Mobile installation for the diagnosis of power distribution transformers

摘要

The utility model refers to diagnostic tools for power transformers and is intended for use in places of their operation, as well as when commissioning new power transformers in order to control the compliance of the actual values of no-load losses and short-circuit losses with the required energy efficiency class. Technical result: increased functionality. Essence: an autonomous generator 2 of three-phase voltage of industrial frequency, a block of measuring current transformers 3, a measuring unit 4, a regulator 5 of a three-phase voltage are mounted on the chassis 1 of the vehicle. The regulator 5 is configured to generate an output voltage that exceeds its input voltage by at least 10%. Generator 2 is configured to generate currents exceeding at least three times the rated value of the no-load current of the diagnosed power transformer. 1 Il.
