I. Overview

The electrical installation and maintenance training and assessment device is a universal training platform developed in accordance with the training and appraisal requirements for maintenance electricians and electrical installers in factory electrical installation, indoor electrical installation, etc. It is very suitable for various vocational colleges and technical schools as a public platform for maintenance electricians, electrical installers, and other majors with electrical installation requirements. It is composed of steel mesh panels and special steel profiles, equipped with self-locking casters for easy movement and use. The surface of the device is spray-painted with a stable color. The device is equipped with a dedicated power supply station. The design height of the device allows convenient operation when a person stands on a one-step stepladder, which is safe and enables users to experience the construction site environment. The horizontal and vertical widths are appropriate, which can simulate the steering arrangement of on-site lines. The mesh panel can be easily removed. To facilitate the construction of concealed works, the industrial aluminum profile frame imitates building partitions with pipe 穿 holes, and cable ties are used to fix the conduit. When passing through the mesh panel, wall bushings can be used to lead wires into the surface-mounted junction box. The supporting PVC pipe bender can easily bend the PVC pipe into 90 degrees. Electrical installation can be carried out, such as bridge installation, PVC pipe installation, chandeliers, incandescent lamp holders, fluorescent lamps, switches, sockets, distribution boxes, control boxes, etc. The device also includes AC asynchronous motors, DC motors, stepper motors, temperature controllers, thermocouples, PLC, inverter touch screens, and other control and controlled objects. Each operation group of the system is equipped with a mobile tool cart and a component cabinet, which is convenient for the storage and installation of components. It fundamentally solves the problems of inconvenient use and narrow training scope in school installation training conducted on ordinary walls. It has the characteristics of flexible and convenient assembly. According to the actual teaching conditions of the school, it can be formed into 2-person groups, single-sided, and multi-angle combinations based on 2 basic combination units of 0.8 meters, supplemented by combination units of 0.2 meters and 0.4 meters to form different length combinations to meet different teaching venues. It can provide training and assessment for various post groups with electrical installation requirements such as hydropower installers.
