Abstract

The invention relates to a corona test device for an OPPC (optical fiber composite phase conductor) connector box and a test method of the corona test device. The corona test device comprises the connector box, a test auxiliary prolonging OPPC optical cable, a test auxiliary prolonging ADSS (all-dielectric self-supporting) optical cable, a voltage source, an optical fiber attenuation monitor and an ultraviolet imager. High-voltage positive electrode of the voltage source is connected with an upper box body of the connector box through a voltage increasing line; a high-voltage negative electrode of the voltage source is grounded; one end of test auxiliary prolonging OPPC optical cable is connected with the upper box body of the connector box, one end of the test auxiliary prolonging OPPC optical cable is connected with a lower box body of the connector box, and the other end of the test auxiliary prolonging OPPC optical cable is connected with the optical fiber attenuation monitor through tail fiber; and the ultraviolet imager is used for observing generation and disappearance of corona on the connector box in corona test process under non-darkness condition in the daytime. The test device and the test method are used for laboratory simulation test for corona performance of the OPPC connector box in an OPPC operation line of 330 KV or more than 330 KV voltage level under assigned voltage.
