Title: Improvements in electric disconnecting switches
IPC: H02B1/00
Filed: 1936-10-27
Abstract: 483,996. Gas-blast switches. BRITISH THOMSON - HOUSTON CO., Ltd. (Allgemeine Elektricitats -Ges.) Oct. 27, 1936, No. 29182. [Class 38 (v)] In a disconnecting switch of the air break type in which contact separation is accompanied by a gas blast led through an annular passage surrounding one of the co-operating contacts, the wall of the passage is provided with an extension which is turned back over the wall to constitute a corona shield around the contact. In the construction shown in Fig. 2, the shield 1 is carried by a sleeve 7 which is displaceably arranged around the pin contact 3 against the action of a spring 8. The sleeve 7 is slidable in a guide 12 fitted on the insulator 10 which is used for conveying compressed gas. The co-operating contact 23 is surrounded by a shield 11 supported on one end of a double-armed lever 13 rotatable about a point 9. The other arm of the lever carries a similar shield and contact co-operating with a further contact similar to the contact 3. In another construction, Fig. 3, the pin contact 3 is mounted on a piston 34 slidable in a cylinder 50 against the action of a spring 18. The gas blast is introduced into the annular passage between the guide piece 2 and the contact 3, the guide piece having a nozzleshaped and connected to the shield 1. The co-operating contact 33 is provided with a similar shield 11. In opening the circuit the shields 1, 11 remain in contact until the gas pressure has forced back the piston 34 to separate the contacts, after which the shield 11 with the contact 33 is moved away to provide a wide air gap between the contacts. In a modification, Fig. 4 (not shown), the shields are slidably mounted and pressed towards each other by springs, so that the shields do not separate until the contacts have moved a considerable distance apart. The compressed gas may serve for actuating the contacts as well as for quenching the arc. In the construction shown in Fig. 10, the disconnecting switch serves as a power switch, and comprises two swivelling arms 44, 45 terminating in the shields 1, 11 which accommodate the nozzle-shaped guide pieces. The arms are carried by rotatable insulators 52, 56 driven by means of toothed rims 65, 66 from driving devices 68, 64 connected to compressed gas conduits 69, 70. The gas blast is fed to the rotatable insulators. In a modification, Fig. 13, the swivelling arms 37, 57 carrying the power switch contacts in shields 11, 1 have backward extensions 47, 67 carrying contacts 58, 59 which co-operate with disconnecting contacts 53, 43 on fixed insulators. In switching off, the circuit is first broken at the power switch contacts in the shields 11, 1. In the fully open position shown, the platform 60 carrying the switchgear can, after loosening the gas connections, be moved away in the direction of the arrow 71, the platform being mounted on rollers for this purpose.
