Abstract
975,137. High voltage switches. J. L. GRATZMULLER. April 4, 1962 [April 6, 1961; March 21, 1962], No. 12972/62. Heading H2B. A circuit breaker has a contact member 54 movable into engagement with a fixed contact 56 against a spring 80, by means of an hydraulic actuator 64 acting on an insulating force transmitting rod 70, the spring 80 maintaining the rod 70 always in a state of tension. The hydraulic actuator 64, which may be of the kind disclosed in Specification 777,750 is at earth potential and is separated from the breaker by an oil-filled insulator column 66 maintained under permanent compression by a tensioned member 90 as is disclosed in Specification 953,575. The rod 70 moves the contact 54 through a double rack and pinion gearing 72- 78 under the control of a dashpot 88. The switch chamber 52 is sealed from the dashpot chamber 110 and these contain different grades of oil. In an alternative form (Fig. 2) the insulating rod 35 is maintained in compression by spring 28. In another modification (Fig. 1, not shown) the gearing 72-78 is replaced by a linkage.
