Description

An outdoor distribution box for the State Grid project

technical field

The utility model relates to the technical field of outdoor power distribution boxes, in particular to an outdoor power distribution box for national grid projects.

Background technique

The temperature of the outdoor integrated distribution box due to the sun's irradiation in summer directly affects the operating data of the intelligent terminal host in the cabinet. The previous integrated distribution box used natural air cooling. The function of smart terminal equipment, the integrated distribution box adopts natural air cooling, and the internal temperature rises relatively slowly, which will cause the internal temperature of the distribution box to continue to rise. It will eventually affect the operating data of the smart terminal host, and now the fan is installed In rainy days, rainwater can easily enter the cabinet through the air inlet along with the air, causing damage to electrical equipment.

Utility model content

The purpose of the utility model is to disclose a comprehensive air distribution duct for the outdoor distribution box of the national grid project aiming at the technical defects existing in the prior art.

In order to realize the purpose of the utility model, the technical scheme that the utility model takes is:

An outdoor power distribution box for a national grid project, including a box body, a cabinet door is hinged on the box body, and a part of the box body is an incoming line room and an electrical room. Installing brackets are arranged between them, vents are formed on both sides of the box body, an air duct box is arranged outside the vents, the bottom of the air duct box communicates with the outside world, a fan is installed at the lower part of the air duct box, and the fan is installed below the vents.

Further, a filter screen is installed at the bottom of the air duct box.

Further, the air duct box outside the wire inlet room is an air intake duct box, and the air duct box outside the electrical room is an air duct box for outlet air.

Further, a partition is fixed by bolts between the installation bracket and the cabinet door, and an instrument control door is hinged on the partition.

Further, the bottom of the box is provided with cooling holes.

Further, a handle is installed on the cabinet door.

Compared with the prior art, the utility model has the advantages of:

By adding air duct boxes on both sides of the distribution box and cooperating with the internal fan, it can effectively prevent rainwater from entering the distribution box with the air driven by the fan while ensuring good heat dissipation of the distribution box.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Example 1

An outdoor power distribution box for a national grid project, including a box body 1, a cabinet door 2 is hinged on the box body 1, the interior of the box body 1 is divided into an incoming line room 3 and an electrical room 4, and the incoming line room 3 communicates with the electrical room 4, In addition, a mounting bracket 5 is provided between the wire inlet chamber 3 and the electrical chamber 4, and vents 6 are formed on both sides of the box body 1, and an air duct box 7 is arranged outside the vent opening 6, and the bottom of the air duct box 7 communicates with the outside world. A blower fan 8 is installed at the bottom of the case 7, and the blower blower 8 is installed below the air vent 6. The bottom of the air channel box 7 on both sides of the box body 1 is connected with the outside world, which ensures that the air in the distribution box can exchange with the outside world to achieve the effect of cooling and heat dissipation, and also prevents rainwater from entering the distribution box with the air driven by the fan 8 internal damage.

A filter screen 9 is installed at the bottom of the air duct box 7 . The filter screen 9 can block and reduce a part of dust in the air and on the ground from entering the distribution box, causing too much dust inside the distribution box to cause damage to internal instruments.

The air duct box 7 outside the wire inlet chamber 3 is an air intake duct box, and the air duct box 7 outside the electrical room 4 is an air outlet duct box. Because there are few electrical components on one side of the wire inlet room 3, even if a small amount of rainwater on the ground is sucked into the inside of the distribution box, it cannot reach the electrical room with more electrical components, which can further affect the electrical components inside the distribution box. to waterproof protection.

Between the mounting bracket 5 and the cabinet door 2, a dividing plate 10 is fixed by bolts, and an instrument control door 11 is hinged on the dividing plate 10 . The setting of the partition 10 makes it possible to separate the charged components from the operator during daily observation to protect the safety of the operator, and when debugging is required, the instrument controller 11 can be opened for debugging without removing the partition.

The bottom of the box body 1 is provided with cooling holes 12 . The heat dissipation holes 12 at the bottom of the box body 1 can further increase the heat dissipation effect of the distribution box.

A handle 13 is installed on the cabinet door 2 .

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these Improvement and retouching should also be regarded as the protection scope of the present utility model.
