Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Directional terms mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inner", "outer", "side", etc., are only used to refer to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but are not used to limit the present invention.

[0026] The utility model provides a novel outdoor junction box embodiment 1, see Figure 1 and Figure 2 The novel outdoor junction cabinet comprises: a cabinet body 1, a cabinet door 2, an incoming line chamber 6, an outgoing line chamber 8, a cable chamber 7, an energy storage display mechanism 9, a microcomputer protection device 10, an air inlet and outlet 3 arranged on the front of the cabinet body 1, a bridge 4 arranged above the top cover of the cabinet body 1, an inspection cover 5 arranged on the top surface of the bridge, and a plurality of protective components. The air inlet and outlet 3 can also be arranged on the side or back of the cabinet body 1, and its position is not limited here.

[0027] from Figure 2 It can be seen that the incoming line chamber 6, the outgoing line chamber 8, and the cable chamber 7 are all separated and arranged in the frame of the cabinet 1. There are multiple outgoing line chambers 8, and when any one of them fails, it does not affect the continued operation of other outgoing line chambers 8. Therefore, the separated arrangement can facilitate the work and maintenance process.

[0028] See also Figure 3-Figure 5 The plurality of protection components include: a first protection component 13 located at the joint between the cabinet doors 2, a second protection component 14 located at the connection between the bridge frame 4 and the top cover of the cabinet body 1, and a third protection component 15 located at the connection between the bridge frame 4 and the inspection cover plate 5.

[0029] See Figure 3 The first protection component 13 includes: a U-shaped waterproof groove 131 provided at the mating position, and a first sealing strip 132 provided at the side of the waterproof groove 131. Since the novel outdoor junction cabinet is used outdoors, water seepage or other gas intrusion may occur at the mating position of the cabinet doors 2. By adding the U-shaped waterproof groove 131 and the first sealing strip 132, water molecules, gas molecules, etc. can be prevented from infiltrating, thereby improving the protection level of the novel outdoor junction cabinet.

[0030] See Figure 4 The bridge frame 4 is provided with a first connecting member at the connection between the bridge frame 4 and the top cover of the cabinet 1. The first connecting member preferably adopts a connecting mechanism composed of a hexagon socket screw 141 and a rivet nut 142, which is used to connect the bridge frame 4 with the top cover of the cabinet 1, so that the bridge frame 4 is fixedly installed on the top of the cabinet 1. If other conventional mechanisms with a connecting function are adopted, they are also within the protection scope of the present utility model.

[0031] In order to achieve better fixed installation of the bridge 4, the present embodiment is provided with a bridge internal welding flange 143 and a Z-shaped flange 145, the bridge internal welding flange 143 is fixedly welded to the bridge 4, the Z-shaped flange 145 is fixedly welded to the top cover of the cabinet 1, and the first connecting member penetrates the bridge internal welding flange 143 and the Z-shaped flange 145, thereby achieving fixed installation of the bridge 4 and the top of the cabinet 1. Among them, the second protective component 14 includes: a first full weld 146 provided at the gap between the Z-shaped flange 145 and the top cover, and a second sealing strip 144 provided at the gap between the bridge internal welding flange 143 and the Z-shaped flange 145. Since the new outdoor junction cabinet is used outdoors, and the bridge 4 and the cabinet 1 are not an integrally formed structure, water seepage, wind and sand invasion, etc. are prone to occur at the connection between the bridge 4 and the top cover of the cabinet 1. By adding the second protective component, the protection level of the new outdoor junction cabinet can be further improved.

[0032] See Figure 5 A second connecting member is provided at the connection between the bridge frame 4 and the inspection cover plate 5; the second connecting member preferably adopts a connecting mechanism composed of a hexagon socket head screw 151 and a rivet nut 152, which is used to connect the bridge frame 4 to the inspection cover plate 5. If other conventional mechanisms with a connecting function are adopted, they are also within the protection scope of the present utility model.

[0033] In order to realize the connection between the inspection cover plate 5 and the bridge, a U-shaped flange 153 is provided in this embodiment, and the U-shaped flange 153 is fixedly welded to the inside of the bridge 4, and the second connecting member passes through the inspection cover plate 5 and the U-shaped flange 153, so as to realize the fixed connection between the inspection cover plate 5 and the bridge 4. Among them, the third protective component includes: a third sealing strip 154 ​​provided at the gap between the U-shaped flange 153 and the inspection cover plate 5, and provided at the gap between the second connecting member and the inspection cover plate 5, and a second full weld 155 provided at the gap between the U-shaped flange 153 and the bridge 4. Similarly, since the new outdoor junction cabinet is used outdoors, and the bridge 4 and the inspection cover plate 5 are not an integrated structure, water seepage, wind and sand invasion, etc. are prone to occur at the connection between the two. By adding the third protective component, the protection level of the new outdoor junction cabinet can be further improved.

[0034] In this embodiment, the energy storage display mechanism 9 is composed of a plurality of energy storage indicating devices, which can respectively indicate the energy storage conditions of the incoming line chamber 6, the cable chamber 7, the outgoing line chamber 8, etc., so that the user can check the energy storage conditions at any time.

[0035] In this embodiment, the microcomputer protection device 10 includes: a control module, a communication module, and a display module. The microcomputer protection device 10 integrates the functions of a communication management machine, an optical fiber switch, and measurement, control, and protection, and is responsible for collecting and transmitting data information of equipment such as box transformers, junction boxes, and inverters in the new outdoor junction cabinet, and accesses the booster station through a self-healing ring optical fiber Ethernet to achieve remote control and automatic monitoring of the box transformer by the electric field booster station. Therefore, the operator only needs to remotely refer to the parameters to know the operation status of the new outdoor junction cabinet.

[0036] In this embodiment, the microcomputer protection device also has the function of three-stage current protection, namely: current quick-break protection, time-limited quick-break protection, and time-limited overcurrent protection. The current and time setting values ​​of each stage can be pre-set by the operator in the control module. When the corresponding protection pressure plate is put into operation, when the current of any phase is greater than the set value, it will act on the trip outlet after a delay, and the device will save and display the event record. Therefore, when the new outdoor junction cabinet has an abnormality or failure, the operator can also obtain information in time, thereby improving the efficiency of fault handling.

[0037] Through the above implementation, the protection level of the new outdoor junction box is greatly improved, so that its protection level reaches IP54, and it can be used in ordinary outdoor environments or even harsh outdoor environments (deserts, mountains, Gobi deserts, etc.), broadening the application scenarios of the junction box; another invention is that the new outdoor junction box is further equipped with the microcomputer protection device 10, thereby improving the degree of intelligence and automation.

[0038] In order to achieve the above-mentioned purpose, the present invention also provides a second embodiment of a new outdoor combiner cabinet, which is improved on the basis of the first embodiment. The improvement is that the new outdoor combiner cabinet also includes: a base; the base is arranged at the bottom of the cabinet body.

[0039] In this embodiment, the base support 11 includes a base frame and a support frame; the base frame is two long strip-shaped folding structures, and its length is consistent with the length of the long side of the bottom surface of the cabinet body 1; the support frame is two long strip structures, which are used to support and connect the two base frames, and its length is consistent with the distance between the two base frames. In addition to the structure described in the above embodiment, the base support 11 can also adopt other structures that support and lift the height difference between the bottom surface of the new outdoor junction cabinet and the ground; the present utility model does not limit the structure of the base support 11.

[0040] Since conventional junction cabinets are not provided with a base 11, when assembling or repairing, the junction cabinet needs to be lifted and placed on an external shelf, which is a bit troublesome to operate. In this embodiment, by adding the base 11, the assembly and maintenance of the new outdoor junction cabinet can be achieved without an external shelf, thereby improving the practical performance of the new outdoor junction cabinet.

[0041] In order to achieve the above-mentioned purpose, the utility model also provides a third embodiment of an outdoor junction cabinet, and the third embodiment is improved on the basis of the second embodiment, and the improvement is that the outdoor junction cabinet also includes: a fan 12. In this embodiment, the fan 12 is preferably arranged on the front of the cabinet 1. In actual use or design, the fan 12 can also be arranged on the side, back, etc. of the cabinet 1. The utility model does not limit the specific setting position of the fan 12, as long as it does not affect the use function of the new outdoor junction cabinet.

[0042] In this embodiment, the number of the fans 12 is one, two, or more than two. Figure 1 In this embodiment, the number of fans 12 preferably used is three, which can not only control the cost but also improve the temperature rise performance of the new outdoor junction cabinet. In this embodiment, the fan 12 preferably uses a high-power fan, and its wind speed can be as high as 1304m 3 / h, thereby further improving the heat dissipation process of the product.

[0043] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0044] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
