SPACE CHARGE MEASURING DEVICE FOR POWER CABLE

摘要

The present invention relates to a space charge measuring device for a power cable, and more particularly, applying heat to a power cable such as an HVDC cross-linked polyethylene (XLPE) cable used in ultra-high voltage direct current transmission to a high temperature state under actual operating conditions, and driving accordingly It relates to a space charge measuring device for a power cable capable of measuring the space charge distribution by heat generated during operation. A space charge measuring device for a power cable according to the present invention is a space charge measuring device for a power cable for measuring a space charge accumulated inside an insulating layer of the power cable, comprising: a sample cable for measurement; an HVDC supply unit for applying an ultra-high voltage direct current to the core of the sample cable for measurement; a cable heating unit for heating the sample cable for measurement to a predetermined temperature; a space charge measuring unit for measuring the space charge of the sample cable for measurement heated to the predetermined temperature; characterized by including.
