The installation process is cumbersome and time-consuming, and has high requirements on production sites and human resources, which is not conducive to rapid deployment and maintenance.

[0004] Insufficient fire resistance: It is difficult to withstand high temperature environments and is prone to failure in fire or high temperature conditions, causing power outages or even more serious safety accidents.

[0005] Limited protection capability: Most traditional busbar systems have low dust and water resistance levels and cannot cope with harsh environmental conditions. They are easily invaded by dust, moisture and other substances, affecting the normal operation of the system.

[0006] Poor earthquake resistance: When natural disasters such as earthquakes occur, problems such as damage and loosening may occur, affecting the stability of power supply.

[0007] Lack of escape warning function: Traditional systems have problems such as long response time and inaccurate warnings, and are unable to provide timely and effective escape guidance to personnel in emergency situations.

[0008] Low energy efficiency: The traditional busbar system is inefficient, resulting in a large amount of energy waste and does not meet the needs of sustainable development.

[0009] Lack of environmental perception and self-repair capabilities: It is difficult to accurately perceive complex environmental changes and self-repair faults in a timely manner, resulting in insufficient system reliability and stability.

[0010] Weak data processing and monitoring functions: It is impossible to achieve real-time and accurate monitoring of the system operation status and fault prediction, which increases the risk of system operation and maintenance costs.

[0054] Example:

[0055] In a power transformation project of a large chemical plant, the installation of this intelligent fire-resistant escape warning photoelectric busbar system was implemented. First, the wiring scheme of the busbar system was designed according to the power layout and load requirements of the chemical plant. The busbar body was laid according to the predetermined route, and it was ensured to be firmly installed to reduce the impact of vibration and displacement. Then, the outside of the busbar body was carefully constructed to wrap the refractory material layer to ensure uniform thickness and no gaps to provide reliable fire protection. Then, each module was installed in turn to ensure that the connection line was correct and the communication was stable. The sensors and controllers of the intelligent monitoring module were accurately installed in key positions, and the alarms, voice broadcasters and indicator lights of the escape warning module were reasonably distributed to facilitate clear perception in emergency situations. Other modules such as the data processing unit, emergency lighting module, and intelligent positioning module were also accurately installed according to the design requirements, and preliminary debugging and testing were carried out.

[0056] In order to verify the performance and effect of this system, a series of experiments and data collection were carried out, and compared with traditional busbar systems and other similar products:

[0057]

[0058]

[0059] The installed busbar system was placed in a high-temperature environment simulation device, and the temperature was gradually raised to 2500°C for 2 hours. During this period, the temperature changes of the busbar body and the refractory layer were monitored in real time through the built-in temperature sensor. The results showed that during the 2-hour high-temperature test, the temperature of the busbar body was always kept within the safe range, and the refractory layer did not show obvious damage or performance degradation. However, the traditional busbar system showed performance degradation or even damage at temperatures far lower than this system.

[0060] The busbar system was placed in a dustproof and waterproof test box to conduct an IP68 protection performance test. After a long period of immersion and dust invasion, there was no water or dust ingress into the system, and all performances were normal. In contrast, the protection level of the traditional busbar system is low, and problems such as water and dust ingress occurred during the test, affecting normal operation.

[0061] On the simulated earthquake platform, the busbar system was subjected to a vibration intensity of a magnitude 9 earthquake. During the test, the system remained stable without any loose, falling or damaged components. However, traditional busbar systems experienced problems such as loose components and unstable operation at lower earthquake resistance levels.

[0062] The busbar system was placed in a salt spray test chamber for 1,800 hours of continuous testing. After the test, the metal parts on the surface of the system had only slight corrosion marks, which did not affect normal operation. However, the traditional busbar system showed more serious corrosion in a shorter salt spray test time.

[0063] In the simulated fire scene, different concentrations of smoke are released. When the smoke concentration reaches the set threshold, the escape warning module responds quickly, the alarm response time meets the design requirements, the voice broadcast is clear and accurate, and the indicator light is bright and eye-catching. The traditional busbar system has a long escape warning response time, which may delay the escape opportunity.

[0064] By simulating various operating conditions of the busbar system, including current fluctuations and voltage changes, the intelligent monitoring module can accurately collect data in real time, and the data processing unit can quickly process and analyze the data to provide accurate diagnosis and decision support. The data collection and processing capabilities of traditional busbar systems are relatively weak, making it difficult to quickly and accurately diagnose faults.

[0065] Under normal operating conditions, the input and output power of the energy recovery module were measured and the recovery efficiency was calculated. The results showed that the recovery efficiency reached more than 80%, which was in line with the expected design. However, the energy recovery efficiency of the traditional busbar system is low, resulting in a large waste of energy.

[0066] By simulating different environmental conditions, such as changes in temperature, humidity, and concentration of harmful gases, the environmental perception module can accurately detect and feedback data. At the same time, by artificially creating some faults, the self-repair module can complete the repair within the specified time, and the repair success rate reaches more than 85%. In contrast, the environmental perception error of the traditional busbar system is large, the self-repair function is weak, and the fault repair success rate is low.

[0067] In the critical moment of a fire, the fire warning voice broadcast function of this intelligent fire-resistant photoelectric bus system becomes a key factor in protecting the lives of personnel. When smoke or high temperature is detected by the system's environmental perception module, the voice broadcaster will quickly emit a clear, distinct and powerful voice;

[0068] "Please note that a fire has occurred. Please evacuate quickly in the direction of the escape indicator light!" This is not only a simple warning, but also points out the direction of survival for people in panic and confusion. The voice broadcast content will be continuous and repeated to ensure that it can be clearly heard even in a noisy and chaotic environment;

[0069] Different from the vague or single alarm sound of the traditional busbar system, our voice broadcast will inform people in detail the location of the nearest escape exit, the direction of the safe passage and other important escape guidance information. For example: "The emergency escape exit is 50 meters ahead, please go there in an orderly manner!", "Please avoid the dangerous area on the left and turn right to evacuate!";

[0070] Moreover, the system can dynamically adjust the content of the voice broadcast according to the real-time development of the fire and the distribution of personnel. If the fire spreads rapidly in a certain area, the voice broadcast will promptly remind: "This area is dangerous, please do not approach, please evacuate immediately in the opposite direction!";

[0071] This accurate, timely and user-friendly fire warning voice broadcast assisted escape function greatly improves the success rate of escape in fire and wins precious time for life safety.

[0072] This intelligent fire-resistant escape warning photoelectric busbar system provides a new solution for the field of power transmission through innovative design and advanced technology integration. In practical applications, it has demonstrated excellent performance and significant advantages, effectively protecting the safety of life and property of personnel and improving the reliability and stability of the power system.

[0073] In the future, as technology continues to advance and market demand grows, we will continue to optimize and improve the system, improve its performance and functions, and expand its application areas. At the same time, we will strengthen cooperation and exchanges with related industries, promote the development of intelligent power transmission technology, and make greater contributions to building a safer, more efficient, and more intelligent power system.

Many modifications and variations will be apparent to those of ordinary skill in the art.
