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.

Description

technical field [0001] The invention relates to the technical field of power system communication, in particular to a corona test device and a test method for an optical fiber composite overhead phase line joint box. Background technique [0002] Optical fiber composite overhead phase line is a new type of special power cable, which has the functions of wire and communication cable. It has been used exploratoryly in the transmission lines of 10kV, 35kV, 110kV and 220kV in the power field of our country, and it has begun The research and test section construction of 500kV voltage level OPPC and joint box was carried out. [0003] The optical fiber composite overhead phase joint box is an indispensable device in the application of OPPC line engineering, and its corresponding performance testing technology is a new technology. The corona test method for the optical fiber composite overhead phase wire splice box proposed this time is used for corona test of the optical fiber co...
