Electric power phasor diagram drawing ruler

Abstract

The invention belongs to the technical field of electric power tools, and particularly relates to an electric power phasor diagram drawing ruler which is composed of a first ruler body (1) and a second ruler body (2), the outer edge of the first ruler body is round, the outer edge of the second ruler body is rectangular, and the first ruler body (1) and the second ruler body (2) are both made of transparent plastic. The phasor diagram ruler is characterized in that the first ruler body (1) and the second ruler body (2) are both of special shapes and structures. The phasor diagram ruler solves the problems that an electric power worker cannot draw a phasor diagram conveniently and quickly, and no tool can be directly used in the prior art. The drawing device has the main beneficial technical effects that the structure is compact, the design is reasonable, the operation is simple, the cost is low, the labor intensity of personnel is greatly reduced, and the drawing efficiency is improved; the practicability and the applicability are high; the carrying is convenient; the service life is long; the operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of power tools, in particular to a drawing ruler for electric phasor diagrams. Background technique [0002] In the prior art, when drawing the phasor diagram and the wiring diagram of the wiring inspection record sheet of the electric energy metering device, a computer or manual drawing is used. Although the computer has many advantages, it is not very convenient to carry, and it is not convenient to use it anytime and anywhere. Printing; when drawing by hand, two methods are usually used, one is to use a semicircle protractor to draw, and the other is to use a circular multifunctional ruler. Among these two drawing tools, the former needs to draw points outside the semicircle to continue drawing when drawing angles , the overall appearance of the drawings is affected and the drawing efficiency is slow.

Problems solved by technology

[0002] In the prior art, when drawing the phasor diagram and the wiring diagram of the wiring inspection record sheet of the electric energy metering device, a computer or manual drawing is used. Although the computer has many advantages, it is not very convenient to carry, and it is not convenient to use it anytime and anywhere. Printing; when drawing by hand, two methods are usually used, one is to use a semicircle protractor to draw, and the other is to use a circular multifunctional ruler. Among these two drawing tools, the former needs to draw points outside the semicircle to continue drawing when drawing angles , the overall appearance of the drawings is affected and the drawing efficiency is slow. Although the latter can rotate the internal structure to achieve fast drawing speed, but for the special drawing of measurement vector diagrams, the angle and length measurement on the ruler is powerless. Although there are electricians on the market ruler, but it is not suitable for the rapid drawing of power phasor diagrams. Therefore, it is an urgent problem to develop a method that can deal with wiring phasor diagrams and actual wiring diagrams.
