Problems solved by technology

[0002] Existing power metering teaching devices usually use a cabinet or box structure for on-site simulation teaching with reference to the actual power metering box. Although this built-in structure can realistically restore the scene and make students feel like they are there, there are the following problems that cause teaching Problems of low efficiency and quality:
[0003] (1) The space in the cabinet or box is narrow, the electrical components inside are installed compactly, the primary and secondary circuit connections are complicated and chaotic, and students have a learning psychology of being esoteric and fearful of measurement technology;
[0004] (2) The cabinet or box structure usually only has a front opening as an observation surface, and the actual display range and angle inside it are relatively limited, so it must be combined with the wiring diagram for students to understand;
[0005] (3) It is only suitable for close observation, and the process of students watching may lead to disorder in the classroom and poor teaching continuity;

Abstract

The invention discloses an electric power measurement teaching device, which comprises an electric power measurement device, and further comprises a display panel which is vertically arranged, whereina mounting plate is arranged at the bottom of each electrical element of the electric power measurement device, and the electrical elements are fixed to a same display side of the display panel by virtue of the mounting plates; mounting holes are distributed in the display panel; pin columns are arranged at the upper sides of the mounting plates, and notches, in which the mounting holes can be clamped, are arranged in the pin columns; magnets are embedded in the mounting plates; and the display panel is a metal plate or a magnetic insulating plate. According to the electric power measurementteaching device provided by the invention, teaching can be demonstrated through plane development of the electric power measurement device, and the electric power measurement teaching device is well organized in circuit layout, convenient for students in understanding and practicing and capable of overcoming student learning psychology of feeling deep and afraid of measurement device technology; meanwhile, sight lines of students can be prevented from getting sheltered, and coherent and ordered classroom teaching can be guaranteed, so that teaching efficiency and quality are effectively improved; and in addition, in accordance with structures of different measurement devices, arrangement positions and wiring modes of electrical elements on the measurement devices are variable, and the measurement teaching device is simplified.
