Abstract
The utility model mainly discloses a wiring board of a GIS switch cabinet. The wiring board comprises an insulating body that is provided with a bulge, a plurality of inserts are embedded in the bulge, and the side wall of each insert is provided with a plurality of grooves. The wiring board is strong in sealing performance, good in shockproof effect and high in compression stress.
Description
Technical field
The utility model relates to patch board device, and is special relevant with a kind of GIS switch cubicle terminal block.
Background technology
The GIS switch cubicle is a kind of gas insulated combined electric appliance equipment, multiple electric equipments such as circuit breaker, isolating switch, earthed switch, voltage transformer, current transformer, lightning arrester, bus, cable termination, turnover thread casing in the transformer station organically are combined into an airtight integral body through optimal design, use gas-insulated, mostly be SF
6Gas.
Because of being full of SF in the GIS switch cubicle
6Gas or other gas-insulateds, whole cupboard require sealing property to get well, and can not leak gas.Therefore, can only draw the secondary line in the cabinet outside the cabinet, use for the secondary device wiring by the terminal block on the GIS switch cubicle.Existing terminal block structure has projection 20 roughly as depicted in figs. 1 and 2 on the insulating body 10, be inlaid with inserts 30 in the projection 20, and wherein insulating body 10 is for poured with epoxy resin forms, but inserts 30 is the brass post of two ends patch terminal.In order to make sealing strong, inserts 30 has a groove 40, improves the compactness that combines of epoxy resin and inserts 30.
There is more problem in the terminal block of this structure in actual use.At first, 3 of inserts have a groove 4, and bolt arrangement is unreasonable, although there is the epoxy resin of raising to combine compactness with inserts 3, compactness is not strong, gas leakage easily, and shockproof effect is poor, causes qualification rate low, and quality can't improve.Secondly, through conscientious research experiment, find that another reason of gas leakage is that inserts 3 is not enough along the face creep distance, gas spills near insulating body 1 from inserts 3 easily.
And GIS switch cubicle terminal block most critical is exactly sealing, so there is fatal defective in traditional structure, the inventor designs a kind of GIS switch cubicle terminal block and overcomes above-mentioned defective, and this case produces thus.
The utility model content
The purpose of this utility model provides a kind of GIS switch cubicle terminal block, and epoxy resin and inlay are combined closely, and sealing is strong, shockproof effect good, stress under compression is high.
To achieve these goals, the technical solution of the utility model is as follows:
GIS switch cubicle terminal block comprises insulating body, has projection on insulating body, is inlaid with several inserts in the projection, offers a plurality of grooves on each inserts sidewall.
Described inserts is a step structure, and from both ends to the middle, radial dimension successively decreases.
On the described insulating body, on the outer ring of projection, be provided with the seal groove of placing for sealing ring.
Described insulating body is an epoxy resin.
Described inserts is the brass post.
After adopting such scheme, inlay of the present utility model is similar to bolt arrangement, and the increase of groove has strengthened the contact surface of epoxy resin and inserts, and adhesion is mentioned reinforcement.
In addition, the inserts two ends form stepped, improve along the face creep distance, further improve the dynamics that combines of epoxy resin and inlay.Simultaneously inserts from both ends to the middle, radial dimension successively decreases, thus the external diameter of groove also the diameter than inlay end is little, thickeied the thickness of epoxy resin between the adjacent inserts like this, compression stress increases, and combines with the inserts of bolt shape is better.
Description of drawings
Fig. 1 is existing terminal block structure chart;
Fig. 2 is that existing terminal block A-A is to cutaway view;
Fig. 3 is the cutaway view of the utility model preferred embodiment.
Embodiment
The overall outer structure of the preferable enforcement of the utility model is same as shown in Figure 1, comprises insulating body 1, has projection 2 on insulating body 1, is inlaid with several inserts 3 in the projection 2, and the material of insulating body 1 is an epoxy resin, and inserts 3 is the brass post.The utility model and traditional wired plate difference are its internal structure.
As shown in Figure 3, GIS switch cubicle terminal block offers a plurality of grooves 4 on each inserts 3 sidewall, be similar to bolt arrangement.Like this, the contact area between inserts 3 and the insulating body 1 increases considerably, and both are in conjunction with tightr.
In addition, insulating body 1 is provided with seal groove 5 on the outer ring of projection 2, places sealing ring during use in the seal groove 5, utilizes sealing ring can make insulating body 1 and the further effectively sealing of GIS switch cubicle, prevents gas leakage.
Bolt arrangement is reasonable in the utility model inserts 3, and inserts 3 increases greatly with effective contact-making surface of epoxy resin, improves compactness and shake-proof ability.3 two ends of inserts are step structure, strengthen along the face creep distance, in conjunction with tight.
The foregoing description is used to explain inventive concept of the present utility model, but not to the qualification of the utility model protection range, if change based on any unsubstantiality under the utility model design, all should fall among the protection category of the present utility model.
