Problems solved by technology

[0007] 1. Only after the lock is locked can it prevent misoperation, so in order to prevent misoperation, it must be locked, and if it is not locked, misoperation cannot be prevented;
[0008] 2. The steps of locking are cumbersome;
[0009] 3. After being locked, it can only prevent the misoperation of the isolating switch, but cannot prevent the misoperation of the motor soft starter cabinet door

Abstract

The anti-misoperation isolating switch relates to an isolating switch, in particular to an isolating switch suitable for a motor soft starter cabinet. The invention prevents the handle from being locked when the handle is in the on position, so as to prevent the large motor from running and stopping in time when an accident is about to be caused or has already been caused. The invention has a cabinet door anti-misoperation operating system with the function of locking the cabinet door of the motor soft starter cabinet. During the operation of the large motor, the cabinet door is locked by it and cannot be opened to prevent high voltage from passing through the motor soft starter cabinet. When the power is on, the equipment will be damaged or electric shock will be caused. The present invention reasonably restricts the starting of large motors and the opening of cabinet doors through the above-mentioned two easy-to-operate error-proof operating systems, thereby ensuring the safety of staff and equipment.

Description

technical field [0001] The invention relates to an anti-misoperation operating system of an isolating switch, in particular to an anti-misoperation operating system of an isolating switch suitable for a motor soft starter cabinet. Background technique [0002] The motor soft starter cabinet is a key part to ensure the normal starting of large motors and control the operating conditions of the motors. [0003] Large motors are mainly used in some important occasions in factories and mining areas, such as the drive of large equipment in metallurgical plants, the drive of coal production equipment in coal mines, etc. The operation of these large motors is not only related to normal production, but also related to the safety of employees. [0004] Therefore, the motor soft starter cabinet plays an important role in the safety production links of these factories and mining areas. A misoperation of the motor soft starter cabinet may cause irreparable consequences. [0005] Ther...
