Abstract
The utility model provides a soft starter adaptable to a plurality of voltage classes, which comprises a bypass contactor and a soft start main control board. The bypass contactor comprises an alternating current contactor; a triggering module is connected in parallel with the alternating current contactor; the soft start main control board is provided with a voltage detection module, a controller, a driving circuit and a current detection module electrically connected; and a display module and an input module are connected onto the controller. Thus, the problem of universality for different soft starters in the prior art can be solved.
Description
Technical field
The utility model relates to electricity field, refers to especially a kind of soft starter that adapts to multi-voltage grade.
Background technology
In prior art, to multiple voltage, adopt different soft starters.Do not have versatility, user cost is high.Under superpressure or undervoltage condition, soft starter can be reported to the police, and causes using; Under special circumstances, even can cause soft starter to burn.
Utility model content
The utility model proposes a kind of soft starter that adapts to multi-voltage grade, solved the versatility problem of different soft starters in prior art.
The technical solution of the utility model is achieved in that
A soft starter that adapts to multi-voltage grade, it comprises bypass contactor and soft start master control borad; Described bypass contactor comprises an A.C. contactor, and described A.C. contactor is parallel with trigger module; The voltage detection module, controller, drive circuit and the current detection module that on described soft start master control borad, are provided with electrical connection, be connected with display module and input module on described controller.
During use, three-phase AC power supplies is carried out voltage detecting by described voltage detection module, the data feedback of three-phase voltage detected in described controller, and described controller shows Voltage-output to display module; User can be according to the operating voltage grade of the voltage setting circuit detecting, and is preserved by described controller.After electric pressure arranges, described controller transmission enabled instruction to trigger module, makes motor operation through described drive circuit.When motor total head is moved, trigger switch KM adhesive.
Preferably, described input module comprises keyboard or button; Described display module is display screen.
The utility model can first detect the magnitude of voltage of access, and according to the electric pressure of this magnitude of voltage setting work, has solved the versatility problem of different soft starters.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the circuit link block figure of the soft starter embodiment of the utility model band built in bypass.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the soft starter with built in bypass of the present utility model comprises starter shell, is provided with bypass contactor and soft start master control borad, i.e. master control borad described in Fig. 1 in described shell; Described bypass contactor comprises an A.C. contactor, and described A.C. contactor is parallel with trigger module; The voltage detection module, controller, drive circuit and the current detection module that on described soft start master control borad, are provided with electrical connection, be connected with display module and input module on described controller.
During use, three-phase AC power supplies is carried out voltage detecting by described voltage detection module, the data feedback of three-phase voltage detected in described controller, and described controller shows Voltage-output to display module; User can be according to the operating voltage grade of the voltage setting circuit detecting, and is preserved by described controller.After electric pressure arranges, described controller transmission enabled instruction to trigger module, makes motor operation through described drive circuit.When motor total head is moved, trigger switch KM adhesive.
For example: 380V three-phase AC power supplies is carried out voltage detecting by voltage detection module, and the three-phase voltage that detects of judgement whether reach set point 380V.If the voltage detecting is not in the scope of 380V ± 20%, soft starter starting protection, cannot start circuit.After in the voltage access controller that meets set point, controller inputs to display module by voltage and shows; By this electric pressure of keyboard input 380V, controller carries out data preservation again, and electric pressure setting completes.Described controller send again enabled instruction through described drive circuit to trigger module, trigger module is received enabled instruction, triggering and conducting makes motor operation.When motor total head is moved, built-in signal relay output, trigger switch KM adhesive, bypass contactor drops into and automatically by continuous service, and at this moment trigger module is still in running status but do not have electric current to pass through it, and electric current is by the complete trigger switch KM that all flows through.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
Claims (3)
