Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a switch cabinet with an explosion-proof function. Background Art

[0002] As the name suggests, high and low voltage switchgear is equipment for connecting high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers and then transferred to low-voltage cabinets. The low-voltage cabinets are then transferred to distribution boxes for various electricity users. What is inside is nothing more than some protective devices such as switches and circuit breakers assembled into one electrical equipment.

[0003] At present, in the prior art, a Chinese patent with announcement number CN213460565U discloses a switch cabinet with explosion-proof function. The device can detect the temperature inside the box through a red glass tube. However, the detection area of ​​the red glass tube is limited. When a fire occurs inside, it cannot be broken and started immediately. In view of this, we propose a switch cabinet with explosion-proof function. Utility Model Content

[0012] The utility model provides a switch cabinet with explosion-proof function. It has the following beneficial effects:

[0013] (1) The switch cabinet with explosion-proof function is provided with a floating cover. When a fire occurs in the equipment inside the cabinet, the high-temperature flame heats the surrounding air, causing the hot air to move upward, thereby contacting the contact plate, so that the heat pipe transfers the heat from one end to the other end of the heat pipe, so that the heat passes through the heat dissipation fins to fully heat the kerosene inside the device shell, causing the volume of the kerosene to expand rapidly, thereby causing the floating cover to move upward rapidly, thereby pushing open the push valve, so that the push valve is opened, so that the spray pipe can spray the fire extinguishing liquid into the cabinet, thereby protecting the items inside the switch cabinet.

[0014] (2) The switch cabinet with explosion-proof function can atomize the liquid fire extinguishing liquid through the spray pipe. The multiple groups of strip-shaped atomizing nozzles arranged on the surface of the spray pipe can increase the contact area between the fire extinguishing liquid and the fire source, so that the flame can be quickly wrapped, the temperature of the object is taken away and the surrounding oxygen is isolated, thereby accelerating the fire extinguishing speed of the explosion-proof device.
