Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, and in particular to a safety monitoring and early warning processing device for a power distribution cabinet. Background Art

[0002] The distribution cabinet is the final equipment of the distribution system. It needs to be monitored for safety when it is in operation, such as monitoring the temperature and humidity inside the distribution cabinet to ensure its stability. At present, the electrical components in the distribution cabinet will inevitably generate heat when working. If the power is too large in a certain period of time, a fault will occur, and further a fire will occur. The heat dissipation structure equipped in the distribution cabinet is not targeted, and it is impossible to dissipate heat in time for local high temperature conditions. In addition, since the distribution cabinet needs to dissipate heat, it will be connected to the outside air. If the air is humid, it will also affect the normal operation of the electrical components in the distribution cabinet. The drying structure set in the distribution cabinet in the prior art will be consumed when the air humidity is appropriate. The drying structure after consumption has limited effect on drying the air when the air is too humid. Summary of the invention

[0018] Compared with the prior art, the beneficial effects of the power distribution cabinet safety monitoring and early warning processing device are:

[0019] 1. With the help of infrared temperature sensors to detect the position where high temperature occurs, the same-direction rotation control component can control each guide shaft to rotate relative to the guide frame, thereby driving the left end of each guide plate to swing up and down. If the power distribution electrical components near the upper side of the equipment bracket have high temperature, the same-direction rotation control component drives the left end of the guide plate to swing upward through the guide shaft, and the wind entering from the strip ventilation slot 2 on the right side of the distribution cabinet is blown to the power distribution electrical components near the upper side of the equipment bracket, so as to dissipate heat in a targeted manner for the power distribution electrical components with high temperature.

[0020] 2. If the cooling and heat dissipation effect is not enough, the air inlet and heat dissipation reinforcement components on the guide plate can blow out more cold air to improve the cooling effect on the power distribution electrical components. The use of targeted heat dissipation solutions can reduce the probability of fire. With the help of fire extinguishers, even if a fire occurs in a high-temperature location, it can be extinguished in time.

[0021] 3. When the air humidity is suitable, the channel opening and closing power assembly drives each rectangular drying channel to move to the left. The left end of the rectangular drying channel is closed by the right side of the distribution cabinet. The channel opening and closing control assembly closes the right end of the rectangular drying channel to prevent the drying bags in the rectangular drying channel from being consumed. When the air is overly humid, the channel opening and closing power assembly drives each rectangular drying channel to move to the right. The channel opening and closing control assembly opens the right end of the rectangular drying channel. The air passing through the air inlet box is dried by the drying bags in the rectangular drying channel and then enters the distribution cabinet from the strip ventilation slot 2 on the right side of the distribution cabinet. This can effectively dry the overly humid air and improve the safety and reliability of the use of the distribution cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] For example, see Figures 1 to 14 , this embodiment provides a technical solution: a power distribution cabinet safety monitoring and early warning processing device, including a power distribution cabinet 1, a smoke sensor 10 and a humidity sensor 11 are respectively installed on the top of the power distribution cabinet 1, and also includes a power distribution equipment installation component 7, a cabinet ventilation follow-up control mechanism 3, an exhaust heat dissipation component 8 and an air intake drying mechanism 6;

[0039] The power distribution equipment installation assembly 7 includes a partition 71 and an equipment bracket 72.

If the infrared temperature sensor 9, the smoke sensor 10 or the humidity sensor 11 detects an abnormal situation in the power distribution cabinet 1, the alarm 12 can be used to remind the patrol personnel to deal with it in time.

[0042] The cabinet ventilation follow-up control mechanism 3 includes a strip ventilation slot 2 310, and a plurality of strip ventilation slots 2 310 are vertically and equidistantly provided in the middle of the left and right sides of the power distribution cabinet 1;

[0043] The exhaust and heat dissipation component 8 is installed in the middle of the left side of the power distribution cabinet 1;

[0044] The exhaust and heat dissipation assembly 8 includes an exhaust and heat dissipation frame 81, an exhaust and heat dissipation fan 82, and a protective mesh plate 83. The exhaust and heat dissipation frame 81 is fixedly connected to the middle part of the left side of the distribution cabinet 1 by screws, and the exhaust and heat dissipation fan 82 is installed in the exhaust and heat dissipation frame 81. The exhaust and heat dissipation fan 82 blows air to the left side, and a protective mesh plate 83 is installed at the left end of the exhaust and heat dissipation frame 81. The protective mesh plate 83 is used to protect the exhaust and heat dissipation fan 82. The exhaust and heat dissipation fan 82 blows air outward, and the air in the distribution cabinet 1 is discharged through the strip ventilation slot 2 310 on the left side of the distribution cabinet 1. The external air enters the distribution cabinet 1 through the strip ventilation slot 2 310 on the right side of the distribution cabinet 1, and the air in the distribution cabinet 1 is exchanged, thereby dissipating heat and cooling the distribution cabinet 1.

[0045] The air inlet drying mechanism 6 includes an air inlet box 61, a rectangular drying channel 66, a drying bag 68, a channel opening and closing control component and a channel opening and closing power component. The air inlet box 61 is arranged in the middle of the right side of the distribution cabinet 1. The left and right ends of the air inlet box 61 are provided with openings. A plurality of rectangular drying channels 66 are arranged vertically and equidistantly in the air inlet box 61. The rectangular drying channels 66 are horizontally slidably connected to the air inlet box 61. A drying bag 68 is respectively arranged in each rectangular drying channel 66. A channel opening and closing control component is respectively installed on the right end of each rectangular drying channel 66. Each rectangular drying channel 66 is connected to the channel opening and closing power component, and the rectangular drying channels 66 are staggered with the strip ventilation slot 2 310 in the middle of the right side of the distribution cabinet 1.

[0046] The air inlet drying mechanism 6 also includes a transverse slide rail 62 and a transverse slide bar 63. The rear side of each rectangular drying channel 66 is fixedly connected to a transverse slide bar 63. Each transverse slide bar 63 is transversely slidably connected to a transverse slide rail 62. The rear side of the transverse slide rail 62 is fixedly installed on the rear side of the air inlet box 61. With the help of the transverse slide rail 62 and the transverse slide bar 63, the rectangular drying channel 66 can stably slide left and right relative to the air inlet box 61.

[0047] The air inlet drying mechanism 6 also includes a mesh box 67. The mesh box 67 is arranged at the bottom of the rectangular drying channel 66. The drying bag 68 is located in the mesh box 67. The mesh box 67 is breathable and allows the drying bag 68 to be stably placed at the bottom of the rectangular drying channel 66. The air in the rectangular drying channel 66 passes through the top of the rectangular drying channel 66.

[0048] The air inlet drying mechanism 6 further includes a filter screen 615 . The filter screen 615 is installed at the right end of the air inlet box 61 . The filter screen 615 can filter the air entering the air inlet box 61 .

[0049] The channel opening and closing power assembly includes a push-pull synchronous rod 64 and a drying control electric telescopic rod 65. The rear side of each rectangular drying channel 66 is fixedly connected to the push-pull synchronous rod 64. The left middle part of the push-pull synchronous rod 64 is fixedly connected to the right end of the drying control electric telescopic rod 65. The left end of the drying control electric telescopic rod 65 is fixedly connected to the right side of the power distribution cabinet 1. The drying control electric telescopic rod 65 extends, pushing the push-pull synchronous rod 64 to move right in the air inlet box 61, thereby driving each rectangular drying channel 66 to move right in the air inlet box 61. The drying control electric telescopic rod 65 shortens, pulling the push-pull synchronous rod 64 to move left in the air inlet box 61, thereby driving each rectangular drying channel 66 to move left in the air inlet box 61.

[0050] The channel opening and closing control component includes a triangular side baffle 69, an opening and closing plate 610, an opening and closing shaft 611, a lower gear 612, an upper gear 613 and a fixed rack 614. Two triangular side baffles 69 are fixedly connected to the front and rear sides of the right end of each rectangular drying channel 66, and two longitudinal opening and closing shafts 611 are rotatably connected to the upper and lower sides of the right end of each rectangular drying channel 66. The two opening and closing shafts 611 are fixedly connected to the two opening and closing plates 610 respectively. The front end of the opening and closing shaft 611 on the upper side of the right end of the rectangular drying channel 66 is fixedly connected to the upper gear 613, and the front end of the opening and closing shaft 611 on the lower side of the right end of the rectangular drying channel 66 is fixedly connected to the lower gear 612. The top of the lower gear 612 is meshed with the bottom of the upper gear 613. A transverse fixed rack 614 is fixedly connected to the position on the front side of the air inlet box 61 corresponding to the upper side of the upper gear 613, and the bottom of the fixed rack 614 is meshed with the top of the upper gear 613.

[0051] When the channel opening and closing power assembly drives each rectangular drying channel 66 to move right in the air inlet box 61, since the upper gear 613 moves right relative to the fixed rack 614, the upper gear 613 rotates counterclockwise, and the upper gear 613 drives the opening and closing plate 610 on the upper right side of the rectangular drying channel 66 to flip upward through the opening and closing shaft 611. Since the upper gear 613 and the lower gear 612 are meshed and connected, the lower gear 612 can be driven to rotate clockwise, and the lower gear 612 drives the opening and closing plate 610 on the lower right side of the rectangular drying channel 66 to flip downward through the opening and closing shaft 611. The two opening and closing plates 610 are opened to open the right end of the rectangular drying channel 66. The two opened opening and closing plates 610 can guide more airflow into the rectangular drying channel 66. A large amount of air passing through the air inlet box 61 will enter the rectangular drying channel 66. The air contacts the drying bag 68 in the rectangular drying channel 66 and is dried. The dried air entering the rectangular drying channel 66 is discharged from the right end.

[0052] When the channel opening and closing power assembly drives each rectangular drying channel 66 to move left in the air inlet box 61, the left end of the rectangular drying channel 66 abuts against the right side of the distribution cabinet 1, so that the left end of the rectangular drying channel 66 is closed, and the upper gear 613 moves left relative to the fixed rack 614, and the upper gear 613 rotates clockwise. The upper gear 613 drives the opening and closing plate 610 on the upper side of the right end of the rectangular drying channel 66 to flip downward through the opening and closing shaft 611. Since the upper gear 613 and the lower gear 612 are meshed and connected, the lower gear 612 can be driven to rotate counterclockwise. The lower gear 612 drives the opening and closing shaft 611 to rotate counterclockwise. The opening and closing plate 610 on the lower right end of the rectangular drying channel 66 is flipped upward, and the two opening and closing plates 610 are moved closer to each other until the right ends of the two opening and closing plates 610 touch each other. The two opening and closing plates 610 cooperate with the two triangular side baffles 69 to close the right end of the rectangular drying channel 66. At this time, the air passing through the air inlet box 61 will not enter the rectangular drying channel 66, and the drying bag 68 in the rectangular drying channel 66 will not be consumed, thereby improving the sealing of the rectangular drying channel 66. A sealing gasket is provided at the left end of the rectangular drying channel 66, and flexible sealing gaskets are provided on the four sides of the opening and closing plate 610.

[0053] When in use, the smoke sensor 10 is used to detect whether there is a fire in the power distribution cabinet 1, and the humidity sensor 11 is used to detect the air humidity in the power distribution cabinet 1. The equipment bracket 72 is vertically equidistantly installed with multiple power distribution electrical components, and the number of power distribution electrical components is the same as the number of infrared temperature sensors 9. The infrared temperature sensor 9 is used to detect whether each power distribution electrical component is high temperature, which is conducive to targeted heat dissipation of the power distribution electrical components with high temperature according to the detection results, thereby improving the safety of the use of the power distribution electrical components in the power distribution cabinet 1;

[0054] The exhaust and heat dissipation component 8 exhausts air outward through the strip ventilation slot 2 310 in the middle of the left side of the power distribution cabinet 1, and the external cold air enters the power distribution cabinet 1 through the strip ventilation slot 2 310 in the middle of the right side of the power distribution cabinet 1 and the air inlet box 61, thereby dissipating heat and cooling the power distribution cabinet 1;

[0055] When the humidity sensor 11 detects that the air humidity in the power distribution cabinet 1 is normal, the channel opening and closing power assembly drives each rectangular drying channel 66 to move leftward. Since the rectangular drying channel 66 is staggered with the strip ventilation slot 2 310 in the middle of the right side of the power distribution cabinet 1, the left end of the rectangular drying channel 66 is closed by the right side of the power distribution cabinet 1. At this time, the channel opening and closing control assembly closes the right end of the rectangular drying channel 66 to prevent the drying bag 68 in the rectangular drying channel 66 from being consumed.

[0056] When the humidity sensor 11 detects that the air in the distribution cabinet 1 is excessively humid, the channel opening and closing power assembly drives each rectangular drying channel 66 to move right, and the left end of the rectangular drying channel 66 is no longer closed by the right side of the distribution cabinet 1. At this time, the channel opening and closing control assembly opens the right end of the rectangular drying channel 66. At this time, the air passing through the air inlet box 61 will pass through the interior of the rectangular drying channel 66 and contact the drying bag 68. The air passing through the air inlet box 61 is dried by the drying bag 68 in the rectangular drying channel 66 and then enters the distribution cabinet 1 from the strip ventilation slot 2 310 on the right side of the distribution cabinet 1, which can effectively dry the excessively humid air and improve the safety and reliability of the use of the distribution cabinet.

[0058] It also includes an emergency switch gate mechanism 2, which includes a wiring longitudinal sliding component, a longitudinal prism 24, a longitudinal sliding cylinder 25, a support plate 26, a reset handwheel 27, a switch gate component, a disconnecting power component and an opening and closing buffer acceleration component.

The front end of the longitudinal sliding cylinder 25 passes through the support plate 26 and is fixedly connected to the reset handwheel 27.

The left ends of multiple insulating gate rods 215 are fixedly connected to the longitudinal sliding cylinder 25 at equal distances in the longitudinal direction. The number of insulating gate rods 215 is selected according to needs, and generally three are used. The right end of each insulating gate rod 215 is movably connected to the left end of the insulating connecting rod 218 through a movable shaft one, and the right end of the insulating connecting rod 218 is movably connected to the middle part of the knife 221 through a movable shaft two. The right end of the knife 221 is movably connected to the top of the internal wiring conductive seat 220 through a movable shaft three. The bottom of the internal wiring conductive seat 220 is fixedly connected to the insulating seat 219, and the insulating seat 219 is fixed to the longitudinal sliding seat plate 22 by bolts.

When the longitudinal slide cylinder 25 rotates clockwise, the right end of the insulating gate rod 215 is driven to swing downward, and the insulating gate rod 215 pulls the knife 221 to the left through the insulating connecting rod 218, so that the gate at the left end of the knife 221 is quickly matched with the conductive gate seat 216 for connection, thereby connecting the external power supply and the power distribution electrical components to complete the closing work, and when the longitudinal slide cylinder 25 rotates counterclockwise, the right end of the insulating gate rod 215 is driven to swing upward, and the insulating gate rod 215 is pushed to the right through the insulating connecting rod 218, so that the left end of the knife 221 leaves the conductive gate seat 216, thereby disconnecting the external power supply and the power distribution electrical components to complete the opening work.

[0061] The opening and closing buffer acceleration assembly includes a rocker arm 28, a telescopic rod 29, a bent frame 210 and a limit compression spring 211. The rear end of the longitudinal prism 24 is fixedly connected to the right end of the rocker arm 28, the left end of the rocker arm 28 is movably connected to the right end of the telescopic rod 29 through a connecting shaft 1, and the left end of the telescopic rod 29 is movably connected to the bent frame 210 through a connecting shaft 2. The bent frame 210 is fixed to the rear side of the distribution cabinet 1, and a limit compression spring 211 is sleeved on the telescopic rod 29, and the two ends of the limit compression spring 211 are respectively connected to the two ends of the telescopic rod 29.

[0062] By means of the reset hand wheel 27, the longitudinal slide tube 25 and the longitudinal prism 24 are rotated clockwise, and the longitudinal prism 24 drives the swing rod 28 to rotate rightward. At this time, the limit compression spring 211 is gradually compressed, and the telescopic rod 29 is gradually shortened. When the telescopic rod 29 and the limit compression spring 211 are shortened to the shortest state, the telescopic rod 29 and the limit compression spring 211 are in the "dead point" state, and the longitudinal slide tube 25 and the longitudinal prism 24 are continued to be rotated clockwise, the limit compression spring 211 is quickly extended and reset, and the telescopic rod 29 is also extended, which can accelerate the longitudinal slide tube 25. 5 and the clockwise rotation speed of the longitudinal prism 24 can speed up the closing speed of the switch gate assembly and reduce the arc sparks during closing. After the closing is completed, the elastic force of the limit compression spring 211 allows the switch gate assembly to maintain a stable closed state. When it is necessary to open the gate, the opening power assembly quickly pushes the swing rod 28 to the left, and the swing rod 28 drives the longitudinal slide tube 25 and the longitudinal prism 24 to rotate counterclockwise. The telescopic rod 29 and the limit compression spring 211 are first shortened, and then quickly extended after passing the "dead point" state, and the switch gate assembly completes the opening work.

[0063] The switch-off power assembly includes a support 212, a switch-off control electric telescopic rod 213, and a top block 214. The support 212 is fixedly connected to the position on the right side of the swing rod 28 on the rear side of the distribution cabinet 1. The left end of the support 212 is fixedly connected to one end of the switch-off control electric telescopic rod 213, and the other end of the switch-off control electric telescopic rod 213 is fixedly connected to the top block 214. Normally, the switch-off control electric telescopic rod 213 is shortened and does not interfere with the movement of the swing rod 28. When the switch-off assembly needs to complete the switch-off work, the switch-off control electric telescopic rod 213 is extended, and the swing rod 28 is pushed to the left through the top block 214. The swing rod 28 drives the longitudinal slide cylinder 25 and the longitudinal prism 24 to rotate counterclockwise, and the switch-off assembly then completes the switch-off work.

[0064] The wiring longitudinal sliding assembly conveniently drives the support plate 26 and the longitudinal sliding cylinder 25 to move forward, so that the switch gate assembly on the longitudinal sliding cylinder 25 extends a part from the front end of the distribution cabinet 1, which is convenient for wiring on the switch gate assembly. The left and right ends of the switch gate assembly are respectively connected to the external power supply and the distribution electrical components in the distribution cabinet 1. The longitudinal sliding cylinder 25 is connected to the longitudinal prism 24 for longitudinal sliding, so that the longitudinal sliding cylinder 25 and the longitudinal prism 24 can rotate synchronously without affecting the forward and backward activities of the wiring longitudinal sliding assembly. By rotating the longitudinal sliding cylinder 25 and the longitudinal prism 24 clockwise with the help of the reset handwheel 27, the switch gate assembly can be The switch is closed to connect the external power supply to the power distribution electrical components in the distribution cabinet 1. The opening and closing buffer acceleration component is used to accelerate the rotation of the longitudinal slide cylinder 25 and the longitudinal prism 24 after rotating through a certain angle, which is conducive to quickly closing or disconnecting the switch gate component and reducing the arc sparks that occur when the switch gate component is closed or disconnected. If the smoke sensor 10 detects a fire in the distribution cabinet 1, the disconnection power component cooperates with the opening and closing buffer acceleration component to rotate the longitudinal slide cylinder 25 and the longitudinal prism 24 counterclockwise to disconnect the switch gate component and reduce the impact on other equipment in the distribution cabinet 1.

[0065] The cabinet ventilation follow-up control mechanism 3 also includes a vertical through slot 36, a ventilation control plate 37, a strip ventilation slot 1 38, a side slide slot 39 and a switch gate linkage assembly.

The ventilation control plate 37 is provided with a strip ventilation slot 1 38 at the position corresponding to the strip ventilation slot 2 310. Two vertical through slots 36 are respectively provided on the left and right sides of the distribution cabinet 1, and each vertical through slot 36 is respectively connected to the rear side of the corresponding side slide slot 39. The switch gate linkage assembly is installed on the rear side of the distribution cabinet 1, and the left and right ends of the top of the switch gate linkage assembly pass through the two vertical through slots 36 respectively and are detachably connected to the rear sides of the two ventilation control plates 37, and the bottom of the switch gate linkage assembly is connected to the rear end of the longitudinal prism 24.

[0066] The switch gate linkage assembly includes a follower gear 31, a follower rack 32, a limit slide 33, a vertical guide rod 34 and a lifting synchronization rod 35.

The end of the lifting synchronization rod 35 can be fixedly connected to the ventilation control panel 37 by screws, or by a clamping method.

[0067] When the longitudinal prism 24 rotates clockwise, it can drive the follower gear 31 to rotate clockwise, and the meshing action of the follower gear 31 and the follower rack 32 drives the vertical guide rod 34 to move up relative to the limit slide 33, thereby driving the two ventilation control plates 37 to move up through the lifting synchronization rod 35. When the longitudinal prism 24 rotates counterclockwise, it can drive the follower gear 31 to rotate counterclockwise, and the meshing action of the follower gear 31 and the follower rack 32 drives the vertical guide rod 34 to move downward relative to the limit slide 33, and the two ventilation control plates 37 can be driven downward through the lifting synchronization rod 35.

[0068] When the longitudinal prism 24 rotates clockwise to allow the switch gate assembly to complete the closing work, the two ventilation control plates 37 are driven to move up in the two side slide grooves 39 through the switch gate linkage assembly. At this time, the strip ventilation slot 1 38 on the ventilation control plate 37 corresponds to the strip ventilation slot 2 310, and the distribution cabinet 1 can complete normal internal ventilation through the strip ventilation slots 2 310 on the left and right sides. When a fire occurs in the distribution cabinet 1, the switch-off power assembly quickly pushes the swing rod 28 to the left, the longitudinal prism 24 rotates counterclockwise, and the switch gate assembly completes the switch-off work. At this time The two ventilation control plates 37 are driven to move downward in the two side slide grooves 39 through the switch gate linkage assembly, and the strip ventilation groove 1 38 on the ventilation control plate 37 is staggered with the strip ventilation groove 2 310. The ventilation control plate 37 blocks the strip ventilation groove 2 310, and the distribution cabinet 1 is in a sealed state. External air is not easy to enter the distribution cabinet 1, which is conducive to rapid fire extinguishing in the distribution cabinet 1. When the switch is closed and the power is turned on, the distribution cabinet 1 can be ventilated with the help of the strip ventilation groove 2 310. When the switch is opened and the power is turned off, the distribution cabinet 1 is closed, which is convenient for rapid fire extinguishing.

[0069] For example 3, please refer to Figures 1 to 14 This embodiment provides a technical solution: a distribution cabinet safety monitoring and early warning processing device. The structure of this embodiment is roughly the same as that of the second embodiment, except that:

[0070] It also includes an air inlet guide and deflector mechanism 4, which includes a guide frame 41, a guide shaft 42, a guide plate 43, a same-direction rotation control component and an air inlet heat dissipation reinforcement component. A guide frame 41 is installed in the middle of the right side of the distribution cabinet 1, and a plurality of longitudinal guide shafts 42 are vertically equidistantly connected to the guide frame 41. The front end of each guide shaft 42 is connected to the same-direction rotation control component, and a guide plate 43 is fixedly connected to each guide shaft 42, and an air inlet heat dissipation reinforcement component is installed on the guide plate 43.

[0071] The same-direction rotation control assembly includes a control gear 44, a vertical slide rail 45, a control rack 46, and a guide control electric telescopic rod 47. The front ends of each guide shaft 42 pass through the front side of the guide frame 41 and are fixedly connected to the control gear 44. The right side of the distribution cabinet 1 is fixedly connected to the vertical slide rail 45. The vertical slide rail 45 is vertically slidably connected to the control rack 46. The control rack 46 is meshed with each control gear 44. The top end of the control rack 46 is fixedly connected to the bottom end of the guide control electric telescopic rod 47. The guide control electric The top end of the movable telescopic rod 47 is installed on the right side of the distribution cabinet 1 through a convex seat, and the guide controls the electric telescopic rod 47 to extend, pushing the control rack 46 to slide downward along the vertical slide rail 45. The meshing action of the control rack 46 and the control gear 44 drives the control gear 44 to rotate clockwise, and the control gear 44 drives the left ends of each guide plate 43 to swing upward synchronously through the guide shaft 42. When the guide controls the electric telescopic rod 47 to shorten, the control gear 44 drives the left ends of each guide plate 43 to swing downward synchronously through the guide shaft 42.

[0072] The air inlet heat dissipation enhancement component includes a flexible branch pipe 48, a nozzle 49, a manifold 410, an air pump 411 and a solenoid valve 412. The guide plate 43 is a hollow structure, and nozzles 49 are equidistantly arranged on one side of the guide plate 43 close to the center of the distribution cabinet 1. The rear end of each guide plate 43 is respectively connected to one end of the flexible branch pipe 48, and the other end of each flexible branch pipe 48 is connected to the manifold 410. The top of the manifold 410 is closed, and the bottom end of the manifold 410 is connected to the outlet of the air pump 411. The air pump 411 is installed at the bottom of the distribution cabinet 1, and the inlet of the air pump 411 extends to the outside of the distribution cabinet 1. A solenoid valve 412 is installed at one end of the manifold 410 close to the air pump 411. Open the solenoid valve 412, the air pump 411 introduces cold air from the outside, and then sends the cold air into the guide plate 43 through the collecting pipe 410 and the flexible branch pipe 48. The cold air in the guide plate 43 is sprayed to the power distribution electrical components with high temperature through the nozzle 49, so as to improve the heat dissipation effect of the power distribution electrical components. Because the guide plate 43 has been facing the power distribution electrical components with high temperature, the nozzle 49 is also aimed at the power distribution electrical components with high temperature at this time. The cold air mentioned above is not absolutely low temperature air, but is only lower in temperature compared to the air in the distribution cabinet 1.

[0073] The same-direction rotation control component can control each guide shaft 42 to rotate relative to the guide frame 41, thereby driving the left end of each guide plate 43 to swing up and down. If the power distribution electrical components near the upper side of the equipment bracket 72 reach high temperature, the same-direction rotation control component drives the left end of the guide plate 43 to swing upward through the guide shaft 42, and the wind entering from the strip ventilation slot 2 310 on the right side of the distribution cabinet 1 is blown toward the power distribution electrical components near the upper side of the equipment bracket 72, so as to dissipate heat in a targeted manner for the power distribution electrical components that reach high temperature. If the cooling and heat dissipation effect is not enough, the air inlet and heat dissipation reinforcement component on the guide plate 43 can blow out more cold air to improve the cooling effect on the power distribution electrical components.

[0074] It also includes a fire extinguisher 5, which is installed at the bottom of the distribution cabinet 1. The outlet of the fire extinguisher 5 is connected to the header 410, and a solenoid valve 2 51 is installed at the outlet of the fire extinguisher 5. The fire extinguisher 5 uses a gas fire extinguisher, such as a carbon dioxide fire extinguisher or a heptafluoropropane gas fire extinguisher. If a fire occurs in a high-temperature distribution electrical appliance component, the solenoid valve 1 412 and the air pump 411 are closed, and the solenoid valve 2 51 is opened. The fire extinguishing medium in the fire extinguisher 5 enters the guide plate 43 through the header 410 and the flexible branch pipe 48, and is then released through the nozzle 49 toward the place where the fire occurs, thereby achieving rapid fire extinguishing.

[0075] It is worth noting that the output ends of the infrared temperature sensor 9, the smoke sensor 10 and the humidity sensor 11 disclosed in the above embodiments are electrically connected to the input end of the external PLC controller, and the connection method between the external PLC controller and the infrared temperature sensor 9, the smoke sensor 10 and the humidity sensor 11 adopts the existing technology.
