一、产品概述市场中的节电装置大都不具备稳压的功能,仅仅降低装置的供电电压,从而达到节电的目的。
其弊端为:当电网电压稍有波动时,装置的输出电压升高,不再节电;或者输出电压降得更低,对负载的影响较大。
由此可见,稳压功能是节电装置必备的一项功能,也是能够实现节电的必要条件。
LH-100型智能节电装置根据用户电网电压的波动情况、照明负载的性质,为负载提供稳定的供电电压。
用户可根据需求,设置输出电压,对负载的运行时间和供电方式进行编程,最大限度地降低负载的电耗。
二、结构它是由三相补偿变压器、三相调压变压器、传动机构、电刷接触系统、箱体和控制系统等组成。
三相调压变压器圆筒式绕组外表面经磨光加工,去除绝缘,呈光滑的导体面,以便于电刷良好接触;传动机构由电动机和蜗轮、蜗杆、链轮、链条组成;电刷系统结构合理可靠,以保证电刷压力;箱体采用封闭柜式,体积小,散热好,检测仪表位置醒目,提示准确。
三、工作原理LH-100系列节电装置由三相补偿变压器TB、三相调压变压器TUV电压检测单元、电动机控制与传动机构,接触操作电路等组成,其电气原理图一所示。
图一自动补偿电力稳压器电气原理图调压变压器TUV的一次绕组接成Y形,连接在稳压器的输出端,二次绕组连接补偿变压器TB的一次绕组,而补偿变压器工作原理,如图二所示。
若不计补偿变压器阻抗压降,则从图二可见:Uao=Uai+Uac式中:Uai—稳压器A相输入电压;Uao—稳压器A相输出电压;Uac—稳压器A相补偿电压;图二单相补偿电力原理图其原理是:当A相输入电压Uai增加ΔUai时,补偿电压Uac也相应改变ΔUac且ΔUac=-ΔUai时,使A相输出电压Uao保持不变,同理B相、C相也是如此。
其稳压调压过程是:根据输出电压的变化,由电压检测单元采样,检测并输出信号控制电动机SM转动,经减速机构并有链条带动调压变压器TUV上的电刷组滑动(或滚动)来调节调压器的第二次电压,以改变补偿电压的极性和大小,降低或升高输出电压,进而达到节电的目的。

QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 995AADJUSTABLE LDO LINEAR REGULATORLT3080EDD DESCRIPTIONDemonstration circuit 995A is an adjustable 1.1A lin-ear regulator featuring LT®3080. Architected as a precision current source and voltage follower, it al-lows this new regulator to be used in many applica-tions requiring high current, adjustability to zero out-put, and no heat sink. Also the device brings out the collector of the pass transistor to allow low dropout operation when used with multiple supplies.A key feature of the LT3080 is the capability to sup-ply a wide output voltage range. By using a reference current through a single resistor, the output voltage can be programmed to any level between zero and 36V. The DC995A has a reduced input voltage 25V due to input capacitor voltage rating. And DC995A is capable of delivering up to 1.1A output current. Therefore, the DC995A can be used as a high current linear regulator, post regulator for switching supply, variable voltage supply or low output voltage power supply. Internal protection circuitry includes current limiting and thermal limiting.LT3080 regulator is offered in 8-lead MSOP (with an Exposed Pad for better thermal characteristics), a 3mm × 3mm DFN, 5-lead TO-220 and a simple-to-use 3-lead SOT-223 version.The LT3080 datasheet gives a complete description of the part, operation and application information. The datasheet should be read in conjunction with this quick start guide for working on or modifying the demo circuit 995A.If more output current is required or heat-spreading is needed, LT3080 can be easily paralleled. See DC1294A for details.Design files for this circuit board are available.

Refer to Figure 1. for proper measurement equipment setup and following the procedures below: 1.Before proceeding to test, use VOUT Select jumper JP1 for the desired output voltage (1.8V or 0V-5V). If the output voltage is dif-ferent from the above values, use the USER option and install R3. Select R3 according to the following equation: AV R OUT µ103=.2.Assume 1.8V is the desired output. Apply 2.3V across Vin (to Gnd), and 3.4V acrossVcontrol. Draw 1.1A of load current. The measured Vout should be 1.8V ± 3% (1.766V to 1.875V). 3.Vary Vin from 2.3V to 25V, Vcontrol from 3.4V to 25V and the load current from 1mA to 1.1A. Vout should measure 1.8V ± 3% (1.766V to 1.875V).Note: Make sure the power dissipation is limited be-low the thermal limit.Figure 1. Proper Measurement Equipment SetupFigure 2. Measuring Input or Output RippleINPUT VOLTAGE RANGEThe guaranteed Vin dropout voltage is 0.5V at 1.1A, the guaranteed Vcontrol dropout voltage is 1.6V at 1.1A. The maximum Vin and maximum Vcontrol is reduced to 25V due to the input capacitor voltage rat-ing.DUAL SUPPLY OR SINGLE SUPPLYUse two separate supplies for Vin and Vcontrol, a low dropout voltage can be achieved on the Vin pin and the power dissipation is minimized. Alternatively, Tying the Vcontrol to Vin through a zero ohm jump resistor on board, a single supply is sufficient to drive the demo circuit 995A. AVOID USING A LONG WIRE TO TIE VCONTROL AND VIN.OUTPUT CURRENTThe output current will decrease at high input-to-output differential. The actual current output is further limited by the thermal shutdown function, which is related to the board thermal dissipation. A typical curve is provided using the demo circuit 995A at room temperature. DO NOT CONTINUOUSLY OPERATE THE LT3080 TO THE THERMAL LIMIT, WHICH MAY IMPAIR THE DEVICE RELIABILITY. MAXIMUM JUNCTION TEMPERATURE IS 125o C.oteknixTHERMAL IMAGEAn example thermal image shows the temperature distribution on board. The test is done in still air at room tempera-ture with 2.2W power dissipation in LT3080.BYPASS CAPACITORSince the SET pin is a high impedance node, unwantedsignals may couple into the SET pin and cause erratic behavior. This will be most noticeable when operating with minimum output capacitors at full load current. The easiest way to remedy this is to bypass the SET pin with a small amount of capacitance from SET to ground, 10pF to 20pF is sufficient. A 0.01uF bypass capacitor is used on the demo board to provide a low-noise output. Please refer to datasheet for details.。
