产品概述

The automatic SF6 density relay calibrator is an intelligent SF6 density relay calibrator. This instrument uses a high-precision pressure sensor and a high-speed A/D converter, combined with a 32-bit high-performance microprocessor, can perform performance verification on various SF6 density relays, and can accurately measure the pressure value at the current temperature when the signal is activated. The conversion of any ambient temperature to the standard pressure at 20°C is automatically completed, and the test data can be printed and stored for reference in real time, and faults in the test process can be automatically identified. This product is convenient to carry, simple to operate, high test accuracy, strong stability, and good reliability, which embodies the "intelligent" characteristics of the instrument.

F6 switch is a high-voltage electrical appliance widely used in power systems. The reliable operation of SF6 switch has become one of the most concerned issues of power supply departments. The SF6 gas density relay is an important element used to monitor the change of the SF6 gas density in the SF6 switch body during operation. Its performance directly affects the operational safety of the SF6 switch. The SF6 gas density relays operating on-site do not operate frequently. After a period of time, they often exhibit inflexible actions and poor contact contact. Some of the density relays have poor temperature compensation performance. When the ambient temperature changes suddenly, the SF6 density is often caused. The relay malfunctions. Therefore, DL/T596-1996 "Preventive Test Regulations for Power Equipment" stipulates: All SF6 switch users should periodically check SF6 gas density relays. From the actual operating conditions, it is also very necessary to periodically verify the SF6 density relays and pressure gauges in field operation.

Performance characteristics

1. This product uses 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-button shuttle) man-machine interface, simple operation, beautiful interface, and all parameters and status are clear at a glance.

3. Automatically complete pressure measurement and 20°C value conversion, thereby completing dynamic automatic compensation between pressure and temperature. It also displays the pressure at the measured ambient temperature, the pressure at the ambient temperature at 20°C, and the ambient temperature. Thoroughly solve the problem of difficult field calibration of SF6 gas density relay.

4. All testing processes are automatically completed by the instrument without manual intervention, which avoids tedious manual airway adjustment operations.

5. All-metal quick-plug connectors are used to effectively avoid the locking phenomenon of plastic connectors in low temperature environments.

6. The test results are printed as a report of Chinese characters, and the test results are intelligently analyzed.

7. It can store 50 sets of test results at the same time, and has a power-down data protection function, and the previous test results can be inquired and printed at any time.

8. There is no need for a constant temperature room during the calibration process, and the SF6 gas density relay and pressure gauge can be calibrated within any effective temperature range.

9. Equipped with various types of transition joints, the density relays of most types of switches can be verified on site without disassembly.

During the calibration process, the gas consumption is very small, SF6 gas is not wasted, the test cost is low, and it does not pollute the environment.

10. With the function of online modification of the system clock.

11. It has the function of online modification of system pressure, which can be modified on site.
