Description

A kind of T connector withstand voltage test coupling arrangement
Technical field
The utility model relates to a kind of coupling arrangement doing cable voltage test in cable hut, ring main unit, relates to a kind of T connector withstand voltage test coupling arrangement in particular.
Background technology
Along with the development of urban construction, distribution transformation in city puts more effort, and the application of cable line instead of distribution overhead line in the past gradually.Meanwhile, the widespread use of feeder pillar, ring main unit has expedited the emergence of a large amount of uses of cable terminal equally.In cable line, cable generally adopts T-shaped cable end to be connected to ring main unit and cable hut inlet wire, in cable prevention withstand voltage test in the past, test with cable T connector, more than 96% can cause between testing wire clamp and cable end inwall and discharges, and causes trial voltage to be elevated to setting, therefore, in order to complete test, after having to cable T connector to pull down, formally AC voltage withstand test can be started.But dismounting is unloaded cable end and is taken time and effort so back and forth, and dismounting cable end will affect electric property and the serviceable life of cable end frequently, even damage cable end.
Utility model content
In order to overcome deficiency of the prior art, the utility model discloses a kind of T connector withstand voltage test coupling arrangement, comprising bolt head, conducting rod, sleeve pipe, stepped annular bolt, block head, block head endoporus.Cable termination is plugged on the cable sleeve that is fixed in feeder pillar or ring main unit, and cable sleeve comprises pedestal and is located at the bolt head of pedestal front end, and bolt head can be regular hexagon to play the effect of spacing flange when conducting rod precession.Bolt head is provided with conducting rod, and bolt head and conducting rod can be one-body molded.Conducting rod has external thread, sleeve pipe is apart from hexagon near one end of conducting rod thus enhances the structural strength of sleeve pipe near this side of block head, inside arranges the female endoporus of tool, the other end of sleeve pipe is stepped annular bolt, stepped annular bolt is fixedly connected with block head, preferably both are one-body molded, and on block head, inside has and establishes female block head endoporus.
Cable T connector withstand voltage test coupling arrangement described in the utility model, especially be suitable in cable hut, ring main unit and do cable voltage test, the withstand voltage test of bus and isolating switch, on-load switch in ring main unit, ring main unit inner breaker, on-load switch loop resistance, fundamentally can solve cable and cable machinery in urban distribution network to the test method of commissioning test, preventive trial and the too low problem of efficiency.
Accompanying drawing explanation
Fig. 1 is T connector withstand voltage test coupling arrangement structural representation of the present utility model.
In figure: 1-bolt head 1,2-conducting rod, 3-sleeve pipe, 4-stepped annular bolt, 5-block head, 6-block head endoporus.
Embodiment
Below with reference to the accompanying drawings the utility model is described in detail, wherein figure 1 show structure, and being used as left view and the right view of auxiliary reason formal similarity, the utility model T connector withstand voltage test coupling arrangement comprises bolt head 1, conducting rod 2, sleeve pipe 3, stepped annular bolt 4, block head 5, block head endoporus 6.Cable termination is plugged on the cable sleeve that is fixed in feeder pillar or ring main unit, and cable sleeve comprises pedestal and is located at the bolt head 1 of pedestal front end, and bolt head 1 can be regular hexagon to play the effect of spacing flange when conducting rod precession.Bolt head 1 is provided with conducting rod 2, bolt head 1 and conducting rod 2 can be one-body molded.Conducting rod 2 has external thread, sleeve pipe 3 is regular hexagon near one end of conducting rod 2 thus enhances the structural strength of sleeve pipe near this side of block head, inside arranges the female endoporus of tool, the other end of sleeve pipe 3 is stepped annular bolts 4, stepped annular bolt 4 is fixedly connected with block head 5, preferably both are one-body molded, and on block head 5, inside has and establishes female block head endoporus 6.During construction, first by the cable with cable connecting terminal from feeder pillar, introduce in the entrance hole of ring main unit, the left side port in T connector transverse pipe portion is plugged on the pedestal of cable sleeve, pedestal 11 front end arranges bolt head 1, bolt head 1 to be threaded with sleeve pipe 3 with moving conductive rod 2 and to realize conducting rod 2 and be set in the transverse pipe portion of T connector, block head 5 be plugged in the right side port in transverse pipe portion and offset with stepped annular bolt 4, bolt is screwed into again outside the endoporus of block head 5, the conducting rod of T connector inside is contacted with each other with the outside bolt be screwed into, the test connecting device joint test line be screwed into from outside again.
