Abstract

PURPOSE: To provide a non-combustible, compact and durable device, by using a changeover switch which uses a vacuum valve as current switching element and enclosing it in low-pressure non-combustible gas.
CONSTITUTION: Transformer proper 3 and tap selector 4 are enclosed in transformer proper tank 5, which is filled with non-combustible high-pressure insulating gas 6. Changeover switch 12, which uses vacuum valve 11, is enclosed in changeover switch chamber tank 14, which is filled with low-pressure insulating gas. Tap selector 4 and changeover switch 12 are connected by means of bushing 16, which projects into tank 5 of the transformer proper and changeover switch chamber tank 14. Further although not shown, an airtightness partition is provided between insulating gas 6 inside changeover switch chamber tank 14 and the atmosphere. The partition is displaced by the pressure difference between the two, and thereby the pressure of insulating gas 6 is automatically balanced with the atmospheric pressure.
