Sulfur hexafluoride breaker inflation universal connector

Abstract

The invention discloses a sulfur hexafluoride breaker inflation universal connector which is mainly composed of a kit body, an air pipe, a pressure gage and valves. The air pipe is fixed on a bottom plate of the kit body and provided with a plurality of air holes communicated with one another, the air holes are formed outside the kit body, the valves are mounted on the air pipe and close to the air holes respectively, and the pressure gage is fixed in the bottom plate of the kit body and communicated with the air pipe. The sulfur hexafluoride breaker inflation universal connector has the advantages that air hoses with different calibers are clamped in one tool kit in a centralized mode, and through cooperation with the air pipe with the air holes, the universal connector meets the requirements of air holes of different manufacturer devices. The universal connector is simple in structure, low in manufacturing cost, convenient to use, and capable of meeting the requirements of air connection of air holes with different diameters.

Description

technical field [0001] The invention relates to the technical field of universal joints, more specifically to the technical field of universal joints for gas. Background technique [0002] In power equipment, high-voltage circuit breakers are one of the important equipment in the power system. They play a role in control and protection in the power grid. When the system fails, it can cooperate with the protection device and the automatic device to quickly cut off the fault current, prevent the accident from expanding, and ensure the safe operation of the system. Due to the large current, arc will be generated when the high-voltage circuit breaker operates. Therefore, sulfur hexafluoride is injected into the high-voltage circuit breaker to achieve the purpose of arc extinguishing and insulation. Or when the equipment is overhauled, it is often necessary to add sulfur hexafluoride gas to the equipment, and when the gas is added, because the size of the gas inlet of the equipm...

Problems solved by technology

Due to the large current, arc will be generated when the high-voltage circuit breaker operates. Therefore, sulfur hexafluoride is injected into the high-voltage circuit breaker to achieve the purpose of arc extinguishing and insulation. Or when the equipment is overhauled, it is often necessary to add sulfur hexafluoride gas to the equipment, and when the gas is added, because the size of the gas inlet of the equipment produced by each manufacturer is inconsistent, the staff is doing gas filling. Sometimes, it is often time-consuming and labor-intensive to find a suitable interface due to the size of the gas interface, which not only brings a lot of trouble to the work, greatly reduces the work efficiency, but also affects the development of other related work
