閉器アダプタに関するものである。[Detailed description of the invention] (Field of application of the invention) The invention provides a method for connecting a power supply and demand meter with a transformer, such as a watt-hour meter with a transformer or a composite meter for power supply and demand with a transformer, and a test switch. This relates to a test switch adapter that can be installed.
（考案の背景）
現在、変成器付電力需給用計器には、試験用開
閉器が接続されている。試験用開閉器は、実負荷

ので、実負荷試験時の配線を第５図に、虚負荷試
験時の配線を第６図に、それぞれ示す。(Background of the invention) Currently, a test switch is connected to a power supply and demand meter with a transformer. The test switch is used when conducting actual load tests, imaginary load tests, etc. The wiring for the actual load test is shown in FIG. 5, and the wiring for the imaginary load test is shown in FIG. 6, respectively.

と標準器４で同時に軽量されるようにする。 During the actual load test, by inserting the actual load test connector (not shown) into the test switch 1, the connection of the test switch 1 is switched as shown in Figure 5, and the instrument transformer is connected. The secondary voltage of the current transformer 2 is applied to both the meter under test 3 and the standard 4, and the secondary current of the current transformer 5 is applied in series to the meter under test 3 and the standard 4 to determine the actual power used by the load. The quantity is the meter under test 3
and standard device 4 so that the weight can be reduced at the same time.
虚負荷試験時には、試験用開閉器１に虚負荷試

準器４で同時に計量される。 During the imaginary load test, by inserting the imaginary load test connector (not shown) into the test switch 1, the connection of the test switch 1 is switched as shown in Figure 6, and the instrument transformer is connected. The secondary sides of the transformer 2 and the current transformer 5 are connected to an alternative meter 6, and the meter under test 3 is connected to an imaginary load generator 7. As a result, the amount of electric power generated by the imaginary load generator 7 is measured simultaneously by the meter under test 3 and the standard meter 4.
試験用開閉器１は、コネクタが接続されない状
態で、対応する計器側端子金具と電源負荷側端子
金具の間（例えば１Ｓ−１Ｓ間）が接続される。 In the test switch 1, the connector is not connected, and the corresponding meter-side terminal fitting and power load-side terminal fitting (for example, between 1S and 1S) are connected.

となく、安全に計器を交換することができる。 In addition, when replacing a meter while it is installed at a customer, a short-circuit connector (not shown) is inserted into the test switch 1, so that the corresponding meter side terminal fitting and power load can be replaced. The side terminal fittings are briefly disconnected, and the power load terminal fittings P 1 , P 2 , P 3 connected to the secondary side of the voltage transformer 2 are opened.
The power supply load side terminal fittings 1S-1L and 3S-3L connected to the secondary side of the current transformer 5 are short-circuited. Thereby, the meter can be replaced safely without opening the secondary side of the current transformer 5.

い。By the way, in general, the terminal pitch of a power supply and demand meter and the terminal pitch of a test switch are different in structure and number of terminals, and therefore are not the same. In particular, in the case of electronic watt-hour meters and electronic power supply/demand composite meters, pulse service terminals and check terminals are provided in addition to the power supply load terminals, so the terminal pitch is the same as that of the test switch. It is very different. Therefore, in the past, the connection between the terminal of the power supply and demand meter and the terminal of the test switch was made using flexible vinyl wires, and wiring connections had to be made one by one, making the wiring work difficult. is not easy.
