Intelligent power distribution cabinet with efficient heat dissipation

Abstract

The invention relates to an intelligent power distribution cabinet with high-efficiency heat dissipation, which includes a main body, a switch door, two dust suction mechanisms and two air transmission mechanisms, and a handle, a display screen, several indicator lights and several control buttons are arranged on the switch door , the dust suction mechanism includes a first motor, a buffer block, two poles and several dust suction units, the dust suction unit includes a frame, a collar, a connecting rod, a dust suction block and a heat dissipation pipe, and the air transmission mechanism includes a bottom plate, a water tank, a drying Box, air guide box, first air pipe, cover plate, second air pipe and third air pipe, this intelligent power distribution cabinet with efficient heat dissipation absorbs the dust on the inner wall of the heat dissipation pipe through the dust suction mechanism to prevent blockage and affect the hot air discharge, so as to ensure efficient heat dissipation performance, not only that, in the voltage stabilizing circuit, the current limiting terminal of the second integrated circuit U2 is connected to the ground terminal through the second resistor R2, which limits the size of the current and ensures the stability of the output terminal Since the model of the second integrated circuit U2 is LT3086, the output voltage stability of the circuit is good, the pressure difference is small and the working noise is small, which further improves the practicability and market competitiveness of the device, and greatly improves the equipment. practicality.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an intelligent power distribution cabinet with high-efficiency heat dissipation. Background technique [0002] Power distribution cabinet is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment, forms low-voltage distribution equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch, and the circuit can be cut off or alarmed by means of a protective device in case of failure or abnormal operation. The power distribution cabinet can also display various parameters in operation with the help of measuring instruments, and can also adjust some electrical parameters, and prompt or send out signals for deviations from normal working conditions through indicator lights and speakers.

Problems solved by technology

[0003] In order to make the circuit components inside the power distribution cabinet work in a suitable temperature environment, there are usually several cooling vents on the side panels of the power distribution cabinet for ventilation and heat dissipation, but these cooling vents are simple in design and poor in cooling effect , just passively wait for the hot air to flow out from the heat dissipation port through the opening. Due to the limited amount of hot air flowing out per unit time, the heat dissipation effect is not good. When the temperature in the external environment is also high, the temperature difference between the internal and external environments is small, resulting The air circulation is poor, not only that, after the long-term operation of the power distribution cabinet, dust and debris are usually adsorbed on the heat dissipation port, resulting in poor air circulation, and it will also cause blockage when running along. The noise is large, which not only affects the stability of the voltage output, but also has a large voltage difference, which makes the voltage stabilization effect poor, thereby further reducing the heat dissipation performance of the power distribution cabinet
