Electrical Operation Platform<\/h1>\n

Functional Requirements:<\/h2>\n
    \n
  1. The platform can realize comprehensive practical training such as AC\/DC electric drive, motor control circuit, relay contact control, RLC programmable control, lighting power distribution simulation operation, installation and commissioning, etc.<\/li>\n
  2. It adopts a pendant structure, allowing arbitrary modification of experimental components to increase experimental content, facilitating secondary development and functional expansion.<\/li>\n
  3. The platform shall be equipped with voltage – type leakage protectors and current – type leakage protectors to ensure operational safety. Each power output shall have monitoring, short – circuit protection and other functions, and each measuring instrument shall have protection functions.<\/li>\n
  4. The motor is installed in the experimental platform, and a transparent organic glass isolation panel is used to clearly observe the operation of the motor.<\/li>\n
  5. The platform power supply has a fault locking function. When handling faults, it prevents the leakage protector from closing, thus avoiding the risk of electric shock.<\/li>\n
  6. The platform removes wireless modules such as Bluetooth connections and can operate independently offline.<\/li>\n
  7. The platform shall have a fire – resistant, waterproof, wear – resistant, spacious and comfortable workbench surface, with universal wheels installed at the bottom for easy movement.<\/li>\n
  8. According to the characteristics of different operation projects, it is equipped with high – reliability sheathed structure pistol plug connecting wires suitable for strong and weak electricity operation projects (if any), and elastic beryllium – copper exposed structure connecting wires suitable for adaptive digital – analog signal operation projects (if any). The three types of wires can only be connected to the corresponding matching sockets to improve the safety and rationality of the experiment.<\/li>\n<\/ol>\n

    Technical Parameters:<\/h2>\n
