Abstract
The utility model discloses a lightning insulator which can support the function of conductor wire, and can release induced voltage generated by lightning impulse to the earth ground; an upper fitting (7) is connected with a screw bolt (6), an electrode (4), and a valve block (2); the electrode is serially and electrically connected with the screw bolt and a lower fitting (1); one end of the earthing wire is connected with one end of the lower fitting (1) to earth. When the induced voltage generated by lightning impulse is bigger than the conducting values of the valve block (2), the induced voltage generated by lightning impulse is released to the earth ground through the upper fitting (7) connected with the snail electric pole(4), the valve block (2), the electric pole, the connecting bolt, the lower fitting (1) and the earthing wire, and the insulator is not punctured; inversely, the valve block is in resistor state, and the insulator supports the function of conducting wire.
Description
Affiliated technical field:
The utility model is that a kind of transmission line is supported the insulator that lead is used, and impacted by thunder and produce the lightning protection insulator that the support lead is used in the induced voltage release the earth.
Background technology:
At present, the insulator that known support lead is used is porcelain and synthesizes two types, produces the breakdown power outage that causes of induced voltage insulator when transmission line is subjected to lightning impulse.
Summary of the invention:
For being impacted by thunder, the insulator that overcomes present support lead application produces induced voltage puncture causing power outage; the utility model provides that insulator not only can be supported lead but also can be discharged into the earth with suffering to produce induced voltage behind the lightning impulse, and the protection insulator is not damaged.The utility model solves technical scheme that its technical problem adopts, be to make the plug (5) that metal oxide valve block (2) are housed between the gold utensil (1) down at gold utensil on the insulator (7), appearance is adorned the synthetic overcoat (3) of insulation again, the electrode (4) of band connecting bolt (6) is equipped with in valve block (2) both sides, bolt (6) other end connects gold utensil (7) respectively, following gold utensil (1) gold utensil (1) down is connected with ground wire, behind lightning impulse, produce induced voltage greater than valve block (2) conduction value, voltage is by last gold utensil (7) connecting bolt (6), electrode (4), valve block (2), gold utensil under the electrode connecting bolt (1), earth connection is discharged in the earth and goes, and reaches the not breakdown purpose of insulator.Seal cover (8) is housed, the following drain pan (9) that is equipped with above the gold utensil below the last gold utensil.
The beneficial effects of the utility model are can play to support in the lead effect on transmission line, also the induced voltage that produced by lightning impulse can be discharged in the earth and go, and play the not breakdown effect of insulator.It is simple that metal oxide valve block and electrode structure are housed in the lightning protection insulator plug.
Description of drawings
Accompanying drawing is the longitudinal sectional view of the utility model embodiment.
Among the figure: 1, following gold utensil, 2, valve block, 3, the synthetic overcoat of insulation, 4, electrode, 5, interior cover, 6, connecting bolt, 7, go up gold utensil, 8, seal cover, 9, drain pan.
Embodiment
As shown in drawings, overall structure of the present utility model comprises: following gold utensil (1), metal oxide valve block (2), insulation are synthesized overcoat (3), electrode (4), interior cover (5), connecting bolt (6), are gone up gold utensil (7), seal cover (8), drain pan (9).The performance of the material that interior cover (5) is selected for use should satisfy lightning protection insulator tension, bending resistance, antitorque mechanical electric performance demands.The peak on voltage value of metal oxide valve block (2) should be less than the maximum wet withstand voltage of insulator.
Claims (1)
1, a kind of lightning protection insulator, system is linked in sequence by last gold utensil, connecting bolt, electrode, valve block, electrode, following gold utensil, earth connection etc., make plug by interior cover parcel then, the synthetic overcoat of insulation is equipped with in the outside, it is characterized in that: valve block one side is connected with last gold utensil by the electrode connecting bolt, opposite side is connected with following gold utensil by the electrode connecting bolt, and earth connection one end connects an end ground connection of gold utensil down; Seal cover is housed below the last gold utensil, above the following gold utensil drain pan is housed.
