开关柜是指按一定的线路方案将一次设备、二次设备组装而成的成套配电装置,是用来对线路、设备实施控制、保护的,分固定式和手车式,而按进出线电压等级又可以分高压开关柜(固定式和手车式)和低压开关柜(固定式和抽屉式)。开关柜的结构大体类似,主要分为母线室、断路器室、二次控制室(仪表室)、馈线室,各室之间一般...
The modular panel design saves interior panel space, permitting the use of single-door access, in some cases. Panel doors cannot be opened with live electricity without some form of electronic authorization, and a record of access is stored for future reference. Power may not then be ...

(1)参数设置问题不当引起的,如时间设置过短; (2)外部因素引起的,如电机绕组短路,包括(相间短路,对地短路等); (3)变频器硬件故障,如霍尔传感器损坏,IGBT模块损坏等。 2. UVT故障 UVT为欠压故障,相信很多客户在使用中还是会碰到这样的问题,我们常见的欠压检测点都是直流母线侧的电压,经大阻值电阻分压后采样...
常规变电站的二次回路有两种:直流回路和交流回路。直流回路的功能:控制、保护逻辑、信号。交流回路的功能:保护、测量、计量。 到了智能变电站时代,一次设备与保护、测控之间的电缆被光缆取代,电缆中传输的直流信号(正电压/负电压/地电压)和交流信号(CT、PT二次电流、电压)被网络中传输的报文取代,过去用于实现保护逻...
