Anti-dust ventilation waterproof device for power distribution cabinet

Abstract

The invention discloses an anti-dust ventilation waterproof device for a power distribution cabinet. The anti-dust ventilation waterproof device comprises a power distribution cabinet body, a vacuum cleaner, a dryer box, an exhaust fan, a filter screen, a flashing, a sunshade, a camera, an LED lamp, a temperature sensor and a humidity sensor. The bottom end of the power distribution cabinet body is provided with a damping plate and a moisture-proof plate. The power distribution cabinet body is provided internally with the vacuum cleaner. The vacuum cleaner communicates with a suction inlet through a suction duct. The power distribution cabinet body is provided internally with the exhaust fan. The filter screen is disposed on the side wall of the power distribution cabinet body. The rear side of the exhaust fan is provided with the dryer box. The side wall of the power distribution cabinet body is provided with the flashing. The top end of the power distribution cabinet body is provided with a support. The sunshade is disposed on the support. The inner wall at the top end of the power distribution cabinet body is provided with the camera. The top end of the power distribution cabinet body is provided with the LED lamp. The inner wall of the power distribution cabinet body is provided with the temperature sensor and the humidity sensor. The invention reduces component aging caused by over high temperature, extends the service life, prevents the dust and moisture from affecting the operation of the electronic components, and is simple in structure, easy to use and conducive to promotion.

Description

technical field [0001] The invention relates to electric equipment, in particular to a dustproof, ventilating and waterproof device for a power distribution cabinet. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. The high-voltage power distribution cabinet is generally sealed due to the ...

AI Technical Summary

Problems solved by technology

The high-voltage power distribution cabinet is generally sealed due to the consideration of the environment and safety needs. The high-voltage power distribution cabinet has the characteristics of long-term continuous operation. The high-voltage power distribution cabinet is generally placed in the open air, so the external weather conditions may affect the interior of the power distribution cabinet environment, because the electrical components inside the power distribution cabinet operate continuously for a long time, the electrical devices in the cabinet will generate heat during operation, and the heat will affect the rubber insulating material in the power distribution cabinet, resulting in accelerated aging and insulation Performance decline, when severe aging may lead to short circuit of internal electrical components, resulting in accidents, so monitoring the temperature in the high-voltage power distribution cabinet and cooling its interior is conducive to the safe operation of electrical equipment in the power distribution cabinet

Due to the self-loss and heating of the internal electrical components in the outdoor power distribution cabinet and the influence of environmental factors such as sunlight, the temperature inside the cabinet will rise, and in severe cases it will cause the circuit breaker to trip and short circuit

At this stage, there is no good way to effectively detect the internal temperature of the high-voltage power distribution cabinet. Only when a fault occurs, the cabinet is opened for maintenance, which will cause power outages and bring great inconvenience to people's lives.
