The embodiment of the invention discloses a connecting lever switching-on / off in-place monitoring system and method for a high-voltage switchgear. The system comprises a detection device, a server anda client side, wherein the detection device and the server are in communication connection; the server and the client side are in communication connection; the detection device comprises a columnar shell which comprises a round cake shaped chamber positioned on a central position, and a circular-ring-shaped chamber positioned on an edge position; a spherical moving object is arranged in the circular-ring-shaped chamber; an accelerometer, a communication element and a control element are arranged in the round cake shaped chamber; and the control element is independently in telecommunication connection with the accelerometer and the communication element; and the communication element and the server are in communication connection. The system is fixed on a transmission connecting lever through the shape structure of the detection device, and the system carries out relative movement under the function of self weight according to the movement of the spherical moving object along with thetransmission connecting lever, the detection device integrally moves along with the transmission connecting lever, so that a switching-on / off state is determined through the spherical moving object, and the specific state of monitored equipment can be known in time.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of high-voltage switchgear, and in particular to a system and method for monitoring the opening and closing position of the crank arm of the high-voltage switchgear. Background technique [0002] With the development of society and economy, people have higher and higher requirements for power quality, and the number of substations and their equipment has increased accordingly. Among them, circuit breakers, disconnectors and other switching equipment account for the majority of them, and their opening and closing operations are successful. The rate affects the normal operation of the power grid system, and even relates to the personal safety of operators and inspection personnel. Therefore, it is necessary to confirm the opening and closing status to avoid safety accidents caused by improper operation, and to further monitor the power supply network and equipment. demanding.
