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, temperature regulation mechanism, online check contact signal sampling unit and intelligent control unit. The temperature rise and fall of the temperature compensation element of the gas density relay is regulated through the temperature regulation 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 method monitors a vacuum interrupter for leakage or loss of vacuum. The vacuum interrupter includes a line side, a load side and separable contacts electrically connected therebetween. The line side has a line side voltage and the load side has a load side voltage. The method includes determining whether the separable contacts of the vacuum interrupter are intended to be open or closed, comparing the line side voltage to the load side voltage, and determining the leakage or the loss of vacuum when the separable contacts of the vacuum interrupter are intended to be open and when the load side voltage is within a predetermined amount of the line side voltage.

摘要： A sensor connecting unit includes a safety input for connecting with a sensor; a power supply that is controllable through a controllable power switch; and a first I/O processing unit and a second I/O processing unit being connected to each other through a reciprocal comparison communication channel. The first I/O processing unit and the second I/O processing unit are both connected through a measurement circuit to measure voltage, current or power between a reference input and the safety input, and connected to a safety bus. The first I/O processing unit informs the second I/O processing unit about switching off of the controllable power supply, the second I/O processing unit commands the first I/O processing unit to switch off the controllable power supply, and/or the second I/O processing unit measures an output of the controllable power switch to detect switching of the power switch.
