Comprehensive analysis and application guide for transformer comprehensive test bench
The transformer comprehensive test bench is a specialized equipment that integrates multiple testing functions, mainly used for electrical performance testing of power transformers. The following is a detailed analysis of the transformer comprehensive test bench, including its characteristics, functions, technical parameters, safety measures, and precautions:
1. Product Features
① Strong comprehensiveness: The transformer comprehensive test bench integrates multiple testing functions such as no-load short circuit, transformation ratio, direct resistance, AC withstand voltage, and control, which can comprehensively test the electrical performance of transformers.
② High precision: Advanced testing technology and high-precision instruments are used to ensure the accuracy and reliability of test results.
③ Easy to operate: Equipped with a color display and a fully Chinese operating interface, it enables real-time monitoring and automatic completion of the entire experiment process, reducing operational difficulty.
④ Efficiency: The entire testing process is highly automated, greatly improving testing efficiency.
⑤ Convenient data processing: Supports automatic data storage and microcomputer printing, avoiding manual copying and recording processes, ensuring the authenticity and reliability of data.
2. Function Overview
① No load short-circuit test: used to detect parameters such as no-load loss and short-circuit loss of transformers.
② Ratio and group testing: Measure the ratio, group, and ratio errors of transformers to ensure the accuracy of voltage conversion.
③ DC resistance test: Measure the DC resistance of transformer windings to determine if there are any faults or poor contacts in the windings.
④ AC voltage withstand test: By applying high-voltage AC power, the insulation performance of the transformer is tested.
⑤ Control function: Integrated strong current control and instrument monitoring comprehensive system to achieve comprehensive control of the testing process.
3. Technical parameters
① Voltage range: generally up to 0-450V, with an accuracy of up to 0.1 level.
② Current range: usually 0~5A, some devices can support a larger current range, and the accuracy can also reach 0.1 level.
③ Measurement range: DC resistance testing can reach 0-2000 Ω, supporting multiple range selections.
④ AC voltage withstand test: The adjustable voltage range can reach 0~100KV.
⑤ Other parameters, such as resolution, accuracy, overall power consumption, operating temperature and humidity, all meet the requirements of high-precision testing.
4. Security measures
① Preparation before operation: Before use, it is necessary to carefully read the manual, and the operator should have general electrical knowledge.
② Environmental requirements: The use of the instrument should avoid places such as rain, corrosive gases, excessive dust, high temperatures, and direct sunlight.
③ Testing process: During the testing process, it is prohibited to move the testing clip and power supply line. After the testing is completed, wait for the discharge alarm sound to stop before turning off the power and removing the testing line.
④ Test of no-load tap changer: When measuring an unloaded tap changer, wait for the discharge indicator alarm sound to stop before switching gears.
⑤ Power outage handling: During the testing process, if there is a sudden power outage of external AC220V, the instrument will automatically discharge. At this time, it is not allowed to immediately remove the test line, and it is necessary to wait for 5 minutes before removing the line.
5. Precautions
① No load tap changer testing: It is not allowed to switch the no-load tap changer during the testing process or before the power is fully discharged.
② Sensitivity test object: For sensitivity test objects, it is not allowed to remove the test line before discharging the electricity to avoid electric shock.
③ Data storage: The original data is saved using an Access database for future query and analysis.
In summary, the transformer comprehensive test bench is an important equipment in the field of power transformer detection, with comprehensive functions, easy operation, high precision, and high efficiency. During use, it is necessary to strictly follow safety measures and precautions to ensure the accuracy of test results and the safety of the testing process.
The ZC-200 transformer comprehensive test system is mainly used for testing the no-load characteristics, load characteristics, winding resistance, transformation ratio group, power frequency withstand voltage, induction withstand voltage, insulation resistance of power transformers and distribution transformers. The system adopts a modular design, where each testing unit can work independently and can be automatically tested under computer control. The test data of each project can be directly obtained by the computer and can form test reports. This system avoids random errors caused by manual observation and recording of data, and greatly improves experimental efficiency.
