[0003] In use, electrical fire is one of the most dangerous hidden dangers of electrical cabinet.Due to the large number of electrical components inside the electrical cabinet, if the line contact is poor, equipment failure, equipment aging, overload or short circuit occurs, arc or electric spark is easily generated, thereby causing fire.Especially in high temperature, dry environment, the risk of fire will further increase;The existing electrical cabinet fire extinguishing system usually adopts the way of configuring fire extinguisher (usually hand-held dry powder fire extinguisher or carbon dioxide fire extinguisher) or configuring fire sprinkler system (usually water sprinkler or heptafluoropropane pipe network system) as the main means of electrical cabinet fire extinguishing.
[0004] Among them, the way of configuring fire extinguisher does not have the ability of fire detection, mainly relies on manual observation, and the implementation of fire extinguishing also needs manual operation, so there are problems of slow fire extinguishing response and low fire extinguishing efficiency;And the way of configuring fire sprinkler system has the advantages of autonomous fire detection and no longer needs manual intervention in the implementation of fire extinguishing, and is widely used in electrical room projects with high fire protection requirements;But since the electrical cabinet fire often starts from the inside of individual electrical cabinet in electrical room, it is difficult for the fire detection function of fire sprinkler system to quickly and accurately identify early fire, and the fire extinguishing agent of sprinkling is difficult to quickly enter the inside of electrical cabinet, so the way of configuring fire sprinkler system still cannot completely solve the problems of slow fire extinguishing response and low fire extinguishing efficiency existing in the existing electrical cabinet fire extinguishing system.

[0015] Further, the power supply module is fixedly installed on the bottom of the shell of the electrical cabinet.
[0016] Further, the electrical cabinet fire-fighting device further comprises an audible and visual alarm installed on the outer side of the shell of the electrical cabinet, and the audible and visual alarm is used to generate audible and visual alarm according to the fire abnormal signal sent by the detector assembly.
[0017] By arranging the audible and visual alarm, the audible and visual alarm can be generated in time to prompt the relevant personnel of the fire when the fire occurs in the electrical cabinet.
[0018] Further, the detector assembly is fixedly installed on the top of the shell of the electrical cabinet.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0028] Example 1:
[0029] like Figure 1 As shown, this embodiment 1 provides an electrical cabinet fire protection device, including a fire protection module 1 installed on the outside of the electrical cabinet 9's housing, a controller 4 installed on the electrical cabinet 9's housing, a fire protection pipe 6, and a nozzle 5 and a detector assembly installed inside the electrical cabinet 9's housing; the fire protection module 1 is connected to the nozzle 5 through the fire protection pipe 6, the detector assembly is used to monitor fire anomalies inside the electrical cabinet 9, and the controller 4 is used to control the fire protection module 1 to inject fire extinguishing agent into the electrical cabinet 9 according to the fire anomaly signal sent by the detector assembly.
[0030] By placing the detector assembly inside the electrical cabinet 9, the fire-fighting device for the electrical cabinet provided by this utility model can quickly and accurately identify early-stage fires occurring inside the electrical cabinet 9. Then, by using the controller 4 to control the fire-fighting module 1 to inject extinguishing agent into the electrical cabinet 9 based on the fire anomaly signal sent by the detector assembly, a rapid fire-fighting response to early-stage fires occurring inside the electrical cabinet 9 can be achieved, which can effectively improve the fire-fighting efficiency and solve the technical problems of slow fire-fighting response and low fire-fighting efficiency in the existing fire-fighting system for electrical cabinet 9.
[0031] Preferably, in this embodiment 1, the fire-fighting module 1 is a perfluorohexanone fire extinguishing device.
[0032] By configuring fire-fighting module 1 as a perfluorohexanone fire extinguishing device (i.e., the fire extinguishing agent configured in fire-fighting module 1 is perfluorohexanone), the advantages of perfluorohexanone, such as no residue after fire extinguishing, cleanliness, good electrical insulation properties, and no damage to electrical components in electrical cabinet 9, are fully utilized.

It can also avoid the situation where other well-functioning electrical cabinets 9 come into contact with water and short circuits occur, causing greater losses. It can also avoid the environmental pollution problems that heptafluoropropane may cause. High-pressure stored heptafluoropropane is prone to pressure leakage and bottle bursting during transportation, installation, and operation. In addition, the heptafluoropropane bottle itself is too bulky, and the transportation and installation risk factors are too high.
[0033] Preferably, in this embodiment 1, nozzle 5 is a perfluorohexanone atomizing nozzle.
[0034] By configuring the nozzle 5 as a perfluorohexanone atomizing nozzle, the spraying and atomization of the perfluorohexanone can be facilitated, so that the perfluorohexanone extinguishing medium can quickly fill the fire protection space inside the electrical cabinet 9, further improving the fire extinguishing efficiency.
[0035] In one of the embodiments, as shown in Figure 1 The electrical cabinet fire extinguishing device further comprises a power supply module 8 installed in the electrical cabinet 9, and the fire extinguishing module 1, the controller 4 and the detector assembly are electrically connected with the power supply module 8.
[0036] By setting the power supply module 8 to provide power for the fire extinguishing module 1, the controller 4 and the detector assembly, the normal and orderly work of each component can be ensured.

[0044] Embodiment 2:
[0045] According to the electrical cabinet fire extinguishing device provided in the embodiment 1, the embodiment 2 provides an electrical system comprising a plurality of electrical cabinet units installed in an electrical room, and each electrical cabinet unit comprises an electrical cabinet 9 and the electrical cabinet fire extinguishing device provided in the embodiment 1 (as shown in Figure 1
[0046] The electrical cabinet fire-fighting device of the electrical cabinet unit is mounted on the shell of the electrical cabinet 9 of the electrical cabinet unit.
[0047] The electrical cabinet fire-fighting device and the electrical system have at least the following technical effects or advantages:

[0049] 2. By configuring the fire-fighting module 1 as a perfluorohexone fire extinguishing device (i.e. the fire extinguishing agent arranged in the fire-fighting module 1 is perfluorohexone), the advantages of perfluorohexone, such as no residue after fire extinguishing, cleanliness, good electrical insulation performance, and no damage to electrical components in the electrical cabinet 9, are fully utilized. Compared with the existing electrical cabinet 9 fire extinguishing system which usually uses water or heptafluoropropane as fire extinguishing agent by configuring a fire sprinkler system, while ensuring self-detection of fire and automatic execution of fire extinguishing action, the situation of short circuit and greater loss caused by contact of other well-operating electrical cabinets 9 with water can be avoided, and the environmental pollution problem caused by heptafluoropropane can also be avoided. The high-pressure stored heptafluoropropane is prone to pressure leakage and bottle body burst during transportation, installation and operation, and the heptafluoropropane bottle body itself is too heavy, which has a high risk coefficient during transportation and installation.
