Further, described operation panel is also provided with reset button, described reset button is connected with circuit of testing the phase sequence, for recovering the original state of circuit of testing the phase sequence.
The beneficial effects of the utility model are: power circuit and operation panel are arranged on base by the utility model; And adopting digital integrated circuit, working stability is reliable; Circuit is simple, compact, can be fixedly installed in a certain concrete circuit to be used as to monitor, and can apply with oneself again as a testing tool.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
The portable phase order of 3-phase AC detector arrangement figure that Fig. 1 provides for the utility model embodiment;
The circuit of testing the phase sequence circuit diagram that Fig. 2 provides for the utility model embodiment.
In figure, base 1; Operation panel 2; Fixed station 3; Circuit board 4; Display circuit 5; Power circuit control knob 6; Phase line connecting interface 7; Reset button 8.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only in order to the utility model is described, instead of in order to limit protection domain of the present utility model.
As shown in the figure, the portable phase order of 3-phase AC detecting device of the one that the utility model provides, comprises base 1, power circuit and operation panel 2; Described base is provided with the fixed station 3 projected upwards; Described fixed station is arranged circuit board 4; Described circuit board is provided with power circuit and the circuit of testing the phase sequence be connected with power circuit respectively and display circuit 5; Described circuit of testing the phase sequence is connected with display circuit; Described operation panel and base engagement form the casing being used for containment circuit board and power circuit.
Described operation panel is provided with power circuit control knob 6, phase line connecting interface 7; Described phase line connecting interface is connected with the input port of circuit of testing the phase sequence on circuit board.
Described display circuit is arranged on operation panel and is connected with circuit of testing the phase sequence, for showing the testing result of circuit of testing the phase sequence.
Described operation panel is also provided with reset button 8, and described reset button is connected with circuit of testing the phase sequence, for recovering the original state of circuit of testing the phase sequence.
Circuit of testing the phase sequence specific works principle in the phase order of 3-phase AC detecting device that the present embodiment provides is as follows:
Three-phase alternating current accesses A, B, C tri-end respectively after step-down, rectification, and A, B two ends are respectively through 2 the clock pulse signal ends delivering to IC integrated circuit after resistor R1, R2 and voltage stabilizing diode VS1, VS2 amplitude limit, shaping.If phase sequence correct (i.e. A, B, C tri-phase sequence occur positive pulse), then 1 pin of IC integrated circuit and 13 pin all export high level, and make VT1, VT2 conducting, relay K coil obtains electric, and the moving together contact of K is closed, and consumer is started working.Now, C end is by the reset terminal output reset signal of resistor R3 and stabilivolt VS3 to IC integrated circuit, 1 pin and 13 pin output low levels, owing to capacitor C2 starting electric discharge, making triode VT1, VT2 continue conducting maintenance relay continues electric, load normally works, and completes the change of three-phase alternating current one-period.If phase sequence mistake, then make 13 pin keep low level, triode VT1, VT2 end, the coil losing electricity of relay K, and the moving together contact of K disconnects, and consumer quits work.Triode VT1, VT2 select S9013 type silicon NPN transistor; IC selects CD4013 type double D trigger integrated circuit; K selects JRX-13F type 12V DC relay.
The display circuit of the present embodiment can adopt light-emitting component and light emitting diode to show testing result.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described the utility model by referring to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, various change can be made to it in the form and details, and not depart from the spirit and scope that the utility model limits.
