Description

High-voltage soft-start cabinet provided with grounding knife

Technical Field

The utility model relates to the technical field of high-voltage soft start cabinets, in particular to a high-voltage soft start cabinet with a grounding knife.

Background

Because the internal electric elements of the traditional high-voltage soft-start cabinet are full without installation space and cannot be provided with the grounding knife, the grounding knife needs to be installed at another position, people need to find contact in advance during maintenance, and the time of the people is prolonged.

Therefore, it is necessary to provide a high voltage soft start cabinet with a grounding switch to solve the above technical problems.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a high-voltage soft start cabinet provided with a grounding knife, wherein the grounding knife can be arranged in the high-voltage soft start cabinet.

The utility model provides a high-voltage soft start cabinet with a grounding knife, which comprises a cabinet body, wherein first sensors are fixedly and symmetrically arranged inside the cabinet body, fuses are fixedly arranged at positions, close to the first sensors, of the cabinet body, a plurality of first sensors are electrically connected with the fuses, a soft start device is fixedly arranged at the bottom of the inner wall of the cabinet body, an isolating switch is arranged in the middle of the cabinet body, a main vacuum contactor is arranged in the middle of the cabinet body, and the grounding knife is arranged on one side of the inner wall of the cabinet body. When people maintain the equipment, after the circuit is disconnected, the grounding knife controls the closing action, and the equipment is overhauled in advance.

Preferably, the closing direction of the grounding knife is from bottom to top. The working movement range of the grounding knife is reduced, and the smooth operation of people is improved.

Preferably, a nameplate is installed at one side of the cabinet body. And marking the data of the cabinet.

Preferably, the circuit breaker is installed at a position, close to the nameplate, on the inner wall of the cabinet body. The control of the electric appliances in the cabinet body is realized.

Preferably, the cabinet body is provided with a simulation board at a position close to the circuit breaker. The circuit system of the cabinet body is provided.

Preferably, the bottom of the cabinet body is fixedly provided with a second sensor, and the second sensor is electrically connected with the soft starting device. And protecting the soft starting device.

Compared with the related art, the utility model has the following beneficial effects:

when the soft-start switch is used, when equipment needs to be overhauled in a power failure mode, the circuit breaker is used for conducting power-off operation on electric appliances in the cabinet body, the grounding knife switch is switched on, power transmission errors can be prevented, powerful guarantee is brought to safety of maintainers, meanwhile the 'five-prevention' requirement of the soft-start cabinet is improved, after no power is confirmed, namely when circuits and equipment are conducted, the grounding knife switch can be installed at the rear part in the cabinet body by changing the moving direction of the conventional grounding knife switch in the switching-on and switching-off process, and use convenience of people is improved.
