Fire extinguishing protection power distribution cabinet

Abstract

The embodiment of the invention discloses a fire extinguishing protection power distribution cabinet. The cabinet comprises a cabinet body, a power distribution cabinet main board is fixed on a mounting plate; the power distribution cabinet main board is provided with a first connecting plug. A supporting plate is arranged opposite to the mounting plate; a mounting cavity is formed between the supporting plate and the mounting plate; a sliding groove mechanism is arranged between the supporting plate and the mounting plate; a sliding seat is arranged in the sliding groove mechanism; a mountingbox is arranged on the sliding seat; a door opening-closing mechanism is arranged at a front end of the mounting box; a protective main board is arranged in the mounting box, a second connecting plugis arranged on the protective main board; the supporting plate is further provided with an air bag and a driving mechanism, inert gas is stored in the air bag, the air bag abuts against a rear end ofthe mounting box and is connected with a first control valve through a first air supply pipe, the first control valve is connected with a sand blasting device, the sand blasting device is fixed to anouter wall of the mounting box and faces the power distribution cabinet main board, and the driving mechanism is in transmission connection with the rear end of the mounting box. Inert gas can be sprayed outwards through the air bag, sand can be sprayed outwards through the sand spraying device, fire extinguishing is achieved, and the fire extinguishing speed and effect are improved.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of power equipment, in particular to a fire-extinguishing and protective power distribution cabinet. Background technique [0002] The power distribution cabinet is the terminal equipment of the power distribution system, which plays the role of connecting the previous and the next, especially the switch assembly that controls the power equipment is set in the power distribution cabinet. Therefore, it is very important to ensure the stable operation of the power distribution cabinet. [0003] As the types of power components in the power distribution cabinet become more and more integrated, a large amount of heat will be generated during operation. If the heat cannot be dissipated in time, it will easily lead to the accumulation of heat in the power distribution cabinet. , Especially when a short circuit occurs in some parts of the power distribution cabinet, causing a fire. Not only caus...

Problems solved by technology

[0003] As the types of power components in the power distribution cabinet become more and more integrated, a large amount of heat will be generated during operation. If the heat cannot be dissipated in time, it will easily lead to heat accumulation in the power distribution cabinet. , especially when some components in the power distribution cabinet are short-circuited, causing a fire

It not only causes damage to the distribution cabinet, but also directly affects the safety of electricity use.

In the prior art, only a flame sensor or a smoke sensor is installed in the distribution box, but no automatic fire extinguishing mechanism is installed, which easily delays the fire extinguishing time and causes irreparable losses in the distribution box.
