Abstract
The utility model relates to a motor soft starter device, in particular to a motor soft starter device of two-use-and-one-spare. The device comprises three circuits which are formed by connecting three motors with a soft starter in series, controlled by two switches, and connected in parallel. Compared with the prior art, the motor soft starter device adopts three motors, if two of the motors break down, the spare motor can carry out operation automatically with time delay, and after the faults of the breakdown motor are removed, the spare motor becomes spare automatically.
Description
[technical field]
The utility model relates to a kind of electric machine soft starting apparatus, the especially a kind of dual-purpose one electric machine soft starting apparatus that is equipped with.
[background technology]
At present, known soft-starter control function and imperfection and lack a lot of defencive functions, as the impact of the electric current in motor starting, the stopped process, net capacity height, impact of machinery etc. during electric motor starting.For example as most widely used squirrel cage asynchronous motor, it adopts the condition of reduced voltage starting: the one, and during motor starting, machinery can not bear the impact torque of direct-on-line starting; The 2nd, during motor starting, its terminal voltage can not satisfy code requirement; The 3rd, during motor starting, influence the normal operation of other loads.
[summary of the invention]
In order to overcome the deficiency of present motor soft starter; the utility model relates to a kind of dual-purpose one electric machine soft starting apparatus that is equipped with that is used for; after being applied to two electrical faults shutdown, then standby motor time-delay puts into operation automatically, then transfers to standby after the fault of fault motor is got rid of automatically.Three soft initiators in this device are provided with and independently start stop button.Then another transfers to standby automatically to start any two motors.Every soft initiator is equipped with a key panel, the running current, the fault state that be used to that parameter is set, show motor.This control device also is reserved with control start-stop input contact far away, operation output contact, fault output contact.
The technical scheme that its technical problem that solves the utility model adopts is: this device is equipped with three soft starters, every soft initiator is provided with and independently starts stop button, then another transfers to standby automatically to start any two motors, three soft initiators motor of connecting respectively, three motor parallels in circuit, every soft initiator is equipped with a key panel, the running current, the fault state that be used to that parameter is set, show motor.
The beneficial effects of the utility model are, the LCD liquid crystal display, and Chinese/menu in English can show multi-picture, display frame can be set.Parameter is provided with simply, easily debugging.Multiple mounting means: but the one installation, but also partial installation.Wherein partial installation can be installed separately control module and display module, is convenient to remote operation and supervision.
[description of drawings]
Fig. 1 is primary circuit figure of the present utility model.
[embodiment]
When using the soft initiator actuating motor, the output voltage of thyristor increases gradually, and motor quickens gradually, and up to the full conducting of thyristor, motor is operated on the mechanical property of rated voltage, realizes smoothly starting, and reduces starting current, avoids starting overcurrent tripping.When treating that motor reaches rated revolution, start-up course finishes, soft initiator replaces the thyristor of having finished the work from employing bypass contactor, for running well, motor provides rated voltage, to reduce the thermal losses of thyristor, prolong the useful life of soft initiator, improve its operating efficiency, make electrical network avoid harmonic pollution again.Soft initiator also provides the soft stop function simultaneously, and soft stop is opposite with soft start-up process, and voltage reduces gradually, and revolution drops to zero gradually, the torque shock ends of avoiding free parking to cause.
