Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0021] This utility model provides a novel outdoor switchgear embodiment one, see [link to embodiment]. Figure 1 This utility model provides a novel outdoor switchgear, including an outer casing, an incoming line unit and an outgoing line unit 10 disposed inside the outer casing, and a plurality of electronic components disposed within the outgoing line unit 10. The plurality of electronic components include: a circuit breaker, a gas box, a copper busbar, and a current transformer. Since the types and layout of the electronic components in the outgoing line unit 10 are no different from those in conventional outdoor switchgear, they will not be described further here.

[0022] In this invention, the inlet unit consists of an upper panel 6 and a lower panel 3, with a lower crossbeam 1 at the bottom and a hollow internal structure. A protective baffle 8 is provided at the top. Inside the hollow structure, an inlet cable 14, a first cable clamp 2, a second cable clamp 4, a cable connector sleeve 9, and a cable connector 7 are installed. An inlet cable hole is provided at the bottom of the hollow structure, through which the inlet cable 14 is inserted into the inlet unit from the outside. The first cable clamp 2 is located on the side of the inlet cable hole to fix the inlet of the inlet cable 14. The second cable clamp 4 is located in the middle of the hollow structure to allow the inlet cable 14 to enter vertically. The cable connector 7 is located at the connection between the inlet unit and the outlet unit 10 to allow the inlet cable 14 to connect to the interface of the outlet unit 10. The cable connector sleeve 9 is fitted over the outside of the cable connector. The cable connector sleeve 9 is preferably a post-type sleeve; the cable connector 7 is a silicone rubber prefabricated insulated shielded cable connector with a semi-conductive shielding layer on the surface. Using the above-mentioned materials, it can be touched even when energized.

[0023] Conventional outdoor switchgear incoming line units require air boxes, corresponding protective housings, and conductive copper busbars, etc. However, this solution directly uses two panels, one on top and one on the bottom, to replace an entire incoming line cabinet. This saves production costs and avoids resource waste while still achieving power configuration.

[0024] This embodiment illustrates the application scenario of the novel outdoor switchgear with specific examples. For example: (i) In the power supply of a small community, based on the community's power consumption scale and distribution, the outdoor switchgear of this utility model is set in a suitable location. The incoming cable 14 is connected to the 10kV power input line from the upstream substation. Through the power distribution controller, according to the power demand of the community (such as residential buildings, commercial areas, public facilities, etc.), the power is transmitted to the outgoing unit through the incoming cable 14 and reasonably distributed to the outgoing ports. For example, a portion of the power is distributed to the outgoing ports of residential buildings, and its voltage level is adjusted to 380V / 220V for residential power supply. Another portion of the power is distributed to the outgoing ports of commercial areas, and the corresponding voltage level and power quota are set according to the characteristics of commercial power consumption. In terms of equipment installation, according to the modular design, the transformer module, switch cabinet module, etc. are sequentially connected in the designated positions of the novel outdoor switchgear using connecting devices. At the same time, the heat dissipation and auxiliary heat dissipation devices are turned on to ensure that the temperature of the equipment during operation is within the normal range.

[0025] (II) In the power consumption scenario of an industrial park, the new type of outdoor switchgear is installed at the power supply center. The incoming cable 14 is connected to a higher voltage level (e.g., 35kV) power input line. Based on the power consumption needs of different factories and workshops within the park, power is flexibly allocated to the outgoing ports of each outgoing unit through a power distribution controller. Furthermore, the outgoing voltage level and power quota can be adjusted according to the factory's production characteristics. Regarding equipment installation, the layout is consistent with the aforementioned application scenario in small communities and will not be described further.

[0026] As can be seen from the above different real-time scenarios, the novel outdoor switchgear solution of this utility model can save resources by replacing an entire incoming line cabinet with two upper and lower panels. It can be flexibly applied according to different power consumption scenarios, effectively realize the power distribution of one input and multiple outputs, optimize the structural layout, meet various power consumption needs, and ensure the safe and stable operation of the power system.

[0027] This utility model also provides a second embodiment of a novel outdoor switchgear, see [link to embodiment]. Figure 2 The second embodiment is an improvement upon the first embodiment described above. The improvement lies in that the novel outdoor switchgear further includes a first protective device 11. The first protective device 11 is a protective mesh door and a corresponding mesh door frame installed at the end of the incoming line unit of the novel outdoor switchgear, used for initial installation of the incoming cable, operational observation, and protection, thus broadening the practicality and scalability of the novel outdoor switchgear.

[0028] This utility model also provides a third embodiment of a novel outdoor switchgear, see [link to embodiment]. Figure 3 The third embodiment is an improvement on the second embodiment described above. The improvement is that the new type of outdoor switchgear further includes a second protective device 13. The second protective device 13 is a protective baffle set on both sides of the operating surface inside the new type of outdoor switchgear to prevent accidental entry into the energized compartment, thereby improving the safety of the new type of outdoor switchgear.

[0029] This utility model also provides a fourth embodiment of a novel outdoor switchgear, see [link to embodiment]. Figure 2 The fourth embodiment is an improvement upon the third embodiment described above. The improvement lies in that the novel outdoor switchgear further includes an electromagnetic lock 12, which is located on the outside of the protective mesh door. By adding the electromagnetic lock 12, it ensures that only authorized personnel can enter the novel outdoor switchgear, effectively isolating and protecting the internal equipment and preventing unauthorized personnel from entering and causing misoperation.

[0030] This utility model also provides a fifth embodiment of a novel outdoor switchgear, see [link to embodiment]. Figure 1The fifth embodiment is an improvement upon the fourth embodiment described above. The improvement lies in that the new outdoor switchgear further includes a visual monitoring mechanism 5. This mechanism 5 is located on the outer side of the incoming line unit and the outgoing line unit 10, and its height is consistent with the height of the live display. Preferably, the visual monitoring mechanism 5 uses a tempered glass viewing window, allowing observation of the operating status of each line and equipment inside the new outdoor switchgear without opening the door. It also enables timely response measures to be taken in case of abnormalities, further ensuring the safe and stable operation of the power system.
