A substation prefabricated cabin and its ventilation system

Abstract

The invention provides a transformer station prefabricated cabin and a ventilation system therefor, so as to solve a problem that a conventional ventilation system with a gravity shutter is not universal for air incoming and outgoing. The system comprises a blower fan and a gravity shutter structure, and the air incoming and outgoing ends of the blower fan are respectively provided with installation structures for installing the gravity shutter structure. During installation, the gravity shutter structure can be installed on different installation structures according to the actual needs, thereby enabling the ventilation system to be changed into an air incoming system or an air outgoing system. The installation process is convenient, and the ventilation system can achieve the switching of two modes: air incoming and air outgoing, and solves a problem that a conventional blower fan is not universal during installation. Moreover, the installation holes on the two installation structures can be designed and processed in a modularized manner, and the processing process is convenient.

Description

technical field

[0001] The invention relates to a substation prefabricated cabin and its ventilation system. Background technique

[0002] With the rapid development of the power grid, a new type of intelligent prefabricated cabin substation has been widely promoted and applied in China. There have also been inconsistencies in system design. On the one hand, when the prefabricated cabin type substation is working normally, it needs to maintain a closed space. When the external environment is in a bad state, it is necessary to prevent the internal electrical equipment from being affected by moisture, sand, dust, etc., which will cause a short circuit of the equipment and cause damage to the normal operation of the entire power grid. On the other hand, since there are a large number of heating components installed in the substation, if there is no heat dissipation channel, the heat emitted by the heating components cannot be discharged in time, and the high temperature genera...
