Description

Technical Field

[0001] The present invention relates to the technical field of gas detection, regulation and transportation, and in particular to an SF6 gas detection and automatic regulation and transportation device. Background Art

[0002] SF6 electrical products have been widely used in the power sector, industrial and mining enterprises, and have promoted the rapid development of the power industry. Ensuring the reliable and safe operation of SF6 electrical products has become one of the important tasks of the power sector. The SF6 gas density relay is one of the key components of the SF6 electrical switch. It is used to detect the changes in the SF6 gas density in the SF6 electrical equipment. Its performance directly affects the reliable and safe operation of the SF6 electrical equipment. The SF6 gas density relay installed on site is not often operated. After a period of time, it often has the phenomenon of inflexible operation or poor contact of the contacts. Some of them also have poor temperature compensation performance. When the ambient temperature changes, it is easy to cause the SF6 gas density relay to malfunction. Therefore, the SF6 gas density relay should be calibrated regularly. From the actual operation situation, regular calibration of the SF6 gas density relay on site is one of the necessary means to prevent problems before they happen and ensure the safe and reliable operation of power equipment.

[0003] The existing models of SF6 gas density relay calibrators on the market can calibrate SF6 gas density relays. There are two main types of SF6 gas density relay calibrators on the market, one is a manual calibrator and the other is an automatic calibrator. In principle, both calibrators use a gas pressure lifting device connected to the SF6 gas density relay to be tested through a pipeline, and then control the action of the gas pressure lifting device manually or through a software program to adjust the gas pressure rise and fall, so as to calibrate the SF6 gas density relay. This type of calibrator can solve the problems encountered in solutions 1, 2, and 3, but the following problems still exist: (1) For manual calibrators, it is difficult to ensure consistent measurement accuracy each time when adjusting the gas pressure lifting device because each person has different operating methods, speeds, and strengths; (2) When adjusting the gas pressure lifting device, a manual calibrator requires a certain amount of force to operate, which is difficult for the operator to operate. Moreover, if it is used for a long time, the operation efficiency is not high and the measurement accuracy is even more inaccurate; (3) The automatic calibrators currently available on the market can automatically control the gas pressure lifting device and adjust the gas pressure rise and fall, so that the SF6 gas density relay can be calibrated. However, the automatic calibrators currently available on the market cannot realize the function of detecting gas recovery. After each calibration of the SF6 gas density relay, the SF6 gas in the pipeline must be released, which is harmful to the air and human body and is not environmentally friendly. Moreover, the gas source is external. Each time it is used, an external gas cylinder must be carried and connected to the automatic calibrator through a pipeline. It must be removed after use. SF6 gas leakage may also occur during the removal process. Therefore, using this type of calibrator is troublesome, not environmentally friendly, and wastes manpower and material resources.

[0004] How to quickly regulate the SF6 gas according to the actual situation after the equipment is used, so that the SF6 gas can be transported to the appropriate location as needed, while ensuring the normal operation of the equipment, is a difficult problem that technical personnel in this field need to solve.
