Abstract

The invention discloses a disassembly-free verification type SF6 gas density relay and a use method thereof, and provides an SF6 gas density relay capable of performing gas density verification without dismounting a body device; the SF6 gas density relay comprises an SF6 density relay body, a wiring device and a joint device; the wiring device is arranged on one side of the SF6 density relay body,and the joint device is mounted on the other side of the SF6 density relay body; the wiring device is respectively connected with a plurality of related wires and the SF6 density relay body, the joint device is respectively connected with a related device of the SF6 gas density relay and the SF6 density relay body, and the SF6 density relay body, the wiring device and the joint device are integrally formed.

Description

technical field [0001] This application relates to the technical field of gas density calibration, in particular to a SF calibration without disassembly 6 Gas density relay and method of use. Background technique [0002] Sulfur hexafluoride, the chemical formula is SF 6 , is a colorless, odorless, non-toxic, non-flammable stable gas, SF 6 The gas density relay is used to detect SF in operation 6 SF in the electrical switch body 6 The change of gas density directly affects the performance of SF 6 Safe Operation of Electrical Switches, SF 6 Due to the infrequent action of the gas density relay, after a period of time, the action will be inflexible, the contact point will be poor, and sometimes there will be deviations in temperature compensation performance. When the ambient temperature changes suddenly, it will easily lead to SF 6 The gas density relay malfunctions, so it is necessary to check the SF 6 The gas density relay is periodically calibrated. [0003] Curren...
