Abstract

The invention discloses a vehicle-mounted transformer comprehensive test system. The system is characterized by comprising an industrial personal computer (IPC), a communication module, a hub conversion plate, a short-circuit impedance short connector, a load switch adjuster, and a comprehensive test device, wherein the IPC carries out data communication with each test device of the comprehensive test device through the communication module; each test device of the comprehensive test device is connected with the hub conversion plate through an internal connection wire; the hub conversion plate is connected with a tested transformer through a test wire; a medium-voltage short-circuit impedance short connector and a low-voltage short-circuit impedance short connector are respectively connected with the medium-voltage side and the low-voltage side of the tested transformer through the test wire; the load switch adjuster is connected with a load switch adjusting device of the tested transformer through the test wire. The comprehensive test system provided by the invention can complete all of the test items by a single connection, thereby avoiding frequent replacement of instruments and connection wires.

Description

technical field [0001] The invention belongs to the technical field of electric power comprehensive measurement, in particular to a vehicle-mounted comprehensive testing system and method for transformers, and belongs to the technical field of transformer testing. Background technique [0002] In the comprehensive power measurement technology, the traditional power comprehensive test vehicle needs to use six different instruments to measure the transformer's insulation resistance, short-circuit resistance, DC resistance, on-load, transformation ratio, and dielectric loss. Separate measurement, the measurement wiring amount is large and complicated, and it needs to be connected and measured separately for multiple times. Moreover, so many instruments need to be installed on a comprehensive electric test vehicle, which not only occupies a large amount of limited space of the comprehensive electric test vehicle, but also reduces the test functions of the comprehensive electric ...
