Variable-voltage variable-frequency elevator control apparatus

A variable-voltage variable-frequency elevator control apparatus is disclosed in which a circuit for the consumption of regenerated power produced during regenerative braking is provided on the DC side of the apparatus rather than on the AC side. During regenerative braking with an emergency generating unit in operation, regenerated power is consumed by the consumption circuit on the DC side of the circuit and is prevented from being returned to the emergency generating unit. This prevents the production of voltage notches commonly produced during regenerative braking by thyristor commutation in conventional circuits. Because no voltage notches are produced, a reduction in the size of the emergency generating unit can be achieved. In addition, since it consumes DC power rather than 3-phase AC power, the consumption circuit requires fewer elements than in conventional control apparatuses.

Method and detection system for monitoring the speed of a lift cage

Abstract: In this method the speed of a lift cage is monitored. In the case of excess speed caused by brake failure of the motor brake or shaft fracture of the drive pulley shaft the safety circuit is opened and the detection system is transferred from the normal operational state (circle with a 1) to the retardation state (circle with a 2) in which it is monitored whether the lift cage is retarded after defined speed presets. After a successful retardation the detection system is transferred to the state of standstill monitoring (circle with a 3) in which it is monitored whether the lift cage leaves its standstill position. If the presets of state 2 or state 3 are not fulfilled, the detection system is transferred to the braking state of the brake (circle with a 4) in which a brake which fixes the lift cage is activated.

Inverter power transistor protection

An elevator system is powered by a multiphased motor to which power is supplied from an inverter, which is powered by a battery. The collector-emitter voltage across the output transistors in the inverter is sensed as the transistors are turned on, and if the voltage does not drop to the saturation voltage within a certain time, the drive to the inverter is discontinued. If at any time while the transistors are in saturation saturation voltage rises, the drive is turned off. To start the drive, the transistors are permitted to turn on for a short interval of time. If, following that interval of time, the saturation voltage is not correct, the drive is turned off. The inverter has separate sections for driving each winding of the motor, and each of these sections has a separate power supply and fault detection circuit, which operates to measure the saturation voltage across the transistor and provide a fault signal which indicates that the drive should be terminated.
