Description
Technical Field
[0001] The utility model relates to the technical field of triple frequency generators, in particular to a triple frequency generator with a dustproof structure. Background Art
[0002] According to national test standards, the induced test voltage of power transformers and voltage transformers is approximately 2-3 times the maximum working phase voltage. As we all know, at rated frequency and rated voltage, the iron core of the transformer is close to saturation. If a test voltage greater than the rated voltage is applied at both ends of the transformer winding using an industrial frequency power supply, the no-load excitation current will increase sharply to an unacceptable level. From the relationship between the induced potential, it can be seen that in order to apply a test voltage greater than the rated voltage without saturating the iron core, the power supply frequency can be increased. A power generator greater than the double frequency must be used. The triple frequency generator is used for test products such as power transformers and voltage transformers. In addition to external construction frequency high voltage tests on the main insulation of fully insulated transformers, induced high voltage tests are also required on the longitudinal insulation of the transformer and the main insulation of semi-insulated transformers.

In addition, the interior of the triple frequency generator electric control console and electric control box does not have good dustproof and dustproof capabilities. Therefore, we have made improvements to this and proposed a triple frequency generator with a dustproof structure. Utility Model Content
