Explosion-proof type high-safety transformer iron core

Technical Field

The utility model relates to the field of iron cores, in particular to an explosion-proof and explosion-proof high-safety transformer iron core.

Background

The core is the main magnetic circuit part in the transformer. Usually made by stacking hot-rolled or cold-rolled silicon steel sheets containing silicon in a high content and coated with an insulating varnish on their surface. The iron core and the coil wound on the iron core form a complete electromagnetic induction system. The amount of power transmitted by the power transformer depends on the material and cross-sectional area of the core.

But the EI iron core passes the EI iron core through the screw rod at present and fixes, but when needs were changed the EI iron core, need take out EI iron core is whole to be changed, change very trouble and inefficiency like this.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

Referring to fig. 1-3, an explosion-proof and explosion-proof high-safety transformer core comprises an E-type lamination 1 and an I-type lamination 2, wherein gaskets 3 are arranged on two sides of the E-type lamination 1 and the I-type lamination 2, a rotating groove 4 is formed in each gasket 3, a rotating first screw 5 is arranged in each rotating groove 4, and the two gaskets 3 are fixed through the first screw 5.

As shown in fig. 3, two sides of the E-shaped lamination 1 are provided with limiting grooves 7 corresponding to the rotating grooves 4, and the first screw 5 rotates in the rotating groove 4, and can be clamped in the limiting grooves 7 when turning to the E-shaped lamination 1, so as to limit the E-shaped lamination 1.

As shown in fig. 3, two sides of the I-shaped lamination 2 are provided with limiting grooves 7 corresponding to the rotating grooves 4, and the first screw 5 rotates in the rotating groove 4, and can be clamped in the limiting grooves 7 when turning to the I-shaped lamination 2, so as to limit the I-shaped lamination 2.

As shown in fig. 2 and 3, a rotating rod 6 is fixed at the connecting end of the first screw 5, two ends of the rotating rod 6 rotate on the side wall of the rotating groove 4, the first screw 5 can rotate in the rotating groove 4 through the rotating rod 6, and when the E-shaped laminations 1 and the I-shaped laminations 2 need to be extracted, the first screw 5 is rotated towards two sides, so that the middle E-shaped laminations 1 and the I-shaped laminations 2 can be extracted.

As shown in fig. 2, a second screw 8 is disposed at an end of the gasket 3 away from the first screw 5, the second screw 8 is disposed perpendicular to the first screw 5, and the first screw 5 and the second screw 8 are disposed perpendicular to each other to form a frame for fixing the E-shaped laminations 1 and the I-shaped laminations 2 inside.
