Abstract：
 The stress sensor head consists of a casing, a glass sensor head and current conductor. The current conductor is placed inside an aluminum alloy cylinder with an insulating layer in between, the aluminum alloy cylinder is placed inside the hole in the center of the glass sensor head with heat insulating material in between, the glass sensor head is placed inside a sealed casing with transition medium in between, and the transition medium is positioned on the casing via an aluminium alloy plate and a buffering layer. The present invention can reduce the effect of temperature and double refraction to the lumpy magneto-optical glass current transformer so as to raise the accuracy and stability of the magneto-optical current transformer.
