Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bus duct, in particular to a bus duct with side plate heat dissipation. BACKGROUND

[0002] With the emergence of modern engineering facilities and equipment, the power consumption of various industries increases rapidly, especially the increase of high-rise buildings and large workshops and other places. Traditional cables as power transmission conductors are difficult to meet the requirements in large current transmission systems, and the use of multiple parallel cables also brings many inconveniences to on-site installation and construction connection. At the same time, the traditional pipe-through circuit wiring method is difficult to construct, and it is also very inconvenient to change the power distribution system. Under this background, bus duct emerges as the times require, which has obvious advantages in large current transmission, and uses new technology and new process to reduce contact resistance and temperature rise and improve safety and reliability.

[0003] Although the existing bus duct side plate can guide the heat generated during line operation through the heat dissipation fins, the heat dissipation fins rely on natural convection or forced air cooling to take away heat. If the air is not flowing (such as airtight space, windless environment), a thermal boundary layer will be formed around the fins, which is not conducive to heat loss. Moreover, if it is in a high temperature environment, the temperature difference between the heat dissipation fins and the environment is reduced, the heat conduction power is reduced, and the local temperature of the bus duct may be too high, which may cause interphase short circuit or discharge to ground, causing equipment damage and even fire.

[0004] In view of the above problems, it is urgent to make innovative design on the basis of the original. SUMMARY

[0041] The heat dissipation fins rely on natural convection or forced air cooling to take away heat. If air does not circulate, a thermal boundary layer will form around the fins, which is not conducive to heat loss. The specific implementation is as follows. In use, first, external gas is injected into the air pipe 3. At this time, the gas enters the cooling pipe 4 through the first connecting pipe 11. The gas in the cooling pipe 4 is sprayed out through the surface leakage hole to cool the heat dissipation fins on the surface of the groove side plate 2. Then, the controller drives the electric push rod 6 to operate. The extended end of the electric push rod 6 drives the strip-shaped plate 7 to move back and forth. At this time, the cooling pipe 4 can swing back and forth when spraying gas.

[0042] When the external temperature is high, the temperature sensor senses that the temperature inside the groove side plate 2 is high. At this time, the controller drives the rotating rod 149 to rotate through the motor. The rotating rod 149 drives the abutting block 148 to move inside the air pipe 3, so that the abutting block 148 extrudes the first pressing plate 141 and the opening and closing block 144. Then, the controller drives the motor to stop rotating. The top of the abutting block 148 extrudes the first pressing plate 141, driving the closing block 142 to move upwards, reducing the gap between the first connecting pipe 11 and the closing block 142. The right side of the abutting block 148 extrudes the second pressing plate 143, driving the opening and closing block 144 to move to the right. At this time, a gap is generated between the opening and closing block 144 and the second connecting pipe 13. At this time, part of the gas in the air pipe 3 enters the cooling pipe 4 through the first connecting pipe 11, and the other part enters the cavity of the groove side plate 2 through the second connecting pipe 13. At this time, the airflow in the cavity of the groove side plate 2 is sprayed out through the top gap, discharging the heat accumulated in the groove side plate 2;

[0043] As one of the embodiments of the present application, the cooling adjusting mechanism comprises a limiting groove 902 opened in the cavity side wall of the groove side plate 2 and a mounting table 903 fixed on the cavity side wall of the groove side plate 2, the bottom end of the air deflector 8 is rotationally connected with an adjusting rod 901, a thin rod is vertically and limitingly slid in the mounting table 903, a top block 904 is mounted on the bottom of the thin rod, and an extrusion block 905 is limitingly slid in the cavity of the groove side plate 2, so that the gas loss speed in the side plate is gradually slowed down when the external temperature gradually rises, and the time of the gas flow staying in the side plate is prolonged;

[0044] As one of the embodiments of the present application, the mounting table 903 is inclined on the surface of the side wall of the groove side plate 2, the adjusting rod 901 is limitingly slid in the mounting table 903, a spring is sleeved on the surface of the top end of the thin rod of the extrusion block 905, the bottom end of the spring is connected with the bottom of the mounting table 903, a sliding block is connected with the top end of the thin rod, the sliding block is limitingly slid in the groove in the bottom of the adjusting rod 901, the bottom of the top block 904 is semicircular, a slope is opened on the surface of the extrusion block 905, the slope of the extrusion block 905 abuts against the bottom of the top block 904, a groove is opened on the side end of the second air deflector 12, a straight rod is mounted on the side end of the opening and closing block 144, the straight rod is limitingly slid in the groove on the side end of the second air deflector 12, and the other end of the straight rod is connected with the extrusion block 905.

[0045] Working principle: when working, the external gas is first injected into the air pipe 3, at this time, the gas enters into the cooling pipe 4 through the first connecting pipe 11, the gas in the cooling pipe 4 is sprayed out through the surface leakage hole to cool the surface fin of the groove side plate 2, then the electric push rod 6 is driven to work by the controller, the stretching end of the electric push rod 6 drives the strip-shaped plate 7 to reciprocate, at this time, the cooling pipe 4 can reciprocate when spraying gas;

[0046] When the external temperature is high, the temperature sensor senses that the temperature in the cavity of the groove side plate 2 is high, at this time, the controller drives the rotating rod 149 to rotate through the motor, the rotating rod 149 drives the abutting block 148 to move in the air pipe 3, so that the abutting block 148 extrudes the first pressing plate 141 and the opening and closing block 144, then the motor is driven to stop rotating by the controller, the abutting block 148 extrudes the first pressing plate 141 on the top, drives the closing block 142 to move upwards, reduces the gap between the first connecting pipe 11 and the closing block 142, the abutting block 148 extrudes the second pressing plate 143 on the right side, so that the opening and closing block 144 is driven to move to the right, at this time, the opening and closing block 144 and the second connecting pipe 13 form a gap, at this time, part of the gas in the air pipe 3 enters into the cooling pipe 4 through the first connecting pipe 11, and the other part enters into the cavity of the groove side plate 2 through the second connecting pipe 13, at this time, the gas flow in the cavity of the groove side plate 2 is sprayed out through the top gap, and the heat accumulated in the groove side plate 2 is discharged;

[0047] While the first pressing plate 141 drives the closing block 142 to move upwards, the closing block 142 drives the top frame 146 to move upwards, at this time, the top frame 146 upwardly abuts against the adjusting plate 145, so that the adjusting plate 145 moves upwards in the cooling pipe 4, since the surface leakage hole of the adjusting plate 145 is dislocated with the surface leakage hole of the cooling pipe 4, the pressure of the air flow sprayed from the cooling pipe 4 is increased, while the second pressing plate 143 drives the opening and closing block 144 to move rightwards, the opening and closing block 144 drives the extruding block 905 to move into the cavity of the groove side plate 2, the extruding block 905 moves to extrude the top block 904 to move upwards, the extruding block 905 moves upwards to drive the adjusting rod 901 to slide in the limiting groove 902, so that the air deflector 8 deflects in the groove side plate 2, at this time, the deflected air deflector 8 can slow down the speed of the air flow loss of the groove side plate 2, so that more heat can be carried and lost, at the same time, the controller drives the electric push rod 6 to move, so that the extension end of the electric push rod 6 extends far away, the strip-shaped plate 7 reciprocally moves far away driven by the extension end of the electric push rod 6, so that the reciprocating swing range of the cooling pipe 4 is increased when spraying air.
