DEVICE FOR TEMPERATURE MEASUREMENT ON SURFACE UNDER ELECTRIC TENSION

摘要

FIELD: measuring equipment. ^ SUBSTANCE: device includes metal case in form of square substrate (plate) with ledges along the perimetre and porcelain cap of the same form, and mica plates laid between them. Thermistor is positioned between the plates, its outputs connected to detection device. The whole construction is screwed together to compress mica plates tightly. Distance from thermistor to metal case (substrate) and tightening screws maintains dielectric strength, while good thermal contact to bus surface is performed by compression of case to bus by a nut screwed to stud fixed to the case and passing through an orifice drilled in the bus. ^ EFFECT: temperature measurement on surface under electric tension. ^ 2 dwg
