Description

Technical Field

[0001] This invention relates to the field of substation technology, specifically to an outdoor intelligent prefabricated box-type substation. Background Technology

[0002] Prefabricated substations, also known as box-type substations, are compact, outdoor, integrated power distribution units prefabricated in a factory. They are divided into three independent functional compartments: a high-voltage compartment, a transformer compartment, and a low-voltage compartment. Internally, they integrate high-voltage switches, distribution transformers, low-voltage distribution cabinets, metering, reactive power compensation, and various protection components. Automated monitoring, communication, and temperature measurement and cooling auxiliary systems can be added as needed. All assembly, wiring, commissioning, and factory testing are completed in the manufacturing plant. The entire unit is encapsulated in a protective metal enclosure. After transportation to the construction site, it only requires hoisting into place and connecting the incoming and outgoing cables to be put into operation. Compared to traditional substations… The integrated civil engineering substation boasts outstanding advantages such as high integration, compact size, small footprint, short construction period, flexible site selection, convenient operation and maintenance, lower overall investment, and strong environmental adaptability. It can realize multiple power supply modes such as ring network, terminal, and dual power supply. It is mainly used in urban residential communities, commercial plazas, industrial parks, municipal roads, wind and photovoltaic power stations, mining sites, and various temporary projects. It undertakes the core power distribution functions of high-voltage power reception, transformation, and low-voltage power distribution and transmission. The enclosure is equipped with a complete insulation, ventilation, lightning protection, and anti-misoperation interlocking protection structure, ensuring safe and reliable operation and adapting to long-term outdoor all-weather operation scenarios. In the existing technical field, there are many technical shortcomings in the wiring and circuit switching control of outdoor prefabricated substations. Traditional wiring methods mostly rely on manual connection and tightening operations, which makes it difficult to unify the connection accuracy and clamping consistency. Under long-term outdoor conditions, problems such as loose wiring, contact misalignment, and uneven fit gaps are prone to occur, which can easily lead to increased contact resistance, local heating, arc discharge, and even short circuit faults. At the same time, the wiring parts of traditional equipment lack an integrated automatic insulation protection structure. The exposed wiring parts are susceptible to corrosion from outdoor moisture, dust, condensation, and temperature changes, resulting in poor insulation protection reliability and insufficient weather resistance of the equipment. In addition, the switching of high-voltage circuits in traditional prefabricated substations mostly relies on pure electrical switches to achieve on / off control. Under abnormal conditions such as system overload, short circuit, and device failure, there are safety hazards such as electrical adhesion, malfunction, and inability to completely disconnect. There is a lack of independent, reliable, and electrically independent physical disconnection and protection mechanisms. Conventional electrical control switches cannot achieve rapid hard disconnection under fault conditions, resulting in insufficient equipment operation and maintenance safety and timely fault handling.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the electrical connection between the external high-voltage line and the high-voltage distribution cabinet of the central control power distribution system, the outgoing wires of the high-voltage distribution cabinet and the incoming wires of the transformer system are respectively threaded into the wire-threading cylinders of the automatic wiring components on the left and right sides. Then, the control cabinet of the central control power distribution system starts the micro electric telescopic rod, micro motor and electric telescopic rod through the preset program. The micro electric telescopic rod drives the first slider to slide axially along the limiting groove. Relying on the hexagonal kinematic pair formed by the first slot seat, the second slot seat and the connecting rod seat, and with the guiding and limiting effect of the sliding pin, the mechanism offset and torsional degrees of freedom are eliminated, and the slot seats and fixed ends are driven to synchronously retract radially to achieve precise clamping and fixing of the wires. After the wires are clamped, the micro motor drives the first cylindrical cam to rotate, and with the help of its differentiated lead spiral groove, pushes the connecting pin, which drives the sliding seat, connecting rod and base plate to move forward as a whole, so that the terminal and the wire are precisely connected. Finally, the electric telescopic rods on both sides push the connecting ring and the insulating cylinder forward to completely cover the connection position of the terminal and the wire, completing the automated wiring and insulation protection operation.

[0013] 2. By pressing the button, the second cylindrical cam is driven downward. Under the positioning constraint of the limit pin and the spring plate, a single press can achieve a 180-degree indexing rotation, driving the bottom pressure rod to complete the work position switch. When the pressure rod is in the pressing position, the push ball head rod drives the rotating seat to deflect, driving the limit rod to push the grooved cylinder to squeeze the third spring, so that the sliding joint slides along the constraint groove and fits tightly with the terminal, connecting the conductive path between the high-voltage distribution cabinet and the transformer system, ensuring the normal power distribution operation of the equipment. At the same time, the central control power distribution system monitors the transformer operating voltage and current data in real time. When abnormal operating data is detected, pressing the button again will rotate the second cylindrical cam another 180 degrees, causing the pressure rod to switch to the yielding position, releasing the push constraint on the ball head rod. Under the rebound action of the third spring, the grooved cylinder drives the sliding joint to reset, separating from the terminal and disconnecting the conductive path, realizing a rapid physical disconnection of the circuit.

[0014] In summary, this invention enables automated, synchronized, and high-precision clamping and docking of high-voltage wiring links, avoiding assembly deviations and poor contact problems caused by manual wiring, reducing contact resistance and heat loss at wiring points, and achieving integrated automatic insulation protection at wiring locations. This effectively isolates the conductive connection points from the corrosive effects of harsh outdoor environments, improving the overall insulation level, weather resistance, and long-term operational reliability of the equipment. Furthermore, it constructs an independent mechanical self-locking on / off control system, which can achieve stable circuit conduction and physical hard disconnection independently of the electrical control system, eliminating safety hazards such as electrical switch adhesion, malfunction, and inability to disconnect. It can also quickly cut off the power supply circuit when equipment malfunctions, significantly improving equipment fault protection capabilities and operational safety. Attached Figure Description

[0022] The working principle is as follows: Step 1: The staff hoisted the substation casing 1 to the designated outdoor installation location and secured it. They then electrically connected the external high-voltage line to the incoming terminal of the high-voltage distribution cabinet inside the central control power distribution system 5. The outgoing wires of the high-voltage distribution cabinet in the central control power distribution system 5 were inserted into the conduit 31 cavity of the left-side automatic wiring component 3, and the incoming wires of the transformer system 6 were inserted into the conduit 31 cavity of the right-side automatic wiring component 3. The wires on both sides were inserted from the conduit 31 cavity to the rear and passed through the guide groove 33. Simultaneously, the preset program inside the control cabinet of the central control power distribution system 5 sequentially controlled the micro electric telescopic rod 313, the micro motor 327, and the electric telescopic rod 321 to start. The axial feed displacement of the telescopic end of the micro electric telescopic rod 313 was initiated. This causes the first slider 36, which is coaxially fitted, to move, allowing it to slide linearly along the inner cavity of the corresponding upper limit groove 35. Since the inner cavities of the first slot seats 37, which are symmetrically distributed on the outer periphery of the mounting frame 32, and the inner cavities of the three second slot seats 310, which are symmetrically distributed on the outer periphery of the mounting frame 32, are respectively connected to one end of the connecting rod seats 312 on both sides, the second slot seats 310, under the limiting constraint of the second slider 39, form a hexagonal kinematic pair between the first slot seats 37, the second slot seats 310, and the connecting rod seats 312. The kinematic pair, guided by the sliding pin 311 inserted into the radial groove 34, restricts the lateral offset and torsional movement between the connecting rod seats 312 and the first slot seats 37 and the second slot seats 310. The rotational and non-radial offset degrees of freedom are retained, with only the relative sliding degree of freedom between the two along the hexagonal guide surface retained. When the uppermost first slider 36 feeds axially, it simultaneously pushes the three sets of connecting rod seats 312 to generate equal amplitude movements. The connecting rod seats 312 transmit the component thrust to the outer first slot seat 37 and second slot seat 310 through the hexagonal kinematic pair. The three sets of first slot seats 37 and second slot seats 310, under the constraint of the first slider 36 and second slider 39 at their corresponding positions, retract radially inward synchronously. Relying on the three fixed ends 38 set on the inner side of the three sets of first slot seats 37, they retract inward synchronously and contact the wire, thereby realizing the wire clamping operation. After the wire is fixed, the micro motor 327 drives the first cylindrical cam 326 to rotate around its own central axis. During the rotation of the first cylindrical cam 326, the connecting pin 325 is pushed against by the groove wall of the spiral groove limiting groove, which drives the sliding seat 323 to complete the axial reciprocating linear displacement along the limiting guide rail frame 322. The sliding seat 323 is quickly driven by the connecting rod 324 to drive the base plate 315. Under the constraint of the limiting guide rail assembly 314, the base plate 315 drives the entire structure above it to move forward, and the front terminal of the wiring end 317 is connected to the wire. After the connection is completed, the electric telescopic rods 321 on both sides extend synchronously to drive the connecting ring 320 to move forward, so that the connecting ring 320 drives the insulating cylinder 319 to move forward along the inner side of the cylindrical cover 318, so that the insulating cylinder 319 covers the wiring end 317 and the wiring position of the wire. Step 2: After the wire connection is completed, the operator applies axial pressure to the button 44 externally, causing the button 44 to drive the second cylindrical cam 45 to synchronously produce downward axial displacement. During the downward movement of the second cylindrical cam 45, in conjunction with the circumferential limiting guide groove, and the positioning constraints of the limiting pin 48 and the spring plate 49, a single press corresponds to a 180-degree circumferential indexing rotation. The pressure rod 46 below the second cylindrical cam 45 rotates synchronously with the shaft, and the pressure rod 46 completes the alternating 180-degree rotation position switching. The pressure rod 46 forms a 180-degree alternating rotation position under the two indexing positions. The device operates in two phases: periodic pushing and yielding. When the pressure rod 46 is in the pushing position, the bottom bearing surface of the pressure rod 46 continuously applies a directional mechanical thrust to the ball head rod 412 on one side. With the cooperation of the ball head rod 412, it drives the rotating seat 411 to rotate axially. The rotating seat 411 drives the limiting rod 413 to push against the grooved cylinder 416 against the groove wall, and compresses the third spring 419. This causes the sliding joint 417 to slide to the right along the inner wall of the constraint groove 414 and tightly press against the conductive contact point of the wiring terminal 415, forming a contact... A stable conductive path ensures circuit closure and conduction. In the central control power distribution system 5, the outgoing circuit of the high-voltage distribution cabinet connects to the terminal 317 in the left-side automatic wiring component 3 via the grooved cylinder 416 and terminal 415 in the physical disconnect component 4. The circuit then connects to the incoming circuit of the transformer system 6 via the terminal 317 in the right-side automatic wiring component 3, enabling normal operation. During operation, the central control power distribution system 5 continuously monitors the operating voltage and current data of the transformer system 6. If any abnormal data is detected, the system will immediately take action. The operator applies axial pressure to button 44 again, triggering the second cylindrical cam 45 to rotate 180 degrees to complete the station switch. Then, the pressure rod 46 rotates back to the retraction release station. The bottom bearing surface of the pressure rod 46 is released from the contact constraint with the ball head rod 412. The grooved cylinder 416, relying on the elastic restoring force of the third spring 419, drives the sliding joint 417 to slide in the opposite direction along the inner cavity of the constraint groove 414 and away from the terminal 415. The two sets of sliding joints 417 and terminal 415 separate from each other and cut off the conductive path, realizing a physical and rapid disconnection.
