The photovoltaic box transformer is one of the core components of the solar photovoltaic power plant system, and its main function is to convert the direct current generated by the photovoltaic panels into alternating current that can be transmitted to the grid. In recent years, with the rapid development of the photovoltaic industry, the fire problem of photovoltaic power stations has gradually become a hot topic in the industry and has received more attention from the society.
Photovoltaic power station box fire detector pipe fire extinguishing device
The existing photovoltaic power station box transformer automatic fire extinguishing device adopts a temperature-sensing self-starting fire extinguishing device, that is, a fire detection tube type automatic fire extinguishing system, and the fire extinguishing device is when the ambient temperature reaches the starting temperature of the fire detector tube or is burned off by contacting an open flame, the fire detector tube will start the fire extinguishing agent inside the fire extinguishing device to be sprayed out rapidly, and the fire extinguishing is carried out quickly. At the same time, it also needs to be linked with the control room, so that the staff can observe the situation of the photovoltaic box at any time. Today, we will discuss the advantages and disadvantages of the fire extinguishing device of the photovoltaic power station box transformer fire detector.
1. Advantages
(1) Space saving: Compared with the traditional cabinet and pipe network fire extinguishing system, the pipes and equipment of the fire detector tube automatic fire extinguishing system are relatively simple, occupy less space, and have less impact on the layout of the box transformer.
(2) Precise fire extinguishing: The fire detector tube uses a flexible and flexible fire detector tube as the alarm component of the fire, and the fire detector tube can also be used as a transmission and release pipeline for the fire extinguishing agent, which is directly arranged near each potential fire point, which can accurately release the fire extinguishing agent to the fire area and improve the fire extinguishing effect.
(3) Rapid response: The system can quickly detect the fire source in the early stage of the fire, and automatically start the fire extinguishing device to extinguish the fire in time and reduce losses.
(4) Simple device: without any power supply, special fire detectors, complex equipment and pipelines, it integrates alarm and fire extinguishing, and is a low-cost, simple structure and highly reliable fire extinguishing device.

2. Disadvantages
(1) Air leakage and pressure loss: Affected by the quality of inspection standards and market competition, the quality of such products on the market is generally unstable, easy to leak and lose pressure, and follow-up maintenance is more troublesome.
(2) Risk of false alarms: The sensitivity of the fire detector may lead to false alarms, especially in environments where there are interference factors, false alarms may cause unnecessary panic or interfere with normal production activities.
(3) Limitations: The fire detector tube automatic fire extinguishing system is usually only suitable for small protection areas, and may not be able to completely cover or effectively control the fire for larger spaces or complex fire situations.
The fire extinguishing device of photovoltaic power station box transformer is a relatively mature product on the market at present, and it is also a scheme that will be adopted by the owner unit or the design institute. However, because of the risk, our company has designed a special SV· FIRE intelligent automatic fire extinguishing device can make up for the risk of air leakage and pressure loss and false alarm of the fire detector pipe, ensure the stability of the whole set of automatic fire extinguishing device, and the product has 3C certification and report to meet the needs of the owner and customer fire acceptance.

The box transformer of the photovoltaic power station is generally an unguarded place, and the scheme will be equipped with an electrical fire detection system and an intelligent detection system at the same time, and there will also be linkage with the fire control center and wireless transmission functions to ensure the integrity of the whole system. Since there is no special fire protection design specification for photovoltaic power stations, Nianhai Fire has discussed the advantages and disadvantages of the fire extinguishing device scheme of photovoltaic power station box transformer fire detector according to some project experience and on-site investigation, and thus designed a set of intelligent automatic fire extinguishing device solutions for photovoltaic power station box transformer, hoping to provide reference and ideas for you.
