Abstract

The invention relates to a pollution-considering offshore substation wall bushing life evaluation method, which is characterized in that a pollution-factor-considering offshore substation wall bushing life evaluation platform is established, and the evaluation steps are as follows: a host sends a pollution concentration setting signal to a pollution concentration control device; a pollution spraying generation device in the test box sprays pollution into the test box, so that the pollution concentration in the test box is adjusted, a pollution concentration tester measures the pollution concentration in the test box every t0 seconds and transmits a result to a data collection module, the data collection module transmits data to a host, a power frequency power supply is turned on, and the host is started. The current parameter tester measures the operation current value of the dirty bushing sample under the power frequency voltage, collects the current parameter through the data collection module, transmits the current parameter to the host, calculates the life evaluation factor of the wall bushing, and then evaluates the life evaluation factor of the wall bushing so as to judge whether the wall bushing needs to be replaced. The method mainly aims at evaluating the service life of the offshore wall bushing, the main implementation method is to consider the service life evaluation factor of the wall bushing, and the method is of great significance to stable operation of an offshore oil drilling platform.

Description

technical field [0001] The invention belongs to the technical field of marine casing protection, in particular to a method for evaluating the service life of an offshore substation through-wall casing in consideration of pollution. Background technique [0002] As a big marine country, my country is rich in marine resources. Marine energy is closely related to the future development of our country and will directly affect the stability of our country. Moreover, my country is striving to become an ocean power. As the main equipment for offshore oil and gas development, offshore oil drilling platforms are directly related to the stability of my country's offshore oil and gas production. The offshore wall-penetrating casing is an important part of the offshore oil drilling platform, so its performance requirements are relatively strict, and it must have good insulation performance and sufficient mechanical strength to ensure the air tightness of the casing. The entire offshore...
