Product details
◆
The MEMD-2000 SF6 density relay calibrator uses high-precision pressure sensors and high-speed A/D converters, combined with a 32-bit high-performance microprocessor, to perform performance verification on various SF6 density relays. It can accurately measure the pressure value at the current temperature when the signal is activated, automatically convert the standard pressure at any ambient temperature to 20 ℃, and print and store test data in real time for reference. At the same time, it can automatically identify faults during the testing process. This product is easy to carry, simple to operate, has high testing accuracy, strong stability, and good reliability, reflecting the characteristics of the instrument being "intelligent".
SF6 switches are widely used high-voltage electrical appliances in power systems, and the reliable operation of SF6 switches has become one of the more concerned issues for power supply and consumption departments. SF6 gas density relay is an important component used to monitor the changes in SF6 gas density in the SF6 switch body during operation, and its performance directly affects the safety of SF6 switch operation. The SF6 gas density relay operated on site often experiences inflexibility and poor contact after a period of time due to infrequent operation. Some density relays may also have poor temperature compensation performance, which can lead to misoperation of SF6 density relays when the ambient temperature suddenly changes. Therefore, DL/T596-1996 "Preventive Testing Regulations for Power Equipment" stipulates that each SF6 switch user unit should regularly calibrate SF6 gas density relays. From the actual operating situation, it is also necessary to regularly calibrate SF6 density relays and pressure gauges during on-site operation.
◆ Product features of SF6 density relay calibrator
The density relay calibrator adopts a 32-bit microprocessor and TI's high-speed signal processing chip for detection and control, with a high degree of integration. Mechatronics design, high precision, good repeatability, and high reliability.
2. Equipped with a large Chinese LCD screen and a rotating mouse (one click shuttle) human-machine interface, the operation is simple, the interface is beautiful, and all parameters and statuses are clear at a glance.
3. Automatically complete pressure measurement and 20 ℃ value conversion, thus achieving dynamic automatic compensation between pressure and temperature. And display the pressure at the tested ambient temperature, the pressure at the ambient temperature of 20 ℃, and the ambient temperature. Thoroughly solved the problem of difficult on-site calibration of SF6 gas density relays.
4. All testing processes are automatically completed by instruments without manual intervention, avoiding tedious manual air circuit adjustment operations.
5. Print test results in Chinese character report format and perform intelligent analysis on the test results.
6. It can store 50 sets of test results simultaneously and has a power-off data protection function, which can query and print previous test results at any time.
During the verification process, no constant temperature chamber is required, and SF6 gas density relays and pressure gauges can be calibrated within any effective temperature range.
8. Equipped with multiple types of transition joints, most density relays for switches can be verified on-site without disassembly.
During the verification process, the gas consumption is minimal, SF6 gas is not wasted, the testing cost is low, and there is no pollution to the environment.
10. It has the function of online modification of the system clock.
11. It has the function of online modification of system pressure and can be corrected on-site.
12. The core components are imported and have reliable performance.
13. Can simultaneously test one set of alarm signals and two sets of lockout signals.
14. This product is a portable tool that is easy to use and reliable, making it a better choice for SF6 density relay calibration.
