[0023] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0024] See also Figure 1-6 , a low-voltage integrated distribution box, comprising a box body 1; the front and rear of the box body 1 are both opened, and the front and rear of the box body 1 are respectively provided with a front box door 2 and a rear box door 201, and the front box door 2 and the rear box door 201 are both rotatably connected to the box body 1 through hinges;

[0025] The existing low-voltage integrated distribution box has only one door for maintenance, which is very inconvenient. In this solution, a front box door 2 and a rear box door 201 are arranged at the front and rear of the box body 1. When opening for maintenance, the front and rear of the box body 1 can be opened, thereby facilitating maintenance;

[0026] The box 1 is provided with a reactive power compensation unit room 101, an incoming line unit room 102, an emergency interface unit room 103 and a substation intelligent fusion terminal unit room 104.

[0027] The front ends of the reactive power compensation unit room 101, the incoming line unit room 102, the emergency interface unit room 103 and the intelligent fusion terminal unit room 104 of the substation are each provided with an independent front door 2, the incoming line unit room 102, the emergency interface unit room 103 and the intelligent fusion terminal unit room 104 of the substation share a rear door 201, and the rear side of the reactive power compensation unit room 101 is provided with a rear door 201;

[0028] The left and right side walls of the box body 1 are both provided with air inlets 3, wherein an air inlet shell 301 is installed at the inside of the box body 1 corresponding to the air inlet 3, the outer opening of the air inlet shell 301 is provided and fits with the air inlet 3, the air inlet shell 301 is fixedly installed on the side wall of the box body 1, the air inlet shell 301 includes an air inlet portion 302 and an air exhaust portion 303, wherein the air inlet portion 302 is provided corresponding to the air inlet 3, and the bottom of the air exhaust portion 303 is higher than the bottom of the air inlet portion 303, and a transition air outlet 304 is provided on the side of the air inlet portion 302;

[0029] The external airflow enters the air inlet 302 from the air inlet 3, then enters the air outlet 303, and then enters the interior of the box 1 from the transition seal 304, which is used to cool the equipment inside the distribution box;

[0030] The utility model has the advantage of using the air inlet shell 301 that, when the air inlet 3 is taking in air, water droplets may enter from the air inlet 3, and by using an air inlet shell whose bottom of the exhaust part 303 is higher than the air inlet 303, the water droplets will stay at the bottom of the air inlet 302 and cannot climb to the exhaust part 303, thereby isolating the entry of water droplets;

[0031] At the same time, the bottom of the air inlet 302 is flush with the bottom of the air inlet 3, and the water droplets entering the air inlet 302 will be collected in the air inlet 302 and then discharged from the bottom of the air inlet 3;

[0032] The top of the box body 1 is also provided with a top cover 4, which is a rectangular shell with an opening at the bottom. The side of the top cover 4 is provided with a plurality of exhaust holes 403, and the bottom of the top cover 4 is also provided with a top cover bottom plate 401, on which an exhaust fan 402 is fixedly installed;

[0033] When the utility model is used, the exhaust fan is started, and the external air enters into the box body 1 through the air inlet shell 3. The air inlet shell 3 can intercept external water droplets, and the air flow cools down the equipment in the box body. Then, the air flow passes through the exhaust fan, rises and reaches the top plate portion 404 and the inclined plate portion 405, flows toward the outside of the inclined plate portion 405, and is finally discharged from the exhaust hole 403 on the side of the top cover 4.

[0034] At the same time, a waterproof elbow 5 for the incoming and outgoing cables to pass through is also provided on the side of the box body 1. A through hole for the waterproof elbow 5 to pass through is opened on the box body 1, and a waterproof elbow nut 501 is provided on the inner side of the through hole of the box body 1. One end of the waterproof elbow 2 passes through the through hole of the box body 1 and is threadedly connected with the waterproof elbow nut 501 located inside the box body 1. The waterproof elbow 5 is sealed and connected to the outer wall of the box body 1. Since the waterproof elbow directly passes through the through hole on the cabinet body and is then tightened with the waterproof elbow nut, the original welding of the waterproof elbow 5 and the cabinet body is avoided. The waterproof elbow and the waterproof elbow nut are tightened, which simplifies the processing technology and is simple to assemble.
