便捷式可调电源

Convenient Adjustable Power Supply

随着电力系统地发展,对于供电可靠性的要求不断提高,变电站的安全运行就显得尤为重要,而断路器是变电站的主要设备,为了保障变电站的安全运行,需对断路器进行定期测试,而开关特性测试即是对开关最有效的测试手段。在目前的各种开关特性测试仪中,均需要提供220 V的交流电源,而部分开关特性测试仪还需要提供可变的直流电源。同时变电站中,如需使用220 V的交流电源,需找到测试设备场地区域的检修电源箱。但在变电站扩建时,经常出现检修电源箱未同步进行扩建,导致整个宽广的220 kV区域只有一个检修电源箱,使用时需要使用2~3个3 m的接线盘,对开关特效工作带来极大的不便。

With the development of power systems,the requirements for power supply reliability continue to increase,and the safe operation of substations is particularly important.Circuit breakers are the main equipment of substations.In order to ensure the safe operation of substations,circuit breakers need to be tested regularly,And the switch characteristic test is the most effective test method for the switch.In the current various switching characteristic testers,220 V AC power supply is required,and some switching characteristic testers also need to provide a variable DC power supply.At the same time,if you need to use 220 V AC power in the substation,you need to find the maintenance power box in the test equipment site area.However,it often happens that when the substation is expanded,the maintenance power box is not expanded synchronously,resulting in only one maintenance power box in the entire wide 220 kV area.When using it,you need to use 2~33 m wiring panels,which is extremely effective for switching special effects.Great inconvenience.
