A device and method for installing and pre-adjusting molds of transformer coils based on APG

Abstract

The invention provides an APG-based transformer coil mold mounting pre-adjusting device and a method thereof. The pre-adjusting device comprises a limiting device and an adjusting device. The limitingdevice comprises a base, two vertical plates and a back plate. The adjusting device comprises a first mounting plate, a second mounting plate, a first fixing block, a second fixing block and a winding fixing block. The connecting wires of the first transformer coil, the second transformer coil and the first transformer coil can be fixed on the two mounting plates respectively through the three fixing blocks. The two vertical plates are provided with grooves, wherein a first limit groove, a second limit groove and a third limit groove are formed between the two vertical plates, the first limitgroove and the first mounting plate are matched, the second limit groove and the second mounting plate are matched, and the third limit groove and the winding fixing block are matched. As that devicedoes not need to adjust the coil unde the high temperature, the mold can be quickly closed to reduce the temperature drop, and the device has the advantages of high processing safety, high product quality and high production efficiency.

Description

Technical field [0001] The invention relates to the field of transformer manufacturing, in particular to an APG-based transformer coil assembly pre-adjustment device and method. Background technique [0002] Transformer, also known as instrument transformer, is the collective term for current transformer and voltage transformer. It can turn high voltage into low voltage and large current into small current for measurement or protection system. Its function is mainly to convert high voltage or large current into standard low voltage or standard small current in proportion to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. At the same time, transformers can also be used to isolate high-voltage systems to ensure the safety of people and equipment. [0003] In the transformer manufacturing process, in order to improve production efficiency, a mold with two molding cavities is used, and two transformers ca...

Problems solved by technology

However, in the specific production process, it is necessary to adjust the positions of the two coils at high temperatures, which is difficult to adjust, and there is a risk of scalding the staff; at the same time, it takes a long time to adjust the positions of the two coils, and the temperature of the transformer coil will drop quickly , will reduce the quality of transformer products after mold closing
