Switch cabinet

Abstract

The invention discloses a switch cabinet which comprises a switch cabinet body (1). A plurality of line outgoing holes (6) are arranged at the bottom of the switch cabinet body (1), the switch cabinet body (1) is a door opening mechanism in the middle, the door opening mechanism is provided with a handle (2), an exhaust fan (4) is arranged at the top of the switch cabinet body (1), a semicircular dust cover (3) covers outside the exhaust fan (4) and is provided with a plurality of exhaust holes (5), and a filter screen (7) is arranged on the exhaust holes (5). The exhaust fan is arranged at the top of the switch cabinet body, and the dust cover is arranged above the exhaust fan, so that ventilation and heat radiation are guaranteed while dust can be effectively prevented from entering, and cleanness inside the switch cabinet is guaranteed. The switch cabinet is simple in design, low in cost, effective in ventilation and heat-radiation and beneficial to wide popularization.

Description

technical field [0001] The invention relates to a switch cabinet and belongs to the technical field of power distribution systems. Background technique [0002] With the rapid development of urban modernization and the continuous transformation and renewal of urban power distribution systems, the switchgear is a widely used power equipment, which is specifically used for the outside line to enter the main control switch in the switchgear, and then enter the sub-control switch. Circuits are set according to their needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. The existing switch cabinets are generally sealed structures, in order to effectively prevent dust from entering, but the heat generated by the switch cabinets during work It is large and requires heat dissipation. Some existing expensive switch cabinets use small air conditioners to cool down. The cost is too high and it is not suitable for large-scale promotion. Co...
