The applicable scope covers power industry training institutions, vocational colleges and in-house training of power enterprises, and can be used for skill training, teaching, assessment competitions, etc. It can effectively improve the professional skills of students and employees, and meet the training needs of high-voltage electricians and operation and maintenance personnel in different scenarios.

[0010] Preferably, the main equipment module in the main component unit includes a lift, which includes a motor (using a high-efficiency and energy-saving three-phase asynchronous motor, with characteristics such as large starting torque, stable operation and low noise, providing power for the lift), a fall arrester, a guide rail and a safety lock.

[0011] Preferably, the main equipment module further includes a high-voltage drop-out fuse and an arc simulator.

[0018] Step 2: And perform the fuse replacement operation. After the training stand simulates the fuse melting fault of the high-voltage drop-out fuse, perform the fuse replacement operation. First, the trainee uses a link stick and removes the fuse tube in the open state according to the correct operation method. During the operation, pay attention to the angle and depth of inserting the link stick into the fuse tube hook to ensure the smooth removal of the fuse tube. At the same time, avoid touching other live parts. After removing the fuse tube, check the melting situation of the fuse, and then replace it with a new fuse. When replacing, ensure that the fuse specification is the same as the original fuse, install it firmly, and have good contact. Reinstall the fuse tube with the replaced fuse back into the high-voltage drop-out fuse.

If it is normal, the equipment resumes operation.

[0019] Step 3: Drop-out fuse replacement operation. Before the operation, ensure that the platform has been lowered to a suitable height and the equipment has been powered off. The trainee uses appropriate tools to sequentially remove the connection bolts of the old drop-out fuse, untie the lead wires, etc. During the removal process, pay attention to recording the installation positions and connection methods of each component to avoid errors when installing the new fuse. When installing the new drop-out fuse, first correctly install the fuse body on the bracket, and then connect the lead wires according to the standard process to ensure firm connection and good contact. Finally, tighten the bolts to make the fuse installed firmly. After installation, check the installation of each component again. After confirming that there is no error, power on the equipment and observe the equipment status on the display panel.

Before connecting the system to the power supply, check the integrity of the system. It is strictly prohibited for anyone to modify the structure of the system), first electric shock danger (the electrical components used in the device are high-power electrical devices. When the device is running, some parts of the system will be connected to dangerous high-voltage power supplies. Therefore, the electrical installation and disassembly in the device can only be completed by trained and qualified personnel. Incorrect installation may damage the system, even cause accidents or material losses. Therefore, it is necessary to abide by the guidance in this manual and local and national safety standards);

[0030] Second electric shock hazard (Do not turn on the power when the system is not grounded. The grounding conductor of this experimental device must be different from the wiring conductors used in other devices to achieve good anti-interference performance. A corresponding grounding bar must be used to fix the grounding conductor (PE), and mechanical support bolts shall not be used as the grounding conductor), third electric shock hazard (The system must be grounded in accordance with national electrical standards), fourth electric shock hazard (Before turning on the device power supply, all mechanical and electrical protection devices must be set up), fifth electric shock hazard (It is necessary to ensure that the installation location of the system has good heat dissipation performance and that the heat dissipation efficiency will not decrease due to long-term use. Excessive temperature will cause the performance of the system to deviate from the rated value range and shorten the service life of the system), fire and short circuit hazards (When using some instruments connected to powered devices, appropriate measures must be taken to avoid fire or short circuit hazards. For example, when using aviation plugs for connection, make sure the connection is firm and accurate, and there is no loose connection. The measurement of voltage signals must be carried out using an instrument with an appropriate internal resistance (at least 10 kΩ / V)), fire and explosion hazards (Installing the system in a hazardous area with flammable liquids, gases or powders may cause fire or explosion accidents. An appropriate distance must be maintained between the installation location of the system and these hazardous areas and the installation location of motors suitable for use under such conditions), second damage hazard (It is strictly prohibited to connect the device to a power supply with a voltage exceeding the allowable voltage range. When the voltage is too high, it may damage the internal components of the system. It is strictly prohibited to apply voltage to the terminals of the system), personal injury hazard (In accordance with the provisions of the EEC standard, after completing the compliance inspection of the device with the safety requirements in the 2006 / 42 / EC and LVD 2006 / 95 / EC standards, the system and its accessories must be operated by qualified personnel) and third damage hazard (When the system gives an alarm status indication signal, the cause of the alarm must be found out and eliminated in a timely manner before it can continue to return to the normal operating state).

The high-voltage drop-out fuse includes insulators (using high-strength and high-insulation ceramic insulators or composite insulators to support the high-voltage drop-out fuse and ensure its insulation performance, preventing current leakage), a fuse tube (internally equipped with a fuse wire. When the circuit is overloaded or short-circuited, the fuse wire melts to cut off the circuit and protect the equipment safety. The fuse tube is made of materials with high temperature resistance and good insulation performance and has good arc extinguishing performance), and contacts (divided into moving contacts and static contacts for realizing the connection and disconnection of the circuit. The contacts are made of high-quality conductive materials with good conductivity and wear resistance to ensure reliable contact).
