Abstract
The utility model relates to a connection device for power equipment in the electrical power system, in particular to a transition connection device for a withstand voltage test of a T-shaped connector position of a cable branch cabinet, which comprises a plurality of connection column bolts connected in sequence. An insulation protection sleeve is sleeved outside the plurality of connection column bolts, and the front portion of the insulation protection sleeve extends out of the front ends of the connection column bolts to form a protection cavity in front of the connection column bolts. The transition connection device is simple in structure, convenient to use, tight in connection, safe and reliable, can successively finish withstand voltage test detection of the cable and the T-shaped connector, and avoids increase of extra maintenance cost caused by the fact that dismounting of the T-shaped connector causes damage of the T-shaped connector.
Description
Technical field:
The utility model relates in a kind of electric power system uses jockey on the power equipment, and the transition jockey is used in the place's withstand voltage test of especially a kind of cable branch box T type connector.
Background technology:
The cable branch box ring main unit is in the distribution line, cable and cable, the vitals that cable is connected with other electric equipments.When distribution line breaks down, also bearing the disengagement failure circuit, set up the important function of power supply looped network.T type connector is the vitals that connects 10kV distribution cable and feeder pillar ring main unit.The silicone rubber sleeve of T type connector is tangible formula connector, and its surface is a layer of semiconductor, directly links to each other with ground.When cable and the connection of T type connector puts into operation preceding or running in cable when breaking down; Need connect test lead at T type connector place carries out withstand voltage test or cable is carried out trouble shoot cable; But because the distance on the junction of test lead and column bolt and silicone rubber sleeve semiconductive layer surface is less than the desired sudden strain of a muscle distance of climbing of test voltage; When applying high pressure; Be prone to cause between junction and the silicone rubber sleeve semiconductive layer surface of test lead and column bolt and discharge,, cause and normally to detect test to T type connector and cable so that can't normally apply test voltage.In order normally to detect to newly put into operation cable and annex or failure cable, need T type connector be disassembled usually, make cable body break away from T type connector, through test lead cable is detected again.After cable detection; Again recovering cable again is connected with T type connector; Operation very bothers like this, and in the process that removes and installs T type connector, stress cone and silicone rubber sleeve that T type connector usually occurs damage; The T type connector that need more renew has again increased the test maintenance cost.
The utility model content:
The utility model provides the place's withstand voltage test of a kind of cable branch box T type connector to use the transition jockey; It is simple in structure, and is easy to use, is connected firmly; Safe and reliable; Can successfully accomplish cable and the withstand voltage test of T type connector and detect, avoid dismounting T type connector to cause T type connector to damage the increase of the additional maintenance cost that causes, solve the problem that exists in the prior art.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises the joint pin bolt that several are linked in sequence; At several joint pin bolt outside suit one insulating sheaths, the front end that the insulating sheath front portion exceeds the joint pin bolt forms a protection chamber in joint pin bolt the place ahead.
The said joint pin bolt that is linked in sequence is two.
Said insulating sheath is double-deck 10kV isolating shrinkable tube.
The utility model is simple in structure, and is easy to use, is connected firmly; Safe and reliable; The column bolt of this transition jockey with T type connector is connected, test lead is connected with this device again, the withstand voltage test that can successfully accomplish cable and T type connector detects; Avoid dismounting T type connector to cause T type connector to damage the increase of the additional maintenance cost that causes, greatly reduced the test maintenance cost.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, the joint pin bolt; 2, insulating sheath; 3, protection chamber.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below through embodiment, and combine its accompanying drawing, the utility model is set forth in detail.
Shown in figure, the utility model comprises two joint pin bolts 1 that are linked in sequence, and at two joint pin bolts, 1 outside suit, one insulating sheath 2, the front end that insulating sheath 2 front portions exceed joint pin bolt 1 forms a protection chamber 3 in joint pin bolt 2 the place aheads.The connecting portion of test lead and joint pin bolt 1 is in the protection chamber 3, can play better insulation effect.
Said insulating sheath 2 is double-deck 10kV isolating shrinkable tube.
When cable and the connection of T type connector puts into operation preceding or running in cable break down; In the time of need connecting that test lead carries out withstand voltage test to cable at T type connector place or cable carried out trouble shoot; The staff takes out test lead, only need pull down protective cover and the insulating plug on the T type connector, and the column bolt of the utility model transition apparatus with T type connector is connected; Again test lead is connected on the joint pin bolt of this transition apparatus; Can increase and climb the sudden strain of a muscle distance between the outer semiconductive layer of test lead and column bolt junction and silicone rubber sleeve, occur electric discharge phenomena when avoiding applying high pressure, guarantee carrying out smoothly of withstand voltage test; Simple and convenient, safe and reliable.Adopt the utility model transition jockey, saved the disassembly process of T type connector, reduced the process of the test time, avoided T type connector ruined situation in the process of removing and installing to take place, greatly reduce the test maintenance cost.
The utility model does not detail part, is those skilled in the art of the present technique's known technology.
Claims (3)
1. the transition jockey is used in the place's withstand voltage test of cable branch box T type connector; It is characterized in that: comprise the joint pin bolt that several are linked in sequence; At several joint pin bolt outside suit one insulating sheaths, the front end that the insulating sheath front portion exceeds the joint pin bolt forms a protection chamber in joint pin bolt the place ahead.
