technical field

The utility model relates to the technical field of power supplies, in particular to an outdoor power supply device. the

Background technique

The outdoor cabinet not only needs to meet the waterproof and dustproof requirements of the whole machine, but also needs to arrange the internal electrical components reasonably. At present, most of the power supply cabinets used outdoors have problems of large size, heat dissipation and maintenance. The main manifestations are as follows: 1. There are many components and the unreasonable placement of components leads to a large cabinet volume; 2. Due to the sealing of all components, it is inconvenient to install and maintain the components; 3. The functional components are not partitioned and interfere with each other . 4. Since the devices are basically sealed in the box, the heat dissipation effect is poor. the

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application. the

As shown in Figure 1, one embodiment of the present utility model comprises a cabinet body 1, and the first dividing plate 2 is arranged in the cabinet body 1 and divides the cabinet body into a front cavity and a rear cavity, and the lower part of the front cavity A second partition 3 is provided to divide the lower portion of the front cavity into a front space and a rear space. the

The cabinet body is divided into three layers by using two partitions. Both partitions can be used to place components, which is convenient for component placement, saves cabinet space, and the cabinet is small in size. the

Further, in other embodiments, a DC circuit breaker and an AC circuit breaker are placed in the front space, a contactor, a filter and an inverter module are placed in the rear space, and a transformer and reactor. Use partitions to divide the cabinet into three layers of space. The first layer is used as a power distribution layer for placing AC circuit breakers and DC circuit breakers. The second layer is a control filter layer for placing contactors, filters and inverters. Modules, etc., the third layer is the magnetic element layer, which is used to place transformers and reactors, etc. The DC circuit breaker and AC circuit breaker can also be placed in the rear space, and the contactor, filter and inverter module can also be placed in the front space. In this way, the electrical components are divided into three areas according to their functions. This partition configuration not only speeds up the assembly speed, but also strengthens the ability of electromagnetic shielding. the

During actual installation, the AC circuit breaker and DC circuit breaker can be installed on the second partition 3 , and the contactor, filter and inverter module can be installed on the first partition 2 . the

Further, the second partition is composed of an air-opening installation board 4 and a distribution board 5 arranged up and down. When installing, you can install the components on the partition first, and then fix the partition and the cabinet. When disassembling, you can also remove the partition as a whole first, and then maintain the components. The second partition consists of two Composed of blocks, it is easier to install and maintain. During actual assembly, a DC circuit breaker and an AC circuit breaker can be placed on the air switch mounting plate 4 , and DC input and DC output copper bars can be placed on the distribution board 5 . the

Further, a PCB board is installed on the side of the second partition 3 facing the cabinet door. In actual assembly, the PCB board can be installed on the open mounting plate 4, so that the front maintenance of the PCB board can be realized without disassembling any door panels or panels. the

Further, the upper part of the front cavity is provided with a fan, and the fan is an axial flow fan. Since the components placed in the front cavity are all waterproof and dustproof components, the front cavity is often required to be a closed cavity , so the heat dissipation problem is more critical. Therefore, a fan is arranged on the upper part of the front cavity. The position of the fan is shown in Figure 2. The axial direction of the fan 6 is at an angle of 35 degrees to the vertical direction. When the fan is running, the air circulates in the airtight front cavity to avoid the front Heat buildup occurs on components inside the cavity. In order to facilitate air circulation, a certain space is left above and below the second partition and the components installed on it as air circulation channels. Preferably, the bottom space should be as large as possible, so that more cold air can be stored , so that the hot air in the upper part and the cold air in the bottom space can fully realize the exchange and circulation, and the internal air finally exchanges heat with the outside through the box itself, which meets the heat dissipation requirements of the closed box. the
