The SF6 density relay calibrator may encounter some common problems during use. The following are some common problems and their solutions:
1. Hardware malfunction:
Problem: Sensor damage, air path blockage or leakage, etc.
Solution: Regularly inspect and calibrate the sensors to ensure their proper functioning; For issues of air blockage or leakage, it is necessary to clean or replace air components to ensure unobstructed air flow.
2. Software malfunction:
Problem: Program errors or system crashes, etc.
Solution: Update the software version to ensure that the program is up-to-date and stable; For system crash issues, you can try restarting the device or restoring default settings.
3. Environmental conditions impact:
Problem: Environmental factors such as temperature and humidity may lead to inaccurate test results.
Solution: Try to conduct testing in a relatively stable environment, such as using constant temperature and humidity equipment to control the testing environment; At the same time, regularly calibrate the calibrator to eliminate the influence of environmental factors.
4. SF6 gas moisture issue:
Problem: Moisture in SF6 gas may cause equipment failure.
Solution: Strictly control the moisture content in SF6 gas and use desiccants or drying equipment to dry the gas; At the same time, regularly check the moisture content in the gas to ensure it is within a safe range.
5. Operational issues during the verification process:
Problem: Improper placement of the verified density relay, incomplete discharge of residual gas, etc.
Solution: Ensure that the verified density relay is placed upright; After the experiment is completed, it is necessary to drain the residual gas in the pipeline before pulling out the trachea; At the same time, avoid using the rapid exhaust port of the calibrator during the testing process to avoid wasting the gas source.
6. Storage and transportation issues of calibration equipment:
Problem: Poor storage environment or vibration and impact during transportation.
Solution: Store the calibrator in an environment with suitable temperature, humidity, and no corrosive gases; During transportation, use specialized transport boxes for packaging and avoid severe vibrations and impacts.
In addition to taking corresponding solutions to the above problems, it is also necessary to strengthen daily maintenance and upkeep work, regularly inspect and calibrate the calibration instrument, and ensure that it is in good working condition. At the same time, operators should receive professional training to understand the working principle and operation methods of the equipment, in order to avoid equipment damage or personnel injury caused by misoperation.
The ZC-310 SF6 density relay tester is an intelligent SF6 gas density relay calibration instrument. The equipment adopts high-precision pressure sensors and high-speed A/D converters, combined with 32-bit high-performance microprocessors, which can perform performance verification on various SF6 gas density relays. It can accurately measure the pressure value at the current temperature when the signal acts, automatically convert the standard pressure at any ambient temperature to 20 ℃, and has printing, storage, and USB transfer functions.
