Description

  The present invention relates to a watt-hour meter connection that connects a watt-hour meter having a plurality of cylindrical external lower terminals provided on a lower surface and a side external terminal provided on a side surface and a power source side of a test apparatus. In particular, the present invention relates to a watt-hour wire connection device that can be easily connected even if the positions of the external terminals of each watt-hour meter are different when performing performance tests of various types of large current watt-hour meters.

  2. Description of the Related Art Conventionally, a performance test (certification test) for inspecting whether a watt-hour meter satisfies a predetermined standard has been performed using a test apparatus. When performing such a performance test, it is necessary to connect the connecting conductor on the power source side of the test apparatus and each external terminal of the watt hour meter. However, in particular, a watt-hour meter with a rated current of 120 A (hereinafter also referred to as a large-current watt-hour meter) has problems such as different dimensions between external terminals of the watt-hour meter for each manufacturer and model, and heat generation. As a result, it is difficult to automatically perform the wiring work. For this reason, the connection work between the test apparatus and the large current watt-hour meter is often performed manually using a driver or the like.

  Moreover, what was described, for example in patent document 1 is known as an automatic connection device for large current watt-hour meters which automatically performs a connection work between a test apparatus and a large current watt-hour meter. This automatic connector has a current terminal that is slidably attached to the connector cradle. In the performance test, the current terminal is slid to the left and right according to the type of each watt hour meter, and is then inserted into the cylindrical terminal of the watt hour meter so as to contact the inner wall of the cylindrical terminal.

  However, in the automatic connector described in Patent Document 1, each current terminal can be slid in the left-right direction, but it is difficult to adjust the position of each current terminal in the up-down direction. That is, the structure of the lower external terminal of the watt hour meter is slightly different for each manufacturer and model. For example, the height position of the screw in the cylindrical terminal is also slightly different, so the current terminal of the wire connector inserted in the lower external terminal Is preferably adjustable in the vertical direction.

Further, in the automatic connector described in Patent Document 1, there is no voltage terminal that can automatically contact the lateral external terminal of the watt hour meter.
