In above-mentioned technical proposal, it is preferred that be provided with several electromagnet on the cabinet body, be arranged in the cabinet door
There is the patch matched with the electromagnet, is also respectively provided with sealing joint strip in the cabinet body and the cabinet door.
This high-tension switch gear is placed in the closed space full of nitrogen, can thus completely cut off extraneous ash
Dirt, and the stabilization that extraneous climate change keeps internal temperature and humidity is not feared.It is flowed always in the intracorporal nitrogen of cabinet simultaneously
It is dynamic, play the role of radiating to high-tension switch gear.The present invention replaces normal air to cool down with nitrogen, reduces in air
Oxygen and fever high-tension switch gear occur oxidation reaction, greatly improve the service life of high-voltage switch gear, reduce
The incidence of failure.There are also datonation-inhibition effects for nitrogen simultaneously, can be reduced the danger of fire when high-tension switch gear explodes and fire behavior occurs
Evil guarantees the other equipment safety outside cabinet body.
Compared with prior art, this high-tension switch gear is sealed in the cabinet body full of nitrogen, has completely cut off extraneous ash
Dirt and impurity can allow constant temperature and humidity in cabinet body simultaneously, due to the contact of not no oxygen, prevent the generation of oxidation reaction, greatly
It improves the service life of high-voltage switch gear, reduce the incidence of failure.Moreover, after high-voltage switch gear explodes,
It also can be reduced the generation of fire under the inhibition of nitrogen.
Detailed description of the invention
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is figure schematic internal view of the present invention.
Specific embodiment
Present invention is further described in detail With reference to embodiment.
