To provide a contact load measuring apparatus that facilitates measuring the load and displacement of a contact of an oil tank without applying a load to portions other than the contact of the oil tank of an on-load tap changer.
The contact load measuring apparatus includes: a load meter 11 which receives a reaction force from a contact 8 to measure a load; an operation mechanism 12 which is connected to the load meter and moves the load meter in a horizontal direction; a displacement meter 13 which measures displacement of the load meter; and a support unit 14 which supports the load meter, the operation mechanism, and the displacement meter. The support unit includes: a pole brace 15 in which the load meter, the operation mechanism, and the displacement meter are attached to the lower part of the pole brace 15; and a support frame 16 extended from the upper part of the pole brace 15 in the horizontal direction to be installed. The pole brace is inserted into the oil tank from an upper opening 4 of the oil tank 1 and the support frame is placed on a flange 5, to hold the load meter at an attachment height of the contact. In this state, the load meter is moved in the horizontal direction by the operation mechanism, and is brought into contact with the contact to measure the load and displacement of the contact.
