Abstract

The utility model relates to the field of power equipment. The utility model provides a female structure of arranging of new stromatolite to improve the female creepage distance who arranges between the conductive contact of stromatolite. The utility model provides a following technical scheme: a female structure of arranging of stromatolite that application connects, the stromatolite is female to be arranged includes a plurality of conductive layers and multilayered insulating layer, a plurality of conductive layers is last to install a plurality of conductive contacts, the conductive contact surface is scribbled and is equipped with insulating coating. The utility model discloses an at the side of conductive contact application insulating material, simultaneously the conductive contact the height for the big play of interval between the conductive contact many, consequently, through insulating material's application, improved the creepage distance between adjacent conductive contact a lot, effectively improved the female row's of stromatolite electric property. The utility model discloses use the epoxy powder to carry out the application, epoxy have insulating properties good, high temperature resistant, adhere to advantage such as reinforce to the female row of high -performance stromatolite brings.

Description

A kind of laminated bus bar structure applying joint

Technical field

This utility model is related to field of electrical equipment, particularly a kind of laminated bus bar structure being provided with painting joint.

Background technology

Stack bus bar is that to have repeatable electric property, Low ESR, anti-interference, good reliability, save space, assembling succinct The high-power modular attachment structure part of quick the features such as, is now widely used in power domain.Stack bus bar produces in design One of process important parameter is exactly creep age distance.The size of creep age distance directly affects the performance of stack bus bar.And fold , therefore there is certain limit to structure and space in the design of layer busbar and produce and typically require demand according to user to customize System.How in the structure limiting and space, to design larger creep age distance, be of stack bus bar field needs solution Major issue.

As shown in accompanying drawing 4,5,6, using common conductive contact on stack bus bar, do not make any technological improvement, its , as shown in the creep age distance 41 in accompanying drawing 6, creep age distance is relatively small for creep age distance.As shown in accompanying drawing 7,8,9, lead in adjacent Creep age distance after insulation tank is installed between electric connection as shown in the creep age distance 42 in accompanying drawing 9, in the base of non-structural improvement Certain lifting is had on plinth.But this improvement project uses the installation reliability of insulant relatively low, less stable, simultaneously Increased the production process of stack bus bar, overall utility is poor.

Utility model content

The purpose of this utility model is to provide a kind of new laminated bus bar structure, to improve between stack bus bar conductive contact Creep age distance.This utility model provides technical scheme below：

A kind of laminated bus bar structure applying joint, stack bus bar includes plurality of conductive layers and multilayer dielectric layer, multilamellar Multiple conductive contacts are provided with conductive layer, described conductive contact outer surface is coated with insulating coating.

As a kind of preferred version of the present utility model, the insulating coating of described conductive contact outer surface is epoxy resin powder End.

As another kind preferred version of the present utility model, described conductive contact is cylindric, and insulating coating is coated on institute State the side of conductive contact.

This utility model advantage is：

This utility model passes through the side application insulant in conductive contact, and the height of conductive contact is with respect to leading simultaneously Spacing between electric connection goes out greatly many, therefore, by the application of insulant, the creep age distance between adjacent conductive joint is improved A lot, effectively increase the electric property of stack bus bar.

This utility model carries out application using epoxy powder, and epoxy resin has good insulation preformance, high temperature resistant, adhesive force Strong the advantages of, thus bring high performance stack bus bar.

Specific embodiment

Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model Can be easier to be readily appreciated by one skilled in the art with feature, thus make apparent clear and definite to protection domain of the present utility model Define.

As shown in accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, this utility model stack bus bar includes positive plate 1 and negative plate 2, positive pole Positive plate conductive contact 11 is provided with plate 1, negative plate 2 is provided with negative plate conductive contact 21, positive plate conductive contact 11 It is coated with insulating coating 3 with the side of negative plate conductive contact 21, in the present embodiment, insulating coating 3 is epoxy powder.

As shown in Figure 3, in figure dotted line is creep age distance 4, compared to the creep age distance 41 in accompanying drawing 6, this creep age distance Value improves more than 100%.

The above, specific embodiment only of the present utility model, but protection domain of the present utility model does not limit to In this, in technical scope disclosed by this utility model for any those of ordinary skill in the art, can be without creative labor The dynamic change or replacement expected, all should cover within protection domain of the present utility model.Therefore, protection model of the present utility model Enclose and be defined by the protection domain that claims are limited.
