Embodiment Construction
[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0018] As an embodiment of the present invention, a fireproof structure of a power distribution cabinet includes a box body 1 and a door body 2 hinged on the box body 1. The side wall of the box body 1 is provided with a number of first ventilation holes 1a. There is a housing chamber 1b inside, and the upper part of the housing chamber 1b is connected with a turret 3 by means of bearings. The front part of the turret 3 is equipped with a gas tank 4, which is filled with a certain pressure of fire extinguishing agent. The outer wall of the tank 4 is provided with a spout 4a, the spout 4a is plugged with an end cover 5, the end cover 5 is in contact with a heat-sensitive support 6, a fixed block 7 is arranged in the accommo...

The invention discloses a fireproof structure of a power distribution cabinet. The fireproof structure comprises a box body and a door body hinged to the box body. A plurality of first ventilating holes are formed in the side wall of the box body, an accommodation cavity is formed in the box body, a rotating rack is assembled on the upper part of the accommodation cavity in a bearing connecting mode, a gas tank is assembled on the front part of the rotating rack, the gas tank is filled with an extinguishant at a certain pressure, a spray head is arranged on the outer wall of the gas tank, an end cover is inserted onto the spray head, a thermal sensitive support part is in contact with the end cover, and a sealing plate is slidably assembled on the side wall in the box body. By means of thegas tank with the accommodation cavity filled with the extinguishant at a certain pressure, the accommodation cavity is extinguished. Meanwhile, the sealing plate is driven to move by means of powerof the gas tank to close a first ventilating hole in the box body so as to isolation circulation between the accommodation cavity and external air to extinguish the fire in an assisted manner.
Description
technical field [0001] The invention relates to the field of fireproof structure of a power distribution cabinet, in particular to a fireproof structure of a power distribution cabinet. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final stage of the power distribution system. During the use of the power distribution cabinet, since the electronic devices will generate a lot of heat when they are working, it is necessary to open a through hole on the outer wall of the power distribution cabinet for the circulation of air, but if the electronic device catches fire, the through hole It will accelerate the burning of electronic devices. Contents of the invention [0003] In view of this, the object of the present invention is to propose a fireproof structure of a power distribution cabinet to solve all or one of the problems in the background technolog...
