이때 전류측정 어댑터(30)는 일면에 전압측정단자(10)의 두 개의 R단자, 두 개의 S단자, 두 개의 T단자에 삽입될 수 있는 6개의 단자 31a ~ 31f가 있다. 여기서 31a 단자는 첫 번째 R단자에, 31b는 첫 번째 S단자에, 31c는 두 번째 R단자에, 31d는 첫 번째 T단자에, 31e는 두 번째 T단자에, 31f는 두 번째 S단자에 삽입된다. 그리고 단자 31a와 31c, 단자 31b와 31f, 단자 31d와 31e가 서로 전기적으로 연결된다.At this time, the current measurement adapter 30 has six terminals 31a to 31f that can be inserted into two R terminals, two S terminals, and two T terminals of the voltage measurement terminal 10 on one side. Here, terminal 31a is inserted into the first R terminal, 31b is inserted into the first S terminal, 31c is inserted into the second R terminal, 31d is inserted into the first T terminal, 31e is inserted into the second T terminal, and 31f is inserted into the second S terminal. do. Also, terminals 31a and 31c, terminals 31b and 31f, and terminals 31d and 31e are electrically connected to each other.

따라서 전류측정 어댑터(30)가 전압-전류 측정기(1)에 장착되면 두 개의 R단자는 전기적으로 서로 연결되고, 두 개의 S단자 및 두 개의 T단자도 각각 서로 전기적으로 연결된다.Therefore, when the current measurement adapter 30 is mounted on the voltage-current meter 1, the two R terminals are electrically connected to each other, and the two S terminals and the two T terminals are also electrically connected to each other.

한편 전류측정 어댑터(30)의 타면에는 3개의 단자(32a, 32b, 32c)만 형성된다. 여기서 제1단자(32a)는 31a 단자에 전기적으로 연결되고, 제2단자(32b)는 31b단자에 전기적으로 연결되며, 제3단자(32c)는 31d단자에 전기적으로 연결된다. 즉 타면에 형성된 3개의 단자(32a, 32b, 32c)는 R단자, S단자, T단자가 된다.Meanwhile, only three terminals 32a, 32b, and 32c are formed on the other side of the current measuring adapter 30. Here, the first terminal 32a is electrically connected to the terminal 31a, the second terminal 32b is electrically connected to the terminal 31b, and the third terminal 32c is electrically connected to the terminal 31d. That is, the three terminals 32a, 32b, and 32c formed on the other surface become the R terminal, the S terminal, and the T terminal.

Then, the two R terminals, the two S terminals, and the two T terminals are electrically connected to each other, so the user does not need to wire these terminals together. In addition, the adapter 30 has three terminals 32a, 32b, and 32c serving as an R terminal, an S terminal, and a T terminal. Therefore, the operator can measure the current by connecting the first terminal 32a to the R line, the second terminal 32b to the S line, and the third terminal 32c to the T line. Therefore, according to the present embodiment, the operator does not need to separately wire the terminals of the voltage-current meter 1, and connects the terminals 32a, 32b, and 32c formed on the adapter 30 to the R wire by mounting the adapter 30 of the present embodiment. , S line, T line can be connected to measure the current. Thus, errors due to wiring errors can be prevented as in the prior art.

And 41a and 41c, 41b and 41f, and 41d and 41e are electrically connected to each other. And 42a is coupled to the Ri terminal, 42b to the Si terminal, 42c to the Ti terminal, 42d to the Ro terminal, 42e to the So terminal, and 42f to the To terminal. Also, 41a and 42d, 41b and 42e, and 41d and 42f are electrically connected to each other.

따라서 전류측정 어댑터(40)가 전압-전류 측정기(1)에 장착되면 두 개의 R단자는 전기적으로 서로 연결되고, 두 개의 S단자 및 두 개의 T단자가 각각 서로 전기적으로 연결된다. 그리고 R단자와 Ro단자, S단자와 So단자, T단자와 To단자도 가각각 서로 전기적으로 연결된다.Therefore, when the current measurement adapter 40 is mounted on the voltage-current meter 1, the two R terminals are electrically connected to each other, and the two S terminals and the two T terminals are electrically connected to each other, respectively. And the R terminal and Ro terminal, S terminal and So terminal, T terminal and To terminal are also electrically connected to each other.

한편 전류측정 어댑터(40)의 타면에는 6개의 단자(43a ~43f)만 형성된다. 여기서 제1단자(43a)는 42a 단자에, 제2단자(43b)는 42b단자에, 제3단자(43c)는 43c단자에, 제4단자(43d)는 42d단자에, 제5단자(43e)는 42e단자에, 제6단자(43f)는 42f단자에 전기적으로 연결된다. 즉 타면에 형성된 6개의 단자(43a ~ 43f)는 Ri단자, Si단자, Ti단자, Ro단자, So단자, To단자가 된다.Meanwhile, only six terminals 43a to 43f are formed on the other side of the current measuring adapter 40 .

That is, the six terminals 43a to 43f formed on the other surface become the Ri terminal, the Si terminal, the Ti terminal, the Ro terminal, the So terminal, and the To terminal.

따라서 본 실시예를 사용하여 직접측정 방식으로 전류를 측정하기 위해서 본 실시예의 전류측정 어댑터(40)를 전압-전류 측정기(1)의 전압측정단자(10) 및 전류측정단자(20)에 장착한다. 그러면 두 개의 R단자, 두 개의 S단자, 두 개의 T단자는 전기적으로 서로 연결되고, R단자와 Ro단자, S단자와 So단자, T단자와 To단자가 전기적으로 서로 연결되어 사용자는 이들 단자를 서로 결선할 필요가 없다.Therefore, in order to measure current by direct measurement method using this embodiment, the current measuring adapter 40 of this embodiment is mounted on the voltage measuring terminal 10 and the current measuring terminal 20 of the voltage-current measuring device 1. . Then, the two R terminals, the two S terminals, and the two T terminals are electrically connected to each other, and the R terminal and the Ro terminal, the S terminal and the So terminal, and the T terminal and the To terminal are electrically connected to each other. There is no need to wire each other.

그리고 어댑터(40)에는 Ri단자, Si단자, Ti단자, Ro단자, So단자, To단자 역할을 하는 6개의 단자(43a ~ 43f)이 형성되어 있다. 그래서 작업자는 제4단자(43d)를 R선에, 제5단자(43e)를 S선에, 제6단자(43f)를 T선에 연결하면 전류를 측정할 수 있다. 따라서 본 실시예에 의하면 작업자는 전압-전류 측정기(1)의 단자를 별도로 결선할 필요 없이 본 실시예의 어댑터(40)를 장착하여 어댑터(40)에 형성된 단자(43d ~ 43f)를 R선, S선, T선에 연결하면 전류를 측정할 수 있다. 그래서 종래와 같이 결선 오류로 인한 잘못을 방지할 수 있다. In addition, the adapter 40 has six terminals 43a to 43f serving as a Ri terminal, Si terminal, Ti terminal, Ro terminal, So terminal, and To terminal. Therefore, the operator can measure the current by connecting the fourth terminal 43d to the R line, the fifth terminal 43e to the S line, and the sixth terminal 43f to the T line. Therefore, according to the present embodiment, the operator does not need to separately wire the terminals of the voltage-current meter 1, and attaches the adapter 40 of this embodiment to connect the terminals 43d to 43f formed on the adapter 40 to the R line, S You can measure the current by connecting to the line or T line. Thus, errors due to wiring errors can be prevented as in the prior art.
