智能型电压互感器仿真负荷箱

Intelligent Voltage Transformer Simulation of Load Box

在电压互感器误差校验中电压负荷箱是其中模拟被校电压互感器二次负荷必不可少的设备,传统电压负荷箱由于功率因数单一、量值不能连续可调的缺点很难满足电压互感器误差校验中的需要,因此研制开发功率因数和量值都能连续可调的智能型电压互感器仿真负荷箱成了一种重要趋势。本文主要介绍智能型电压互感器仿真负荷箱的原理线路、参数、应用和校验。

The voltage load box is essential equipment which analogs secondary load of transformer in the voltage transformer error checking.The traditional voltage load box cann＇t be to meet requirement of voltage transformer error checking because of shortcoming as power factor single value and value cann＇t continuously adjust.Therefore, it is one of important trends to research intelligent voltage transformer simulation of load box which value and power factor can be continuously adjust.The paper mainly introduces verification,application,parameter and principle circuit of intelligent voltage transformer simulation of load box.
