Both can be with permanent magnetic actuator vacuum circuit breaker or with the vacuum circuit breaker of spring mechanism, whole cabinet uses air insulation and hexafluoro
Change sulphur gas cells to combine, it is not only compact but also extendible, it is suitable for power distribution automation.Gas-filling cabinet has compact-sized, operation spirit
It lives, interlock the features such as reliable, a variety of different applications (the especially places of bad environments), different users are required equal
Satisfactory technical solution can be provided.The use of sensing technology and newest protective relay, and advanced technical performance and
The assembling scheme of light and flexible can satisfy the different demand of user completely.Gas-filling cabinet is suitable for the small-sized secondary of electric system
Electric substation, switching station, box-type substation, residential quarters, industrial and mining enterprises, megastore, especially suitable for airport, subway, railway
Deng to the higher occasion of power requirement.
Gas-filling cabinet generally comprises gas tank, cable vault and control room, breaker is provided in gas tank, disconnecting switch, ground connection are opened
The main switch blocks such as pass, cable vault are used for connection cables, and control room is for installing various electric meters.Hexafluoro is full of in gas tank
Change sulphur gas, to guarantee the insulating properties between switch block.But gas tank is in use, can more or less have gas and let out
Leakage, if things go on like this, sulfur hexafluoride gas can be fewer and fewer in gas tank, and the insulation performance in gas tank also can worse and worse, and there are one
Fixed security risk.
Therefore, how existing gas-filling cabinet is improved, it is made to overcome the above problem, be those skilled in the art urgently
The problem solved.
Summary of the invention
It is an object of the present invention to provide it is a kind of can automatic supplementary air, and compact-sized, safe and reliable spy
The gas-filling cabinet of different structure.
To achieve the above objectives, the technical solution adopted by the present invention are as follows: a kind of gas-filling cabinet of special construction, including gas tank,
Cable vault and control room are provided with breaker, disconnecting switch and earthing switch in the gas tank, are provided with behaviour in front of the gas tank
Make mechanism, be connected with copper bar below the breaker, insulator is provided on the copper bar, the insulator passes through the gas tank
And enter the cable vault, door-plate is provided in front of the cable vault；It is characterized by:
Lower end is recessed inwardly to form receiving notch in front of the gas tank, and the receiving indentation, there is provided with automatic inflating dress
Set, the self-filler is located in the cable vault, the self-filler include high pressure gas cylinder, air gauge, microcomputer,
First connector, the second connector and the first solenoid valve, first connector one end passes through and is fixedly installed on the gas tank, described
First solenoid valve one end connects the first connector other end, and the first solenoid valve other end connects second connector one
End, the second connector other end connect the high pressure gas cylinder, and the air gauge is fixedly installed on the gas tank, for monitoring
Air pressure in the gas tank, the microcomputer are fixedly installed on the gas tank；
Sulfur hexafluoride gas is loaded in the high pressure gas cylinder, and air pressure is higher than gas in the gas tank in the high pressure gas cylinder
Pressure；The air gauge and first solenoid valve are electrically connected the microcomputer；When the air gauge monitors in the gas tank
When air pressure is lower than setting value, for the air gauge by pressure signal transmission to the microcomputer, the microcomputer, which issues signal, makes described the
One solenoid valve is opened, and the sulfur hexafluoride gas in the high pressure gas cylinder enters the gas tank, until air pressure reaches in the gas tank
Normal value.
As an improvement, the self-filler further includes second solenoid valve and third connector, the second solenoid valve one
End connects first connector, and the second solenoid valve other end connects third connector one end, and the third connector is another
End is across the cable vault, for connecting sulfur hexafluoride gas inflation system.
Preferably, the high pressure gas cylinder removably connects second connector, second inner nosepiece wall is extended
Stop collar, is provided with elastic seal ring between the high pressure gas cylinder and second connector, described in the elastic seal ring contradicts
Stop collar；High pressure gas cylinder can be replaced in sulfur hexafluoride gas using complete later；Elastic seal ring can increase high pressure gas cylinder
And the second leakproofness between connector.
The opening of the high pressure gas cylinder is provided with valve inside, and thimble is provided in second connector, and the thimble is solid
Surely it is set on the stop collar；When the high pressure gas cylinder and second connector separate, the valve inside closes the high pressure
Gas cylinder, when the high pressure gas cylinder is completely attached on second connector, the thimble opens the valve inside, makes the high pressure
Gas cylinder is connected to second connector.The setting of thimble and valve inside guarantees that hexafluoro will not occur in cargo handling process for high pressure gas cylinder
Change sulphur leakage.
Preferably, first connector is T-type three-way connection, second connector is two pass joint of L-type, the third
Connector is two pass joint of linear type；First solenoid valve and the second solenoid valve are connected to described in left-right direction respectively
One connector both ends, the high pressure gas cylinder are arranged along the longitudinal direction by second connector, and the third connector is in left-right direction
Across the cable vault.Since space is limited in gas-filling cabinet, in order to utilize space as far as possible, two solenoid valves are laterally set
It sets, guarantees that high pressure gas cylinder has enough volumes.
As an improvement, offering observation window on the door-plate, the observation window is directed at the air gauge and the microcomputer.Just
The state shown by the barometric reading of observation and microcomputer.
Compared with prior art, the invention has the following advantages that the equal leans back of copper bar and insulator in this programme, so that
There are enough spaces to be formed in front of gas tank and accommodates notch.Self-filler is mounted on receiving indentation, there, will not be to original inflation
The size of cabinet generates any influence.
It is noted that self-filler can not only carry out sulfur hexafluoride gas supplement with high pressure gas cylinder, but also can be with
Sulfur hexafluoride gas inflation system outside connection carries out tonifying Qi.Two ways can more need, select one use or both it is same
When use.Specifically, when use occasion only has single gas-filling cabinet, it is suitble to carry out tonifying Qi using high pressure gas cylinder, in high pressure
Sulfur hexafluoride gas is using totally rear replacement high pressure gas cylinder in time in gas cylinder, or is inflated to high pressure gas cylinder；It is using
When occasion has multiple gas-filling cabinets, each gas-filling cabinet can be connected by third connector into sulfur hexafluoride gas inflation system, existing
Field one relatively large sulfur hexafluoride gas cylinder of arrangement, can for a long time be inflated all gas-filling cabinets.
In addition, self-filler is apolegamy component, client can more be chosen to install.Installation is not needed to fill automatically
Gas tank only need to be used to connect the mounting hole of air gauge and the first connector, be blocked with plug by the gas-filling cabinet of device of air.
