A closed busbar anti-condensation device and its usage method

Abstract

This invention relates to the field of busbar anti-condensation technology, and more particularly to a closed busbar anti-condensation device and its usage method. The closed busbar anti-condensation device includes a distribution cabinet and first driving components, etc.; two first driving components are connected inside the distribution cabinet. This invention achieves this by directing the airflow from the clamping plate directly onto the exposed part of the busbar, allowing the airflow to carry away the heat generated by the busbar due to component overload, further achieving heat dissipation of the busbar. This prevents overload of components inside the distribution cabinet, which could lead to excessively high busbar temperatures, damage, and reduced busbar lifespan. The heating ring heats the airflow blowing towards the upper limit plate, lower limit plate, and clamping plate, causing the hot airflow to heat the busbar surface, maintaining the temperature of the enclosed part of the busbar at the same level as inside the distribution cabinet. This prevents condensation from occurring at the enclosed part of the busbar when the humidity inside the distribution cabinet is high, as this would cause the temperature to drop.

Description

Technical Field

[0001] This invention relates to the field of busbar anti-condensation technology, and in particular to a closed busbar anti-condensation device and its usage method. Background Technology

[0002] Enclosed busbars are mainly used for transmitting electrical energy and have the ability to collect and distribute power.

[0003] If there is a large temperature difference between the inside of the enclosed busbar and the inside of the distribution cabinet, and the humidity inside the distribution cabinet is high, condensation is very likely to occur on the enclosed busbar, leading to safety hazards such as short circuits and reduced insulation performance.

[0004] Inside the distribution cabinet, if a component short-circuits due to aging or failure, the current in the circuit will increase sharply. 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 already generated will 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] Meanwhile, since enclosed busbars typically house multiple busbars side by side, when the aforementioned overload occurs, the busbar in the middle is more difficult to dissipate heat than the busbars on the sides, making the busbar in the middle more susceptible to damage and affecting the service life of the busbars in the aforementioned positions. Summary of the Invention

[0006] To overcome the shortcomings of enclosed busbars that are difficult to cool down quickly in a short time due to component overload, which leads to damage to the enclosed busbars due to high temperature and reduces the service life of the enclosed busbars, this invention provides an anti-condensation device for enclosed busbars and its usage method.

[0010] Preferably, several heat sinks are provided on the opposite sides of the clamping plates located at the front and rear sides.

[0011] Preferably, the rear side of the guide is flared.

[0012] As a preferred option, the distribution cabinet has several heat dissipation holes, and the heat dissipation holes are positioned directly opposite the busbar.

[0013] Preferably, a cleaning assembly is also included, comprising a cleaner, a squeezing rod, and a collection box; a cleaner for cleaning impurities adhering to the inner side of the clamping plate is fixedly connected to the upper side of each pair of left and right corresponding limit rods, the cleaner being made of rubber; the edge of the cleaner is in contact with the inner side of the clamping plate; a squeezing rod is fixedly connected to the inner side of the distribution cabinet; the squeezing rod is located below the lower limit plate; a collection box for collecting impurities on the upper surface of the lower limit plate is fixedly connected to the inner side of the distribution cabinet; the collection box is located below the lower limit plate.

Detailed Implementation

[0031] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0032] Example 1

[0033] like Figures 1-9 As shown, a closed busbar anti-condensation device includes a distribution cabinet 1; a temperature sensor is installed inside the distribution cabinet 1.

[0034] It also includes an upper limit plate 3, a lower limit plate 4, a first drive component 5, a second drive component 6, a clamping plate 7, a fitting plate 8, a limit rod 9, and a heat dissipation assembly; the distribution cabinet 1 is connected to two symmetrical first drive components 5, which are electric push rods; the telescopic ends of the two first drive components 5 are connected to the upper limit plate 3, which is a hollow structure; a temperature sensor 2 is installed on the upper limit plate 3; several clamping plates 7 arranged in a rectangular array are connected to the upper limit plate 3, each clamping plate 7 is a hollow structure, and the upper limit plate 3 is connected to all the clamping plates 7. Each busbar 2 is located between two adjacent clamping plates 7; a second driving component 6 is connected inside the distribution cabinet 1, which is an electric push rod; the telescopic end of the second driving component 6 is connected to a lower limit plate 4, which is a hollow structure; several fitting plates 8 are connected to the lower limit plate 4, which is a hollow structure and communicates with the lower limit plate 4; each fitting plate 8 corresponds one-to-one with an adjacent clamping plate 7; each fitting plate 8 can be embedded in an adjacent clamping plate 7; two left-right symmetrical limit rods 9 are connected to each fitting plate 8; a heat dissipation component is connected inside the distribution cabinet 1.

[0035] The heat dissipation assembly includes a fan 101, a guide 102, a first deflector block 103, a first corrugated pipe 104, a second corrugated pipe 106, a second deflector block 107, and an exhaust pipe 108. The fan 101 is fixedly connected to the rear inner side of the distribution cabinet 1. The guide 102 is fixedly connected to the rear inner side of the distribution cabinet 1. The first deflector block 103 is connected to the front side of the guide 102. The first corrugated pipe 104 is connected to the lower side of the first deflector block 103. The other end of the first corrugated pipe 104 is connected to the upper limit plate 3. The second corrugated pipe 106 is connected to the lower right side of the lower limit plate 4. The second deflector block 107 is connected to the lower side of the second corrugated pipe 106. The exhaust pipe 108 is connected to the right side of the second deflector block 107. The other end of the exhaust 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 side of the first corrugated pipe 104.

[0037] Several heat sinks are provided on the opposite sides of the clamping plates 7 located at the front and rear sides.

[0038] First, when the components inside the distribution cabinet 1 are in normal use, the busbar 2 heats up due to the current flowing through it. This causes the upper limit plate 3, lower limit plate 4, and clamping plate 7, which are in close contact with the busbar 2, to heat up as well. At this time, the fan 101 blows air into the distribution cabinet 1, causing the airflow to enter the first deflector block 103 along the guide 102, then enter the first corrugated pipe 104, and then the airflow enters the upper limit plate 3 through the first corrugated pipe 104, then passes through the clamping plate 7, and then enters the exhaust pipe 108 through the second corrugated pipe 106 and the second deflector block 107 connected to the lower limit plate 4. Finally, the airflow flows out of the distribution cabinet 1, thus carrying away the heat from the upper limit plate 3, lower limit plate 4, and clamping plate 7, transferring the heat to the outside of the distribution cabinet 1, thereby achieving heat dissipation from the upper limit plate 3, lower limit plate 4, and clamping plate 7. Heat is transferred to the busbar 2 via the upper limit plate 3, lower limit plate 4, and clamping plate 7, thereby achieving heat dissipation of the busbar 2 and preventing condensation on the busbar 2 due to a temperature difference between the surface of the busbar 2 and the interior of the distribution cabinet 1. Simultaneously, when the temperature sensed by temperature sensor 1 is higher than that sensed by temperature sensor 2 (i.e., the temperature inside the distribution cabinet 1 is higher than the temperature of the busbar 2), and when the temperature inside the distribution cabinet 1 is not higher than the normal operating temperature of the busbar 2, the airflow blown towards the upper limit plate 3, lower limit plate 4, and clamping plate 7 is adaptively heated by the heating ring 105. This heats the surface of the busbar 2, keeping the area where the busbar 2 is wrapped at the same temperature as inside the distribution cabinet 1. This prevents condensation from forming at the wrapped area of ​​the busbar 2 when the humidity inside the distribution cabinet 1 is high.

[0039] Subsequently, when the components in the distribution cabinet 1 are overloaded, the temperature of busbar 2 rises further due to the overload. At this time, the temperature sensor on the upper limit plate 3 senses the temperature of busbar 2. When the temperature of busbar 2 exceeds the threshold, the temperature sensor controls the first driving component 5 to move the upper limit plate 3 upward, thereby moving the clamping plate 7 upward and causing the first corrugated pipe 104 to retract upward, so that the clamping plate 7 gradually separates from the fitting plate 8 and the limiting rod 9. It is worth noting that at this time, busbar 2 is fixedly connected to the components in the distribution cabinet 1, so busbar 2 will not move, but the clamping plate 7 moves to the position where... Figure 6 In the indicated state, the upper limit plate 3 and clamping plate 7 stop moving upwards. At this time, the front, upper, and rear sides of busbar 2 are exposed. Simultaneously, the second driving component 6 drives the lower limit plate 4, fitting plate 8, and limit rod 9 downwards, causing the second bellows 106 to compress downwards. This prevents the lower limit plate 4 from contacting the lower side of busbar 2, thus exposing the area of ​​busbar 2 previously covered by the upper limit plate 3, lower limit plate 4, and clamping plate 7 to the air inside the distribution cabinet 1. At this time, since the lower opening of clamping plate 7 separates from fitting plate 8, fan 101 continues to blow air, causing the airflow to blow downwards along clamping plate 7. Since the lower end of clamping plate 7 is located above busbar 2 and completely detached from busbar 2, the airflow from clamping plate 7 will directly blow onto busbar 2. The exposed portion allows airflow to carry away the heat generated by the overload of components in busbar 2, thereby achieving heat dissipation for the entire busbar 2 and further improving the heat dissipation effect of busbar 2. This avoids the overload of components in the distribution cabinet 1, which could lead to excessively high temperatures in busbar 2, causing damage to busbar 2 and affecting its service life. Compared with the prior art, this invention achieves direct airflow to the portion of busbar 2 covered by the upper limit plate 3, lower limit plate 4, and clamping plate 7 under overload conditions, directing the airflow to the entire busbar 2 and achieving heat dissipation for the entire busbar 2. This prevents the temperature of busbar 2 from further increasing due to component overload. However, under these conditions, busbar 2 is always covered and protected by the upper limit plate 3, lower limit plate 4, and clamping plate 7, making it difficult to dissipate heat comprehensively, which could lead to damage to busbar 2 and affect its service life.

[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 component 5 is controlled to move the upper limit plate 3 and the clamping plate 7 downwards to reset, causing the first corrugated pipe 104 to gradually stretch downwards. The second driving component 6 is then controlled to move the lower limit plate 4, the fitting plate 8, and the limit rod 9 upwards to reset, causing the second corrugated pipe 106 to stretch upwards. This allows the fitting plate 8 and the limit rod 9 to re-embed into the clamping plate 7, thereby allowing the busbar 2 to be wrapped again by the upper limit plate 3, the lower limit plate 4, and the clamping plate 7, thus enabling the upper limit plate 3, the lower limit plate 4, and the clamping plate 7 to once again protect the busbar 2.

[0041] Through the above, complete enclosure protection of busbar 2 and enhanced heat dissipation of busbar 2 can be achieved respectively. The two states can be flexibly switched according to the working status of the components in the distribution cabinet 1 and the real-time monitoring of the temperature of busbar 2 by temperature sensor 2, making the device more versatile.

[0042] The rear side of the guide 102 is flared, which increases the speed of the airflow when it passes through the guide 102 and improves the heat dissipation effect of the airflow on the bus 2.

[0043] The distribution cabinet 1 has several symmetrical heat dissipation holes, and the heat dissipation holes are positioned directly opposite the busbar 2; this allows the airflow blowing into the distribution cabinet 1 through the heat dissipation holes to generate 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] Based on Example 1, such as Figures 2-4 As shown, it also includes a cleaning assembly, which includes a cleaner 201, a squeezing rod 202, and a collection box 203; a cleaner 201 is fixedly attached to the upper side of each pair of left and right corresponding limit rods 9, and the cleaner 201 is made of rubber; the edge of the cleaner 201 is attached to the inner side of the clamping plate 7; a squeezing rod 202 is fixedly attached to the rear inner side of the distribution cabinet 1; the squeezing rod 202 is located on the lower right side of the lower limit plate 4; a collection box 203 is fixedly attached to the rear inner side of the distribution cabinet 1; the collection box 203 is located on the lower left side of the lower limit plate 4.

[0046] Because fine dust and impurities can be carried in by the outside air, these particles easily adhere to the inside of the clamping plate 7. Over time, this can clog the channels inside the clamping plate 7, reducing the heat dissipation effect on the busbar 2. Therefore, as the upper limit plate 3 moves upward, the lower limit plate 4 moves downward, causing the clamping plate 7 to gradually detach from the mating plate 8, the limit rod 9, and the cleaner 201. Since the edge of the cleaner 201 is in contact with the inside of the clamping plate 7, the edge of the cleaner 201 will scrape against the inside of the clamping plate 7, causing the impurities adhering to the inside of the clamping plate 7 to be scraped off. This cleans the impurities adhering to the inside of the clamping plate 7, preventing them from adhering to the inside of the clamping plate 7, clogging the clamping plate 7, and affecting its ventilation. Subsequently, the impurities scraped off by the cleaner 201 will move downward. Impurities falling onto the lower limit plate 4, or falling into the inner side of the lower limit plate 4 through the interlocking plate 8, will flow out of the distribution cabinet 1 through the air outlet pipe 108 when the fan 101 blows air during the subsequent cooling of the busbar 2. As for the impurities falling onto the lower limit plate 4, when the second drive component 6 drives the lower limit plate 4 to move downward continuously, the second corrugated pipe 106 will deform, and the right side of the lower limit plate 4 will be blocked by the extrusion rod 202. Based on the front-to-back view, the lower limit plate 4 will rotate counterclockwise, causing the left side of the lower limit plate 4 to tilt downward, thereby causing the impurities on the lower limit plate 4 to fall to the left along the lower limit plate 4 into the collection box 203. Then, the collection box 203 will be pulled out by the regular maintenance personnel to clean the impurities inside the collection box 203.

[0047] Based on the above work, it is also possible to set the first driving component 5 and the second driving component 6 to be activated periodically to drive the upper limit plate 3 and the lower limit plate 4 to separate and move, thereby realizing the periodic cleaning of the inside of the clamping plate 7.

[0048] Each cleaner 201 is arranged in an inverted trapezoidal shape; it has a scooping effect on the impurities adhering to the clamping plate 7, thereby improving the cleaning effect on the impurities in the clamping plate 7.

[0049] The upper side of the collection box 203 is flared to facilitate the guidance of impurities on the lower limit plate 4 into the collection box 203.

[0050] A method of using a closed busbar anti-condensation device includes the following:

[0051] S1: Heat dissipation. When the components in the distribution cabinet 1 are operating normally, the fan 101 is controlled to blow air to dissipate heat from the busbar 2.

[0052] S2: Emergency heat dissipation. When the components in the distribution cabinet 1 are overloaded, the upper limit plate 3 and the clamping plate 7 are moved upward by controlling the upper limit plate 3 and the clamping plate 7, while the lower limit plate 4, the fitting plate 8 and the limit rod 9 are moved downward, so that the position of the busbar 2 that was originally covered 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, thereby enhancing the heat dissipation effect on the busbar 2.

[0053] S3: Temperature balance, the air blown out by the fan 101 is heated by the electric heating ring 105 to raise the temperature of the busbar 2 so that the temperature of the busbar 2 is the same as the temperature inside the distribution cabinet 1.

[0054] S4: Impurity removal, by moving the clamping plate 7 and the cleaner 201 out of position, the cleaner 201 scrapes off the impurities inside the clamping plate 7.

[0055] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
