Safety double-circuit-breaker-chamber medium-voltage cabinet

Abstract

The invention provides a safety double-circuit-breaker-chamber medium-voltage cabinet. The safety double-circuit-breaker-chamber medium-voltage cabinet comprises a medium-voltage cabinet body, and anupper circuit breaker chamber, a lower circuit breaker chamber, a bus chamber, an upper cable chamber and a lower cable chamber which are arranged in the medium-voltage cabinet body. The bus chamber is arranged in the middle of the medium-voltage cabinet body; partition plates are arranged above and below the bus chamber; a left stand column and a right stand column are respectively arranged at the left and right sides of the bus chamber, the upper ends and the lower ends of the left stand column and the right stand column are connected with a top plate and a bottom plate of the medium-voltagecabinet body respectively; the upper circuit breaker chamber and the lower circuit breaker chamber are arranged at the left side of the bus chamber and are separated by a partition plate arranged inthe middle; the upper cable chamber and the lower cable chamber are arranged at the right side of the bus chamber and are separated by a separator plate arranged in the middle; and each cabin is provided with an independent pressure relief structure. According to the technical scheme, the problems of safety, use occasions, later maintenance, production cost and the like in the prior art are solved, a brand-new series is formed, market replacement imported products are met, and the requirements for national standards, universalization and low cost are met.

Description

technical field [0001] The invention relates to the technical field of AC metal-enclosed switchgear, in particular to a medium-voltage cabinet with double circuit breaker chambers for safety. Background technique [0002] At present, similar power distribution equipment on the market mainly includes the following products: [0003] The domestic GG1A cabinet is remodeled, the double circuit breakers are fixedly placed, and the disconnecting switch is used for the breakpoint. However, this kind of product has a simple structure and does not have the "five prevention" functions. It only has a simple mechanism to prevent misoperation, which has poor safety. The circuit breaker is fixed and placed, and daily maintenance is inconvenient. The cabinet body is welded with angle steel, which has low production efficiency and poor aesthetics. It is now rarely used and is an obsolete product, and existing products are gradually being replaced. [0004] For Mitsubishi, Fuji and other J...

AI Technical Summary

Problems solved by technology

However, the circuit breakers of this product are placed in double rows on the left and right, the cabinet body is wide, and the space requirements for the electrical room are high. Some occasions do not meet the conditions of use and are expensive.

[0006] In short, the existing products have problems such as poor safety, non-compliance with national standards, high cost, high maintenance and manufacturing costs, and cannot meet the use requirements.
