Description

An outdoor windproof and waterproof switch cabinet of a substation

technical field

The invention relates to the technical field of switch cabinets, in particular to an outdoor windproof and waterproof switch cabinet of a substation.

Background technique

At present, some outdoor switch cabinets of substations are placed outdoors for a long time, especially in seasons with frequent wind and rain. When the wind blows for a long time, the switch cabinets are extremely vulnerable to damage. At present, there are no good windproof measures, and rainwater enters the switch cabinets at the same time. Inside, there is a high possibility of danger, so its waterproof performance is particularly important. However, some existing switchgears have poor waterproof performance. Rainwater easily enters the interior of the outdoor switchgear through the gap between the cabinet body and the door, thus affecting the switchgear. For the normal operation of the cabinet, when the high-voltage circuit in the main cabinet of the switch cabinet leaks electricity, the metal door panel will conduct electricity or store static electricity. Once the operator touches the door panel and the operating elements on the door panel, it will cause electric shock danger. The windproof and rainproof measures of the switchgear are improved so that the switchgear is not easily damaged. At the same time, an outdoor windproof and waterproof switchgear of the substation is proposed to better protect the switchgear from damage and increase the service life of the switchgear.
