The utility model discloses a following technical scheme realizes above-mentioned purpose, a many parallelly connected arrester of resistance post, by the parallelly connected constitution of a plurality of resistance posts, this arrester bottom installation mount, the mount passes through fixing bolt and installs at high-voltage line tower top, the resistance post comprises the resistance card of range upon range of setting, and is adjacent on the resistance post the crisscross alignment of resistance card, the resistance post is four, relative two the resistance post height is unanimous, connects through first connecting plate, two in addition the resistance post height is uniform and is connected through the second connecting plate.
Preferably, the distance between the resistor discs on the resistor columns is larger than the thickness of the resistor discs.
Preferably, the intersection of the first connecting plate and the second connecting plate is fixed by a connecting bolt.
Preferably, the resistance post both ends all set up the electrode post, and first connecting plate and second connecting plate both ends all set up the waist hole, pass the waist hole through fastening bolt and make first connecting plate and second connecting plate fixed with the electrode post respectively.
Preferably, an electric heating tube is installed between the resistance columns, a power-on seat is arranged at the bottom end of the electric heating tube, and the power-on seat is installed on the fixing frame.
Compared with the prior art, the beneficial effects of the utility model are that:
1. through the resistance post of crisscross alignment, make the resistance card on the resistance post stretch into between two resistance cards on the adjacent resistance post, make many resistance post type's arrester wholeness become strong through this kind of mode of putting, the volume reduces, is favorable to installation, dismantlement and transportation, and the interval between the adjacent resistance post is little moreover, has also improved stability.
2. Through set up waist hole on two connecting plates, make the interval between the resistance post adjust along with the demand, it is more convenient to use.
3. The electric heating tube is arranged in the middle area surrounded by the resistance column, so that the resistance column can be heated by the electric heating tube in rainy and snowy weather, the icing of the lightning arrester is reduced, and the use effect of the lightning arrester is prevented from being influenced by the icing.
