Abstract

The invention discloses a misoperation prevention isolating switch which relates to an isolating switch, in particular to an isolating switch suitable for a soft starting cabinet of an electric motor. The invention can lock a handle when the handle is switched in a communication position so as to be capable of shutting down in time when an accident to be generated or the accident is generated in the running process of a large-scale electric motor. The invention is provided with cabinet door misoperation prevention systems playing a locking role in a soft starting cabinet door of the electric motor, the cabinet door is locked in the running process of the large-scale electric motor and can not be unlocked so as to prevent equipment damage or electric shock due to electric operation when high voltage is led in the soft starting cabinet of the electric motor. The invention reasonably limits the staring of the large-scale electric motor and the unlocking of the cabinet door by the two misoperation prevention systems with simple operation and ensures the safety of staffs 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 irreversible consequences.
