Description
Technical field
The utility model is related to GIS equalizing capacitors, especially a kind of GIS equalizing capacitors end cover type expander.
Background technology
With the development of economy, the electricity capacity of power grid increasingly increases.GIS equalizing capacitors have been applied to extra-high voltage neck
Domain.During killer switch separating brake therein, the fluctuation of voltage is very big, very unstable.GIS equalizing capacitors are mainly used to improve
Voltage's distribiuting reduces and recovers voltage build-up rate, the effect of equal piezoelectricity pressure.Therefore this is for the product quality of GIS equalizing capacitors
It is it is required that higher and higher.The place that cannot have any properties of product unstable.
There are cover board and expander in the both ends of GIS equalizing capacitors, this main function is adjusted according to ambient temperature
Save internal pressure.The expander and cover board of existing GIS equalizing capacitors are separated.They connect intermediate demand.Then it is swollen
Swollen device is also required to connect with capacitor body.More connections together add internal space.Therefore the prior art is in operating procedure
There is the defects of very big with the performance requirement aspect of product.This structure greatly affects the efficiency and product of work simultaneously
The stabilization of performance.
The content of the invention
For the deficiencies in the prior art, the utility model provides a kind of GIS equalizing capacitors and is expanded with end cover type
Device can stablize the performance of equalizing capacitor, ensure the quality of equalizing capacitor, make equalizing capacitor safe in power grid, flat
Steady operation, makes customer satisfaction.The technical solution adopted in the utility model is：
A kind of GIS equalizing capacitors end cover type expander including end cap, expansion joint, claims cylinder, seal base；
The expansion joint be equipped with it is multiple, multiple expansion joints cascade to form swelling part；
The expansion joint of the top is welded on end cap lower end, and seal base is welded on the lowermost expansion joint lower part；
Claim jacket casing on expansion joint and be welded in the lower part of end cap；
End cap is equipped with air-filled pore, and the air-filled pore is communicated with space in swelling part；Electrode hole is additionally provided on end cap, electricity
Pole hole is not connected with space in swelling part；
Claim the elongate space for leaving expansion joint in cylinder away from one end of end cap.
Further, the diameter of two neighboring expansion joint is different, the expansion joint of first diameter and the expansion joint of second diameter
It is arranged at intervals.
Further, the material of expansion joint is stainless steel.
Further, elongate space length is referred to as the 15%~20% of swelling part length in cylinder.
The utility model has the advantage of：The utility model provides a kind of new GIS of slight positive pressure state inside holding
Equalizing capacitor end cover type expander improves the utilization rate of inner space；It can be effectively reduced inside GIS equalizing capacitors
The problem of pressure balance, so as to reduce shelf depreciation, stablizes the properties of equalizing capacitor, can ensure GIS equalizing capacitances
Device properties of product are stablized；It is easy for installation.
Description of the drawings
Fig. 1 is the structure composition schematic diagram of the utility model.
Specific embodiment
With reference to specific drawings and examples, the utility model is described in further detail.
As shown in Figure 1, a kind of GIS equalizing capacitors end cover type expander provided by the utility model, including end cap 1,
Expansion joint 2 claims cylinder 3, seal base 4；
The expansion joint 2 is equipped with multiple, and the cascade of multiple expansion joints 2 forms swelling part；Specifically, two neighboring expansion joint
Diameter it is different, the expansion joint 2 of first diameter and the expansion joint 2 of second diameter are arranged at intervals；The material of expansion joint 2 is stainless
Steel, the swelling part peripheral shape formed are similar to the bent flue of smoke exhaust ventilator；
The expansion joint 2 of the top is welded on 1 lower end of end cap, and seal base 4 is welded on the lowermost expansion joint lower part；
Cylinder 3 is claimed to be sleeved on the lower part for being welded in end cap 1 on expansion joint 2；
End cap 1 is equipped with air-filled pore 101, and the air-filled pore 101 is communicated with space in swelling part；It is additionally provided on end cap 1
Electrode hole 102, for installing electrode member；Electrode hole 102 is not connected with space in swelling part；
Operation principle：GIS equalizing capacitors are mounted in one end of GIS equalizing capacitors with end cover type expander, as product
An electrode, outside cover plate for sealing.Then vent plug is packed into air-filled pore, using special air charging system, to expansion joint 2
Inflation claims cylinder 3 to be used for limiting the elongation of expansion joint 2.Claim the elongate space for leaving expansion joint 2 in cylinder 3 away from one end of end cap 1
301；301 length of elongate space is the 15%~20% of swelling part length.
