Abstract

An offshore substation wall bushing aging assessment method considering high and low temperature factors is characterized in that firstly, an offshore substation wall bushing aging assessment platform considering high and low temperature factors is built, and the assessment steps are as follows: a wall bushing test object is placed in a test box to complete grounding; the working condition of the wall bushing is simulated through the working voltage simulator, the temperature in the test box is continuously changed by arranging the temperature adjusting switch, the magnitude of current flowing through the wall bushing under different temperature conditions is captured through the current measuring device, and the corresponding temperature and current data are transmitted to the host. And then calculating an aging evaluation reference value of the wall bushing under the corresponding condition, and further judging what degree the aging of the wall bushing reaches and whether the wall bushing needs to be replaced according to the aging evaluation reference value of the wall bushing. The method mainly aims at evaluating the aging of the wall bushing of the offshore transformer substation, and the main implementation method is to consider the aging evaluation reference value of the wall bushing of the offshore transformer substation, so that the method has non-negligible significance for safe and stable operation of the offshore transformer substation.

Description

technical field [0001] The invention belongs to the technical field of marine casing protection, in particular to an aging evaluation method for an offshore substation through-wall casing that takes into account high and low temperature factors. Background technique [0002] Offshore oilfields are usually in the form of isolated islands, which are far from the land, which is determined by the distribution law of submarine oil and gas resources. Therefore, the safe and stable operation of equipment in the process of offshore oilfield development is a crucial part. In the offshore oil drilling platform, the offshore wall bushing is one of the key devices, especially the air tightness of the wall bushing must be guaranteed. The performance of the through-wall casing is directly related to the operation safety of the entire oil drilling platform, especially in the inconvenient offshore environment, which may not be able to get timely assistance in the event of an emergency. The...
