Abstract
The invention provides a 360 degree phasor diagram drawing template. The 360 degree phasor diagram drawing template comprises a transparent disk; the center of the disk is provided with a first through hole; a circle of angle scales are arranged on the disk to surround the center of the circle; a second through hole, a third through hole and a fourth through hole are formed at the positions corresponding to the 0 degree scale, the 120 degree scale and the 240 degree scale respectively; a circle of arc-shaped groove is formed along the scales; the arc-shaped groove penetrates the disk; a gap is reserved between the head portion and the tail portion of the arc-shaped groove; the arc-shaped groove comprises three sections; spaces are reserved at the positions corresponding to the 60 degree scale, the 180 degree scale and the 300 degree scale respectively; the edge of the disk comprises a circle of angle scales; the second through hole, the third through hole and the fourth through hole are formed in the periphery of the arc-shaped groove. According to the 360 degree phasor diagram drawing template, the arithmetic step is omitted during drawing and accordingly the judgment accuracy is improved; the length of three types of lines can be well controlled and accordingly the attractive and neat effect is achieved; the360 degree phasor diagram drawing template is suitable for the drawing of three-phase four-line and three-phase three-line vector diagrams.
Description
Technical field
The present invention relates to a kind of 360 degree of phasor diagram drawing templates, is the instrument that a kind of power domain draws vectogram.
Background technology
When the mistake of false wiring of electric energy meter electricity calculates, need to carry out the judgement of picture vector diagram analysis according to surveyed data, when drawing angle, general quantity hornwork only has 180 ° of degree, and survey data 0 ° ~ 360 ° degree within, as U1I2=254 ° of degree, commonly use have three kinds of methods:
1, on 180 ° of degree, (254 °-180 °)=74 ° of degree are added;
2, oppositely drafting is measured, (360 °-254 °)=106 ° of degree;
3, on the phase voltage line of previous 240 ° of degree, (254 °-240 °)=14 ° of degree are added.
Don't work which kind of mode above, between always have the process of a mental arithmetic, easily make mistakes; And it is slow to draw, and loses time; Line length can only control 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, provide a kind of 360 degree of phasor diagram drawing templates, it is simple and easy to use, raises the efficiency.
According to technical scheme provided by the invention, 360 degree of described phasor diagram drawing templates comprise a transparent disc, the circle centre position of disk is provided with the first through hole, disk there is one week angle index around the center of circle, to scale 0 degree, the position of 120 degree, 240 degree being 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, reserves interval between deep-slotted chip breaker head and the tail.
Concrete, described deep-slotted chip breaker comprises three sections, reserves interval respectively at corresponding scale 60 degree, 180 degree, 300 degree places.
Concrete, within one week, also there is angle index at the edge of described disk.Described second through hole, third through-hole and fourth hole are in the periphery of deep-slotted chip breaker.
Advantage of the present invention is:
Eliminate mental step when 1, drawing, improve judging nicety rate;
2, the length of lines is same, carefully and neatly attractive in appearance;
3, draw than very fast, save time.
Accompanying drawing explanation
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, disk 1 there is one week angle index around the center of circle, to scale 0 degree, the position of 120 degree, 240 degree being respectively equipped with the second through hole 3, third through-hole 4 and fourth hole 5, have a circle deep-slotted chip breaker 6 along described scale, deep-slotted chip breaker 6 penetrates described disk 1, reserves interval between deep-slotted chip breaker 6 head and the tail.Deep-slotted chip breaker 6 shown in Fig. 1 comprises three sections, reserves interval respectively at corresponding scale 60 degree, 180 degree, 300 degree places.Within one week, also there is angle index at the edge of described disk 1.Described second through hole 3, third through-hole 4 and fourth hole 5 are in the periphery of deep-slotted chip breaker 6.
Preparation method of the present invention is:
1, make a disk with the transparent organic glass that 1 ~ 1.5mm is thick, and print or engrave scale, angular values;
2, bore 4 apertures above, one is centre bore (central point of vectogram), and between its excess-three aperture, 120 degree, each interval (is phase voltage U respectively
u, U
v, U
wend points);
3, mill out the groove of three arcs in addition again, be inserted in the inside for nib and draw phase current (see I in Fig. 2
w,-I
u) end points.
According to data from the direct measuring angle of starting point, add chain-dotted line.Outer scale is used for the drafting of phase three-wire three vectogram (see U in Fig. 2
uV, U
wV).
Can be seen by Fig. 2, use this template to draw the length that can control three class lines preferably, carefully and neatly attractive in appearance; This template can be applicable to the drafting of three-phase and four-line and phase three-wire three vectogram.
