Reduced Voltage Starters

Transcription

1 Reduced Voltage Starters ontrolled starting for low in-rush and smooth operation Sprecher + Schuh reduced voltage starters are designed for starting squirrel cage induction motors where the starting current of a motor is likely to exceed local power company restrictions, interfere with plant operations or where the load may be damaged by high starting torques. Starting with the best All Sprecher + Schuh reduced voltage starters feature our AT7 and AT9 line of motor starters. These compact starters offer intermediate sizes to better match specific motor requirements. This equates to generous wiring space and less wasted horsepower capacity. Our advanced EP7 solid state overload relays are used with starters. See Section B in this catalog for a full description of these excellent motor protection relays. hoosing the right reduced voltage method Autotransformer Starter At starting, three autotransformers (one for each phase) are automatically connected in series with the motor. The voltage at the motor is reduced to either 50%, 65% or 80% depending on which voltage tap was selected. After a timed interval, a contactor connects the motor across-the-line and shorts out the autotransformers. Factory standard autotransformers are rated for medium duty as defined by NEA. Part Winding Starter This type of starting requires that the motor winding be in two equal parts, and that at least six terminal leads be provided on the motor. At starting, the controller is arranged to connect one section of the winding to the supply lines. After a timed interval, a second contactor connects the other section of the motor winding to the supply lines, in parallel with the first. Wye-elta Starter This type of starting requires a special wye-delta motor. Both ends of the motor s three windings are brought out so they are accessible for reconnecting from wye to delta. At starting, the controller connects the motor in the wye configuration. After a timed interval, a second contactor connects the motor in a delta configuration. The reference chart below compares all three reduced voltage starting methods and contrasts them with across-theline starting.
