Abstract

PURPOSE: To realize a miniature and lightweight transformer while maintaining the insulating performance by optical fiber extending over a long period, by hermetically holding the optical fiber.
CONSTITUTION: As the method of insulating and supporting a detection part, porcelain tube 14 capable of penetrating optical fiber 17 is used and insulating tube 18 communicating with the porcelain tube 14 and its through-hole is provided penetrating to lay optical fiber 17 up to the low voltage side, so that optical fiber 17 will hermetically held by porcelain tube 14, bellows 16A and 16B and insulating tube 18. In consequence, optical fiber 17 never gets contaminated due to external dust etc. Consequently, the insulating performance can be prevented from deteriorating.
