Structure Characteristics
The switchgear equipment has cable incoming and outgoing wire, cable line overhead line, bus tie, isolation, voltage transformer, arrester and so on a wiring scheme. The switchgear equipment with heat shrinkable insulation material and epoxy coated with insulating process, optimization of the electrode shape, the cabinet body structure is very compact. The main circuit adopts insulated bus, the adjacent cabinet bus casing separated, can effectively prevent the spread of the incident, and to her mistress line to the auxiliary supporting role. Cable room is equipped with a current transformer, grounding switch, the ample space conditions for a plurality of cable connection. In military vehicles, circuit breaker, grounding switch and after the cabinet door is provided with a part to prevent misoperation mechanical interlocking device, "five prevention "Function is complete, safe and reliable.
