Description

Technical Field

[0001] The invention relates to the technical field of distribution boxes, and in particular to an integrated distribution box for a power grid. Background Art

[0002] As the final equipment of my country's power system, the distribution box contains isolating switches (knife switches), molded case circuit breakers, miniature circuit breakers, capacitors, current transformers, surge protectors, meters, dual power supply switches, contactors, thermal relays and other electrical components to distribute different transmission lines to ensure the normal operation of the power system. At the same time, the distribution box also undertakes the core tasks of electrical protection, electric energy metering and over-voltage and under-voltage protection, which can effectively prevent the occurrence of electrical accidents, reduce the risk of electrical failures, prevent the expansion of failures, and protect the safety of electrical equipment and personnel.

[0003] When the existing distribution box is working outdoors in winter, the door gaps, wiring holes, and ventilation holes of the distribution box are prone to ice. Usually, a heating mechanism is set at the door gap to prevent the door and the box from freezing. However, this design will inevitably increase energy consumption, and the temperature inside the box is too high, which affects the use of electrical components. The heat emitted by the electrical components themselves cannot be effectively used to melt the ice on the frozen parts, which is not conducive to energy saving and environmental protection. It is not difficult to see from this that the existing technology solves the problem of ice forming in the door gaps due to the low temperature of the distribution box by using heating equipment to melt the ice, and solves the problem of the high temperature of the distribution box by using cooling equipment to accelerate the heat dissipation of the electrical components. This will inevitably lead to the following problems: the use of heating equipment in winter wastes the heat emitted by the electrical components themselves, which is not conducive to energy saving and environmental protection. Chinese invention patent specification CN 116845753B discloses a distribution box, including a box body, a box door is rotatably installed on the front side of the box body, a sealing ring is provided on the front side of the box body, a mounting plate is provided inside the box body, a pair of side plates are symmetrically fixedly connected to the front side of the mounting plate, a rotating shaft is rotatably installed between the pair of side plates on the same side, a cover plate is fixedly sleeved on the outside of the rotating shaft, and the surface of the cover plate and the box body are provided with corresponding multiple vents. This technical solution can achieve the sealing of electrical equipment in the box body when the outside temperature is low, and use the heat dissipated by the electrical equipment itself to heat the sealing ring between the box door and the box body, thereby avoiding the situation where the box door cannot be opened due to ice at the sealing ring. However, the positions where the distribution box is prone to ice formation are not only at the door gap, but also at the ventilation holes and the wiring holes, and the above invention does not clearly describe the relevant technical solutions. At the same time, this technical solution does not fully store the heat generated by the electrical components when working outdoors in winter, and does not effectively utilize the stored heat. For example, it only melts ice at the door gaps while ignoring the wiring holes and ventilation holes. In addition, this technical solution uses natural convection to melt ice, which results in a slow ice melting process. When this technical solution works outdoors in summer, the heat generated by the electrical components is mainly dissipated through the ventilation holes, resulting in limited heat dissipation effect of the distribution box.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] 1. When the temperature control system of the integrated power distribution box of the power grid is in the retracted state, the left and right pipes are close to the left and right sides of the water tank, there is a fixed spacing between the mounting plate and the rear end face of the box, the shielding cloth completely covers the electrical components and the water tank, and the wind shield is close to the box.

[0016] 3. The integrated power distribution box of this power grid utilizes the linkage structure of the temperature control system to realize the synchronous movement between the left pipeline, the right pipeline, the mounting plate, the shielding component, and the wind shielding component, simplifying the operation steps of the temperature control system so that the temperature control system of the integrated power distribution box of this power grid can quickly switch to different working states to cope with different working occasions.

At the same time, water vapor is used to melt the ice instead of water to prevent the water transported past from freezing due to the low temperature at the door gap or the vents.

[0027] In the description of this embodiment, it should also be noted that, unless otherwise clearly specified and limited, the terms “set”, “connected” and “connected” should be understood in a broad sense.

[0028] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] refer to Figures 1 to 7The present embodiment discloses a power grid integrated distribution box, including a box body 100 and a door 110. The box body 100 is provided with ventilation holes and wiring holes, and a mounting plate 120 is arranged inside. The mounting plate 120 is provided with electrical components 121; the temperature control system 200 is also included. The temperature control system 200 includes a circulation component 210. The circulation component 210 can realize liquid circulation inside the circulation component 210. The circulation component 210 includes a heat exchange component 211, a left pipeline 212, a right pipeline 213, and a middle pipeline 214; the heat exchange component 211 is close to the electric The device element 121, the left pipeline 212 and the right pipeline 213 are located on both sides of the heat exchange component 211, and one end of both are connected to the heat exchange component 211, and the other end of both are connected to the middle pipeline 214; the middle pipeline 214 surrounds the wiring hole of the box body 100; when the temperature control system 200 is in a retracted state, the left pipeline 212 and the right pipeline 213 are close to the outer surface of the heat exchange component 211; when the temperature control system 200 is in an extended state, the left pipeline 212 and the right pipeline 213 are close to the inner surface of the box body 100.

[0030] Furthermore, the heat exchange component 211 includes a water tank, which is installed on the front side of the mounting plate 120 and surrounds the electrical component 121; the circulation component 210 also includes a water pump 215; the middle part of the left pipeline 212 and the right pipeline 213 adopts an S shape; the left pipeline 212 and the right pipeline 213 are connected to the water tank with a hose, and sufficient margin is left; the middle pipeline 214 is fixed at the wiring hole, and the middle pipeline 214 is connected to the left pipeline 212 and the right pipeline 213 with a hose, and sufficient margin is left; when the temperature control system 200 is in a retracted state, the left pipeline 212 and the right pipeline 213 are not in direct contact with the inner surface of the box body 100; when the temperature control system 200 is in an extended state, the left pipeline 212 and the right pipeline 213 are not in direct contact with the outer surface of the water tank.

[0031] When the present embodiment is in use, the integrated power distribution box of the power grid is provided with a mounting plate 120 inside its box body 100, and the mounting plate 120 is provided with electrical components 121 and a water tank; the wires connected to the electrical components 121 are connected to the external circuit through the wiring holes; the water tank surrounds the electrical components 121 and is close to the electrical components 121, and does not interfere with the wiring arrangement of the wires and the installation and maintenance of the electrical components 121. When the electrical components 121 are working, the electrical components 121 generate heat, and the heat is transferred to the mounting plate 120 and the water tank in sequence by mainly heat conduction. The mounting plate 120, the outer wall of the water tank and the water carried in the water tank are all absorbing heat. The water containing heat in the water tank is pumped to the left pipeline 212 by the water pump 215, and flows through the middle pipeline 214 and the right pipeline 213 in sequence, and the water with lower temperature in the pipeline is pushed to the water tank. This process is continuously circulated, thereby realizing the forced convection of heat in the circulation component 210. When the temperature control system 200 is in the retracted state, the left pipe 212 and the right pipe 213 are close to the outer surface of the water tank. At this time, the heat in the water tank mainly enters the pipe of the circulation component 210 through heat conduction and forced convection, thereby improving the heat transfer speed; since the middle pipe 214 surrounds the cable hole of the box body 100, the circulation component 210 continuously transports the heat generated by the electrical component 121 to the cable hole through water circulation, thereby effectively improving the temperature at the cable hole; when the power grid integrated distribution box is working outdoors in winter, the temperature at the cable hole is generally above the freezing temperature of water, which can effectively prevent the cable hole from freezing, thereby reducing the risk of cable sheath rupture due to cable freezing. When the temperature control system 200 is in an extended state, the left pipe 212 and the right pipe 213 are close to the inner surface of the box body 100. At this time, the water in the water tank can quickly transfer the heat generated by the electrical component 121 to the pipe, and the pipe begins to dissipate heat. When the pipe is in direct contact with the inner surface of the box body 100, the heat in the pipe is quickly transferred to the box body 100 by heat conduction, thereby increasing the heat dissipation area of ​​the electrical component 121 and accelerating the dissipation of heat generated by the electrical component 121. When the power grid integrated distribution box works outdoors in summer, the life of the electrical component 121 can be shortened or failure caused by high temperature can be reduced.

[0032] As a further solution of this embodiment: the mounting plate 120 can move along the front and rear direction of the box body 100; when the temperature control system 200 is in a retracted state, there is a fixed spacing distance between the mounting plate 120 and the rear end surface inside the box body 100; when the temperature control system 200 is in an extended state, the mounting plate 120 is close to the rear end surface inside the box body 100.

[0033] The heat generated by the electrical component 121 is mainly transferred to the mounting plate 120 and the water tank through heat conduction. When the mounting plate 120 is in direct contact with the inner back of the box 100, the heat can be directly transferred to the box 100, and the heat of the electrical component 121 is dissipated through the box 100; when there is a fixed spacing between the mounting plate 120 and the inner back of the box 100, the heat generated by the electrical component 121 cannot be directly dissipated through the box 100. When the temperature control system 200 is in the retracted state, due to the fixed spacing between the mounting plate 120 and the rear end surface of the box 100, the heat generated by the electrical component 121 cannot be directly dissipated through the box 100, resulting in a reduction in the heat dissipation area. Compared with the heat conduction of solids, the thermal conductivity of air is low, the overall heat dissipation of the electrical component 121 is slow, and the water temperature in the water tank is high; due to the forced convection of the circulation component 210, the temperature at the wiring hole is high, which further reduces the possibility of ice formation at the wiring hole. When the temperature control system 200 is in an extended state, the mounting plate 120 is in close contact with the rear end surface of the box body 100, and the heat generated by the electrical component 121 can be directly dissipated through the box body 100, thereby increasing the heat dissipation area. Compared with air heat dissipation (natural convection), the heat conduction speed of solids is fast, which further accelerates the dissipation of heat generated by the electrical component 121.

[0034] As a further solution of this embodiment: the temperature control system 200 also includes a shielding component 220, and the shielding component 220 includes a second rotating shaft 221 and a shielding cloth 222; the second rotating shaft 221 is parallel to the intersection of the rear end face and the top face of the box body 100, and passes through the box body 100; the second rotating shaft 221 is wound around and connected to the shielding cloth 222, and is rotatably connected to the box body 100; when the temperature control system 200 is in a retracted state, the shielding cloth 222 completely covers the electrical component 121 and the water tank; when the temperature control system 200 is in an extended state, the shielding cloth 222 is completely wound around the second rotating shaft 221.

[0035] Furthermore, a snap ring is provided at the contact point between the second rotating shaft 221 and the outer surface of the box body 100 to prevent the second rotating shaft 221 from axial movement.

[0036] The heat generated by the electrical component 121 is mainly transferred to the mounting plate 120 and the water tank by heat conduction, and part of the heat is dissipated by contact with the air. In order to reasonably utilize the dissipated heat, a shielding component 220 can be placed directly in front of the electrical component 121, and the shielding component 220 can be adjusted to cover or not cover the electrical component 121 to decide whether to use this part of the heat. When the temperature control system 200 is in the retracted state, the shielding cloth 222 completely covers the electrical component 121 and the water tank, and part of the heat dissipated by the air flows to the water tank under the covering effect of the shielding cloth 222, thereby further increasing the water temperature in the water tank, and the temperature at the wiring hole also increases accordingly, and the wiring hole is less likely to freeze, realizing the reasonable utilization of this part of the heat. When the temperature control system 200 is in an extended state, the shielding cloth 222 is completely wound around the second rotating shaft 221, the shielding cloth 222 does not cover the electrical component 121, the heat lost by the electrical component 121 through contact with the air is not used, and the shielding component 220 does not affect the normal operation of the electrical component 121 in a high temperature environment.

[0037] As a further solution of this embodiment: a wind shield component 230 is provided at the ventilation holes on the outer surface of the box body 100, and the wind shield component 230 includes a wind shield plate 231, and the wind shield plate 231 is rotatably connected to the box body 100; when the temperature control system 200 is in a retracted state, the wind shield plate 231 fits tightly against the box body 100 and completely covers the ventilation holes of the box body 100; when the temperature control system 200 is in an extended state, the wind shield plate 231 is set at an angle to the box body 100.

[0038] Furthermore, the rotation connection between the wind shield plate 231 and the box body 100 is arranged above the ventilation hole.

[0039] The ventilation holes of the existing distribution box are always kept open so that the outside air can achieve convection with the air inside the box 100, helping the electrical components 121 inside the box 100 to dissipate heat better. The reason why the present invention sets a rotatable windshield 231 at the ventilation hole is that the degree of fit between the windshield 231 and the box 100 determines whether the inside of the box 100 is ventilated. By setting the rotating connection between the windshield 231 and the box 100 above the ventilation hole, the windshield 231 set at an angle can effectively block rain and snow. When the temperature control system 200 is in a retracted state, the wind shield 231 fits tightly against the box 100 and completely covers the ventilation holes of the box 100. At this time, external air cannot enter the box 100 through the ventilation holes, and the air inside the box 100 always remains inside the box 100, so the temperature inside the box 100 can also be preserved; when the temperature control system 200 is in an extended state, the wind shield 231 is set at an angle to the box 100. At this time, the interior of the box 100 is in direct contact with the external environment, and the interior of the box 100 can be ventilated to prevent the internal temperature of the box 100 from being too high.

[0040] As a further solution of this embodiment: it also includes a first rotating shaft 240 and a horizontal rotating shaft 250; the first rotating shaft 240 is parallel to the second rotating shaft 221, passes through the box body 100, and is connected to the box body 100 by rotation; the first rotating shaft 240 is provided with two ends of threads, the threads at the two ends rotate in opposite directions, and are located between the inner surface of the box body 100 and the outer surface of the water tank, and are respectively connected to two moving parts 260, and the two moving parts 260 are respectively fixedly connected to the left pipeline 212 and the right pipeline 213; the horizontal rotating shaft 250 is located in the middle position of the left and right sides of the box body 100, and is connected to the first rotating shaft 240 by bevel gear meshing; the two ends of the horizontal rotating shaft 250 are connected to the box body 100 by rotation, and the horizontal rotating shaft 250 is connected to the mounting plate 120 by threading; the first rotating shaft 240 is connected to the second rotating shaft 221 by transmission; the second rotating shaft 221 is wound with a traction rope 232, and the traction rope 232 is connected to the wind shield 231.

[0041] Furthermore, the first rotating shaft 240 includes three sections of shafts, the left and right sections of the shaft include protrusions, and the middle section of the shaft includes a groove, the protrusions and the grooves can fit tightly together, and the protrusions and the grooves are respectively provided with through holes for bolt connection; a retaining ring is provided at the contact point between the first rotating shaft 240 and the outer surface of the box body 100 to prevent the first rotating shaft 240 from axial movement; a rotating handle 270 is provided at one end of the first rotating shaft 240, and the two are detachably connected; the transmission connection between the first rotating shaft 240 and the second rotating shaft 221 can adopt belt drive, a large diameter pulley is provided on the first rotating shaft 240, and a small diameter pulley is provided on the second rotating shaft 221; the wind shield 231 includes a circular hole, one end of the traction rope 232 is wound around the second rotating shaft 221, and the other end is wound around the circular hole; if there are multiple wind shields, the traction rope 232 can be wound around the circular hole of each wind shield 231 in turn.

[0042] The main purpose of this technical solution is to specifically explain the linkage structure between the left pipeline 212, the right pipeline 213, the mounting plate 120, the shielding component 220, and the windshield component 230, and to achieve the synchronous movement between the above-mentioned technical features through the linkage structure. Thus, when the temperature control system 200 is in the retracted state, the effect of using the heat generated by the electrical component 121 to increase the temperature is the best, so that the integrated power distribution box of the power grid can be used normally outdoors in winter; when the temperature control system 200 is in the extended state, the heat dissipation effect of the heat generated by the electrical component 121 is the best, so that the integrated power distribution box of the power grid can be used normally outdoors in summer. The specific operation is as follows: when the temperature control system 200 is in the retracted state, the left pipeline 212 and the right pipeline 213 are close to the left and right sides of the water tank, the mounting plate 120 and the rear end surface inside the box body 100 have a fixed spacing distance, the shielding cloth 222 completely covers the electrical component 121 and the water tank, and the windshield plate 231 is close to the box body 100. When the temperature control system 200 needs to change from the retracted state to the extended state: the rotating handle 270 is rotated in the opposite direction, the first rotating shaft 240 rotates synchronously with the rotating handle 270, and the two moving parts 260 that are in direct contact with the threads at both ends of the first rotating shaft 240 begin to move synchronously toward the two side surfaces inside the box body 100. Since the left pipeline 212 and the right pipeline 213 are connected to the two moving fixed connections, the left pipeline 212 and the right pipeline 213 also move toward the two side surfaces inside the box body 100 with the two moving parts 260; since the horizontal rotating shaft 250 and the first rotating shaft 240 are meshed with bevel gears, when the first rotating shaft 240 rotates, the horizontal rotating shaft 250 also rotates therewith, and the horizontal rotating shaft 250 threadedly connected to the horizontal rotating shaft 250 The mounting plate 120 also moves toward the rear end surface inside the box body 100 under the action of the spiral transmission; since the first rotating shaft 240 and the second rotating shaft 221 are connected by belt transmission, the rotation of the first rotating shaft 240 will also drive the rotation of the second rotating shaft 221. Since the pulley diameter of the first rotating shaft 240 is large and the pulley diameter of the second rotating shaft 221 is small, the rotation speed of the second rotating shaft 221 is higher than the rotation speed of the first rotating shaft 240. The rotation of the second rotating shaft 221 will drive the shielding cloth 222 and the traction rope 232 wound therewith to wind around the second rotating shaft 221. The wound traction rope 232 will drive the wind shield 231 to rotate around the box body 100, and the angle between the wind shield 231 and the box body 100 will gradually increase. When the temperature control system 200 is in an extended state, the left pipeline 212 and the right pipeline 213 are close to the left and right sides of the interior of the box 100, the mounting plate 120 is close to the rear end surface of the interior of the box 100, the shielding cloth 222 is completely wound around the second rotating shaft 221, and the wind shield 231 is set at an angle to the box 100.

[0043] As a further solution of this embodiment: it also includes an energy storage system 300, which includes a water tank 310, a vacuum pump 320, a connecting pipe 330, and a first exhaust pipeline 340. The water tank 310 is installed on the pipeline of the circulation component 210, and the vacuum pump 320 is placed on the bottom surface of the box body 100. The water tank 310, the vacuum pump 320, and the connecting pipe 330 will not interfere with the normal operation of the temperature control system 200; the water tank 310, the vacuum pump 320, and the connecting pipe 330 are all connected in sequence by the connecting pipe 330; the first exhaust pipeline 340 is arranged around the door frame inside the box body 100, and a plurality of exhaust holes are opened on one side of the first exhaust pipeline 340, which are directly opposite to the door 110.

[0044] Furthermore, the water storage tank 310 can adopt a semicircular ring structure and be arranged in the lower half of the left pipeline 212; the connecting pipe 330 between the components has sufficient margin; and a first column 321 is arranged between the vacuum pump 320 and the inner bottom surface of the box body 100.

[0045] The purpose of setting up the energy storage system 300 of the present invention is to use the energy storage system 300 to absorb part of the heat in the circulation component 210 of the temperature control system 200, and store the absorbed heat, so as to decide whether to use the stored heat according to different working occasions. Its specific working principle is: since the water storage tank 310 is in direct contact with the left pipe 212, the heat of the left pipe 212 and the water inside it is mainly transferred to the water storage tank 310 and the water inside the water storage tank 310 by heat conduction. When the integrated power distribution box of the power grid is working outdoors in winter, ice is easily formed at the door gap, thereby preventing the normal opening and closing of the door 110, and bringing difficulties to the inspection and maintenance work; at this time, the vacuum pump 320 extracts the water vapor vaporized from the water storage tank 310, and transmits it to the first exhaust pipeline 340 through the connecting pipe 330, and discharges the water vapor to the door 110 through the exhaust hole on the first exhaust pipeline 340. Part of the water vapor is blocked by the door 110 and moves to the door gap, and melts the ice at the door gap; when the original water vapor in the water storage tank 310 is removed by the vacuum pump 320, the water vapor vaporized in the water storage tank 310 is removed by the vacuum pump 320. After continuous extraction, the pressure in the water tank 310 continues to decrease. When the pressure drops to a value lower than the saturated vapor pressure of water at the current temperature, the water in the water tank 310 reaches the boiling point and accelerates vaporization. Since the water tank 310 is in direct contact with the left pipe 212, the heat in the left pipe 212 is continuously transferred to the water tank 310, which can ensure that the temperature of the vaporized water vapor is stable. After that, the above operation is repeated to transport the water vapor to the door gap, and the ice at the door gap is continuously melted to prevent the door 110 and the box body 100 from freezing, so that the staff can perform maintenance. At the same time, the reason for using water vapor to melt the ice instead of water is to prevent the low temperature at the door gap from causing the water transported thereto to freeze. Among them, the vacuum pump 320 can be a vacuum pump 320 such as a water ring vacuum pump 320 that can extract water vapor.

[0046] As a further solution of this embodiment: the energy storage system 300 also includes a second exhaust pipeline 350, which is arranged around the inside of the box body 100 close to the ventilation hole and is connected to the vacuum pump 320 through a connecting pipe; a plurality of exhaust holes are opened on one side of the second exhaust pipeline 350, and the exhaust holes are all facing the ventilation holes of the box body 100; the second exhaust pipeline 350 is opened with a groove, and the size of the groove is adapted to the size of the left pipeline 212 and the right pipeline 213.

[0047] Furthermore, valves are provided at the connection points between the first exhaust pipeline 340 and the second exhaust pipeline 350 and the connecting pipe 330 respectively; when water vapor needs to melt ice at the door gap, the valve of the first exhaust pipeline 340 is opened and the valve of the second exhaust pipeline 350 is closed; when ice at the ventilation hole needs to be melted, the valve of the second exhaust pipeline 350 is opened and the valve of the first exhaust pipeline 340 is closed; the second exhaust pipeline 350 can be set to two sections, and a groove is formed between the two sections of the second exhaust pipeline 350. When the two sections of the second exhaust pipeline 350 are connected to the connecting pipe 330, they shall not interfere with the direct contact between the left pipeline 212 and the right pipeline 213 and the inner side of the box body 100; it is also possible to select a single section of the second exhaust pipeline 350 to be connected to the connecting pipe 330.

[0048] When the integrated power distribution box of the present power grid works outdoors in winter, if the outdoor temperature is not so cold, the wind shield 231 can be left at a certain angle to facilitate air circulation inside the box 100; at this time, the ventilation holes are prone to ice formation, thereby blocking the ventilation holes and affecting the air circulation inside the box 100. To solve this problem, the energy storage system 300 of the integrated power distribution box of the present power grid also includes a second exhaust pipeline 350, which uses a vacuum pump 320 to suck out the water vapor after accelerated vaporization in the water storage tank 310 and transports it to the second exhaust pipeline 350 through the connecting pipe 330. The water vapor is transported to the ventilation hole through the exhaust hole of the second exhaust pipeline 350, and the water vapor begins to melt the ice at the ventilation hole to prevent the ice from blocking the ventilation hole, so that the inside of the box 100 can be ventilated normally.

[0049] As a further solution of this embodiment: the energy storage system 300 also includes a water replenishment tank 360, the position of the water replenishment tank 360 is completely higher than the position of the water storage tank 310, and will not interfere with the normal operation of the temperature control system 200; the water replenishment tank 360 is connected to the water storage tank 310, and an electromagnetic valve is provided at the connection between the two, and the water storage tank 310 is installed with a liquid level detection sensor.

[0050] Furthermore, a second column 361 may be provided on the inner bottom surface of the box body 100 for installing the water replenishment tank 360 .

[0051] When the water vapor inside the water tank 310 is discharged by the first exhaust pipe 340 or the second exhaust pipe 350, the water level inside the water tank 310 gradually decreases. In order to ensure that the integrated distribution box of the power grid can melt ice at the door gap or the ventilation hole normally, it is necessary to regularly replenish water to the water tank 310. To this end, the present invention is provided with a replenishing tank 360. When the liquid level in the water tank 310 is lower than the standard value set by the liquid level detection sensor, the liquid level detection sensor sends a signal to the electromagnetic valve and controls the electromagnetic valve to open. At this time, the water in the replenishing tank 360 flows into the water tank 310 due to its own gravity. When the water level in the water tank 310 reaches the standard value set by the liquid level detection sensor, the electromagnetic valve is closed.
