Field of the Invention The present invention relates to a stationary induction electric device, and more particularly to a stationary induction device suitable for a device in which a sound insulation plate is arranged on an outer surface of a tank, such as a transformer or a reactor, in order to reduce noise generated from the electric device body. Related to electrical appliances.

Description of the Related Art In recent years, as residential areas have been constructed close to substations and the like due to the expansion of urban areas, there has been a demand for lower noise levels for stationary induction devices such as transformers and reactors. It's getting stronger.

り、これを防ぐために種々の防止策がとられている。[0003] The noise of a stationary induction electric machine is divided into noise generated by an iron core of the electric appliance body and noise generated by auxiliary equipment such as a blower and an oil pump of a cooler. Of these, electromagnetic vibration due to magnetostriction of the iron core is included. Is transmitted to the tank through an insulating medium such as insulating oil or gas, and is radiated to the outside as noise due to the vibration of the tank. The noise energy due to the electromagnetic vibration accounts for a large proportion of the noise of the entire stationary induction device. And various preventive measures have been taken to prevent this.

遮音板を取付ける方式がある。[0004] For example, as a method of insulating or absorbing a static induction device by means of a soundproof building made of concrete or iron plate, or as a measure for easily reducing the noise radiated from the tank, a reinforcing stay disposed on the outer surface of the tank is used. There is a method of installing a sound insulating plate between them.

タンク1より放射される騒音を低減している。In the stationary induction device having the above-described configuration, when the iron core 6 is excited, electromagnetic vibration is generated in the iron core 6. This electromagnetic vibration is transmitted to the tank 1 with little attenuation by the insulating medium 8 having characteristics close to incompressibility, and the tank 1 generates noise. In order to reduce this noise, a soundproof building 9 made of concrete or iron plate is constructed so as to surround the tank 1, and the noise radiated from the tank 1 is sound-insulated or absorbed. 13 shows an upper reinforcement stay 3 and a lower reinforcement stay 4 arranged on the outer surface of the tank 1 in order to reduce noise radiated from the tank 1.
This method is to install a sound insulating plate between the upper and lower reinforcing stays 3 and 4 fixed to the side plate 2 to reinforce the strength of the side plate 2 of the tank 1. A sound insulating plate 11 made of a damping steel plate is attached via a thin steel plate 10 as an elastic body, and the noise radiated from the tank 1 is reduced by the elastic effect of the thin steel plate 10 as a spring element and the damping action of the damping steel plate. are doing.

There are various disadvantages, such as an increase in installation area, an increase in manufacturing cost, and a prolonged construction period. Further, the method of mounting the sound insulating plate 11 between the upper and lower reinforcing stays 3 and 4 arranged on the outer surface of the tank 1 cannot secure a sufficient area for mounting the sound insulating plate 11, so that noise cannot be sufficiently reduced. There is.

Needless to say, by providing the second sound insulating plate having a high sound insulating effect independently of the foundation, problems such as an increase in the installation area of the stationary induction device, an increase in the manufacturing cost, and a prolonged construction period are not caused. A large amount of noise reduction can be obtained. Also, the second sound insulation plate is
The structure of the tank and the lower reinforcement stays are used as a support part and extend further outward, so if transported as it is, it will greatly affect the transport restrictions of transformers and reactor tanks. Will give. Therefore, in the present invention, at the time of the performance confirmation test, the support portion and the main body, so that the original performance can be exhibited by removably fastening the fastening brackets provided by protruding from members such as bolts, In the field, since the support part and the main body side can be welded as a permanent state,
After the performance confirmation test is completed, the main body and the sound insulating plate can be transported separately, and the transportation restrictions can be met.
