Problems solved by technology
[0004] There is a contradiction between the volume of the device and the loading capacity of the existing wheel-type solid-phase arc-extinguishing lightning protection device. The number of gas pills installed inside the device is limited by the volume of the device. Therefore, a wheel-type solid-phase arc-extinguishing lightning protection device is proposed. The variable moving device of the arc extinguisher to solve the above problems

The invention discloses an arc extinguishing cylinder variable moving device of a wheel type solid-phase arc extinguishing lightning protection device, and belongs to the technical field of arc extinguishing lightning protection devices. The device comprises a shell, a turntable, a pressurizing gas pill and a rotating shaft, wherein the rotating shaft is arranged in the center of the turntable to drive the turntable to rotate, the shell is sleeved on the outer side of the turntable, the pressurizing gas pill is nested on the circular side edge of the turntable, a sliding groove is formed in the position, opposite to the circular side edge of the turntable, of the shell, an arc extinguishing cylinder is arranged in the sliding groove in a sleeved mode, and the arc extinguishing cylinder and the sliding groove are arranged in a relative sliding mode. According to the invention, the turntable with multiple layers of air pills is designed, so that the shot storage capacity of the device can be increased, the size of the device is not too large, and the maintenance period of the device is prolonged; and various gas pill switching modes are designed, and the arc extinguishing cylinder and the turntable are matched for switching, so that the reliability of movement between the arc extinguishing cylinder and the turntable can be ensured.
Description
technical field [0001] The invention relates to the technical field of arc extinguishing and lightning protection devices, in particular to a variable moving device for an arc extinguishing cylinder of a wheeled solid phase 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 freewheeling flow, 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 ...
