（考案の利用分野）
本考案は、負荷を停電させることなく、電力量
計の端子金具に接続された電源側配線と負荷側配
線とを短絡させ得る構造の電力量計に関するもの
である。[Detailed Description of the Invention] (Field of Application of the Invention) The present invention is an electric energy meter with a structure that can short-circuit the power supply side wiring connected to the terminal fitting of the electricity meter and the load side wiring without causing a power outage to the load. It is related to the meter.
（考案の背景）
電力量計は、一定年限が過ぎると、取り換える
よう規定されている。従来、電力量計を取り換え

る電源側配線及び負荷側配線を外して、作業して
いたので、その間、負荷が停電していた。(Background of the idea) It is stipulated that electricity meters must be replaced after a certain period of time. Conventionally, when replacing a watt-hour meter, the power supply side wiring and load-side wiring connected to the terminal fittings of the watthour meter were removed before work was performed, resulting in a power outage to the load during that time.
また、電力量計の取換えの間の停電を回避する

５の間を電線６により接続することが、従来行わ
れていた。しかし、この方法は、作業に手間がか
かることが問題であつた。 In addition, in order to avoid a power outage during the replacement of the watt-hour meter, as shown in FIG. Attach the short-circuit terminals 5 through the insulation, and connect between 1S and 1L of the terminal fitting 2 and between 2S and 2L.
Conventionally, the shorting terminals 5 were connected by an electric wire 6 so as to short-circuit between 3S and 3L. However, this method has a problem in that it is time-consuming.

で、計器本体交換の作業性が悪い。 Furthermore, in the past, the applicant divided the terminal block into a first terminal block on the meter body side and a second terminal block on the wiring side, and when replacing the meter body, the terminal fitting of the second terminal block was attached to a shorting bar. A terminal board for a watt-hour meter was developed in which the meter body could be replaced without causing a power outage by short-circuiting the second terminal block and removing the second terminal block from the first terminal block.
No. 61-28067. However, since the second terminal block is separated downward, if the wiring is thick and rigid, it is not easy to remove the second terminal block, and it is difficult to remove the second terminal block from the instrument body. At the time of replacement, the first terminal block, the second terminal block, and the meter body must all be removed and reattached, so the work efficiency of replacing the meter body is poor.
