Description

Transformer coil spacer structure

The present invention relates to a transformer coil spacer structure that avoids coil dumping and effectively increases the mechanical strength of the transformer coil spacer structure in the longitudinal and transverse directions.

In terms of power equipment, the structure of the transformer is becoming more and more mature, so the overall structure must have good wet and dust resistance, high insulation and easy maintenance.

As shown in FIG. 1 , a general transformer has a coil body 10 therein, and the coil body 10 is mainly composed of a core 11 , a coil 12 , a spacer 13 , a T-type oil passage spacer 14 and a square oil passage spacer 15 ; Each of the coils 12 is wound around the core 11 , and each of the coils 12 is provided with the spacers 13 , and the spaces between the turns of the coils 12 are mainly spaced apart to increase the electrostatic capacitance between the turns of the coils 12 ; Each of the spacers 13 is designed with a double hook type opening at one end and an open type opening at the other end, the T-shaped oil passage spacer 14 is installed at the double hook type opening, and the square oil passage spacer is installed at the open type opening. 15; However, the square oil passage strip 15 is liable to fall off during assembly, and when the system is short-circuited, the oil passage spacer is displaced, and the coil 12 cannot be prevented from falling over.

Based on the above reasons, there is still room for improvement in the prior art. In view of this, the creator has actively studied and developed the experience of related product research and development for many years, and through continuous experimentation and improvement, finally developed this creation.

The main purpose of this creation is to provide a transformer coil spacer structure, a double hook type opening of the spacer, and a T-type oil passage spacer can be engaged, and a T-shaped oil passage spacer is installed at the two ends of the spacer. At the same time, the spacers and coils can be firmly fixed to prevent the coil from falling over when the system is short-circuited.

The secondary purpose of this creation is to provide a transformer coil spacer structure in which the spacers are arranged in the longitudinal direction. At the same time, T-shaped oil passage spacers are installed at both ends of the spacer, which can increase the longitudinal and lateral directions of the transformer coil spacer structure. Mechanical strength.

In order to achieve the above purpose, the present invention provides a transformer coil spacer structure which is installed inside a transformer and includes a core, a coil, a spacer and a T-type oil spacer. Each of the coils is wound around the core; each of the coils is provided with each of the spacers, and the main function is to make a space between each turn of the coils, increase the electrostatic capacitance between the coil turns, and fix the The T-shaped oil passage spacers inside and outside the coil enable oil to enter the inside of each coil to improve the cooling capacity; the two ends of the spacer are double hook type openings for mounting the T-shaped oil passage spacers.

In order to further understand the features and technical contents of the present invention, please refer to the following detailed description and drawings of the present invention. However, the drawings are for reference and description only, and are not intended to limit the creation.

Please refer to FIG. 2 and FIG. 3 , FIG. 2 is a schematic cross-sectional view of a transformer coil spacer structure device in a transformer, and FIG. 3 is an exploded perspective view of a transformer coil spacer structure; The sheet structure 20 is mounted inside the transformer 30 and includes a core 21, a coil 22, a spacer 23 and a T-type oil passage spacer 24. Each of the coils 22 is wound around the core 21; a plurality of spacers 23 are disposed on each of the coils 22, and are centered on the center of the core 21, and are distributed in a radial pattern on each of the coils 22, the spacers 23 Both ends are double hook type openings for mounting the T type oil passage spacers 24.

4A and FIG. 4B, FIG. 4A is a perspective view of the structure of the transformer coil spacer, and FIG. 4B is a partial enlarged view of FIG. 4A; the spacer 23 is disposed on each of the coils 22, and the main function is to make each Each space in the coil 22 is spaced apart to increase the electrostatic capacitance between the coils 22, and the T-type oil passage spacers 24 inside and outside the coil 22 are fixed, so that oil can enter the coil 22 and lift. Cooling capacity.

Further, referring to FIG. 2, when the transformer coil spacer structure 20 is assembled, the transformer coil spacer structure 20 must be lifted and placed inside the transformer 30.

In summary, the double hook type opening at both ends of the spacer 23 can engage the T-shaped oil passage spacer 24, so that the T-shaped oil passage spacer 24 can be prevented from falling off when assembled; meanwhile, when the system is short-circuited The coil 22 can also be supported to prevent the coil 22 from being tilted; in addition, the spacers 23 are vertically aligned, and the T-shaped oil passage spacers 24 are installed at both ends of the spacer 23, so that the transformer can be added. The mechanical strength of the longitudinal and transverse directions of the coil spacer structure 20.
