Abstract

The present invention relates to a high-voltage current transformer verification wiring device. The high-voltage current transformer verification wiring device includes a rack and a flatbed cart; the flatbed cart is provided with a plurality of grooves; the bottom of the rack is provided with a positioning channel; two sides of the positioning channel are provided with rubber chains driven by a motor; the top of the rack is slidably provided with a lifting pressing plate driven by a lifting driving mechanism; the bottom surface of the lifting pressing plate is provided with a plurality of metal pressing blocks at intervals; the metal pressing blocks are corresponding to bosses at the top ends of transformers; after the lifting pressing plate descends, the metal pressing blocks are electrically and correspondingly connected with the bosses; conductors are arranged between the metal pressing blocks, so that the transformers can be connected in series with two ends of a power source for detection; and two side portions of the rack are provided with a plurality of retractable elastic pushing pins. With the wiring device of the invention adopted, primary-side wiring and secondary-side wiring can be simultaneously performed on a plurality of transformers in a semi-automatic manner, and therefore, wiring efficiency can be improved, and wiring difficulty can be reduced. The device has the advantages of simple structure and convenient control, and can greatly improve verification efficiency and reduce labor intensity.

Description

technical field [0001] The invention relates to the verification operation field of high-voltage current transformers, in particular to a verification wiring device for high-voltage current transformers. Background technique [0002] High-voltage current transformers are used to convert large currents into standard small currents in proportion to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. Transformers can also be used to separate high-voltage systems to ensure personal and equipment safety. . The stability and accuracy level of high-voltage current transformers directly affect the measurement accuracy and accuracy of measuring instruments. Therefore, high-voltage current transformers need to be strictly calibrated before use. At present, there are many automatic testing equipment for transformers that can calibrate a single high-voltage current transformer. [0003] For a high-voltage curr...
