Description

Technical Field

[0001] The invention belongs to the technical field of current transformers, and in particular relates to an insulation wrapping and shaping jig for current transformers. Background Art

[0002] As we all know, the mutual inductor is also called instrument transformer, which is a general term for current transformer and voltage transformer. It can convert high voltage into low voltage and high current into low current, and is used for measurement or protection system. Its main function is to convert high voltage or high current into standard low voltage (100V) or standard low current (5A or 1A, both refer to rated value) in proportion, so as to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. At the same time, the mutual inductor can also be used to isolate the high voltage system to ensure the safety of people and equipment.

[0003] At present, when the transformer is insulated and wrapped, if the inner diameter of the wire package is small and the height is high, the general roll-shaped adhesive tape is not easy to operate, and a long shuttle is needed to wrap the wire package. The shuttle tool currently used requires manual pouring of the roll-shaped adhesive tape on the long strip epoxy board, which is time-consuming and laborious. Summary of the invention

[0004] The purpose of the present invention is to provide a current transformer insulation wrapping shaping jig in order to solve the above-mentioned problem. The jig can be used for wrapping and shaping during the insulation wrapping stage and fixed at key positions of the wire wrap frame. During the insulation wrapping stage, the positioning columns can be plugged in and out at any time according to needs. After the wrapping is completed, the jig is solidified to ensure the insulation distance and the symmetry of the overall wire wrap.
