The invention discloses a one-key sequential control support system for a substation switch cabinet and an application method thereof. The one-key sequential control support system includes a distance measuring unit, a central processing unit, a signal output unit and a motor drive unit, and the distance measuring unit includes The distance measuring sensor at the working position of the handcart, the distance measuring sensor at the test position of the handcart and the reflector, the reflector is installed on the contact arm of the handcart, the distance measuring sensor at the working position of the handcart, the distance measuring sensor at the test position of the handcart are installed and arranged in the substation switch The top of the circuit breaker room of the cabinet and when the handcart arm is in the working position, the reflector is arranged opposite to the distance measuring sensor in the working position of the handcart, and the reflector is arranged opposite to the distance measuring sensor in the test position of the handcart when the arm of the handcart is in the test position . The invention can effectively support the one-button sequence control of the handcart in the high-voltage switch cabinet of the smart substation, the smart substation and the conventional substation, and provide the position information of the handcart and the handcart that are not homologous with the electrical auxiliary contacts for the one-key sequence control operation of the substation remote control.
Description
technical field [0001] The invention relates to a switching operation technology of a substation switch cabinet, in particular to a one-key sequential control support system for a substation switch cabinet and an application method thereof. Background technique [0002] With the continuous advancement of power grid construction, the number of substations is increasing, and the workload of operation and maintenance personnel is increasing rapidly, especially the high safety risk and heavy operation workload of substation switching operation. In order to reduce the pressure of power grid operation and maintenance personnel and improve the safety of substation switching operations, researchers developed a “one-key sequence control” system for switching off switches, which uses software and hardware technology to realize automatic execution of substation switching operation procedures, and operation and maintenance personnel only provide assistance. confirm. The smooth executio...
