A new panel device on the ring network cabinet

Abstract

The invention relates to a novel panel device on a ring main unit. The novel panel device comprises an electric mechanism operating device and a manual mechanism operating device, and the electric mechanism operating device comprises button devices and electric mechanism operating holes; the button devices comprise telescopic rods, positioning parts and locking parts, the telescopic rods are mounted in through holes in the positioning parts, the positioning parts are fixed to the locking parts, and the button devices are fixed to the electric mechanism operating holes through cooperation of the positioning parts and the locking parts; the manual mechanism operating device comprises a sliding assembly, a movable groove and sliding positioning grooves, the sliding assembly comprises a sliding piece and a chain ring, the chain ring is fixed on the sliding piece, and the sliding assembly is mounted in the corresponding sliding positioning groove through the sliding piece and moves up and down. The novel panel device is used for improving the IP protection grade of a panel and accords with requirements of bid inviting of the state grid corporation of China to the panel protection IP grade.

Description

technical field [0001] The invention belongs to the technical field of ring network cabinets, and in particular relates to a novel panel device on a ring network cabinet. Background technique [0002] The ring network cabinet is a kind of electrical equipment that installs high-voltage switchgear in a metal enclosure or manufactures it into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size, low price, and High power supply quality and performance as well as power supply security and other advantages. It is widely used in distribution stations and box-type substations of power supply centers such as cities and residential quarters, high-rise buildings, large public buildings, factories and enterprises, and scattered power consumption functions. [0003] The ring network cabinet currently used has three basic cabinet types: load switch, combined electrical appliance, and circuit breaker. The m...

AI Technical Summary

Problems solved by technology

[0003] The ring network cabinet currently used has three basic cabinet types: load switch, combined electrical appliance, and circuit breaker. The mechanism can realize manual and electric operation. Due to the existence of manual and electric operation holes, the IP protection level of the operation panel cannot reach the state grid bidding technical requirements such as figure 1 , 2 As shown, the opening and closing through hole 15 of the mechanism electric operation, the manual operation hole 16 of the mechanism and the interlocking hole 17 of the mechanism are all exposed, and the protection level cannot reach IP43
