Problems solved by technology

[0003] Some power distribution cabinets are located in places where people are not densely populated outdoors. Due to direct sunlight and heat reflection on the concrete floor, the heat generated by the equipment in the power distribution cabinet is difficult to dissipate in time. Sometimes the temperature inside the cabinet exceeds 60°C or even higher. High, such a high temperature can easily cause the insulation aging of electrical coils and lead wires to break down and burn out. The contact resistance of electrical contacts will increase due to excessive temperature, and the increase in contact resistance will aggravate heating. Such a vicious cycle will eventually lead to burnout of the contacts. , It is easy to cause serious accidents such as fire, and it is difficult for the outdoor power distribution cabinet to be well monitored by the staff. When a fire occurs, it is not easy to be found and timely artificially extinguish the fire, causing serious economic losses and safety accidents.

Embodiment 1

[0018] Such as Figure 1-2 As shown, an outdoor power distribution cabinet with a rapid self-extinguishing function includes a cabinet body 1, and a partition board 2 arranged horizontally is fixedly installed on the inner wall of the cabinet body 1, and the partition board 2 divides the cabinet body 1 into a fire extinguishing chamber 3 And the installation chamber 4, the inner side wall of the fire extinguishing chamber 3 is sealed and slidably connected with a horizontally arranged sealing plate 5, the lower surface of the sealing plate 5 is fixedly connected with the partition plate 2 through the elastic air bag 6, and the elastic air bag 6 is filled with evaporative liquid, which evaporates The liquid is cyclohexane with a boiling point of 80.7°C. There are two through holes 7 in the sealing plate 5. The middle part of the partition 2 is raised upwards, and a rubber gasket is installed on the upper surface of the partition 2. When it occurs, the elastic airbag 6 is in a n...

Embodiment 2

[0024] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that: the upper end of the threaded rod 9 runs through the top surface of the cabinet 1 and is equipped with a lamp bead 17, and the threaded rod 9 is surrounded by a conductive coil 18, and the lamp bead 17 and Conductive coil 18 is electrically connected, and the top surface of cabinet body 1 is equipped with ring magnet 19.

[0025] In this embodiment, when the threaded rod 9 rotates, it drives the conductive coil 18 to rotate. According to the principle of electromagnetic induction, when the magnetic flux in the closed coil changes, an induced current will be generated in the closed coil, and when the conductive coil 18 rotates, the wire The magnetic flux generated by the ring magnet 19 in the ring 18 changes momentarily, and the induced current generated in the conductive coil 18 supplies power to the lamp bead 17, and the light of the lamp bead 17 can give a warning to the staff,...

Abstract

The invention belongs to the field of power distribution cabinets, and in particular relates to an outdoor power distribution cabinet with fast self-extinguishing function, comprising a cabinet body, and a horizontally arranged partition plate is fixedly installed on the inner side wall of the cabinet body, and the baffle plate The cabinet is divided into a fire-extinguishing cavity and an installation cavity. The inner side wall of the fire-extinguishing cavity is sealed and slidably connected with a sealing plate arranged horizontally. The lower surface of the sealing plate is fixedly connected to the partition through an elastic air bag, and the elastic air bag is filled There is a thermal expansion and cold contraction medium, two through holes are arranged in the sealing plate, and a vertically arranged guide pipe rotates through the baffle plate, and the position of the guide pipe and the two through holes are arranged alternately, The guide tube is provided with a threaded rod arranged along the axial direction thereof. The invention can automatically spray the fire extinguishing agent in the fire extinguishing chamber to the electrical equipment in the installation chamber when a fire occurs in the power distribution cabinet, so as to realize the function of automatic fire extinguishing, which is beneficial to quickly control the fire in the cabinet and reduce economic losses. and the possibility of dangerous accidents.

Description

technical field [0001] The invention belongs to the field of power distribution cabinets, in particular to an outdoor power distribution cabinet with a rapid self-extinguishing function. Background technique [0002] The power distribution cabinet plays the role of on-off, control and protection in power generation, transmission, distribution, power conversion and consumption. It is the final equipment in the power equipment industry. The safe and reasonable use of electric cabinets is becoming more and more important. [0003] Some power distribution cabinets are located in places where people are not densely populated outdoors. Due to direct sunlight and heat reflection on the concrete floor, the heat generated by the equipment in the power distribution cabinet is difficult to dissipate in time. Sometimes the temperature inside the cabinet exceeds 60°C or even higher. High, such a high temperature can easily cause the insulation aging of electrical coils and lead wires to...
