[0003] The object of the present invention is to provide a structure and method for connecting the device body and the fuel tank cover for vibration reduction and noise reduction. By installing a connecting piece between the body clip web of the device body and the fuel tank cover, the The large vibration transmission space between the oil tank cover and the transformer oil forms a buffer support, thereby playing the role of vibration and noise reduction of the oil tank cover, and further providing effective help for transformer / reactor test or vibration reduction and noise reduction during operation. Solve the problem of vibration and noise in the suspension state of the box cover

The invention relates to a transformer body and oil tank cover connecting structure and method for vibration and noise reduction, and belongs to the technical field of transformer / electric reactor manufacturing. According to the technical scheme, when an oil tank cover (14) is installed, lower legs of tank cover channel steel (1) are fixedly connected with vibration reduction rubber pads (3) through rubber pad positioning bolts (2), and a transformer body and oil tank cover connecting structure is supported between the oil tank cover (14) and a transformer body clamping piece web (12); the oiltank cover (14) and the oil tank wall (13) are installed together, and at the moment, the whole transformer body and the oil tank cover are connected into a whole through the transformer body and oiltank cover connecting structure to jointly reduce vibration and noise. The structure and the method have the beneficial effects that the number of fixed connecting points of the transformer body is increased, the vibration amplitude of the transformer body is reduced, and therefore the vibration and noise reduction effects are achieved. Materials used by the structure are consistent with transformer / electric reactor application materials, potential safety hazards are avoided, and independent maintenance is not needed.
Description
technical field [0001] The invention relates to a structure and method for connecting a device body and a fuel tank cover for vibration reduction and noise reduction, is a partial connection structure of a transformer or a reactor, and belongs to the technical field of transformer / reactor manufacturing. Background technique [0002] High-voltage shunt reactors or ultra-high voltage and ultra-high voltage power transformers are large-scale power equipment and an important part of power transmission and transformation systems. Their noise is an important factor affecting the noise of substations. Especially during the test or operation of the transformer / reactor, the vibration and noise generated will spread to the ground and the surrounding space, causing greater vibration and noise pollution. As noise pollution has been widely concerned by the public and environmental protection departments, reducing its noise and vibration levels and achieving low noise for power transmissi...
