Technical Field

The utility model belongs to the technical field of the pole is drawn down to the cable, concretely relates to pole is drawn down to single cable that returns.

Background

The arrester connecting wire on the pole is drawn down to traditional cable all is direct fixed connection together with the cable, no matter be installation and dismantlement all very wasted time, and traditional when overhauing the arrester, all need cut off whole circular telegram equipment on this cable draw down the pole, make this cable draw down the pole and be in the state of outage, the staff just can overhaul the arrester, nevertheless, through cutting off the power supply, can cause the trouble of having a power failure to peripheral resident, the influence is to resident's normal power consumption, therefore, we provide a single-circuit cable and draw down the pole, in order to solve above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a pole is drawn down to single cable return to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a single-circuit cable downlead, includes the stand, the upper end of stand sets up drop out fuse holder, drop out fuse holder's the even drop out fuse that sets up on the surface, set up the stay wire on the drop out fuse, drop out fuse electric connection wire, the wire is connected the arrester lead wire through the removable fastener, the synthetic zinc oxide arrester of other end fixed connection of arrester lead wire, synthetic zinc oxide arrester passes through bolt fixed connection arrester holder, the bottom of stand sets up earthing device.

Preferably, the grounding device comprises a ground wire and a metal grounding body.

Preferably, the number of the drop-out fuse supports is two, the two drop-out fuse supports are arranged at the upper end of the stand column, and the two drop-out fuse supports are connected through a lead.

Preferably, each wire is connected with a lightning arrester lead through a removable wire clamp, and each lightning arrester lead is correspondingly connected with each synthetic zinc oxide lightning arrester.

Preferably, the synthetic zinc oxide arrester is electrically connected with a grounding lead, and the grounding lead is electrically connected with a grounding device.

The utility model discloses a technological effect and advantage: this single-circuit cable downlead pole through set up removable fastener on the wire, can conveniently be to arrester live working, through set up anticorrosive in earthing device, can prevent to the corruption of ground lead wire, avoids influencing the effect of taking shelter from thunder, and the device can be convenient for the live working of arrester, avoids causing danger to the staff, conveniently dismantles and installs the arrester lead wire moreover, and the operation of being convenient for is simple.
