Description

Technical Field

[0001] The present invention relates to the technical field of data storage, and more particularly to a data storage method for non-contact detection of the opening and closing speeds of high-voltage circuit breakers. Background Art

[0002] The opening and closing speeds of high-voltage circuit breakers are one of the important factors affecting the breaking performance of circuit breakers. If the opening and closing speeds are too fast, the operating mechanism and various transmission components of the circuit breaker will exceed the mechanical force they can withstand, causing damage to the buffer and shortening the service life of the circuit breaker. If the opening speed is too slow and it cannot quickly cut off the normal operating current or fault current, the arcing time between the contacts will be prolonged, resulting in hazards such as contact burning or even explosion of the arc extinguishing chamber. If the closing speed is too slow, when the circuit breaker closes on a short-circuit fault, it may not be able to overcome the action of the contact closing electrodynamic force, thus causing contact vibration or movement stagnation, and then resulting in contact burning or explosion of the arc extinguishing chamber. All along, the speed measurement of high-voltage circuit breakers has long been regarded as a difficult point in the field of circuit breaker mechanical characteristic testing. Existing speed measurement sensors are all contact sensors. However, in recent years, due to the increasingly compact design of high-voltage circuit breakers and GIS combined electrical appliances, their volume has become smaller and smaller, and the integration degree has become higher and higher, making the positions for previous speed measurement of high-voltage circuit breakers designed to be narrower and narrower, and it is not convenient to install the speed measurement sensors and fixed brackets or there is no place to install them. Therefore, the non-contact laser speed measurement technology can well solve the above problems. Its theoretical basis is that when a laser irradiates an object and undergoes diffuse reflection, the speed and position changes of the reflected light can be detected through the reflected light detection module. After the displacement is converted into an electrical signal by the reflected light detection module and output, the speed measurement of the object is completed. However, in reality, due to the need to detect high-voltage circuit breakers for a long time and the conversion between different data involved in the detection, the requirements for data storage are extremely high, which greatly increases the hardware investment. And as the data continues to increase, it is extremely difficult to maintain, making the practical application of non-contact opening and closing speed detection of high-voltage circuit breakers have certain resistance. Therefore, there is an urgent need to design a new data storage technology to provide assistance for the application of non-contact laser speed measurement technology in the detection of the opening and closing speeds of high-voltage circuit breakers. Summary of the Invention

[0003] To solve the above problems, the present invention provides a data storage method for non-contact detection of the opening and closing speeds of high-voltage circuit breakers.
