Description

Technical Field

[0001] This invention relates to the field of dry-type transformer technology, specifically to a high-efficiency intelligent dry-type transformer. Background Technology

[0002] Dry-type transformers are core substation equipment that do not rely on insulating oil for internal insulation and heat dissipation. Unlike oil-immersed transformers, they rely entirely on air as the insulation and cooling medium. They can be equipped with fans to achieve forced air cooling and enhance heat dissipation. They have outstanding fire-retardant performance and no safety hazards such as oil leakage or explosion. They are suitable for indoor safe power supply environments. The equipment can be installed flexibly. It can be installed independently in the power distribution space, or multiple units can be arranged side by side in indoor power distribution rooms, basement power distribution rooms, rooftop special equipment floors, or other ground or hardened floor platforms according to the large power load requirements of buildings and factories. They are widely used in power distribution places with high requirements for fire prevention, environmental protection, and safety, such as high-rise commercial complexes, residential communities, hospitals, schools, and precision processing plants. In the current technical field, traditional dry-type transformer power distribution systems suffer from problems such as delayed fault response, large human error, and untimely power-off isolation when transformers experience overload or abnormal voltage. This can easily lead to safety hazards such as continuous operation with faults, line overheating, arcing, and even short-circuit damage. Furthermore, traditional power distribution structures often use a single fixed circuit layout, lacking automatic fault bypass switching capabilities. A single transformer failure requires a complete shutdown and power outage for maintenance, failing to guarantee uninterrupted power supply and exhibiting poor fault tolerance and operational stability. In addition, traditional electrical connection structures often employ fixed hard connections or simple manual plug-and-play structures, resulting in low connection accuracy, large contact gaps, and a tendency for loose connections, overheating, and loosening over long-term operation. These issues make them unsuitable for the high-precision, high-reliability, and uninterrupted industrial power distribution requirements of today. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. The first rotating rod is driven by the first motor to rotate on a fixed axis. Through the hinged relationship, the rack rod is pushed and pulled to make a stable linear reciprocating motion under the horizontal limit guide of the limit slot seat. Then, the meshing drive gear and the rotating shaft rotate counterclockwise, causing the second rotating rod to swing counterclockwise. The radial groove of the second rotating rod and the groove of the slide plate form a double trajectory constraint. With the cooperation of the limit pin, the single swing motion is decoupled into a horizontal and vertical composite displacement. The telescopic frame is driven to move in an orderly manner under the guide limit of the limit slider and the slot seat. First, the docking plug is lifted upward to disengage from the first plug-in connector, realizing the physical power disconnection and isolation of the high voltage side of the fault transformer. Then, it moves horizontally to the right to align with the second plug-in connector. Finally, it is pressed down vertically to complete the plug-in docking. In this way, the high voltage input circuit of the main body of the fault dry-type transformer is cut off, and the power supply line is transferred to the third terminal of the outgoing mechanism through the second plug-in connector and the second terminal, quickly building a fault bypass backup conductive path.

[0013] 2. The left-side adjustment unit disengages the left-side plug-in terminal block from the third plug-in connector, cutting off the original low-voltage output circuit of the faulty transformer. Simultaneously, the left-side miniature telescopic rod retracts and rotates, causing the pusher to disengage from the limiting position on the rotating plate. The limiting spring releases its energy and rebounds, pulling the rotating plate to rotate and tilt, causing the terminal block to fold and retract, preventing line interference. At the same time, the right-side miniature telescopic rod extends and lowers, pushing the pusher to press against the rotating plate, overcoming the spring preload torque, and returning the rotating plate to a horizontal working position, ensuring the plug-in terminal block is vertically aligned. Subsequently, the right-side adjustment unit precisely inserts the right-side plug-in terminal block into the fourth plug-in connector, completing the electrical connection. Finally, the third terminal block, through the right-side connection structure, forms a complete bypass closed loop with the outgoing line, stably returning electrical energy to the distribution cabinet. This achieves electrical isolation of the faulty transformer and fully automatic switching of the distribution circuit, ensuring the continuous, stable, and uninterrupted operation of the overall power distribution system.

[0014] In summary, this invention, through its integrated design of adaptive electrical connection and dual-circuit redundant switching, effectively addresses the industry pain points of traditional dry-type transformer power distribution systems, such as strong reliance on manual operation, delayed fault response, incomplete fault isolation, inability to provide uninterrupted power supply, poor electrical connection stability, low transmission switching accuracy, and susceptibility to poor line contact and equipment damage. It enables real-time fault perception, autonomous response, and unmanned emergency switching, significantly shortening fault handling response time and eliminating safety hazards and operational errors caused by manual operation. Through a collaborative mechanism of physical disconnection and automatic bypass circuit conduction, it achieves complete electrical isolation of faulty equipment and seamless switching of power supply circuits, effectively ensuring uninterrupted operation of the power distribution system and significantly improving its fault tolerance and operational reliability. Simultaneously, it achieves high-precision automatic alignment, smooth insertion and removal, and tight contact at electrical connection points, effectively eliminating line connection gaps and avoiding adverse conditions such as loose connections, overheating, and arc discharge, thus improving the stability and safety of electrical connections. This, in turn, enhances the intelligence, precision, safety, and long-term stable operation performance of dry-type transformer power distribution systems. Attached Figure Description

The second motor 511 can receive control commands from the second sub-control module 42 to realize start-stop, forward and reverse rotation, and precise angle control.

[0025] The working principle is as follows: Step 1: Under normal energized operation, the line adjustment component 3 inside the incoming line mechanism 2 is in the working position, and its bottom connector 318 is inserted into the first plug-in connector 25 on the left side to achieve stable connection of the electrical path on the incoming side. At the same time, the plug-in terminal 56 of the execution unit inside the outgoing line mechanism 4 completes the pre-connection operation and is inserted into the third plug-in connector 45 to construct the conventional output circuit on the low-voltage side of the transformer. The power supply circuit of the entire equipment takes the distribution cabinet 6 as the power distribution core. The high-voltage power output from the distribution cabinet 6 is stably transmitted through the neatly laid incoming line 9. After the line is transferred through the first connector 23, it is sequentially transmitted to the internal transformer body 1 through the integrated relay conductive structure composed of the built-in connector 317, the connector 318, and the first plug-in connector 25. In the voltage conversion assembly, the input high-voltage AC power is stabilized and stepped down to low-voltage AC power that meets the operating conditions through the electromagnetic transformation principle of the iron core and windings inside the dry-type transformer body 1, thus completing the voltage conversion operation. The low-voltage power after transformation is led out through the fourth terminal 44 connected to the output end of the dry-type transformer body 1, and then transmitted through the low-voltage side relay conductive circuit formed by the left plug-in terminal 56 and the third plug-in connector 45. Finally, it flows back to the distribution cabinet 6 through the laid out line 11, forming a complete closed-loop power supply circuit. During the operation of the equipment, the intelligent monitoring module built into the distribution cabinet 6 can continuously collect, count and monitor the real-time voltage, working current, load power and other core operating parameters of the two dry-type transformer bodies 1 under the operating conditions, so as to realize the real-time control and abnormal early warning of the equipment operating status. Step 2: During real-time monitoring in distribution cabinet 6, once an operational fault such as abnormal voltage or current overload is detected in the dry-type transformer body 1, the monitoring system generates a fault alarm signal and transmits it to control cabinet 7. Control cabinet 7 calls the internally preset fault emergency control program, triggering the first sub-control module 22 inside the rear inlet mechanism 2 of the dry-type transformer body 1 at the fault location to start working. The first sub-control module 22 executes the control logic, driving the first motor 34 of the line adjustment component 3 to be energized and run. The first motor 34 outputs torque, driving the first rotating rod 33 to perform a fixed-axis rotational motion. The end of the first rotating rod 33 forms a hinged transmission engagement with the rack rod 38. During the rotation, the first motor 34 outputs torque, driving the first rotating rod 33 to perform a fixed-axis rotational motion. The rack 38 is subjected to a push-pull driving force, causing it to produce a stable reciprocating linear displacement. Since the rack 38 is inserted into the limiting slot seat 37, and relying on the lateral limiting guide structure of the limiting slot seat 37, the rack 38 can complete feed and retraction linear motion along the horizontal reference direction. Under the meshing driving action of the rack 38, the gear 36 meshing with it rotates synchronously counterclockwise, thereby driving the coaxially fixed rotating shaft 35 to rotate synchronously counterclockwise. The second rotating rod 310, fixed to the rear end of the rotating shaft 35, rotates synchronously, forming a counterclockwise swing motion with a maximum swing angle of nearly 270°. During the swinging process of the second rotating rod 310, its internal structure is perforated. The radial groove 311 and the limiting pin 316 fixed to the front of the telescopic frame 315 form a dynamic sliding fit pair. The limiting pin 316 slides along the contour of the n-shaped groove opened in the inner cavity of the slide plate 39 under force. Through the angular constraint of the radial groove 311 and the irregular trajectory constraint of the slide plate 39, a double trajectory coupling limiting structure is formed, which decouples the circumferential swing motion of the second rotating rod 310 into a composite displacement power of horizontal and vertical bidirectional coordination, and transmits it to the telescopic frame 315 at the bottom. The slot seat 314 cooperates with the limiting slider 313 to limit the sliding movement inside the limiting slide seat 312, driving the telescopic frame 315 to follow the preset trajectory. First, it drives the bottom docking plug 318 to lift vertically upward, disengaging from the... The plug-in state of the first plug-in connector 25 on the left side realizes the physical power disconnection and isolation of the high-voltage incoming line side of the fault transformer. Then, it drives the docking plug 318 to move horizontally to the right to complete the vertical alignment and calibration with the second plug-in connector 26 on the right side. Finally, it drives the docking plug 318 to move vertically downward and plug into the second plug-in connector 26 to complete the bypass switching of the incoming line circuit. Through the above actions, the high-voltage power supply input circuit of the fault dry-type transformer body 1 is disconnected. At the same time, the incoming line power is transferred to the third terminal 43 of the front outgoing line mechanism 4 through the second plug-in connector 26 and the second terminal 24 to complete the line transfer, thus constructing a bypass backup conductive path in the fault state. Step 3: After the incoming circuit switching operation is completed, the control cabinet 7 synchronously controls the second sub-control module 42 inside the front outgoing mechanism 4 of the dry-type transformer body 1 corresponding to the fault to start response. The second sub-control module 42 controls the second motor 511 of the corresponding adjustment unit and the miniature telescopic rod 53 of the execution unit to work together. The second motor 511 of the left adjustment unit starts to run, driving the screw screw of the screw assembly 510 to rotate on the fixed axis. Through the screw nut screw transmission principle, the rotational motion is converted into linear lifting driving force, which drives the left wheeled lifting frame 59 to slide vertically upward along the vertical slide rail 58, and synchronously drives the left execution unit to lift as a whole, so that the left plug-in terminal 56 is disengaged. In conjunction with the plug-in connection of the third plug-in connector 45, the original low-voltage output circuit of the faulty dry-type transformer body 1 is cut off, achieving electrical isolation on the low-voltage side. At the same time, the miniature telescopic rod 53 of the left-side actuator initiates a reverse retraction action. The entire telescopic rod completes a reverse rotation swing around the axis of the top rotating shaft seat, synchronously pulling the rotating plate 55, which is hinged at the telescopic end, to rotate and reset around its own axis. The push frame 54, which is fixedly connected to the miniature telescopic rod 53, deflects synchronously with the telescopic rod, causing the bottom end of the push frame 54 to disengage from the pressing and limiting state against the rotating plate 55. The limiting spring 57, which was originally compressed and stored energy, is released from the load constraint and rebounds by relying on its own pre-tightened elastic potential energy, pulling the rotating plate 55 in the opposite direction around the bottom axis of the rotating frame 52. The rotation causes the rotating plate 55 to switch from its initial horizontal docking state to an inclined storage state, simultaneously driving the insert terminal 56 to retract upwards. Finally, in conjunction with the rotating frame 52, the entire assembly completes an inward folding and storage, avoiding wiring interference. Simultaneously, the miniature telescopic rod 53 in the right-side actuator extends outwards and swings downwards around the axis of the rotating shaft, driving the hinged rotating plate 55 to deflect downwards synchronously. The pusher 54, fixed to the telescopic rod, moves synchronously, its end continuously pressing against the side of the rotating plate 55 and applying a pushing force. This overcomes the pre-tightening reset torque of the limit spring 57, pushing the rotating plate 55 from the inclined storage state back to its horizontal working state, ensuring the right-side insert terminal 56 remains vertically downward. Upon receiving the attitude, the second motor 511 on the right side starts, driving the corresponding lead screw assembly 510 to rotate. This drives the right wheeled lifting frame 59 to move precisely upward along the vertical slide rail 58, allowing the right plug-in terminal 56 to be inserted into the fourth plug-in connector 46, completing the electrical connection. At this point, the bypass circuit is fully connected. The electrical energy connected to the third terminal 43 can be transferred through the bypass conductive structure formed by the plug-in terminal 56 of the right execution unit and the fourth plug-in connector 46, combined with the outgoing line 11 to form a closed loop, stably returning the electrical energy to the distribution cabinet 6. This completes the entire emergency operation of fault transformer isolation and automatic bypass circuit switching, ensuring the uninterrupted and stable operation of the power distribution system.
