Ventilation device of buried prefabricated substation

Abstract

The invention discloses a ventilation device of a buried prefabricated substation and belongs to the transformer substation field. The device comprises a control box, a voltage transformation box is fixedly mounted at the bottom of the control box; a partition plate is fixedly connected to the interior of the control box; a fan is arranged on the right side of the top of the inner side of the voltage transformation box, the top of the fan is fixedly installed at the bottom of the control box, a screen cover is fixedly installed on the right side of the control box, a fixing shaft is fixedly connected to the inner side of the screen cover, and the left side of the fixing shaft is sleeved with a limiting lantern ring rotationally connected with the fixing shaft. According to the invention, astraight gear on an output shaft of the motor is engaged with a gear ring; the motor drives the supporting rod, the limiting lantern ring and a cleaning brush to rotate, the cleaning brush can cleana filter screen, it is guaranteed that the filter screen is not blocked, the transformer substation and the outside are kept ventilated well, in the sun, a shutter is controlled to enable humid air inthe transformer substation to be dried, dust falls into the sliding box, and workers can clean the substation conveniently.

Description

technical field [0001] The invention relates to the field of substations, in particular to a ventilation device for buried prefabricated substations. Background technique [0002] The prefabricated substation is electrically connected through cables or busbars. All high and low voltage power distribution devices and transformers are conventional stereotyped products. The prefabricated substation has the advantages of small size, small footprint, light weight, low cost, and reliability. "Box-type substation" or "prefabricated substation", and buried substation is buried in the soil, there are two kinds of half-buried and fully buried, which can be highly coordinated with the environment, and is a green, healthy and environmentally friendly product . [0003] In order to ensure the normal operation of components such as the transformer inside the substation, the heat emitted by the internal components must be dissipated. Keeping the substation and the outside ventilated can p...
