The solid insulated ring network cabinet is a set of high-voltage switchgear installed in a steel plate metal cabinet or made into an assembling interval-type ring network power supply unit. Its core part adopts load switches and fuses. It has a simple structure, small size and low price. , It can improve the power supply parameters and performance, as well as the advantages of power supply safety. It is widely used in distribution stations and box-type substations of load centers in urban residential districts, high-rise buildings, large public buildings, factories and enterprises.
The top unit group of the solid insulated ring network cabinet produced by our company is composed of isolation switches, called the busbar room. The front of the busbar room is the instrument room. The two rooms are separated by steel plates. The upper part of the cabinet is the load switch room. The middle and lower part is the room for cable entry and exit and other components. The main equipment of the solid insulated ring network cabinet is composed of a vacuum load switch, isolation switch, (or isolation switch with fuse), grounding switch, lightning arrester, operating mechanism, interlocking mechanism and measurement and metering circuits. It has the advantages of small size, light weight and convenient combination.
The solid cabinet switch body adopts a three-phase independent device method, and the three-phase units are respectively sealed in a new type of epoxy resin cast insulating body.
The main fracture of the switch adopts a vacuum interrupter and an optimized electromagnetic field structure. The main switch insulated pull rod moves up and down under the drive of the operating transmission mechanism to complete the closing and opening of the main switch.
Optimized electric field design. The insulating rod of the direct-acting switch-off switch moves up and down under the driving of the operating mechanism to complete the switch-on, switch-off and grounding of the switch-off switch.
The structure of the L module and the V module are completely different. The only difference is the performance of the vacuum interrupter for the main switch. It is easy to install; the F module is easy to change the fuse, and when the fuse is changed, the lower fuse seat is firmly grounded to ensure personal safety.
