Description

Technical Field

[0002] Ring main unit is an important power equipment used for the distribution and control of ring power system. It has the advantages of compact structure, small size and moderate price. It is widely used in urban power grids and industrial fields. Ring main unit can play an important role in various environments, especially in urban power distribution network, it can effectively manage and distribute power resources.

[0003] However, during winter use, the electrical appliances and wires inside the ring network cabinet will generate heat, causing the temperature inside the ring network cabinet to rise. This temperature rise will easily cause condensation inside the ring network cabinet. If the anti-condensation measures inside the ring network cabinet (box) are insufficient, condensation is likely to occur when encountering humid weather or large temperature changes, which will seriously endanger the normal operation of the equipment and even cause a serious accident of equipment burning. The existing method of installing a heater to ensure that the temperature of the inner wall of the ring network cabinet is higher than the dew point temperature is a simple and effective anti-condensation method.

The hot air flow will smoothly enter the hot air flow channel according to the chimney effect, and then exchange heat with the cabinet facing the rear side of the instrument room and the mechanism room, so that part of the heat is transferred to the instrument room and the mechanism room;

[0016] S2: When condensation is generated in the installation shell, the fixing rod drives the first adsorption shell and the second adsorption shell to move downward, and the first adsorption shell and the second adsorption shell adsorb the condensation generated on the inner wall of the installation shell;

[0017] S3: when the temperature in the installation shell is too high, start the fan, and the fan sucks the air between the fixed baffle and the adjacent wind shield into the installation shell to reduce the temperature in the installation shell;

[0020] The present invention moves the activated carbon in the first adsorption shell and the second adsorption shell in the installation shell to clean the condensation appearing in the installation shell. At the same time, the activated carbon in the first adsorption shell and the second adsorption shell can be dried when in use, so that the activated carbon can be used continuously. When in use, the first adsorption shell and the second adsorption shell are moved to the first air outlet to reduce the moisture entering the cavity in the installation shell, reduce the probability of condensation, and thus improve the safety of the ring network cabinet.

When it rains, the fixing frame is blocked by the sealing plate to prevent rainwater from entering the ring network cabinet.

[0022] When there is an unexpected power outage, the fixing part of the present invention automatically falls down to seal the installation shell to prevent rainwater from entering the installation shell. At this time, normal ventilation is carried out through the first air outlet and the second air outlet. When there is too much rain, the expansion of the expansion water stop strip drives the second filter plate to block the first filter plate, and then blocks the installation shell to prevent rainwater from entering the installation shell.

DETAILED DESCRIPTION

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] Embodiment 1: A ring main unit that uses its own energy to prevent condensation, such as Figure 1-Figure 7 and Fig.10As shown, it includes a mounting shell 11, on which two groups of switch doors are arranged on the left and right sides. The mounting shell 11 is composed of a square shell and a top cover. The mounting shell 11 is fixedly connected with two first fixed plates 111 symmetrically distributed on the left and right sides and two fixed baffles 19 symmetrically distributed on the left and right sides. The two fixed baffles 19 are located below the two first fixed plates 111 and between the two first fixed plates 111. The mounting shell 11 is fixedly connected with two square plates 12 symmetrically distributed on the left and right sides. The square plates 12 are located on the upper sides of the adjacent first fixed plates 111. The lower sides of the square plates 12 are fixedly connected with springs 14 distributed equidistantly. Initially, the springs 14 store force, and the lower sides of the springs 14 are fixedly connected with sealing blocks 13. The mounting shell 11 and the first fixed plates 111 are both sealed and slidable with the adjacent sealing blocks 13. The mounting shell 11 is connected, and square holes which are symmetrically and equidistantly distributed and respectively sealed with adjacent sealing blocks 13 are provided. The number of square holes on the mounting shell 11 is equal to the number of sealing blocks 13. The mounting shell 11 is installed with a cabinet 101. A heat flow channel 102 is provided on the top of the cabinet 101. The heat flow channel 102 is connected with the air box of the cabinet 101. The heat flow channel 102 guides the heat flow in the air box. The rear side of the heat flow channel 102 is provided with a corrugated plate to increase the heat exchange rate. A heat insulating interlayer is provided on the top of the cabinet 101 to reduce the heat flow from the top. To make the heat flow flow into the instrument room and the mechanism room as much as possible, the mounting shell 11 is provided with two sets of symmetrically distributed electric slide rails. An electric slider 15 is provided on the electric slide rails of the mounting shell 11. A fixing rod 16 is fixed between the electric sliders 15 of the group, and the fixing rod 16 is slidably and rotatably connected with the first adsorption shell 17 and the second adsorption shell 171 distributed equidistantly. The second adsorption shell 171 and the first adsorption shell 17 are water-permeable and air-permeable. The first adsorption shell 17 and the second adsorption shell 171 on the same fixing rod 16 are staggered, and the frontmost is the first adsorption shell 17. The first adsorption shell 17 and the second adsorption shell 171 are respectively squeezed and matched with the adjacent sealing block 13. When the first adsorption shell 17 or the second adsorption shell 171 rises, the first adsorption shell 17 or the second adsorption shell 171 squeezes the adjacent sealing block 13 to make the sealing block 13 rise. The first adsorption shell 17 and the second adsorption shell 171 are filled with activated carbon, which is used to absorb moisture in the air. To keep the air in the mounting shell 11 dry, a temperature detector, a humidity monitor and a control unit are arranged in the mounting shell 11, an adjusting component for adjusting the position of the adjacent first adsorption shell 17 and the adjacent second adsorption shell 171 thereon is arranged on the fixing rod 16, a foam layer is arranged on the rear side and the switch door of the mounting shell 11 to hinder heat exchange, the fixed baffle 19 is made of heat-resistant material, the left and right sides of the mounting shell 11 are made of heat-conductive material, the left and right sides of the mounting shell 11 are provided with equidistantly distributed first air outlet holes 191 and equidistantly distributed second air outlet holes 192, the second air outlet holes 192 are sealed and rotatably connected with a one-way baffle 193, and the fixed baffle 19 is fixedly connected with a windshield 20 which contacts and cooperates with the adjacent first adsorption shell 17 and the adjacent second adsorption shell 171.

[0042] like Figure 5 and Figure 7-Figure 9 As shown, the adjustment component includes a one-way gear ring 2, which has an inner and outer layer. The inner layer of the one-way gear ring 2 is rotatably connected to the front side of the adjacent fixed rod 16. The fixed rod 16 is threadedly connected to a rotating ring 21. The thread on the fixed rod 16 is a reciprocating thread. When the rotating ring 21 rotates, the rotating ring 21 continuously moves back and forth under the drive of the reciprocating thread on the adjacent fixed rod 16. Four round rods are fixedly connected to the inner layer of the one-way gear ring 2. The one-way gear ring 2 is slidably connected to the adjacent rotating ring 21 through the round rods. The round rods on the one-way gear ring 2 are used to drive the adjacent rotating ring 21 to rotate. The rotating ring 21 is rotatably connected to a transmission member 22. The transmission member 22 is formed by fixing two front and rear rings and four middle round rods. The transmission member 22 is rotatably connected to the adjacent first adsorption shell 17, and the mounting shell 11 A symmetrically distributed rack 23 is fixed to the lower side, and the rack 23 is meshed with the adjacent one-way gear ring 2. Two groups of evenly spaced grooves are opened on the fixed rod 16. The first adsorption shell 17 and the second adsorption shell 171 are respectively limited by the grooves on the adjacent fixed rod 16. The two groups of grooves on the fixed rod 16 are inclined in opposite directions. The front and rear lengths of the first adsorption shell 17 and the second adsorption shell 171 are the same (the front and rear lengths of the first adsorption shell 17 are set to one length unit). When the first adsorption shell 17 and the second adsorption shell 171 move backward by one length unit, when the first adsorption shell 17 and the second adsorption shell 171 are both rotated 180 degrees, and the rotation directions are opposite, a fan 24 is provided on the lower side of the fixed baffle 19, and the fan 24 is used to accelerate the circulation of air in the mounting shell 11.

[0043] like Figure 7 and Figure 8 As shown, a first limit plate 18 is fixedly connected between two symmetrically distributed electric sliders 15 in the same group. The first limit plate 18 is composed of equidistantly distributed vertically placed plates and horizontal plates connecting them, and a triangular plate is fixedly connected to the upper side of the vertically placed plates. The first limit plate 18 fits with the mounting shell 11, and the first limit plate 18 is used to guide the condensation on the inner wall of the mounting shell 11 toward the adjacent first adsorption shell 17 or the second adsorption shell 171.

[0044] During normal operation, the primary main circuit conductor and electrical connection of the gas box carry a working current of 50HZ, which causes working heat generation. The heat will be transferred inside the gas box through heat conduction, convection heat dissipation, thermal radiation and the like, causing the temperature inside the gas box to rise and generate hot air flow. According to the chimney effect, the hot air flow will smoothly enter the hot flow channel 102, and then exchange heat with the cabinet 101 facing the rear side of the instrument room and the mechanism room, so that part of the heat is transferred to the instrument room and the mechanism room, so that the temperature inside the instrument room and the mechanism room is higher than the dew point temperature, thereby achieving the low-carbon requirements without introducing additional electric heaters, while improving the anti-condensation effect.

[0045] When the device is used in winter, due to the cold external temperature, condensation is easily generated when the air inside the mounting shell 11 contacts its inner wall. Since there is a foam layer inside the rear side of the mounting shell 11, the heat transfer speed of the rear side of the mounting shell 11 is slow and condensation will not be generated. However, the left and right sides of the mounting shell 11 have high heat transfer efficiency. Due to the cold external temperature, the left and right sides of the mounting shell 11 have low temperatures. When the air inside the mounting shell 11 contacts its left and right side walls, the hot air releases heat and condensation is generated on the left and right sides of the mounting shell 11. When the humidity monitor detects that the humidity inside the mounting shell 11 is too high, the control unit starts the electric slider 15. The two electric sliders 15 in the same group drive the fixing rod 16 to move downward. Taking one fixing rod 16 as an example, during the downward movement of the fixing rod 16, the fixing rod 16 drives the parts on it to move downward, and the first adsorption shell 17 and the second adsorption shell 171 move downward. The first adsorption shell 17 and the second adsorption shell 171 are pressed against the mounting shell 1 1 is adsorbed, the fixed rod 16 drives the one-way gear ring 2 to move downward, and the one-way gear ring 2 gradually contacts the adjacent rack 23 during the downward movement, and the one-way gear ring 2 drives the rotating ring 21 to rotate, and the rotating ring 21 moves backward under the action of the reciprocating thread, and the rotating ring 21 moves backward, and the rotating ring 21 drives the adjacent first adsorption shell 17 to move backward through the transmission member 22, and the first adsorption shell 17 squeezes the adjacent second adsorption shell 171 to move backward, and the first adsorption shell 17 rotates upward under the limit of the adjacent groove on the fixed rod 16, and the second adsorption shell 171 rotates downward under the limit of the adjacent groove on the fixed rod 16, when the rotating ring 21 moves backward by one length unit (the length of the front and rear squares of the first adsorption shell 17 is one length unit), the electric slider 15 no longer moves, and at this time the first adsorption shell 17 rotates upward by 180 degrees, and the second adsorption shell 171 rotates downward by 180 degrees, and the first adsorption shell 17 just moves to the position of the second adsorption shell 171 on the left.

[0046] After the above actions are completed, the electric slider 15 starts to move upward, and drives the parts thereon to move upward synchronously. During the rising process of the one-way gear ring 2, the rotating ring 21 is not driven to rotate. At this time, the equidistantly distributed first adsorption shell 17, the second adsorption shell 171 and the first limit plate 18 move upward. During the upward movement of the first limit plate 18, part of the condensation is guided toward the adjacent first adsorption shells 17 on both sides. The first adsorption shell 17 continues to adsorb the condensation, and then the first adsorption shell 17 continues to move upward. During the upward movement, the first adsorption shell 17 gradually contacts the adjacent sealing block 13 and squeezes the sealing block 13 to move upward. The sealing block 13 opens the hole adjacent to the mounting shell 11, and the adjacent spring 14 is compressed. The upper first adsorption shell 17 moves to the position of the hole on the mounting shell 11, so that the first adsorption shell 17 is connected to the outside world, and the moisture adsorbed by the activated carbon in the first adsorption shell 17 is evaporated by the irradiation of external sunlight, so that the activated carbon in the first adsorption shell 17 is dried again.

[0047] When the humidity monitor detects that the humidity in the mounting shell 11 drops, the control unit controls the electric slider 15 to drop, and the first adsorption shell 17 or the second adsorption shell 171 is located at the position adjacent to the first air outlet 191 through transmission. The first adsorption shell 17 and the second adsorption shell 171 block the outside air from entering the mounting shell 11 to a certain extent. At the same time, the air entering the first air outlet 191 will first pass through the adjacent first adsorption shell 17 or the adjacent second adsorption shell 171. The first adsorption shell 17 and the adjacent second adsorption shell 171 adsorb moisture in the air to reduce the moisture in the mounting shell 11 at the source. The control unit periodically dries the activated carbon in the first adsorption shell 17 and the second adsorption shell 171 during the time period with high sunlight according to local conditions to reduce condensation at the source.

[0048] When the temperature detector detects that the temperature inside the ring network cabinet is too high and the installation shell 11 needs to be cooled down quickly, the control unit controls the electric slider 15 to descend so that the first adsorption shell 17 and the second adsorption shell 171 are in a horizontal state, and then the electric slider 15 is closed. At this time, the first adsorption shell 17 and the second adsorption shell 171 are in contact with the adjacent wind shield 20, and then the fan 24 is started. The fan 24 sucks the air between the fixed baffle 19 and the adjacent wind shield 20 and discharges it into the installation shell 11. The air originally located in the installation shell 11 is cooled near the side wall of the installation shell 11, and then passes through the baffle composed of the first adsorption shell 17 and the second adsorption shell 171 to absorb the moisture therein, and then continues to flow driven by the fan 24, and the air temperature in the installation shell 11 is reduced by the self-circulation of the air inside the installation shell 11.

[0049] In normal state, wind enters the mounting shell 11 through the first air outlet 191 on one side, passes through the first adsorption shell 17 or the second adsorption shell 171, and is then discharged through the second air outlet 192 and the first air outlet 191 on the other side. In the process of wind being discharged through the second air outlet 192, the wind pushes open the adjacent one-way baffle 193 to allow air circulation.

[0050] When the first adsorption shell 17 is dried and the electric slider 15 descends, the electric slider 15 moves the first adsorption shell 17 downward through transmission. During the downward movement of the first adsorption shell 17, the sealing block 13 is gradually reset under the action of the adjacent spring 14, and the sealing block 13 gradually seals the hole on the mounting shell 11.

[0051] Embodiment 2: Based on embodiment 1, Figure 1 , Fig.11 and Fig.12As shown, it also includes two groups of evenly spaced fixed frames 3, both of which are fixedly connected to the top cover of the mounting shell 11, and two adjacent fixed frames 3 in the same group are fixedly connected, the front fixed frame 3 is tilted downward from back to front, and the rear fixed frame 3 is tilted downward from front to back, and the fixed frame 3 is rotatably connected to three evenly spaced rotating plates 32, the center of gravity of the three rotating plates 32 does not coincide with the rotating shaft, so that the three rotating plates 32 are in a vertical state when no force is applied, and symmetrically distributed filter screens 33 are fixedly connected between the rotating plates 32 and adjacent fixed frames 3, and the filter screens 33 are used to filter impurities and dust in the air.

The square bars are used to guide rainwater downward to prevent rainwater from entering the mounting shell 11. Initially, the fixing parts 43 are in an open state, and the square baffles and the symmetrically distributed square bars are sealed with adjacent fixing frames 3. The second limit plate 4 is slidably connected with a sliding frame 44. Initially, the sliding frame 44 is located at the adjacent second limit plate 4. On the upper side of the positioning plate 4, symmetrically distributed fixing parts 43 are slidably and rotatably connected with symmetrically distributed sliding frames 44, and the sliding frames 44 are used to control the movement of the fixing parts 43. The upper parts of both sides of the square shell of the mounting shell 11 are provided with electric rotating shafts 45, and the electric rotating shafts 45 can rotate after power failure. The upper side of the second limiting plate 4 is rotatably connected with a rotating shaft 46, and the electric rotating shaft 45 and the adjacent rotating shaft 46 are fixedly connected with sprockets. The sprocket on the electric rotating shaft 45 and the sprocket on the adjacent rotating shaft 46 are transmitted through a chain 47, and the chain 47 is fixedly connected to the adjacent sliding frame 44, and the front side of the chain 47 is fixedly connected to the adjacent sliding frame 44, and the rear side of the chain 47 passes through the adjacent sliding frame 44.

[0054] like Fig.11 and Fig.12As shown, a cavity is opened on the lower side of the first filter plate 49, and an expansion water stop strip 410 is installed in the cavity of the first filter plate 49. The expansion water stop strip 410 swells when it comes into contact with water. The first filter plate 49 is sealingly and slidably connected with the second filter plate 411. Initially, the holes on the second filter plate 411 are aligned with the holes on the adjacent first filter plate 49, and the second filter plate 411 is squeezed and matched with the adjacent expansion water stop strip 410. When the expansion water stop strip 410 comes into contact with water, the expansion water stop strip 410 squeezes the second filter plate 411, and the second filter plate 411 moves upward to block the filter holes on the adjacent first filter plate 49. Two symmetrically distributed water diversion grooves are opened on the lower side of the mounting shell 11.

[0055] like Fig.16 As shown, a second fixing plate 5 is fixedly connected to the top of the mounting shell 11, an electric telescopic rod 51 is fixedly connected to the second fixing plate 5, a limiting block 52 is fixedly connected to the telescopic end of the electric telescopic rod 51, a sealing plate 53 is sealingly rotatably connected to the lower side of the fixing frame 3, the sealing plate 53 is squeezed and matched with the limiting block 52, and when the limiting block 52 moves upward, all the sealing plates 53 are squeezed to move upward, and a water diversion groove is provided on the fixing frame 3.

[0056] When the weather is hot, ventilation is performed through the fixing frame 3. When wind blows from the front to the rear, the rotating plate 32 is in a vertical state under the action of gravity, and the wind moves downward under the guidance of the fixing member 43. Then, the wind passes through the filter screen 33 when blowing, so that the wind enters downward into the mounting shell 11, and then moves vertically downward under the guidance of the sealing plate 53.

[0057] When the detector detects rain, the electric telescopic rod 51 is started, and the telescopic end of the electric telescopic rod 51 drives the limit block 52 to move upward. The limit block 52 squeezes the sealing plates 53 on both sides, and the sealing plates 53 gradually enter the adjacent fixing frame 3 to seal the interior of the mounting shell 11. Then the rain falls on the filter screen 33 to clean the filter screen 33. At the same time, the water falling on the sealing plate 53 is discharged from the drainage hole on the fixing frame 3.

[0058] After the rain stops, the electric telescopic rod 51 is started, the telescopic end of the electric telescopic rod 51 is reset, and the telescopic end of the electric telescopic rod 51 drives the limit block 52 to move downward, and the sealing plate 53 is separated from the fixing frame 3 under the action of gravity.

[0059] During use, if there is an accidental power outage, the electric shaft 45 is disconnected through the control terminal. At this time, the sliding frame 44 moves downward under the action of gravity, the sliding frame 44 drives the chain 47 to move, and the sliding frame 44 drives the fixing part 43 to rotate downward. The two fixing parts 43 drive the soft board 42 to deform, and the fixing part 43 gradually rotates to contact with the fixing frame 3. After the fixing part 43 contacts the adjacent fixing frame 3, the top of the mounting shell 11 is blocked to prevent rainwater from entering the mounting shell 11. At this time, normal ventilation is carried out through the first air outlet 191.

[0060] In the process of the sliding frame 44 moving downward, the adjacent sliding telescopic rod 48 is driven to move downward, and the sliding telescopic rod 48 drives the first filter plate 49 to move downward. At the same time, the cavity on the first filter plate 49 is located near the groove on the lower side of the mounting shell 11. At this time, if the water level of rainwater gradually rises to the lower side of the first filter plate 49, the rainwater contacts the expansion water stop strip 410 through the groove on the lower side of the mounting shell 11 and the cavity of the first filter plate 49 in turn. The expansion water stop strip 410 expands and squeezes the adjacent second filter plate 411 during the expansion process. The second filter plate 411 rises to block the filter holes on the first filter plate 49 to prevent rainwater from entering the mounting shell 11, causing damage to the wires in the mounting shell 11 and leakage. After the rain stops, the electric shaft 45 starts and rotates the fixing member 43 upward through transmission to reset the fixing member 43.

[0061] Embodiment 3: Based on Embodiment 2, a method for preventing condensation of a ring main unit using its own energy is provided, and the specific steps are as follows:

[0062] S1: The air box of the cabinet 101 is transferred through heat conduction, convection heat dissipation, heat radiation, etc., which will cause the temperature inside the air box to rise and generate hot air flow. The hot air flow channel 102 allows the hot air flow to smoothly enter the hot air flow channel 102 according to the chimney effect, and then exchanges heat with the cabinet 101 facing the back of the instrument room and the mechanism room, so that part of the heat is transferred to the instrument room and the mechanism room; S2: When condensation is generated in the installation shell 11, the fixing rod 16 drives the first adsorption shell 17 and the second adsorption shell 171 to move downward, and the first adsorption shell 17 and the second adsorption shell 171 adsorb the condensation generated on the inner wall of the installation shell 11;

[0063] S3: When the temperature inside the installation shell 11 is too high, the fan 24 is started, and the fan 24 sucks the air between the fixed baffle 19 and the adjacent windshield 20 and discharges it into the installation shell 11 to reduce the temperature inside the installation shell 11;

[0064] S4: When it rains, the sealing plate 53 gradually enters into the adjacent fixing frame 3, seals the interior of the mounting shell 11, and cleans the filter screen 33 with rainwater.

[0065] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
