High-voltage electric cabinet with arc detection device

Abstract

The invention discloses a high-voltage electric cabinet with an arc detection device. The cabinet comprises a cabinet body, a mounting plate is arranged in the cabinet body; the mounting plate is usedfor mounting and fixing the electric appliance element; an electric arc detection device is arranged at the inner top of the cabinet body; the arc detection device comprises an arc light sensor and amoving assembly, the arc light sensor is arranged in the cabinet body through the moving assembly, the moving assembly can move the arc light sensor to the position in front of the mounting plate, meanwhile, the arc light sensor is further connected with a damping assembly, and the damping assembly can protect the arc light sensor moving rapidly. By arranging the movable arc light sensor, timelyand effective arc generation detection is guaranteed, safe power utilization, especially safety of large-scale industrial power utilization, is guaranteed, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the field of power distribution cabinet equipment, in particular to a composite high-voltage electric cabinet with an arc detection device. Background technique [0002] With the development of high-voltage power transformation technology, high-voltage transmission is distributed to various electrical appliances through the power distribution cabinet. Generally, various control circuit breakers are installed in the power distribution cabinet. During the opening and closing process of the circuit breaker, arc discharge will occur. The main hazard of arc discharge is that it may cause a fire. Once the direction of the arc is generated, its central temperature is as high as 3000 ° C, accompanied by molten metal, which is very easy to ignite the insulation layer of the internal line and cause the line to catch fire, especially if there are nearby When there are other combustibles, it is very easy to ignite the combustibles and caus...

[0002] With the development of high-voltage power transformation technology, high-voltage transmission is distributed to various electrical appliances through the power distribution cabinet. Generally, various control circuit breakers are installed in the power distribution cabinet. During the opening and closing process of the circuit breaker, arc discharge will occur. The main hazard of arc discharge is that it may cause a fire. Once the direction of the arc is generated, its central temperature is as high as 3000 ° C, accompanied by molten metal, which is very easy to ignite the insulation layer of the internal line and cause the line to catch fire, especially if there are nearby When there are other combustibles, it is very easy to ignite the combustibles and cause a fire, which affects the safety of power distribution. However, due to the installation position of the existing arc alarm device, the alarm is not timely, which easily leads to safety hazards

[0003] Therefore, the inventor of the patent of the present invention aims to invent a high-voltage electric cabinet with an arc detection device for the problem that the arc alarm is not timely and may easily cause safety hazards.
