Problems solved by technology

Although the transformer is also designed with a waterproof structure, the snow and sand accumulated for a long time will turn into snow water when the isolation transformer is working, which will cause the insulation performance of the isolation transformer coil to gradually decrease, and may eventually cause the isolation transformer to burn out.

Abstract

The invention belongs to the technical field of electrical equipment box structure, and in particular relates to a wind and sand-proof double-layer louver door panel for a transformer box, including a louver panel and an inner baffle; Window; the inner baffle is set on the other side of the louver, and an interlayer is formed between the inner baffle and the louver; at the same time, there are several heat dissipation holes arranged on the inner baffle, and the heat dissipation holes and heat dissipation windows are arranged alternately to form a labyrinth ventilation structure. It effectively meets the ventilation and heat dissipation requirements of the box, and prevents wind and sand from entering the inside of the box.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment box structures, and relates to a wind-and-sand-proof shutter, in particular to a wind-and-sand-proof double-layer shutter door panel for a transformer box. Background technique [0002] In addition to two inverter modules, the inverter box under the 25G / T railway passenger car (DC600V) needs to be equipped with a 15kVA isolation transformer. Since the heat of the transformer is high when it is working at full load, the installation area of ​​the inverter module is designed as a sealed structure (IP54). figure 1 ‐3), specifically: the box where the isolation transformer is placed is relatively independent from the inverter module area, the backplane adopts a grid structure, and two rows of Φ6 small round holes are set at the bottom to form a ventilation channel for heat dissipation. [0003] Furthermore, for the electrical equipment that generates a lot of heat under the vehicle, acco...
