    摘要： The application provides a modification of gas density relay, a gas density relay with online self-check function and its check method for high-voltage and medium-voltage electrical equipment. The gas density relay includes a gas density relay body, a gas density sensor, a pressure regulating mechanism, a valve, an online check contact signal sampling unit and an intelligent control unit. The pressure is increased or decreased by the pressure regulating mechanism to enable the contact action of the gas density relay body. 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 of the gas density relay body according to the density value of the contact action; the check of the gas density relay can be completed without maintenance personnel on site. It has remote reading function to realize free maintenance and significantly improve the reliability of the power grid and the work efficiency, as well as reduces the O&M cost.

    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 detector (100) that detects an alarm and/or fault condition with respect to a pressure of a medium is provided. The detector comprises a housing (102) comprising an access tube (104) configured to receive a medium and a bellows (108) fixed to the housing comprising a cavity (110) and a first contact surface (112). The detector also comprises an adjustment screw (114) positioned within the cavity of the bellows, coupled to the housing via an insulation member (120), and comprising a second contact surface (116). The detector is further configured to detect a change in pressure of the medium based on whether the first contact surface and the second contact surface are in electrical communication.

    摘要： A pneumatic pressure detector (12) for a fire alarm system (10) includes a housing (14) having an internal surface (18) defining an interior volume (20). Also included is an alarm switch (26) located within the interior volume (20) of the housing (14) and comprising a first deformable diaphragm (28) responsive to an increase in pressure of a gas disposed in a sensor tube (30) to indicate an overheat condition. Further included is an integrity switch (22) located within the interior volume (20) and comprising a second deformable diaphragm (24) disposed in contact with an electrical contact during pressurization of the gas within a predetermined pressure range and in an electrically open condition when the pressure of the gas is less than the predetermined range. Yet further included is a mica sleeve (34) located within the interior volume (20) of the housing (14) and disposed along at least a portion of the internal surface (18) of the housing (14) to insulate the alarm switch (26) and the integrity switch (22).
