Technical Field

The invention relates to a lightning arrester base, in particular to an anti-dredging integrated lightning arrester base.

Background

Because the rainwater is in more areas at the ultrahigh-voltage direct-current station, and the lightning-protection base explosion-proof nozzle is arranged, rainwater flows into the lightning arrester base through the explosion-protection nozzle during raining, if the lightning arrester is installed to be slightly inclined, water flow cannot completely flow out from a channel in the middle of the base, and rainwater can be accumulated at one corner with a relatively low horizontal position of the lightning arrester.

Because the bolt groove bottom in arrester base four corners is totally sealed by bolt and gasket, leads to the rainwater to gather and can't get rid of in the bolt groove, if handle untimely can cause following several problems:

1. leakage current of the lightning arrester can flow into the ground through the base with low insulation, so that the leakage current monitoring of the lightning arrester is influenced;

2. the leakage current value detected by an online monitor of the lightning arrester is inaccurate;

3. if lightning stroke or overvoltage directly discharges to the ground, the filter field equipment is arranged more closely, and the electric discharge can cause the damage of an adjacent equipment bracket and even an equipment body; when in lightning stroke, lightning current is led into the ground screen from the lightning arrester through the ground wire and is discharged quickly; if the base is low in insulation, lightning current passes through the base, and personal and property safety can be endangered.

Disclosure of Invention

The invention mainly solves the problems in the prior art and provides a lightning arrester base capable of effectively preventing water and dredging water flow.

The invention is realized by the following technologies:

an anti-dredging integrated lightning arrester base, comprising: the base and the fixing mechanism are made of insulating materials, mounting holes are formed in four corners of the base, bosses surrounding the mounting holes are arranged on the outer sides of the mounting holes, and water can be prevented from flowing into the mounting holes; the fixing mechanism is arranged on the mounting hole; the fixing mechanism includes: the water-proof cover, the insulating block, the water guide gasket, the fixing bolt and the fixing nut; the insulating block is arranged above the mounting hole and positioned on the inner side of the boss, the water guide gasket is arranged below the mounting hole, and the fixing bolt penetrates through the insulating block, the mounting hole and the water guide gasket and is fixed by the fixing nut; the waterproof cover covers on boss, insulating block and fixing bolt, can completely cut off the rainwater effectively.

The water guide gaskets comprise gaskets and C-shaped gaskets arranged on two end faces of the gaskets, and openings of the two C-shaped gaskets can be arranged in the same direction, the opposite direction and any angle direction; rainwater can flow in from the opening of one C-shaped gasket and then flow out from the opening of the other C-shaped gasket.

The invention has the beneficial effects that:

1. the protective cover effectively prevents rainwater from entering;

2. the outer side of the mounting hole is provided with a boss surrounding the mounting hole, so that the waterproof effect is further enhanced;

3. the openings of the two C-shaped gaskets on the water guide gasket can dredge water guide in time.
