HXGN fixed high-voltage switchgear (referred to as ring network cabinet) is suitable for AC 50Hz, 10kV network as breaking load, short circuit and closing short circuit current.The ring network cabinet is equipped with manual and electric spring mechanism to operate the load switch, the grounding switch and the isolation switch are equipped with manual operation mechanism.
The ring network cabinet equipped with ZFN port-10/630 vacuum load switch should meet all the corresponding technical requirements of ZFN port-10/630 vacuum load switch.
Structure and working principle
The ring network cabinet uses air as the insulating medium and is mainly equipped with a ZFN port-10/630 vacuum load switch.
Inlet cabinet scheme
The main circuit in the cabinet has a ZFN port-10/630 vacuum load switch, which is equipped with an isolation knife and a grounding knife as appropriate. The three are installed on a rack and interlocked with each other.Therefore, the operation of connecting the busbar, isolation and grounding can be realized, and the cabinet can be flexibly equipped with CT, PT and other components.
Outlet cabinet scheme
The main circuit in the cabinet is composed of a ZFN port-10/630 vacuum load switch, a fuse with an impactor (with the function of an isolating switch) and a grounding knife, and it can also realize three-position operation.The cabinet can also be flexibly equipped with components such as CT/PT and ZNO arresters, so sometimes the metering cabinet can be omitted.
The incoming and outgoing cabinets are equipped with insulating and protective partitions that are interlocked with the grounding switch. The switches in the cabinet are mechanically interlocked with the partitions and cabinet doors, and meet the requirements of 'five defenses'. The enclosure level of the cabinet is IP2X.
