MR479E Set of Training and Laboratory Equipment Teaching Equipment Classroom Training Set Smart Grid Training Equipment I.Product Overview 1.1 Overview Before the experiment, training can be provided to familiarize students with the causes of various electric shock accidents, thereby preventing the occurrence of electric shock accidents. Through learning, students will understand how accidents occur and pay attention to the occurrence of electrical accidents, thereby enhancing their ability to prevent accidents and solve electrical accidents. Students can learn a variety of security protection modes from the trainer. 1.2 Features (1) The training workbench uses aluminum alloy columns, test measures, and an integrated training power box. It is easy to use and not easily damaged. (2) Modular structure: There are many modules, which can realize many training projects. Please refer to the equipment list listed later. (3) It has a good safety protection system. All electrical terminals use safety plug terminals. The whole machine can be grounded. If leakage occurs, students can immediately cut off the power to protect themselves.
