It's about.

Conventionally, when an electric meter is replaced due to the need for voltage boost or a defective electric meter, a power outage occurs on the consumer side during the replacement work, which not only disrupts electricity sales but also causes complaints on the electric power consumer side.

In order to solve the problem of power outage when replacing the electric meter, related technology is disclosed in Korean Patent Publication No. 10-2004-0098865 (2004.11.26) and Korean Patent Registration No. 10-0863593 (2008.10.08). .

However, the prior art of electronics consists of connecting the shorting pieces to each other, which can prevent power outages when replacing electric meters, but has the disadvantage of not only being difficult to install, but also allowing conduction (electricity theft), and the size of the shorting pieces. There is a problem that there is a limit to capacity change.

In addition, the latter prior art also has the advantage of being able to easily replace the electric meter without power outage with a fixed terminal block and uninterruptible bypass, but poor contact may occur by simply inserting the uninterruptible bypass into the seating groove, and it can be used for three-phase and single-phase use. It must be manufactured separately, and if some of the seating grooves are damaged, the entire unit must be replaced.

In order to solve the above-mentioned problems, Republic of Korea Patent Publication No. 10-1030727 provides that electric meter replacement work can be done without power outage. It can be used as a prefabricated three-phase four-wire system as well as a single-phase two-wire system, and can be replaced individually in case of damage. We also provide uninterruptible terminal blocks for electric meter replacement that can be repaired.

When replacing an electric meter, open the sealed protective cover (not shown) of the electric meter box, insert each connection terminal (66) of the bypass unit (50) (60) into the third terminal (45) of the movable terminal block (40), and then , the bypass portions 50 and 60 are fastened by tightening the tightening screws 46 into the screw holes 46a formed on one side of each third terminal 45.

As described above, the uninterruptible terminal block of the conventional Korean Patent Publication No. 10-1030727 has the inconvenience of having to fasten the bypass unit every time the electric meter is switched on.

In addition, the bypass conductor 68 constituting the bypass portion of the uninterruptible terminal block of the conventional Korean Patent Publication No. 10-1030727 has a parabolic structure erected upward and occupies a significant volume.
