With the continuous development of new energy technology, energy storage cabinets are more and more widely used in the energy field. However, the security issues that come with it are also becoming more and more prominent. In order to ensure the safe operation of the energy storage cabinet, the design of the fire protection system is particularly important.
I. Introduction. With the rapid development of new energy technology, energy storage cabinets are more and more widely used in wind power generation, solar power generation and other fields. However, there are certain safety risks in the use of energy storage cabinets. In the event of a fire, the consequences are unimaginable. Therefore, how to effectively prevent the fire of energy storage cabinet has become the focus of attention in the industry. The fire protection system of the energy storage cabinet is one of the key measures to prevent fire.
Second, the energy storage cabinet fire protection system composition.
1.Detector.
The detector is the "eye" of the fire protection system of the energy storage cabinet and is used to detect the initial stage of a fire. Common detectors are smoke detectors and temperature detectors. The detector converts the perceived fire signal into an electrical signal and transmits it to the alarm controller. When a fire is detected, the detector automatically sends out an alarm signal, providing valuable time for personnel to evacuate and extinguish the fire.
2.Alarm controller.
The alarm controller is the "brain" of the fire protection system of the energy storage cabinet, which is responsible for receiving the signals sent by the detector and processing and judging. Once a fire is detected, the alarm controller will immediately activate the sound and light alarm device to notify the on-site personnel to evacuate quickly. At the same time, the alarm controller will also transmit the fire signal to the fire linkage controller and start the corresponding fire extinguishing measures.
3.Fire extinguishing devices.
The fire extinguishing device is the "fist" of the fire protection system of the energy storage cabinet, which is used to extinguish the fire. Depending on the fire extinguishing needs, different fire extinguishing devices can be selected. For example, for electrical fires, a gas fire extinguishing device can be selected;For liquid fuel fires, foam extinguishing devices are an option;For solid matter fires, dry powder fire extinguishing devices and the like can be selected. Common fire extinguishing devices in energy storage cabinets include gas fire extinguishing devices and dry chemical fire extinguishers.
4.Fire linkage controller.
The fire linkage controller is the "commander" of the fire protection system of the energy storage cabinet, which is responsible for coordinating the work of various fire protection equipment and systems. When the alarm controller sends out a fire signal, the fire linkage controller will immediately start the corresponding fire fighting equipment and systems, such as automatic sprinkler system, smoke exhaust system, etc., to minimize the loss caused by the fire. At the same time, the fire linkage controller will also transmit the fire signal to the fire department so that external support can be received in time.
