Abstract
The utility model discloses a grounding static contact used for an inflation cabinet. The grounding static contact used for the inflation cabinet comprises a mounting plate and a contact head, wherein a lower portion of the mounting plate is provided with mounting through-holes, and the contact head is arranged at one side edge of a top portion of the mounting plate and is perpendicular to the mounting plate. The grounding static contact used for the inflation cabinet has properties of simple structure, good quality and relatively low cost and facilitates application and popularization of the inflation cabinet.
Description
Technical field
The utility model relates to the inflation cabinet, relates in particular to a kind of ground connection fixed contact for the inflation cabinet.
Background technology
The inflation cabinet be a kind of be one with on-load switch, isolating switch, earthed switch, be sealed in the casing that is full of insulating gas, utilize insulation, the arc extinction performance of sulphur hexafluoride (SF6) gas excellence, close satisfied pass, the switchgear of isolation, ground connection three station functions.Simple in structure, advantages such as interlocking is reliable, volume is little, the easy installation of safety that this inflation cabinet has can be widely used in different application scenarios, and market prospects are fine, and development in recent years is at full speed.
The ground connection fixed contact is the necessary parts of inflation cabinet, and it is corresponding with three phase lines, and every unit is joined three.Existing ground connection fixed contact shape and structure more complicated, need special mould, and then water casting copper alloys, die cost is very high, has increased cost, and because complex-shaped, the requirement of product quality is difficult to reach very, maintenance cost is also very high, will cause fracture in case run into inner trachoma or other defect, produces major accident.
The utility model content
The purpose of this utility model is to solve above-mentioned problems of the prior art, proposes a kind of ground connection fixed contact for the inflation cabinet.
The ground connection fixed contact that is used for the inflation cabinet that the utility model proposes comprises: a bottom is provided with mounting panel that through hole is installed, is located at described mounting panel top one side and a perpendicular contact.
In one embodiment, pass one with contacted two corresponding surfaces of moving contact bottom on the described contact and prevented the position pin, carry out chamfered with the contacted side of moving contact on the contact.
Described ground connection fixed contact adopts the bronze medal integral production.
The utility model is simple in structure, and handling ease only needs pressing and bending technology to get final product, and adopts common bronze medal commonly used as material, and intensity is good, and buying easily, and the duration is short.Because the bronze medal raw material is to adopt batch production technique to make, steady quality is evenly inner, can not produce distortion and fracture damage, makes whole cost greatly reduce, and is approximately 50% of original casting copper contact, is easy to promote the use of.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is left view of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1 and Figure 2, the ground connection fixed contact that is used for the inflation cabinet that the utility model one embodiment proposes, comprise that a bottom is provided with the mounting panel 1 that through hole is installed, mounting panel top one side is provided with a perpendicular contact 2, mounting panel utilizes screw to pass through hole 4 is installed, and add lock washer, the fastening correct position that is installed on the fixed head.Adopted bigger planar design with moving contact 5 contacted two corresponding surfaces on the contact, so the pressure divergence of moving contact incision can not influence good the contact with the moving line deviation, thereby can guarantee better that contact resistance reaches minimum.And this two corresponding surfaces bottom is passed one and was prevented position pin 3, and this prevented that the position locks to install and join, and prevents that moving contact from crossing the position when incision, carries out chamfered with the contacted side of moving contact on the contact, reduces friction.
Manufacture craft of the present utility model is very simple, can adopt the bronze medal integral production.Add man-hour, earlier the width of rectangular standard bronze medal according to mounting panel and contact cut off, form a square, stamp out a block breach for one jiao from the square bottom again, form orthogonal two faces in the same plane, then two faces are bent mutually 90 degree and get final product.Just in time can utilize the circular arc limit of original bronze medal on the contact with the smooth circular arc chamfering of the contacted side of moving contact, be conducive to the incision of moving contact more and reduce wear life-saving.
Only in order to illustrate structure of the present utility model, those of ordinary skill in the art can make various deformation and variation to above specific embodiment under design of the present utility model, and these distortion and variation include within protection range of the present utility model.
Claims (4)
