Embodiment
Further illustrate below in conjunction with accompanying drawing:
As shown in accompanying drawing 1-5: the utility model comprises insulator, wherein: described insulator one end is fixed on wire, described conductive line surfaces is provided with preformed armor rods, the other end of described insulator is fixed on by nut on the connecting plate of energy height up and down, the connecting plate of energy height up and down is provided with lightning arrester, have spacing between described lightning arrester and described preformed armor rods, described gap length is 60mm to 100mm; As preferably, described wire is steel reinforced aluminium conductor, described preformed armor rods is wrapped on wire, described preformed armor rods is aluminium alloy preformed armor rods, the connecting plate of described energy height up and down comprises L-type brace, V-type brace, and be fixedly connected with by adjustable nut between described L-type brace and V-type brace, the other end of described insulator is fixed on L-type brace by nut, described lightning arrester is movable to be connected on V-type brace, is provided with cross-arm below described L-type brace.
The length of described spacing is 60mm or 100mm, and its lightning-arrest effect is best, has spacing between described lightning arrester and described preformed armor rods, and the length of described spacing is joined chummy by insulator lightning impulse breakdown voltage value calculating on electric pole.
Described lightning arrester adopts metal oxide arrester, it is not charged when metal oxide arrester body normally runs, when line lightning overvoltage, aluminium alloy preformed armor rods electrode and lightning arrester spacing are prior to insulator breakdown gap, utilize the nonlinear wind vibration that zinc oxide is good, receive superpotential energy of releasing, reach other electrical equipment protecting insulator and wire directly to connect not damaged; First by the minimum air void that this insulator lightning impulse withstand voltage calculates, then the length of spacing between the lightning arrester carried out on up-down adjustment connecting plate and aluminium alloy preformed armor rods.
The purpose of this utility model, feature and advantage will in conjunction with the embodiments, are further described with reference to accompanying drawing.To contribute to understanding the utility model by embodiment, but not limit content of the present utility model.All distortion that those of ordinary skill in the art can directly derive from content disclosed in the utility model or associate, all should think protection range of the present utility model.
