As a high-safety perimeter protection system integrating physical barriers and intelligent alarm functions, the electric charging pulse electronic fence requires multiple technical means and standardized operation to ensure safety during the charging process. The charging process involves core aspects such as high-voltage pulse generation, energy storage, and transmission. Inadequate protective measures may lead to risks such as electric shock, electrical fires, or equipment malfunctions. Therefore, the system needs to construct a protection system from five dimensions: electrical safety design, environmental isolation, operating procedures, equipment maintenance, and emergency response.
Electrical safety design is the foundation of charging protection. The charging module of the electric charging pulse electronic fence must adopt an isolated high-voltage terminal design to ensure that no conductive circuit is formed upon human contact. For example, if an operator accidentally touches the fence cables, the isolation structure can block the current conduction path, preventing electric shock. In addition, the charging circuit must integrate overvoltage protection, overcurrent protection, and leakage protection devices. Overvoltage protection prevents abnormal voltage rises that could damage the equipment; overcurrent protection limits the current to a safe range; and leakage protection immediately cuts off the power supply when leakage occurs by monitoring current differences in real time. These protection mechanisms together constitute a "triple line of defense" for electrical safety, reducing charging risks from the source. Environmental isolation is crucial to prevent interference from external factors. During charging, the front of the fence must be kept away from fire hazards such as haystacks and areas with flammable materials to avoid open flames caused by electrical faults. For example, if fence cables come into contact with hay, the localized high temperature may ignite flammable materials, while maintaining a safe distance can effectively prevent the spread of fire. Simultaneously, it is necessary to prevent plants from growing upwards along the fence. If plant branches and leaves come into contact with high-voltage cables, they may cause leakage due to moisture or short circuits due to conductivity. Therefore, vegetation around the fence should be cleaned regularly, or anti-climbing designs should be adopted, such as installing smooth insulating boards to block plant growth paths. Furthermore, charging equipment should be installed in a rainproof and dustproof dedicated enclosure to prevent rainwater seepage leading to short circuits or dust accumulation affecting heat dissipation.
Proper operating procedures are core to ensuring personnel safety. Charging operations must be performed by qualified personnel. Before operation, insulated gloves, insulated shoes, and other protective equipment must be worn, and insulated tools must be used for wiring connections. For example, when connecting charging interfaces, insulated tools can prevent operators from directly contacting live parts, reducing the risk of electric shock. During charging, unauthorized personnel are strictly prohibited from approaching the fenced area, especially children or pets, to avoid accidental contact and potential hazards. If equipment inspection is required during charging, the power must be disconnected first, and a "Do Not Operate" warning sign must be displayed to prevent accidental operation. Furthermore, charging should be avoided during thunderstorms, strong winds, and other severe weather conditions to prevent lightning strikes or strong winds that could cause equipment vibration and poor contact.
Equipment maintenance is crucial for extending system lifespan. Charging modules should be regularly checked for loose connections. Loose connections can increase resistance, leading to overheating and potentially a fire. For example, a loose charging cable connection to the host interface can increase contact resistance, potentially generating sparks that could ignite surrounding flammable materials. Simultaneously, battery performance must be tested to ensure its capacity and internal resistance meet standards. Aging batteries may cause safety issues due to internal short circuits or electrolyte leaks and must be replaced promptly. Additionally, dust and debris on the charging module surface must be cleaned to maintain unobstructed heat dissipation and prevent performance degradation or damage due to overheating.
Emergency response is the last line of defense in mitigating accident losses. Charging areas must be equipped with emergency equipment such as fire extinguishers and insulating rods, and warning signs such as "High Voltage Danger" and "Do Not Touch" must be posted. These signs must be made of reflective material to ensure visibility at night. In the event of an electric shock, the power must be immediately cut off, an insulating rod used to separate the person from the live conductor, and emergency medical services called. In the event of an electrical fire, a dry powder fire extinguisher must be used; water must never be used to extinguish the fire to prevent further electric shock. Furthermore, the system must integrate remote monitoring capabilities, transmitting charging status, voltage, and current data to the management platform in real time. If any abnormalities are detected, such as excessively high charging voltage or abnormal current fluctuations, the platform can automatically trigger an alarm and notify maintenance personnel for timely handling.
