Technical Matters in the Construction of Low-voltage Apparatus Short-circuit Make-break Testing System

低压电器短路通断试验系统建设中的技术问题

The approach is designed a group of temperature controlled switch circuit which control whether the parallel resistance is activated or not. Temperature signal is come from bridge voltage signal which is power supply by constant current source.

技术途径是设计一组温控开关电路来控制并联电阻器是否接入，温度信号来源于恒流源供电下的传感器桥压信号。

In this paper, a new concept of bridge type high temperature superconducting fault current limiter ( HTSFCL) with serial resistance is introduced, which is especially on the control system, and also the low-voltage short circuit experiments have been carried out.

本论文主要针对这种新型桥路型限流器的控制系统进行研究，并参与了380V/60A新型桥路型限流器的试验样机制作和短路故障限流实验。
