Overview

SUTE-8350 Transformer DC Resistance Tester The DC resistance of transformers is a necessary test item for semi-finished and finished product factory testing, installation, handover testing, and preventive testing by power departments in transformer manufacturing. It can effectively detect manufacturing defects such as loose materials, welding, connection parts, missing strands, and broken wires in transformer coils, as well as hidden dangers after operation. In order to meet the needs of rapid measurement of transformer DC resistance, our company has developed a transformer DC resistance tester using our own technological advantages.

SUTE-8350Transformer DC resistance tester

1 Overview

For the power system, transformers are the core equipment in the system, so the long-term and reliable operation of transformers is related to the stability and reliability of the entire system.

The DC resistance of transformers is a necessary test item for semi-finished and finished products in transformer manufacturing, factory testing, installation, handover testing, and preventive testing by the power department. It can effectively detect manufacturing defects such as material selection, welding, loose connection parts, missing strands, and broken wires of transformer coils, as well as hidden dangers after operation.In order to meet the needs of rapid measurement of DC resistance in transformers, our company has developed using our own technological advantagesA transformer DC resistance tester. This instrument is a setMagnetic assisted testing, three-phase testing（and Y,andDemagnetization functionThe new generation of rapid testing equipment integrated into one isIdeal equipment for measuring the DC resistance of large power transformers.The screen adopts a true color large screen high-resolution LCD display, with touch control and shuttle knob operation, making it convenient for on-site use. It has a Chinese menu prompt function, easy and intuitive operation, and can complete all direct resistance test items in one wiring. The testing speed is fast, the accuracy is high, and the range is wide.

2Main functions and features

2.1 ForYn type, Y type, and △ type windings can all be tested using three-phase measurement method, and the three-phase unbalance rate can be calculated.

2.2 Test the output current of the power supply50A， Test range 0~25K Ω, meeting the testing requirements of the vast majority of transformers; And it integrates magnetic assistance and demagnetization functions to meet various on-site testing needs.

2.3 The testing process can automatically calculate5S、15S、30The rate of change in resistance value within S can assist testers in determining the stability of test data and prevent misreading of data.

2The instrument has 380Multiple protection functions such as V misconnection protection, back electromotive force protection, wire breakage protection, and power-off protection, as well as an alarm function for ungrounded grounding wire.

2.5 The instrument is equipped with a thermal printer, which stores data locally200Supports massive storage on USB drives.

2.6 industrial-grade7The inch true color large screen display features a fresh and simple display style design, with full touch and one click shuttle operation, creating a comfortable and convenient human-machine interaction experience for you.

4Precautions

Test the no-load voltage regulating winding, and it is not allowed to switch the no-load tap changer during the testing process or before discharging the power.

It is not allowed to remove the test line and cut off the power switch during testing or discharging.

During the testing of the transformer, the winding on the unmeasured side of the transformer must be open circuited.
