Emergency response method for confluence box fire

1、 Cut off the power supply
       When the combiner box catches fire, the power supply must be cut off first to avoid the generation of electric sparks, which can cause a larger fire. The method of cutting off the power supply can be achieved by disconnecting the fuse or pulling down the switch, and the electricity meter should also be powered off.
2、 Using fire extinguishing equipment
       After cutting off the power supply, purification agents or dry powder fire extinguishers can be used to extinguish the confluence box. When using fire extinguishing equipment, it should be noted not to directly aim the fire extinguishing equipment at the junction box for spraying, in order to avoid causing greater losses. The correct method should be to focus on the ignition point of the combiner box and spray the extinguishing agent in a reverse and oblique direction to ensure that the combiner box is completely within the scope of the extinguishing agent.
3、 Notify professionals
       After taking the above two emergency measures, professional solar photovoltaic system maintenance personnel or firefighters should be notified immediately to handle the fire. The solar photovoltaic system is a high-voltage equipment that requires professional personnel to repair or handle. Notify professionals to be present, which can better ensure the safety of on-site personnel and effectively reduce property and personnel losses caused by fires.
       In short, emergency measures need to be taken to address the fire issue in the combiner box. Firstly, cut off the power supply, then use suitable fire extinguishing equipment to extinguish the fire, and finally notify professional personnel for technical treatment. It is emphasized that during the process of handling a fire, one should always remain calm, accurately evaluate the fire situation, and correctly extinguish the fire.
