Abstract
The utility model discloses a lightning protection strut composite insulator, comprising an insulator body, a wire clamping piece on the top end of the insulator body and a cross arm below the insulator body, wherein the wire clamping piece comprises a press block seat and a mobile press block above the press block seat, the middle part on the lower surface of the mobile press block is provided with a ratchet penetrating an insulation layer of an insulated wire, and the press block seat of the wire clamping piece is connected with an extending starting rod. In the utility model, by adopting the structure in the lightning protection strut composite insulator, the safety coefficient is increased, the installation is convenient and the maintenance cost is reduced.
Description
Technical field
The utility model relates to high voltage protective electrical equipment, relates in particular to the lightning protection pillar composite insulator.
Background technology
Electric power system extensive use aerial insulated wire, the lightning-caused breaking problem of aerial insulated wire is in rising trend year by year, is perplexing the safe operation of electric power network, so must adopt anti-thunder insulator in the overhead power line, existing anti-thunder insulator exists installs inconvenience, the deficiency that maintenance cost is higher.
The utility model content
Technical problem to be solved in the utility model is: a kind of lightning protection pillar composite insulator is provided, and this kind lightning protection pillar composite insulator is easy for installation, can reduce maintenance cost.
Solve this technical problem, the technical solution of the utility model is: a kind of lightning protection pillar composite insulator, comprise the clamp piece on insulator body, insulator body top and the cross-arm of insulator body below, described clamp piece comprises the mobile briquetting of briquetting seat and briquetting seat top, the lower surface middle part of described mobile briquetting has the ratchet that penetrates the insulated conductor insulating barrier, is connected with the starting rod that stretches out on the briquetting seat of described clamp piece.
Described clamp piece is covered with insulating shield.
Be with insulating sleeve on the described starting rod.
The utility model lightning protection pillar composite insulator adopts such structure, has increased coefficient of safety, and is easy for installation, can reduce maintenance cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model lightning protection pillar composite insulator is done explanation in further detail;
Fig. 1 is the structural representation of the utility model lightning protection pillar composite insulator;
In Fig. 1,1, insulating shield; 2, insulated conductor; 3, mobile briquetting; 4, starting rod; 5, cross-arm; 6, insulator body; 7, briquetting seat.
Embodiment
As shown in Figure 1, the lightning protection pillar composite insulator comprises the clamp piece on insulator body 6, insulator body 6 tops, cross-arm 5, insulating shield 1 and the starting rod 4 of insulator body 6 belows, clamp piece comprises the mobile briquetting 3 of briquetting seat 7 and briquetting seat 7 tops, insulated conductor 2 is clamped between mobile briquetting 3 and the briquetting seat 7 when installing, the lower surface middle part of mobile briquetting 3 has the ratchet that penetrates insulated conductor 2 insulating barriers, be connected with the starting rod 4 that stretches out on the briquetting seat 7 of clamp piece, insulating shield 1 covers clamp piece, is with insulating sleeve on the starting rod 4.Such structure, starting rod is connected with the clamp piece assembling, and when thunderbolt took place, thunder and lightning discharged by starting rod and burns, and effectively prevents lightning-caused breaking.The mobile briquetting of clamp piece has ratchet, need not the insulated conductor insulating barrier during installation, avoid core water inlet and corrosion, and easy for installation, reduce maintenance cost.
