Abstract
The utility model relates to an insulation of iron yoke used for transformer. The insulation of iron yoke has functions of pressing and fixing coil and iron core as well as fixing partition plate at the same time. Furthermore, insulation between end of coil and the iron core is strengthened and vibration and noise are reduced by the insulation of the iron yoke. The insulation of the iron yoke is an entirety that the first insulating plate and silica gel underlay, the secondary insulating plate and silica gel underlay are bound together with glue. The utility model has advantage that the coil is fixed in axial direction and the partition plate is directly set up on it, which not only simplifies operation of worker but also makes the fastness in axial direction between the coil and the iron core more reliable, furthermore the stress between the coil and the iron core becomes more average and performance of insulation is also promoted. The operation of drilling on the clamping piece is eliminated and efficiency of assembly is promoted. The silica gel underlay not only functions as insulation, but also reduces vibration and noise.
Description
Technical field
The utility model relates to a kind of transformer core insulation, this core insulation can play the effect that press-fits fixed coil and iron core and immobile phase space bar simultaneously, strengthens end winding and insulation unshakable in one's determination, reduces vibrations and noise.Belong to the transformer technology field.
Background technology
At present general dry-type transformer does not have this structure. originally the iron core of transformer and coil axes between fixing main the employing on the folder of clamping iron core punch, then by pressing nail pressure die briquetting that coil is fixed, thereby guarantee the tram between coil and the iron core, between iron yoke and coil, there be not such fixing, phase partition between the coil fixedly is to adopt fixation clamp to be fixed, fixation clamp is fixed on high pressure folder and low pressure folder both sides earlier, and then between phase partition is fixed on.
Summary of the invention
The purpose of this utility model is to propose a kind of transformer core insulation, and this core insulation can play the effect that press-fits fixed coil and iron core and immobile phase space bar simultaneously, strengthens end winding and insulation unshakable in one's determination, reduces vibrations and noise.Technical solution of the present utility model: its structure be core insulation by between first insulation board, first silicagel pad, second silicagel pad, second collets, first collets with glue firm be bonded into an integral body.
Advantage of the present utility model: to having played fixation, phase partition can be directly installed on it, has not only simplified workman's operating procedure to coil axes, and make coil and stalk between fixing more firm.Make between coil and the iron core stressed more evenly and improved insulation property, phase partition is directly fixed thereon, reduced the operation of on folder, changeing the hole, thereby improved the efficient of assembling, top silicagel pad has also played damping when playing insulating effect, reduce the effect of noise
