Embodiment 1

[0027] Such as figure 1 , figure 2 , image 3 and Figure 4As shown, according to a double-disk clockwork type arc extinguishing and lightning protection device of the present invention, the arc extinguishing and lightning protection device includes an arc extinguishing and lightning protection housing 1, an arc extinguishing cylinder 2, A rotary disc 3 and B rotary disc 4 and a drive The switching device 5 is horizontally provided with a rotatable central shaft 10 in the arc extinguishing and lightning protection housing 1, the A rotary table 3 and the B rotary table 4 are slidably arranged on the central shaft 10, and the A rotary table 3 and the B rotary table The circumferential side wall of 4 is uniformly provided with a plurality of placement grooves 30 for placing gas pills in the radial direction, and a gas pill trigger position is provided on the lower side wall of the arc extinguishing and lightning protection shell 1, and the arc extinguishing The cylinder 2 is ...

Embodiment 2

[0031] The difference between the second embodiment and the first embodiment is that only the B sleeve 400 is fixedly sleeved on the central axis 10, such as Figure 4 As shown, the A turntable 3 is directly slidably arranged on the central shaft 10, and the spiral slide rail 301 may or may not be provided directly on the central shaft 10, and the B turntable 4 is slidably arranged on the B sleeve 400, and the B turntable 4 Set the central shaft 10 through the B sleeve 400, and set a spiral slide rail 401 on the outer wall of the B sleeve 400, and the B turntable 4 is sleeved on the outer wall of the B sleeve 400 through the spiral slide rail 401 , when the B turntable 4 rotates with the central axis 10 and can slide along the spiral slide rail 401, the outer circumferences of the A turntable 3 and B turntable 4 are on the same horizontal line and the outer diameters of the two disks are the same, and A The turntable 3 and the B turntable 4 are rotatably installed in the arc e...

Embodiment 3

[0033] The difference between the third embodiment and the first embodiment is that in the present invention, the combination figure 1 , Figure 6 and Figure 8 The protruding ring 302 is used to replace the annular convex rail 31, and the protruding ring 302 is provided on the edge of the A turntable 3 and away from the side of the B turntable 4, that is, the convex ring 302 is arranged on the left edge of the A turntable 3. Ring 302, the convex ring 302 is rigid or elastic, and the short side end of the L-shaped rotating rod 50 is sequentially connected to the convex ring 302 provided on the A rotary disk 3 through the compression spring 54, the sleeve cap 51; The protruding ring 302 is provided with a recessed point 303, and the recessed point 303 is arranged near the placement groove 30 for placing the gas pellets that is finally triggered on the A turntable 3. When the last gas shot in the placement groove 30 of the A turntable 3 After the pill is triggered, the concave...

Abstract

The invention discloses a double-turntable spring type arc extinguishing lightning protection device. The arc extinguishing lightning protection device comprises an arc extinguishing lightning protection shell, an arc extinguishing cylinder, a turntable A, a turntable B and a driving switching device, wherein a rotatable central shaft is horizontally arranged in the arc extinguishing lightning protection shell; the turntable A and the turntable B are arranged on the central shaft in a sliding manner; a plurality of placing grooves for placing air pills in the radial direction are uniformly formed in the circumferential side walls of the turntable A and the turntable B; the arc extinguishing cylinder is in contact with the placement groove in the turntable A or the turntable B; a supportingpoint is arranged at the top end of the inner side wall of the arc extinguishing lightning protection shell close to one side of the turntable B; volute spiral springs are arranged in the centers ofthe interiors of the turntable A and the turntable B respectively; and the driving switching device is in transmission connection with the turntable A and the turntable B respectively. Thud, dislocation movement of the arc extinguishing cylinder in the turntable switching process is avoided, and the reliability of double-turntable switching is improved.

Description

technical field [0001] The invention belongs to the technical field of lightning protection and arc extinguishing, and in particular relates to a double-disk clockwork type arc extinguishing and lightning protection device. Background technique [0002] Lightning protection of transmission lines has always been an important part of the lightning protection work of the power sector, and lightning faults are still one of the important factors affecting the safety of the power grid. The impact flashover caused by lightning strike on the transmission line will cause the line insulator to flash over, and then generate a large power frequency continuous current, damage the insulator string and fittings, and cause a line accident. In this regard, the power sector generally adopts the installation of line lightning arresters on transmission lines to achieve protection. The lightning arrester is an electrical device that can release lightning or overvoltage energy in the power syste...
