Description

Technical Field

[0001] The present invention relates to the technical field of busbar anti-condensation, and in particular to a closed busbar anti-condensation device and a use method thereof. Background Art

[0002] The closed busbar is mainly used to transmit electrical energy and has the ability to collect and distribute electricity.

[0003] In the distribution cabinet, if there is a large temperature difference between the inside of the closed busbar and the inside of the distribution cabinet, and the humidity inside the distribution cabinet is high, condensation will easily occur on the closed busbar, leading to safety hazards such as short circuit and degradation of insulation performance.

[0004] In the distribution cabinet, if a component short-circuits due to aging or failure, this will cause a sharp increase in current in the circuit. Although the power supply voltage remains unchanged, the increased current will cause the enclosed busbar and other conductive parts to heat up rapidly. Although the circuit breaker should respond immediately and cut off the power supply to prevent further damage, the heat that has been generated will still remain in the enclosed busbar for a period of time and will be difficult to dissipate quickly. This high temperature exposure may damage the enclosed busbar, reduce its service life, and may cause other safety hazards.

[0005] At the same time, since the closed busbar usually accommodates multiple busbars side by side, when the above-mentioned overload situation occurs, the busbar in the middle is more difficult to dissipate heat than the busbars on the sides, causing the busbar in the middle to be more easily damaged, affecting the service life of the busbars in the above-mentioned positions.

DETAILED DESCRIPTION

[0031] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0032] Example 1

[0033] like Figure 1-Figure 9 As shown, a closed busbar anti-condensation device includes a distribution cabinet 1; a temperature sensor 1 is arranged in the distribution cabinet 1;

[0034] It also includes an upper limit plate 3, a lower limit plate 4, a first drive member 5, a second drive member 6, a clamping plate 7, a fitting plate 8, a limit rod 9 and a heat dissipation component; two left-right symmetrical first drive members 5 are connected in the power distribution cabinet 1, and the first drive member 5 is an electric push rod; the telescopic ends of the two first drive members 5 are commonly connected to the upper limit plate 3, and the upper limit plate 3 is set as a hollow structure; a temperature sensor 2 is set on the upper limit plate 3; a plurality of clamping plates 7 arranged in a rectangular array are connected to the upper limit plate 3, each clamping plate 7 is set as a hollow structure, and the upper limit plate 3 is connected to all the clamping plates 7 The power distribution cabinet 1 is connected with a second driving member 6, which is an electric push rod; the telescopic end of the second driving member 6 is connected with a lower limit plate 4, which is a hollow structure; the lower limit plate 4 is connected with a plurality of interlocking plates 8, which are hollow structures and are connected with the lower limit plate 4; each interlocking plate 8 corresponds to an adjacent clamping plate 7 one by one; each interlocking plate 8 can be embedded in an adjacent clamping plate 7; each interlocking plate 8 is connected with two left-right symmetrical limit rods 9; the power distribution cabinet 1 is connected with a heat dissipation component.

[0035] The heat dissipation component includes a fan 101, a guide 102, a first turning block 103, a first bellows 104, a second bellows 106, a second turning block 107 and an air outlet pipe 108; the fan 101 is fixedly connected to the inner rear of the distribution cabinet 1; the guide 102 is fixedly connected to the inner rear of the distribution cabinet 1; the front side of the guide 102 is connected to the first turning block 103; the lower side of the first turning block 103 is connected to the first bellows 104; the other end of the first bellows 104 is connected to the upper limit plate 3; the lower right part of the lower limit plate 4 is connected to the second bellows 106; the lower side of the second bellows 106 is connected to the second turning block 107; the right side of the second turning block 107 is connected to the air outlet pipe 108; the other end of the air outlet pipe 108 is connected to the outside of the distribution cabinet 1.

[0036] It also includes an electric heating ring 105 ; the electric heating ring 105 is fixedly connected to the upper inner portion of the first bellows 104 .

[0037] A plurality of heat sinks are provided on the opposite sides of the clamping plates 7 located at the frontmost side and the rearmost side.

[0038] First, when the components in the distribution cabinet 1 are in normal use, the busbar 2 is heated by the passage of current, so that the upper limit plate 3, the lower limit plate 4 and the clamping plate 7 that are close to the busbar 2 are heated up due to the heating of the busbar 2. At this time, the fan 101 is used to blow air into the distribution cabinet 1, so that the airflow enters the first turning block 103 along the guide 102, and then enters the first bellows 104. Then, the airflow enters the upper limit plate 3 through the first bellows 104, passes through the clamping plate 7, and then enters the air outlet pipe 108 through the second bellows 106 and the second turning block 107 connected to the lower limit plate 4, and then flows to the outside of the distribution cabinet 1, so that the airflow blown out by the fan 101 takes away the heat on the upper limit plate 3, the lower limit plate 4 and the clamping plate 7, and transfers the heat to the outside of the distribution cabinet 1, so as to achieve the heat dissipation of the upper limit plate 3, the lower limit plate 4 and the clamping plate 7. Heat is then exchanged with the busbar 2 through the upper limit plate 3, the lower limit plate 4 and the clamping plate 7, thereby realizing the heat dissipation of the busbar 2, avoiding the temperature difference between the surface of the busbar 2 and the inside of the distribution cabinet 1, which causes condensation on the busbar 2. At the same time, when the temperature sensed by the temperature sensor 1 is higher than the temperature sensed by the temperature sensor 2, that is, the temperature in the distribution cabinet 1 is higher than the temperature of the busbar 2, and when the temperature in the distribution cabinet 1 is not higher than the normal working temperature of the busbar 2, the airflow blowing to the upper limit plate 3, the lower limit plate 4 and the clamping plate 7 is adaptively heated by the electric heating ring 105, so that the hot air flow heats the surface of the busbar 2, so that the position where the busbar 2 is wrapped maintains the same temperature as that in the distribution cabinet 1, to prevent the temperature of the position where the busbar 2 is wrapped from dropping when the humidity in the distribution cabinet 1 is high, resulting in condensation at the position where the busbar 2 is wrapped.

[0039] Subsequently, when the components in the distribution cabinet 1 are overloaded, the temperature of the busbar 2 further rises due to the overload of the components. At this time, the temperature of the busbar 2 is sensed by the second temperature sensor on the upper limit plate 3. When the temperature of the busbar 2 exceeds the threshold, the first driving member 5 is controlled by the second temperature sensor to drive the upper limit plate 3 to move upward, thereby driving the clamping plate 7 to move upward, and causing the first bellows 104 to shrink upward, so that the clamping plate 7 is gradually separated from the interlocking plate 8 and the limiting rod 9. It is worth noting that at this time, the busbar 2 is fixedly connected to the components in the distribution cabinet 1. Therefore, the busbar 2 will not move, and when the clamping plate 7 moves to the position as shown in the figure, the busbar 2 will not move. Figure 6 In the state shown, the upper limit plate 3 and the clamping plate 7 are controlled to stop moving upward. At this time, the front side, upper side and rear side of the busbar 2 are exposed. At the same time, the second driving member 6 is controlled to drive the lower limit plate 4, the interlocking plate 8 and the limit rod 9 to move downward, so that the second bellows 106 is compressed downward, so that the lower limit plate 4 is no longer in contact with the lower side of the busbar 2, so that the position of the busbar 2 originally wrapped by the upper limit plate 3, the lower limit plate 4 and the clamping plate 7 is completely exposed to the air in the distribution cabinet 1. At this time, since the lower side opening of the clamping plate 7 is separated from the interlocking plate 8, the fan 101 continues to blow air, so that the airflow is blown downward along the clamping plate 7. Since the lower end of the clamping plate 7 is located on the upper side of the busbar 2 at this time and is completely separated from the busbar 2, the airflow blown out from the clamping plate 7 will directly blow toward the busbar 2. The exposed part allows the air flow to take away the heat generated by the busbar 2 due to the overload of components, thereby achieving heat dissipation for the entire busbar 2, further improving the heat dissipation effect of the busbar 2, and avoiding overload of components in the distribution cabinet 1, which leads to excessive temperature of the busbar 2, damage to the busbar 2, and affecting the service life of the busbar 2. Compared with the prior art, the present invention realizes direct blowing of air to the position where the busbar 2 is wrapped by the upper limit plate 3, the lower limit plate 4 and the clamping plate 7 under overload conditions, so that the wind blows to the entire busbar 2, thereby achieving heat dissipation for the entire busbar 2, and avoiding further increase in the temperature of the busbar 2 due to the overload of components. At this time, the busbar 2 is always wrapped and protected by the upper limit plate 3, the lower limit plate 4 and the clamping plate 7, and it is difficult to dissipate heat comprehensively, resulting in damage to the busbar 2 and affecting the service life of the busbar 2.

[0040] Subsequently, when the components in the distribution cabinet 1 resume normal operation and the temperature on the busbar 2 drops below the second threshold of the temperature sensor, the first driving member 5 is controlled to drive the upper limit plate 3 and the clamping plate 7 to move downward to reset, so that the first bellows 104 gradually stretches downward, and the second driving member 6 is controlled to drive the lower limit plate 4, the interlocking plate 8 and the limit rod 9 to move upward to reset, so that the second bellows 106 stretches upward, so that the interlocking plate 8 and the limit rod 9 are re-embedded in the clamping plate 7, so that the busbar 2 is re-wrapped by the upper limit plate 3, the lower limit plate 4 and the clamping plate 7, so that the upper limit plate 3, the lower limit plate 4 and the clamping plate 7 can protect the busbar 2 again.

[0041] Through the above contents, the busbar 2 can be completely enclosed for protection and the heat dissipation of the busbar 2 can be enhanced respectively, and the two states can be flexibly switched according to the working state of the components in the distribution cabinet 1 and the real-time monitoring of the temperature of the busbar 2 by the second temperature sensor, so the device has stronger applicability.

[0042] The rear side of the guide 102 is flared, so that the airflow is accelerated when passing through the guide 102 , thereby improving the heat dissipation effect of the airflow on the busbar 2 .

[0043] The distribution cabinet 1 is provided with a plurality of symmetrical heat dissipation holes, and the heat dissipation holes are located directly opposite to the busbar 2; the airflow passing through the heat dissipation holes and blowing into the distribution cabinet 1 generates convection at the upper limit plate 3, the lower limit plate 4 and the clamping plate 7, further improving the heat dissipation effect on the busbar 2.

[0044] Example 2

[0045] On the basis of Example 1, Figure 2-Figure 4 As shown, a cleaning component is also included, which includes a cleaner 201, an extrusion rod 202 and a collection box 203; a cleaner 201 is fixedly connected to the upper side of every two corresponding limit rods 9 on the left and right, and the cleaner 201 is made of rubber; the edge of the cleaner 201 fits with the inner side of the clamping plate 7; an extrusion rod 202 is fixedly connected to the inner rear part of the distribution cabinet 1; the extrusion rod 202 is located at the lower right part of the lower limit plate 4; a collection box 203 is fixedly connected to the inner rear part of the distribution cabinet 1; the collection box 203 is located at the lower left part of the lower limit plate 4.

[0046] Since the outside air will bring in fine dust and impurities, the dust and impurities are easy to adhere to the inner side of the clamping plate 7. Over time, it is easy to cause the channel inside the clamping plate 7 to be blocked, reducing the heat dissipation effect on the busbar 2. Therefore, in the process of the upper limit plate 3 moving upward, the lower limit plate 4 moves downward, causing the clamping plate 7 to gradually separate from the interlocking plate 8, the limit rod 9 and the cleaner 201. Since the edge of the cleaner 201 is in contact with the inner side of the clamping plate 7, the edge of the cleaner 201 will scratch the inside of the clamping plate 7, so that the impurities adhered to the inside of the clamping plate 7 are scraped off by the cleaner 201, thereby cleaning the impurities adhered to the inside of the clamping plate 7, preventing impurities from adhering to the inside of the clamping plate 7, clogging the clamping plate 7, and affecting the ventilation of the clamping plate 7. Subsequently, the impurities scraped off by the cleaner 201 will move downward. The impurities may fall onto the lower limit plate 4 or fall into the inner side of the lower limit plate 4 through the interlocking plate 8. The impurities that fall into the inner side of the lower limit plate 4 will flow out of the distribution cabinet 1 from the air outlet pipe 108 as the busbar 2 is subsequently cooled down. As for the impurities that fall on the lower limit plate 4, when the second driving member 6 drives the lower limit plate 4 to continue to move downward, the second corrugated tube 106 will be deformed, and the right side of the lower limit plate 4 will be blocked by the extrusion rod 202. Based on the view from front to back, the lower limit plate 4 will rotate counterclockwise, so that the left side of the lower limit plate 4 becomes downwardly inclined, and the impurities on the lower limit plate 4 fall to the left along the lower limit plate 4 into the collection box 203, and then the collection box 203 will be pulled out by regular maintenance personnel to clean the impurities in the collection box 203.

[0047] Based on the above work, the first driving member 5 and the second driving member 6 can also be set to be started regularly to drive the upper limit plate 3 and the lower limit plate 4 to separate and move, so as to achieve regular cleaning of the inside of the clamping plate 7.

[0048] Each cleaner 201 is arranged in an inverted trapezoidal shape, and produces a shoveling effect on the impurities adhered in the clamping plate 7, thereby improving the cleaning effect of the impurities in the clamping plate 7.

[0049] The upper side of the collecting box 203 is flared to facilitate guiding the impurities on the lower limiting plate 4 to fall into the collecting box 203 .
