摘要： The application provides a gas density relay with online self-check function and its check method, including a gas density relay body, a first pressure sensor, a second pressure sensor, a temperature sensor, a gas chamber, a pressure regulating mechanism, an online check contact signal sampling unit and an intelligent control unit. The air path of the pressure regulating mechanism is connected to the gas pressure chamber and the second pressure sensor; Pressure rise and fall can be regulated through the pressure regulating mechanism to make the gas density relay body contact action. The contact action is transmitted to the intelligent control unit through the online check contact signal sampling unit. The intelligent control unit detects the action value and/or return value of the contact signal of the gas density relay body according to the density value when the contact acts, and completes the check work without requiring maintainer to go to the site for check. At the same time, because the pressure regulating mechanism is not connected to the SF6 gas path of the gas density relay body or electrical equipment, its sealing requirements are reduced, the reliability of the power grid is improved, and the manufacturing cost is reduced.

摘要： A high anti-vibration gas density monitor is provided, including a monitor enclosure, a signal control mechanism, and an indication value display mechanism independent from the signal control mechanism which are provided in the monitor enclosure. The signal control mechanism includes at least one corrugated pipe, a sealed compensation chamber, a signal generator, and a signal regulation mechanism. The corrugated pipe is perpendicular to a side wall of a control casing. The monitor enclosure includes an independent sealed compartment used to mount the indication value display mechanism. The sealed compartment is filled with anti-vibration oil, or is hermetically filled with gas. The indication value display mechanism includes a Bourdon tube, a base, an end holder, a movement, a pointer, and a dial.
