The output end of the input coil is connected with the input ends of the alternating-current contactors. The output ends of the alternating-current contactors are connected with the input end of the transformer. The input end of the intelligent control device is connected with the output end of the input coil. The output end of the intelligent control device is connected with the alternating-current contactors to control the on/off states of the alternating-current contactors. According to the above-mentioned structure, the alternating-current contactors comprise three gears corresponding to different voltage ranges respectively, the intelligent control device is used to perform voltage sampling on the input coil through a voltage sampling unit, and then the sampled voltage is compared with the reference voltage of each gear (through a voltage comparing unit), and then on/off control is performed on a corresponding alternating-current contactor through an on/off control unit, so that automatic control can be realized, and the safety can be improved.
Description
Technical field
The utility model relates to a kind of appliance field control device, especially a kind of intelligently voltage boosting cabinet.
Background technology
Traditional soft-start cabinet, application principle is to reach certain value when electric current, then starts, if voltage jump, load is easy to damage so, or cause trip phenomenon, therefore, when electric current reaches certain value, A.C. contactor can be closed, when electric current drops to after certain value, A.C. contactor can disconnect, and with such action, realizes level and smooth startup.
But the existing cabinet that boosts when voltage fluctuation, the transformer coil that can not automatically switch, when lower voltage, if switching transformer coil not in time, output voltage is on the low side, electric current is bigger than normal, may cause that transformer and motor burn out; When voltage raises, if switching transformer coil not in time, output voltage is higher, may cause that transformer and electrical machine insulation puncture, and fail safe is not high.
And current adjusting normally realizes by manual control, that regulates time delay more serious, is not to be therefore applicable to the existing market demand
Summary of the invention
The purpose of this utility model is, a kind of automatic adjusting, safe intelligently voltage boosting cabinet are provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of intelligently voltage boosting cabinet, comprise input coil, A.C. contactor, transformer, the output of input coil is connected with the input of A.C. contactor, the output of A.C. contactor is connected with the input of transformer, also comprise intelligent controller, the input of intelligent controller is connected with the output of input coil, and the output of intelligent controller is connected with A.C. contactor, controls the break-make of A.C. contactor.
Of the present utility modelly further be set to: intelligent controller comprises voltage sample unit, voltage comparison unit, on-off control unit, voltage sample unit is connected as the input of intelligent controller and the output of input coil, on-off control unit is connected with A.C. contactor as the output of intelligent controller, the output of voltage sample unit is connected with the input of voltage comparison unit, and the output of voltage comparison unit is connected with the input of on-off control unit.
Of the present utility modelly further be set to: A.C. contactor comprises third gear, be respectively one grade of A.C. contactor, second gear A.C. contactor, third gear A.C. contactor, the input of the input of the input of one grade of A.C. contactor, second gear A.C. contactor, third gear A.C. contactor is connected with the output of input coil respectively, and the output of the output of one grade of A.C. contactor, second gear A.C. contactor, the output of third gear A.C. contactor are connected with transformer respectively.
Of the present utility modelly further be set to: one grade of A.C. contactor, second gear A.C. contactor, third gear A.C. contactor are connected with on-off control unit respectively.
Said structure is divided into third gear by A.C. contactor, the voltage range section that difference is corresponding different, then intelligent controller carries out voltage sample by voltage sample unit to input coil, then compare (passing through voltage comparison unit) with the reference voltage of each gear, then by on-off control unit, corresponding A.C. contactor is carried out to break-make control, thereby realize automatically, control, improve fail safe.
