Description

Technical Field

[0001] The present invention relates to the technical field of box-type substations, and in particular to an outdoor box-type substation. Background Art

[0002] After the AC power transmission level of 750 kV and above is stepped down, it is sent to the outdoor substation through the high-voltage power grid, and then transmitted to the end user through the outdoor substation. Among them, the outdoor box substation is a prefabricated substation that integrates high-voltage switchgear, transformers, and low-voltage distribution equipment. It is usually installed outdoors and is used to convert the electric energy of the high-voltage power grid into low-voltage electric energy suitable for users.

[0005] However, when the ambient temperature is too high, the cooling effect of the patent on the box-type transformer box will be reduced.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0021] In the description of the present invention, it should be understood that the terms "center", "transverse", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] like Figures 1 to 7 As shown, an outdoor box-type substation of the present invention includes a box-type substation body 1, a heat dissipation component 2 for dissipating heat from the box-type substation body 1, and a cooling component 3 for increasing the heat dissipation effect.

[0023] A temperature detector is also installed on the box-type substation body 1. Ventilation holes are opened on the box-type substation body 1. In daily use, the ventilation holes on the box-type substation body 1 are relied upon to dissipate heat by air convection. When the temperature detector detects that the temperature inside the box exceeds the set value (such as ℃), heat is dissipated through the heat dissipation component 2. Finally, when the temperature detector detects that the temperature inside the box exceeds the set value and the temperature continues to not drop, the cooling component 3 is started to enhance the cooling effect, effectively extending the life of the equipment and reducing the risk of failure.

[0024] It should be noted that outdoor box-type substations are widely used in cities, and their installation environment is often faced with typical urban interference factors such as dust accumulation and bird activities. Targeted measures are needed to ensure operational safety. The heat dissipation component 2 described in this application includes: a fan 21 fixedly installed on the box-type outdoor substation, a protective net 23 fixedly installed on the air inlet end of the fan 21, and a filter 22 fixedly installed on the air outlet end of the fan 21. The fan 21 is set in multiple groups according to usage needs to improve the heat dissipation effect of the box-type substation body 1. The protective net 23 can prevent hard objects from hitting the fan 21 and causing damage to the fan 21, affecting the use effect of the box-type substation body 1, and the filter 22 filters the gas blown by the fan 21 into the box-type substation body 1 to prevent dust in the gas from being sent into the box-type substation body 1, causing the temperature detector and humidity probe to be covered with dust, which may distort the monitoring data and cause the cooling system to misjudge or delay response.

[0025] The protective net 23 is a metal net, which is connected to the fan 21 through bolts. The filter 22 is an activated carbon filter 22, which is also connected to the fan 21 through bolts.

[0026] In addition, the cooling component 3 includes: a fixing frame 32 fixedly mounted on the box-type substation body 1; a pipeline 321 is fixedly mounted on the fixing frame 32, a flange of the water inlet end of the pipeline 321 is connected to a joint 322, a flange of the joint 322 is connected to a water inlet pipe 323, the water inlet pipe 323 is connected to a pump body, the pump body is connected to a water tank, the water tank is connected to the pipeline 321, when the ambient temperature is too high and the temperature in the box-type substation body 1 continues to not drop, the liquid in the water tank is pumped into the water tank through the water inlet pipe 323, the joint 322, and the pipeline 321. The liquid enters the box-type substation body 1 and exchanges heat with the temperature inside the outdoor box-type substation body 1 through the circulation of the liquid in the water channel, thereby realizing the cooling of the box-type outdoor substation. After the liquid continues to exchange heat, the temperature will gradually rise. At this time, the "heat absorption capacity" of the liquid becomes worse and the heat dissipation efficiency becomes lower and lower. Therefore, a cooler is installed on the water tank to cool the liquid to ensure the cooling of the liquid. The pipeline 321 is serpentine and coiled on the fixed frame 32, which can extend the duration of the water in the box-type substation body 1 and ensure the heat exchange effect between the water and the box-type substation body 1.

[0027] The cooling assembly 3 also includes: a fan blade 31 rotatably mounted on the box-type substation body 1, an inclined plate 311 fixedly mounted on the fan blade 31, and a knocking piece 312 fixedly mounted on the inclined plate 311. The natural wind drives the fan blade 31 to rotate, so that the fan blade 31 drives the inclined plate 311 to rotate. Due to the oblique setting of the inclined plate 311, the inclined plate 311 drives the knocking piece 312 to knock on the top of the box-type substation body 1 as the fan blade 31 rotates. The sound generated during the knocking will alarm the birds on the box-type substation body 1, thereby driving away the birds. A speed sensor is installed on the fan blade 31. When the fan blade 31 does not rotate or the speed is low, the water pump is turned on in advance to drive the water circulation, so as to dissipate heat in advance inside the box-type substation body 1, thereby preventing the box-type substation body 1 from cooling down after the temperature rises, and reducing failures caused by temperature rise.

[0028] In addition, a rotating rod 315 is rotatably installed on the water inlet pipe 323, and a rotating plate 3151 is fixedly installed on the rotating rod 315. An air guide plate 24 is rotatably installed on the filter 22, and a push rod 317 is rotatably installed on the air guide plate 24. A movable block 316 is fixedly installed on the push rod 317. A limiting groove 3161 is provided on the movable block 316, and a limiting rod 3153 is slidably connected to the limiting groove 3161. The limiting rod 3153 is fixedly installed on the water pipe. A guide groove 3162 is provided on the movable block 316, and a guide block 3152 is slidably connected to the guide groove 3162. The guide block 3152 is fixedly installed on the rotating rod 315.

[0029] When the water passes through the water inlet pipe 323, the rotating plate 3151 drives the rotating rod 315 to rotate. When the rotating rod 315 rotates, the guide block 3152 slides in the guide groove 3162. The guide groove 3162 is composed of two sets of thread grooves coaxially opened on the movable block 316, with the same pitch, opposite screw direction, and interconnected. When the guide block 3152 slides in the guide groove 3162, the movable block 316 slides back and forth on the limit rod 3153 through the limit groove 3161, which is used to adjust the movement of the movable block 316. The movement is limited, so that the movable block 316 moves back and forth on the rotating rod 315, and the push rod 317 drives the wind guide plate 24 to swing, so that the air flow blown by the fan 21 into the outdoor box-type substation body 1 is blown toward the bottom of the outdoor box-type substation body 1 under the action of the wind guide plate 24, thereby expanding the range of the air flow blown by the fan 21 into the outdoor box-type substation body 1, and realizing direct cooling of the transformer, switchgear, reactive compensation device and control unit and other equipment in the outdoor box-type substation body 1.

[0030] In general, the present application satisfies the heat dissipation of the outdoor box-type substation body 1 under high temperature conditions through the heat dissipation component 2, and cools down the outdoor box-type substation body 1 whose temperature continues to rise through the cooling component 3, thereby enhancing the cooling effect on the outdoor box-type substation body 1, and at the same time drives the wind guide plate 24 to swing, so that the air flow blows directly to the electrical equipment in the outdoor box-type substation body 1, thereby improving the cooling effect on the outdoor box-type substation body 1.

[0031] It should be supplemented with respect to the above that an expansion block 3231 is fixedly mounted on the water inlet pipe 323 , a connecting rod 313 is fixedly mounted on the fan blade 31 , a transmission assembly 314 is provided on the connecting rod 313 , and the transmission assembly 314 connects the transmission rod and the connecting rod 313 .

[0032] When there is no natural wind or the natural wind is weak in the environment, water is pumped through the water inlet pipe 323 by the pump body, driving the rotating plate 3151 to rotate the rotating rod 315. At this time, the rotating rod 315 drives the connecting rod 313 to rotate through the transmission component 314, thereby causing the fan blade 31 to rotate continuously, and drives the knocking piece 312 to knock continuously to drive the birds away. At the same time, in order to prevent the natural wind from blowing the fan blade 31, the rotating plate 3151 is driven to rotate in the opposite direction. The connecting rod 313 is fixedly installed with a connecting piece 3131, and the rotating rod 315 is fixedly installed with an inner Toothed ratchet 3154; the transmission assembly 314 is composed of: a connecting sleeve 3141 rotatably mounted on the internally toothed ratchet 3154, a fixed shaft 3142 fixedly mounted on the connecting sleeve 3141, a spring 3143 fixedly mounted on the fixed shaft 3142, and a pawl 3144 fixedly mounted on the spring 3143. The pawl 3144 is rotatably mounted on the fixed shaft 3142, and the connecting rod 313 is inserted into the interior of the connecting sleeve 3141 through the connecting piece 3131 to achieve connection.

[0033] When the rotating plate 3151 rotates, it drives the inner-toothed ratchet 3154 to rotate. At this time, the tip of the pawl 3144 will be blocked by the vertical surface of the teeth and cannot move, thereby jamming the inner-toothed ratchet 3154. At this time, the rotating plate 3151 drives the rotating rod 315 to rotate through the connecting sleeve 3141, thereby driving the connecting rod 313 to rotate, thereby causing the fan blade 31 to rotate, driving the knocking piece 312 to continuously knock to ensure the bird-repelling effect.

[0034] When the fan blade 31 rotates, the tip of the pawl 3144 can slide and lift along the inclined surface on the teeth of the internal tooth ratchet 3154, and will not drive the connecting piece 3131 and the connecting rod 313 to rotate through the connecting sleeve 3141, so that the internal tooth ratchet 3154 can rotate freely without getting stuck; only when the natural wind blows the fan blade 31 to rotate in the same direction as the rotation direction of the rotating rod 315, the fan blade 31 drives the rotating plate 3151 to rotate, and the rotating plate 3151 disturbs the liquid in the water inlet pipe 323, thereby preventing the liquid in the water inlet pipe 323 from settling and clogging the water inlet pipe 323.

[0035] Finally, when the staff inspects the box-type substation body 1, they first observe whether the fan blade 31 is rotating and the rotation state (the natural wind blows the fan blade 31 with irregular rotation direction and time), and combine the current ambient temperature feedback from the temperature detector to judge whether the cooling component 3 is working properly. For example, if the current ambient temperature is low, the fan blade 31 is rotated only by the natural wind. If the fan blade 31 does not rotate, it indicates that the fan blade 31 has a mechanical failure. When the current ambient temperature is high, the water flow drives the rotating plate 3151 to make the fan blade 31 rotate continuously. At this time, the fan blade 31 rotates continuously and regularly. Rotation. When the temperature of the water in the water inlet pipe 323 is too high, the expansion block 3231 expands due to heat (the material of the expansion piece is preferably rubber) and blocks the rotation of the rotating plate 3151, thereby stopping the movement of the rotating rod 315 and the fan blade 31. At this time, it indicates that the cooler has a refrigeration failure, which is convenient for manual observation to directly determine the cause of the failure, and the maintenance speed is fast, ensuring the use effect of the outdoor box-type substation body 1; in general, birds are driven away by the rotation of the fan blade 31, and the cause of the failure of the cooling component 3 is determined by judging the rotation of the fan blade 31, which is convenient for manual maintenance.
