Preferably, the telescopic link adopts insulating material, and the quantity of telescopic link has two, two the one end of telescopic link all with the side fixed connection of striking the arc stick.
Preferably, the spring is made of insulating and magnetism-insulating materials, one end of the spring is fixedly connected with the arc striking rod, and the other end of the spring is fixedly connected with one side of the section with the larger diameter value of the telescopic rod.
Compared with the prior art, the utility model discloses possess following beneficial effect:
1. this lightning protection pillar porcelain insulator, through the striking stick that cup joints with the fixed axle activity on the dead lever, when taking place the thunderbolt, the current that the striking stick produced the thunderbolt guides to discharge with the arc extinction cap and consume, the electro-magnet produced through the thunderbolt and the circular telegram produces magnetism this moment, and repel with magnet magnetism, thereby drive the striking stick and keep away from the certain distance of arc extinction cap, thereby improve the effect of lightning protection, and be favorable to cuting the power frequency afterflow.
2. This lightning protection pillar porcelain insulator, after the electric current elimination that produces the thunderbolt through the cooperation of arc extinction cap and striking stick, the magnetism of electro-magnet disappears, and telescopic link and spring reset to drive the striking stick and reset, ensure the effect of next time lightning protection, and the flexible length of accessible control telescopic link, be convenient for adjust the distance between striking stick and the arc extinction cap, thereby be convenient for adjust according to the difference of environment and use occasion.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a base; 2. an insulator body; 3. a magnet; 4. an arc extinction cap; 5. a mounting seat; 6. fixing the rod; 7. a fixed shaft; 8. an arc striking rod; 9. an electromagnet; 10. a telescopic rod; 11. a spring.
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, a lightning protection post porcelain insulator comprises a base 1, an insulator body 2 is fixedly connected to the top of the base 1, a magnet 3 is fixedly installed on one side of the top of the base 1, an arc extinguishing cap 4 is arranged in the middle of the side of the base 1, an installation base 5 is arranged on the top of the insulator body 2, a fixed rod 6 is fixedly connected to the side of the installation base 5, a fixed shaft 7 is fixedly sleeved at one end of the fixed rod 6, an arc striking rod 8 is movably sleeved on the fixed shaft 7, the arc striking rod 8 and the fixed shaft 7 can be connected in a hinged manner, an electromagnet 9 is fixedly sleeved at the bottom of the arc striking rod 8, telescopic rods 10 are fixedly installed on the side of the insulator body 2, the telescopic rods 10 are made of insulating materials, the number of the telescopic rods 10 is two, one end of each telescopic rod 10 is fixedly connected to the side of the arc striking rod 8, and the two telescopic rods 10 are used for ensuring, and utilize telescopic link 10 can improve the stability when striking stick 8 removes, the one end movable sleeve of telescopic link 10 is equipped with spring 11, spring 11 adopts insulating and magnetic insulating material, spring 11's one end and striking stick 8 fixed connection, and spring 11's the other end and one side fixed connection of the great section of telescopic link 10 diameter value, utilize the insulating and magnetic insulating material of spring 11, ensure that magnetism and electric current can not influence the normal work of spring 11, and utilize spring 11 on the one hand can ensure that striking stick 8 keeps corresponding distance with arc extinction cap 4 under normal conditions, on the other hand is convenient for striking stick 8's restoration.
The working principle is as follows: firstly, when a lightning strike occurs, the arc striking rod 8 can guide the current generated by the lightning strike and the current is discharged and consumed between the arc striking rod 8 and the arc extinguishing cap 4, then, when the current generated by the lightning strike is guided by the arc striking rod 8, the electromagnet 9 generates magnetism by electrifying the current generated by the lightning strike and repels the magnetism of the magnet 3, so that the arc striking rod 8 movably sleeved with the fixed shaft 7 on the fixed rod 6 is driven to move, the distance between the arc striking rod 8 and the arc extinguishing cap 4 is increased, the telescopic limit of the telescopic rod 10 is passed, the distance between the arc striking rod 8 and the arc extinguishing cap 4 is ensured not to be overlarge, and finally, when the lightning strike current is completely consumed, the magnetism on the electromagnet 9 disappears, the telescopic rod 10 drives the spring 11 to reset, and the arc striking rod 8 is driven to.
