In detail. Among them, a joint reinforcing portion is provided as a measure for preventing the mouth of the joint between the tank and the cover from being prevented. In recent years, a large number of electric devices, such as those having a constant capacity inside the tank, such as gas-insulated transformers and gas-insulated transformers, have been produced, and the technology in this field has become especially important. . 3 and 4 show a container of a conventional electric device, in which 1 is a tank for housing components of the electric device, and 2 is a cover overlaid on the tank 1 in order to isolate the components from the outside air. 1a,
Reference numeral 2a is a flange provided for joining the tank 1 and the cover 2 to each other. Reference numeral 4 is a tank reinforcing portion that prevents deformation of the tank 1, and 5 is a cover reinforcing portion. Reference numeral 6 is a joint reinforcing portion for preventing the flanges 1a and 2a from fluttering.

ある。Next, the operation will be described. Insulating oil mainly composed of mineral oil and gas 7 such as nitrogen and SF 6 gas are enclosed as a medium for the insulation cooling in the tank 1, and heat generated from the iron core and winding of the device due to the operation of the electric device and the device The pressure in the tank 1 increases or decreases according to the change in ambient temperature at which the tank is installed. Moreover, due to an internal accident (so-called electrical accident) of the electric device, the internal insulator is rapidly pyrolyzed, a large amount of decomposed gas is generated, and as a result, the internal pressure of the tank 1 is rapidly increased. In order to prevent the tank 1 and the cover 2 from being deformed due to the increase in the pressure, the tank reinforcing portion 4 and the cover reinforcing portion 5 are provided at appropriate intervals. However, a force corresponding to the surface pressure that the reinforcing portions 4 and 5 bear is concentrated at the end of the reinforcing portion, and the flange 1
He will speak to a and 2a. The function of the joint reinforcing portion 6 is to relieve the stress generated in the flanges 1a and 2a by interlocking and distributing the concentration force of the reinforcing end portion with the tank reinforcing portion 4 and the cover reinforcing portion 5. .

程、機器の外形寸法が増大するという問題点があった。In the conventional electric device, since the joint reinforcing portion 6 is constructed as described above, the joint reinforcing portion 6 must be provided outside the tank reinforcing portion 4, and There was a constraint that the joint reinforcing portion 6 had to be attached after the flanges 1a and 2a were completely welded. Further, the stronger the joint reinforcement section 6, the larger the external dimensions of the device.
