The Ampere-second characteristic tester specially produced by Shanghai Baixie Electric Technology Co., Ltd. is suitable for the ampere-second test of DC circuit breakers used in substations. It can verify the operating characteristics and differential coordination of DC protection devices to improve the operation of DC systems. Reliability, ensure the safe and reliable operation of the grid.
One hundred test card - circuit breakers and second-time performance tester features six advantages:
1. The main control part adopts high-performance industrial computer and windows operating system to display the waveform diagrams and values ​​of various parameters in real time;
2. Linear constant current control technology, new power device, high constant current, and independent setting of test current;
3, test methods: full-point test or sampling test;
4, can test the DC switch over-current and short-circuit fast break;
5, the device has self-protection function to ensure the safety and reliability of the test process;
6, the management software can be on the circuit breaker's ampere-second characteristic curve, data, inquiry, analysis and report form output and so on.
