Description

Overhead incoming line switch cabinet and cabinet body thereof
Technical Field
The invention relates to an overhead incoming line switch cabinet and a cabinet body thereof.
Background
In order to operate or maintain components in the switch cabinet conveniently, a front door is usually arranged on the switch cabinet, and because the switch cabinet is large in volume and an operator is difficult to operate the components at the rear part in the cabinet, a rear door is arranged on the rear wall of the switch cabinet, and a plurality of rear doors are usually arranged in the height direction of the cabinet body in order to operate the components at different heights in the cabinet body. The front door and the rear door of the cabinet body are closed to form a closed structure, so that great potential safety hazards exist, when electric arcs are generated due to faults in the cabinet, the temperature inside the switch cabinet rises, internal air pressure rises, air is sprayed out from the front side of the switch cabinet to cause accidents of operators, peripheral personnel and equipment, and in order to prevent the accidents, the switch cabinet is usually provided with a pressure relief device. Meanwhile, for the switch cabinet with the current being larger than or equal to 3150A, in the using process, the electric devices in each compartment generate more heat and need to be ventilated and radiated.
In the switch cabinet in the prior art, a pressure relief plate and a fan are generally arranged at the top of the cabinet body to realize pressure relief and ventilation and heat dissipation of the switch cabinet. Chinese utility model patent like grant publication No. CN202737346U, application date are 2012/06/11 discloses a cubical switchboard, including the cabinet body, the internal circuit breaker room that is equipped with of cabinet, the below of circuit breaker room is equipped with reserve room, and the cable chamber is located one side of reserve room and circuit breaker room, and the bus-bar room is located the top of cable chamber, all is equipped with the baffle so that each room forms relatively independent compartment between circuit breaker room, reserve room, cable chamber and the bus-bar room. The top of the cabinet body is sequentially provided with a circuit breaker chamber, a bus chamber and a cable chamber circuit breaker chamber pressure relief cover, a bus chamber pressure relief cover and a cable chamber pressure relief cover at intervals from front to back, and each pressure relief cover is provided with a pressure relief opening and a pressure relief plate covering the pressure relief opening.
When above-mentioned cubical switchboard took built on stilts inlet wire mode, also when the generating line was arranged to draw forth from the transformer and was walked the line by the overhead top entering cable chamber of cubical switchboard, if the generating line was arranged from the rear portion inlet wire at the top of the cabinet body, the cable chamber pressure release mouth that sets up at the rear side at cabinet body top was arranged by the generating line and is occupied, original pressure release mouth is used for the fixed high-voltage bushing of installation, and be equipped with the generating line bridge that provides enclosure space above the cabinet body top, because the isolation requirement that the generating line was arranged leads to the size of generating line bridge too big, can't avoid original cable chamber pressure release mouth at the top of the cabinet body and reset the pressure release mouth of cable chamber again, above-mentioned generating line is arranged, generating line bridge and high-voltage bushing form the inlet wire structure, also the inlet wire structure has occupied original setting at the communicating pressure release mouth of cable chamber at cabinet body top. Because the rated current of generating line row is great, if the cable chamber takes place to strike the arc trouble, the cable chamber that lacks the pressure release mouth has very big potential safety hazard, causes the accident easily to enlarge.
