Description

Discharge gap type lightning conductor connecting structure capable of ensuring distance

Technical Field

The utility model relates to the field of communications, especially, relate to the clearance formula of discharging lightning conductor connection structure of assurance distance.

Background

In the thunderstorm season, a plurality of accidents that communication equipment is damaged by thunder and lightning occur, and overhead communication lines are direct victims. In some places, even serious accidents such as fire disasters and casualties caused by lightning strike, so that lightning strike prevention becomes a key for keeping smooth communication in thunderstorm seasons.

The communication line acceptance specification GB 51171-20168.8.8 specifies: and crossing with a power line of more than 10KV, installing discharge gap type lightning protection wires on electric poles at two sides, and disconnecting the lightning protection wires by 5 cm. (2 m from the ground)

The communication line acceptance specification GB 51171-2016: 8.4.2 specifies: the overhead suspension wire crosses the power transmission line outside the subscriber lead-in wire covered wire, the suspension wire on the overhead optical (electrical) cable rods at two sides of the crossing barrier is grounded, the ground wire on the rods is disconnected with a discharge gap of 50mm at the position 2.0m higher than the ground, and the stay wires on the electric poles at two sides are additionally provided with insulators at the position 2.0m higher than the ground to be electrically disconnected.

However, in the actual construction process, the discharge gap cannot meet the specification requirement due to various reasons, and a serious result is caused.

In the prior art, the following are exemplified:

1) when the reserved lightning conductor nail penetrating hole is formed in the cement rod, a steel wire with the diameter of 4.0mm is led out upwards from the nail penetrating nut on the rod, and the steel wire is 10cm higher than the top of the rod to serve as a lightning conductor; a steel wire with the diameter of 4.0mm is connected to the ground through a grounding penetrating nail nut at the lower part of the electric pole and enters the ground, and the steel wire is bent to below 70cm underground and horizontally extends to serve as a ground wire.

2) When no reserved lightning conductor through hole is formed in the cement pole, a steel wire with the diameter of 3.0mm is used for bundling four rings of lightning conductors (steel wires with the diameter of 4.0 mm) at a position 10cm below the pole top and fixing the lightning conductors, the lightning conductors are bent upwards and penetrate into the pole body from the pole top and penetrate downwards until the pole follows the ground, the lightning conductors are bent from the pole bottom and horizontally extend, the lightning conductors are tightly attached to the pole body and exceed the pole top by 10cm, and the middle of the pole body is downwards fixed by winding four rings of steel wires with the diameter of 3.0mm every 50 cm.

3) When the electric pole guy wire is used as a lightning conductor, a steel wire with the diameter of 4.0mm is respectively tied up for four circles at the positions which are 10cm and 60cm away from the top of the pole, and then the steel wire is pressed into a guy wire hoop of the cement pole; when the lightning conductor is installed on the wood pole, a steel wire with the diameter of 4.0mm is nailed by a staple bolt and then pressed into the pull wire upper handle. The lightning conductor is 10cm beyond the top of the pole. The cement pole and the wood pole are installed by using the pull wire as the lightning conductor.

4) When the urban pole line crosses a high-voltage (10kv) power line, the wood poles at two sides can be provided with discharge gap type lightning conductors, and the installation method and the specification are the same as those described above. If cement poles are arranged on two sides of the crossing part, the installation method and the specification are the same as those of the cement poles, and only the lightning conductor is fixed by winding four circles of 3.0mm steel wires on each 50cm of the cement poles.

The existing technology can not stipulate the distance of the discharge gap, and the lightning protection effect is influenced.
