Abstract

The invention discloses a nuclear power plant cable mildew comprehensive treatment method. The method comprises the following steps that the mildew degree of cables is detected, and the to-be-treatedcables are determined according to the detection result; the to-be-treated cables are subjected to indentation modulus test, the usage parameters of the required dry ice cleaning equipment are calculated according to the obtained indentation modulus, the usage parameters comprise the ice feeding speed N, the dry ice spraying speed V and the dry ice spraying pressure P of the cleaning equipment, and after the equipment is set according to the obtained usage parameters of the dry ice cleaning equipment, dry ice is sprayed to the to-be-treated cables, and the to-be-treated cables are subjected tocleaning treatment. According to the nuclear power plant cable mildew comprehensive treatment method, the usage parameters of the proper dry ice cleaning equipment can be calculated and set, the usage amount of the required cleaning materials can be accurately set, the optimal cleaning effect and the minimum damage to the cable sheaths are guaranteed, time and labor are saved, and the method is convenient and efficient; the treatment method is a set of comprehensive moldy cable treatment system, and the safe and reliable operation of the cables of a nuclear power plant is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of cable mildew control systems, in particular to a method for comprehensive control of cable mildew in nuclear power plants. Background technique [0002] Cable is one of the most important electrical equipment in nuclear power plants. Its function is to transmit power, instrument signals and control signals. It is the neural network of the power plant. The reliability of cables directly affects the normal operation of nuclear power plants, and even affects nuclear safety. Most of my country's nuclear power plants are located on the eastern coast. During the rainy season, the air temperature and humidity are relatively high. Cables in this environment for a long time are prone to mold growth. At present, nuclear power plants have reported large-scale mold growth in cables. Some power plants This issue has been identified as a priority concern. [0003] Cable mold has the following hazards: After the mold on the surf...
