Embodiment Construction

[0038] Embodiment of detection system of circuit breaker spring operating mechanism:

[0039] The detection system of the circuit breaker spring operating mechanism such as figure 1 As shown, it includes opening pressure sensor, closing pressure sensor, calibration pressure sensor, signal acquisition unit, data processing unit, communication control unit and power supply module.

[0040] The opening pressure sensor is arranged in the opening energy storage spring tank and is used to collect the pressure curve of the opening spring during the working process.

[0041] The closing pressure sensor is arranged in the closing energy storage spring tank and is used to collect the pressure curve of the closing spring during the working process.

[0042] Calibrate the pressure sensor to realize the calibration of the opening pressure sensor and the closing pressure sensor. When the spring operating mechanism leaves the factory, the mechanism will be calibrated and debugged by adjust...

Abstract

The invention relates to a method and a system for detecting a spring operating mechanism of a circuit breaker, and belongs to the technical field of intelligent sensing of primary equipment. The detection method comprises the following steps: (1) taking data in a spring state fingerprint database as a training sample set; (2) establishing a neural network topology model; (3) initializing the speed and position of particles; (4) updating a network threshold value and a weight value; (5) training a neural network topology model by using the training sample set; (6) updating the speed and the position of the particle, judging whether an end condition is met or not, if the condition is met, obtaining an optimal weight value and an optimal threshold value to obtain a trained diagnosis model, and if the end condition is not met, repeating the steps (4) to (6); and (7) diagnosing and judging the curve data obtained in real time to obtain an evaluation result. The fault detection of the spring operating mechanism is realized according to the diagnosis model, and the problems that the spring fatigue state of the spring operating mechanism of the circuit breaker is difficult to monitor and the fault is difficult to diagnose in time are solved.

Description

technical field [0001] The invention relates to a detection method and system for a circuit breaker spring operating mechanism, belonging to the technical field of primary equipment intelligent perception. Background technique [0002] The spring operating mechanism has been widely used in high-voltage circuit breaker equipment with a voltage level of 110kV and above due to its advantages of small power supply capacity, simple principle, and long maintenance cycle. As an important part of the spring operating mechanism of the high voltage circuit breaker, the opening and closing springs directly determine the opening and closing speed of the circuit breaker, and have an important impact on the stability and safety of the circuit breaker. However, currently limited by the material and technological level, the springs in the operating mechanism tend to fatigue, jam or even break after a certain period of operation, causing great hidden dangers to the safe and stable operation ...
