Abstract
The invention discloses an explosion-proof power distribution cabinet. The power distribution cabinet comprises a cabinet body, a cabinet door, three hand-operated direction valves, a nitrogen gas cylinder, a first level pressure reducing valve, a second level pressure reducing valve and the like. The cabinet door is installed on a front side of the cabinet body. And the cabinet door is provided with the three hand-operated direction valves and an observation window. An outlet of the nitrogen gas cylinder is connected to the first level pressure reducing valve. And then the first level pressure reducing valve is connected to a tee-junction air inlet. The three hand-operated direction valves correspond to three air cylinders respectively. Cylinder bodies of the three air cylinders are hinged to and installed on bottom portions of three slide rails respectively. Three switch plectrum plates are installed on the three slide rails in an up-down sliding mode respectively. Piston end portions of the three air cylinders are fixedly connected to the three switch plectrum plates respectively. Three load switches are installed in the cabinet body respectively. In the invention, through arranging a nitrogen protection device and a pneumatic switch, an explosion-proof function of the power distribution cabinet is realized; safety performance is good and operation is conveniently.
