Description
Technical field
The utility model relates to a kind of electrical auxiliary service, and more particularly, it relates to a kind of breaker cabinet.
Background technology
Gas-filling cabinet is switchgear of new generation, whole cabinet adopts air insulation to combine with sulfur hexafluoride gas compartment, not only compact but also extendible, be applicable to power distribution automation, gas-filling cabinet has compact conformation, flexible operation, the feature such as to interlock reliable, to various different application scenario (particularly the place of bad environments), different users requires all can provide gratifying technical scheme, gas-filling cabinet is applicable to the small-sized secondary substation of electric power system, switching station, box-type substation, residential quarters, industrial and mining enterprises, megastore, be specially adapted to airport, subway, railways etc. require higher occasion to electricity consumption.
In gas-filling cabinet, closely packed has the gas of high insulating property, and in the gas-filling cabinet course of work, its internal circuit element produces amount of heat thus causes insulating gas expanded by heating wherein, if appropriate process can not just have the danger of blast, and common gas-filled tube is generally no more than 40 degree because this reason limits its Applicable temperature.
In prior art, be disclose a kind of gas-filling cabinet explosion-protection equipment in the Chinese utility model patent prospectus of CN201320595376.2 in the patent No., comprise and be filled in burst disk in gas tank base plate perforate perforate and grommet thereof, be overlying on the sealing ring on burst disk outward, and by securing member that this burst disk and grommet thereof, sealing ring connect with gas tank base plate, the beneficial effect of this utility model is: use a kind of gas-filling cabinet decompression anti-explosion device, can play explosion-proof object.
Although the gas-filling cabinet explosion-protection equipment of this utility model arranges pressure relief device, but the insulating gas of filling in gas-filling cabinet is sulphur hexafluoride, although sulphur hexafluoride itself is to human non-toxic, harmless, but it is a kind of greenhouse gases, its monomolecular greenhouse effect are 2.2 ten thousand times of carbon dioxide, one of 6 kinds of greenhouse gas being prohibited in Kyoto Protocol to discharge, this sulphur hexafluoride discharged in gas-filling cabinet by this pressure relief device can cause serious pollution to environment, and by needing again after this pressure relief device pressure release to supplement sulphur hexafluoride in gas-filling cabinet, very inconvenient.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of explosion-proof gas-filling cabinet that can not discharge sulphur hexafluoride.
For achieving the above object, the utility model provides following technical scheme: a kind of 1V24 gas-filling cabinet, comprises gas-filling cabinet body, wherein: the pneumatic die cushion described gas-filling cabinet body being provided with hollow, contracting mechanism is provided with, the inside UNICOM of described gas-filling cabinet body and described pneumatic die cushion in described pneumatic die cushion.
By adopting technique scheme, pneumatic die cushion is utilized to collect gas because of expanded by heating in described gas-filling cabinet, play the effect of balanced gas-filling cabinet air pressure inside, described contracting mechanism when gas expansion by gas compression, after described gas-filling cabinet temperature declines, described gas can be got back in described gas-filling cabinet again, and described insulating gas is reused without the need to again inflating.
The utility model is set to further: described contracting mechanism is set to bellows, the sidewall of described pneumatic die cushion offers through hole, described bellows diameter is greater than described through-hole diameter, and one end of described bellows is sealedly connected on the outside of described through hole, and the other end is arranged in closing.
By adopting technique scheme, described bellows has good rigidity, shrinkage and sealing concurrently, has both guaranteed to shrink to change pneumatic die cushion internal volume, ensures that again insulating gas can not be revealed.
The utility model is set to further: described pneumatic die cushion is arranged on the inside of described gas-filling cabinet body.
By adopt technique scheme, described gas-filling cabinet body plays a protective role to pneumatic die cushion, prevents pneumatic die cushion to be exposed to outside air and is exposed to the weather, make described pneumatic die cushion contaminated, corrosion.
The utility model is set to further: described bellows is provided with directive wheel away from one end of through hole, and described bellows to be rolled with the inwall of pneumatic die cushion by directive wheel and is connected.
By adopting technique scheme, described directive wheel decreases the frictional force of bellows and pneumatic die cushion inside, thus makes the contraction of described bellows, expansion more rapid, and release of pressure ability is better.
Compared with prior art, explosion-proof gas-filling cabinet of the present utility model utilizes the contracting mechanism of pneumatic die cushion and pneumatic die cushion inside to collect the insulating gas of cabinet internal expansion, both alleviate the gas pressure of at high temperature gas-filling cabinet inside, and prevent again the discharge of insulating gas to the pollution alleviated.
