Abstract
The utility model provides a soft starter with a built-in by-pass, which comprises a starter shell. The shell is internally provided with a by-pass contactor and a soft-start main control board; the by-pass contactor comprises three parallel alternating-current contactors, and each alternating-current contactor is respectively in parallel connection with a triggering module; a voltage detection module, a controller, a driving circuit and a current detection module which are electrically connected are arranged on the soft-start main control board; and a display module and an input module are connected onto the controller. According to the soft starter with the built-in by-pass, as the by-pass is built-in, the size and the weight of the soft starter are reduced.
Description
Technical field
The utility model relates to electricity field, refers to especially a kind of soft starter with built in bypass.
Background technology
The external bypass contactor of existing soft starter as shown in Figure 1, during startup, by bypass contactor short circuit soft starter, can prevent that static torque is excessive.But use inconvenience, the supporting inconvenience of product, and supporting rear volume is large, and weight is large.
Utility model content
The utility model proposes a kind of soft starter with built in bypass, solved the supporting inconvenience of product and the large problem of supporting rear volume weight in prior art.
The technical solution of the utility model is achieved in that
With a soft starter for built in bypass, it comprises starter shell, is provided with bypass contactor and soft start master control borad in described shell; Described bypass contactor comprises three A.C. contactors in parallel, and each A.C. contactor is parallel with respectively again 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 undertaken after voltage detecting by described voltage detection module, enters in described controller, and controller shows Voltage-output to display module; Simultaneously described controller transmission enabled instruction to trigger module, makes motor operation through described drive circuit.When motor total head is moved, bypass contactor KM automatic pick.
Preferably, described trigger module is formed in parallel by two unidirectional thyristors, and the conducting direction of two unidirectional thyristors is contrary.
Preferably, described input module comprises keyboard or button.
Preferably, described display module is display screen.
The utility model, by bypass contactor is built-in, has reduced the volume after existing product is supporting.
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 external circuit connection diagram of bypass in prior art;
Fig. 2 is the circuit link block figure of the soft starter embodiment of the utility model band built in bypass;
Fig. 3 is the circuit connection diagram of the utility model 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 Figures 2 and 3, 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. 2 in described shell; Described bypass contactor comprises three A.C. contactors in parallel, i.e. illustrated KM, and each A.C. contactor is parallel with respectively again 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 voltage detection module, detects three-phase voltage and whether reaches set point.When the error range of voltage not set point Shang Xia 20% within while starting, soft starter will be protected.After in the voltage access controller that meets set point, controller shows Voltage-output to display module; With Time Controller send 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, bypass contactor KM adhesive, bypass contactor drops into and automatically by continuous service, and at this moment soft starter is still in running status but do not have electric current to pass through it, and electric current is by the complete bypass contactor of all flowing through.
In illustrated embodiment, described trigger module is formed in parallel by two unidirectional thyristors, and the conducting direction of two unidirectional thyristors is contrary.Described input module comprises keyboard or button, also can adopt the modes such as touch-screen.Described display module is display screen, is preferably LED display.
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.
