  wtb系列低压无功功率补偿柜采用大功率无触点投切开关或电容投切专用接触器，根据电网电压电流及无功功率情况，由控制器实时进行动态分析、过零判断，实现快速无冲击地投入并联电容器组，以补偿电网无功功率，达到节能降损的目的。执行jb7113-1993《低压并联电容器装置》、gb7251-1997《低压成套并联设备》等标准。

 wtb series low voltagereactive power compensation ark adopts high power allowscontactless switching on-off switch or special contactor,capacitance can according to the power grid voltage and reactivepower current situation, by the controller in real time and dynamicanalysis, the zero judgment , no impact on the rapid into parallelcapacitor group,with power grid reative power compensation, achievethe goal of energy conservation and loss reducion.performjb7113-1993《low voltage parallel capacitor devices》、gb7251-1997《lowvoltage complete sets of e in parallel such as thestandard》

适用于0.4kv，50hz供配电系统进行功率因数补偿，也适用于异步电动机和变压器等感性负载进行就地功率因数补偿，达到功率因数自动调整，减少无功损耗，稳定电网电压，提高供电质量的目的。

scope of application. suitable for0.4kv,50hz power supply and diatribution sysytem for power factorcompensation, also applies to asynchronous motor and transformerand other perceptual load power factor compensation of the spot, toachieve automatic power factor adjustment, reduce loss of reactivepower and voltage stability of power grid. the purpose of improvingthe of power supply.
