A kind of motor soft starter; comprise control circuit module, power trigger circuit module, power device module, binding post and overtemperature protection module; described control circuit module is electrically connected with power trigger circuit module, power device module and binding post successively; described soft initiator also comprises the current-voltage sampling module for the current of electric voltage sample; described current-voltage sampling module is electrically connected with binding post, control circuit module and overtemperature protection module respectively, and described overtemperature protection module and control circuit module are electrically connected.
Preferably, described soft initiator also comprises overcurrent protection module, overvoltage protective module and open-phase protection module, and described overcurrent protection module, overvoltage protective module and open-phase protection module are electrically connected with control circuit module and current-voltage sampling module respectively.
Preferably, described control circuit module is provided with Ethernet interface.
Be compared to prior art; motor soft starter of the present utility model has real-time overcurrent, overvoltage, overheated and default-phase protection function; each functional module is judged overcurrent, overvoltage, overheated or phase shortage possibility by sample rate current or the voltage of current-voltage sampling module; and by the protective effect of control circuit module practical function, have the integrated level height, intelligent high, volume is little, maintenance is flexible, the easy characteristics of adjustment and installation.
Description of drawings
Fig. 1 is the structured flowchart of the utility model motor soft starter.
Embodiment
Further describe the utility model below in conjunction with drawings and Examples, but protection range of the present utility model is not limited to this.
With reference to Fig. 1, motor soft starter of the present utility model comprises control circuit module, power trigger circuit module, power device module, binding post, power module, current-voltage sampling module, overtemperature protection module, overcurrent protection module, overvoltage protective module and open-phase protection module.Described control circuit module, power trigger circuit module, power device module and binding post are electrically connected in turn, and the two ends of its middle connecting terminal link to each other with motor with power module respectively.Described control circuit module also is electrically connected with current-voltage sampling module, overtemperature protection module, overcurrent protection module, overvoltage protective module and open-phase protection module respectively, and described current-voltage sampling module is electrically connected with overtemperature protection module, overcurrent protection module, overvoltage protective module and open-phase protection module respectively.Described control circuit module is provided with Ethernet interface, can connect host computer by Ethernet interface, realizes the remote online monitoring function.
Described control circuit module, power trigger circuit module, binding post, power module, current-voltage sampling module, overtemperature protection module, overcurrent protection module, overvoltage protective module and open-phase protection module integration arrange, and volume is little, and it is little to take up room.During motor soft starter work; under the control of control circuit module; electric current and the voltage of current-voltage sampling module real-time sampling input end of motor; the electric current that samples and voltage are delivered in overtemperature protection module, overcurrent protection module, overvoltage protective module and the open-phase protection module to be judged; if sampled value surpasses preset value; then this protection module sends command information to the control circuit module; by work or the disconnection of control circuit module realization motor soft starter, play the function of real-time overload protection.
Wherein overtemperature protection module, overcurrent protection module, overvoltage protective module and open-phase protection module are realized by the concrete circuit with corresponding function, can realize the electric current comparing function by comparator and respective peripheral circuit such as overcurrent protection module, when electric current surpasses threshold value, comparator will be exported Different Results, impel the disconnection of control circuit module controls motor soft starter, this concrete circuit design belongs to prior art, does not repeat them here; The physical circuit design of other protection module can with reference to the operation principle of stream protection module, not repeat them here.
