AI Technical Summary
Existing in-situ calibration methods for SF6 concentration meters have low accuracy, and conventional calibration methods require disassembling the equipment, affecting normal operation, making it difficult to achieve high-precision in-situ calibration.
The in-situ calibration system using mixed gas measuring equipment includes a calibration gas chamber, an electro-proportional valve, calibration pipelines, a thermometer, a pressure gauge, and a control unit, as well as a host computer. By controlling the calibration gas chamber to different output pressure states, combined with measurements from the thermometer and pressure gauge, the host computer establishes a calibration curve to calibrate the SF6 concentration meter.
It achieves high-precision in-situ calibration of SF6 concentration meters, avoiding equipment dismantling and ensuring the normal operation of electrical equipment and measurement accuracy.
