10KV high-voltage switch cabinet with secondary cable chamber at top

Abstract

The invention discloses a 10KV high-voltage switch cabinet with a secondary cable chamber at the top. According to the 10KV high-voltage switch cabinet, a comprehensive cable chamber consisting of a rear sealing plate, a cover plate (2), a communication grounding bus, an insulator, a partition plate, a cover plate (1), a bus seat, a header plate and a bracket is arranged above a high-voltage switch cabinet instrument chamber; the rear sealing plate, the partition plate and the header plate are connected with an instrument chamber top cover through bolts, the upper portions of the rear sealingplate, the partition plate and the header plate are connected with the cover plate (1) and the cover plate (2), and the partition plate is positioned between the rear sealing plate and the header plate, so that two semi-closed compartments are formed among the rear sealing plate, the partition plate and the header plate; the compartment between the partition plate and the header plate is also usedas a control bus chamber; and the compartment between the rear sealing plate and the partition plate is used as a secondary cable chamber. According to the invention, the influence on the operation of other switch cabinets due to uncovering of the secondary cable trench cover is effectively avoided; and the space of the instrument chamber is enlarged, so that the maintenance of the instrument chamber is convenient.

Description

technical field [0001] The invention relates to a cabinet structure of a 10KV high-voltage switch cabinet, in particular to a cabinet structure of a 10KV high-voltage switch cabinet with a secondary cable room on the top of the cabinet. Background technique [0002] At present, in the cabinet structure of 10KV high-voltage switchgear, the control busbar room is generally located in the upper part of the instrument room of the cabinet body, and the internal control busbars generally adopt a single-layer or double-layer arrangement. single. [0003] The secondary cables of the high-voltage switchgear are usually laid in the cable trench on the front side of the high-voltage switchgear installation foundation, which is the cable channel for the control, detection, protection and signal circuits of the high-voltage switchgear. During daily inspection and maintenance, it is often necessary to remove the cover plate of the cable trench, which will affect the operation of the high...

AI Technical Summary

Problems solved by technology

During daily inspection and maintenance, it is often necessary to remove the cover plate of the cable trench, which will affect the operation of the high-voltage switchgear next to it, especially when the ground is covered with insulating rubber sheets, and the insulating rubber sheets and cables are opened in a large area Trench cover, which is extremely inconvenient for inspection and maintenance of secondary cables
