KGAS-500 DC Circuit Breaker

产品介绍
现在, the domestic DC circuit breaker ampere-second characteristics testing institutions and manufacturers for DC circuit breaker ampere-second characteristics testing equipment are fixed equipment, such as fixed high-current power supply, large load resistance, large volume, large weight, not easy to move detection, analysis instruments are conventional instruments such as voltmeter, ammeter, oscilloscope, ETC。, complex wiring, inconvenient use, It is not suitable for mobile detection of substations. In order to solve the problem of on-site testing of actual characteristics of DC circuit breakers, the company has introduced a kind of KDAS-500 ampere-second characteristics tester suitable for on-site use in substations, which is easy to carry and has a high degree of automation, which can provide the operation and maintenance department with a means of testing the action characteristics of DC protection appliances. In order to improve the reliability of DC system operation and ensure the safe and reliable operation of power grid, the action characteristics and level difference coordination of DC protection electrical appliances are checked.
KGAS-500 DC circuit breaker ampere-second characteristic tester is specially designed for substation test, overhaul and maintenance. It can meet the overload and short circuit characteristic test of DC circuit breaker, so as to improve the health level of substation DC system, and avoid the crossover trip and large-scale power failure caused by DC distribution network.
