Novel 10 kv environment-friendly gas all-insulated switch cabinet

Abstract

The invention discloses a novel 10 kv environment-friendly gas all-insulated switch cabinet. The switch cabinet is characterized by comprising cabinet bodies, a control assembly, a main bus assembly fixedly installed at the top of the inner cavity of each cabinet body, a first cable chamber, a second cable chamber and a circuit breaker chamber connected with the main bus assemblies. The circuit breaker assembly and the main bus assembly conduct circuit on-off operation in the circuit breaker chamber. The switch cabinet further comprises: an operating mechanism chamber provided with an on-off main circuit mechanism; a dust removal assembly; a fan arranged on the inner wall of each side in the cabinet body; a one-way air extractor connected with the inside and the outside of the cabinet body; and a sensor arranged in the cabinet body and right facing the inner wall of the cabinet body. By arranging double cabinet bodies, the problem of open circuit of fault maintenance of a single cabinet body is solved; by arranging the automatic dust removal assembly, dust is intelligently and automatically removed; by arranging multiple arc extinguishing structures and double cabinet doors, wrong operation and illegal operation of informal operators are avoided; and the switch cabinet is powerful in function and obviously enhanced in safety compared with an existing switch cabinet.

Description

Technical field [0001] The present invention relates to the field of switchgear, and more specifically, it involves a new 10kV environmentally friendly gas insulated switchgear. Background technique [0002] Currently, traditional switchgears generally use SF6 (hexafluoride sulfur) gas or solid insulation vacuum arc. However, SF6 is also a greenhouse gas. From the environmental protection angle, it should be used as little as possible or without SF6 gas. The solid insulation switchgear is extremely high, and its production cost is high. Second, the sealing switchgear is formed, and there are many problems. Among them, the problem is the most obvious, the cleaning problem in the cabinet, the existing 10KV switchgear must stop the use of the 10kV switchgear, affecting normal Production, while opening and 10KV switch cabinet will affect the service life of its circuit breaker due to cleaning, reduce the safety of the switchgear, and cleanly cleaning in the cabinet will likely affect...

AI Technical Summary

Problems solved by technology

However, SF6 is also a greenhouse gas. From the perspective of environmental protection, SF6 gas should be used as little as possible or not. The solid insulated switchgear has extremely high requirements on the manufacturing process, and its production cost is relatively high.

Secondly, forming a sealed switchgear during work also has many problems. Among them, the most obvious problem is the cleaning problem in the cabinet. When the existing 10kv switchgear is cleaned, the use of the 10kv switchgear must be stopped, which affects the normal operation. At the same time, opening and closing the 10kv switchgear due to cleaning work will affect the service life of its circuit breaker and reduce the safety of the switchgear. In addition, if the cabinet is not cleaned in time, it may affect the insulation of the switchgear and endanger the safety of people or equipment.
