Abstract
The utility model discloses a switching device, which is characterized in that the output terminal of a power supply is connected with the input terminal of a handcart cabinet S; the output terminal of the handcart cabinet is connected with the high-voltage terminal of a transformer B; the transformer B outputs two paths of AC power supply to be connected with change-over switches K1, K2; the upper ends of the change-over switches K1, K2 are connected in parallel with the input terminals of frequency converters A, B; the output terminal of the frequency converter A is connected with the change-over switch K1; the middle ends of the change-over switches K1, K2 are connected with a motor. The utility model has the advantages that the transformer is connected with the motor by change-over switches, so when the frequency changer coverts go wrong, the transformer is connected with the motor by the change-over switches, the motor can directly starts, guaranteeing normal production.
Description
The utility model belongs to confession, power distribution equipment field, particularly a kind of switching device shifter that is used for Industry Control.
In industrial production, frequency converter often uses as automatic control equipment.When frequency converter breaks down or frequency converter need overhaul the time, automatic control system can only be shut down maintenance, can not work, and what influence was produced normally carries out.
The purpose of this utility model provides a kind of switching device shifter.It can break down or frequency converter switches need overhaul the time at frequency converter, makes the automatic control system operate as normal, and what guarantee to produce carries out normally.
For reaching above-mentioned purpose, the output of power supply that is characterised in that of the present utility model is connected with the input of handcart cabinet S, and the output of handcart cabinet S is connected with the high-pressure side of transformer B, transformer B output two-way AC power and switching lock K
