Cómo funcionaEl sistema de bombeo solar sirve para proporcionar agua en aplicaciones remotas donde la energía de la red eléctrica no es confiable o no está disponible. El controlador de la bomba solar BLDC puede utilizar directamente la energía de DC del conjunto de elementos fotovoltaicos y controlar las bombas de DC sin escobillas. En días soleados, el sistema de bombeo puede bombear agua continuamente. No hay necesidad de baterías u otros dispositivos de almacenamiento de energía. Se recomienda bombear agua a un depósito para su almacenamiento.Se puede instalar un interruptor de flotador en la torre de agua para controlar el funcionamiento de la bomba. E instale una sonda de bajo nivel en el pozo para detectar el agua del pozo y que la bomba se detenga cuando no haya agua. La Figura 1 muestra un diagrama típico del sistema de bombeo solar, que incluye partes y componentes principales.Consiste en:Matriz PVControlador de bomba de energía solarBomba sumergible de energía solarInterruptores de nivel de fuente de aguaInterruptores de nivel de tanque2. 4SSH3.0/80 – D48/650 Descripción de la bomba 2.1 Material de las piezas2.2 Especificaciones de la bomba2.3 Rendimiento de la bomba3. JL-197K1500-48 Información general del controlador3.1 CaracterísticasEl controlador de bomba solar JL-197K1500-48 está diseñado con el alto estándar de confiabilidad que se espera de los productos. El controlador intenta impulsar la bomba y el motor para suministrar agua incluso en condiciones adversas, reduciendo la salida según sea necesario para proteger los componentes del sistema de daños y solo apagándose en casos extremos. La operación completa se restaura automáticamente cada vez que disminuyen las condiciones anormales.InspecciónAntes de comenzar, inspeccione la unidad controladora de la bomba solar JL-197K1500-48. Verifique que el número de pieza esté conectado y que no haya ocurrido ningún daño durante el tránsito.NOTA: El controlador de bomba solar JL-197K1500-48 es el componente del sistema de bombeo solar que tiene otros dos componentes, la matriz PV y la bomba de DC sin escobillas.Características de protecciónLa monitorización electrónica le da al controlador la capacidad de monitorear el sistema y apagarse automáticamente en caso de:Condiciones de pozo seco - con interruptor de bajo nivelBomba enlazada - con par de inversión automáticaSobretensión de alto voltajeBajo voltaje de entradaCircuito de moto abiertoCortocircuitoSobrecalentamientoNOTA: Este controlador proporciona protección contra sobrecarga del motor al evitar que la corriente del motor exceda la corriente nominal y al limitar el ciclo de trabajo en caso de bajo nivel de agua. Este controlador no proporciona detección de temperatura excesiva del motor.Diagnósticos del sistemaEl controlador de bomba solar JL-197K1500-48 monitorea continuamente el rendimiento del sistema y detecta una variedad de condiciones anormales. En muchos casos, el controlador compensará según sea necesario para mantener la operación continua del sistema; Sin embargo, si existe un alto riesgo de daños en el equipo, el controlador protegerá el sistema de la condición de falla. Si es posible, el controlador intentará reiniciarse cuando la condición de falla disminuya.Arranque suave del motorNormalmente, cuando hay una demanda de agua y energía disponible, el controlador de bomba solar JL-197K1500-48 estará en funcionamiento. Cada vez que el controlador de la bomba solar JL-197K1500-48 detecta una necesidad de agua, el controlador siempre "aumenta" la velocidad del motor mientras aumenta gradualmente el voltaje del motor, lo que resulta en un motor más frío y una corriente de arranque más baja en comparación con los sistemas de agua convencionales. Esto no dañará el motor debido a la función de arranque suave del controlador.Exceso de temperaturaEl controlador de bomba solar JL-197K1500-48 está diseñado para funcionar a plena potencia desde una matriz solar en temperaturas ambiente de hasta 45 C. En condiciones de temperatura superiores a 45 ° C, el controlador reducirá la potencia de salida en un intento de evitar apagar. La salida completa de la bomba se restablece cuando la temperatura del controlador se enfría a un nivel seguro. Interruptor de control de nivelEl controlador de bomba solar JL-197K1500-48 puede acceder a dos interruptores de nivel de agua (sensor de nivel de pozo y un sensor de nivel) para detectar de forma remota y controlar la bomba automáticamente. El interruptor de nivel para el controlador de bomba JL-197K1500-48 es opcional, no obligatorio.EmpujeControl de velocidad Presione para correr detenerDescripción ligera y causa3.4 Forma de conexiónvoltajeVelocidadEncender / Apagar3.4.1 Diagrama total de terminalesu v w Conectar con la bomba U V W cablesPV + PV – Conectar con panel fotovoltaico PV + PV-WL & COM Conectar con sensor de nivel de agua de pozoTL & TH & COM Conectar con sensor de palanca de agua del tanque3.4.2 Operación del sensor de nivel de panque3.4.3Operación del interruptor de presión3.4.4La operación del nivel de pozo4.Panel solar configurar y forma de conexión 4.1configurado por un panel solar de 18 Vmp (VOC 22V)4.2Configurado por 30Vmp (Voc 37V) Panel solar4.3 configurado por 36Vmp (Voc44V) Panel solar5.Instalación mecánica y eléctrica5.1 Esquema y diagrama de dimensiones de instalación5.2 Instalación mecánica5.2.1 Protección contra sobrecalentamientoSi está en el exterior, el controlador debe instalarse en un lugar bien ventilado y evitar la luz solardirecta y la lluvia. La mejor ubicación de instalación está debajo del conjunto solar, lo que puede evitarel sobrecalentamiento del equipo y la degradación del rendimiento. La temperatura extremadamente alta puede hacer que el controlador deje de protegerse.Sugeriremos utilizar una caja eléctrica con interruptor.5.2.2 Selección de ubicaciónEl controlador de la bomba solar de la serie JL-197K está diseñado para funcionar a temperaturasambiente máximas de hasta 60 ° C. Para evitar el sobrecalentamiento causado por la falla, serecomienda instalar el controlador en una posición oscura.El controlador de la bomba solar de la serie JL-197K debe instalarse en una caja de control que tenga unrecinto cerrado para evitar la luz solar directa, lluvia, polvo, humedad, animales, plantas, etc. La caja decontrol debe tener una placa de glándula inferior para instalar el cable de alambre o conducto. Paradecidir el tamaño de la caja de control, consulte la siguiente Figura 4.。

The controller can be used with either a wind turbine alone, or a solar array alone, or wind + solar combined charging one battery bank at the same time.Warning! The “nominal” voltage of your wind turbine and the solar array should match the battery bank voltage 48V. This controller is only suitable for:- 48V wind turbines (3-phase AC 50-65V output)- 48V solar arrays (maximum power voltage 64-80V, open circuit voltage 80-100V).The controller comes packaged with a separate dump load unit which is required for unloading and protecting the battery whenit is fully charged.Features●Intelligent and powerful technology ensures a high level ofproduct reliability●Simple structure with a modular design guarantees astable performance●PWM charging mode for optimal charge acceptance by thebattery bank● A range of protection functions (overcharging, overvoltage,reverse polarity, load short circuit, lightning, current limiting, automatic brake etc)●Inbuilt temperature sensor for temperature compensationof charging●Small current charging mode for a low battery (gentlecharging of a very low battery with only part of the available current)Optional FeaturesThe controller comes with an in-built RS485 communication port which can accept connection of various devices, such as a remote meter display, control panel, GPRS communication module etc. These devices are optional and need to be purchased / configured separately from the controller, using the appropriate RS485 to USB / RS485 to 232 converting cables.2. First use and operating procedures1) Use insulated copper or tinned copper cables of theappropriate cross-section (but in any case not smaller than6 mm2) to connect system components.2) Connect the dump load to the DUMP LOAD terminals ofthe controller.3) Connect the battery to the BATTERY terminals on thecontroller. Although the controller has reverse polarityprotection, make sure the positive and negative cablesare connected to the correct “+” and “-” terminals.4) Attach the wind turbine output cables to the WIND INPUTterminal on the unit. Please make sure the wind turbine blades are not rotating or are moving at a very slowspeed during this step of the installation.5) Finally, connect the solar panel(s)to the positive andnegative SOLAR INPUT terminals on the controller.Please keep the solar panel(s) covered during this process.Wiring diagram6) The controller comes with an On / Off switch on the frontpanel. This switch is designed for customers looking to disable battery charging and divert all energy to the dump load (e.g. when away from the system for a long period of time). When the controller is in normal operation of the battery charging, this switch should stay in the “On”position.Turning it into the “Off” position disables battery charging and activates the dump load.7) If you need to disconnect the wind turbine for a significantperiod of time, please note that for most wind turbines it is not recommended that the 3 wind turbine AC output wires remain open circuit. Typically the best method is to short all three wires and isolate them from other objects. Consult your wind turbine manufacturer or supplier for detailed guidance on this question before making a decision.3.

－４８Ｖ整流器配置与直流系统设置（二）简单地说，电力系统把50赫兹的电压波电流波，叫做基波，不是50Hz的电压、电流就是谐波。

电力中因为有非线性的负载，比如整流器，劣质节能灯等等，这样的设备工作时，就会产生谐波。

比如单相整流器，就把50Hz的基波，“整”成具有100Hz、150Hz、200Hz……等等成分的信号，就出现了谐波。

这种会产生谐波的设备，我们常常叫它“谐波源”谐波是电力系统中的一种能量污染，会导致设备故障、设备无动作、电机损耗增大、……等等，无数的危害。

但是非线性设备要消除谐波，需要很大的成本。

签于国家目前没有法律处罚，所以绝大多数设备生产厂家都听之任之，就像排放废水废气一样，国家不罚就不去治理。

通常电网的基波频率为50HZ和额定电流I，而在经过变频器和整流设备时，基波频率被切割产生畸变则产生3次、5次、7次谐波，谐波频率的计算公式：谐波频率=基波频率×谐波阶次、、、、而谐波电流的计算公式是：谐波电流=基波电流÷谐波阶次。

所以只要知道了是几次谐波和基波电流就能得到谐波电流。

供电系统中的谐波在供电系统中谐波电流的出现已经有许多年了。

过去，谐波电流是由电气化铁路和工业的直流调速传动装置所用的，由交流变换为直流电的水银整流器所产生的。

近年来，产生谐波的设备类型及数量均已剧增，并将继续增长。

所以，我们必须很慎重地考虑谐波和它的不良影响，以及如何将不良影响减少到最小。

1 谐波的产生在理想的干净供电系统中，电流和电压都是正弦波的。

在只含线性元件(电阻、电感及电容)的简单电路里，流过的电流与施加的电压成正比，流过的电流是正弦波。

在实际的供电系统中，由于有非线性负荷的存在，当电流流过与所加电压不呈线性关系的负荷时，就形成非正弦电流。

任何周期性波形均可分解为一个基频正弦波加上许多谐波频率的正弦波。

谐波频率是基频的整倍数，例如基频为50Hz，二次谐波为100Hz，三次谐波则为150Hz。
