Gravity driving type bomb replacing arc extinguishing device

Abstract

The invention discloses a gravity driving type bomb replacing arc extinguishing device which comprises a bomb storing bin (1) and an arc distinguishing cylinder (7). A triggering coil (11) and an arc guide fitting (10) are arranged in the bomb storing bin (1), the bottom of the bomb storing bin (1) is provided with an arc guiding electrode (9) and a gas pellet triggering position, and a side face electrode (6) is arranged on the side wall of the gas pellet triggering position. A spiral type gas pellet advance rail (2) which is arranged from top to bottom and used for bearing an arc extinguishing gas pellet (5) is arranged in the bomb storing bin (1). A gravity ball storing bin (15) is arranged on the top of the bomb storing bin (1), an opening of the gravity ball storing bin (15) is communicated with an inlet of the gas pellet advance rail (2), and a gravity ball (14) is arranged in the gravity ball storing bin (15). The gravity driving type bomb replacing arc extinguishing device is simple in structure, safe and reliable, the arc extinguishing pellet in the bomb storing bin can smoothly slide downwards only under the gravity action, and the process of exchanging a bomb after arc extinguishing is triggered is achieved.

Description

technical field [0001] The invention belongs to gas arc extinguishing and lightning protection protection equipment, and in particular relates to an arc extinguishing device which adopts gravity drive to change bombs. 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. The traditional "blocking" lightning protection method cannot fundamentally solve the lightning strike problem due to its limitations. Therefore, the power sector generally adopts the installation of parallel protection gaps or line arresters on the transmissi...

Problems solved by technology

These patents have achieved a good solution to the above problems, but the number of arc extinguishing gas pellets placed inside the arc extinguishing device in these protection devices is limited, resulting in a limited number of operations. If it is installed in a minefield, it is necessary to repair the arc extinguishing device Frequent replacement will greatly increase the maintenance cost; and if more arc extinguishing gas pills are to be placed in the arc extinguishing device of the current structure, in order to ensure the smooth progress of the bomb replacement, specific power components (such as coil springs) must be installed. etc.), which undoubtedly increases the complexity of the structure of the arc extinguishing device, and at the same time increases its maintenance cost to a certain extent
