Apparatus for sampling gas of XLPE underground power transmission cable insulation joint box and analysis method of gas used in the apparatus

摘要

The present invention relates to an XLPE underground transmission cable termination connection gas collecting apparatus, which is coupled to an installation hole (11) formed in a lower copper pipe (10) of a terminal connection box, Fixing means 41 and 51 for fixing the connection body 21 coupled to the connection body 21 and coupled to the lower copper tube 10, And a coupler member (61) coupled to an end of the connection body (21) to mediate connection between the connection body (21) and the gas sampling pump and to maintain the gas tightness. The present invention is advantageous in that it is possible to regularly collect the gas inside the lower copper pipe without performing the operation of disconnecting the line break and the lower copper pipe by installing a gas sampling device for XLPE underground transmission cable termination in the lower copper pipe.
