[0002] As we all know, electricians must possess necessary electrical professional knowledge and electrical safety technology, master necessary operation skills, and obtain an electrician vocational qualification certificate before they can take up their posts. Traditional low-voltage electrician operation training and examinations adopt a pure physical and chemical examination method, only examining electrical-related knowledge, and cannot examine the actual hands-on operation technology of candidates. The examination requirements for the installation, commissioning, operation, and maintenance of low-voltage electrical equipment cannot be achieved, and practitioners cannot obtain independent operation capabilities.

[0003] The existing comprehensive experimental platform for high-voltage electrician practical operation examinations with the patent number CN113129714A specifically discloses a comprehensive experimental platform for high-voltage electrician practical operation examinations, which includes an experimental platform component. The experimental platform component consists of an isolating switch, several utility poles, an equipment cabinet, a user switch box, and a transformer. The isolating switch is electrically connected to the power connection end of the equipment cabinet to the right. The output end of the equipment cabinet is equipped with a drop-out fuse switch. The bottom wire of the drop-out fuse switch is connected to the primary side of the transformer. The secondary side of the transformer is wire-connected to the internal switch input end of the user switch box. The entire simulation system of the present invention uses all safety voltages, and the examination process is safe and reliable. All equipment is modified from real equipment and made through technological processes, with vivid images, closer to actual operations, and a more standardized examination process. It effectively solves the problem that existing training teachers cannot conduct detailed physical operation training, teaching can only stay at the theoretical level, and students are difficult to master the entire operation process, increasing the difficulty of training.

[0027] Embodiment 1:

[0028] Please refer to the attached Figure 1-2 , in the specific implementation process: a comprehensive training device for the safety operation technology of an indoor simulated 10kV overhead distribution line and a pole-mounted transformer, including: a safety appliance cabinet 1, an assessment component 2, a base 3, and an auxiliary structure; the auxiliary structure is installed on the safety appliance cabinet 1, the safety appliance cabinet 1 is installed on the base 3, and the assessment component 2 is installed on the base 3;

[0029] The auxiliary structure includes: a ventilation component, a lighting component, and a detection component;

[0030] The ventilation component is installed on the safety appliance cabinet 1, the lighting component is installed on the safety appliance cabinet 1, and the detection component is installed on the safety appliance cabinet 1;

[0031] It should be noted that: The assessment component is an existing technology: The assessment component consists of: 33 sets of four-wheel enlarged and weighted bases (reference dimensions 1000*2000*60), with a weight of 240*1000*8 added to the base 3, which is stable and safe. One set is equipped with 3 columns (numbered 1# rod, 2# rod, 3# rod), with heights of 1200, 1200, and 3000. The other two sets are respectively equipped with 2 columns (4# rod, 5# rod, 6# rod, 7# rod), with heights of 3000, 3000. Both the base 3 and the columns are beautifully spray-painted. The insulator binding workstations are set on the 1# rod and 2# rod, and the butterfly porcelain insulators and pin porcelain insulators are respectively fixed. A cross arm is set on the 3# rod to install a high-voltage disconnecting switch, and the wiring is connected to the 2# rod and 4# rod. The hanging protection wire workstations are set at the positions of the 4# rod and 5# rod. Hanging rings are set and high-altitude anti-falling devices are installed. A tool hanging and placing rack is equipped and a set of high-voltage discharge rods, a set of high-voltage voltage detectors, 1 insulating operating rod, a simulated live body, grounding wires, 1 set of 2500V insulation resistance meters, a group of test wires, and 2 short connection wires are equipped. 1 set of climbing and grounding depth simulation device is equipped. The on-pole transformer workstations are set on the 6# rod and 7# rod, and the cable extends from the 5# rod through the 6# rod to the 7# rod. 3-level cross arms are set between the 6# rod and 7# rod, which are respectively insulators, drop-out fuses, and lightning arresters. The cable enters the high-voltage side of the transformer, and the low-voltage side cable enters the low-voltage cabinet. The branch cable from the low-voltage cabinet is simulated to enter the ground and is beautifully fixed at the bottom of the 6# rod. A simulated grounding device is set at the bottom of the 7# rod, serving as the four-point grounding introduction point for the on-pole transformer (transformer neutral point grounding, transformer shell grounding, power distribution cabinet shell grounding, lightning arrester grounding). All cable wiring and accessories are connected according to the actual outdoor connection. All the electrical components involved achieve safe power-on operation, with the lights on and the meters moving. 1 set of physical cable insulation resistance measurement operation table is equipped. The reference dimensions of the operation table are 1500*1200*600, and the cable is introduced from the side of the operation table and beautifully fixed; composed, so that this comprehensive device of the assessment equipment needs to meet the following six assessment items: power on and off operation of the 10kV on-pole transformer, hanging protection grounding wires on the 10kV line, insulation test of the 10kV power transformer, adjustment of the tap changer of the 10kV power transformer, binding of the wire on the 10kV pole on the insulator, and insulation test of the 10kV power cable.

[0032] It should be noted that before the examination and training, personnel need to wear safety equipment for protection. By opening the safety equipment cabinet 1 installed on the base 3, they can take the safety equipment inside for their own protection, and then carry out the examination and training operation. After completing the examination and training operation, the personnel open the safety equipment cabinet 1 again and place the safety equipment back in place. However, when personnel use the safety equipment, their sweat and the like will contaminate the safety equipment, resulting in a sweaty smell in the safety equipment cabinet 1. By starting the exhaust fan 4 installed on the support frame 5 on the inner back of the safety equipment cabinet 1, the odorous air in the small space isolated in the safety equipment cabinet 1 can be discharged from the safety equipment cabinet 1, ensuring the comfort of use for the next batch of personnel. The air is filtered through the filter screen 6 installed on the support frame 5 to prevent external dust and the like from entering the box body;

[0033] After the personnel open the cabinet door of the safety equipment cabinet 1, the pressure sensor 7 installed on the safety equipment cabinet 1 cannot sense the pressure exerted by the cabinet door, thereby starting the lighting lamp 8 installed on the mounting seat 9 at the inner top of the safety equipment cabinet 1 to illuminate the interior of the cabinet, facilitating the personnel to observe the space inside the safety equipment cabinet 1 and conveniently select the safety equipment;

[0034] Since different safety equipment is selected for different assessment questions, when taking the safety equipment in the safety equipment cabinet 1, it is sensed by the gravity sensor 10 installed on the safety equipment cabinet 1. After the personnel take it, the gravity is no longer sensed, and the signal is transmitted to the processor 12 for processing and then through the transmitter 13 installed at the upper end of the safety equipment cabinet 1, the signal is transmitted to the assessment and scoring equipment for scoring. When selecting equipment with a small gravity such as safety clothing, infrared rays are emitted by the infrared transmitter installed in the safety equipment cabinet 1. When it is taken, the infrared rays of the infrared transmitter are no longer blocked, so that it can communicate with the corresponding infrared signal receiver in the box body, and it is determined that lightweight items such as safety clothing are taken and used.

[0035] It should be noted that several air inlets are provided on the safety equipment cabinet 1 to facilitate the inhalation of fresh external air into the cabinet; several spaces with different sizes are isolated in the safety equipment cabinet 1 to facilitate the storage of different safety equipment; and sensors corresponding to the infrared signal transmitters are arranged inside the safety equipment cabinet 1 to facilitate sensing whether the safety equipment in the safety equipment cabinet 1 has been taken.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
