The invention discloses a device capable of adjusting inductance value, and relates to the technical field of electrical equipment withstand voltage tests. The device solves the technical problem that the inductance value cannot be adjusted preciously in the prior art. At least two or more than two electric reactors are adopted, and the electric reactors are placed in a laminated manner mutually; each electric reactor comprises an electric reactor body, a handle is arranged on the electric reactor body, a supporting adjusting mechanism is arranged on the handle, and the supporting adjusting mechanism can be used for adjusting the distance between the electric reactors placed in the laminated manner, so that the adjustment of the inductance value is realized. After the hollow electric reactors are serially connected and are placed in the laminated manner, linear adjustment of the inductance value is realized by adjusting the distance between the electric reactors and using the mutual inductance phenomenon of the electric reactors, namely the closer the distance is, the greater the mutual inductance is, the farther the distance is, the smaller the mutual inductance is, so that the technical field that the inductance value cannot be adjusted preciously in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of withstand voltage test of electric equipment, in particular to a device capable of adjusting inductance. Background technique [0002] Power equipment handover or preventive tests require high-voltage withstand voltage tests. Air-core reactors are used for compensation during the test. In order to facilitate manufacturing and use, multiple air-core reactors are often stacked in series, but stacked in series The final inductance is a fixed value. After adding or subtracting an air-core reactor, the inductance changes greatly, and it is often difficult to achieve accurate inductance. Contents of the invention [0003] The invention provides a device capable of adjusting the inductance, which is used to solve the technical problem that the inductance cannot be precisely adjusted in the prior art. [0004] In order to solve the above problems, the present invention adopts the following technical solutions ...
