Abstract

The invention discloses a transformer primary and secondary coil homonymous terminal and synonym terminal recognition device. The transformer primary and secondary coil homonymous terminal and synonym terminal recognition device is characterized by comprising a 6V direct current power supply, an electromagnetic signal input circuit, a one-way controllable silicon triggering and amplitude limiting circuit and a detecting and indication circuit. Primary and secondary homonymous terminals and synonym terminals of some transformers, coupling coils or oscillating coils need to be known clearly. Sometimes, the recognition of homonymous terminals of a plurality of windings of the transformer is troublesome during the process of electric production and transformer maintenance and replacement. A dedicated instrument for detecting the homonymous terminals of the windings of the transformer does not exist in a market so that designing and manufacturing the transformer primary and secondary coil homonymous terminal and synonym terminal recognition device is quite necessary. A recognition circuit is composed by utilizing elements of one-way controllable silicon and the like so that homonymous terminals or synonym terminals of high-frequency and low-frequency transformers can be rapidly recognized, magnitude of power of the transformer does not need to be distinguished, a boosting transformer or a step-down transformer does not need to be distinguished, and detection and recognition are achieved.

Description

technical field [0001] The invention belongs to the technical field of transformer detection, and relates to a device for identifying the same end and the different end of a primary and secondary coil of a transformer. Background technique [0002] Some transformers, coupling coils or oscillating coils need to identify the primary and secondary terminals of the same name or different terminals of these coils. Sometimes it is very troublesome to identify the terminals of the same name of multiple windings of the transformer during electronic production, maintenance and replacement of transformers. The special instrument used to detect the same-name end of the transformer coil winding is not available in the market, so it is necessary to design and manufacture a transformer primary and secondary coil same-name end and different-end identification device. The invention adopts an identification circuit composed of one-way thyristor and other components. . Use it to quickly iden...
