Resistance tester technical parameters - Database & Sql Blog Articles

Mechanical structure of arc-proof tester equipment 1. The main unit of the instrument is divided into upper and lower layers. The upper layer is the test chamber. The built-in test electrode system is closed with anti-UV organic glass door for easy observation and safety. There is ventilation hole on the experiment. , can automatically exhaust the wind.. Behind the inner panel of the laboratory, equipped with high-voltage circuit protection resistors and high-frequency suppression inductors. 2. The lower layer of the instrument is an electrical box. The right rear part is equipped with a high-voltage test transformer, and the right front part is pressure-regulated. The device and the step electrode boosting device, the front part is the main circuit control circuit and the single chip electronic circuit board. (To prevent interference, the circuit part separates the digital circuit from the analog circuit). The internal structure is shielded and isolated. 3. Test The transformer adopts dry type transformer, which has the advantages of good insulation performance, stable performance, low loss, no pollution, no maintenance, etc. The boosting device is adopted, and the stepping motor controls the voltage regulator to automatically boost. 4. The electromagnetic test will generate electromagnetic Interference, for better shielding and effect, all using isolation shielding technology for processing. Main technical requirements of arc resistance tester: 1, equipment input voltage: AC 220 V (common laboratory electricity Can be compatible) 2, test voltage mode: AC 0--100KV; DC 0--100 KV 3, electrical capacity: 10 KVA 4, test method: 0-100KV full range adjustable (using high-precision voltage sampling device, cancel The same kind of manufacturers must adopt high-voltage grading method because of insufficient voltage sampling accuracy. 5. Breakdown and withstand voltage test Boost rate: 500 V/S 1000 V/S 2500 V/S 5000 V/S 10000 V/S (This item Meet the latest standards in the extremely fast boost test requirements) Note: This product uses the most advanced DC servo motor loading mechanism to ensure the latest requirements for the extremely slow test and extremely fast test in the latest standard, to ensure that users can freely choose the boost The speed is the only test equipment in the same class that meets the national standard requirements for the boost rate. The appearance of this arc-resistant tester software is designed by professional artists: Personnel management: Multiple people can be added at the same time. Different people use this software to set different passwords to cross. Use without interference (such as one person can delete the setup password directly into the software) Parameter management: high voltage protection optional, withstand voltage time optional, gradient stepping optional, leakage current and Optional, sensitive leakage voltage optional, leakage current optional, boosting speed can be set freely (0-50kv free looping) test results can be selected for off-site operation selection, man-machine separation selection, etc. : The test results are saved and selected, the personnel selected and transferred, the test results can be arranged according to customer requirements, support more than 5 times of color line comparison, automatic adjustment and add test data. The arc resistance tester test is carried out at a higher voltage, so We design the necessary protective measures to prevent accidents. 1. The test is carried out in the test chamber. The sample can be placed in the air or in the transformer oil. The safe discharge distance of the 50KV voltage head is less than 200mm for all sides, even during the test. There is no danger of touching the wall of the box. 2. The high-voltage side end of the step-up transformer and the instrument casing are connected together, that is, the instrument casing and the ground at the location are equipotential. 3. Circuit protection: the instrument is provided with overcurrent Protection, overvoltage protection, voltage loss protection, short circuit protection, leakage protection circuit, etc. Main scope and function: The arc resistance tester is based on electrical plastics used in motors, electrical appliances and household appliances. Corrosion resistance performance evaluation of insulating materials such as resin glue and insulating varnish, mainly used for arc resistance test of solid insulating materials such as plastic, film, resin, mica, ceramic, glass, insulating oil, insulating varnish, cardboard, etc.; The test machine is controlled by computer to display the current experimental state and experimental time. After the experiment is over, the current experimental data is saved and can be printed. Standard experimental report.
