Embodiment

[0023] An outdoor protective electrical cabinet with an active filtering device, including a rectangular parallelepiped housing 1 and a controller 5, the four side walls of the housing 1 are respectively provided with electric shutters 2 and light sensors 3, and the controller 5 is connected with the electric shutters respectively. The driving motor of 2 is connected with the light sensor 3,

[0024] Under normal circumstances, the four electric shutters 2 are all open, and when the light intensity detected by the light sensor 3 exceeds the set value, the controller 5 closes the electric shutter 2 on the side wall where the light sensor 3 is located.

[0025] The blades of the electric blinds 2 are photovoltaic blades connected with batteries, and the batteries are respectively connected with the controller 5 and the drive motor.

[0026] The electrical cabinet also includes a temperature and humidity sensor 6 and an exhaust fan 7 arranged in the casing 1, the temperature and ...

Abstract

The invention relates to an outdoor protection electrical cabinet of an active filtering device. The outdoor protection electrical cabinet comprises a cuboid shell (1) and also comprises a controller(5), wherein an electric shutter (2) and a light sensor (3) are arranged on each of four side walls of the shell (1), the controller (5) is connected with a driving motor of the electric shutter (2) and the light sensor (3), the four electric shutters (2) are opened in a normal condition, and the controller (5) is used for enabling the electric shutter (2) on the side wall where the light sensor (3) is located to be closed when light intensity detected by the light sensor (3) exceeds a setting value. Compared with the prior art, the interior of the electrical cabinet can be prevented from being exposed under strong light, the rising of an internal temperature is reduced, and a component is prevented from aging.

Description

technical field [0001] The invention relates to an electric cabinet, in particular to an outdoor protective electric cabinet of an active filtering device. Background technique [0002] The active filter device is a new type of special equipment for power harmonic control made of modern power electronics technology and digital signal processing technology based on high-speed DSP devices. It has high requirements for the working environment and usually needs to be placed in a special electrical cabinet. When the outdoor electrical cabinet is in an environment with strong light, the temperature is likely to rise, affecting the normal operation of the components, and the strong light is likely to cause aging of the active filter device in the electrical cabinet. It is necessary to take corresponding protective measures for the electrical cabinet. The Chinese patent with the application number 201521007021.2 discloses a solar electrical cabinet, which includes a housing, a nozz...
