Indoor switch cabinet switch fault assistant emergency device

Abstract

The invention discloses an indoor switch cabinet switch fault assistant emergency device. The device comprises a positioning connection assembly, and an operation rod assembly and a visiting assemblywhich are installed on the positioning connection assembly. The positioning connection assembly is used for being fixed to the inner side of a switch cabinet door of a switch cabinet body. The operation rod assembly comprises a storage base and a telescopic ejector rod with one end connected into the storage base. The free end of the telescopic ejector rod is arranged opposite to a circuit breakeropening button, and the circuit breaker opening button is jacked and pressed through stretching and retracting of the telescopic ejector rod. The visiting assembly is used for visiting a mechanical opening display screen so as to acquire the working state of the circuit breaker opening button. The device is convenient for personnel to operate and carry, thereby achieving the purpose of quickly isolating fault equipment on site. The power utilization reliability is improved, and the personal injury risk hidden danger caused by on-site operation of operation and maintenance personnel is avoided. The high-quality service of power supply is improved. The reliability of stable operation of equipment is guaranteed, and the negative influence of power failure of one section of bus on distribution and stop of other equipment is avoided.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation equipment maintenance, in particular to an emergency device for an indoor switch cabinet switch failure assistant. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. [0003] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed ...

AI Technical Summary

Problems solved by technology

[0006] First, affected by equipment quality problems, the quality of some circuit breaker opening coils is not good enough and is easy to burn out, which may cause the circuit breaker to refuse to move;

[0007] The second is that the old stations that have been in operation for more than 10 years have different degrees of wear and tear on the mechanism, which causes the opening of the gate to be difficult and may easily cause the opening coil to burn out; the third is that the fixed shell of the opening coil of some manufacturers is made of plastic material, which is easy to crack after two or three years of operation. These problems, such as the refusal of the circuit breaker caused by the disconnection of the opening coil, have seriously affected the reliability of improving quality services and ensuring the stable operation of equipment
