At very huge economic loss, it is ensured that breaker reliability of operation just must often monitor the indices of breaker, especially
It is SF6 gas, it is necessary to reach the regulation in relation to standard, SF6 breaker is made to keep good working order for a long time.
Existing sensor and pressure vessel ask that sealing is completed by " O " type rubber seal, traditional gauge sensor structure
Although can seal, there is following defect: " O " type sealing ring material is rubber, of long duration through oil immersion, light radiation meeting aging
(general 2~3 years) rubber, which follows the string, to be caused to leak；The temperature use scope of rubber is limited, especially -40 DEG C of low temperature with
Under, rubber, which generates embrittlement and follows the string, to be caused to leak, it is therefore desirable to a kind of novel dedicated biography of telemetering type SF6 gas density is relay
Sensor structure.
Utility model content
(1) the technical issues of solving
In view of the deficiencies of the prior art, it is special to provide a kind of novel telemetering type SF6 gas density is relay for the utility model
With sensor structure, solves and use " O " type rubber seal to complete sealing between traditional sensor and pressure vessel, still
When " O " type rubber seal uses for a long time or the operation is stable is spent lower than -40, will cause rubber and follow the string leads to asking for leakage
Topic.
(2) technical solution
To achieve the above objectives, the technical scheme adopted by the utility model is that: a kind of novel telemetering type SF6 gas density is after
Electric appliance sensor special structure, including pressure guiding joint, the left side of the pressure guiding joint offer the first assembly gas chamber, and described
It is provided with soft state red copper pad in one assembly gas chamber, the left side of the soft state red copper pad is overlapped with sensor main body, the sensing
The left side of device main body offers the second assembly gas extremely.
Preferably, the first assembly gas chamber inner wall is provided with internal screw thread, and the internal screw thread is threadedly coupled with external screw thread, institute
State the outer surface that sensor main body is arranged in external screw thread.
Preferably, the right side of the soft state red copper pad offers through-hole, and the diameter of through-hole is mutually fitted with sensor main body
Match.
Preferably, the size of the soft state red copper pad is adapted with the size of the first assembly gas chamber.
(3) beneficial effect
The utility model has the beneficial effects that:
1, the novel telemetering type SF6 gas density is relay sensor special structure, by soft state red copper pad, through-hole, leads
Mutual cooperation between crimp head and sensor main body, soft state red copper pad are located between the first assembly gas chamber and sensor main body,
Soft state red copper pad can prevent rubber because oil immersion and light radiation problem lead to aging, make soft state red copper as sealing element
Pad, which can be used for a long time, not to be leaked, will not be generated cold gum embrittlement issue, can not generated leakage at low temperature, can protect
Guarantee the service life of the utility model while demonstrate,proving leakproofness.
2, the novel telemetering type SF6 gas density is relay sensor special structure, by the way that internal screw thread and external screw thread is arranged,
Soft state red copper pad is soft state, is squeezed and deformed to fill the fine gap of sealing surface by threaded tightening force, makes sensor main body
Connection between the first assembly gas chamber is even closer, makes the better tightness of the utility model.
