Description

Technical Field

[0001] This invention relates to the field of transformer cabinets, specifically a corrosion-resistant and leakage-proof transformer cabinet based on a substation. Background Technology

[0002] Substations are key facilities in power systems used to transform voltage, distribute electrical energy, and control the direction of power flow. They use a series of electrical devices to step up, transmit, step down, and distribute the electrical energy generated by power plants, ultimately delivering it safely and reliably to the user end.

[0003] Patent CN215912385U discloses a drawer-type substation cabinet. Specifically, the patent discloses a technical solution in which "the drawer-type substation cabinet includes a cabinet body, a sliding mechanism, and a frequency converter. The mounting bracket is installed on a slide rail and slides along the slide rail. The frequency converter is detachably installed on the mounting bracket. The frequency converter partially extends into or fully extends out of the receiving cavity as the mounting bracket slides. A support frame is set on the outside of the cabinet body and is used to support the frequency converter extending out of the receiving cavity." This achieves the technical effect that "when it is necessary to remove the frequency converter, the mounting bracket can be pulled out from the receiving cavity, and the frequency converter can be removed from the mounting bracket, making the disassembly process convenient."

[0004] Electrical components in substation cabinets are often quickly assembled and disassembled using guide rails. However, after a period of use, the guide rails need to be lubricated, otherwise they will jam. Currently, manual lubrication is used to ensure the normal operation of the guide rails in the substation cabinet. However, manual lubrication is easy to forget, and lubrication when jamming occurs will affect the disassembly and maintenance of the substation cabinet. Summary of the Invention

The substation assembly includes: a substation cabinet body coated with epoxy anti-corrosion paint; and a cabinet door mounted on one side of the front end of the substation cabinet body via a hinge. The triggering assembly includes: a trigger plate disposed on the front side of the transformer cabinet and the rear side of the cabinet door respectively; a reset rod fixed to the rear end of the trigger plate; and a pressing plate fixed to the end of the reset rod. The lubrication assembly includes: a conveying support rod fixed to the inner wall of the transformer cabinet; a lubricating oil outlet nozzle fixed to one side of the conveying support rod; a conveying pipe fixed above the conveying support rod; and a transfer chamber fixed to the end of the conveying pipe, wherein the extrusion plate slides inside the transfer chamber, and the conveying pipe is located on the rear side of the left and right sides of the transfer chamber.

[0007] As a further embodiment of the present invention, the lubrication assembly further includes: a lubricating oil storage tank fixed to the top of the substation cabinet; and a metering pump fixed between the lubricating oil storage tank and the transfer compartment via a pipeline.

[0008] As a further embodiment of the present invention, the triggering component further includes a reset spring fixed between the extrusion plate and the transfer chamber, the reset spring being sleeved on the outside of the reset rod, and a sealing ring being provided at the connection between the reset rod and the transfer chamber.

[0010] As a further embodiment of the present invention: the output direction of the lubricating oil outlet nozzle is toward the connecting guide rail, and the connecting guide rail is used for sliding installation of electrical components.

[0011] As a further embodiment of the present invention, the transformer cabinet assembly further includes: a fixed support rod welded to the top of the transformer cabinet; a rain shelter fixed to the top of the fixed support rod; and a leakage current protection device installed at the bottom of the transformer cabinet by external bolts.

[0012] As a further embodiment of the present invention: the heat dissipation assembly includes: an air intake chamber fixed to the lower part of the inner wall of the transformer cabinet; an exhaust fan fixedly installed inside the air intake chamber by external bolts; and an interception mesh plate disposed on one side of the exhaust fan.

[0013] As a further embodiment of the present invention, the heat dissipation assembly further includes: an exhaust hood fixed to the upper part of the inside of the transformer cabinet; an internal mesh plate welded to the bottom of the exhaust hood; an exhaust pipe fixed to the top of the exhaust hood; and an exhaust chamber fixed to the end of the exhaust pipe.

[0015] As a further embodiment of the present invention, the heat dissipation assembly further includes a flow cavity formed in the inner wall of the exhaust hood, wherein the exhaust hood is tightly fitted to the outside of the transfer chamber.

[0016] Compared with the prior art, the beneficial effects of the present invention include: 1. The trigger component can contact the trigger plate when the cabinet door is closed, thereby driving the extrusion plate to move through the reset rod, squeezing out the lubricating oil in the transfer chamber, so that the lubricating oil is sprayed out through the lubricating oil nozzle to lubricate the connecting guide rail. The lubrication work is done between each opening and closing of the cabinet door, and the connecting guide rail does not need to be manually lubricated by maintenance personnel. 2.

Through the heat dissipation components, the combined action of the exhaust fan and the induced draft fan can achieve forced airflow in the substation cabinet, thereby achieving heat dissipation and cooling of the substation cabinet. When the hot air is discharged, it can enter the flow cavity between the exhaust hood and the transfer chamber, thereby heating the lubricating oil in the transfer chamber and preventing the lubricating oil in the transfer chamber from solidifying in a low-temperature environment, which would affect the normal spraying of the lubricating oil.

[0019] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0020] An embodiment of the present invention is illustrated in conjunction with the accompanying drawings.

[0021] Example 1: Please see Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a corrosion-resistant and leakage-proof substation cabinet based on a substation, including a substation cabinet assembly 1; a lubrication assembly 2 for lubrication; a triggering assembly 3 for triggering the lubrication action; and a heat dissipation assembly 4 for dissipating heat from the substation cabinet assembly 1. The substation assembly 1 includes: a substation cabinet 101 with an epoxy anti-corrosion paint coating on its surface; and a cabinet door 104 that is hinged and installed on one side of the front end of the substation cabinet 101. Trigger assembly 3 includes: a trigger plate 301 disposed on the front side of the transformer cabinet 101 and the rear side of the cabinet door 104 respectively; a reset rod 302 fixed to the rear end of the trigger plate 301; and a pressing plate 304 fixed to the end of the reset rod 302. The lubrication assembly 2 includes: a conveying support rod 201 fixed to the inner wall of the transformer cabinet 101; a lubricating oil outlet nozzle 202 fixed to one side of the conveying support rod 201; a conveying pipe 203 fixed above the conveying support rod 201; and a transfer chamber 206 fixed to the end of the conveying pipe 203. The extrusion plate 304 slides inside the transfer chamber 206, and the conveying pipe 203 is located on the rear side of the left and right sides of the transfer chamber 206.

[0022] Furthermore, the lubrication assembly 2 also includes: a lubricating oil storage tank 204 fixed to the top of the transformer cabinet 101; and a metering pump 205 fixed between the lubricating oil storage tank 204 and the transfer compartment 206 via a pipeline.

[0023] It should be noted that the metering pump 205 is used to measure the amount of lubricating oil passing between the lubricating oil storage tank 204 and the transfer chamber 206. The metering pump 205 is preset so that each time the metering pump 205 is turned on, the lubricating oil in the lubricating oil storage tank 204 flows into the transfer chamber 206 in a fixed amount, and the amount of lubricating oil is just enough to meet the lubrication effect.

[0024] Furthermore, the triggering component 3 also includes a reset spring 305 fixed between the extrusion plate 304 and the transfer chamber 206. The reset spring 305 is sleeved on the outside of the reset rod 302, and a sealing ring 303 is provided at the connection between the reset rod 302 and the transfer chamber 206.

[0025] It should be noted that the sealing ring 303 is used to seal the connection between the reset rod 302 and the transfer chamber 206. Under the action of the reset spring 305, the reset spring 305 can be reset outward, thereby driving the extrusion plate 304 to reset, thus satisfying the next movement of the extrusion plate 304.

[0026] Furthermore, the substation assembly 1 also includes: a device mounting bracket 105 welded inside the substation cabinet 101; and a component mounted on the front end of the device mounting bracket 105 by external bolts.

[0027] It should be noted that multiple sets of device mounting brackets 105 are provided to accommodate the installation of electrical components.

[0028] Furthermore, the output direction of the lubricating oil outlet nozzle 202 is toward the connecting guide rail 106, which is used for sliding installation of electrical components.

[0029] It should be noted that the electrical components include transformers, circuit breakers, disconnect switches, etc. required by the substation cabinet. The device mounting bracket 105 and the rear end of the substation cabinet body 101 are reserved with a certain space to allow for the placement of cables.

[0030] In this embodiment, when the cabinet door 104 is closed, it can come into contact with the trigger plate 301, thereby driving the extrusion plate 304 to move through the reset rod 302, squeezing out the lubricating oil in the transfer chamber 206, so that the lubricating oil is sprayed out through the lubricating oil outlet nozzle 202 to lubricate the connecting guide rail 106. The lubrication work is done between each opening and closing of the cabinet door 104, and the lubrication work of the connecting guide rail 106 does not require maintenance personnel to manually perform the lubrication work. When the metering pump 205 of the lubrication assembly 2 is working, it delivers a metered amount of lubricating oil from the lubricating oil storage tank 204 to the transfer chamber 206 to replenish the lubricating oil in the transfer chamber 206, thereby satisfying the lubrication work of the lubricating oil flowing out of the nozzle 202 to the connecting guide rail 106.

[0031] Example 2: Please see Figures 1-4 This is the second embodiment of the present invention, which provides a corrosion-resistant and leakage-proof substation cabinet based on a substation.

[0032] Furthermore, the transformer cabinet assembly 1 also includes: a fixed support rod 103 welded to the top of the transformer cabinet body 101; a rain shelter 102 fixed to the top of the fixed support rod 103; and a residual current device 107 installed at the bottom of the transformer cabinet body 101 by external bolts.

[0033] It should be noted that the residual current device 107 is in contact with the housing of the transformer cabinet 101. Once the transformer cabinet 101 leaks current, the residual current device 107 can detect the current passing through. At this time, the residual current device 107 can cut off the transformer cabinet 101, which plays a certain protective role for the transformer cabinet 101. The size of the rain shelter 102 is larger than the top size of the transformer cabinet 101, which can play a certain rain shelter effect. The top height of the rain shelter 102 is relatively high, which can prevent rainwater from accumulating.

[0034] Furthermore, the heat dissipation component 4 includes: an air intake chamber 402 fixed to the lower part of the inner wall of the transformer cabinet 101; an exhaust fan 401 fixedly installed inside the air intake chamber 402 by external bolts; and an interception mesh plate 403 disposed on one side of the exhaust fan 401.

[0035] It should be noted that the exhaust fan 401 can bring external airflow into the interior of the transformer cabinet 101, forcing air circulation inside the transformer cabinet 101, while the interception mesh plate 403 is used to intercept large particulate impurities such as dust in the external air.

[0036] Furthermore, the heat dissipation assembly 4 also includes: an exhaust hood 404 fixed inside the upper part of the transformer cabinet 101; an internal mesh plate 409 welded to the bottom of the exhaust hood 404; an exhaust pipe 405 fixed to the top of the exhaust hood 404; and an exhaust chamber 407 fixed to the end of the exhaust pipe 405.

[0037] It should be noted that the exhaust hood 404 is used to draw in the air inside the substation cabinet 101 and discharge it to the outside through the exhaust chamber 407 at the end of the exhaust pipe 405, so as to achieve rapid heat dissipation and cooling of the substation cabinet 101 in conjunction with the exhaust fan 401.

[0038] Furthermore, the exhaust chamber 407 is embedded in the upper left side of the transformer cabinet 101. An exhaust fan 408 is fixedly installed inside the exhaust chamber 407 by external bolts, and a protective mesh plate 406 is provided on one side of the exhaust fan 408.

[0039] It should be noted that after the exhaust fan 408 is started, the exhaust fan 408 can draw the air inside the transformer cabinet 101 into the exhaust hood 404, and the built-in mesh plate 409 at the bottom of the exhaust hood 404 can intercept large particles of impurities such as dust.

[0040] Furthermore, the heat dissipation component 4 also includes a flow cavity 410 formed on the inner wall of the exhaust hood 404, and the exhaust hood 404 is tightly fitted to the outside of the transfer chamber 206.

[0041] It should be noted that after the hot air rises and enters the interior of the exhaust hood 404, it can enter the flow cavity 410 between the exhaust hood 404 and the transfer chamber 206. The hot air heats up the lubricating oil in the transfer chamber 206, preventing the lubricating oil in the transfer chamber 206 from solidifying in a low-temperature environment, which would affect the normal spraying of the lubricating oil.

[0042] In this embodiment, the heat dissipation component 4, through the coordinated action of the induced draft fan 401 and the exhaust fan 408, enables forced airflow to the substation cabinet 101, thereby achieving heat dissipation and cooling of the substation cabinet 101. When the hot air is exhausted, it can enter the flow cavity 410 between the exhaust hood 404 and the transfer chamber 206, thereby heating the lubricating oil in the transfer chamber 206 and preventing the lubricating oil in the transfer chamber 206 from solidifying in a low-temperature environment, which would affect the normal spraying of the lubricating oil.

[0043] Working principle: When maintenance personnel open cabinet door 104, cabinet door 104 rotates forward. At this time, cabinet door 104 and trigger plate 301 move away from each other, and trigger plate 301 loses external force. The return spring 305 retracts outward to reset, thereby driving the pressing plate 304 to move forward, which in turn causes trigger plate 301 to move forward. At this time, metering pump 205 works, which quantitatively delivers lubricating oil from lubricating oil storage tank 204 to the transfer chamber 206, replenishing the lubricating oil in the transfer chamber 206. The lubricating oil flows into the transfer chamber 206, with the amount just enough to achieve the desired lubrication effect. After maintenance is completed, when the cabinet door 104 is closed, the door 104 presses against the trigger plate 301. The trigger plate 301, via the reset rod 302, moves the pressing plate 304 backward. Since the lubricating oil exists between the pressing plate 304 and the back plate of the transfer chamber 206, as the pressing plate 304 moves, the gap between it and the transfer chamber 206 decreases. Under the pressure of the pressing plate 304, the lubricating oil level rises, allowing it to enter the delivery pipe 203. Lubricating oil can be sprayed outward through the lubricating oil outlet nozzle 202 to replenish the lubricating oil in the connecting guide rail 106 located between the lubricating oil outlet nozzles 202. When the substation cabinet 101 is working normally, after the exhaust fan 408 is started, the exhaust fan 408 can draw the air inside the substation cabinet 101 into the exhaust hood 404. The built-in mesh plate 409 at the bottom of the exhaust hood 404 can intercept large particles of impurities such as dust. After the hot air rises and enters the interior of the exhaust hood 404, it can enter the flow channel between the exhaust hood 404 and the transfer chamber 206. Inside the ventilation cavity 410, hot air is used to heat the lubricating oil in the transfer chamber 206 to prevent the lubricating oil in the transfer chamber 206 from solidifying in a low-temperature environment, which would affect the normal spraying of the lubricating oil. At the same time, the exhaust fan 401 can bring external airflow into the transformer cabinet 101, forcibly enabling air circulation inside the transformer cabinet 101. The interception mesh plate 403 is used to intercept large particulate impurities such as dust in the external air. The synergistic effect of the exhaust fan 401 and the exhaust fan 408 achieves forced airflow in the transformer cabinet 101.

[0044] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
