Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.
A group of putting out a fire in high-low voltage switch cabinet, the description attached drawing is shown in figure 1, major structure connects electric junction awl sheath 7, sets up at the inboard automatic extinguishing device of cabinet door 1 including setting up distribution switch 14 in wire and cabinet.
The cone sheath 7:
the fire extinguishing group in the cabinet also comprises a cone sheath 7; the cone sheath 7 plays a role in moisture-proof and fire-extinguishing. The cone sheath 7 is arranged at the electric connection position of a lead and a distribution switch 14 in the cabinet, the center of the cone sheath 7 is a threading chamber 8, the periphery of the cone sheath is an annular gas chamber 9, and carbon dioxide gas is filled in the gas chamber 9; after the puncture is inflated, the puncture opening is sealed by the patch sticker 15, so that air leakage is avoided. The cone sheath 7 is provided with a notch 10; a layer of desiccant coating 11 is attached to the inner wall of the threading chamber 8. The top of the threading chamber 8 is a cylindrical upper chamber 12, and the bottom is a trapezoidal lower chamber 13. After the tail end of the lead is electrically connected with the power distribution switch 14 through a screw, the tail end of the lead connected with the power distribution switch 14 is covered into the threading chamber 8 from the notch 10 on the cone sheath 7, and the lower cavity 13 is wider in order to adapt to the screw. The desiccant coating 11 is attached to the inner wall of the threading chamber 8 to absorb water and prevent moisture, and corrosion and aging of the wiring position are avoided. If the tail end of the lead and the distribution switch 14 catch fire due to short circuit and the like, after the outer wall of the air chamber 9 adhered to the drying agent cladding 11 is burnt by small fire, carbon dioxide gas flushed in the air chamber 9 is sprayed out, so that the fire is extinguished, the fire can be extinguished from the beginning of the fire, and the fire is prevented from spreading.
Automatic change extinguishing device:
the automatic fire extinguishing device comprises an air chamber 2 arranged on the inner side of a cabinet door 1, a one-way inflation valve 3 arranged on the wall of the air chamber 2, a smoke detector electromagnetic valve 4 and a flow dividing chamber plate 5. Cabinet door 1 is hollow form cabinet door 1, and the inside hollow storehouse of cabinet door 1 is gas storehouse 2, and cabinet door 1 just can act as the gas cylinder and use, does not occupy the cabinet inner area, sets up more rationally, is filled with compressed carbon dioxide gas in the gas storehouse 2. The one-way inflation valve 3 is welded on an air inlet hole on the wall of the air bin 2 at the inner side of the cabinet door 1; the smoke detector electromagnetic valve 4 is arranged on the surface of the gas bin 2, and the smoke detector electromagnetic valve 4 is communicated with a gas outlet hole in the wall of the gas bin 2 on the inner side of the cabinet door 1. The flow distribution bin plate 5 is connected with the gas bin 2 through a smoke sensor electromagnetic valve 4, and the flow distribution bin plate 5 is provided with a gas orifice 6. The distribution chamber plate 5 is inserted into the chamber with a certain width, thereby ensuring that the gas sprayed from the gas orifice 6 can directly act on the ignition point. And the arrangement position of the shunt chamber plate 5 is always matched with the position of the wiring position. When carbon dioxide can't put out a fire in the air chamber 9, can produce a large amount of smog after the fire disaster in the cabinet storehouse, can control smoke detector solenoid valve 4 to open after smoke detector 4's on cabinet door 1 smoke detector solenoid valve 4 detects smoke signal, makes the air flue intercommunication between gas storehouse 2 and the reposition of redundant personnel storehouse board 5 to make the carbon dioxide gas in the gas storehouse 2 put out a fire from the blowout of fumarole 6, avoid arousing the risk of large-scale conflagration. The risk of causing a large fire is avoided.
The bottom of the cabinet cavity of the cabinet body is provided with an air ventilation net 16, the bottom of the cabinet body is provided with an air ventilation bin 172, and the air ventilation net 16 is communicated with the outside through the air ventilation bin 172. Carbon dioxide gas is sprayed out from the gas spraying holes 6 to extinguish fire, then the air pressure in the cabinet cavity is increased, and therefore high-temperature smoke in the cabinet cavity is discharged to the outside through the ventilation net 16 and the ventilation bin 172 in sequence, and the fire is prevented from recurring.
Further technical limitation:
the smoke sensor electromagnetic valve 4 is powered by a non-cabinet power supply device; when the high-low voltage cabinet is used in outdoor field areas, the power supply device in the non-cabinet is a solar power supply device. When the high-low voltage cabinet is used in a power distribution room, the power supply device in the non-cabinet is a storage battery device. The reason why the power supply device in the cabinet is not used for supplying power is that: after a small fire occurs and before the smoke sensor electromagnetic valve 4 works, if a power supply device in the cabinet is damaged by the small fire, the smoke sensor electromagnetic valve 4 cannot work normally, and the automatic fire extinguishing device fails, so that large-scale fire and loss are caused.
In conclusion, the device is an in-cabinet fire extinguishing group with double fire extinguishing protection, when the tail end of the lead and the distribution switch 14 catch fire due to short circuit and other reasons, when a small fire just occurs, the small fire breaks through the outer wall of the air chamber 9 adhered to the drying agent cladding 11, and then carbon dioxide gas flushed in the air chamber 9 is sprayed out, so that the fire is extinguished, the fire can be extinguished from the beginning of the fire, and the fire spread is avoided. When awl sheath 7 can't accomplish thoroughly putting out a fire, can produce a large amount of smog behind the cabinet storehouse fire disaster, can control smoke detector solenoid valve 4 to open after smoke detector solenoid valve 4's on cabinet door 1 smoke detector detects smoke signal, makes the air flue intercommunication between gas storehouse 2 and the reposition of redundant personnel storehouse board 5 to make the carbon dioxide gas in the gas storehouse 2 put out a fire from 6 blowout of fumarole, avoid arousing the risk of large-scale conflagration.
