Temperature cycling test device for OPPC (optical fiber composite phase conductor) connector box and test method

Abstract

The invention provides a temperature cycling test device for an OPPC (optical fiber composite phase conductor) connector box and a test method. The test method is used for studying the performance change of the OPPC connector box at an extremely low temperature and an extremely high temperature so as to ensure safety and stability in operation of the practical engineering. The test device comprises an auxiliary extension optical cable, a high / low-temperature test box and an optical fiber attenuation tester (or optical time-domain reflectometer); and the test method comprises the steps of: splicing and coiling optical fiber in the connector box body, sealing the connector box body, splicing test auxiliary extension OPPC optical cable, configuring the optical fiber attenuation tester, performing an attenuation test method and the like. In the invention, the high / low-temperature test box simulates the dynamically changing external environment for the OPPC connector box so that the temperature range of the high / low-temperature cycling test is flexible and controllable and better conforms to the practical environment; and in the splicing of the test auxiliary extension OPPC optical cable, a long-enough optical fiber channel is provided for the optical fiber attenuation monitoring by connecting the optical fibers in series, thereby ensuring the reliability of the test result.

Description

technical field [0001] The invention belongs to the field of performance testing of a 500kV optical fiber composite phase line splice box, and specifically relates to a temperature cycle test device and a test method for an optical fiber composite phase line splice box. Background technique [0002] Optical Fiber Composite Phase Conductor (OPPC) is a new type of power special optical cable developed in recent years. It is erected as a common phase wire in the power transmission and transformation line, which can prevent the OPGW from being disconnected due to lightning strikes. Fatal problems such as strands and broken fibers can be avoided, and electrochemical corrosion of the ADSS outer sheath can be avoided at the same time. Optical fiber composite phase line has the functions of wire and communication optical cable, and has been used in power transmission lines with voltage levels of 10kV, 35kV, 110kV and 220kV in my country's power field. [0003] The wide application ...
