the leak (1-2 seconds) permits the unit to re-establish sensitivity. Returning to the leak site, the unit will alarm again. Continuing thisprocedure will reliably and repeatedly pinpoint the leak with each pass over the leak site.If a large leak is present, the auto zero circuit may reduce sensitivity to an unacceptable level to find small and medium sized leaks. If this condition exists, use the manual mode to pinpoint a large leak. The manual mode is also an effective means to determine if a large leak of any refrigerant exists prior to searching for leaks (see Section 2.4).In Manual Mode the auto-zero circuit is disabled. The unit will not zero the leak if the probe is held over the leak site. This mode may require frequent readjustment of the Manual Balance control to maintain the required 1 tick per second that indicates proper adjustment and calibration for all three sensitivity switch positions. Manual mode provides greater sensitivity than auto mode.2.6. Setup1.Turn the unit on.2.Slide mode switch to AUTO position.3.Slide the sensitivity switch to theSMALL position.4.Check Low Battery LED. If it glows red,the battery needs charging, or youmay operate the unit using the supplied wall adapter.!NOTE: The sensor does not operate when the low battery LED is on.5.Check for sufficient airflow by pointingthe probe tip toward the floor, covering it with your finger, then releasing your finger. If proper flow exists, the red ball should noticeably rise up into the probe when you uncover the probe tip. Note that the actual height and final resting position of the red ball are not important. If the airflow ball does not rise:a.Tap the probe lightly to ensure theball is not sticking.b.Check the filter in the probe tip,per Section 4.1. If the flow is stillinsufficient, then the unit shouldbe sent for repair to the nearestAuthorized Service Center.6.Allow two minutes for the sensor towarm up, after which the flashing probe light and sound indicator will idle at approximately 1 click per second.7.Test operation by quickly touching theprobe tip to the top of the calibration reference bottle (make sure sticky label is removed). The unit should respond with a rapid flash rate and sound verifying correct operation and optimum sensitivity. If the unit does not respond correctly, see Section 3.1.2.7. Checking for Leaks! SAFETY WARNING: For your safety, DO NOT use this device to detect for leaks of refrigerants which are rated as combustible/flammable gases (e.g., ASHRAE A2- or A3-rated refrigerants). 1.Set the range switch to theappropriate range to ensuremaximum sensor life. If the leak sizeis unknown, start at the Large leaksetting. This protects the sensor if alarge amount of gas is present.!IMPORTANT:Exposing the sensorto large amounts of refrigerant orholding the probe over a leak for along period of time will significantlyshorten sensor life.2.Check for leaks in a logicalprogression through the entiresystem.3.If surfaces are dirty or wet, wipethem off with a clean, dry cloth toreduce filter clogging and extendsensor life. DO NOT allow the unit todraw in moisture. Use of the suppliedrubber probe tip helps preventmoisture from being drawn into theunit. Check for moisture beforeinserting the probe into areas to bechecked for leaks.4.If leaks have not been detected usingthe large leak setting: Try using themedium or small setting asappropriate.If leaks have been detected using thelarge leak setting: After locating andrepairing any leaks requiring the useof the LARGE switch setting, switchto the MEDIUM setting and verify thesystem is free of leaks. For HFCrefrigerants (such as R134a), verifythe system is leak free using theSMALL setting. For CFC and HCFCsystems (such as R12 and R22), theMEDIUM setting is typically sufficientto verify that the system is free ofleaks that require repairing.After a leak is located and repaired,clear the area with shop air, set theunit on the small leak sensitivity, anddouble check equipment for smallleaks.∇∇∇Section 3. Calibration andPerformance3.1. Heater AdjustmentsThe sensor heater circuit can be adjusted to control the sensitivity of the unit. A heat setting that is too high causes instability due to excessive sensitivity and shortens sensor life. A heat setting that is too low causes decreased sensitivity. The heater adjustment LEDs, heater adjustment, and calibration reference bottle is a unique system for setting the correct sensor heat (sensitivity) for optimum performance and long sensor life. To check the heater setting:1.Slide the mode switch to AUTO, slidethe leak switch to SMALL, turn ONthe unit and allow it to stabilize(approximately 2 minutes).2.When stabilized (at approximately 1click per second), briefly touch theprobe tip to the calibration referencebottle with the probe (ensure thesticky label disc is removed from thetop of the bottle.3.If adjusted properly, the red LOWLED will go out and the green OK LEDwill briefly glow. This indicates thesensor’s heat/sensitivity is adjustedfor optimum performance.If the red LOW LED remains on whenyou briefly touch the bottle, thesensor heat is set too low and theHeater Adjustment must be turnedslightly clockwise using a smallscrewdriver. Allow unit to stabilizeabout one minute and retest. Repeatthis procedure until the green OK LEDbriefly glows.If the red HIGH LED glows, the heat isset too high and the heateradjustment should be turned slightlycounterclockwise using a smallscrewdriver. Allow the unit tostabilize for about 1 minute and thenrepeat the test. Repeat thisprocedure until the proper green OKLED is indicated.!NOTE:After initial check for correct heater adjustment, disregard the calibration LEDs. Their indication is meaningless during subsequent leak testing activity.!NOTE:Check for proper heat adjustment on a daily basis. This assures the H-10 Pro is calibrated for the correct sensitivity for your daily test activity.!NOTE:Frequency of sensor heat adjustment is a function of how much exposure the sensor has to refrigerant. Adjustment may be required every couple of weeks for heavy duty service and once every few months for light duty service. !NOTE:Over the usable sensor life, when heater adjustment is fully clockwise and the green OK LED will not come on, it is time to replace the sensor. (See Section 4.3.)∇∇∇Section 4. Maintenance4.1. Replacing the FilterTo protect the pump from damage due to foreign particles and moisture, replace the filter as it becomes dirty. With moderate use (15 to 30 minutes a day), it is recommended that the filter be replaced once per month. In dirty environments or with heavy use, replace the filter more frequently. Always replace the filter when it is visibly dirty or wet. To replace the filter, follow the steps below.1.Remove the black rubber probe tip.2.Pick out the filter with a pin ortweezers. A fine screen will remain in the tip of the probe nozzle (behind where the filter sits).3.Insert the new filter in the probe tip.Make sure that the filter is firmly seated against the screen.4.Replace the rubber probe tip.4.2. Replacing the Airflow Indicator1.Remove the clear plastic section of theprobe tip by gently pulling and twisting.2.Turn the probe tip upside-down andtap on it to remove the old airflow indicator ball.3.Insert the new airflow indicator ballinto the tip.4.Reattach the probe tip to the probeassembly.4.3. Replacing the SensorThe sensor needs to be replaced when the H-10 Pro no longer responds to the calibration reference bottle, even with the heater adjustment turned fully clockwise (make sure the reference bottle contains some refrigerant).1.Turn the leak detector OFF.2.Turn the heater adjustment to itsfull counterclockwise position.3.Unplug the power cord and openthe sensor cover.4.Allow the sensor to cool beforetouching it.!WARNING: Sensor temperaturemay cause a burn if not allowed tocool.5.Unplug and discard the sensor.6.Insert a new sensor and close thesensor cover.7.Adjust the heater per Section 3.1.∇∇∇Section 5.

0-500A电流传感器应用霍尔闭环原理，可隔离测量DC，AC，脉冲电流!输入电流：50A/100A/200A/300A/400A/500A输出方式：±4V或±5V供电：±12…15V (±5%)精度：±0.5mm穿孔孔径：￠40mm1、直放式（开环）电流传感器（CS系列）当原边电流I P流过一根长导线时，在导线周围将产生一磁场，这一磁场的大小与流过导线的电流成正比，产生的磁场聚集在磁环内，通过磁环气隙中霍尔元件进行测量并放大输出，其输出电压V S精确的反映原边电流I P。

一般的额定输出标定为4V。

2、磁平衡式（闭环）电流传感器（CSM系列）磁平衡式电流传感器也称补偿式传感器，即原边电流Ip在聚磁环处所产生的磁场通过一个次级线圈电流所产生的磁场进行补偿，其补偿电流Is精确的反映原边电流Ip，从而使霍尔器件处于检测零磁通的工作状态。

具体工作过程为：当主回路有一电流通过时，在导线上产生的磁场被磁环聚集并感应到霍尔器件上，所产生的信号输出用于驱动功率管并使其导通，从而获得一个补偿电流Is。

这一电流再通过多匝绕组产生磁场，该磁场与被测电流产生的磁场正好相反，因而补偿了原来的磁场，使霍尔器件的输出逐渐减小。

当与Ip与匝数相乘所产生的磁场相等时，Is不再增加，这时的霍尔器件起到指示零磁通的作用，此时可以通过Is来测试Ip。

当Ip变化时，平衡受到破坏，霍尔器件有信号输出，即重复上述过程重新达到平衡。

被测电流的任何变化都会破坏这一平衡。

一旦磁场失去平衡，霍尔器件就有信号输出。

经功率放大后，立即就有相应的电流流过次级绕组以对失衡的磁场进行补偿。

从磁场失衡到再次平衡，所需的时间理论上不到1μs，这是一个动态平衡的过程。

因此，从宏观上看，次级的补偿电流安匝数在任何时间都与初级被测电流的安匝数相等。
