Description

Technical Field

[0001] The utility model belongs to the technical field of electrical auxiliary equipment, and in particular relates to an auxiliary bracket for live maintenance of an instrument room of a KYN type switch cabinet. Background Art

[0002] KYN switchgear primarily consists of a fixed cabinet body and a trolley that slides and pulls with it, as well as a busbar compartment, circuit breaker compartment, cable compartment, and instrument compartment, separated by partitions. The instrument compartment is equipped with various instruments, switches, and terminal blocks, depending on the needs. Instruments are typically installed at the rear side of the compartment, while terminal blocks are typically located at the bottom. When performing live maintenance in the instrument compartment, an insulating blanket is typically placed over the terminal blocks to prevent accidental contact with live terminals. However, due to the confined space and numerous devices within the instrument compartment, maintenance personnel are prone to pressing their hands on the insulating blanket or colliding with tools during maintenance. This pressure or collision can cause a short circuit to the terminal blocks beneath the blanket, leading to equipment short-circuit failures. To address these issues, a tool is needed to protect the terminal blocks during live maintenance to improve safety. Utility Model Content
