Audited Supplier sf6 Density relay calibrator/Sulfur hexafluoride density relay tester/Gas pressure calibrator
Product overview
SF6 gas density relay is an important component used to monitor SF6 gas density change in SF6 switch body. Its performance directly affects the safety of SF6 switch operation. SF6 gas density relays running in the field often have inflexivity and poor contact after a period of time due to infrequent action, and some also have poor temperature compensation performance of density relays. When the ambient temperature changes, SF6 density relays often misoperate. Therefore, DL/T596-2005 "Preventive Test Procedures for Power Equipment" stipulates that each SF6 switch user should regularly check the SF6 gas density relay. In actual operation, SF6 density relays and pressure gauges in field operation are also regularly checked.
KDJD-D density relay calibrator is an intelligent calibration instrument for SF6 gas density relay. The calibrator adopts high-precision pressure sensor and high-speed A/D converter, combined with 32-bit high-performance microprocessor, can verify the performance of various SF6 gas density relays, can accurately measure the pressure value at the current temperature when the signal is operated, and automatically complete the standard pressure conversion of different ambient temperatures to 20ºC, and has the function of printing, storage and U disk transfer. At the same time, the fault in the test process is automatically identified. This product is convenient to carry, simple operation, high test accuracy, strong stability, good reliability, reflecting the "intelligent" characteristics of the instrument.
Instrument function
The main function of the instrument is to measure the alarm value, lock value, alarm return value and lock return value of SF6 gas density relay. The measurement process can be single lock measurement and double lock measurement. At the same time, the instrument has the function of normal temperature pressure gauge calibration and 20 degree pressure gauge calibration.

Product characteristics
1. High test accuracy: the core components are imported, with high integration, high precision and good repeatability.
High reliability.
2. Highly intelligent: the calibration process does not need a constant greenhouse, and can be used for SF6 gas in different effective temperature ranges
Density relays and pressure gauges are checked. The pressure and temperature dynamic compensation algorithm is used to automatically complete the pressure measurement and 20ºC equivalent pressure value conversion, and display the pressure at the current temperature and 20ºC equivalent pressure, which solves the difficult problem of SF6 gas density relay field calibration.
3. Powerful function: It can test a group of alarm signals and two groups of blocking signals at the same time, and has the function of normal temperature pressure gauge calibration and 20 degree pressure gauge calibration.
4. Friendly man-machine interface: Configure large-screen Chinese LCD screen and rotary mouse man-machine interface, simple operation and boundary
Beautiful appearance, all parameters and states are clear. The test process is automatically completed by the instrument, without manual intervention, avoiding cumbersome artificial gas path adjustment operations.
5. Supporting all transition joints: This product is a portable instrument, equipped with a variety of models of transition joints, most models of switch density relays can be on-site calibration without disassembly, is a common instrument for SF6 density relays calibration.
6. Low air consumption: very little air consumption in the verification process, no waste of SF6 gas, low test cost, no pollution.
7. Support data storage: built-in memory of the instrument, immediate storage of test results, with power down data storage power
Can query and print historical test data at any time.
8. Support report printing: Chinese character report type printing test results, and intelligent analysis of the test results.
9. Clock modification: Allows you to modify the system clock online.
10.U disk transfer: Support U disk transfer test data, read by PC, easy and fast operation.
11. Powerful PC software: Powerful PC application software, simple operation, data analysis, save, print and generate a complete test report, easy to centralized data management.
