Description

A damping device for reducing noise of dry-type transformer

technical field

The utility model relates to a damping device for reducing the noise of a dry-type transformer, which belongs to the technical field of electric equipment transportation auxiliary devices.

Background technique

In addition, the particularity of the mobile substation is that the transformer is placed on a vehicle that moves frequently, and external factors such as road conditions may not be able to predict the damage to the transformer under the actual possible vibration. There are also high requirements for noise. However, the noise reduction measure of dry-type transformers is to use sound-absorbing cotton in the iron core, which has the risk of not being environmentally friendly or flammable.

Utility model content

The purpose of this utility model is: aiming at the defects of the prior art, to provide a shock absorbing device for reducing the noise of the dry-type transformer, which can not only reduce the noise, but also ensure the safety of the transformer during transportation, so as to overcome the disadvantages of the prior art. lack of.

Technical scheme of the utility model

A shock absorbing device for reducing the noise of a dry-type transformer, comprising a sound-insulating board laid on the bottom of a dry-type transformer and capable of sealing the upper iron core of the dry-type transformer, a shock-absorbing plate is arranged under the sound-insulating plate, and the sound-insulating plate is connected with the sound-insulating plate. Damping springs are arranged between the plates 1 .

In the aforementioned damping device for reducing the noise of dry-type transformers, a blind hole is set on the upper surface of the damping plate, and the damping spring is placed in the blind hole. By setting the blind hole and placing the damping spring in the blind hole, shock absorption The surface of the block is kept flat, and the sound insulation board is in good contact with the shock absorbing block. At the same time, the damping spring can effectively ensure the stability of its work in the blind hole, and the shock absorption of the transformer can be realized on the premise of ensuring the stable support of the transformer.

Due to the adoption of the above technical solution, compared with the prior art, the utility model has a simple structure, can effectively reduce the adverse effects of external vibrations on the dry-type transformer during transportation, and can effectively reduce the noise of the dry-type transformer and improve The comfort of on-site personnel solves the problem of anti-shock and vibration of the transformer during the transportation of the mobile substation, and improves the quality of the product.

detailed description

The utility model is used as a further detailed description below in conjunction with the accompanying drawings, but not as any limitation to the utility model.

Embodiment of the present utility model: a damping method for reducing the noise of a dry-type transformer. To reduce the noise, install a shock absorbing plate under the sound absorbing plate, and set a damping spring between the shock absorbing plate and the sound insulating plate to achieve shock absorption for the dry-type transformer. Set a blind hole on the upper surface of the shock absorbing plate, and place the damping spring in the blind hole. inside the hole.

A damping device for reducing the noise of a dry-type transformer constructed according to the above method, as shown in the accompanying drawings, includes a sound insulation board 1 laid on the bottom of the dry-type transformer and capable of sealing the upper iron core of the dry-type transformer. A shock absorbing plate 2 is arranged below the plate 1, a damping spring 3 is arranged between the shock absorbing plate 2 and the sound insulation plate 1, a blind hole 4 is arranged on the upper surface of the shock absorbing plate 2, and the damping spring 3 is placed in the blind hole 4.

In this embodiment, the device is composed of a damping block, a damping spring, and a sound insulation board. The sound insulation board is laid on the bottom of the dry-type transformer and the sound insulation board can seal the iron core of the dry-type transformer, thereby reducing the noise of the dry-type transformer. A blind hole is set on the surface, and the damping spring is placed in the blind hole. By setting the blind hole and placing the damping spring in the blind hole, the surface of the shock absorber is kept flat, and the sound insulation board is in good contact with the shock absorber. At the same time, the damping spring is placed in the blind hole. The interior can effectively guarantee the stability of its work, and can realize the shock absorption of the transformer under the premise of ensuring the stable support of the transformer, and the structure is simple, which can effectively reduce the adverse effects of external vibration on the dry-type transformer during transportation. At the same time, it can effectively reduce the noise of dry-type transformers, improve the comfort of on-site personnel, and solve the problem of shock resistance and vibration of transformers during transportation in mobile substations. Improve product quality.
