Abstract

1,126,362. Vacuum switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 24 June, 1966 [6 July, 1965], No. 28597/65. Heading H1N. A circuit-breaker has main contacts 1, 4, in insulating fluid and auxiliary contacts 16, 18, connected in parallel, the contacts 16, 18 being arranged to open after main contacts 1, 4 have opened, and to close before contacts 1, 4 have closed, and the contacts 16, 18 being accommodated in an evacuated space, i.e. the auxiliary contacts forming a vacuum switch 14. An actuating rod 81 of insulating material is pivoted at 9 to the movable contact carrying arm 23 which is pivoted at 5, a cam surface 24 of arm 23 engaging an abutment 22 on an operating rod 19 of the vacuum switch 14, after an initial opening movement of the main contact 4, to open contacts 16, 18. A spring 25 recloses the vacuum switch 14 before rod 81 recloses main contacts 1, 4. The circuitbreaker may be double- or three-pole and has conventional trip mechanism, and may be operated manually. The main contacts open in oil, liquid insulant or insulant gas such as SF 6 .
