Definitions
- a common form of distribution switchgear for voltages up to 36 kilovolts incorporates circuit breakers of the oil-filled type isolated from fixed units by vertical withdrawal. This range of switchgear also incorporates non-automatic load break switches and, especially for voltages of 12 kilovolts and lower, ring main equipment incorporating at least three switch functions to control, for example, a transformer and two ring main cables.
- a conductor 5 passes through the bushing 3 and carries on its end within the housing 2 a transverse contact support arm 6 which carries resilient contact fingers 7, and a support member 8 which carries a field coil 9.
- a conductor 10 passes through the bushing 4 and carries on its end within the housing 2 a mounting 11 on which a mowable contact arm 12 of circular cross-section is mounted for angular movement about a pivot 13.
- a flexible, electrically conductive strap 14 connects the contact arm 12 to the conductor 10 for the passage of most of the load current therethrough, the strap 14 being connected to the conductor 10 by way of an L-shaped copper bracket 15 and being bolted to the contact arm 12.
- the contact arm 12 can be mounted on the end of the conductor 10 by means of a spring loaded pivot through which the load current passes in use.
- a fourth switch can be provided which shares the field coil and arcing electrode of the tee-off switch 201 c in the same manner as described above in relation to the ring main switches 201a a and 201b. Again, a mechanical interlock will be used to prevent simultaneous opening of the switches.
- Reference 233 shows in broken line the manner in which a conductor and bushing for the fourth switch would be arranged on the housing 202.
- the contact arms on the embodiments of Figures 1 to 10 can be of rectangular cross-section, and the field coil and arcing electrode can be of oval cross-section.
- the invention has other applications besides the distribution switchgear described above. It is applicable to the control of industrial circuits and to distribution and transmission circuits at higher voltages. It can also be supplied to circuit breakers and switches having an insulated enclosure.
