[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 structure and method for connecting a device body and a fuel tank cover for vibration reduction and noise reduction, and belongs to the technical field of transformer / reactor manufacturing. The technical solution is: when installing the fuel tank cover (14), the rubber pad positioning bolt (2) fixes the lower leg of the tank cover channel steel (1) with the vibration-damping rubber pad (3), and the connection structure between the body and the fuel tank cover Supported between the fuel tank cover (14) and the body clip web (12); the fuel tank cover (14) and the fuel tank wall (13) are installed together, at this time the entire body and the fuel tank cover pass through the body It is connected with the connection structure of the fuel tank cover to form a whole to reduce vibration and noise together. The beneficial effect of the invention is that: the number of fixed connection points of the device body is increased, the vibration amplitude of the device body is reduced, thereby achieving the effect of reducing vibration and noise. The material used in this structure is the same as that of the transformer / reactor, which does not bring safety hazards and does not require separate maintenance.
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...
