DETECTING DEVICE FOR CONTINUOUS WIRE INSULATION TESTING Russian patent published in 2017 - IPC G01R31/14 

FIELD: electricity.

SUBSTANCE: detecting device for continuous wire insulation testing is made in the form of two roll pins, made of the stainless steel, that have the U-shaped groove along the generating line. The roll pins are housed within the case, which is designed as a channel bar, among the parallel walls of which there is a non-conducting base for the detector element components arrangement, which is also designed as a channel bar. The parallel walls of the noted base are fixedly attached by fastening parts to the detector element case parallel walls, and the bottom of the noted base is placed transversely to the detector element case base. Two metal balancing levers, two springs, two sliding contacts, two outputs for the power supply attachment, two guide bushes, a disk with equally accomplished open-ended radial-type slotted holes, where one plane of the disk is designed as a cylindrical barrel, the ultra-violet light-emitting diode and the ultra-violet optical diode are complementarily added in the detector element. The balancing levers are designed as metal plates, the cylindrical bearing axles are rigidly fixed at one end of every plate perpendicular to the plate flat surface, at the other end of every balancing levers plate there are axial bores perpendicular to the balancing levers flat surface. These bores are mounted rigidly to the non-conducting basis for the detecting device component arrangement, the pivoting roll pins that are pressed toward one another with the help of the surface generator by virtue of the springs at the contact point, which lies on the normal reference axis of the noted roll pins. The barrel of the mentioned disk with radial-type slotted holes is coaxially attached to the side face of one of the roll pins. The grooves are accomplished along the roll pins surface generator. They lie opposite to each other in roll pins contact and are designed to fix and restrict the wire motion in cross direction.

EFFECT: providing greater universality at the expense of the functional capacity enhancement, greater resolution capability, informativity and control precision.
