Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to a 10kV primary and secondary integrated pole-mounted circuit breaker FTU anti-misoperation protection device and its installation method. Background Technology

[0002] FTU (Feeder Terminal Unit) is a key piece of equipment in distribution network automation systems. It is typically installed on outdoor utility poles and is responsible for monitoring and controlling feeder lines. Traditional enclosed FTUs have their control switches and data interfaces directly exposed to the outside, making them highly susceptible to power outages or erroneous commands due to accidental contact, malicious operation, or contact by small animals. This poses a serious threat to the safety and reliability of power grid operation.

[0003] Currently, FTUs are typically protected by simple metal enclosures. However, these enclosures often have several drawbacks: installation requires a power outage, affecting power supply continuity; the enclosures are bulky, cumbersome to open, and extremely inconvenient to maintain; they lack effective access control and cannot record operator information; and their passive protection makes them susceptible to deformation under impact, failing to provide truly intelligent and efficient protection. Therefore, there is an urgent need for a protective device that can be quickly installed, easily maintained, and equipped with intelligent management functions without affecting the normal operation of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a 10kV primary and secondary integrated pole-mounted circuit breaker FTU anti-misoperation protection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an FTU anti-misoperation protection device, comprising: An outer cover is used to enclose the FTU equipment. A base is attached to the bottom of the outer casing, and the base has a cable pass-through port for the FTU data cable to pass through; The movable door panel is movably connected to the base via a hinge mechanism and is used to open or close the bottom opening of the base; An electronic lock is disposed between the movable door panel and the base, for locking the movable door panel and the base in the closed state; The system includes a protective mechanism that is slidably mounted on the base, having a protective position that covers the electronic lock and an operating position that exposes the electronic lock; the protective mechanism is fixed in the protective position by a magnetic component.

[0006] Preferably, the protective mechanism includes a slider slidably connected to the base, a protective cover connected to the slider, and a pusher block disposed on the protective cover; the magnetic suction assembly includes a magnetic block disposed within the slider.

[0007] Preferably, the magnetic attraction component includes magnetic blocks respectively disposed on the two sliders, and when the protective mechanism is in the protective position, the two magnetic blocks attract each other to achieve a limiting position.

[0008] Preferably, the magnetic poles of the two magnetic blocks that are close to each other are opposite.

[0009] Preferably, the base is provided with a sliding groove, and the slider slides in cooperation with the sliding groove.

[0010] Preferably, the electronic lock is a passive NFC electronic padlock.

[0011] Preferably, the passive NFC electronic padlock supports access authentication and operation log management via a smart terminal.

[0012] Preferably, the outer cover and the base, and the base and the movable door panel are detachably fixedly connected by bolts.

[0013] Preferably, the outer cover is made of stainless steel.

[0014] This invention also discloses an installation method for the FTU anti-misoperation protection device as described above, comprising the following steps: The outer cover is fixedly installed on the outside of the FTU device; The FTU data cable is introduced into the outer casing through the cable guide port on the base; Close the movable door panel and use the electronic lock to secure it to the base; Move the protective mechanism to the protective position and fix it in place by the magnetic suction component to cover the electronic lock.

[0015] Compared with the prior art, the present invention provides a 10kV primary and secondary integrated pole-mounted circuit breaker FTU anti-misoperation protection device, which has the following beneficial effects: The 10kV primary and secondary integrated pole-mounted circuit breaker FTU anti-misoperation protection device, through the structural design of setting a dedicated line port on the outer casing and bottom protective platform, makes it possible to install the entire protection device without powering down the FTU equipment or plugging and unplugging its data cable during subsequent opening and closing maintenance. This completely avoids power outages caused by protection operations and is particularly suitable for distribution network systems that require high power supply reliability.

[0016] The 10kV primary and secondary integrated pole-mounted circuit breaker FTU anti-misoperation protection device has an outer casing made of 304 stainless steel, which is robust in structure. After being tested, it showed almost no deformation after withstanding an external force of 25kg. It can effectively resist external damage and the influence of harsh environment, providing a robust physical barrier for the internal FTU equipment and significantly reducing the risk of failure caused by external factors.

[0017] This 10kV primary and secondary integrated pole-mounted circuit breaker FTU anti-misoperation protection device integrates a passive NFC electronic padlock. Authorized personnel can only unlock the device quickly (unlocking time <5s) using a mobile phone with NFC functionality, making operation convenient. Simultaneously, the backend APP allows for precise management of unlocking permissions and recording of operation logs, achieving knowability, controllability, and traceability of the operation process, technically eliminating unauthorized personnel's misoperation or malicious operation.

[0018] This 10kV primary and secondary integrated pole-mounted circuit breaker FTU anti-misoperation protection device features a modular component design and a reasonable installation procedure, making on-site installation and subsequent opening and closing maintenance simple and quick. Tests show that a single opening and closing operation can be completed in less than 20 seconds, greatly reducing the workload of maintenance personnel and improving maintenance efficiency.

[0019] This 10kV primary and secondary integrated pole-mounted circuit breaker FTU anti-misoperation protection device moves the protective cover by pushing the push block, which can disengage the magnetic block and move the protective cover out, making it easy to operate the passive NFC electronic padlock. The operation is simple. When the protective cover is closed, it is limited by magnetic block adsorption, which can effectively reduce the impact of the external environment on the passive NFC electronic padlock and extend its service life.

[0020] The 10kV primary and secondary integrated pole-mounted circuit breaker FTU anti-misoperation protection device has a raised structure at the bottom of the push block, which makes it easier for users to push and improves the convenience of operation. The outer cover, bottom protective platform and base plate are stably installed through the connection of bolts and nuts, and the structure is reliable. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] This invention provides the following technical solutions: Combination Figures 1 to 8 The 10kV primary and secondary integrated pole-mounted circuit breaker FTU anti-misoperation protection device includes an outer cover 1, a bottom protective platform 3 is provided at the bottom of the outer cover 1, a first nut 10 is provided at the top of the bottom protective platform 3, a first bolt 9 is connected to the inner ring thread of the first nut 10, and a protective mechanism 2 is provided at the bottom of the bottom protective platform 3. The bottom of the bottom protective platform 3 is fixedly connected to the first lock 4, the top of the bottom protective platform 3 is provided with the second nut 12, the inner ring of the second nut 12 is threaded with the second bolt 11, and the bottom of the bottom protective platform 3 is provided with the second base plate 7. The bottom of the second base plate 7 is fixedly connected to a hinge 8, the top of the hinge 8 is fixedly connected to the first base plate 6, the bottom of the first base plate 6 is fixedly connected to a second latch 5, and the first latch 4 is internally connected to a passive NFC electronic padlock 13. The protective mechanism 2 includes a support plate 21, which is fixedly connected to the bottom of the bottom protective platform 3. A slide groove 22 is fixedly connected to the inner side of the support plate 21. A slider 23 is slidably connected to the inner wall of the slide groove 22. A magnetic block 24 is fixedly connected inside the slider 23. A short shaft 25 is fixedly connected to the outer side of the slider 23. A protective cover 26 is fixedly connected to the end of the short shaft 25 away from the slider 23. A push block 27 is fixedly connected to the bottom of the protective cover 26.

[0026] Furthermore, the bottom of the push block 27 has a rectangular opening, and the rectangular openings are evenly distributed at the bottom of the push block 27, so that the bottom of the push block 27 is raised, making it convenient for the operator to push the push block 27 to move.

[0027] Furthermore, there are two magnetic blocks 24, with opposite magnetic poles on the sides of the two magnetic blocks 24 that are close to each other, which facilitates the attraction of the two magnetic blocks 24 and thus achieves the purpose of closing the protective cover 26.

[0028] Furthermore, a slot is provided on the left side of the slide groove 22, through which the short shaft 25 passes and moves, allowing the short shaft 25 to move through the slot.

[0029] Furthermore, both the bottom of the bottom protective platform 3 and the outer cover 1 are provided with a through hole 1, through which the first bolt 9 passes, so that the bottom protective platform 3 and the outer cover 1 can be connected and fixed by the cooperation of the first bolt 9 and the first nut 10 with the through hole 1.

[0030] Furthermore, through holes 2 are provided inside the second base plate 7 and at the bottom of the bottom side protective platform 3. The second bolt 11 passes through the through holes 2, which facilitates the connection and installation of the second base plate 7 and the bottom side protective platform 3 by cooperating with the second bolt 11 and the second nut 12 through the through holes 2.

[0031] Furthermore, the first base plate 6 is movably connected to the second base plate 7 via a hinge 8, and the bottom protective platform 3 is provided with a cable passage for accommodating FTU data cables.

[0032] Furthermore, the outer cover 1 is made of 304 stainless steel, and the passive NFC electronic padlock 13 supports permission management and unlocking operations via a smartphone APP, with an average unlocking time of less than five seconds.

[0033] An installation method for a 10kV primary and secondary integrated pole-mounted circuit breaker FTU anti-misoperation protection device includes the following steps: Secure the top of the outer casing 1 to the top of the FTU device; Pass the FTU data cable through the cable guide port 3 on the bottom protective panel; Close the first base plate 6 via the hinge 8 and lock it to the bottom protective platform 3 using the passive NFC electronic padlock 13; Pushing the pusher 27 causes the protective cover 26 to slide along the short shaft 25, causing the slider 23 to slide. The two magnetic blocks 24 are attracted, and the protective cover 26 closes and limits the movement, thus protecting the passive NFC electronic padlock 13.

[0034] In actual operation, when this device is used, firstly, the outer cover 1 is put on and fixed above the running FTU equipment. The design leaves sufficient gaps to ensure that it does not interfere with the FTU body. Then, the various data cables of the FTU are carefully introduced into the outer cover 1 through the cable passage reserved on the bottom protective platform 3, and connected to the corresponding interfaces below the FTU. The whole process does not require plugging or unplugging any cables, ensuring a continuous power supply.

[0035] The first base plate 6 is closed by rotating it with the hinge 8 so that it fits tightly against the bottom protective platform 3. At this time, the second latch 5 will also be inserted into the outside of the first latch 4. Then, the passive NFC electronic padlock 13 is used to lock the first latch 4, so that the protective cover forms a whole that completely seals the FTU operating surface.

[0036] Simultaneously pushing the two push blocks 27 away, the push blocks 27 can drive the protective cover 26 to move. The protective cover 26 can drive the slider 23 to slide and limit the movement on the inner wall of the slide groove 22 through the short shaft 25. The two magnetic blocks 24 will detach from the adsorption. At this time, the two protective covers 26 will move out from the outside of the passive NFC electronic padlock 13, which facilitates further operation and unlocking of the passive NFC electronic padlock 13. Similarly, pushing the two push blocks 27 closer together will cause the magnetic blocks 24 to meet and adsorb, limiting and closing the two protective covers 26. This can protect the passive NFC electronic padlock 13, reduce the impact of external factors on the passive NFC electronic padlock 13, extend the service life of the passive NFC electronic padlock 13, and facilitate the stable operation of the passive NFC electronic padlock 13.

[0037] When authorized maintenance personnel need to perform operations, they simply need to bring their NFC-enabled smartphone close to the passive NFC electronic padlock. The chip inside the padlock activates instantly by receiving energy from the NFC radio frequency field of the phone, verifying the encryption key permissions preset in the mobile app. Once the permissions are verified, the electromagnetic mechanism inside the lock activates, completing the unlocking process in an average of three seconds, which is much faster than traditional mechanical locks and greatly improves maintenance efficiency.

[0038] All unlocking operations can be authorized and logged through the back-end APP, enabling traceability of operators, time, and location, and meeting the stringent requirements for power system safety management.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
