Dotted terminal identifier of high and low frequency transformer winding

Abstract

The invention provides a dotted terminal identifier of a high and low frequency transformer winding. The dotted terminal identifier of the high and low frequency transformer winding is characterized by comprising a 6V direct current power supply, an electromagnetic signal input circuit, a one-way controllable silicon triggering circuit and an indicating circuit. As instruments for identifying dotted terminals of transformer coil windings are hard to find on the market, so that the dotted terminal identifier of the high and low frequency transformer winding is very necessary to design and make. According to the invention, an identifier circuit formed by elements such as controllable silicon is adopted. Through the adoption of the dotted terminal identifier provided by the invention, the dotted terminal or different terminal of the high frequency transformer and the low frequency transformer can be rapidly identified without distinguishing the powers of the transformers; and both boosting transformers and step-down transformers can be both identified. According to the invention, a problem in identifying the dotted terminal or the different terminals of primary coils and secondary coils of the low frequency transformer coils or the high frequency transformer coils can be conveniently solved; and the dotted terminal identifier is a special testing tool for the transformer, which is featured with accurate identification result and easy popularization.

Description

Technical field [0001] The invention belongs to the technical field of transformers, and relates to an end recognizer of the same name in a winding of a high and low frequency transformer. Background technique [0002] Some circuits such as transformers, couplings or oscillations need to be clear about the same-named or different-named ends of the primary and secondary coils of the low-frequency transformer or high-frequency transformer coil. Sometimes it is necessary to identify the same-named ends of multiple windings of the transformer in electronic production, maintenance and replacement. Very troublesome. It is difficult to find instruments on the market for identifying the same-name end of a transformer coil winding, so it is necessary to design and manufacture a transformer coil winding same-name end recognizer. The present invention uses an identifier circuit composed of thyristor and other components. It can be used to quickly identify the same-named or different-named ...
