Bobbin eddy current test probe for condenser tubes in nuclear power plant

摘要

The present invention relates to a bobbin-type eddy current transducer used for the integrity evaluation of the condenser heat exchanger tube in a nuclear power plant turbine system. The present invention relates to a bobbin type eddy current probe for inspecting heat pipes of a power plant condenser.;To this end, the present invention enters into the heat transfer tube 501 of the condenser 500, and a probe front body having a coil and a head 2 to which the wire holder 1 is connected to check the integrity of the heat transfer tube 501 ( 4), a nuclear power plant multiplier comprising a rear body 5 connected to the front body 4 and a cable 6 and a holder wire 7 installed through the front and rear bodies 4 and 5; In the eddy current probe for inspecting heat pipes, a spring fixing sleeve (8) is formed at the rear end of the front body (4), and the spring fixing sleeve (8) is shot on the cable (6) at the rear end of the rear body (5). The structure is connected in contact with the spring stopper 10 for holding the mounted cable spring (9).
