Title: Improvements relating to electric switchgear
IPC: H01H9/20
Filed: 1924-01-19
Abstract: 229,065. Cox, F. B. Jan. 19, 1924. Switchboards; sliding switch-carriage arrangements; oil switches; covers and lids; switch mechanism interlocking with lids. - Relates to interlocking gear for electric switchgear panels having the main switch with a removable oil tank mounted in front of a hollow stand forming a compartment for enclosing the isolating switch and a compartment for enclosing the instrument transformers and other auxiliary gear, this compartment being fitted with a hinged door which is interlocked with the main and isolating switches. As shown in Fig. 1, the stand A forms a chamber for the auxiliary gear provided with a hinged door a' and a compartment a<2> for the isolating switch F having a separate door a<3>. The main switch is operated by a spindle C in a casing B and is provided with a removable oil tank D. A locking bar E is pivotally attached at one end by links e<1>, e<2> to the door a<1> and has at the other end a slot e<3>, terminating in enlarged ends e<4>, e<5> through which passes a portion of the shaft C of rectangular section thereby permitting operation of the main switch with the bar E in its extreme positions but ensuring that the switch is off while the bar is moving between these positions. The opening and closing of the door a<1> operates the isolating switch F, which may be connected to the door by links f<1>, f<2>, Fig. 5, or may comprise fixed contacts bridged by a contact F<1> carried by the door. Thus the main switch is necessarily open during the opening of the isolating switch. To prevent the lowering of the tank D before this occurs it is provided with a vertical bar d<1> terminating in lateral projections d<2>, d<3> embracing the bar E, Fig. 4<a>. When the bar E is in the position shown in Fig. 2 a recess e<6> is now opposite the bar d<1> so that the tank D may be lowered. To prevent the isolating switch being reclosed before the tank is replaced the portion e<4> of the slat e<3> is shaped so that as the support of the lower projection d<3> is removed from the bar E it turns about its pivot e<7> to the position shown in Fig. 3 and is only raised again when the tank is replaced. Although the isolating switch cannot be reclosed with the bar E in this position, the main switch may be closed for trial purposes. A modified form of the above interlocking arrangements is also described in which the main switch spindle carries projections co-operating with other suitable projections on the sliding locking bar to effect similar interlocks. As applied to trucktype switchgear, Figs. 10 and 11, one end of the locking bar E<2> is pivoted in the stationary part A the bar extending into the movable casing B<2> bearing the isolating contacts f<2>, f<3>. The door a' is held closed while these contacts are in engagement by a rotatable locking cam e<10> engaging a recess e<15> in a bar e<11> and operated by links e<12>, e<13> pivotally attached at e<14> to the truck member.
