Problems solved by technology

In actual use, the prior art has the following deficiencies: 1. The color coating will fade and change color under the sun and rain, which is easy to cause misjudgment; and the regular replacement of the phase signboard will increase manpower and material resources
2. For color-blind employees, it is difficult to distinguish the color phase signs
3. When the light is insufficient or backlit, it is difficult to distinguish the color phase signs
4. The corresponding relationship between color and phase is easy to remember and confuse

specific Embodiment approach 1

[0013] Specific implementation mode 1 such as figure 1 As shown, the frame of the phase sign board or the color paint frame distinguishes the phases with geometric figures, including regular triangles to mark phase A 1, squares to mark phase B 2, and circles to mark phase C 3.

[0014] The technical feature of the present invention is that it is marked by the geometric figure associated with the shape of the phase sequence letters, so that when people see a triangle, they are easy to think of phase A, when they see a square, they are easy to think of phase B, and when they see a circle, they are easy to think of phase C . On this basis, it is also the protection scope of the specific embodiment of the present invention to add phase sequence letters or text marks, or paint color marks.

specific Embodiment approach 2

[0015] Specific implementation mode 2 such as figure 2 As shown, an inner frame identification phase signboard 4, according to the arrangement orientation of the ABC three phases, correspondingly hollowed out triangles, squares and circles on a signboard to represent the ABC three phases respectively. Embodiment 2 is suitable for hanging a sign board at the bottom of the pole tower to identify the phase sequence of the wires hung on the cross arm.

specific Embodiment approach 3

[0016] Specific embodiment 3 such as image 3 As shown, a phase identification plate with inner and outer frames, including phase A identification plate 5, phase B identification plate 6 and phase C identification plate 7, is suitable for larger three-phase independent identification plates, the internal hollow reduces the wind resistance area, and can be installed On a tower over 50 meters high.

Abstract

The invention provides a shape phase sign board. Phases of a frame or a color paint frame of the phase sign board are distinguished through geometric figures, wherein the phase A is a right triangle, the phase B is a square, and the phase C is a circle. The phases can still be distinguished after color paint fades and changes color. Manpower and materials used for replacing the phase sign board are reduced. When it is dark or backlighting happens and even for staff with color blindness, the phases can be easily distinguished. The association degree of the sign board and the phases is high, and corresponding relations are easy to remember and distinguish.

Description

technical field [0001] The invention relates to electric power accessories, in particular to a shape phase signboard. Background technique [0002] On power transmission and transformation equipment, phase signs are usually used to mark the phases, which are generally stipulated to be installed on the cross-arm of the iron tower. Misjudgment of the phase may lead to wrong wiring, and a short-circuit accident occurs during power transmission, with serious consequences. The existing technology is to use color to distinguish or combine letters to distinguish ABC three phases, and the frame shape or color frame shape of the phase sign board is the same among the three phases. In actual use, the prior art has the following deficiencies: 1. The color coating will fade and change color under the sun and rain, which easily leads to misjudgment; and the regular replacement of the phase signboard will increase manpower and material resources. 2. For color-blind employees, it is diff...
