Claims

[Scope of utility model registration request]

In a high-voltage semiconductor rectifier in which a plurality of semiconductor rectifiers are connected in series within the same phase and an optical fiber is used as a means to display the voltage applied to the semiconductor rectifier, a plurality of indicator lights each having a different display color are used. 1. A semiconductor rectifier device, characterized in that an optical signal is transmitted through a single optical fiber, and a failure state and a failure location of a semiconductor rectifier element are determined based on a change in the display color of the optical fiber.
