When selecting a high-voltage switch dynamic characteristic tester in substation testing, it is necessary to comprehensively consider factors such as switch type adaptability, testing accuracy and function, operational convenience and safety, as well as economy and service support. The following is a specific analysis:
1. Clearly define testing requirements and switch types
① Switch type: In substation testing, various high-voltage switchgear such as vacuum, SF ₆, oil high-voltage circuit breakers, GIS grounding knife switch, contactors, etc. are involved. The mechanical characteristics and testing requirements of different types of switches vary, so it is necessary to ensure that the tester can adapt and accurately test these devices.
② Test parameters: Pay attention to the key parameters that the tester can measure, such as opening and closing time, synchronicity, speed, stroke, bounce time, and amplitude. These parameters are crucial for evaluating the mechanical performance of switches.
2. Evaluate testing accuracy and functionality
① Time measurement accuracy: Time parameters are one of the important indicators for evaluating switch performance. When selecting a tester, attention should be paid to its time measurement accuracy to ensure that it meets or exceeds the requirements of relevant standards (such as ± 0.1ms).
② Speed and stroke measurement: The measurement of speed and stroke is crucial for analyzing the mechanical motion characteristics of switches. The tester should have high-precision speed and travel measurement capabilities, and support multiple sensor types (such as linear and rotary sensors) to adapt to different switch structures.
③ Functional scalability: Consider whether the tester has functions such as data storage, export, report generation, and linkage with PC software, in order to conduct more in-depth data analysis and trend prediction.
3. Focus on economy and service support
① Cost effectiveness: Choosing a cost-effective tester can reduce procurement costs while meeting testing requirements. However, it should be noted that low prices should not be pursued at the expense of the performance and quality of the testing equipment.
② After sales service: Choosing a supplier with a comprehensive after-sales service system can ensure timely resolution of any problems encountered during use. This includes technical support, maintenance, parts supply, and other aspects.
ZC-300B circuit breaker analyzer can be used to test and measure the mechanical characteristic parameters of high voltage switch ( such as vacuum, six fluoride, less oil, oil and other power systems. The measurement data is stable, strong anti-interference ability, can be in the 500KV level and below the power station to do experiments, wiring is convenient, simple operation, is the most convenient tool for high-voltage switch maintenance test.
