Abstract
The invention provides a kind of 360 degree phasor diagram drawing templates, it comprises a transparent disc, the circle centre position of disk is provided with the first through hole, on disk, there is one week angle index around the center of circle, to should scale 0 spend, the positions of 120 degree, 240 degree are respectively equipped with the second through hole, third through-hole and fourth hole, have a circle deep-slotted chip breaker along described scale, deep-slotted chip breaker penetrates described disk, between deep-slotted chip breaker head and the tail, reserves interval. Described deep-slotted chip breaker comprises three sections, spends, 180 degree, 300 degree places reserve respectively interval at corresponding scale 60. Edge at described disk also has angle index for one week. Described the second through hole, third through-hole and fourth hole are in the periphery of deep-slotted chip breaker. Advantage of the present invention is: draw and removed mental arithmetic step by this template, improve judging nicety rate; Can control preferably the length of three class lines, attractive in appearance carefully and neatly done; This template can be applicable to the drafting of three-phase and four-line and phase three-wire three vectogram.
Description
Technical field
The present invention relates to a kind of 360 degree phasor diagram drawing templates, is the instrument that a kind of power domain is drawn vectogram.
Background technology
When the mistake of false wiring of electric energy meter electric weight is calculated, need to carry out the judgement of picture vector diagram analysis according to surveyed data,Drawing when angle, general quantity hornwork only has 180 ° of degree, and the data of surveying within 0 °～360 ° degree, as U1I2=254 ° of degree,Conventional have three kinds of methods:
1, on 180 ° of degree, add (254 °-180 °)=74 ° of degree;
2, oppositely measure and draw, (360 °-254 °)=106 ° of degree;
3, on the phase voltage line of 240 ° of previous degree, add (254 °-240 °)=14 ° of degree.
Above which kind of mode that don't work, between always have the process of a mental arithmetic, easily make mistakes; And it is slow to draw,Lose time; Lines length can only be controlled with sensation, often can be different in size.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of 360 degree phasor diagram drawing templates are provided, itsBe simple and easy to use, raise the efficiency.
According to technical scheme provided by the invention, 360 described degree phasor diagram drawing templates comprise a transparent disc, circleThe circle centre position of dish is provided with the first through hole, has one week angle index on disk around the center of circle, to should scale 0 spend, 120 degree, 240The position of degree is respectively equipped with the second through hole, third through-hole and fourth hole, has a circle deep-slotted chip breaker along described scale, and deep-slotted chip breaker is wornSaturating described disk, reserves interval between deep-slotted chip breaker head and the tail.
Concrete, described deep-slotted chip breaker comprises three sections, spends, 180 degree, 300 degree places reserve respectively interval at corresponding scale 60.
Concrete, within one week, also there is angle index at the edge of described disk. Described the second through hole, third through-hole and the 4thThrough hole is in the periphery of deep-slotted chip breaker.
Advantage of the present invention is:
1, while drawing, remove mental arithmetic step, improved judging nicety rate;
2, the length of lines is same, attractive in appearance carefully and neatly done;
3, draw than very fast, save time.
Brief description of the drawings
Fig. 1 is die shape figure of the present invention.
Fig. 2 is the phasor diagram example of drawing with the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, the present invention includes a transparent disc 1, the circle centre position of disk 1 is provided with the first through hole 2, on disk 1Have one week angle index around the center of circle, to should scale 0 spend, the positions of 120 degree, 240 degree are respectively equipped with the second through hole 3, theThree through holes 4 and fourth hole 5, have a circle deep-slotted chip breaker 6 along described scale, and deep-slotted chip breaker 6 penetrates described disk 1, deep-slotted chip breaker 6 head and the tailBetween reserve interval. Deep-slotted chip breaker 6 shown in Fig. 1 comprises three sections, spend at corresponding scale 60,180 degree, between 300 degree places reserve respectivelyEvery. Edge at described disk 1 also has angle index for one week. Described the second through hole 3, third through-hole 4 and fourth hole 5 are at arcThe periphery of shape groove 6.
Preparation method of the present invention is:
1, make a disk with the thick transparent organic glass of 1～1.5mm, and printing or engrave scale, angle numerical value;
2, bore 4 apertures in the above, one is centre bore (central point of vectogram), each interval between its excess-three aperture120 degree (are respectively phase voltage UU，UV，UWEnd points);
3, mill out again in addition the groove of three arcs, be inserted in the inside drafting phase current for nib and (see Fig. 2 IW，-IU) endPoint.
From the direct measuring angle of starting point, add chain-dotted line according to data. Outer scale (is shown in for the drafting of phase three-wire three vectogramU in Fig. 2UV，UWV）。
Can be seen by Fig. 2, draw and can control preferably the length of three class lines by this template, attractive in appearance carefully and neatly done; ThisTemplate can be applicable to the drafting of three-phase and four-line and phase three-wire three vectogram.
