Abstract
The present invention is characterized in that, when producing a vacuum interrupter, an aligning member for aligning between an insulating container, a moving side seal cup and a fixed side seal cup is separately provided so as to be located at a more accurate position when the insulating container is connected to the moving side seal cup or the fixed side seal cup So that the position of the insulating container, the moving side seal cup, and the fixed side seal cup can be precisely adjusted without using a separate aligning jig.
Description
The present invention relates to a vacuum interrupter, and more particularly, to a vacuum interrupter in which an alignment member is provided in a vacuum interrupter to simplify the production process of a vacuum interrupter.
Generally, a breaker is an electric protective device that protects a load device and a line from such a fault current in the event of a short circuit or a ground fault which may occur in an electric circuit.
The circuit breaker is composed of an inflow circuit breaker using oil as a soot medium according to the SOHO medium, a gas circuit breaker using an inert gas sulfur hexafluoride (SF6) gas, an air circuit breaker using air as a soot medium, And vacuum breakers used.
Currently, most electric power equipment products use arc fluoride and sulfur hexafluoride gas with excellent insulation performance as insulating medium. However, the greenhouse effect of sulfur hexafluoride gas is 23900 times that of carbon dioxide, which is designated as global warming gas by the Kyoto Protocol and is being regulated worldwide. In Korea, environmentally friendly electric power equipment products that can substitute for sulfur hexafluoride gas are being actively developed. Demand for vacuum interrupters is rapidly increasing as one of such environment friendly electric power equipment products.
Vacuum circuit breaker is a device that protects circuits and equipment by quickly isolating the circuit by extinguishing arc generated in case of normal load switching and fault current interruption in a vacuum container. The key part that interrupts the current in the vacuum circuit breaker is a vacuum interrupter .

The present invention relates to a vacuum interrupter, and more particularly, to a vacuum interrupter in which an alignment member is provided in a vacuum interrupter to simplify the production process of a vacuum interrupter.
The object of the present invention is to provide a method of manufacturing a semiconductor device, which comprises an insulating container, a fixed-side solid cup which is fastened to the upper portion of the insulating container and through which the fixed electrode penetrates, and a vacuum The interrupter is provided with an aligning member between the insulating container and the movable side seal cup and between the insulated container and the fixed side seal cup to align the connection position of the insulating container with the movable side seal cup and the fixed side seal cup. A vacuum interrupter is provided.
The aligning member may have a ring shape and may include a body portion having an outer circumferential surface in close contact with an inner circumferential surface of the movable side seal cup or the fixed side seal cup to align the positions of the movable side seal or the fixed side seal; A protrusion formed to protrude downward from the main body and having an outer circumferential surface in close contact with an inner circumferential surface of the insulating container to align the position of the insulating container; And a side portion protruding outward from the main body portion and positioned so that the insulating container and the movable side seal or the insulating container and the fixed side seal are in close contact with each other.
And the lower surface of the protrusion is rounded.
And the width of the body in the horizontal direction is longer than the width of the projection in the horizontal direction.
And the outer end of the side portion is located at a predetermined distance inward from the outer end of the insulating container when the aligning member is in close contact with the insulating container.
And the space portion is formed in the main body portion so that a filler for welding is inserted between the main body portion and the movable side seal cup or the fixed side seal cup when the main side seal portion or the fixed side seal portion is placed in close contact with each other .
Further, the space portion is opened on the upper side.
The insulating container may be made of a ceramic material.
And the alignment member is an oxygen-free copper material.
As described above, the vacuum interrupter of the present invention is provided with an aligning member for aligning between the insulating container, the movable side cup and the fixed side seal cup separately during production of the vacuum interrupter, So that the position of the insulating container, the moving-side seal cup, and the fixed-side seal cup can be precisely adjusted without using a separate aligning jig.
In addition, since a separate alignment fixture is not used, the time required for installation and disassembly of the alignment fixture is not required in the production of the vacuum interrupter, and the production time is shortened.
In addition, since an alignment jig is not used, the production process is simplified.
Further, by using an alignment fixture, it is possible to prevent the alignment fixture from being welded to other components during braze welding, and to improve the quality of the produced vacuum interrupter.
