Description
Technical field
The utility model belongs to high voltage external insulation technical field, is especially applicable to improve the horizontal field of high-voltage breaker explosion chamber insulator external insulation, high altitude localities.
Background technology
Damage to crops caused by thunder long-standing problem power network safety operation, the gesture of lightning strike accident in aggravation of supergrid, the especially switchgear of transformer station.In recent years, having there is a lot of Lightning Incoming Wave and caused breaker fracture external insulation flashover accident in the Yunnan-Guizhou Plateau being located in heavily thunderbolt, High aititude, causes substation bus bar to trip, have a strong impact on the safe and stable operation of electric power system.
According to relevant regulatory requirements, high altitude localities equipment outer insulation needs to revise.Found by investigation, current most circuit breaker external insulation insulator did not all carry out height above sea level correction, this very likely causes circuit breaker external insulation level to lose with transmission line external insulation level coordinating under High aititude, after the Lightning Incoming Wave on circuit invades transformer station, arc-extinguishing chamber of circuit breaker insulator external insulation is caused to puncture.Meanwhile, primary cut-out equipment price is expensive, quantity is many, all changes as requested and is difficult to accomplish.Therefore, how improving existing high-voltage breaker explosion chamber external insulation level in high altitude localities is a kind of problem of being eager to solve.
Based on above analysis, the utility model utilizes the portable pressure-equalizing device of high-voltage breaker explosion chamber insulator to improve high-voltage breaker explosion chamber external insulation level.
Utility model content
The purpose of this utility model is to provide a kind of portable pressure-equalizing device for improving existing high-voltage breaker explosion chamber insulator external insulation level, solves current high altitude localities and the problem of flashover easily occurs the primary cut-out external insulation not carrying out height above sea level correction.
The utility model is realized by following technical proposal:
The portable pressure-equalizing device of a kind of high-voltage breaker explosion chamber insulator, the utility model is characterised in that: comprise the semicircular spill jack ring body of two end band jacks, two end band plugs semicircular male tab ring body, be positioned at male tab ring body two ends silver coating male tab, be positioned at spill jack ring body two ends spill jack, lay respectively at spill jack ring body and two the fastening semi-rings be connected by set bolt by connecting rod inside male tab ring body;
It connects and mounting structure is:
1) silver coating male tab and the grafting of spill jack, the conductivity that silver coating is good, after ensureing docking, spill jack ring body and male tab ring body form a uniform electric field ring, to realize uniform voltage function;
2) two fastening semi-rings are linked to be a fastening ring body through set bolt;
3) fastening ring body is connected by connecting rod with uniform electric field ring, forms a complete portable pressure-equalizing device.
The portable pressure-equalizing device of the utility model high-voltage breaker explosion chamber insulator is anchored on the metal flange shell of interrupting porcelain insulator by fastening ring body, and the portable pressure-equalizing device subtend in top, two, bottom is installed.
The beneficial effects of the utility model are:
A, utilize portable pressure-equalizing device of the present utility model, the external insulation level of existing primary cut-out can be improved, reduce high altitude localities primary cut-out external insulation flashover problem, improve safe stability of power system;
The portable pressure-equalizing device of b, the utility model according to on-the-spot actual demand, can be arranged on high-voltage breaker explosion chamber insulator quick, portablely, has the features such as easy to assembly, excellent effect.
The utility model content is set forth further below in conjunction with accompanying drawing and example.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is assembling effect figure of the present utility model;
Fig. 3 is installation design sketch of the present utility model.
Embodiment
See Fig. 1, Fig. 2, Fig. 3,1, the portable pressure-equalizing device of high-voltage breaker explosion chamber insulator, the utility model is characterised in that: the semicircular male tab ring body 2 comprising semicircular spill jack ring body 1, the two end band plug of two end band jacks, the silver coating male tab 3 being positioned at male tab ring body 2 two ends, be positioned at spill jack ring body 1 two ends spill jack 4, lay respectively at spill jack ring body 1 and two the fastening semi-rings 5 be connected by set bolt 6 by connecting rod 7 inside male tab ring body 2;
It connects and mounting structure is:
1) silver coating male tab 3 and spill jack 4 grafting, the conductivity that silver coating is good, after ensureing docking, spill jack ring body 1 and male tab ring body 2 form a uniform electric field ring 9, to realize uniform voltage function;
2) two fastening semi-rings 5 are linked to be a fastening ring body 8 through set bolt 6;
3) fastening ring body 8 is connected by connecting rod 7 with uniform electric field ring 9, forms a complete portable pressure-equalizing device.
The portable pressure-equalizing device 12 of the utility model high-voltage breaker explosion chamber insulator is anchored on the metal flange shell 10 of interrupting porcelain insulator 11 by fastening ring body 8, and the portable pressure-equalizing device subtend in top, two, bottom is installed.Effect is installed as shown in Figure 3.
