Less than longitudinal depth of cable vault 5, bus-bar room 3 is arranged on the top side of breaker chamber 1 and longitudinal to longitudinal depth at face to the back side
More than longitudinal depth of breaker chamber 1, the rear of breaker chamber 1 is formed depth with the top side of the bottom side of bus-bar room 3 and cable vault 5
Have remaining space, be provided with pressure release passage 4 in the remaining space, pressure release passage 4 respectively with breaker chamber 1, bus-bar room 3 and cable
Room 5 is fixedly connected and is shared by three, and the width of pressure release passage 4 is consistent with the width of gas-filling cabinet.So it is provided with
The depth for reducing Inflatable cabinet body of effect, improves the space availability ratio in Inflatable cabinet body, reduces the occupation of land of gas-filling cabinet
Area, has saved production cost.
As shown in Figures 2 and 3, pressure release passage 4 is rectangular box structure, and rectangular box structure is mainly to be covered using 2mm thickness
Aluminium zinc steel plate passes through bending, assembles.The bottom of rectangular box is bolted to connection with cable vault 5, and rectangle frame
Pressure releasing plate 6 is provided with the bottom opening of body, the Main Function of pressure releasing plate 6 will can be produced in cable vault 5
Gases at high pressure are timely discharged.Pressure releasing plate 6 is rectangular plate-like structure, and the type of attachment of pressure releasing plate 6 can be by it
One side makes the side be fixedly connected with the bottom of pressure release passage 4 by fixing bolt, and remaining side is consolidated with screw
Fixed connection, these screws can all be pulled out in the presence of certain force, when cable vault 5 produces gases at high pressure, high pressure
Gas can be by these screws to washing open, and the bolted side of pressure releasing plate 6 will bend, then gases at high pressure
Can just enter into pressure release passage 4.So setting can cause that pressure releasing plate 6, will not when by gases at high pressure to washing open
The complete bottom for departing from pressure release passage 4, still suffers from a part and is connected with the bottom of pressure release passage 4 on pressure releasing plate 6,
Pressure release passage 4 will not be damaged, good protective effect is served to pressure release passage 4.In other embodiments, pressure is released
Putting plate 6 can also set the fasteners such as bolt in the right angle of rectangular plate-like structure, and other positions of rectangular plate-like structure set
Put mode connects for screw or the attachment means that can be opened in the presence of certain force such as be welded to connect, so when in cable vault 5
It is not that the position being fastenedly connected will be opened on pressure releasing plate 6 when producing gases at high pressure, then the straight of fastening bolt is set
Will be bent at angle, gases at high pressure can be just entered into pressure release passage 4 by the opening opened.
The top of pressure release passage 4 is bolted to connection with bus-bar room 3, is set in the top open part of pressure release passage 4
There is pressure relief device 7, pressure relief device 7 is fixedly connected by ring flange with the sealing plate at the top of pressure release passage 4, pressure
Gas release channel is provided with release device 7, the sealing structures such as rupture pressure disc are provided with gas release channel.When bus-bar room 3
During middle generation gases at high pressure, the sealing device such as rupture pressure disc will be by gases at high pressure to washing open, and gases at high pressure can just be released by pressure
The gas release channel put in device 7 is entered into pressure release passage 4.
Pressure release passage 4 is the front end face of pressure release passage 4 near the side of breaker chamber 1, the front end face of pressure release passage 4 with it is disconnected
Road device room 1 is bolted to connection, and pressure relief device 8 is again provided with pressure release passage 4, and pressure relief device 8 passes through
Ring flange is fixedly connected with the sealing plate of the front end face of pressure release passage 4, and gas release channel, gas are provided with pressure relief device 8
The sealing structures such as rupture pressure disc are provided with body release channel.When gases at high pressure are produced in breaker chamber 1, the sealing dress such as rupture pressure disc
Putting will be by gases at high pressure to washing open, and gases at high pressure can just be entered into by the gas release channel in pressure relief device 8 and let out
In pressure passageway 4.
The frame of the left and right sides of pressure release passage 4 sets up separately and is equipped with relief hole 10, and relief hole 10 is directly connected with external environment condition
Connect, the gases at high pressure in pressure release passage 4 can be quickly discharged in external environment condition, the back of pressure release passage 4 and gas-filling cabinet
Sealing plate 9 is provided with the rear end face of homonymy, sealing plate 9 can be carried out effectively to the gases at high pressure that pressure relief device 8 is released
Stop, so setting can cause that gases at high pressure in pressure release passage 4 can only be discharged by relief hole 10 come external environment.
Pressure release passage 4 is switched off device room 1, bus-bar room 3, cable vault 5 and shares, when in cable vault 5 due to arc fault
When producing gases at high pressure, pressure releasing plate 6 can be opened by gases at high pressure, so that the gases at high pressure in cable vault can be by letting out
In the environment that pressure passageway 4 is discharged to the outside in time.When gases at high pressure are produced due to arc fault in bus-bar room 3, pressure
Release device 7 will be opened by gases at high pressure so that gases at high pressure are by the externally discharged ring of relief hole 10 on pressure release passage 4
In border.When gases at high pressure are produced due to arc fault in breaker chamber 1, pressure relief device 8 will be beaten by gases at high pressure
Open, gases at high pressure are entered into pressure release passage 4 by opening, then by the externally discharged environment of relief hole 10.And pressure release is led to
The height in road 4 is the twice of height at the opening of pressure relief device 8, and so setting can be such that the pressure releasing plate 6 will not be let out
The destruction of the mesohigh gas of pressure passageway 4, cable vault 5 will not also therefore suffer from influence.
The specific embodiment of gas-filling cabinet pressure release passage of the present utility model, the concrete structure of gas-filling cabinet pressure release passage with it is above-mentioned
