Abstract
The utility model provides a seal ring used for a vacuum circuit breaker, which belongs to high voltage switch cabinet technology field and is capable of resolving problems of bad sealability of the existing vacuum circuit breaker seal ring. The seal ring used for the vacuum circuit breaker of the utility model is arranged between a solid sealed pole or an insulated barrel and an insulated oversleeve in the vacuum circuit breaker, the inner side face of the seal ring is larger than the external side face of the seal ring, two end faces of the seal ring are inclined, and the inclined directions of two end faces are opposite. The seal ring of the utility model has advantages of simple structure, good sealability, etc.
Description
Technical field
The utility model belongs to the high-tension switch cabinet technical field, relates to a kind of sealing ring, particularly a kind of sealing ring that is used for vacuum circuit-breaker.
Background technology
Vacuum circuit-breaker in the high-tension switch cabinet comprises pole or insulating cylinder, insulating sleeves, insulated tension pole etc., insulating sleeves is pole or the requisite accessory of insulating cylinder fit on, there are many problems in can cooperating, especially exist cooperation not tight, there is the space, is easy to generate the air gap creepage phenomenon.Therefore, in insulating sleeves and pole or insulating cylinder assembling, introduce sealing ring and solve this problem.The sealing ring operation is very easy, sealing ring need only be inserted in pole or insulating cylinder up and down on the line outlet cylindrical, again insulating sleeves is inserted in, be close to sealing ring, compress and be in place, just can play the sealed insulation effect, eliminate the air gap, prevent that creepage phenomenon from producing, stop discharge generation, guarantee that electric equipment is safe and reliable to operation.
What adopt mostly at present is that its cross section is circular sealing ring, there is some problems, mainly be the sealing circle with pole or insulating cylinder and insulating sleeves between be close to sealing, poor sealing for line contacts, be easy to produce the space, thereby produce the air gap creepage phenomenon.Simultaneously, the cross section is easy in installation and use and can rolls for circular sealing ring, and its steadiness is also bad, and sealing ring takes place to roll and also to a certain degree reduced its sealing.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, proposed a kind of simple in structure, good airproof performance and install and use in the sealing ring that is used for vacuum circuit-breaker that can not roll.
The purpose of this utility model can realize by following technical proposal: a kind of sealing ring that is used for vacuum circuit-breaker, be arranged between the pole or insulating cylinder and insulating sleeves in the vacuum circuit-breaker, it is characterized in that: the medial surface of described sealing ring is greater than its lateral surface, the both ends of the surface of described sealing ring are obliquely installed, and the incline direction of above-mentioned two end faces is opposite.
Sealing ring in use is inserted in sealing ring on pole or the insulating cylinder earlier, and the medial surface of sealing ring abuts against on the outer wall of pole or insulating cylinder, insulating sleeves is inserted on pole or the insulating cylinder again.Firmly squeeze and push away insulating sleeves, that inclined end face outside insulating sleeves can be positioned at along sealing ring up moves and is close on the inwall of insulating sleeves until the whole lateral surface of sealing ring.The sealing ring generation deformation that is squeezed this moment, its inside and outside side can be close to respectively on the inwall of the outer wall of pole or insulating cylinder and insulating sleeves, simultaneously, between the inwall of the outer wall of sealing ring and pole or insulating cylinder and insulating sleeves by face contact seal.Therefore, improved the sealing of sealing ring greatly.
At above-mentioned a kind of sealing ring that is used for vacuum circuit-breaker, the gradient of described sealing ring both ends of the surface is 1～50.
Gradient is the tangent of an angle value that end face and medial surface form.Best selection is that described gradient is 5～20.
At above-mentioned a kind of sealing ring that is used for vacuum circuit-breaker, the gradient of described sealing ring both ends of the surface is inequality.
Sealing ring is when installing and using, and high that end face of its gradient is interior, and gradient is outside low.
Compared with prior art, this sealing ring is flat, and its medial surface and lateral surface carry out face contact seal with pole or insulating cylinder and insulating sleeves respectively.Simultaneously, the both ends of the surface of its sealing ring are obliquely installed, when installing and using, its sealing ring can be squeezed and produce deformation the inside and outside side of sealing ring can be close to respectively on the inwall of the outer wall of pole or insulating cylinder and insulating sleeves, and its sealing improves greatly.This ring structure is simple, good airproof performance.
Description of drawings
Fig. 1 is the cutaway view of this sealing ring.
Fig. 2 is the three-dimensional structure diagram of this sealing ring.
Among the figure, 1, sealing ring; 2, lateral surface; 3, medial surface; 4, end face.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As illustrated in fig. 1 and 2, originally the sealing ring 1 that is used for vacuum circuit-breaker is arranged between the pole or insulating cylinder and insulating sleeves in the vacuum circuit-breaker, and the medial surface 3 of sealing ring 1 is greater than its lateral surface 2, its both ends of the surface 4 are obliquely installed, and the incline direction of two end faces 4 is opposite.The gradient of sealing ring 1 both ends of the surface 4 is inequality, and the gradient of one of them end face 4 is 12, and the gradient of another end face 4 is 14.
Sealing ring 1 in use, gradient is that 14 end face 4 is inserted in sealing ring 1 on pole or the insulating cylinder inwardly, then insulating sleeves is inserted in pole or the insulating cylinder and firmly squeezes and push away insulating sleeves, making insulating sleeves is to move until sealing ring 1 whole lateral surface 2 on 12 the end face 4 to be close to fully on the inwall of insulating sleeves along gradient.At this moment, sealing ring 1 can be extruded generation deformation, and its inside and outside side 2 can be close on the outer wall of pole or insulating cylinder respectively and on the inwall of insulating sleeves, improve the sealing of whole sealing ring 1 greatly, thereby effectively eliminate the air gap creepage phenomenon.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
