Abstract
The utility model relates to a cable connecting device for a voltage transformer, and the device comprises a voltage transformer plug seat, a silicon rubber cable plug connected with a cable, and a fastening piece for clamping the voltage transformer plug seat and the silicon rubber cable plug. The cable plug is divided into two structures of a straight plug and an elbow plug which are fitted with the voltage transformer plug seat, respectively suitable for the connection of the incoming wire and the outgoing wire of different forms voltage transformers. The design of the structure is reasonable, an electric conductor is enclosed in epoxy resin and silicon rubber, the problems of conductor insulation, pollution flashover, moist discharging and shelf depreciation of the traditional product are resolved, the utility model is high temperature resistant and anti-ultraviolet, and the service life can be attained over 20 years. The generalization of the utility model is beneficial to realize the full isolation, the full hermetic closure, the full guard and the reduction of the volume of a box-type voltage transformer.
Description
The utility model relates to the jockey of transformer turnover line, particularly a kind of silicon rubber plug on cable jockey that is used for transformer.
China's power distribution net is based on overhead transmission line always for many years.Therefore the distribution transformer in city, suburb or rural area all is the connected mode that adopts outlet porcelain vase one wire clamp, one aluminum conductor or aluminium steel conductor.This wire conductors exposes, and has problems such as pollution flashover, moist discharge and partial discharge, usually causes the shorted to earth accident owing to climb up toy on the lead.
Along with urban network restructuring and city net cableization, the incompatible requirement that increases substantially reliability of old outlet porcelain vase one wire clamp one aluminum conductor connected mode, as reduce or eliminate accident, prolong time between overhauls(TBO), particularly interruption maintenance cycle etc.In order to protect contact; prevent that filth, eliminating toy from causing ground short circuit, solving moisture effect and personal safety problem; at present many power supply administrations adopt distribution transforming contact protection box, and this measure to a certain extent can the minimizing accident, but still can not fundamentally address the above problem.
West advanced country just begins to adopt new transformer cable connected mode as far back as the mid-80, promptly adopts the connected mode of the epoxy resin pedestal rubber plug of vacuum pouring.
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of cable connecting arrangement that is used for transformer is provided, to satisfy the needs of modernized power network development.
This cable connecting arrangement comprises: be connected in transformer socket, the cable plug of transformer and the securing member that compresses both, described cable plug is made up of the silicon rubber plug boot of plug terminal and plug terminal outside.
Description of drawings of the present utility model is as follows:
Fig. 1 is straight type cable connecting arrangement structure chart;
Fig. 2 is straight type cable connecting arrangement exploded view;
Fig. 3 is its elbow type cable connecting arrangement structure chart;
Fig. 4 is its elbow type cable connecting arrangement exploded view.
Fig. 1,2 is depicted as its exemplary embodiments structure chart.Its cable connecting arrangement comprises: the straight shape plug boot 1 of silicon rubber, be arranged at semi-conductive tape 4 between plug boot 1 afterbody and the cable, transformer socket 5, connecting bolt 6, fixedly straight shape plug terminal (moving contact) 8, clamp nut 9 and the shielding earth 10 etc. of flange disc 7, stube cable 3.The straight shape plug boot 1 of straight shape plug terminal 8, silicon rubber and the clamp nut 9 that wherein are crimped on cut cable are formed cable plug, and plug terminal 8 inserts in the straight shape plug boot 1 of silicon rubber, and is fixing by nut 9.Cable plug is with after the transformer socket is connected, by ring flange 7 and bolt 6 fastening jails.
Fig. 3,4 is depicted as its another example structure figure.This cable connecting arrangement comprises: transformer socket 5 ', connecting bolt 6 ', fixedly cable ear 2 ', semi-conductive tape 4 ' and the shielding earth 10 ' etc. of flange disc 7 ', plug terminal (moving contact) 8 ', silicon rubber elbow plug boot 1 ', stube cable 3 '.Wherein the cable ear 2 ' of plug terminal 8 ', stube cable and silicon rubber elbow plug boot 1 ' are formed cable plug.Cable ear 2 ' end has the connecting thread hole, be positioned at silicon rubber elbow plug boot 1 ' crosspiece plug terminal 8 ' and place perpendicular section cable ear 2 ' of rubber elbow plug boot 1 ' by being threaded.Cable plug is with after the transformer socket is connected, by ring flange 7 ' and bolt 6 ' fastening jail.
The utility model adopts new material silicon rubber (SR), enables development new type silicone rubber attachment plug of automatic pressure gel (APG) new technology and neo-epoxy resin socket, for distribution transformer provides a kind of new cable connected mode.The straight shape plug boot of its silicon rubber elbow plug boot and silicon rubber adopts the manufacturings of silicon rubber material and APG new technology, and silicone rubber jacket has following superiority than General Purpose Rubber sheath:
1 has hydrophobicity, has both made rainfall also can not as for reduction moist, that frost mist does not influence its insulation property naturally, make the creepage distance increase many at the continuous globule of silicone rubber jacket surface detention.
2 is anti-filthy good, the dunghill that both made silicone rubber jacket surface deposition, and these pollution layers encircle because of O-Si is arranged, and cause pollution layer that hydrophobicity is also arranged, thereby pollution flashover accident is significantly reduced.Salt mist test in same concentration proves that silicon rubber tolerance creep distance has increased 30% than porcelain vase.
3 is high temperature resistant, uvioresistant, and can reach more than 20 years useful life.
The employing of automatic pressure gel (APG) technology makes its mechanical strength big, and structure is closely knit, and size is accurate, and its stress is cast big by 10～20% than vacuum.Good electric property, for example the CT of vacuum casting epoxy resin (current transformer) apply 7kV just generation office put, APG then makes the office of product put and bring up to more than the 10kV.
Energized conductor in the jockey is not exposed to air, but be packaged among epoxy resin and the silicon rubber, solved the following point that traditional product exists preferably: (1) conductor insulation problem, (2) pollution flashover problem, (3) moist discharge problem, (4) partial discharge problem, (5) climb up the problems such as shorted to earth of toy.
According to processing electric-field intensity distribution experience for many years, carried out optimal design on its structure, the direct connection of cable and the electric-field intensity distribution problem in the knuckle joint dual mode have been solved, take outside effective silicon rubber conductive layer (Outer conducting Inner) and the hermetically-sealed cable tail end, particularly take necessary conductive layer to arrange elbow type joint to straight type joint.
Promoting the use of of this cable connector helps realizing all insulation, totally-enclosed, the full protection of transformer.Be used for box type transformer and can strengthen insulation margin, reduce the casing volume, meet electric power system miniaturization, the excellent technological trend of insulation.
