Abstract

The utility model discloses a kind of connector for electric power lightning protection overvoltage protector; top board stage casing has deep-slotted chip breaker; lower platen stage casing has arc lower groove, and described upper deep-slotted chip breaker and arc lower groove are oppositely arranged formation one cavity, and described top board is connected respectively with two ends, lower platen left and right.The connector that the utility model provides is when the connection of lightning protection overvoltage protector and cable, and can not suffer damage cable, thus ensure that the normal electric property of power transmission cable.

Description

A kind of connector for electric power lightning protection overvoltage protector
Technical field
The utility model relates to electric power safety and protection field, is specifically related to a kind of connector of electric power lightning protection overvoltage protector.
Background technology
Cable, as the important component part of electric power system, as the carrier of power delivery, plays very important effect in power transmission and distribution process.From the viewpoint of load, cable can be roughly divided into type low-voltage cable, high voltage cable and superhigh pressure cable; Also bare wire and insulated electric conductor can be divided into from cable outer layer with or without insulation protection aspect.
In electric power system transmission line, for reaching maximise transmission efficiency, remote distance power transmission is normal adopts high pressure and even ultrahigh voltage power transmission means; In field, wilderness, due to the restriction of geographical environment, transmission line many employings overhead transmission line; In addition, transmission line adopts brandreth aerial cable to carry out high-voltage transmission especially in order to avoid people and animals come to harm.On whole electric line, lightning-caused breaking is a general difficult problem, and especially in remote power transmission line, power circuit breaks, insulator arc-over can cause large-area power-cuts, thus bring the loss of electricity sales amount and great personal injury, and along with huge economic loss.Therefore, lightning protection overvoltage protection just seems particularly important.
When existing lightning protection overvoltage protector is connected with the termination of cable contact, connection end easily by loose for cable pressure, thus affects the electric property of cable and the electric power transfer of transmission system.
Utility model content
When the utility model is connected with cable for solving lightning protection overvoltage protector, the problem that cable is easily damaged, provides a kind of lightning protection overvoltage protector connector of improvement.
Concrete scheme of the present utility model is as follows:
For a connector for electric power lightning protection overvoltage protector, top board stage casing has deep-slotted chip breaker, and lower platen stage casing has arc lower groove, and described upper deep-slotted chip breaker and arc lower groove are oppositely arranged formation one cavity, and described top board is connected respectively with two ends, lower platen left and right.
As improvement, be also provided with cushion pad and lower cushion pad, described upper cushion pad is placed in deep-slotted chip breaker, and described lower cushion pad is placed in arc lower groove.
As improvement, the width of described top board and lower platen is 10cm to 20cm.
As improvement, one end of described top board and lower platen is gemel connection, and the other end is that bolt connects.
As improvement, described top board and lower platen two ends are all that bolt is connected.
The beneficial effects of the utility model are: when lightning protection overvoltage protector is connected with cable, cable can not suffer damage, thus ensure that the normal electric property of power transmission cable.
Accompanying drawing explanation
Fig. 1 is for improving front lightning protection overvoltage protector and cable connection diagram.
Fig. 2 is for improving rear lightning protection overvoltage protector and cable connection diagram.
Fig. 3 is the lightning protection overvoltage protector connector with cushion pad.
Fig. 4 is the connector along cable trend with one fixed width.
Fig. 5 is the connector with active joint.
In figure: 1-cable; 2-top board; 3-lower platen; 4-bolt; Depressor main body is crossed in 5-lightning protection; 6-arc lower groove; The upper deep-slotted chip breaker of 7-; Cushion pad under 8-; The upper cushion pad of 9-; 10-hinge.
Embodiment
Embodiment: a kind of connector for electric power lightning protection overvoltage protector; comprise top board 2 and lower platen 3; top board 2 stage casing has deep-slotted chip breaker 7; lower platen 3 stage casing has arc lower groove 6; described upper deep-slotted chip breaker 7 is oppositely arranged formation one cavity with arc lower groove 6; described top board 2 is connected respectively with lower platen about 3 two ends, and connected mode can be all connect with bolt 4.When cable 1 is installed lightning protection overvoltage protector, bolt 4 is unscrewed, then cable 1 is placed in the cavity that upper deep-slotted chip breaker 7 and arc lower groove 6 formed, tighting a bolt 4.Owing to there being the existence of cavity, avoiding the extruding to cable 1 when lower platen directly connects, thus cable 1 can be protected.
In order to have further protection to cable 1, be also provided with cushion pad 9 and lower cushion pad 8, described upper cushion pad 9 is placed in deep-slotted chip breaker 7, and described lower cushion pad 8 is placed in arc lower groove 6.The existence of cushion pad, makes the protected effect of cable 1 better.
In addition; while protection cable 1; in order to make the fixed effect of lightning protection overvoltage protector on cable 1 better; the width that described top board 2 and lower platen 3 move towards along upper deep-slotted chip breaker 7 or arc lower groove 6 is arranged between 10cm to 20cm; so-called width is exactly this connector when being arranged on cable, along the width that cable 1 moves towards.
In the utility model, it is that bolt 4 connects that the connector for electric power lightning protection overvoltage protector also can be set to upper lower platen one end, and the other end is that hinge 10 connects.Adopting this connected mode to be conveniently install, when installing lightning protection overvoltage protector, only bolt 4 need be backed out, cable 1, owing to being that the hinge 10 adopted connects, being placed in cavity, closing up lower platen, then tight a bolt 4 by the other end.
