Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and in particular to a power distribution cabinet with fire early warning and fire fighting functions. Background Art

[0002] A distribution cabinet is a device used for power distribution and control, and it is an important component of the power system. A distribution cabinet is usually placed in a power room within a building or industrial facility. It integrates various electrical components such as circuit breakers, switches, contactors, fuses, transformers, etc., which work together to distribute power to different loads or equipment. The main function of a distribution cabinet is to control and monitor the power supply while protecting the circuit from faults and abnormal conditions. It can be operated manually or automatically and configured as remote control or local control as needed. Distribution cabinets have a wide range of uses and cover multiple fields. In the field of industrial automation, distribution cabinets are mainly used to control and monitor the operating status of various electrical equipment and production lines; in the field of building intelligence, distribution cabinets are mainly used for power distribution and monitoring in intelligent buildings; in power systems, distribution cabinets are mainly used for monitoring and control of high and low voltage distribution equipment; in the field of transportation, distribution cabinets are mainly used for power supply and control of rail transit vehicles such as subways, light rails, and high-speed railways; in the field of agriculture, distribution cabinets are mainly used for power supply and equipment control of agricultural facilities such as greenhouses and irrigation.

[0003] Some existing power distribution cabinets lack corresponding fire extinguishing mechanisms when in use, and are unable to quickly respond to fire situations and automatically extinguish fires, which easily delays the best time to extinguish the fire.

[0004] For example, a distribution cabinet disclosed in the announcement number CN220527454U has a touch screen protected by a small door and tempered glass that does not affect data monitoring. It is also easy to operate, and the touch screen can achieve good rain and dustproof effects; the distribution cabinet of the patent is equipped with a silent fan to force air to be exhausted outward, and the heat in the cabinet rises. The fan at the top is more conducive to exhausting air outward, so that the temperature in the cabinet is maintained at a more reasonable value. The protective cover can prevent dust or water droplets from falling into the cabinet through the ventilation holes on the top of the cabinet, and the protective cover can also achieve good ventilation and heat dissipation effects; the filter cotton at the bottom of the distribution cabinet of the patent can effectively prevent most dust and rainwater from entering the cabinet, achieving good rain and dustproof effects.

[0005] Although the above-mentioned distribution cabinet is relatively well designed in terms of dustproof, rainproof, ventilation and heat dissipation, and ease of operation, it still has some shortcomings in some aspects. Specifically, the design of the distribution cabinet does not mention any form of automatic or manual fire extinguishing device. Since the distribution cabinet usually contains flammable materials such as electrical components and cables, fires may occur during long-term operation or when encountering electrical failures. If there is no effective fire extinguishing mechanism, once a fire occurs, the fire may spread rapidly, causing serious property damage or even personal injury. In the early stages of a fire, if measures can be taken quickly to extinguish it, the losses can often be significantly reduced. However, since the above-mentioned distribution cabinet is not equipped with a fire extinguishing mechanism, it is unable to respond quickly to the fire situation and automatically extinguish the fire, which can easily delay the best time to extinguish the fire.

[0006] Therefore, it is necessary to invent a distribution cabinet with fire warning and fire fighting functions to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide a power distribution cabinet with fire warning and fire fighting functions to solve the problems in the above technology.
