Description

Technical Field

[0001] This application relates to the technical field of low-voltage switch cabinets, and specifically to a low-voltage switch cabinet with a heat dissipation function. Background Art

[0002] A low-voltage switch cabinet is a device used to control, distribute, and protect circuits. It is usually installed in a power system to manage the flow of electricity and protect electrical equipment from overload, short circuit, and other electrical faults. A low-voltage switch cabinet usually contains various switches, circuit breakers, protection devices, meters, and control equipment to ensure the safe operation of the power system. Usually, when a low-voltage switch cabinet operates at a high load, it will generate high temperature. If the low-voltage cabinet does not dissipate heat, it may cause the internal electrical equipment to overheat due to long-term high temperature, resulting in equipment damage and also posing a risk of fire.

[0003] In the patent with the patent number CN213584677U, the cabinet door is closed by pulling a straight handle and opened by turning a crank, so that the direction of opening and closing the cabinet door is the vertical up and down direction, avoiding the waste of space caused by the lateral opening or closing of the cabinet door, thus reducing the cost of building a distribution room.

[0004] Although the above patent can adjust the cabinet door, it is difficult to dissipate heat inside the box body. If the low-voltage cabinet does not dissipate heat, it may cause the internal electrical equipment to overheat due to long-term high temperature, resulting in equipment damage. Overheating will also affect the working stability of the electrical equipment, causing the equipment to operate abnormally, trip frequently, or cause line faults, and thus leading to a fire. Therefore, a low-voltage switch cabinet with a heat dissipation function is needed. Summary of the Utility Model

[0036] All the electrical equipment in this solution is powered by an external power supply.

[0037] Working principle: When the low-voltage switchgear with heat dissipation function is in use, by starting the heat dissipation component 20, the exhaust fan 203 is driven to rotate, so that the external air is blown into the box body 1, keeping the equipment within the appropriate working temperature range. During heat dissipation, the wind passes through the filter screen 213 in the dust cleaning component 21, effectively blocking and purifying the impurities in the wind, preventing dust from entering the box body 1 and avoiding the accumulation of dust on the circuit causing a short circuit. By retracting the fixing mechanism 3, the four universal wheels 34 come into contact with the ground, enabling the device to be moved, making the device flexible. When dissipating heat, by starting the exhaust fan 203, the external air is drawn into the inside of the air extraction box 201 through the air inlet 202 for dissipating heat from the inside of the box body 1.

Through multiple air outlet holes 205, air is blown into the box body 1 to achieve the heat dissipation function. By manually pulling the pull-out frame 212, the pull-out frame 212 slides inside the pull-out groove 211 for replacing the filter screen 213 inside the pull-out frame 212, preventing the filter screen 213 from being blocked by dust due to long-term non-replacement. By starting the electric telescopic rod 32, the anti-slip pad 33 is driven to contract, making the universal wheels 34 contact the ground for moving the device, effectively improving flexibility. By the staff holding the handle 5 and pulling forward, the cabinet door 4 is opened to facilitate the staff for maintenance. With the two installed cabinet doors 4, it is more convenient and faster for the staff during maintenance. The multiple air outlet openings 6 are provided for discharging hot air.
