100 Test: Principle and Application of High-voltage Switch Mechanical Characteristic Tester

High-voltage switch mechanical characteristic tester is a general-purpose computer intelligent test instrument developed for various high-voltage switches. High-voltage shutdown characteristic tester applies photoelectric pulse technology, single-chip computer technology and reliable anti-electromagnetic radiation technology, together with accurate and reliable speed/distance sensors, can be used for vacuum of various voltage levels, sulfur hexafluoride, less oil, and more Adjustment and measurement of mechanical parameters such as oil high voltage switches. The instrument has the advantages of convenient wiring, simple operation, and one-time (partial) operation to obtain all the data of the (partial) gate. And can print all the required data, fracture current waveform and moving contact movement curve, easy to analyze and save.

High-voltage switch mechanical characteristics tester performance and features: 1. The instrument uses a high stability device. Floating, large-area, digital filtering and other anti-jamming technologies. 2. The instrument is equipped with two kinds of displacement sensors, which are suitable for detecting high-voltage circuit breakers with different distances, speeds, and precision requirements. After different sensors are inserted, they will be automatically identified. The instrument can automatically recognize the operation of the high voltage circuit breaker (separation) gate and the reclosing operation, and automatically collect all kinds of data after the operation. The measurement calculation process is done automatically by the CPU. 3. The instrument has automatic identification ability and strong self-protection function to the high-voltage circuit breaker in the measurement of the wiring error and the operation of the wrong instructions and unsuccessful operation. 4. The instrument will display the sequence of the merging (separation) brakes and the actual closing time of each fracture. It provides the basis for the maintenance and commissioning of the three phases of the high voltage circuit breaker in different phases and in different phases of the same phase. The data is automatically displayed with 0.1 milliseconds of data. 5. For measuring the stroke and overtravel of the moving contact, as long as the sensor is installed on the fracture of any phase of the high-voltage circuit breaker, the trip and overtravel data of the three-phase fractures can be measured and calculated at the same time. The measurement accuracy is 1% second meters. 6. The power box provides 0 to 250V DC operating power to directly operate the high voltage circuit breaker. Applicable to electromagnetic control, hydraulic, spring energy storage and other DC control operating mechanism. 7. The instrument is small in size, light in weight, simple in operation and portable, especially suitable for field flow detection and on-site maintenance testing of substations. It is an indispensable tool for high-voltage circuit breaker production, inspection, maintenance and debugging.
