Automatic Transformer Test Bench

1. This technical proposal specifies the design, manufacturing, inspection, testing, technical data, acceptance, delivery and transportation, on-site debugging, after-sales service and other tasks of the transformer comprehensive test bench.

2. The products provided by the supplier have stable performance and reliable testing data, which are widely used in transformer and power reactor production and testing enterprises and are well received by users.

The following tests are following the standard IEC60076-1 ~5《power transformer》 and IEC60726《dry-type electric transformer》. The test items are shown in the following table:

Design specification for a comprehensive test system in the transformer laboratory:

1. System operation is simple, safe, and reliable

The whole test system takes into account the safety of test personnel and the reliability of equipment operation

Various overvoltage and current protection functions are complete.

The space layout is reasonable and the wiring is clear and neat.

2. system efficiency

Make full use of microcomputer data processing technology, the measurement results are directly entered into the microcomputer for calculation. Save the trouble of manually substituting into the formula calculation. The external wiring is arranged in a unified manner, manual wiring is avoided as far as possible, and automatic switching is completed only with the control button on the test bench when the wire is changed.

3. System humanized operation

Make full use of the mechanical and electrical interlock functions, and skillfully combine them with the computer software program, effectively preventing the occurrence of misoperation, that is, if you do not operate in accordance with the safety procedure, the system will refuse to start, so as to effectively protect the safety of people and equipment

4. Reliable system operation

The system has two operation modes: manual and automatic. When the automatic operation mode is abnormal, the manual operation mode will be used, which will not affect the normal test task

5. System measurement accuracy is high

The measuring instruments and instruments of this system are higher than the national standard requirements.

Transformer characteristic test：

A．manual function

■ Use the buttons on the front panel to control the test program.

■ Record the test data manually and save it in the database.

■ The test process can be completed by PC software and loss meter data communication.

■ Test items can be selected by button, and only one test task can be run at a time.

■ All test functions and test procedures are selected and controlled by buttons on the front panel of the test bench.

automatic function

■ The test process can be controlled by the PC software on the PC, using the mouse and keyboard.

■ Test data can be automatically recorded and saved in the database.

■ The keys on the front panel can be invalid during automatic operation.

■ Test items can be selected through the button in the dialog box, and only one test task can be run at a time.

■ No load, load test, automatically record the ambient temperature.

■ In the temperature rise test, the automatic control function of constant power and constant current is supported, and the temperature test data is automatically recorded every 15 seconds (or an optional interval).

■ Test results such as insulation resistance and oil pressure resistance can be manually entered into the file to improve the test report.

■ Calibration of all test results according to the requirements of GB1094, IEC 60076 or ANSI C57 sequence latest standards.

■ After the test is completed, the database archive is automatically completed and the test report can be printed immediately.

■ Temperature rise test, can accurately calculate the test data automatically.

■ Can automatically perform waveform correction, rated voltage correction, frequency correction (50Hz, 60Hz) for no-load test data.

■ Automatic temperature correction (75 ° C, 100 ° C, 120 ° C, 145 ° C), rated current correction, frequency correction for load test data.

■ In no-load test, the high-voltage side voltage can be monitored, recorded and spectrum analysis.

■ During the load test, the low-voltage current can be monitored, recorded and analyzed.

 The performance meets the following requirements:

■The direct loop and indirect loop can be switched automatically.

■ The high-voltage current and voltage transformer adopt the principle of secondary switching.

■CT\PT automatic range switching

■transformer integrated test bench for the entire circuit for comprehensive control and measurement monitoring.

■The measured data are processed automatically by microcomputer and can be stored/printed as required.

■Adopt microcomputer automatic control measuring system test bench and manual operation electric control voltage regulation digital display two complementary systems.

■Zero protection, over current protection, over-voltage protection.

■ High voltage leakage current display and protection, 1:1 transformer safety grounding.

■The test transformer adopts the new oil-immersed test transformer with stronger insulation and greatly reduced volume capacity. Test station auxiliary facilities

■Safety alarm system.

■ System error alarm system.

■stainless steel isolation fence.

■Audible and visual danger warning system
