Product Description

Product Introduction:

Transformer Comprehensive Test Bench can truly determine the no-load current, no-load loss, impedance voltage, and load loss of power transformers, accurately measure the DC resistance and turns ratio of power transformers, implement condition diagnosis, ensure safe operation, and provide reliable data for monitoring or repairing transformers. The Transformer Comprehensive Test Bench is suitable for power supply and distribution systems, power transformer manufacturers, industrial and mining enterprises, and other units.

Transformer Comprehensive Test BenchProduct Features:

1. Transformer no-load, load, DC resistance, turns ratio and polarity tests.

◇ Transformer no-load, load, DC resistance, turns ratio and polarity tests are completed through the industrial computer.

◇ The Transformer Comprehensive Test Bench provides comprehensive control and measurement monitoring of the entire circuit.

◇ The measured data is automatically processed by the computer and can be stored and printed as needed.

2. Power frequency withstand voltage test

◇ Since this test is a safety regulation high-voltage test, to ensure the safety of test equipment and personnel, this test is not completed through the industrial computer.

◇ An electric control voltage regulation system is adopted. Automatic voltage rise and fall, digital display.

◇ Zero position protection, overcurrent protection, overvoltage protection.

◇ High-voltage leakage current display and protection.

3. Induced overvoltage withstand test

◇ Since this test is a safety regulation high-voltage test, to ensure the safety of test equipment and personnel, this test is not completed through the industrial computer.

◇ A 150Hz medium-frequency generator set provides the test power supply.

4. The transformer comprehensive test system consists of four parts

◇ The transformer comprehensive test bench used for each test unit and instrument monitoring data collection.

◇ Low-voltage control cabinet.

◇ Medium-frequency generator set.

◇ Power frequency withstand voltage test.

5. The transformer comprehensive test bench consists of four major parts

◇ Industrial computer and data processing software system.

◇ Data collection system for each test unit.

◇ Power control and instrument monitoring system.

◇ Human-machine interface comprehensive system.
