Abstract
The utility model relates to a motor soft starter device, in particular to the motor soft starter device used for one motor for operation and one for spare. The device comprises two circuits which are formed by connecting two motors with a soft starter in series and are controlled by two switches, and the two circuits are connected in parallel. Compared with the prior art, the device has various soft start modes, such as current-limiting start, voltage slope start, slope plus current-limiting start, kick torque start and the like, adopts a unique arithmetic so as to ensure the motor start more stable and accurate, has various parking manners, such as soft parking, free parking, and braking, and is provided with good anti-jamming performance. And all the input and output signals are isolated and adopt different anti-jamming grades so as to be used in special industrial environments.
Description
[technical field]
The utility model relates to a kind of electric machine soft starting apparatus, especially a kind of electric machine soft starting apparatus that motor is standby of a motor operation that is used for.
[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, increase a standby motor soft starter.
For achieving the above object, design a kind of standby electric machine soft starting apparatus, have multiple soft-start mode: current limit starting, voltage ramp starting, slope add modes such as current limit starting, kick torque starting.Adopt unique algorithm, make electric motor starting more steadily, accurately.Multiple parking mode: soft stop, free parking, braking brake.Powerful anti-interference: all inputs, output signal are all isolated, and have adopted different anti-interference ranks, use to adapt in special industrial environment.Unique two-parameter function: possess two cover different capacity Electric Machine Control parameters simultaneously, the motor of two different capacities of may command.Have protection and Presentation Function: omnidistance detect parameters such as voltage, electric current, power, and have defencive functions such as stall, inverse-time overcurrent, overload, overheated, phase shortage.Output function is sent in change able to programme: the user can set up on their own to become and send output type (electric current, active power, power factor etc.) and change to send output area.Phase sequence recognition function: detect phase sequence automatically, adjust the silicon controlled triggering signal, guarantee that soft starter can operate as normal when the phase sequence wrong.
The technical scheme that its technical problem that solves the utility model adopts is: the start mode that adopts current limit starting, voltage ramp starting, kick torque starting; the parking mode of soft stop, free parking, braking brake; omnidistance detect parameters such as voltage, electric current, power, and have defencive functions such as stall, inverse-time overcurrent, overload, overheated, phase shortage.
The beneficial effects of the utility model are, the LCD liquid crystal display, Chinese/menu in English can show multi-picture, display frame can be set, parameter is provided with simply, debugging easily, and multiple mounting means: but one is installed, 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.
