TKRLC-8QYG Buchholz relay calibrator and Buchholz relay test bench is also called Buchholz gas relay calibrator, Buchholz gas relay tester and Buchholz relay detector. Buchholz relay
The calibrator is a tester device that specifically strives for the calibration and testing of gas gas relays. The Buchholz relay calibrator is a special gas gas used to verify the flow rate, volume and sealing pressure value of the Buchholz relay.
The detection and verification device for the verification of the pressure release valve of the body relay. The Buchholz relay calibrator is suitable for the calibration of more than 90% of the Buchholz relays in China.
The Buchholz relay, also known as the Buchholz gas relay, is a protection unit in an oil-immersed transformer, installed in the oil pipe under the transformer oil pillow.
TKRLC-8QYG Buchholz relay calibrator and Buchholz relay tester are dedicated gas relay pressure release valve calibrators for verifying the flow rate, volume and sealing pressure of Buchholz relays.
Prepared, the Buchholz relay tester adopts microcomputer control technology. The Buchholz relay tester detects high-precision pressure sensors. The Buchholz relay tester simulates the internal fault of the transformer.
The instantaneous blasting pulse pressure method of the tester calculates the flow rate value to achieve the detection action value of the heavy gas protection of the Buchholz relay. The Buchholz relay calibrator uses a precision container combined with the American MCC company.
TKRLC-8QYG Buchholz relay calibrator is suitable for more than 90% of domestic gas relays.
For electrical calibration, the Buchholz relay calibrator adopts touch-screen hype, and the test time is short. The Buchholz relay calibration device is widely used in coal mines and electric power enterprises. 1. The equipment is light and portable: the Buchholz relay calibration bench has the advantages of small size, light weight, easy to carry, simple operation, meeting the needs of field tests, saving equipment and large investment in the laboratory, etc.
；
2. A variety of flange changing heads: special design, easy to replace, stable measurement, Buchholz relay calibrator can be used for various specifications (Φ25, Φ50, Φ80 and other calibers) Buchholz relay
High precision and stable measurement;
3. Flow rate measurement (heavy gas measurement): The Buchholz relay calibrator adopts clever piping design, cooperates with flange changer, and uses precise calculation and experimental verification of pressure and flow rate algorithm, precise
The flow velocity measurement of various specifications of Buchholz relays can be completed, the measurement resolution has reached 0.1 m/s, and the repeatability is good;
4. Volume measurement (light gas measurement): Real-time accurate volume measurement is achieved through accurate pipeline calculation and a micro pressure sensor produced in the United States. The measurement resolution has reached 1 ml;
5. Sealing measurement: The Buchholz relay calibrator uses a reasonable piping design and layout, and uses an ultra-quiet air pump to simulate the pressure inside the Buchholz to test the sealing performance of the relay;
6. The equipment performance is stable: signal lines, power lines, and pneumatic pipelines are completely separated, and the layout of each module is separated, and the shielding is perfect, which fully guarantees the adaptability and reliability of the equipment to the field test environment
Sex
7. Touch operation, beautiful interface: 7-inch full Chinese color touch graphic operation interface, intuitive and simple operation, and the results can be viewed, analyzed and printed;
8. Short test time: The Buchholz relay calibrator adopts optimized design, and the flow rate detection time is reduced by more than half compared with similar domestic products.
