The invention relates to a pressing plate and insulator adaptive anti-thunder device. The pressing plate and insulator adaptive anti-thunder device comprises an insulator. The top end of the insulator is provided with a puncturing pressing plate, and one side of the puncturing pressing plate is provided with a metal connecting plate. The two ends of the metal connecting plate are provided with holes. One side of the metal connecting plate presses the puncturing pressing plate through a hole, and the other side of the metal connecting plate is provided with a conductive bolt. The lower end of the insulator is fixedly provided with a three-hole metal connecting plate. The far end of the three-hole metal connecting plate is provided with an insulation connecting plate, and the metal part in the middle of the insulation connecting plate is pressed by a fuse wire. The other end of the fuse wire presses the metal part in the middle of the three-hole metal connecting plate. The puncturing pressing plate is internally provided with a puncturing part, the angle between the three-hole metal connecting plate and the insulation connecting plate is 60 degrees, and the angle between the conductive bolt and the insulation connecting plate ranges from 15 degrees to 30 degrees. According to the pressing plate insulator adaptive anti-thunder device, the anti-thunder capability of an insulation wire is improved, the number of exposed points on a circuit is reduced, the stability of power grid operation is improved, and a new insulation anti-thunder element is achieved through the design improvement.
Description
technical field [0001] The invention relates to a pressure plate insulator adapted lightning protection device. Background technique [0002] The existing lightning protection method for insulated wires is to peel off a part of the insulation skin on the insulated wires near the insulator, and install a lightning protection device to generate a discharge gap to lead lightning into the ground. [0003] The discharge gap of the existing lightning protection method cannot be reliably fixed with the swing of the wire, and there is a possibility of misoperation due to the small safety distance when the wire swings relatively large; when the lightning protection device is installed, its effect is largely determined by the construction personnel. At the technical level, it is impossible to be accurate to a unified standard; a large number of exposed points on the insulated circuit increases the possibility of a short circuit to the ground when foreign objects fall. The existing li...
