High-low voltage electrical equipment with ventilation and moisture-proof structure

Abstract

The invention belongs to the technical field of electrical equipment, in particular to high-low-voltage electrical equipment with a ventilation damp-proof structure. The high-low-voltage electrical equipment comprises an equipment body and a placement groove, a mounting plate is fixed in the equipment body, a moisture absorption plate is mounted in the mounting plate, a circuit board is arranged outside the moisture absorption plate, a substrate is arranged on the side of the circuit board, a sliding groove is formed in the base plate, a sliding block is arranged in the sliding groove, a firstspring is arranged on the outer side of the sliding groove, a clamping column is connected to the top of the first spring, a bayonet is formed in the outer portion of the clamping column, a fixing shaft is arranged on the outer side of the base plate, and a connecting arm is arranged on the outer side of the fixing shaft. The high-low voltage electrical equipment with the ventilation and moisture-proof structure is provided with the fan, airflow generated by the fan during working can act on the surface of the flow guide plate, so that the flow guide plate rotates to guide the airflow, the airflow is dispersed more uniformly, and the ventilation and heat dissipation effects of the fan are improved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to high and low voltage electrical equipment with a ventilation and moisture-proof structure. Background technique [0002] High and low voltage electrical equipment is an electrical device that can be installed in an integrated manner for various high and low voltage electrical equipment. In order to ensure the stability of each component during installation and use, and ensure the normal service life of the components, this case designs a ventilation system. High and low voltage electrical equipment with moisture-proof structure. [0003] Most of the existing high-voltage and low-voltage electrical equipment on the market has poor ventilation and dehumidification capabilities. The air humidity inside the equipment is relatively high, which is easy to cause corrosion to the components, which reduces the service life of the components. The inspection and maintenance of...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a high-voltage and low-voltage electrical equipment with a ventilation and moisture-proof structure, so as to solve the problem that most of the existing high-voltage and low-voltage electrical equipment on the market proposed in the background technology have poor heat dissipation capabilities, and at the same time, the moisture inside the equipment is not sufficient. To clean up in time, the long-term work of the components in the hot and humid environment is likely to reduce the service life. At the same time, the space inside the equipment is limited, and the internal circuit board cannot be pulled out, which brings inconvenience to the user's use and maintenance.
