Abstract
The present utility model relates to the electric power transmission and transformation equipment field, concretely to a high voltage breaker contact assembling tool. The tool comprises a fastening piece and a positioning piece, four holes are uniformly distributed on the side wall of a high voltage contact, the fastening piece is a steel pipe with one end enclosed, the upper end face of the steel pipe is provided with a sealing plate, and the upper part of the sealing plate is fixedly connected with a hexagonal steel. The side wall of the steel pipe is provided with four holes, the diameter of each hole is the same as that of each hole on the side wall of the contact, the position of the holes on the side wall of the steel pipe is corresponding with the position of the holes on the side wall of the contact, the positioning piece is a cylinder, and the external diameter of the positioning piece is matched with the fastening piece and the holes on the side wall of the contact. By adopting the tool, the assembling of the high voltage breaker contact is firm and reliable, and the service life of a breaker can be increased.
Description
Technical field
The utility model relates to the power transmission and transforming equipment field, a kind of primary cut-out contact assembly tool.
Background technology
The contact of circuit breaker is main conductive component, when assembling, requires the conducting surface contact reliable, and is as much as possible little to guarantee contact resistance.Contact of breaker generally adopts screw connection structure; Be that contact itself has external screw thread or internal thread; Be connected cooperation with the touch base of aluminium material; But contact is generally round tubular structure, does not have the corresponding specific purpose tool can't be fastening reliably, and can not reliable detection goes out Tightening moment and whether reach requirement.If fail reliably fasteningly, when breaker operator, take place looseningly will cause resistance to exceed standard, when load current during bigger or through-flow short circuit current, can a large amount of heatings even melt in the position of loose contact, has a strong impact on the performance of circuit breaker.
Summary of the invention
The purpose of the utility model is a kind ofly can contact of breaker be installed fastening primary cut-out contact assembly tool.
The technical scheme of the utility model is: a kind of primary cut-out contact assembly tool; Comprise securing member and keeper; Four holes that on the sidewall of primary cut-out contact, are uniformly distributed with; It is characterized in that: described securing member is the steel pipe of end sealing, and the upper surface of described steel pipe is provided with shrouding, and described shrouding top is fixedly connected with hexagonal steel; The sidewall of described steel pipe is provided with four holes that the hole on the side arm of diameter and contact equates, the position in hole is corresponding with the hole site on the contact sidewall, and described keeper is the cylinder that external diameter matches with securing member and contact areole.
The utility model has also designed described shrouding top and has offered the hole of being convenient to observe.
It is steel material that the utility model has also designed described shrouding.
It is to be processed by carbon steel material that the utility model has also designed described keeper.
Be enclosed within securing member on the contact during use; And be through keeper the tapping of securing member and contact; Hexagonal steel with on torque spanner or the fork spanner constraint securing member is realized tightening or loosening getting final product, and adopts torque spanner can also check Tightening moment and whether can reach requirement.
The beneficial effect of the utility model is: the utility model has been realized the reliably fastening of primary cut-out contact, in the useful life of having improved circuit breaker, has good value for applications.
Description of drawings
Fig. 1 is a kind of primary cut-out contact of the utility model assembly tool structural representation.
Embodiment
A kind of primary cut-out contact assembly tool; Comprise securing member 1 and keeper 2; Four holes 4 that on the sidewall of primary cut-out contact 3, are uniformly distributed with; Described securing member 1 is the steel pipe of end sealing, and the upper surface of described steel pipe is provided with shrouding 6, and described shrouding 6 tops are fixedly connected with hexagonal steel 7; The sidewall of described steel pipe is provided with four holes that the hole on the side arm of diameter and contact equates, the position in hole is corresponding with the hole site on the contact sidewall, and described keeper 2 is cylinders that external diameter matches with securing member 1 and contact areole.
The utility model has also designed described shrouding 6 tops and has offered the hole of being convenient to observe 9.
The utility model has also designed described shrouding 6 and has been steel material.
It is to be processed by carbon steel material that the utility model has also designed described keeper 2.
Be enclosed within securing member 1 on the contact during use; And be through the tapping of securing member 1 and contact to keeper 2, and to realize tightening or loosening get final product with the hexagonal steel on torque spanner or the fork spanner constraint securing member, the employing torque spanner can also be checked Tightening moment and whether can be reached requirement; Four holes of the processing that on the sidewall of contact, is uniformly distributed with; Diameter can calculate according to the Tightening moment of contact screw thread, can be processed into through hole as sidewall is thin, and wall thickness surpasses 15mm then can process the dark blind hole of 10mm.
The beneficial effect of the utility model is: the utility model has been realized the reliably fastening of primary cut-out contact, in the useful life of having improved circuit breaker, has good value for applications.
