Transformer iron core mute testing system

Abstract

The invention relates to the technical field of iron core mute testing, in particular to a transformer iron core mute testing system. The system comprises a mute room, one side of the mute room is provided with a channel for a transformer iron core to go in and out, a soundproof door is arranged at a channel opening, transportation rails are arranged inside and outside the channel of the mute room, and a transportation trolley is arranged on the transportation rails and can move along the transportation rails to go in and out of the mute room; a plurality of sound collector fixing columns are arranged in the mute room and are uniformly distributed along the side wall of the mute room, and sound collectors are fixed on the sound collector fixing columns. A room with a low internal environment decibel can be isolated in a noisy factory production environment so as to be used for the noise test of the transformer iron core, the noise test can be rapidly and safely carried out on the iron cores of different specifications in a short time, and a relatively accurate testing result can be obtained.

Description

technical field [0001] The invention relates to the technical field of iron core mute testing, in particular to a transformer iron core quiet test system. Background technique [0002] In the prior art, at home and abroad, the assembled transformer core is usually tested directly with a hand-held decibel meter after being energized on site, or the core is placed in a sealed device for testing. Although the traditional transformer core silent test method is convenient and quick, it ignores the impact of environmental noise on the test results, and the test instruments are too simple, which will cause a large deviation between the test results and the real value, and cannot be used as authoritative test data. Contents of the invention [0003] Aiming at the shortcomings in the above-mentioned existing production technology, the present application provides a transformer core silent test system, which can quickly and safely perform noise tests on various types of cores with d...
