Description

SF6 high-voltage switch air-supplementing and testing control device

Technical Field

The utility model relates to a high tension switchgear field, concretely relates to SF6 high tension switchgear tonifying qi and test control device.

Background

The density of SF6 gas on SF6 electrical equipment is expressed in terms of the pressure of SF6 gas after temperature compensation, i.e. in terms of the pressure value at 20 ℃. When SF6 gas leaks due to some reason, the pressure after temperature compensation drops and falls to an alarm pressure value, the relay outputs a pair of contact points (alarm signals), at the moment, the user is required to supplement gas to the equipment, and if the pressure continues to drop and falls to a locking action pressure value, the relay outputs another pair of contact points (locking signals) to lock a corresponding control system of the equipment, so that the safe operation protection of the electrical equipment is realized. When the equipment is filled with SF6 gas, when the gas filling rate exceeds the rated value, the density relay can also send out an overpressure alarm signal. The SF6 gas density relay is the same as other pressure gauges, alarm and locking values of the SF6 gas density relay can generate certain drift after being used for a period of time, and the alarm and locking values can generate larger errors due to aging and deformation of a temperature compensation material after being used for a period of time; in addition, the density relay contacts may not operate frequently, which may result in insensitive or failure of the contacts. The hidden trouble can cause the SF6 switch to cause serious accidents because the pressure in the body is reduced to an alarm or locking value due to gas leakage and the alarm or locking cannot be carried out in time. So the verification should be performed periodically.

When current high tension switchgear tonifying qi and testing arrangement are using, the sulfur hexafluoride gas holder need carry alone, bumps the gas holder easily when the test, and then influences the test procedure, causes certain danger, consequently needs a utility model to solve current problem.
