The utility model content
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of dry type plug-type GIS the terminal, and this terminal need not to adopt O-ring seals, has stopped the possibility that sulfur hexafluoride gas leaks, and it is simple in structure in addition, and is easy for installation.
A kind of dry type plug-type GIS terminal of the utility model comprises: contact, touch son, and conductor outlet bar, epoxy resin bushing, stress cone, stress cone holder, tail pipe, said contact is installed in the epoxy resin bushing, and epoxy resin bushing is stretched out in its upper end; Conductor outlet bar is installed in the contact through positioner; Conductor outlet rod outer surface is provided with and is touching son; Conductor outlet rod rear end is provided with patchhole, through patchhole and core crimping mutually, is positioned in the insulation that is placed in cable of stress cone interference of conductor outlet bar lower end; Be enclosed within the stress cone bottom with the stress cone holder of stress cone coupling, the inner surface of stress cone holder contacts with the intimate of stress cone 7 semiconductives part; Epoxy resin bushing is placed in stress cone and the stress cone holder, and the inner surface of epoxy resin bushing contacts with the intimate of stress cone insulated part; Tail pipe is connected with the epoxy resin bushing bottom; Said contact is the integrated contact that closely links together with epoxy resin bushing.
The positioner of above-mentioned conductor outlet bar is: on conductor outlet bar outer rim, laterally be provided with backstay, be provided with the draw-in groove that matches with backstay in the contact.
Be provided with hold down gag between above-mentioned tail pipe and stress cone holder and the epoxy resin bushing; This hold down gag comprises fixed lever, guide rod, spring and ring flange; Several guide rods are fixed on stress cone backing face and the circumferential even distribution in edge; Spring is inserted in each guide rod, and an end and the ring flange of spring lean, and the other end leans the stress cone holder; Said fixed lever one end is connected with epoxy resin bushing, and the other end passes ring flange and links to each other with nut.
The beneficial effect of the utility model: contact and epoxy resin bushing are made as one; Installation steps have been reduced; Simplified installation process; Reduce maintenance workload, and stopped the aging sulfur hexafluoride gas that causes of dry type GIS terminal O-ring seals after having used several years and leak, caused electric property to descend and environmental pollution.In addition, have draw-in groove on the inwall of contact, the backstay of conductor outlet bar is stuck in wherein, and the cable core that conductor outlet bar is connected is difficult in contact, breaking away from.Hold down gag can be given the stress cone increase pressure in addition, improves the contact reliability of stress cone and tapered sleeve.
