Problems solved by technology

[0003] Most of the existing ring network cabinets use SF6 gas to realize sealing operation, but SF6 is one of the greenhouse gases, which is harmful to the environment and has the risk of leakage. At the same time, due to the need for good sealing performance, it is inconvenient to operate during maintenance and replacement. Therefore, we propose an atmospheric pressure closed ring network cabinet to solve the above-mentioned problems

Abstract

The invention relates to the technical field of ring main units, in particular to a normal-pressure closed ring main unit which comprises a box body, a fixing plate is fixedly connected to one side of the box body, a sealing box is fixedly connected to the inner wall of the top of the box body, a sliding plate slidably penetrates through the bottom of the sealing box, and a first limiting plate is fixedly connected to the bottom of the sliding plate. Two tension springs which are symmetrically arranged are fixedly connected between the top of the first limiting plate and the bottom of the sealing box, a mounting groove is formed in the sliding plate, and a control assembly used for adjusting the wiring state is arranged in the mounting groove. The internal part of the ring main unit can be sealed by utilizing air, the leakage risk is avoided, the sealing performance is good, the device does not need to be completely opened during maintenance and replacement, the sealing performance of the device can still be ensured, the working state can be easily controlled by utilizing the control assembly, and the use is convenient.

Description

technical field [0001] The present disclosure relates to the technical field of ring network cabinets, in particular to a normal-pressure closed ring network cabinet. Background technique [0002] Ring network cabinet (is a group of transmission and distribution electrical equipment (high-voltage switchgear) installed in metal or non-metal insulated cabinets or electrical equipment made into assembled interval ring network power supply units, the core part of which uses load switches and fuses, with It 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, etc. middle. [0003] Most of the existing ring network cabinets use SF6 gas to realize sealing operation, but SF6 is one of the greenhouse gases, whi...
