Inter-ring main unit two-in-one interlocking mechanism

Abstract

The invention belongs to the technical field of ring main unit interlocking, and discloses an inter-ring main unit two-in-one interlocking mechanism. The mechanism comprises a cabinet body, a closing switch and an opening switch are movably mounted on the front side wall face of the cabinet body, and a mounting plate is fixedly mounted at the position, corresponding to the closing switch and the opening switch, in the cabinet body; the closing switch and the opening switch penetrate through the front and rear side walls of the mounting plate, a lock hole is formed in the left side of the front side wall face of the cabinet body, and an auxiliary hole is formed in the position, corresponding to the lock hole, of the front side wall face of the cabinet body. According to the inter-ring main unit two-in-one interlocking mechanism of the invention, when an extrusion block is in contact with a transmission block, the transmission block is extruded by the extrusion block to move to the outer side; the position, corresponding to the transmission block, on the mounting plate is movably provided with a limiting strip through a placement block; and when the transmission block moves, the limiting strip is extruded, so that the limiting strip moves into a limiting hole formed in the closing switch, and at the moment, the closing switch is limited by the limiting strip, so that the situation that the closing switch is pressed down by mistake during working is avoided.

Description

Technical field [0001] The present invention relates to the field of ring cloveshan locking techniques, and more particularly to a two-in-one interlocking mechanism between a ring wrench cabinet. Background technique [0002] The ring network cabinet is an electrical device that collects high voltage switchgear in a metal closed, or is an electrical device of a splicing spacer network power supply unit, and its core component is a load switch and a fuse, which has simple structure. Small, low price, can improve the quality and performance of power supply and improve power supply safety, and the ring cabinet is widely used in the power supply center of urban and residential communities, high-rise buildings, large public buildings, factory enterprises and other power supply centers and box substations. In the case of the improvement of the use requirements, the structure of traditional ring cabinets can no longer meet some new security requirements, and there are many defects in st...

Problems solved by technology

[0002] The ring network cabinet is a kind of electrical equipment that integrates high-voltage switchgear in a metal-enclosed fixture, or makes a spliced ​​interval ring network power supply unit. Its core components are load switches and fuses. It has a simple structure and a small size. Small, low price, can improve the quality and performance of power supply and improve the safety of power supply, the ring main unit 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 Among them, with the improvement of use requirements, the structure of the traditional ring network cabinet can no longer meet the requirements of some new safety performance, and there are many defects in its structure

[0003] The ring network switchgear is one of the main equipment used for ring network power supply, and the safety of its operation process is particularly important; in the combined electrical structure of the ring network cabinet isolating switch and circuit breaker currently used, in order to "prevent live closing and opening Isolation switch" meets daily needs. In 10KV equipment, objects are generally used to block the operating hole of the circuit breaker and the operating hole of the isolating switch to realize the operation. This control method is not effective, the function is relatively simple, and it is easy to misoperate. When the circuit breaker is closed, the action of the isolating switch is stopped. Therefore, the existing ring network cabinet often has electrical misoperation accidents due to misoperation, and electric shock accidents during the maintenance process. The safety of the switchgear is low, and the safety guarantee of the maintenance personnel is low.
