Description

Technical Field

[0001] The present application relates to the technical field of power systems, and in particular to a device, method, electronic device and storage medium for detecting the operating status of a circuit breaker energy storage motor. Background Art

[0002] Vacuum circuit breakers are key devices used to control and protect high-voltage circuits in power systems. They use vacuum interrupters to disconnect and close circuits, thereby ensuring the safety and stability of power systems. As part of the operating mechanism of vacuum circuit breakers, energy storage motors are responsible for providing the necessary energy for closing operations. With the continuous development of power systems, the reliability requirements for vacuum circuit breakers are getting higher and higher. Therefore, it is particularly important to effectively detect the operating status of energy storage motors.

[0003] In the existing technology, the energy storage motor of the vacuum circuit breaker usually adopts manual and electric energy storage methods. The energy storage motor stores energy by compressing the spring of the closing mechanism for emergency use. However, due to the lack of effective detection methods, the performance degradation and potential failures of the energy storage motor are often difficult to detect in time, which may cause the circuit breaker to fail to work properly at a critical moment, affecting the safe operation of the power system.

[0004] At present, traditional detection methods mainly rely on regular power outages for routine maintenance, which is not only inefficient but also unable to achieve real-time monitoring of the performance of energy storage motors. As users' requirements for power supply reliability increase, the number and duration of power outages for maintenance are strictly limited, making it increasingly difficult for traditional detection methods to meet actual needs. In addition, existing detection technologies can often only provide limited performance parameters, such as voltage and current, and cannot fully evaluate the operating status of energy storage motors, resulting in that even if detection is performed, it is difficult to accurately determine whether the motor has performance degradation or potential failures. Therefore, it is necessary to develop a new type of detection device that can address the shortcomings of existing detection technologies.

In addition, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context of the specific embodiment.

[0049] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0051] The operating mechanism of the 10kV and above high-voltage vacuum circuit breakers installed in the substation has manual and electric energy storage modes. The energy storage switch controls the start and stop of the energy storage motor. The function of the energy storage motor is to drive the energy storage mechanism to compress the spring of the closing mechanism, so that the closing mechanism spring produces a certain amount of compression energy, and the energy storage motor stops working and is ready for use when closing and tripping is required.

[0052] At present, the working status of circuit breakers is mainly judged through regular power outages and routine maintenance. However, as users' requirements for power supply reliability continue to increase, the number of power outages for maintenance is becoming less and less. The current routine power outages and maintenance are far from meeting the requirements for circuit breaker status judgment.

[0053] Abnormal defects in the electric energy storage of circuit breakers frequently occur in substations.

After correctly setting the system parameters, click the "Test Start" button in the software, and the system will automatically collect test data (time, voltage, current, power) until the data collection is automatically completed. The test terminates if any of the following conditions are met:

[0119] (1) If the device is abnormal (power failure, main circuit failure, output over-voltage or under-voltage, over-temperature), the test shall be terminated.

[0120] (2) When the test time reaches the "test time setting" value, the test ends.

[0121] (3) In the late stage of the test (after 10 seconds), the test current is 0, which means that the energy storage is complete and the test is terminated.

[0122] (4) In the later stage of the test (after 10 seconds), if the test current continues to be greater than 80% of the current value output by the driving power supply, the motor is judged to be faulty (severely overloaded) and the test is terminated.

[0123] (5) Click the “Manual Stop” button in the software to manually stop the test.

[0124] Maintenance personnel can read the voltage, current, power values ​​or test results to compare with the original parameters of the motor, whether the power consumption has increased, how long energy storage is required, and determine whether the motor performance has a downward trend.

[0125] Compared with the prior art, the circuit breaker energy storage motor operating status detection device provided in this embodiment has developed a dedicated drive power supply for the energy storage motor, a programmable output voltage, and automatically gives the motor a three-stage working electric expansion test with a current of 0-9A. It has complete over-current, over-temperature, and short-circuit protection functions to ensure that the power supply and equipment will not be accidentally damaged.

[0126] At the same time, the problem of detecting the comprehensive parameters of the energy storage motor has been solved.

It can accurately, quickly and quantitatively judge the operating status and reliability prediction of the energy storage motor, discover the trend of motor performance degradation in advance, and reduce the failure rate of the energy storage motor.

[0127] In addition, it is also possible to test the harmonic components of the voltage and current carrier waveform of the energy storage motor. By analyzing the driving harmonics and quantifying them in true effective values, it is possible to more comprehensively determine whether the motor has soft faults such as leakage, magnetic leakage, local short circuit, corrosion, etc., including whether the auxiliary action mechanism of the circuit breaker is normal, thereby more comprehensively detecting the operating status of the circuit breaker energy storage motor.

Then, by comprehensively analyzing multiple operating parameters, it can comprehensively evaluate the operating status of the energy storage motor, avoiding the limitation of relying on a single parameter. Finally, by comparing and analyzing real-time performance indicators and historical data, it helps maintenance personnel to judge the changing trend of motor performance, thereby achieving preventive maintenance and reducing the occurrence rate of failures. It can be seen that the present embodiment can effectively improve the real-time, accuracy and comprehensiveness of energy storage motor detection, thereby ensuring the safe and stable operation of the power system.
