Abstract

The invention provides an isolating switch control system based on real-time state diagnosis and multiple anti-misoperation. The isolating switch control system comprises an information acquisition unit, a logic diagnosis unit, an anti-misoperation unit and a variable frequency driving unit, wherein the information acquisition unit is used for acquiring state information of an isolating switch in a motor control circuit, voltage information of a motor power supply circuit and current information during operation of a motor in real time, the logic diagnosis unit is used for determining opening permission state information and closing permission state information of the motor according to the state information of the isolating switch in the motor control circuit and a built-in opening and closing logic rule, the anti-misoperation unit is used for determining the state information of the power circuit breaker of the motor power supply circuit, and according to the state information, the opening permission state information, the closing permission state information, the voltage information and the current information of the power supply circuit breaker, determining whether opening operation and closing operation can be executed for the motor, and the variable frequency driving unit is used for controlling the operation state of the motor.

Description

technical field [0001] The invention relates to the technical field of electric power automation, in particular to an isolating switch control system based on real-time state diagnosis and multiple misoperation prevention. Background technique [0002] At present, the isolating switch with a voltage level of 110kV and above generally uses a motor operating mechanism, which realizes the opening and closing operation by controlling the AC power supply of the three-phase asynchronous motor, but the operating circuit of the open isolating switch is mainly composed of various relays, contactors, and switches. Discrete devices such as switches are built and connected. The number of components is large, the number of mechanical contacts is large, and the circuit structure is complex. In complex and harsh outdoor environments, failures such as component aging, loose wiring, poor contact, and mechanical jamming often cause isolation. The problem with the switch refusing to move. The...
