Abstract
The utility model relates to an extra-high voltage insulation voltage-sharing ball which comprises voltage-sharing balls and insulation cylinders sleeved on two ends of each voltage-sharing ball. The inner wall of each insulation cylinder is provided with insulation blocks contacted with the voltage-sharing balls, and guide grooves for guiding of the insulation blocks are arranged on the inner wall of each insulation cylinder corresponding to the insulation blocks in position. Springs are arranged in the guide grooves, wherein one end of each spring is fixed on each insulation cylinder, and the other end of each spring is connected with each insulation block. According to the extra-high voltage insulation voltage-sharing ball, the insulation blocks are movably arranged on the inner wall of each insulation cylinder and guided by the guide grooves, due to the fact that the function of the springs enables positions of the insulation blocks to be changed in different using environment, good contact of the insulation blocks and the voltage-sharing balls can be achieved, and electric field distribution around the voltage-sharing balls can be guaranteed.
Description
Technical field
The utility model relates to a kind of ultra high voltage insulation voltage equalizing ball, belongs to transformer part.
Background technology
Along with improving constantly of transformer manufacturing technology and insulating material quality, it is more and more littler that the insulation distance in the transformer designs, and therefore makes transformer internal structure space more and more littler; But sleeve pipe in the extra-high voltage transformer high-pressure side; Since to voltage equalizing ball over the ground between required distance bigger, so bring big difficultly to design, the patent No. is 032273142 a kind of voltage equalizing ball insulation system to be provided for this reason; It can form a small oil gap around voltage equalizing ball; Thereby effectively improve the Electric Field Distribution around the voltage equalizing ball, reduce voltage equalizing ball over the ground between distance, for structural design is brought bigger convenience.
But there is defective in above-mentioned patent; Owing to some collets that contact with voltage equalizing ball are set at the insulating cylinder inwall; Owing to make the error with fit on, be difficult to guarantee that each collets and voltage equalizing ball all can contact good the contact, like this to voltage equalizing ball on every side Electric Field Distribution bring and have a strong impact on.
The utility model content
The utility model is to above-mentioned defective, and purpose is to provide a kind of collets and voltage equalizing ball of making to form the good ultra high voltage insulation voltage equalizing ball that contacts.
The technical scheme of the utility model employing is for this reason: the utility model comprises voltage equalizing ball and the insulating cylinder that is set in the voltage equalizing ball two ends; The insulating cylinder inwall is provided with the collets that contact with voltage equalizing ball; The corresponding collets of said insulating cylinder inwall position is provided with the gathering sill of guiding collets, is provided with in the gathering sill that an end is fixed on the insulating cylinder, the other end is connected the spring on the collets.
The utility model has the advantages that: the collets of the utility model are movably arranged on the insulating cylinder inwall; And lead by gathering sill; And because the effect of spring makes it can the position of collets changed; Make it all can form good the contact, guarantee voltage equalizing ball Electric Field Distribution on every side with voltage equalizing ball.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of insulating cylinder.
1 is that voltage equalizing ball, 2 is that insulating cylinder, 3 is that gathering sill, 4 is that collets, 5 are spring among the figure.
Embodiment
The utility model comprises voltage equalizing ball 1 and the insulating cylinder 2 that is set in voltage equalizing ball 1 two ends; Insulating cylinder 2 inwalls are provided with the collets 4 that contact with voltage equalizing ball 1; The corresponding collets of insulating cylinder 2 inwalls 4 positions are provided with the gathering sill 3 of guiding collets 4, are provided with in the gathering sill 3 that an end is fixed on the insulating cylinder 2, the other end is connected the spring 5 on the collets 4.
When the utility model uses; When insulating cylinder 2 is set on the voltage equalizing ball 1, collets 4 travel forward under the effect of spring 5 or motion backward, make its ability and voltage equalizing ball 1 form excellent contact; Because the effect of gathering sill 3 makes it that situation such as deflection can not take place in motion process.
