The transformer direct resistance to transformer ratio comprehensive tester is a specialized equipment used for testing transformer parameters. It is mainly used to test parameters such as DC resistance, transformation ratio, and winding grounding resistance of transformers. Its application and product advantages include:
Product application:
1. Test Transformer DC Resistance: Test the DC resistance of the transformer winding to determine whether the winding joints are in good condition and whether there are short circuits or open circuits in the winding.
2. Test transformer ratio: By testing the transformer ratio, it is possible to determine whether the transformer has an accurate transformer ratio or tap position, thereby ensuring the stability and reliability of the transformer's transformer performance.
3. Test winding grounding resistance: Test the grounding resistance of the winding to determine whether the insulation is normal and whether there are grounding faults or other issues.
4. Data recording and analysis: The tester can record and save test data, provide detailed analysis and reports, and facilitate users to evaluate and manage the condition of transformers.
Product characteristics:
1. Powerful: capable of testing line resistance, phase resistance, and transformer ratio groups;
2. Testing efficiency: With one connection, the high-voltage side line resistance, low-voltage side line resistance, low-voltage side phase resistance, and transformation ratio can be tested, and the entire process is fully automated without manual intervention;
3. The instrument integrates a three-phase independent power amplifier with stable amplitude and adjustable phase for ratio testing, which can flexibly output single-phase, two-phase, and three-phase voltages;
4. Integrated high-power controllable constant current power supply for direct resistance testing, supporting 7 current output gears, ZUI high output 10A current;
5. Not only suitable for general power transformers (Y-type, D-type, Z-type), but also suitable for Scott, inverse Scott, and balance transformer testing of rectifier transformers and railway electrical systems.
6. The instrument automatically calculates the three-phase transformation ratio error, three-phase resistance imbalance, etc., and can automatically convert the temperature of the direct resistance;
7. The instrument has overcurrent protection and reverse line protection functions for high and low voltage connections inside;
8. The internal range of the instrument automatically switches based on the tested object; The test is completed with audio prompts for the discharge process;
9. 320x240 large screen, high brightness LCD display, full Chinese menu and operation prompts for friendly human-machine dialogue, touch buttons for easier operation;
10. Equipped with a real-time electronic clock, it automatically records the date and time of the experiment, which is conducive to the storage and management of experimental results;
11. The data has power down storage and browsing functions, can store 1000 sets of experimental results, and can be transmitted online with a computer;
12. The test results can be automatically uploaded to the server or the manufacturer's ERP system;
In summary, the transformer direct resistance to transformer ratio comprehensive tester has product advantages such as versatility, high precision, automation, data processing function, and portability. It is widely used in the power industry, maintenance management, and other fields, and can meet users' needs for transformer parameter testing, improving testing efficiency and accuracy.
