Multifunctional safe type electricity experiment table

Abstract

The invention provides a multifunctional safe type electricity experiment table which comprises a main body, a rear cover plate, a roller shutter and a printed circuit board, wherein an electricity operation bench is mounted above the main body; an inspection window is arranged on the rear cover plate; a camera is arranged on the roller shutter; the printed circuit board is electrically connected to the electricity operation bench through a circuit; and a current sensor, a voltage sensor and a relay are mounted in the circuit. Compared with the prior art, the multifunctional safe type electricity experiment table has the following beneficial effects: a standby power supply can replace an external power supply to supply power to the electricity operation bench; by the additional arrangement of the inspection window, a teacher can conveniently explain the structure of the electricity operation bench, and the electricity operation bench is convenient to repair and check when having a fault; the electricity operation bench can be protected; and by the arrangement of the camera and a teacher control terminal, when a student operates the electricity operation bench, the teacher can learn about the operations of multiple students through the teacher control terminal, so as to direct the students conveniently.

Description

technical field [0001] The invention is a multifunctional and safe electrical experiment table, which belongs to the field of electrical equipment for college students. Background technique [0002] The electrical experiment is an important part of the physical experiment. In the electrical experiment of college students, the general electrical experiment is operated on the electrical experiment table. We know that the physical electrical experiment table is equipped with a power supply system with an electric meter. It is mainly composed of an operating table, a table top and table legs. [0003] The electrical experiment table in the prior art generally has the following problems. One: generally all are powered by an external power supply. Teaching has caused a lot of trouble; two: sometimes in teaching, the teacher will explain the operating table in the electrical experiment table, and the general explanation includes the function, usage and structure of the operating t...

AI Technical Summary

Problems solved by technology

[0003] The electrical experiment table in the prior art generally has the following problems. One: generally all are powered by an external power supply. Teaching has caused a lot of trouble; two: sometimes in teaching, the teacher will explain the operating table in the electrical experiment table, and the general explanation includes the function, usage and structure of the operating table, but the existing electrical experimental table It is impossible for students to see the internal structure, and sometimes, when there is a problem inside the console, because it is impossible to determine which part has the problem, the entire rear cover needs to be removed for maintenance, which is very troublesome; 3: General electricity The operating table of the experimental table is exposed to the air, and if it is exposed to the air for a long time, it is not only not conducive to preservation, but also easy to damage; 4: When the teacher teaches the students, he needs to watch whether the operation is correct, but the general operation method is It is impossible for a teacher to watch a student operate an electrical experiment table one by one, which will affect the quality of teaching
