Abstract
193,231. North, N. E., and Metropolitan- Vickers Electrical Co., Ltd. Jan. 11, 1922. High-potential switches; switchboard details; magnetic blow-outs.-One of the contacts 3 of a contactor switch unit is connected by a flexible conductor 34 to a terminal 42 mounted on a member which forms no part of the switch unit, for example a member 38 of the framework upon which the switch unit is mounted. The other contact 2 may be connected similarly or to a terminal 19 mounted on the switch unit. The Figure shows a switch unit mounted side by side with others on a framework which comprises common horizontal bars 13, 14 and 38. The switch, which comprises contacts 2, 3, arcing-horns 4, 5, arcing- shoot 6 and blow-out coil 7, is actuated pneumatically by a piston rod 30 in a cylinder 8, the movable contact 3 being fixed to a bracket 27 pivoted to a bracket 28 attached to a block 29 mounted on the piston rod 30, and a spring 31 between brackets 27 and 28, ensuring a rubber contact. The contact 3 is connected by the conductor 34 to a fork-shaped terminal block 37 clamped on the bar 38 of the framework. The contact 2 is connected through the blow-out coil 7 to the terminal 19.
