    摘要: The application provides an electrical system with online sampling and check function and its check method for high-voltage and medium-voltage electrical equipment, including electrical equipment, gas density relay, gas density sensor, valve, pressure regulating mechanism, online check contact signal sampling unit and intelligent control unit. The pressure is increased or decreased by the pressure regulating mechanism to enable the contact action of the gas density relay of electrical equipment. The contact action is transmitted to the intelligent control unit through the online check contact signal sampling unit. The intelligent control unit detects the alarm and/or blocking contact signal operating value and/or return value according to the density value of the contact action; the check of the gas density relay can be completed without maintenance personnel on site, which greatly improves the reliability of the power grid and the work efficiency, and reduces the O&M cost. At the same time, it also realizes the mutual self-inspection between gas density relay and gas density sensor, and further realizes the maintenance-free.

    摘要: A gas density relay check device and a check method thereof are provided. In check, a temperature adjusting mechanism and a gas density relay are relatively set. Temperature rise and fall of a temperature compensation element of the gas density relay is adjusted through the temperature adjusting mechanism, then the gas density relay is enabled to have a contact signal action. A gas density value is obtained according to the pressure value and the temperature value in the contact action. A contact signal operating value of the gas density relay is detected to check on the contact signal operating value of the gas density relay. The gas density relay check device of the present disclosure is capable of accurately checking gas density relays, and is particularly applicable to a gas density relay without a three-way valve, and check can be achieved without disassembling the gas density relay.
