[ field of technology ]
The invention belongs to the field of lightning rod design, and particularly relates to a clamp for preventing a lightning rod from falling down and a lightning arrester.
[ background Art ]
Lightning rod, also known as lightning rod, is widely used in power plant, transformer station, etc. as a device for protecting building or electric equipment from lightning. The principle of the lightning rod is that a metal rod is arranged at the top end of a tall building (or a pole tower), a metal wire is connected with a piece of metal buried underground, and the point discharge of the metal rod is utilized to gradually neutralize electricity carried by cloud layers and electricity on the ground, so that accidents cannot be caused.
The lightning rod of the transformer substation in regions with high strong wind frequency such as northwest, north China, northeast China and the like comprehensively considers the strong wind intensity and frequency, and the lightning rod is in a swinging state for a long time. The high-frequency reciprocating stress easily causes fatigue damage of bolts at the flange of the lightning rod, and then the lightning rod falls down. However, other equipment is easy to damage due to the fact that a lightning rod of the transformer substation is broken and falls, and normal operation of the transformer substation is affected.
[ invention ]
The invention aims to overcome the defects of the prior art, and provides a transformer substation lightning rod capable of preventing falling down, so that secondary loss caused by the fact that the lightning rod falls down to smash adjacent equipment after a flange plate bolt fails is avoided.
In order to achieve the above purpose, the invention adopts the following technical scheme:

wherein, the lower extreme and the building of ground wire post are connected, and the lightning rod body passes through the ring flange and installs perpendicularly at the top of ground wire post, and the upside and downside symmetry of ring flange is provided with a plurality of stiffening plates, sets up a clamp between two adjacent stiffening plates, and the clamp joint is on the ring flange, and the bottom plate of its draw-in groove links firmly with the lateral wall of ground wire post.
Preferably, the plurality of hoops are circumferentially and uniformly distributed on the flange plate.
Preferably, the number of the plurality of clips is 8 to 16.
Compared with the prior art, the invention has the following beneficial technical effects:
the clamp comprises the clamping plate and the supporting plate, when the lightning rod body swings under the action of external force, the supporting plate can play a supporting role on the lightning rod body, so that the stress of the bolt is reduced, and the service life of the bolt is prolonged. Cardboard joint is on the ring flange and links firmly with the ground terminal, the bolt failure when the ring flange leads to the ring flange separation, because the draw-in groove card can be spacing on the ring flange, the inclination of limiting the upper portion lightning rod body effectively, can effectively reduce the overturning moment that the lightning rod body produced, prevent that the ring flange separation distance from continuing to grow and leading to dropping, simultaneously when the ring flange appears inclining, the backup pad can play the effect of support to the lightning rod body, therefore this clamp simple structure, convenient to use can effectively prevent the lightning rod body from dropping the secondary loss that causes from the high altitude.
The vertical connecting plate of the supporting plate adopts an arc-shaped structure, so that the deformation resistance of the vertical connecting plate is enhanced, and the compressive resistance of the vertical connecting plate is improved.
