Title: Improvements in arrangements for automatically interconnecting adjacent sections of trolleybus, tramway, and other electric distribution systems
IPC: H01H83/14
Filed: 1936-06-30
Abstract: 472,506. Protective cut-out arrangements. EDWARDS, W. V., and CUNUDER, F. J. June 30, 1936, No. 18066. [Class 38 (v)] Means for automatically interconnecting adjacent sections 1, 2 of a trolley bus, tramway, or other distribution system which are arranged to be energized by separate feeders from the same or different sources, comprises a circuitbreaker which is adapted to be held mechanically in closed position and to be opened when abnormal conditions occur in the system by a trip coil, and has a closing coil the circuit of which is controlled by a switch arranged to be held open when the voltage of either section in the insulated condition exceeds that of the adjacent section by a given value and to prevent the closing coil being energized, the switch being arranged to close when the voltage difference between sections is equal to or less than a given value. The breaker contacts C1, C2, are in series with the trip coil TC between the sections 1, 2, between which is also connected a relay coil RC. When TC is sufficiently energized, it attracts armature A3 and, by means of arm E, lifts a latch L clear of a roller R on an arm X, which thereupon moves forward rotating a spindle M and moving the arm CA carrying the contact C2 to open position. A rearward extension of X lifts a rod, which operates a counter V and also raises an arm Q clear of a spring S on an armature A2, which is pivoted at P and biassed by weight W into a position in which a mercury switch MS carried on the armature is closed. If, however, the voltage difference between the sections 1, 2 is above, say, 10 volts, the coil RC maintains the armature in the position in which MS is open, but when the difference falls below that value, MS closes and energizes the closing coil MC which attracts the armature A1 and recloses C1, C2, resetting latch L and, by means of Q, reopening MS to de-energize MC.
