Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of penetration pieces, and in particular to a device for realizing high-bandwidth data transmission of penetration pieces. Background Art
[0002] The early design of the reactor building penetrations did not have optical cable channels, and data communication could not be carried out through optical cables. The data transmission methods include connecting network cables to terminal blocks and connecting antenna feed lines to coaxial cables. The data bandwidth of these two methods is very limited. Under actual field measurements, the bandwidth is only 60 to 70 megabits. With the increasing demand for digitalization of power plants, the current traditional penetration data transmission method cannot meet the needs of high-bandwidth applications such as video surveillance and WiFi. If the original penetrations are modified to increase optical fiber link channels, the cost will be very high. On the one hand, the cost of penetrations is very expensive. On the other hand, the modification of penetrations involves risks such as unit shutdown losses, damage to the sealing of the penetrations leading to radiation dose leakage, and impact on other system services.
