Experiment display device for electrical teaching

Abstract

The invention discloses an experiment display device for electrical teaching. The device comprises two to three electrical cabinets, connecting plates are fixed between the two to three electrical cabinets through bolts; convection holes are formed between the connecting plates; a base is fixed to the outer wall of the bottom of each electrical cabinet through bolts. An instrument cabinet head isintegrally connected to the outer wall of the top of each electrical cabinet, side fixing frames are welded to the inner walls of the two sides of each electrical cabinet, inserting strips are slidably connected to the inner walls of the side fixing frames in a clamped mode, a heat dissipation back plate is fixed to the outer wall of one side of each electrical cabinet through bolts, and buckles are welded to the inner walls of the heat dissipation back plates. According to the invention, transparency of components in different electrical cabinets is realized through the disc type adjusting structure; components are connected to form an open-end circuit, functional detection on the open-end circuit is achieved through the instrument cabinet head and the detection structure, it is guaranteed that all the components and connection modes are visually displayed in the whole electrical teaching process, learners can better understand the components and connection modes, and the teaching effect is better.

Description

technical field [0001] The invention relates to the technical field of electrical teaching, in particular to an experimental display device for electrical teaching. Background technique [0002] Electrical engineering is one of the core disciplines in the field of modern science and technology, and it is an indispensable key discipline in today's high-tech field. In a sense, the degree of development of electrical engineering represents the level of scientific and technological progress of the country. Because of this, the education and scientific research of electrical engineering has always occupied a very important position in universities in developed countries. During the learning process of electrical engineering, many circuits and electrical tests are demonstrated on site, requiring a lot of equipment to connect and explain the principles. Some circuits or connection principles taught on site will have many unintuitive places, which will affect learning. [0003] Th...

Problems solved by technology

During the learning process of electrical engineering, many circuits and electrical tests are demonstrated on site, requiring a lot of equipment to connect and explain the principles. Some circuits or connection principles taught on site will have many unintuitive places, which will affect learning

[0003] The existing electrical teaching experiment display devices have the following disadvantages: the existing electrical teaching display devices on the market are often too single in structure, the scope of teaching application is not wide, and they are often large in size and inconvenient to display
