Description

TECHNICAL FIELD The present invention relates to a transport jig used for transporting watt-hour meter parts and a method for transporting watt-hour meter parts.

A watt-hour meter is used to measure the amount of electricity used, which serves as a basis for calculating electricity charges, and the usable period is stipulated by a certification system based on the Measurement Law. Therefore, when the usable period of the watt-hour meter has passed, it is necessary to replace the watt-hour meter.

When replacing a conventional induction-type watt-hour meter that consists of a rotating disk, it is necessary to replace the entire watt-hour meter, including the terminal part that is connected to the electric wire, which places a heavy burden on the on-site worker. . Therefore, in recent years, in consideration of the workability and safety of replacement work, watt-hour meters have come to be seen that have a configuration in which the measuring unit that measures the amount of power and the terminal part (terminal block) are separated (patent Reference 1). In such a separable watt-hour meter, a terminal block and a measuring section for measuring electric energy are fixed, and a terminal block and a terminal cover are fixed. Moreover, in such a replaceable watt-hour meter, the measuring part and the terminal cover are engaged so that water droplets and dust do not enter the inside of the watt-hour meter. In the replacement work of such a separable watt-hour meter, the worker only needs to carry and replace the weighing unit, which reduces the burden on the worker.
