Abstract

The invention relates to a semi-automatic detection method for a withstand voltage test of a high-voltage transformer. The method comprises the following steps: (1) the high-voltage transformer uses apallet as a carrier, an operator puts the transformer and the pallet onto a conveyor line by a forklift or other lifting tools; (2) a positioning module performs a precise positioning after reachingthe specified position, a positioning system is composed of a chamfered pin shaft and has a ground connection function, and a secondary automatic wiring module and a primary wiring module perform wiring after precise positioning, wherein a PLC control system issues commands to automatically perform the above operations; (3) after the wiring, a verification system performs verification analysis oneach detection item; (4) an upper computer control system determines whether the verification analysis result is qualified or not, and the results of some verification items need manual determination.The semi-automatic detection method for the withstand voltage test of the high voltage transformer improves the verification efficiency and improves the safety of high-pressure item detection.

Description

technical field [0001] The invention belongs to the technical field of electric energy measurement, in particular to a semi-automatic detection method for a high-voltage transformer withstand voltage test. Background technique [0002] With the investment in automatic measurement and verification production equipment, large-scale smart energy meters and automatic verification of low-voltage transformers have been widely used.
