Problems solved by technology
In this way, there will be a situation, that is, when the grounding switch of the composite switch is not in the closed state, there will be a safety hazard if the cable room door is opened directly, and there may be a risk of electric shock
[0004] On the other hand, the rear compound switch is also installed in the cabinet, and the position of the cable compartment door is usually located outside the conforming switch. Operation, of course, the compound switch can also be operated directly after the cable room door is disassembled. Obviously, this operation method has great potential safety hazards and is a wrong operation method

The invention discloses a high-safety looped network power distribution switch cabinet which comprises a cabinet body, a vacuum circuit breaker and a combination switch assembly are installed in the cabinet body, the combination switch assembly comprises a shell, an isolation switch and a grounding switch, two operation parts are arranged on the combination switch assembly, and two corresponding operation holes are formed in the shell; and the front side of the cabinet body is provided with a door plate, the door plate is provided with a window, and only after the door plate is installed, the operating rod can pass through the window and the operating hole to enter the operating part for switching-on and switching-off operation. In addition, in the structure, only when the grounding switch is in a closed state and the cabinet body is not electrified, the door plate can be opened, so that the personal safety is ensured. The high-safety looped network power distribution switch cabinet disclosed by the invention is convenient to operate and high in safety performance.
Description
technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a high-safety ring network power distribution switchgear. Background technique [0002] Ring Main Unit (Ring Main Unit) is a group of transmission and distribution electrical equipment (high-voltage switchgear) installed in a metal or non-metallic insulated cabinet or made into an assembled interval ring network power supply unit. Its core part adopts load switches and The fuse has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises. [0003] There is usually a cable compartment door on the front side of the ring network cabinet, which is mainly used for cable installation or maintenance. In the r...
