Safety devices for power distribution cabinets

Abstract

The invention discloses a safety device of a power distribution cabinet. The power distribution cabinet comprises a power distribution cabinet box and the safety device mounted in the power distribution cabinet box, a mounting cavity is formed in the power distribution cabinet box, a power distribution cabinet main board is assembled in the mounting cavity, and more than one plug-in main board element is arranged on the power distribution cabinet main board. Two guide tracks are arranged on the upper surface and the lower surface of the mounting cavity, corresponding guide-track grooves are formed in the upper end and the lower end of the safety device and directly face the guide tracks, and the safety device is slidably mounted on the guide tracks. The safety device comprises a protectivemain board, a rotating board is arranged in the middle of the protective main board, a rotating shaft is arranged in the middles of the upper end and the lower end of the rotating board, and the rotating board is rotatably mounted in a rotating cavity in the middle of the protective main board through the rotating shaft. When flames appear, electronic elements on the main board are effectively pulled out and turned by 360 degrees to protect safety of the elements, the safety device has a fire-extinguishing function and is safer to use, and economic loss caused by fire disasters is reduced.

Description

technical field [0001] The invention relates to the field of power distribution cabinets, in particular to a safety device for a power distribution cabinet. Background technique [0002] When the outdoor power distribution cabinet is in use, fires often occur due to short circuit or other reasons. The traditional method generally sets up an alarm system. However, after the alarm, the staff arrives at the scene and then extinguishes the fire. Often the entire power distribution cabinet has been burned down. The loss of the device is relatively large, resulting in the loss of economic costs, and the protection measures for the components are not enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a safety device for a power distribution cabinet, which can effectively pull out the electronic components on the main board when a flame occurs, and rotate 360 ​​degrees to protect the safety of each component. safet...
