When we come into contact with the SF6 gas density relay calibrator, we want to know what its function is and what power equipment is it used to test?
Before the introduction, let's take a look at the SF6 switch. The SF6 switch is a high-voltage electrical appliance that is widely used in power systems. Its reliable and stable operation is one of the issues that the power supply department is very concerned about. As a result, the SF6 gas density relay begins to play its role.
1. The role of SF6 relay
The main function of the SF6 gas density relay is to monitor the change of the SF6 gas density in the SF6 switch during operation. The test personnel mainly determine the alarm value, blocking value, alarm recovery value, safety of SF6 switches, and blocking recovery value of the SF6 gas density relay by measuring the data. It can be seen that the performance of the SF6 relay directly affects the operation safety of the SF6 switch.
Due to the infrequent action, the SF6 gas density relay operating on site will often experience inflexible action and poor contact after a period of time, and some will have poor compensation performance. When the ambient temperature changes suddenly, it is often easy to cause the malfunctioning of SF6 relay.
Therefore, the unit using the SF6 switch should regularly check the SF6 gas density relay. From the perspective of safe use of electrical equipment, it is very necessary to regularly check high-voltage electrical appliances.
SF6 gas density relay calibrator is an intelligent calibration instrument. It is precisely because the calibrator adopts a high-precision pressure sensor and a high-speed A/D converter, combined with a 32-bit high-performance microprocessor, so as to perform performance verification on various SF6 gas density relays, and can accurately measure the the pressure value at the current temperature when the SF6 switch signal is actuated makes the test more accurate and more stable.
Because of the intelligent processing of electronic digitalization of the SF6 gas density relay calibrator, the SF6 gas density relay calibrator can automatically complete the conversion of any ambient temperature to the standard pressure at 20 °C. This tester is ideal for practical and reliable use in the power supply sector.
In addition, the SF6 relay also has the functions of printing, storage and U disk dumping, and can automatically identify faults during the test process.
The SF6 gas density relay calibrator greatly improves the work efficiency for electric power workers in the power supply department, reduces potential safety hazards, and also well reflects the intelligent characteristics of the SF6 gas density relay calibrator.
