Description
Technical Field
[0001] Embodiments of the present disclosure relate to the technical field of overhead incoming line cabinets, and specifically, to an air-filled overhead incoming line cabinet for a generator set. Background Art
[0002] An air-filled overhead incoming line cabinet is an important device in the power system for connecting overhead lines with other electrical equipment. As the receiving end of the electrical energy of the overhead line, it introduces the electrical energy transmitted by the overhead line and then distributes it to the lower-level electrical equipment or busbars to achieve the orderly transmission and distribution of electrical energy. Through configured devices such as circuit breakers and disconnectors, the on-off control of the circuit can be carried out, and the circuit can be flexibly cut off or connected as needed to meet the requirements of the operation and maintenance of the power system. The air-filled overhead incoming line cabinet sets the cabinet shell as a cabinet with strong sealing performance, and sulfur hexafluoride gas is introduced into it as an insulating medium. Sulfur hexafluoride gas has excellent insulating performance and arc extinguishing ability, and can achieve insulation at a high voltage level in a relatively small space, thereby preventing short-circuit problems in the cabinet. The air-filled overhead incoming line cabinet is widely used in power stations, substations, urban distribution networks, and high-altitude and harsh environment areas.
[0003] In a power station, the generator set will integrate the currents of multiple generator sets by connecting to an air-filled overhead incoming line cabinet. When the generator set is operating, it will generate relatively large vibrations and heat. The incoming line cabinet will inevitably be affected by temperature and vibration due to its proximity to the generator set. However, since the air-filled overhead incoming line cabinet is filled with sulfur hexafluoride gas and the cabinet body maintains a high-sealing state, it is difficult for the internal equipment of the air-filled cabinet to dissipate heat effectively. At the same time, continuous vibration may cause the connection between the cable and the copper busbar on the incoming line cabinet to become loose, and loose connection may lead to line short-circuit or fire. Most of the existing incoming line cabinets have not been improved for the cabinet body in view of the use environment connected to the generator set, resulting in potential safety hazards for some incoming line cabinets connected to the generator set.

[0020] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.
[0021] Such as Figures 1 to 7As shown in the figure, it shows an inflatable overhead incoming line cabinet of a generator set in an embodiment of the present disclosure, which includes a mounting base 1, a connection switch device 2 and an external cabinet 3. The connection switch device 2 is fixedly installed on the mounting base 1, the external cabinet 3 is fixedly connected to the mounting base 1, and the external cabinet 3 is sleeved on the connection switch device 2. It also includes a sealed cabinet 4, a partition sealing mechanism, a connector 5 and a bottom shock absorption mechanism. The sealed cabinet 4 is sleeved on the connection switch device 2, the sealed cabinet 4 is arranged inside the external cabinet 3, an opening is provided at the top of the sealed cabinet 4, and the sealed cabinet 4 is detachably connected to the mounting base 1. The partition sealing mechanism is arranged on the external cabinet 3 and is detachably connected to the sealed cabinet 4. The partition sealing mechanism is used to seal the connection switch device 2 with the sealed cabinet 4. The connector 5 is fixedly arranged on the connection switch device 2, the connector 5 penetrates upward through the external cabinet 3 and the partition sealing mechanism, and a cable shock absorption mechanism is connected to the connector 5. The cable shock absorption mechanism is fixedly arranged on the top of the external cabinet 3 and is used to reduce the influence of the vibration of the cable on the connector 5. The mounting base 1 is arranged on the bottom shock absorption mechanism, and the bottom shock absorption mechanism is used to absorb the vibration of the external cabinet 3 and the mounting base 1. The internal part of the external cabinet 3 can be divided into two areas by the sealed cabinet 4 and the partition sealing mechanism. The space between the external cabinet 3 and the sealed cabinet 4 is sleeved with the sealed cabinet 4. At this time, heat insulation can be carried out through the sealed cabinet 4. The gas in the connection switch device 2 can be circulated and cooled through the gas circulation mechanism. In actual use, a cooling system such as an air conditioner will be set in the room where the incoming line cabinet is set to cool the incoming line cabinet as a whole.
[0022] As Figures 1 to 5As shown, the separation and sealing mechanism includes a driving cylinder 6, a sealing top cover 7 and a sealing groove 8. There are multiple driving cylinders 6, and the multiple driving cylinders 6 are fixedly arranged on the top of the external cabinet 3. The output end of the driving cylinder 6 is fixedly connected to the sealing top cover 7. The sealing top cover 7 is detachably connected to the top of the sealed cabinet 4. The sealing groove 8 is opened on the mounting base 1, and the sealing groove 8 is detachably connected to the sealed cabinet 4. An elastic channel 15 is sleeved on the connecting head 5. One end of the elastic channel 15 is connected to the sealing top cover 7, and the other end is connected to the external cabinet 3. A sealing rubber strip is arranged on the edge of the sealing top cover 7. When the output end of the driving cylinder 6 pushes the sealing top cover 7 to press down on the sealed cabinet 4, the sealing strip 9 enters the sealing groove 8, and the sealing top cover 7 fits with the top of the sealed cabinet 4, so that the inside of the sealed cabinet 4 is sealed. At this time, through the isolation of the sealed cabinet 4, the influence on the connection switch device 2 from the outside can be reduced. When the temperature inside the connection switch device 2 rises, the output end of the driving cylinder 6 can be shortened to pull the sealing top cover 7 to move upward. The sealing top cover 7 pulls the sealed cabinet 4 to move upward through the lifting frame 10. A vertical frame is arranged on the mounting base 1, and the sealed cabinet 4 slides along the vertical frame. The sealing strip 9 is separated from the sealing groove 8. At this time, the gas circulation mechanism can circulate the gas inside the sealed cabinet 4 for heat dissipation.
[0023] As Figures 1 to 5 shown, a sealing strip 9 and a lifting frame 10 are arranged on the sealed cabinet 4. The sealing strip 9 is fixedly connected to the bottom of the sealed cabinet 4, and the sealing strip 9 is detachably connected to the sealing groove 8. The lifting frame 10 is fixedly connected to the edge of the sealed cabinet 4. When the sealing top cover 7 moves upward, it contacts the lifting frame 10. When the sealing top cover 7 moves upward, the sealing top cover 7 contacts the lifting frame 10 and drives the sealed cabinet 4 to move upward. Through holes are opened on the side of the lifting frame 10. After the sealing top cover 7 lifts the sealed cabinet 4 upward, three-dimensional circulation can be carried out on both the top and the bottom of the sealed cabinet 4, so as to ventilate and cool the internal connection switch device 2.
[0024] As Figure 3 and Figure 7As shown in the figure, a plurality of gas circulation mechanisms are provided on the side of the external cabinet 3. The gas circulation mechanism includes a diversion chamber 11, a fan 12, a suction channel 13, and an exhaust channel 14. The diversion chamber 11 is opened on the side of the external cabinet 3. The fan 12 is fixedly installed on the external cabinet 3. The blades on the fan 12 are arranged in the diversion chamber 11. The suction channel 13 is fixedly connected to the diversion chamber 11. The area of the diversion chamber 11 at the central position of the blades is communicated with the suction channel 13. The exhaust channel 14 is opened on the side of the diversion chamber 11. The exhaust channel 14 faces upward, and the suction channel 13 faces downward. When the blades rotate, the gas between the external cabinet 3 and the sealed cabinet 4 is sucked into the diversion chamber 11 through the suction channel 13 and discharged upward through the exhaust channel. Since the density of sulfur hexafluoride gas is greater than that of air, the sulfur hexafluoride gas will accumulate inside the cabinet and move downward, sucking the gas flowing out between the sealing groove 8 and the sealing strip 9 and discharging it upward, and then entering the sealed cabinet 4 through the gap between the lifting frames 10, so as to realize the circulating flow of gas inside the incoming line cabinet. When the temperature of the connection switch device 2 is relatively high, in order to cool the incoming line cabinet, refrigeration equipment such as an air conditioner will be installed in the room where the incoming line cabinet is set. The refrigeration equipment will reduce the temperature of the external cabinet 3. Through the gas circulation in the sealed cabinet 4, the gas contacts the external cabinet 3 and cools down and then flows back into the sealed cabinet 4. And through the way of sucking from the bottom and discharging upward, the sulfur hexafluoride gas can be fully cooled when passing through the connection switch device 2 during the downward movement process.
[0025] As Figures 1 to 4 shown in the figure, the cable shock absorption mechanism includes a cable 16, a limit plate 17, and a spiral slideway 18. The cable 16 is connected to the connector 5. The limit plate 17 is fixedly connected to the top of the external cabinet 3. The cable 16 passes through the limit plate 17. The spiral slideway 18 is fixedly connected to the top of the external cabinet 3. The cable 16 is arranged on the spiral slideway 18. The cable 16 is placed on the spiral slideway 18. There is a gap between the edge of the spiral slideway 18 and the cable 16. When the cable 16 is vibrated, the cable 16 can slide on the spiral slideway 18 in the vibration direction, so that the cable 16 can absorb the shock in multiple directions. At the same time, by fixing the cable 16 through the limit plate 17, the vibration transmitted by the cable 16 to the connector 5 can be reduced.
[0026] As Figures 1 to 2As shown in the figure, the bottom shock absorption mechanism includes a shock absorption pad 19 and a shock absorption frame 20. The shock absorption pad 19 is arranged at the bottom of the mounting seat 1, and the shock absorption frame 20 is sleeved on the outer cabinet 3. A plurality of spring plates 21 are fixedly connected to the shock absorption frame 20. The spring plates 21 are arranged in an arc shape and are in contact with the outer cabinet 3. Through the spring plates 21, the vibration of the outer cabinet 3 in the horizontal direction can be supported and absorbed. Through the shock absorption pad 19, the longitudinal vibration can be absorbed, preventing the connection switch device 2 and the connector 5 from being subjected to large vibrations. The vibration may cause the connection joints to be unstable, resulting in disconnection or short circuit.
[0027] The working principle of the inflatable overhead incoming line cabinet of this generator set is as follows: When the incoming line cabinet is vibrated, the shock absorption pad 19 and the spring plates 21 absorb the vibration of the outer cabinet 3. The cable 16 bends and slides along the spiral chute 18 in multiple vibration directions, reducing the vibration transmitted to the connector 5. At present, some incoming line cabinets are provided with ventilation holes, and a sealing device or a filtering device is arranged at the ventilation holes to reduce the outflow of sulfur hexafluoride gas. However, it cannot be guaranteed that there is no outflow of sulfur hexafluoride gas. At the same time, since the gas entering from the outside has a different density from the sulfur hexafluoride gas, there may be a problem of uneven heat dissipation. Therefore, there is no ventilation opening provided on the cabinet in this invention. When the temperature outside the outer cabinet 3 is relatively high, the output end of the driving cylinder 6 extends to push the sealing top cover 7 downward. The sealing top cover 7 contacts the sealed cabinet 4 and seals the top of the sealed cabinet 4. The sealing strip 9 enters the sealing groove 8, and the connection switch device 2 is insulated by the sealed cabinet 4 and the outer cabinet 3. When the temperature of the connection switch device 2 is relatively high, the output end of the driving cylinder 6 shortens to pull the sealing top cover 7 upward. The sealed cabinet 4 is lifted upward through the lifting frame 10. The fan 12 is started, and the gas in the sealed cabinet 4 is sucked from the bottom into the diversion chamber 11 through the suction channel 13 and sprayed upward through the exhaust channel 14. The gas flows into the sealed cabinet 4 at the lifting frame 10 for gas circulation.
[0028] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not restrictive. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered within the scope of the claims of the present disclosure.
