ON-SITE TEST METHOD AND SYSTEM FOR NO-LOAD/LOAD LOSS OF VEHICLE-MOUNTED POWER TRANSFORMER

摘要

The present invention relates to the field of electrical technology, and more particularly, to an on-site test method and system for no-load/load loss of a vehicle-mounted power transformer. The on-site test method uses an on-site test system for no-load/load loss of a vehicle-mounted power transformer. The on-site test system comprises: a test system and a side-open carriage. The test system is located in the side-open carriage. The test system comprises: a test connection end for connecting a transformer under test, a power supply device for providing a test voltage to the transformer under test, a measurement instrument for obtaining measurement data of the transformer under test, and a measurement control device for controlling the measurement instrument. The power supply device, the measurement instrument, and the measurement control device are all located on a test circuit where a test connection end is located. The input end of the power supply device is connected to a power supply at a test site. By means of the present invention, on-site test for no-load and load of a large power transformer can be implemented.
