Pilot test with thermal calibrator, easy to operate on a single machine. The stand-alone machine is operated by a convenient and flexible rotating mouse through a large-screen LCD monitor, all LCD monitors are displayed in Chinese. It can complete most of the field test verification work, verify various relays and microcomputer protection, and simulate various complex transient and switching faults for the entire test group. It can be used after booting, and the operation is convenient and quick.

The dual operation mode runs in connection with the computer. Through the full set of Chinese operating software on the windows platform, various large-scale, complex and highly automated calibration work can be performed, easily test and scan various protection settings, store test data in real time, display vector diagrams, and draw fault waveforms. Print reports online, etc.

The software has powerful functions, and can complete various large-scale, complex and highly automated calibration tasks such as three-phase differential test, fast switching of factory power, standby automatic switching test, line protection detection, and synchronous reclosing. Test and scan various protection settings, perform fault playback, store test data in real time, display vector graphics, print reports online, etc.

There are abundant switch contacts, including 7-way contact input and 2 pairs of empty contact output. The input contacts are empty contacts, compatible with 0~250V potential contacts, and can be intelligently recognized automatically. Input and output contacts can be expanded according to user needs.

The large-screen LCD is a 320×240 dot-matrix large-screen high-resolution graphic LCD. All operating procedures are set on the display. The operation interface and test results are displayed in Chinese, which is intuitive and clear.

Self-protection adopts a reasonably designed heat dissipation structure, with reliable and complete multiple protection measures, soft start of the power supply, and certain fault self-diagnosis and blocking functions.

There is an independent dedicated DC power output device, and all the way 110V, 220V dedicated adjustable DC power output.

The cost-effective thermal calibrator for high school test control is an interdisciplinary joint design product that integrates multi-disciplinary advanced scientific and technological achievements. It combines the performance of a large tester with the price of a small tester, and has a high cost performance.

Test procedure for thermal calibrator:

1. Disconnect the gas circuit of the thermal calibrator of the device under test from the gas circuit of the device body.

2. Cut off the power supply of the thermal calibrator control circuit of the equipment under test.

3. Connect the node socket of the thermal calibrator to the corresponding node of the thermal calibrator under test.

4. Connect the gas path connection part of the thermal calibrator to the gas path of the thermal calibrator under test.

5. Adjust the pressure of the storage tank of the thermal calibrator to achieve the alarm or locking pressure of the thermal calibrator under test.

6. For equipment equipped with a pressure gauge at the same time, when checking the alarm or locked action value or return value, the indicated value of the pressure gauge can be recorded at the same time, and compared with the pressure value given by the thermal calibration instrument (in addition, it can be Add 2-4 different pressure values ​​as needed), each pressure gauge should be calibrated at 5~8 points.

7. Record the action value or return value of the thermal calibrator when it reaches the alarm or lock (the recorded value should be corrected to the pressure value at 20°C).
