DEVICE FOR TESTING QUALITY OF CONNECTION OF ELECTRODES IN WORKING SOLDERED JOINT OF THERMO-ELECTRIC TRANSFORMER Russian patent published in 2006 - IPC G01K15/00 

FIELD: electric engineering.

SUBSTANCE: device has constant voltage source, commutator, timer, launching device and device for registration of transition processes of alternation of electrical characteristics of thermo-electric transformer. Controlling coils of commutator power relay and signaling relay of commutator are connected to timer via launching device. Contacts of power relay of commutator are mounted with possible alternating connection of clamps for connecting electrodes of thermo-electric transformer either to direct current source, or to device for registration of transition processes. Clamps of signaling relay of commutator are mounted with possible disconnection of device for registration of transition processes from clamps for connecting electrodes of thermo-electric transformer.

EFFECT: improved productiveness of control and increased trustworthiness of diagnostics of quality of connection of electrodes in working soldered joint.
