Abstract
The utility model relates to a transformer with a vibration isolator, which belongs to the technical field of transformers. The structure of the transformer comprises a transformer iron core, an iron core clamping piece, an oil tank, windings, an insulator and a pipe casing, wherein the transformer iron core which is surrounded by winding the windings and the insulator is arranged on a base of the oil tank, the iron core clamping piece is arranged on the end parts of the windings on both sides of the transformer iron core and the insulator, and the vibration isolator is arranged between an iron yoke of the transformer iron core and the iron core clamping piece and is a rubber pad. The rubber pad can resist oil and high temperature and can isolate vibrations. The utility model has the advantages that the vibration isolator is arranged between the transformer iron core and the iron core clamping piece; noise is reduced thoroughly; the utility model has low cost and can act rapidly; the noise of the transformer can be reduced by 2 decibels.
Description
Technical field
The utility model belongs to the transformer technology field, especially belongs to a kind of transformer that has isolation mounting.
Background technology
Noise pollution, water pollutes, and air pollution is listed in three big public hazards in the world, and transformer noise is very big to the mankind's harm, and the user presses for the reduction noise of transformer.The vibration of transformer core silicon steel sheet is the root that produces noise, the isolation mounting of existing transformer is between iron core and fuel tank rubber blanket to be set, in the transformer course of work, can not well eliminate the noise of generation, bring and have a strong impact on for human being's production, life.
The utility model content
In order to solve the problem of above-mentioned existence, the utility model provides a kind of transformer that has isolation mounting.It is to reduce noise of transformer by increase isolation mounting around transformer core, makes its propagation that reduces iron coring vibration, reduces transformer noise.
Structure of the present utility model comprises transformer core, core clamping, fuel tank, winding and insulation, sleeve pipe, the transformer core that is wound with winding and insulation on every side places on the base of fuel tank, core clamping places the transformer core iron yoke place of winding and insulation end, between transformer core iron yoke and core clamping isolation mounting is installed, its isolation mounting is the thick rubber blanket of 4mm～5mm.This rubber blanket has the effect of oil resistant, high temperature resistant, vibration isolation.
The utility model has the advantages that between transformer core and folder isolation mounting is installed, reduce noise from root, cost is low, and instant effect can reduce by 2 decibels of transformer noises.
Description of drawings
Fig. 1 is an overall structure cross-sectional schematic of the present utility model,
1 transformer core among the figure, 2 rubber blankets, 3 core clampings, 4 fuel tanks, 5 windings and insulation, 6 sleeve pipes.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further:
