The invention provides a pressure node detection system and method of a hydraulic mechanism. The system is applied to the pressure node detection of a hydraulic disc spring mechanism, including: an automatic pressure relief module, a state judgment module, a compression measurement module and a central control module; the central control module The module controls the automatic pressure relief module to automatically release the pressure of the hydraulic disc spring mechanism to the pressure node to be tested; the state judgment module detects the conduction state of the pressure node to be tested in real time, and sends the conduction state of the pressure node to be tested to the central control module; The compression measurement module measures the spring compression of the hydraulic disc spring mechanism in real time, and sends the spring compression of the hydraulic disc spring mechanism to the central control module; the central control module is based on the spring compression of the hydraulic disc spring mechanism when the pressure node to be tested is turned on Determine the detection result of the pressure node to be detected. The pressure node detection system and method of the hydraulic mechanism provided by the invention can effectively improve the efficiency and accuracy of pressure node detection.
Description
technical field [0001] The invention belongs to the technical field of intelligent detection, and more specifically relates to a pressure node detection system and method of a hydraulic mechanism. Background technique [0002] As a high-voltage circuit breaker, the hydraulic disc spring mechanism is widely used in substations. The working principle of this mechanism is: the hydraulic oil stores energy by compressing the disc spring, and realizes the opening and closing of the circuit breaker by releasing the energy of the disc spring. Among them, the hydraulic disc spring mechanism is designed with multiple pressure nodes according to the actual working conditions, each pressure node corresponds to a specific pressure value, and each pressure value represents a specific pressure state of the mechanism. Each pressure node is connected in series in the control loop to realize the control of the secondary loop. [0003] At present, during the detection of pressure nodes, the ...
