A kind of transformer that has isolation mounting
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:
Embodiment 1: a certain miniature transformer S9-1000/10, its capacity is 1000KVA, voltage is 10KV, its structure as shown in Figure 1, comprise transformer core 1, core clamping 3, fuel tank 4, winding and insulate 5, sleeve pipe 6, as shown in Figure 2: be wound with winding on every side and 5 the transformer core 1 of insulating places on the base of fuel tank 4, core clamping 3 places winding and the transformer core of 5 ends of insulating 1 iron yoke place, between transformer core 1 and the core clamping 3 around it thick rubber blanket 2 of 4mm is installed.Rubber blanket 2 is oil resistant, high temperature resistant, vibration isolation rubber.Because isolation mounting is installed, reduced the noise of transformer core from root, make transformer noise be reduced to 45 decibels from 47 decibels.
Embodiment 2: a certain high-power transformer SZ9-31500/110, be three-phase transformer, its capacity is 31500KVA, voltage is 110KV, its structure as shown in Figure 1, comprise transformer core 1, core clamping 3, fuel tank 4, winding and insulate 5, sleeve pipe 6, as shown in Figure 2: be wound with winding on every side and 5 the transformer core 1 of insulating places on the base of fuel tank 4, core clamping 3 places winding and the transformer core of 5 ends of insulating 1 iron yoke place, between transformer core 1 and the core clamping 3 around it thick rubber blanket 2 of 4.5mm is installed.Rubber blanket 2 is oil resistant, high temperature resistant, vibration isolation rubber.Because isolation mounting is installed, reduced the noise of transformer core from root, make transformer noise be reduced to 63 decibels from 65 decibels.
Embodiment 3: a certain high-power transformer SFP9-370000/500, be three-phase, air-cooled, strong oily circulating transformer, its capacity is 370000KVA, voltage is 500KV, its structure as shown in Figure 1, comprise transformer core 1, core clamping 3, fuel tank 4, winding and insulate 5, sleeve pipe 6, as shown in Figure 2: be wound with winding on every side and 5 the transformer core 1 of insulating places on the base of fuel tank 4, core clamping 3 places winding and the transformer core of 5 ends of insulating 1 iron yoke place, between transformer core 1 and the core clamping 3 around it thick rubber blanket 2 of 5mm is installed.Rubber blanket 2 is oil resistant, high temperature resistant, vibration isolation rubber.Because isolation mounting is installed, reduced the noise of transformer core from root, make transformer noise be reduced to 70 decibels from 72 decibels.
