Description
Technical field
The utility model relates to the electric power system overhead distribution, particularly a kind of lightning protection pillar insulator that prevents electric power overhead insulated conductor lightning-caused breaking.
Background technology
The common pedestal post insulator of general use is as the supporting role device of lead in the existing overhead power line, but common pedestal post insulator is because there is following shortcoming in its structural limitations: 1, only play the support wire effect, there is no lightning protection function, must install the supporting use of zinc oxide arrester additional; Also need divest the insulating barrier of insulated cable when 2, installing lightning arrester additional, cause rainwater to divest an infiltration along insulating barrier, the plain conductor of corrosion insulated cable; 3, if big lightning current by lightning arrester, can cause lightning arrester to hold be can't stand and damage, cause short circuit ground connection, cause the insulated cable broken string, increased the failure rate of system; 4, lightning arrester not only bears the power-frequency voltage effect for a long time, also will bear the effect of lightning overvoltage and power frequency continued flow simultaneously off and on, and aging easily, its fault is a lot, and cost is very high; 5, construction and installation complexity needs the stripping of insulatin layer, causes core water inlet and corrosion etc.
Summary of the invention
The purpose of this utility model is to provide a kind of and had not only played insulation and support the lead effect, but also have the circuit of preventing thunderbolt effect and can reusable lightning protection pillar insulator in power circuit.
For achieving the above object, a kind of lightning protection pillar insulator of the utility model, comprise tension seat and be installed in composite insulator below the tension seat, the steel pin is installed below the described composite insulator, steel underfooting face is provided with the installation nut, and described tension seat vertical direction is provided with the line ball piece, and vertical lower is provided with the insulation starting rod, tension seat is fixedlyed connected with line ball piece, insulation starting rod respectively by clamping screw, and insulating sleeve is arranged on the outside of tension seat and line ball piece; Described steel pin one side is set with the extinguishing arc head by active connection.
The middle part of described tension seat, line ball piece is provided with first groove and second groove.
Described extinguishing arc head end is provided with the thunderbolt indicator board.
After adopting technique scheme, by composite insulator and insulation starting rod are set at tension seat, realize that post insulator and preventing arc wire clamp unite two into one, have insulation and support lead, anti-lightning strike, simplify circuit, reduce cost and can reusable characteristics; And composite insulator employing composite material, good insulation preformance, creepage distance is big, has improved anti-filthy level; Insulating shield adopts silastic material simultaneously, good insulation preformance, and anti-aging, fire resistance is good, can effectively improve the useful life of tension seat and line ball piece.
Description of drawings
Fig. 1 is a kind of lightning protection pillar insulator structural representation of the utility model;
Fig. 2 is the right view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing a kind of lightning protection pillar insulator of the utility model is described further;
By Fig. 1, Fig. 2 as seen, a kind of lightning protection pillar insulator of the utility model, comprise tension seat 1 and be installed in composite insulator 2 below the tension seat 1, below the described composite insulator 2 steel pin 3 is installed, be provided with below the steel pin 3 nut 4 is installed, described tension seat 1 vertical direction is provided with line ball piece 5, and vertical lower is provided with insulation starting rod 6, tension seat 1 is fixedlyed connected with line ball piece 5, insulation starting rod 6 respectively by clamping screw 7, and insulating sleeve 8 is arranged on the outside of tension seat 1 and line ball piece 5; Described steel pin 3 one sides are set with extinguishing arc 9 by active connection.When thunderbolt takes place, cause the flashover discharge between insulation starting rod 6 and the steel pin 3, form short-channel, lasting power frequency arc moves to burning between insulation starting rod 6 and the steel pin 3, avoids burn with guardwire.Simultaneously, because insulation starting rod 6 gets around composite insulator 2 full skirts and transfers to the optimal discharge gap, discharge effect is better, effectively prevents from burning out the full skirt of composite insulator 2, and composite insulator 2 wherein plays pillar, insulation and the antifouling effect of supporting lead.
Wherein, described tension seat 1, line ball piece 5 middle parts are provided with first groove 11 and second groove 51, can be provided with puncture ratchet 10 on it as required; When being provided with puncture ratchet 10, the insulating barrier that need not divest lead can be realized the puncture energising, avoids core water inlet and corrosion, makes things convenient for installation, can greatly alleviate operator's labour intensity; When being provided with puncture ratchet 10, lead divests insulating barrier and can switch on.
In the present embodiment, described insulation starting rod 6 mounting parts are detachable, the installation position semicircular in shape, by clamping screw 7 be fixed on tension seat 1 below, like this not needing as removable laying down in the lightning protection insulation column, as common post insulator; Described extinguishing arc 9 mode that adopt the lower end screw to screw in are installed in the steel pin 3, and with extinguishing arc 9 prolongation, its length is greater than the length of full skirt on the composite insulator 2, in insulation starting rod 6 and extinguishing arc 9 discharge, increase the distance of electric arc and composite insulator 2 like this, when thunderbolt takes place, not only can protect electric wire, also can avoid burning out the full skirt on the composite insulator 2, make it reusable; Described extinguishing arc 9 upper end are provided with thunderbolt indicator board 91, thunderbolt indicator board 91 falls for the plastic cement thin plate, in the line thunderbolt time to extinguishing arc 9 discharge after, high arc temperature is with 91 fusings of thunderbolt indicator board, which insulation column the maintenance personal just can accurately judge according to thunderbolt indicator board 91 and suffer thunderbolt, realizes maintenance fast; Insulating sleeve 8 is arranged on the outside of tension seat 1 and line ball piece 5, and it adopts silastic material to make, and has good insulation performance performance, ageing resistace and fire resistance.
