Abstract

The invention relates to the technical field of safety equipment facilities of power equipment, in particular to a cross-flow type cooling fan with a damping function for a dry-type transformer, and solves the technical problem that an existing cooling fan cannot be independently disposed when a high-voltage coil and a low-voltage coil of a unit transformer have cooling priority in the prior art. The fan specifically comprises a body, wherein an air volume adjusting assembly can periodically move to a first air outlet of the body, so that the air volume of the first air outlet can obtain a first limit state and a second limit state; the second air outlet communicates with the first air outlet; an air volume adjusting movement mechanism is used for driving the air volume adjusting assembly to periodically move in the cross section direction of the first air outlet; and the air volume adjusting assembly comprises an air channel shielding structure. The technical scheme can provide larger air volume, is variable in air volume, is lower in noise, and is suitable for power consumers such as transformer substations, residential quarters, commercial mansions, industrial enterprises and the like and some areas with severe environments.

Description

technical field [0001] The invention relates to the technical field of power equipment safety equipment and facilities, in particular to a cross-flow cooling fan for a dry-type transformer with a damping function. Background technique [0002] The cross-flow cooling fan for dry-type transformers with shock absorption function is a cross-flow fan specially used for cooling dry-type transformers and has no guide vanes at the air inlet and the first air outlet. In the prior art, due to the dry-type The specific structure of the primary low-voltage coil of the high-voltage coil of the transformer and the corresponding cooling requirements. The corresponding cross-flow cooling fan adopts a special single-phase or three-phase low-power induction asynchronous motor, a cross-flow impeller, a casing and an air guide device. , the corresponding implementation standard is B / T 8971-2013. [0003] In the prior art, the typical type of cross-flow cooling fan for dry-type transformers wit...
