Energy-saving transformer with online monitoring and intelligent voltage regulation

Abstract

This invention discloses an energy-saving transformer with online monitoring and intelligent voltage regulation, relating to the field of transformer technology. The transformer support is equipped with a fire-extinguishing and cooling component. A ring-shaped storage box is slidably fitted onto the outer side of the top support plate. Fire-resistant folding curtains are evenly bonded between adjacent intermediate rings. First electromagnets are installed on both sides of the ring-shaped storage box at positions corresponding to the stress-bearing iron plates. A fire extinguishing bag is bonded inside a thin spring plate. Connecting plates are bonded to the top and bottom of the fire extinguishing bag near the bottom and top plates, respectively. In this invention, if the transformer temperature is too high, the hot-melt frame softens and cannot support the counterweight junction box, causing the wiring conduit and wiring plug to separate. Both the first and second electromagnets will be de-energized. The fire-resistant folding curtain unfolds under the pull of the counterweight ring, and the fire-extinguishing dry powder in the fire extinguishing bag rapidly diffuses and sprays onto the outside of the transformer. The fire-extinguishing dry powder covers the outside of the transformer, quickly extinguishing the fire. Furthermore, the fire-resistant folding curtain isolates the area, reducing air entry and accelerating fire extinguishing.

Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to an energy-saving transformer with online monitoring and intelligent voltage regulation. Background Technology

[0002] Intelligent transformers are intelligent upgrades of traditional power equipment. By integrating sensors, communication modules, and intelligent control technologies, they enable real-time monitoring, dynamic adjustment, and remote management of power transmission. Common types include intelligent dry-type transformers and intelligent oil-immersed transformers.

[0003] The patent application number CN202111229296.0 mentions "an intelligent dry-type transformer that can dissipate heat based on the Internet of Things". It uses a temperature sensor matched with a controller to drive a micro high-speed motor to drive the heat dissipation components for front and rear ventilation and heat dissipation, thus completing intelligent heat dissipation control. Then, through a forward and reverse motor, an electric push rod and a threaded rod and a threaded sleeve, the folding door panel is opened and the left and right sides of the card cover are opened. The heat dissipation components are used to complete relative air blowing, and the stepped through slots on both sides exhaust heat dissipation. This dry-type transformer can be used as an open type or a closed type, and has a wide range of applications.

[0012] According to the above technical solution, a monitoring and control box is installed on one side of the top surface of the top support plate.

[0015] According to the above technical solution, the input terminal of the temperature sensor is electrically connected to the input terminal of the monitoring and control box, and the input terminal of the electric control valve is electrically connected to the output terminal of the monitoring and control box.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The transformer is equipped with fire extinguishing and cooling components. The transformer continues to heat up and the temperature exceeds the safe range, causing a fire. At this time, the transformer temperature is too high, the hot melt frame softens and cannot support the counterweight junction box, the wiring pipe and wiring plug separate, and both the first electromagnet and the second electromagnet will be de-energized. The de-energization of the first electromagnet causes the stressed iron plate to separate from the first electromagnet. The fire-resistant folding curtain unfolds under the pull of the counterweight ring, enclosing the transformer inside the fire-resistant folding curtain. When the thin spring plate unfolds, it pushes the bottom plate and top plate away from each other. The docking plate is pushed by the bottom plate and top plate, tearing the fire extinguishing bag along the tear slit. When the thin spring plate returns to a vertical flat plate, its restoring force will push the fire extinguishing dry powder in the fire extinguishing bag to spread rapidly and spray it to the outside of the transformer. The fire extinguishing dry powder covers the outside of the transformer, extinguishing the fire quickly. And through the isolation of the fire-resistant folding curtain, the air entering is reduced, accelerating the fire extinguishing. When the second electromagnet is de-energized, it will no longer attract the horizontal plate. Under the pushing action of the lifting spring, the annular storage box rises along the limit stop, separating the fixed terminal and the movable terminal, disconnecting the wiring, and preventing the power supply from continuing to be connected and causing more serious problems. The de-energization of the first and second electromagnets can also be manually controlled remotely through the monitoring and control box. If the monitoring and control box fails due to high temperature and circuit failure, it can also be completed by heat melting the aforementioned hot melt frame and wiring pipe. This double protection makes it safer and more reliable. Moreover, the component is small in size, easy to realize the fire extinguishing power-off operation, and more convenient to use.

[0017] 2. An auxiliary cooling component is provided. After the intelligent transformer starts working, air enters the blower from above and flows through the fixed air ducts on both sides. Then, the air is sprayed out along the cooling air holes of the rotating slide to cool the transformer after it starts. If the ambient temperature is not high, the rotating slide can be stored in the fixed air duct to reduce the space it occupies and facilitate maintenance and repair operations by the operators. If the transformer temperature rises continuously and exceeds the normal operating temperature in a short period of time, the temperature sensor detects the abnormal temperature rise. Then, through the monitoring and control box, the electric control valve is activated, the control tube is opened, and the internal connection between the carbon dioxide cylinder and the fixed air duct is established. The compressed carbon dioxide inside the carbon dioxide cylinder will be sprayed out to the outside of the transformer through the cooling air vent. When the liquid carbon dioxide is sprayed out of the carbon dioxide cylinder, it expands in volume and absorbs heat. The dry and cold carbon dioxide is blown towards the transformer and cools it down quickly, preventing the transformer from catching fire and ensuring its safety. The auxiliary cooling components can cool the transformer during use and quickly cool it down in case of abnormal overheating, while the fire extinguishing cooling components can quickly isolate and extinguish the fire if the temperature is too high and causes a fire. With multiple protections, the transformer can be guaranteed to be safe and reliable at all stages of use. Attached Figure Description

[0025] The bottom of the transformer bracket 1 is equipped with an auxiliary cooling component 4. The auxiliary cooling component 4 includes a support base box 401, a ventilation hole 402, a blower 403, a blower sleeve 404, a fixed air duct 405, a bottom slide cylinder 406, a rotating slide cylinder 407, a connecting cloth cylinder 408, a cooling air hole 409, a vertical clamping plate 410, an internally threaded pipe 411, a support screw 412, a positioning through hole 413, a maintenance plate 414, a control pipe 415, an electric control valve 416, a carbon dioxide cylinder 417, and a temperature sensor 418.

[0027] The working principle and usage process of this invention are as follows: A fixed terminal post 301 is passed through the top of the transformer bracket 1 and a top support plate 302 is installed. An annular storage box 303 is sleeved on the top of the top support plate 302. A limit stop 325 fits against the inner two ends of the annular storage box 303. The two ends of the horizontal plate 314 are respectively attached to the top of two lifting springs 319. The lifting springs 319 are made of stainless steel and will not be affected by magnetic attraction. The power connection lines of the first electromagnet 308 and the second electromagnet 318 are connected to the wiring plug 313. The wiring plug 313 is connected to the wiring tube 312. The counterweight wiring box 311 is connected to the external power supply. The second electromagnet 318 attracts the horizontal plate 314 to move down, the lifting springs 319 retract, and the fixed terminal post 301 and the movable terminal post 316 are snapped together. Push the counterweight ring 306 upwards to fold the fire-resistant folding curtain 305 until the stressed iron plate 307 is attracted and fixed by the first electromagnet 308. The intermediate rings 304 move closer to each other, and the thin spring plate 328 is bent by the bottom end of the pressing base plate 326. Open the installation door 317, and attach the fire extinguishing bag 329 to the concave part of the bent thin spring plate 328. Then, attach the docking plate 331 to the adjacent bottom plate 326 and top plate 327 respectively, and place the intelligent transformer. After completing the wiring, before powering on, pull the rotating slide 407 inside the fixed air duct 405 until the connecting cloth tube 408 between the rotating slide 407 and the bottom slide 406 is at the end of the fixed air duct 405. Rotate the rotating slide 407 90° at the connection between the rotating slide 407 and the bottom slide 406, unfold the connecting cloth tube 408, rotate the support screw 412 inside the internal threaded tube 411, and the support screw 412 passes through the positioning through hole 413 to fix the rotating slide 407. After the intelligent transformer is installed, the power supply to the transformer is turned on, and the intelligent transformer starts to work. The blower 403 is started, and air enters the blower 403 from above and flows from the fixed air ducts 405 on both sides. Then, the air is sprayed out along the cooling air holes 409 of the rotating slide 407 to cool the transformer after it is started. The air delivered by the dry-type transformer fan 324 can enter the connecting hole 321 and the ventilation duct 320 through the air supply hole 322 in sequence, and finally exit from the hot air hole 323 to accelerate the cooling. If the ambient temperature is not high, the cooling can be completed by the dry-type transformer fan 324 alone. In this case, the rotating slide 407 is stored in the fixed air duct 405 to reduce the space it occupies and facilitate the maintenance and repair operations of the operators. If the transformer temperature continues to rise and exceeds the normal operating temperature in a short period of time, the temperature sensor 418 detects the abnormally high temperature. Then, through the monitoring control box 332, the electric control valve 416 is activated, the control tube 415 is opened, and the carbon dioxide cylinder 417 and the fixed air duct 405 are connected. The compressed carbon dioxide inside the carbon dioxide cylinder 417 will be sprayed out to the outside of the transformer through the cooling air hole 409. When the liquid carbon dioxide is sprayed out from the carbon dioxide cylinder 417, it expands in volume and absorbs heat. The dry and cold carbon dioxide is blown towards the transformer and cools it down quickly, preventing the transformer from catching fire and ensuring its safety. If the above-mentioned cooling fails, the transformer continues to heat up, and the temperature exceeds the safe range, causing a small fire. At this time, the transformer temperature is too high, and some heat is transferred to the heat conduction frame 309 through the top support plate 302. Another part of the heat is transferred to the heat conduction frame 309 through the ventilation channel 320 and hot air hole 323 of the iron core 2, causing the temperature of the heat conduction frame 309 to be too high. The hot melt frame 310 softens and cannot support the counterweight junction box 311. The hot melt frame 310 and the wiring pipe 312 are made of the same material, polypropylene, with a softening temperature of 150 degrees Celsius. The conductive sheet of the wiring pipe 312 is located at the bottom of the wiring pipe 312. At this high temperature, both the hot melt frame 310 and the wiring pipe 312 will soften, the wiring pipe 312 will separate from the wiring plug 313, and both the first electromagnet 308 and the second electromagnet 318 will be de-energized. The de-energization of the first electromagnet 308 causes the force-bearing iron plate 307 to separate from the first electromagnet 308. The fire-resistant folding curtain 305 unfolds under the pull of the counterweight ring 306. The fire-resistant folding curtain 305 is made of asbestos cloth, and the bent thin spring plate 328 also pushes the fire-resistant folding curtain 305 to unfold faster, wrapping the transformer inside the fire-resistant folding curtain 305. When the thin spring plate 328 unfolds, it pushes the bottom clamp plate 326 and the top clamp plate 327 away from each other. The docking clamp plate 331 is pushed by the bottom clamp plate 326 and the top clamp plate 327 to pull the fire extinguishing bag 329 along the tear slit 330. When the thin spring plate 328 returns to a vertical flat plate, its restoring force will push the fire extinguishing dry powder in the fire extinguishing bag 329 to spread rapidly and spray it to the outside of the transformer. The fire extinguishing dry powder covers the outside of the transformer, quickly extinguishing the fire. And through the isolation of the fire-resistant folding curtain 305, the air entering is reduced, accelerating the fire extinguishing. When the second electromagnet 318 is de-energized, it will no longer attract the horizontal plate 314. Under the pushing action of the lifting spring 319, the annular storage box 303 will rise along the limit stop 325, and the fixed terminal 301 and the movable terminal 316 will separate, disconnecting the wiring and preventing the power supply from continuing to be connected and causing more serious problems. The de-energization of the first electromagnet 308 and the second electromagnet 318 can also be manually and remotely controlled by the monitoring and control box 332. If the monitoring and control box 332 fails due to high temperature and circuit failure, it can also be completed by the hot melt frame 310 and the wiring tube 312. This double protection makes it safer and more reliable. Moreover, the component is small in size and easy to realize the fire extinguishing power cut-off operation, making it more convenient to use. The auxiliary cooling component 4 can cool down the transformer during use and quickly cool it down in case of abnormal overheating, while the fire extinguishing and cooling component 3 can quickly isolate and extinguish the fire when the temperature is too high and causes a fire. With multiple protections, it can ensure safety and reliability at all stages of transformer use.
