Background technique
Breaker is electrical equipment most important, most complicated in GIS, pass of the circuit breaker housing as killer switch equipment
Key member is naturally extremely important, and the reasonability of structure design directly influences the long-term running security reliability of breaker.Cause
This, it is necessary to rational Design on Plane and verifying are carried out to the structure of breaker and its shell.
The sulfur hexafluoride gas of high pressure is full of in breaker, this gas once leaks, it will causes not to equipment
Appreciable loss, existing breaker use circumscribed flange substantially, and this structure is unfavorable for guaranteeing the air-tightness of gas, easily
It leaks, so needing reasonable flange arrangement to prevent the generation of leakage.Followed by now with breaker structure on not
Rationally, the design of air inflation nozzle and vent valve is unreasonable, and when equipment is unstable, adjustability is very poor.
Utility model content
The technical problems to be solved in the utility model is that gas easily leaks in existing circuit breaker housing and adjustability is poor
Problem.
To solve the above-mentioned problems, the utility model provides a kind of GIS circuit breaker housing to solve the above problems, specifically
Technical solution is as follows: a kind of GIS circuit breaker housing, including columnar shell and air inflation nozzle, the upper side wall setting of the shell
Air inflation nozzle, the outer surface of the shell are arranged multiple flange ports, all mounting flange at the multiple flange port, and the one of the shell
The 4th flange of end installation, the other end install second flange；The 5th flange is installed in one end of nearly 4th flange of shell upper side wall,
First flange is installed in one end of the nearly second flange of the shell upper side wall, and the lower wall of the axle housing installs two third methods
Orchid, the axle center in one axle center and first flange in the third flange is in same straight line；
Retainer plate is installed in the outside of the flange port, and the first flange, third flange, the 5th flange are all disposed within flange
Mouthful inside, the partial threads connecting line that extends to hull outside, the first flange, third flange, the 5th flange and each
From the flange port for passing through bolt clamping body between the retainer plate being connected；Deflation spiral shell is set at the axle center of the second flange
Bolt is arranged between the bleeder screw and second flange and prevents discouraged gasket seal.
Further, stiffening ring is arranged in the circumferential of air inflation nozzle in the shell, and the stiffening ring is hermetically connected with the shell, institute
The rotation for stating the mouth setting dust protection of air inflation nozzle emits.
Further, recessed circle is all arranged in the first flange, third flange, the 5th flange and the surface of flange port connection,
Seal washer is installed in the recessed circle.
The beneficial effects of the utility model are: being provided with stiffening ring at air inflation nozzle, solves perforate band on shell and carry out intensity
The problem of reduction, also increases the air-tightness at air inflation nozzle, and secondly the thickness of flange is greater than the thickness of shell, so in order to subtract
Few aperture on shell, has been arranged in the center of flange for the biggish bleeder screw of aperture, to guarantee the intensity of equipment.
In air-tightness, the principle of gas self-sealing in shell is utilized, flange is arranged in shell, pressure is bigger,
Then air-tightness is better, prevents the equipment bring that leaks to of gas in shell from damaging.

In addition, term " first ", " second " etc. are used for description purposes only, it is not understood to indicate or imply relatively important
Property.In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " connected " " connects
Connect " it shall be understood in a broad sense, for example, it may be being fixedly connected, it may be a detachable connection, or be integrally connected；It can be machine
Tool connection, is also possible to be electrically connected；It can be directly connected, it can also be indirectly connected through an intermediary.For this field
For those of ordinary skill, the concrete meaning of above-mentioned term in the present invention can be understood with concrete condition.In addition, in this reality
With in novel description, unless otherwise indicated, the meaning of " plurality " is two or more.
As shown in figures 1 and 3, the utility model provides a kind of GIS circuit breaker housing, including 1 He of columnar shell
Air inflation nozzle 10 is arranged in air inflation nozzle 10, the upper side wall of the shell 1, and multiple flange ports 14 are arranged in the outer surface of the shell 1, described
All the 4th flange 7 is installed in mounting flange, one end of the shell 1 at multiple flange ports 14, and the other end installs second flange 5；Institute
The one end for stating nearly 4th flange 7 of 1 upper side wall of shell is installed by the 5th flange 8, one end of the nearly second flange 5 of 1 upper side wall of shell
First flange 2 is installed, the lower wall of the axle housing 1 installs two third flanges 6, one axis in the third flange 6
The axle center of the heart and first flange 2 is in same straight line；
Retainer plate 3 is installed in the outside of the flange port 14, and the first flange 2, third flange 6, the 5th flange 8 are all arranged
Inside, the partial threads connecting line that extends to hull outside in flange port 14, the first flange 2, third flange 6, the
Pass through the flange port 14 of 4 clamping body 1 of bolt between five flanges 8 and the retainer plate 3 being respectively connected；The second flange 5
Bleeder screw 11 is set at axle center, is arranged between the bleeder screw 11 and second flange 5 and prevents discouraged gasket seal 12.
The working principle of the utility model is: the diameter of first flange 2, third flange 6, the 5th flange 8 is greater than flange port
14 internal diameter, less than the outer diameter of flange port 14, such first flange 2, third flange 6, the 5th flange 8 are out of shell 1 toward outer cover
On, the outer diameter of retainer plate 3 is equal to the outer diameter of flange port 14, internal diameter is less than the internal diameter of flange port 14, and retainer plate 3 is from outside to internal buckle
On, it is screwed between first flange 2, third flange 6, the 5th flange 8 and retainer plate 3 by bolt 4, is located at the first method to compress
Seal washer 13 between orchid 2, third flange 6, the 5th flange 8 and flange port 14 realizes sealing, lithium when being full of in shell 1
When sulphur gas, the internal pressure of shell 1 will more compress seal washer 13, in the pressing force of bolt 4, in addition the compression of air pressure
Power, realization device have the effect of self-sealing.It is filled with when being filled with gas in shell 1 by air inflation nozzle 10, rotation, which emits can protect, fills
Gas nozzle 10 is not by the destruction of ambient enviroment, and due to having opened hole on shell 1, tapping is easily destroyed, therefore has welded stiffening ring 9 to protect
Demonstrate,prove 1 intensity of shell near air inflation nozzle 10；When needing to lose heart, screws, put after unscrewing bleeder screw 11 to appropriate pressure
Gas bolt 11 is arranged in second flange 5, will not influence the decrease of device in intensity.
As shown in Fig. 2, circumferential setting stiffening ring 9 of the shell 1 in air inflation nozzle 10, the stiffening ring 9 are sealed with shell 1
The rotation of connection, the mouth setting dust protection of the air inflation nozzle 10 emits；Stiffening ring 9 has eliminated on shell 1 in aperture bring intensity
Decrease the problem of, avoid dangerous generation, while stiffening ring 9 and shell 1 are also to be tightly connected, and ensure that the gas of whole device
Close property.
As shown in figure 4, the surface that the first flange 2, third flange 6, the 5th flange 8 and flange port 14 connect all is arranged
Recessed circle, the recessed circle is interior to install seal washer 13；There are also radial directions for pressure of the gas to seal washer 13, so the recessed circle of setting is kept away
Exempt from the displacement that seal washer 13 generates radially and brings security risk so that the leakage of gas occurs.
