FIBRE-OPTICAL SENSOR OF SPIRAL STRUCTURE

摘要

FIELD: measuring equipment.SUBSTANCE: invention belongs to fibre-optical sensors and can be used for check and measurement of parameters of voltage. The fibre-optical sensor of spiral structure is the multi-turn spiral element created by a spring wire. The set of a teeth of deformation is continuously distributed on the top surface and the bottom surface of a spring wire in the longitudinal direction along a spring wire; in two adjacent turns of the spring wire the deformation teeth on the bottom surface of the top turn of the spring wire and deformation teeth on the top surface of the bottom turn of the spring wire are arranged in staggered order to each other. An alarm optical fibre is clamped between deformation teeth on the bottom surface of the top wire of the spring wire and deformation teeth on the top surface of the bottom turn of the spring wire and is connected to the test facility by the optical fibre of transfer.EFFECT: increase of accuracy of measurement.10 cl, 10 dwg
