Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and embodiments.
A grounding lead connecting structure comprises a grounding lead 1, a guardrail 2, a guardrail bottom plate 3 and an oil tank bottom plate 4, wherein the guardrail 2 is arranged outside the grounding lead 1 and is fixedly connected with a transformer oil tank through the guardrail bottom plate 3 and the oil tank bottom plate 4; the guardrail 2 is formed by bending an aluminum alloy plate, and round holes are uniformly distributed on the aluminum alloy plate; guardrail bottom plate 3 welding is in guardrail 2's inboard, and oil tank bottom plate 4 is fixed to be set up on transformer tank, guardrail bottom plate 3 and oil tank bottom plate 4's shape and quantity phase-match, and the two hook is connected.
The diameter of a round hole in the aluminum alloy plate of the guardrail 2 is 40mm, and the hole pitch is 100 mm.
The guardrail bottom plate 3 is provided with a hole, the hole comprises a hole 10 and a groove 11, and the hole 10 is communicated with the groove 11; the oil tank soleplate 4 comprises a soleplate 7, a hanging shaft 8 and a hanging plate 9, wherein both the soleplate 7 and the hanging plate 9 are circular plates; the rear end face of a bottom plate 7 of the oil tank bottom plate 4 is fixed on a transformer oil tank, the front end face of the bottom plate 7 is connected with one end of a hanging shaft, the other end of the hanging shaft is connected with the rear end face of a hanging plate, and the front end face of the hanging plate is matched with a hole in the guardrail bottom plate 3; the aperture of the hole is larger than the diameter of the hanging plate and smaller than the diameter of the bottom plate; the diameter of link plate is greater than the width in groove, and peg 8 and groove 11 phase-match.
Guardrail 2 is buckled the combination mutually by two aluminium alloy plates and is formed, and two aluminium alloy plates are fixed through supporting 5 and the 6 concatenation of bolt of aluminium strip.
In practical application, a guardrail is added outside the grounding lead. The aluminum alloy plate is provided with round holes with the diameter of 40 which are uniformly distributed, and the hole pitch is about 100 mm. To prevent small animals or other objects from approaching the grounding point in case of a malfunction of the transformer.
