The generator rotor AC impedance tester is a specialized instrument used to test the impedance of the generator rotor. It can measure the AC impedance and characteristic curve of the generator rotor winding under dynamic and static conditions, and is an important tool for determining whether there is a turn to turn short circuit in the generator rotor winding. The following is a detailed introduction to the tester:
1. Product Overview
Generator RXRotor AC Impedance Testing Instrument, abbreviated as AC Impedance Testing Instrument, is a generator rotor ac impedance tester. The tester has been improved and enhanced, and an enhanced AC impedance tester has been launched, using the "one click shuttle" technology (rotating the mouse) for more convenient operation. It can not only measure the AC impedance of the generator rotor, but also measure the AC impedance of various synchronous and asynchronous motor windings.
2. Main functional features
Comprehensive measurement parameters: The tester can automatically collect, measure, display, store, and print all measurement parameters, including voltage, current, impedance, power, frequency, etc.
Easy to operate: Using rotating mouse technology makes the operation more convenient and efficient. At the same time, a large screen Chinese menu interface is provided to display test data and curves in real-time.
There are various measurement methods: quick automatic measurement and arbitrary manual measurement can be selected to meet different testing needs.
Strong data processing capability: The tester is equipped with a built-in data processing unit, which can analyze and calculate the test results, and obtain the impedance characteristics of the rotor, including geometric shape and electrical characteristics.
Security protection: The tester has an automatic protection function, which can automatically adjust the protection action value according to the test parameters to ensure equipment safety.
3. Working principle
The working principle of the generator rotor AC impedance tester is to inject electrical signals into the rotating rotor using the tester, and analyze the impedance characteristics of the rotor in the detected feedback signal. The tester includes a stator, control circuit, and data processing unit. Among them, the stator part is installed on the generator, the control circuit is responsible for outputting electrical signals and processing feedback signals, and the data processing unit is used to display test results.
4. Technical indicators
AC impedance: The test range is usually 0-99.999 Ω, with high accuracy.
AC voltage: The testing range is generally 0-600V, with high accuracy.
AC current: The testing range is wide and can meet different testing requirements.
Active power: The test range is large and can measure the rotor of a generator with high power.
Frequency: The testing range is usually 45-75Hz, suitable for generators of different frequencies.
Working power supply: generally 220V ± 10% 50Hz AC power supply.
5. Application scenarios
Generator rotor AC impedance tester is widely used in generator maintenance and repair work in power systems. By testing the impedance of the generator rotor, possible faults such as inter turn short circuits in the rotor winding can be detected in a timely manner, providing strong guarantees for the safe operation of the generator.
6. Precautions for use
Before conducting the test, it should be ensured that the connection between the tester and the tested generator is correct and reliable.
During the testing process, it is necessary to strictly follow the operating procedures of the tester to avoid equipment damage or inaccurate test results caused by misoperation.
During the testing process, attention should be paid to observing the display data and curve changes of the tester, promptly detecting abnormal situations, and taking measures to deal with them.
After the test is completed, the power supply of the tester should be turned off in a timely manner, and the tester and its accessories should be properly stored.
In summary, the generator rotor AC impedance tester is a powerful and easy-to-use electrical testing equipment, which is of great significance for ensuring the safe operation of generators.
