Description
Technical field: the utility model relates to the transition joint annex shaped device of high pressure, ultra-high voltage cross-linking polyethylene-insulated power cable, is specially 66KV, 110KV, 220KV, 330KV and 500KV cross-linked polyethylene insulated cable transition joint welding annex shaped device.
Background technology: countries in the world are all used high-pressure cross-linking cable in a large number now, and each manufacturer also strengthens crosslinked cable material, technology, design and annex research are satisfied user's needs.Not only in Japan, in Europe and the North America all begun or prepared to use in a large number ultra-high voltage cross-linking cable, Korea S, Australia is all report development ultra-high voltage cross-linking cable and annex also.But the annex research work always lags behind cable research, often at first is used for short section because new cable is used, and just can uses annex in a large number to big length transmission line of electricity.China's high pressure, the research of ultra-high voltage cross-linking cable annex lag behind cable especially.Existing 12 the upright towers of China can be produced 220kV and above crosslinked cable ability at present, the 220kV crosslinked cable that the production of 4 tame factories is arranged is by technical appraisement, but the annex exploitation only rests on the 110kV level, and what domestic high-pressure cross-linking cable annex can provide delivery only is the ancient cable factory in three former companies and Shen.And super-pressure 500KV crosslinked cable transition joint annex is not developed the technology of moulding at home, is very few abroad yet.Current China urban network reconstruction promotes big length high-pressure cross-linking cable line applications, and annex has become the bottle neck of many homemade cable application, therefore notices that the technology of domestic and international crosslinked cable is dynamic, and the homemade annex of active development becomes urgent problem.
At first, the high-voltage cross-linking polythene cable joint adopts the wrapped method of self-adhesive tape, and its shortcoming is that the gap between the belt causes electrical breakdown easily; The wrapped heating method of molding of the crosslinkable polyethylene belt of employing of the eighties exploitation, but the polyethylene belt is easy to dust suction, impurity is brought in the connector, easily causes defective, and bubble also is difficult to avoid in the joint; Countries in the world are adopted the integral prefabricated joints of big hole enlargement compacts more at present; after connected cable handling is good; on-the-spot hole enlargement; the prefabricated component hole enlargement to surpassing the cable cover(ing) diameter, is enclosed within on any one section cable, conductor is carried out crimping; in the middle of then prefabricated component being moved to; take out the hole enlargement cover, adjust prefabricated component, handle insulation external shield and protecting sheathing and promptly finish the joint action to assigned position.It is neat inadequately that this joint inevitably makes the semi-conductive layer fracture handle, and the slope is uniform and smooth inadequately, and the semi-conductive adhesive of coating and the body of cable may not necessarily be tightened to one, is difficult to the control semiconductive particles and is not brought in the insulating joint; The convergent divergent channel of prefabricated expansion has a wedge angle slightly or has protruding particulate, will be with the joint squeeze crack when expansion; The length that cable jacket was broken when preparation joint was made does not reach the sealing and the mechanical level of cable body than long one times of other form joint when recovering, and after preparation joint completes, inflexibility and arbitrarily mobile.Japan at first is devoted to exploration can better the die casting connector, after 1989 first time long transmission line begins to use the die casting connector, up to middle nineteen nineties, this joint has occupied leading position in this stage, uses nearly more than 1000 this joints in the circuit.But fabrication cycle is long, and Japan's 3 joints in report one loop need be made one month, and the time is long, efficient is low, the wasting manpower and material resources, is difficult to apply.There is not to find to have an identical similar patent application through Patent Office of the People's Republic of China's CD query and search home and overseas with the utility model.
Summary of the invention: the purpose of this utility model is to provide a kind of following power cable with cross-linked polyethylene insulation transition joint of 500KV simple, with low cost, that running quality is stable, safe and reliable, easy to use welding shaped device of constructing.The purpose of this utility model is achieved in that it comprises moulding body (1), poly-tetrafluoro (2), fastening terminal (3), electric calorifie installation (4), cooling cavity (5), guide way (6), glue-feeder (7), water filling port (8), head (9), Jiao Dao (10), slit (11), silicane rubber plate (12), cavity (13), groove (14); The utility model is made of moulding body (1), guide way (6) and head (9) three parts, moulding body (1) one end is connected with guide way (6), the other end is connected with guide way (6) through head (9), between moulding body (1) and the silicane rubber plate (12) slit (11) is arranged, glue-feeder (7), Jiao Dao (10) are arranged on the head (9), be poly-tetrafluoro (2) between guide way (6) and the cavity (13).Moulding body (1) is circular, is connected with fastening terminal (3) at the outer surface of moulding body (1), is fixedly connected with electric calorifie installation (4) by screw on moulding body (1) outline body.Glue-feeder (7) is communicated with Jiao Dao (10).Water filling port (8) and cooling cavity (5) are arranged on the guide way (6), and water filling port (8) is communicated with cooling cavity (5).Silicane rubber plate (12) is to be wrapped on head (9) and the cable body.The utility model has the advantages that: simple, with low cost, the advanced technology of constructing, running quality are more stable, safe and reliable, easy to use, the utility model Production Time weak point, adapt to the urgent need installation of voltage levels cable work, cable accessory and the demand of breakdown repair, the field fabrication installation period is installed also short than prefabricated joint, be applicable to that the connecting hose of submarine cable is installed.
