Mining dry-type transformer power connection cabinet

Abstract

The invention belongs to the technical field of dry-type transformer power connection cabinets, and particularly relates to a mining dry-type transformer power connection cabinet which comprises a cabinet body, a frame is arranged on the inner surface wall of the cabinet body, an empty groove is formed in the frame, a sponge layer is arranged in the empty groove, a clamping groove is formed in the outer surface wall of the frame, and a shell is arranged on the front surface wall of the frame. Clamping blocks matched with the clamping grooves are arranged on the inner surface wall of the shell, and a first partition plate and a second partition plate are arranged in the cabinet body. According to the invention, the sponge layer is additionally arranged in the frame, so that when the cabinet body is used, the sponge layer can adsorb moisture in air entering the cabinet body, and at the same time, too heavy humid gas is prevented from entering the cabinet body in rainy days, so that the circuit is not damaged, and a moisture-proof effect is achieved; and by additionally arranging the wire bunching plate, the wire bunching port and the wire bunching groove, the wire bunching plate, the wire bunching port and the wire bunching groove can be used for arranging lines, so that the lines are not disordered in the cabinet body.

Description

technical field [0001] The invention relates to the technical field of dry-type transformer connection cabinets, in particular to a mine-used dry-type transformer connection cabinet. Background technique [0002] Dry-type transformers are widely used in places such as local lighting, high-rise buildings, airports, and wharf CNC machinery and equipment. Simply put, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil; cooling methods are divided into natural air cooling ( AN) and forced air cooling (AF). When naturally air-cooled, the transformer can operate continuously for a long time at the rated capacity. When forced air cooling, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation, or emergency accident overload operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operation state, so it should n...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a mine-used dry-type transformer connection cabinet, which solves the problem of the moisture in the air entering the cabinet body when the cabinet body is in use, and the excessively heavy humid gas when it rains It is easy to enter the cabinet body, which makes it easy to cause damage to the lines and cannot play the role of moisture-proof. In addition, when there are multiple lines inside the cabinet body, the lines cannot be arranged, making the lines appear messy in the cabinet. At the same time, it is not possible to distinguish the lines well, which may easily lead to the defect of accidents caused by maintenance personnel connecting wrong lines.
