Description

Technical Field

[0001] This utility model relates to the field of low-voltage distribution cabinet technology, specifically a ventilated low-voltage distribution cabinet. Background Technology

[0002] The low-voltage distribution cabinet is used for power, lighting and power distribution energy conversion and control in a power distribution system with a rated current of AC 50Hz and a rated voltage of 380V.

[0003] A search revealed that patent application number 202320133360.3 discloses a ventilated low-voltage distribution cabinet, including a cabinet body containing electrical components, and two rotary ventilation pipes located at the corners of the front end of the cabinet body. The two rotary ventilation pipes are rotated by a rotary motor. Each rotary ventilation pipe has several through holes and is connected to an air inlet pipe and an air supply device via a rotary joint. The air supply device supplies air into the rotary ventilation pipes through the air inlet pipe, and the air is blown out through the through holes to a ventilation hole on the rear end face of the cabinet body. This device enables frequent air exchange between the low-voltage distribution cabinet cabinet and the outside air, while also promptly dissipating heat emitted by the components inside the cabinet, improving the stability of the electrical equipment and extending the service life of the low-voltage distribution cabinet.

[0004] The aforementioned application document achieves efficient heat dissipation for its internal components through the configuration of each component. It is an impact-type heat dissipation method that delivers external air to the inside for air cooling. However, the motor and fan need to be started for a long time, resulting in high power consumption and low overall practicality.

[0005] Therefore, we propose a ventilated low-voltage distribution cabinet. Utility Model Content
