Description

An airtight container reinforcing member for ring main uint}

The present invention relates to an airtight container reinforcement for a ring main unit, and more particularly, to an airtight container reinforcement for a ring main unit capable of preventing deformation due to gas injection or welding in the airtight container.

In general, various switch gears such as load switch, circuit breaker, and disconnector are applied to the airtight container in the ring main unit.

The ring main unit plays a role of energizing and opening/closing a load and blocking an accident current in the distribution system.

In the hermetic container or tank of the ring main unit, SF6 gas, an insulating medium, is injected under a certain pressure for accident current and load opening and closing, and is used in the injected state.

Conventionally, in order to inject SF6 gas into the hermetic container, a vacuum operation is performed in advance to remove the air inside the hermetic container, and then the gas is injected.

At this time, the hermetic container is subjected to a vacuum pressure lower than atmospheric pressure.

In addition, the airtight container is subjected to a pressure greater than atmospheric pressure due to an increase in internal pressure due to injection of SF6 gas. Accordingly, the hermetic container can be deformed.

The airtight container modified as described above causes a problem in that the operation of the various switch gears attached as described above is not smoothly performed.

For this reason, in the related art, there is a problem in that the function of each switchgear is not properly implemented, resulting in a malfunction resulting in an electric accident.

However, as shown in Figs. 2 and 3, the conventional reinforcing material 1 is a sheet metal material formed by bending. Usually, the cross section of the reinforcing material has a shape of c. In addition, the corner portion of the bent reinforcing material 1 has a round shape.

The reinforcing materials 1 forming the corners of the round shape are in contact with each other and weld the welded portion to fix the vertical and horizontal reinforcing materials to each other.

However, during the welding process, the force of pulling the vertical reinforcing members on both sides may be generated due to the gap generated by the round shape.

Since the reinforcing material 1 is formed of a stainless steel plate, there is a problem in that the reinforcing material 1 is warped, and as a result, welding deformation in the direction of the arrow in FIG. 3 occurs when the airtight container is manufactured.

Furthermore, conventionally, there is a problem in that the operation of the switch gear becomes unstable and defects occur due to the welding deformation generated during the manufacture of the hermetic container 10.
