Abstract
The utility model discloses an adjustable negative angle protecting pin, which comprises an adjusting sleeve and a protecting pin. An adjusting nut is arranged on the adjusting sleeve, and the pin-shaped adjusting pin is movably connected with the adjusting sleeve. When the adjustable negative angle protecting pin is adopted, the adjusting sleeve is firstly mounted on a chipboard outside a head of a cross arm of a transmission line tower, an included angle between the adjusting sleeve and the ground is adjusted to be 90 degrees to the greatest extent, then the protecting pin penetrates through the adjusting sleeve from inside to outside, and the adjustable negative angle protecting pin can be used just by means of screwing the adjusting nut. The adjusting nut on the adjusting sleeve can be loosened so as to move the protecting pin to realize the optimal lightning protecting angle according to needs. The adjustable negative angle protecting pin can effectively reduce hazards of lightning damage to transmission line equipment, further enhances safety of transmission lines, is simple in structure and convenient in operation, and can effectively improve lightning resistance level of the transmission line.
Description
Technical field
The utility model belongs to the anti-damage to crops caused by thunder technical field of electric power line pole tower, particularly a kind of adjustable negative angle protection pin.
Background technology
In the electric power line pole tower running, to charging equipment, promptly the protection of the exterior overvoltage of lead is mainly finished by overhead ground wire.Because of the geographical position and the surrounding enviroment at transmission line place are not quite similar, weather conditions also are fast changing, and formed thunder and lightning kind also is diversified under the different condition.Especially in the statistics of transmission line tripping operation,, damage to crops caused by thunder still accounts for the larger specific gravity of sum because of causing the number of times of tripping operation.So, only rely on overhead ground wire to carry out lightning protection, can not satisfy the lightning protection needs of transmission line, and have many hidden danger.If not relevant protection, in a single day transmission line is struck by lightning, and probably meets accident, and causes power failure etc., and normal economy, life are caused certain influence.
The utility model content
The utility model provide a kind of can effectively improve the anti-thunder lightning withstand level of transmission line, simple in structure, flexible operation, highly versatile, easy to assembly, can effectively reduce the adjustable negative angle protection pin of damage to crops caused by thunder to transmission line equipment harm.
A kind of adjustable negative angle is protected pin, comprises regulating sleeve pipe and protection pin, on the described adjusting sleeve pipe adjusting nut is set, and described protection pin is a needle-like, and described protection pin and adjusting sleeve pipe flexibly connect.
Utilize the utility model; to regulate earlier on the card that sleeve pipe is installed in the electric power line pole tower cross-arm head outside; about all can install; note regulating the horizontal level of sleeve pipe; make the adjusting sleeve pipe become 90 ° with ground as far as possible, unscrew the adjusting nut of regulating on the sleeve pipe then, will protect pin to penetrate the adjusting sleeve pipe from inside to outside; screw adjusting nut, can use.Owing to regulate on the sleeve pipe adjusting nut be set, can become flexible adjusting nut according to actual needs, move the position of protection pin, to reach best anti-thunder, lightning-arrest angle.
Utilize the utility model, can effectively reduce the harm of damage to crops caused by thunder to transmission line equipment, the fail safe of transmission line further strengthens, and the utility model is simple in structure, easy to operate, highly versatile can not impact the normal circuit maintenance yet, is a kind of device that can effectively improve the anti-thunder of transmission line, lightning withstand level.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1: a kind of adjustable negative angle is protected pin, comprises regulating sleeve pipe 1 and protection pin 2, on the described adjusting sleeve pipe 1 adjusting nut 3 is set, and described protection pin 2 is a needle-like, and described protection pin 2 and adjusting sleeve pipe 1 flexibly connect.
Utilize the utility model; to regulate earlier on the card that sleeve pipe 1 is installed in the electric power line pole tower cross-arm head outside; about all can install; note regulating the horizontal level of sleeve pipe 1; make adjusting sleeve pipe 1 become 90 ° with ground as far as possible, unscrew the adjusting nut of regulating on the sleeve pipe 13 then, will protect pin to penetrate from inside to outside and regulate sleeve pipe 1; screw adjusting nut 3, can use.Owing to regulate on the sleeve pipe 1 adjusting nut 3 be set, can become flexible adjusting nut 3 according to actual needs, move the position of protection pin 2, to reach best anti-thunder, lightning-arrest angle.
Utilize the utility model, can effectively reduce the harm of damage to crops caused by thunder to transmission line equipment, the fail safe of transmission line further strengthens, and the utility model is simple in structure, easy to operate, highly versatile can not impact the normal circuit maintenance yet, is a kind of device that can effectively improve the anti-thunder of transmission line, lightning withstand level.
