DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0033] The adapter terminal for connecting cables on the upper side of the existing ring main unit faces upward, which means that the cables between two adjacent ring main units need to be bent upward when connected, which results in a waste of cable line length and increases the cost of installing the ring main unit.

[0034] In addition, the transfer terminal of the existing ring network cabinet faces upward, which easily causes water droplets and moisture to accumulate in the transfer terminal, thereby causing a short circuit at the cable end and even causing electric shock to personnel.

[0035] Example 1: A new type of intelligent power distribution ring main unit, Figure 1-Figure 5As shown, it includes a shell 1 distributed in a straight line. In actual use, the number of shells 1 needs to be adjusted according to the composition of the ring network cabinet. In the figure, only two shells 1 are used for illustration. An intelligent power distribution terminal unit is arranged in the shell 1. The shell 1 is installed with a control panel 2. The control panel 2 is electrically connected to the intelligent power distribution terminal unit. The two shells 1 are connected through three connectors 3 distributed in a straight line array. The connector 3 is detachably connected to the adjacent shell 1. When docking two adjacent shells 1, lubricate both ends of the connector 3, and then insert the left and right ends of the connector 3 into the two outer shells 1 respectively. The shell 1 has a voltage sensor 4 which is electrically connected to the adjacent control panel 2 installed in it. The voltage sensor 4 is an electronic voltage sensor with high efficiency and integration, and the voltage sensor 4 has an isolation voltage module built in it. The upper side of the shell 1 is fixedly connected with a fixing plate 5 which is symmetrically distributed front and back. The opposite sides of the symmetrically distributed fixing plates 5 are slidably connected with a clamping plate 6. The clamping plate 6 is provided with vertically arranged clamping grooves. The number of the clamping grooves on the clamping plate 6 is consistent with the number of the adapter 7 on the adjacent shell 1. An elastic member is fixedly connected between the clamping plate 6 and the adjacent fixing plate 5, wherein the elastic member is a compression spring. After the cable is placed between the two clamping plates 6, The elastic part of the clamping plate 6 is compressed and stored, and a straight-line adapter 7 is fixedly connected to the upper side of the housing 1, which is used to convert the vertical cable connection port of the housing 1 into a horizontal port. The height of the straight-line adapter 7 decreases from left to right. The adapters 7 of the same height on different housings 1 are connected by cables to make the height positions of the wires of different ports different. The two clamping plates 6 clamp the cables to reduce the possibility of contact and entanglement between the cables, so as to facilitate line replacement and maintenance. The upper side of the housing 1 is slidably connected to the adjacent control panel 2 through an electromagnetic slide rail. An electromagnetic slider 8 is fixedly connected to a cover 9 on the upper side of the electromagnetic slider 8. The cover 9 is used to shield the adapters 7 that are distributed in adjacent straight lines, thereby reducing the probability of water droplets in the external environment falling onto the adapters 7. A carrier box 10 is fixedly connected to the upper side of the housing 1 near the adapters 7 that are distributed in adjacent straight lines. A rotating shell 11 for loading a granular desiccant is rotatably connected inside the carrier box 10. When installing the device, the desiccant is placed in the rotating shell 11. Air holes are provided on the upper and lower sides of the rotating shell 11 to allow the desiccant in the rotating shell 11 to contact with moisture in the external air.

[0036] Comparison Figure 2-Figure 5As shown, the cover 9 is fixedly connected to a baffle 12 which is sealed with the adjacent carrier box 10, the baffle 12 is fixedly connected to a transmission rack 13, the left side of the rotating shell 11 passes through the adjacent carrier box 10 and is fixedly connected to a one-way gear 14, the transmission rack 13 is meshed with the one-way gear 14, when the transmission rack 13 moves forward, the one-way gear 14 drives the adjacent rotating shell 11 to rotate, when the transmission rack 13 moves backward, the one-way gear 14 cannot drive the adjacent rotating shell 11 to rotate, and a humidity sensor electrically connected to the adjacent control panel 2 is installed on the upper side of the cover 9.

[0037] When it is necessary to use a ring main unit for power distribution, the ring main unit is first installed, a housing 1 is fixed at a designated power distribution location, and then three connectors 3 are inserted into the fixed housing 1, and then another housing 1 is docked onto the three plugged connectors 3, and the intelligent power distribution terminal unit in the housing 1 is turned on through the control panel 2 to distribute power to the required location, and the isolated voltage module of the highly efficient integrated electronic voltage sensor 4 is collected, and the control panel 2 is built into the gap between the two housings 1, and the control panel 2, the voltage sensor 4 and the intelligent power distribution terminal unit are connected using a network cable, thereby shortening the line connection distance between the control panel 2, the voltage sensor 4 and the intelligent power distribution terminal unit, and reducing the connection length of the wires, thereby avoiding excessive consumption and waste of wires.

[0038] During the installation of the ring network cabinet, the wires between the two shells 1 are connected through the adapter 7, and the wires are connected between two adjacent adapters 7 with the same height, so that the wires do not need to be bent upward when connecting the upper end connection ports of the two shells 1, thereby reducing the bending angle of the cable during connection, thereby reducing the waste of wire length caused by excessive bending angles, and reducing the risk of wire breakage caused by bent wire connections.

[0039] After connecting the wires between two adjacent adapters 7 of the same height, the operator clamps the wires at different heights between two adjacent clamps 6 from bottom to top. The elastic parts of the clamps 6 store force so that the two clamps 6 clamp the wires to prevent the wires from being loosened due to the influence of the external environment. The cover 9 shields the adjacent adapters 7 and wires. The desiccant in the rotating shell 11 absorbs water vapor near the adjacent adapter 7 through the bottom of the adjacent carrier box 10, reducing the influence of water droplets or moisture in the external environment on the adapter 7, thereby reducing the risk of short circuit of the wires due to moisture or even electric shock to people.

[0040] When the external humidity decreases, the humidity sensor sends a command to the adjacent control panel 2, and the control panel 2 controls the adjacent electromagnetic slider 8 to slide forward, and the electromagnetic slider 8 drives the adjacent cover 9 to move forward, and the cover 9 drives the adjacent baffle 12 to move forward, and the baffle 12 loses the shielding of the upper side of the adjacent carrier box 10. At the same time, the baffle 12 drives the adjacent one-way gear 14 to rotate 180° through the adjacent transmission rack 13 during the forward movement, and the one-way gear 14 drives the adjacent rotating shell 11 to rotate 180°, so that the desiccant located on the lower side of the rotating shell 11 rotates to the upper side, and the desiccant in the rotating shell 11 is dried by sunlight. During the process, the desiccant located on the upper side of the rotating shell 11 is rotated to the lower side without contacting with the moisture in the air. When the humidity of the external environment rises again, the humidity sensor sends a command to the adjacent control panel 2. The control panel 2 controls the adjacent electromagnetic slider 8 to slide backward and reset. The electromagnetic slider 8 drives the adjacent transmission rack 13 to reset through the adjacent cover 9 and the adjacent baffle 12. The reset of the transmission rack 13 drives the adjacent one-way gear 14 to rotate. At this time, the one-way gear 14 cannot drive the adjacent rotating shell 11 to rotate. The desiccant rotated to the lower side in the rotating shell 11 absorbs the water vapor near the adjacent adapter 7 through the bottom of the adjacent carrier box 10.

[0041] Repeat the above steps, continuously turn over the desiccant in the rotating shell 11, dry the desiccant, improve the utilization rate of the desiccant in the rotating shell 11, reduce the frequency of desiccant replacement, and thus reduce material and labor costs. When the device needs to be repaired, the power supply of the device can be temporarily turned off through the control panel 2 and the device can be repaired.

[0042] The existing ring main unit uses granular desiccant to dehumidify the interior. However, after the desiccant is placed, it accumulates in the ring main unit, resulting in the outer layer of desiccant being saturated with water while the inner desiccant is still dry, resulting in extremely low utilization of the desiccant. In addition, personnel need to frequently replace the desiccant regularly, resulting in a large waste of resources and manpower.

[0043] Example 2: Based on Example 1, Figure 1 , Figure 7 , Figure 8 and Fig.10As shown, it also includes two linearly distributed carrying boxes 15 each loaded with desiccant, wherein the desiccant is a block desiccant formed by pressing small particles, and the linearly distributed carrying boxes 15 are respectively fixed in adjacent shells 1, and the position of the shell 1 close to the carrying boxes 15 is slidably connected to an electromagnetic slider 16 through an electromagnetic slide rail, and the electromagnetic slider 16 is electrically connected to the adjacent control panel 2, and the electromagnetic slider 16 is fixed to an elastic telescopic rod 17, and the initial state of the elastic telescopic rod 17 is compression storage, and the telescopic end of the elastic telescopic rod 17 is fixed to a useful The scraper 18 for scraping the desiccant is in close contact with the upper surface of the block desiccant. During the reciprocating movement of the scraper 18, the elastic force of the spring in the elastic telescopic rod 17 cannot drive the adjacent scraper 18 to insert into the dry block desiccant. When the upper surface of the block desiccant is moistened, the moistened portion of the block desiccant becomes soft, and the elastic force of the spring in the elastic telescopic rod 17 is sufficient to drive the adjacent scraper 18 to insert into the moistened portion of the block desiccant, so that the telescopic end of the elastic telescopic rod 17 gradually extends to scrape the desiccant layer by layer.

[0044] Comparison Figure 7-Figure 9 As shown, the outer shell 1 is slidably connected to an electromagnetic slider three 19 at a position near the adjacent carrying box two 15 through an electromagnetic slide rail, and the electromagnetic slider three 19 is electrically connected to the adjacent control panel 2. The electromagnetic slider three 19 is rotatably connected to a rotating box 20, and the upper part of the front side of the rotating box 20 is arc-shaped, which is used to always fit the rear side of the adjacent outer shell 1 during the rotation process. A torsion spring is fixed between the rotating box 20 and the adjacent electromagnetic slider three 19. The electromagnetic slider three 19 and the adjacent rotating box 20 are both located on the outside of the adjacent outer shell 1. The outer shell 1 is provided with a guide through hole one for connecting the adjacent rotating box 20 and the adjacent carrying box two 15, and the lower side of the guide through hole one is provided with an inclined surface, which is used to guide the scraped desiccant from the carrying box two 15 to the adjacent rotating box 20. A gravity sensor electrically connected to the adjacent control panel 2 is installed in the rotating box 20, wherein the gravity sensor is not shown in the figure.

[0045] Comparison Figure 6-Figure 9As shown, a hydraulic push rod 1 21 is fixedly connected to the upper side of the housing 1, and the telescopic end of the hydraulic push rod 1 21 is fixedly connected to the adjacent baffle 12. A hydraulic push rod 22 connected to the adjacent hydraulic push rod 1 21 through a conduit is fixedly connected to the housing 1 near the adjacent carrier box 2 15. The telescopic end of the hydraulic push rod 22 is fixedly connected to a rain cover 23 for covering the adjacent rotating box 20. The extension amount of the telescopic end of the hydraulic push rod 1 21 is the same as that of the telescopic end of the adjacent hydraulic push rod 22. When the baffle 12 moves forward, the adjacent rain cover 23 is synchronously moved backward, and the desiccant in the adjacent rotating housing 11 and the desiccant in the adjacent rotating box 20 are dried at the same time. The housing 1 is fixedly connected to a trigger frame 24 that is extruded and matched with the adjacent rotating box 20. The upper end of the trigger frame 24 is an arc surface, which is used to squeeze the adjacent rotating box 20. The trigger frame 24 is fixedly connected with an elastic telescopic rod 241, and the telescopic end of the elastic telescopic rod 241 is fixedly connected with a limit plate 25 which is squeezed and matched with the adjacent rotating box 20. The upper part of the rear side of the limit plate 25 is provided with a protruding portion, which is used for the rotating box 20 to squeeze the adjacent limit plate 25 to move downward when the adjacent rotating box 20 moves downward and flips. A carrier box 3 251 located below the adjacent carrier box 2 15 is fixedly connected in the shell 1. The shell 1 is provided with a guide through hole 2 for connecting the adjacent rotating box 20 and the adjacent carrier box 3 251. The guide through hole 2 is used to introduce the dried desiccant in the adjacent rotating box 20 into the adjacent carrier box 3 251 for secondary utilization of the desiccant, and the limit plate 25 slides in the adjacent guide through hole 2.

[0046] During the operation of the intelligent power distribution terminal unit, a block desiccant is placed in the carrier box 15. The desiccant in the carrier box 15 absorbs the moisture in the adjacent housing 1 to prevent the moisture content in the housing 1 from being too high, causing a short circuit in the wires or even a risk of leakage. During the use of the desiccant in the carrier box 15, the humidity sensor sends different instructions to the control panel 2 according to the external environmental humidity. The control panel 2 controls the adjacent electromagnetic slider 16 to slide back and forth regularly (for example, when the external environmental humidity is high, the electromagnetic slider 16 moves back and forth once every 4 hours, and when the external environmental humidity is low, the electromagnetic slider 16 moves back and forth once every 24 hours). The electromagnetic slider 16 moves back and forth once), the greater the humidity of the external environment, the higher the sliding frequency of the electromagnetic slider 16, the electromagnetic slider 16 drives the adjacent elastic telescopic rod 17 to slide back and forth, the telescopic end of the elastic telescopic rod 17 drives the adjacent scraper 18 to slide back and forth, the scraper 18 scrapes the surface of the desiccant in the adjacent carrier box 15 (the desiccant in the carrier box 15 is gradually scraped thin, the telescopic end of the elastic telescopic rod 17 drives the adjacent scraper 18 to gradually extend, so that the scraper 18 is always in close contact with the upper surface of the adjacent desiccant), scrapes off the upper layer of wet desiccant, keeps the upper surface of the desiccant dry, thereby improving the utilization rate of the desiccant.

[0047] After the scraper 18 scrapes off the upper layer of wetted desiccant, the scraped desiccant particles slide along the guide through hole 1 of the housing 1 into the adjacent rotating box 20. When the external humidity decreases and the baffle 12 repeats the steps of the above embodiment and moves forward, the baffle 12 drives the telescopic end of the hydraulic push rod 1 21 to move forward. The hydraulic push rod 1 21 extracts the hydraulic oil in the adjacent hydraulic push rod 2 22 through the conduit. The telescopic end of the hydraulic push rod 22 extends and drives the adjacent rain cover 23 to move backward. The rain cover 23 loses its covering of the adjacent rotating box 20. At this time, The humidity of the external environment is low, and the sunlight irradiates the desiccant that has fallen into the adjacent rotating box 20, so that the desiccant that has fallen into the adjacent rotating box 20 is gradually dried. When the humidity of the external environment rises, the baffle 12 repeats the steps of the above-mentioned embodiment to move backward and reset, and the baffle 12 drives the rain cover 23 to move forward and reset through the hydraulic transmission in the adjacent hydraulic push rod 1 21 and the adjacent hydraulic push rod 2 22, so that the rain cover 23 moves to the upper side of the adjacent rotating box 20 and covers it, thereby reducing the influence of water droplets on the dried desiccant in the rotating box 20.

[0048] When the telescopic end of the elastic telescopic rod 17 is extended to the limit and a certain amount of desiccant in the carrier box 2 15 is scraped off, the weight of the desiccant carried in the rotating box 20 increases. By presetting the sensing value of the gravity sensor, taking the half of the desiccant loaded into the adjacent carrier box 2 15 in the rotating box 20 as an example, the gravity sensor sends a command and controls the electromagnetic slider 3 19 to move downward through the adjacent control panel 2. The electromagnetic slider 3 19 moves downward, and the electromagnetic slider 3 19 drives the adjacent rotating box 20 to move downward. The rotating box 20 moves downward and squeezes the adjacent trigger frame 24 and the adjacent limit plate 25. The trigger frame 24 squeezes the adjacent rotating box 20 to flip, causing the torsion spring of the rotating box 20 to twist, and the limit plate 25 moves downward and squeezes The telescopic end of the adjacent elastic telescopic rod 241 moves downward and contracts, and the rotating box 20 pours the desiccant carried therein into the guide through hole 2 of the adjacent shell 1. The desiccant slides along the upper surface of the adjacent limiting plate 25 into the adjacent supporting box 3 251, so that the desiccant is dried and then returns to the shell 1 again to adsorb the moisture in the shell 1, thereby improving the utilization rate of the desiccant, thereby reducing the frequency of desiccant replacement, and further reducing material and labor costs. After the desiccant in the supporting box 2 15 has been used for a period of time, the remaining desiccant in the supporting box 2 15 is taken out and the supporting box 2 15 is cleaned, and then another piece of desiccant is put into the supporting box 2 15, and the desiccant in the supporting box 2 15 is regularly replenished.

[0049] Example 3: Based on Example 2, Figure 10-12As shown, it also includes a plurality of groups of switches 26 distributed in a straight line, each group of switches 26 is installed in adjacent housings 1 respectively, each group of switches 26 is distributed in a straight line, the switches 26 are electrically connected to the adjacent control panel 2, a cooling pipe 27 connected to an external cooler is fixedly connected to the position of the housing 1 near the adjacent switch 26, the external cooler is electrically connected to the adjacent control panel 2, an electromagnet 30 is fixedly connected to the position of the housing 1 near the adjacent switch 26, the electromagnet 30 is electrically connected to the adjacent switch 26 through a circuit line 29, a conductive plate 28 and a line, and a loop is provided in the circuit line 29, the adjacent conductive plate 28 and the line of the adjacent switch 26, so that a complete loop can be formed between the electromagnet 30 and the adjacent switch 26, and the larger the current in the line on the switch 26, the larger the current flowing to the adjacent electromagnet 30 through the adjacent conductive plate 28 and the adjacent circuit line 29. The larger the resistance, the greater the magnetic force of the electromagnet 30 is, and the current of the circuit on the adjacent switch 26 is proportional to the current. A resistance telescopic rod 31 is fixedly connected to the position of the housing 1 near the adjacent electromagnet 30. The resistance telescopic rod 31 is filled with a flexible block. When the telescopic end of the resistance telescopic rod 31 is extended, the flexible block inside is squeezed, and the flexible block is deformed, so that the telescopic end of the resistance telescopic rod 31 is subjected to resistance during the extension process, so as to prevent the adjacent magnetic block 32 from moving too fast when the telescopic end of the resistance telescopic rod 31 is extended, thereby causing the electromagnet 30 to be impacted by the adjacent magnetic block 32 and damaged. The telescopic end of the resistance telescopic rod 31 is fixedly connected with a magnetic block 32 that is magnetically matched with the adjacent electromagnet 30, and an elastic member is fixedly connected between the resistance telescopic rod 31 and the adjacent magnetic block 32, wherein the elastic member is a tension spring. A regulating valve 33 is installed on the cooling pipe 27, and the regulating valve 33 is an existing ball valve structure. Fig.12 As a reference, when the valve of the regulating valve 33 rotates counterclockwise, the amount of coolant flowing through the adjacent regulating valve 33 in the cooling pipe 27 gradually increases; when the valve of the regulating valve 33 rotates clockwise, the amount of coolant flowing through the adjacent regulating valve 33 in the cooling pipe 27 gradually decreases until it is closed; the regulating valve 33 and the telescopic end of the adjacent resistance telescopic rod 31 are driven by a gear rack; the gear is fixedly connected to the valve of the adjacent regulating valve 33 to drive the valve of the regulating valve 33 to rotate; the rack is fixedly connected to the telescopic end of the adjacent resistance telescopic rod 31; an insulating shell 34 is fixedly connected near the adjacent linearly distributed switches 26 in the housing 1; the connecting end of the cable on the switch 26 is located in the adjacent insulating shell 34; the electromagnet 30, the adjacent circuit line 29, the adjacent conductive plate 28 and the circuit of the adjacent switch 26 are also located in the adjacent insulating shell 34; the insulating shell 34 is provided with a dry insulating gas filled therein to reduce the influence of the external environment on the connecting end of the cable on the switch 26 and to insulate the connecting end of the cable on the switch 26.

[0050] Comparison Fig.12As shown, the switch 26 on the left side of the housing 1 is fixedly connected to a casing 35, and the casing 35 is filled with thermal expansion gas. When the temperature at the switch 26 is lower than its optimal operating temperature range, the thermal expansion gas contracts, and when the temperature at the switch 26 is higher than its optimal operating temperature range, the thermal expansion gas expands. The casing 35 is sealingly and slidably connected to a connecting rod 351, and an elastic member is fixedly connected between the casing 35 and the adjacent connecting rod 351, wherein the elastic member is a tension spring, and when the thermal expansion gas expands and squeezes the connecting rod 351 to move downward, the elastic member stretches, and the connecting rod 351 is fixedly connected to an insulating plate 36, and the insulating plate 36 is fixedly connected to the adjacent conductive plate 28.

[0051] Comparison Fig.12 As shown, the connecting rod 351 is fixedly connected with a heat-conducting rod 37 , and the switch 26 is in contact with and cooperates with the adjacent heat-conducting rod 37 , so as to enable the switches 26 distributed in adjacent straight lines to conduct heat to each other when the external ambient temperature is low.

[0052] During the operation of the intelligent power distribution terminal unit, since each load (such as a motor, lighting system, heating equipment, etc.) has different power requirements, each switch 26 and its line allocate different amounts of electricity, which causes the line port of each switch 26 to have a temperature difference due to the difference in electricity. The current of the line on the switch 26 is transmitted to the adjacent electromagnet 30 through the adjacent conductive plate 28 and the adjacent circuit line 29, so that the electromagnet 30 is energized and has magnetic force. The greater the current, the greater the magnetic force of the electromagnet 30. The electromagnet 30 drives the adjacent magnetic block 32 to move to the right through the magnetic force, and the elastic member of the resistance telescopic rod 31 stretches. The magnetic block 32 drives the telescopic end of the adjacent resistance telescopic rod 31 to move to the right. The telescopic end of the resistance telescopic rod 31 transmits the adjacent gear rack in the process of moving to the right. The gear rotates and adjusts the flow rate of the adjacent regulating valve 33, so that the flow rate of the coolant flowing through the adjacent regulating valve 33 in the cooling pipe 27 increases, and the cooling force of the cooling pipe 27 is increased. The cooling force of the cooling pipe 27 is adjusted according to the heat generated by the current in the switch 26, so that the line connection port of the switch 26 maintains a constant optimal working temperature, avoiding the increase of the risk of short circuit and fire caused by excessive temperature at the switch 26.

[0053] When the temperature of the switch 26 is lower than its optimal working temperature, the thermal expansion gas in the casing 35 cools and contracts, causing the elastic part of the connecting rod 351 to contract and drive it to move upward, the connecting rod 351 drives the adjacent insulating plate 36 to move upward, the insulating plate 36 drives the adjacent conductive plate 28 to move upward, causing the conductive plate 28 to lose contact with the adjacent circuit line 29, the circuit line 29 contacts the adjacent insulating plate 36, the current of the conductive plate 28 no longer flows through the adjacent circuit line 29 to the adjacent electromagnet 30, the electromagnet 30 loses its magnetic force, the elastic part of the resistance telescopic rod 31 resets and drives its telescopic end and the adjacent magnetic block 32 to move leftward, the telescopic end of the resistance telescopic rod 31 transmits the adjacent gear rack in the process of moving to the left, the gear rotates and adjusts the flow of the adjacent regulating valve 33. The flux is adjusted so that the flow of coolant flowing through the adjacent regulating valves 33 in the cooling pipe 27 is reduced. When the telescopic end of the resistance telescopic rod 31 is contracted to the limit position, the regulating valve 33 stops flowing, and the switch 26 is no longer cooled. At this time, the connecting rod 351 drives the adjacent heat-conducting rod 37 to move upward, so that the switch 26 contacts the adjacent heat-conducting rod 37. The three switches 26 conduct heat to each other through a heat-conducting rod 37, and the temperature of the switch 26 with a larger current is transferred to the switch 26 with a smaller current, so that the temperatures of the three switches 26 are balanced, preventing the switch 26 with the smallest current from becoming brittle or even broken or damaged due to too low temperature, thereby causing current leakage at the switch 26, thereby increasing the risk of short circuit and fire.

[0054] When it is necessary to stop using the device or to overhaul the device, turn off the intelligent power distribution terminal unit, voltage sensor 4, electromagnetic slider 1 8, electromagnetic slider 2 16, electromagnetic slider 3 19 and switch 26 of the device through the control panel 2. After overhauling the device, repeat the above steps and turn on the intelligent power distribution terminal unit of the device for use again.
