Description
Technical Field
The invention relates to the technical field of controlling the air environment in a ring main unit.
Background
With the continuous expansion of the construction scale of the smart power grid and the popularization of local automatic remote control, the outdoor ring main unit is widely applied due to the advantages of small investment, short construction period, standardized production and the like. Because the cabinet body protective effect is limited, the environment is abominable, and wind and rain is exposed to the sun, ponding snow etc. and the environmental change acutely leads to the damage of electrical equipment easily.
In recent years, the space in the ring main unit is often very narrow along with the improvement of the ring main unit structure.
The standardized width of the ring main unit is only 1150mm, and after the width of the ring main unit is deducted, the distance is usually only about 100mm, so dead angles are easily generated in the traditional air supply mode, particularly, a fan is difficult to be sent to the opposite side of the ring main unit, and circulation is difficult to be formed in the ring main unit.
Therefore, an air supply mode which is suitable for the existing ring main unit with a narrow internal space needs to be found.
Disclosure of Invention
In order to achieve the purpose, the invention adopts the following technical scheme:
a dead-corner-free air supply system in a ring main unit comprises an outer main unit and an inner main unit, wherein the inner main unit is arranged in the outer main unit, and an air outlet is formed in the upper part of the outer main unit; the microenvironment controller is arranged on the side surface of the outer cabinet and supplies air to the outer cabinet through the fan; the air output of the fan is controlled by an intelligent control unit, and a control signal of the intelligent control unit comes from a sensor; the microenvironment controller comprises a shell and a fan; the shell is provided with an air inducing port for inducing air; the fan is arranged in the shell and used for sending the air introduced from the air inducing port into the outer cabinet from an air outlet of the fan; a secondary fan synchronously opened and closed with the fan is arranged inside the outer cabinet, and the direction of the air outlet flow of the secondary fan is the same as that of the air flow sent out by the fan; the secondary air fan is controlled by the intelligent control unit. The air flow sent by the fan can reach the position of the secondary fan, and the secondary fan and the air flow sent by the fan are exhausted in the same direction, so that circulation around the inner cabinet can be formed.
As a further improvement, the air outlet direction of the fan is adjustable and is controlled by the intelligent control unit. According to the needs, can control to arbitrary one side air-out.
As a further improvement, the fan is a horizontal fan. The horizontal fan can supply air on a long and narrow surface. In a narrow space, a vertical wide air zone can be formed by using the horizontal fan, the air flow is convenient to diffuse up and down, and the air supply dead angle is favorably eliminated.
As a further improvement, the secondary fan is a horizontal fan.
As a further improvement, the microenvironment controller is arranged on the outer side wall of the outer cabinet. Because the looped netowrk cabinet inner space is often very narrow and small, install the lateral wall at outer cabinet with microenvironment controller and can reduce the shared space of microenvironment controller self to the influence that the air flows in the looped netowrk cabinet, reach the purpose at further elimination dead angle.
The invention has the advantages that: 1. the method is suitable for the environment with narrow internal space of the ring main unit; 2. the temperature and the humidity of each space in the ring main unit are balanced, so that dead corners are eliminated, and condensation is eliminated from the source.

Detailed Description
In order to more clearly describe the technical contents of the present invention, the following further description is made in conjunction with fig. 1 to 2.
As shown in fig. 1 and 2, the ring main unit comprises an outer main unit 1 and an inner main unit 2, the inner main unit is installed inside the outer main unit 1, and an air outlet 11 is formed in the upper part of the outer main unit 1; the microenvironment controller 5 is arranged on the side surface of the outer cabinet 1 and supplies air to the outer cabinet 1 through the fan 52; the air output of the fan 52 is controlled by an intelligent control unit 55, and a control signal of the intelligent control unit 55 is derived from the sensor 7; the microenvironment controller 5 comprises a shell 51 and a fan 52; the shell 51 is provided with an air inducing port 53 for introducing air; the fan 52 is arranged in the shell 51 and is used for sending the air introduced from the air inlet 53 into the outer cabinet 1 from the air outlet of the fan 52; a secondary fan 6 which is synchronously opened and closed with the fan 52 is arranged inside the outer cabinet 1, and the direction of the air outlet flow of the secondary fan is the same as the direction of the air flow sent out by the fan; the secondary air fan 6 is controlled by an intelligent control unit 55. At the position where the airflow sent by the fan 52 can reach the secondary fan 6, the secondary fan 6 blows air in the same direction as the airflow sent by the fan 52, so as to ensure that a circulation flow surrounding the inner cabinet can be formed.
When air is supplied to one direction, airflow surrounding the inner cabinet 2 is formed in the ring main unit, but because the distance between the outer cabinet 1 and the inner cabinet 2 is very small, the airflow is greatly blocked, so that dead corners where a lot of airflows do not flow through are formed, and the dead corners can be different from other positions in temperature and humidity. By controlling the fan 52 to blow air to both sides, these dead corners can be effectively eliminated. When the air supply direction of the fan 52 is changed, the secondary fan 6 needs to output air in the same direction with the air flow sent by the fan 52, so as to ensure that a circulation flow surrounding the inner cabinet can be formed.
Two air supply modes can be adopted, firstly, air is supplied to one side, the dead angle at the moment is generated on the other side of the air outlet direction of the fan 52, air is supplied to the other side after the air is intermittently supplied for a period of time, and the purpose of eliminating the dead angle can be achieved.
The secondary fan 6 is installed on one side far away from the fan 52 in fig. 1, when the fan 52 supplies air to one direction, the phenomenon of weakness appears when the secondary fan reaches the position of the secondary fan 6, and the turbulent flow appears in the latter half of the period, which can lead to dead air supply. After the secondary fan 6 and the fan 52 are synchronously started, relay type air supply can be effectively formed, and dead angles are prevented. The secondary fan 6 may be installed in more than one direction, and the air supply direction must be consistent with the air supply direction of the fan 52.
As shown in fig. 2, the fan 52 is a horizontal fan, and can generate an air duct with a large vertical span, thereby effectively eliminating air supply dead corners.
