Reference numeral: insulator 1, high-tension electricity introduce terminal 2, high-tension electricity leading-out terminal 3, conduction connecting screw rod 4, the passage 5 that is threaded, insulation blanket stud 6, insulation end socket 7, insulated tube 8.
Embodiment
The utility model has insulator 1 as can be seen from Figure 2, high-tension electricity introduces terminal 2, high-tension electricity leading-out terminal 3, conduction connecting screw rod 4, be threaded passage 5, high-tension electricity introduces terminal 2 and high-tension electricity leading-out terminal 3 is fixed in insulator 1, the passage 5 that is threaded is provided with in insulator 1, this passage that is threaded runs through high-tension electricity introduces terminal 2 and high-tension electricity leading-out terminal 3, conduction connecting screw rod 4 matches with the passage 5 that is threaded, make high-tension electricity introduce terminal 2 by this interface channel to be connected with high-tension electricity leading-out terminal 3, high-tension electricity leading-out terminal 3 again with cable branch box, ring main unit or high voltage load switch connect, the electricity of electrical network delivers to cable branch box by high-tension electricity leading-out terminal the most at last, ring main unit or this kind equipment of high voltage load switch, load is made to obtain electric and run.Before conduction connecting screw rod 4 connects or disconnects high-tension electricity introduction terminal 2 and high-tension electricity leading-out terminal 3, preferably prepare an insulated tube 8, be arranged on and be threaded on the port of passage 5, conduction connecting screw rod 4 enters or exits from insulated tube 8 passage 5 that is threaded, make high-tension electricity introduce terminal 2 be communicated with high-tension electricity leading-out terminal 3 or disconnect, prevent the exposed part electric discharge of conduction connecting screw rod from hurting sb.'s feelings.
Conduction connecting screw rod 4 removes insulated tube 8 again after completing connection or disconnection task.The passage 5 that is threaded preferably adopts through hole, and the other end of the passage 5 that is threaded can arrange insulation end socket 7, under normal circumstances a shutoff, only opens when checking or clear up and be threaded passage 5.
High-tension electricity is introduced between terminal 2 and high-tension electricity leading-out terminal 3 will enough distances, an insulation blanket stud 6 is preferably prepared during maintenance, after taking-up conduction connecting screw rod 4, enter on insulation blanket stud 6, make high-tension electricity introduce terminal 2 to be insulated by insulation blanket stud 6 with the passage 5 that is threaded between high-tension electricity leading-out terminal 3, otherwise air insulation can increase the distance between described two-terminal, the bulk of whole device is strengthened, and insulation effect is bad.Introduce between terminal 2 and high-tension electricity leading-out terminal 3 with insulation blanket stud 6 pairs of high-tension electricities and insulate, can guarantee that this kind equipment of the cable branch box of Awaiting Overhaul, ring main unit or high voltage load switch is no longer charged, so that safety inspection.
What insulator adopted in the present embodiment is cube, makes have between each component the most reasonably to arrange, can certainly adopt other shapes.The head (with connecting position of wires) of high-tension electricity introduction terminal 2 and high-tension electricity leading-out terminal 3 is arranged in the opposition two sides of upper described insulator, to ensure interval therebetween.
Fig. 3 reflects using state of the present utility model.Six travel permit branch roads are had as can be seen from Figure 3 under electrical network A, each branch road is all equipped with the utility model C, installation site is between electrical network A and cable branch box or ring main unit or high voltage load switch B, the high-tension electricity of the utility model C is introduced terminal 2 and is connected with electrical network A, and high-tension electricity leading-out terminal 3 is connected with cable branch box, ring main unit or high voltage load switch B.We can select any branch road, under normal operation, high-tension electricity is introduced terminal 2 and is connected by conducting electricity connecting screw rod 4 with between high-tension electricity leading-out terminal 3, the electricity of electrical network A is delivered to cable branch box, ring main unit or high voltage load switch B, when the cable branch box of this branch road, when ring main unit or high voltage load switch B need to overhaul, to the utility model device on this branch road, take off its conduction connecting screw rod 4, enter on insulation blanket stud 6 again, the now cable branch box of this branch road, ring main unit or high voltage load switch B no longer charged, just can to this cable branch box, ring main unit or high voltage load switch carry out having overhauled.Here can find out and not need to implement to have a power failure to electrical network A, because electrical network other branch roads that do not have a power failure still normally run, not be affected.So ensure that other tributary user no longer follows power failure, both ensure that the interests of user also effectively improve the economic benefit of power supply department.
