Abstract

The invention discloses a phase angle drawing device for power, and the phase angle drawing device is used for realizing efficient and precise drawing for a phase angle. From the center of the top of a base, a supporting rod is upwards extended; a movable rod is arranged on the supporting rod; a jack screw is arranged between the supporting rod and the movable rod; the outer wall of the movable rod is provided with a lamp holder support; a lamp holder is mounted in the lamp holder support in a hinged mode; a lamp tube is arranged in an inner cavity of the lamp holder; a tapered seam is formed in the lamp holder; a switch is arranged on the base; the switch, the lamp holder and a storage battery on the base form an illuminating current loop; a positioning assembly is arranged between an inner plate and the base; the side edge of the inner plate is provided with inner scale marks; the outer plate can be mounted on the inner plate in a relatively rotary mode; and the outer plate is provided with outer scale marks. The device is convenient and simple in use, and capable of efficiently realizing phase angle drawing.

Description

technical field [0001] The invention relates to the technical field of electric power tools, in particular to a phase angle drawing device for electric power. Background technique [0002] In electrical design, plotting phase angles is a common task. At present, when drawing the phase angle, it is generally drawn by a ruler or a triangle ruler. In this way, the drawing accuracy and efficiency are relatively low. Therefore, there is an urgent need for a phase angle drawing device that is easy to use and has high drawing precision, so as to facilitate the drawing of the phase angle. Contents of the invention [0003] The purpose of the present invention is to provide a phase angle drawing device for electric power, which is used to realize efficient and accurate drawing of the phase angle. [0004] The technical solution adopted by the present invention to solve the technical problem is: a phase angle drawing device for electric power, which is characterized in that it inc...
