본 고안은 계기용 변성기에 사용되는 단자대에 관한 것으로서, 더욱 상세하게는 계기용 변성기에 장착시 결선이 용이하도록 하는 계기용 변성기의 2차 단자대에 관한 것이다.The present invention relates to a terminal block used in the instrument transformer, and more particularly, to a secondary terminal block of the instrument transformer for easy connection when mounted on the instrument transformer.

일반적으로 계기용 변성기는 고전압·대전류의 계측 등에서 계기와 전기회로 사이에 삽입하여 계측하기 쉽게 하기 위한 장치를 말한다. 이러한 계기용 변성기에는 각 단자별로 결선을 용이하게 하는 2차 단자대가 구비된다.In general, a transformer for an instrument is a device for easy measurement by inserting it between an instrument and an electric circuit in measurement of high voltage and large current. Such instrument transformers are provided with secondary terminal blocks that facilitate wiring for each terminal.

종래의 계기용 변성기에 사용되는 2차 단자대는 프레임(31)에 소켓(41)이 삽입되는 다수의 소켓 삽입구가 형성되고, 소켓 삽입구의 하부에 프레임(31)을 관통하는 결선공(33)을 형성시킨다.The secondary terminal block used in the conventional instrument transformer is formed with a plurality of socket insertion holes into which the socket 41 is inserted into the frame 31, and a connection hole 33 penetrating the frame 31 in the lower portion of the socket insertion hole. To form.

프레임(31)에 삽입되는 소켓(41)은 전기전도도가 우수한 금속재질로 이루어지며, 하부면에는 축방향으로 전선(45)이 삽입되는 결선공(33)이 형성되고, 측면에는 결선공(33)에 삽입된 전선(45)을 고정시키는 결선볼트(43)가 삽입되는 구멍이 형성된다.The socket 41 inserted into the frame 31 is made of a metal material having excellent electrical conductivity. A connection hole 33 into which an electric wire 45 is inserted in the axial direction is formed at a lower surface thereof, and a connection hole 33 is formed at a side surface thereof. A hole into which the connection bolt 43 for fixing the wire 45 inserted into the hole is inserted is formed.

소켓(41)을 프레임(31)의 소켓 삽입구에 삽입시킨 후, 소켓(41)의 결선공(33)과 프레임(31)의 결선공(33)을 일치시키고, 상기 결선공(33)에 피복이 제거된 전선(45)을 삽입시킨 후, 결선볼트(43)를 이용하여 고정시킨다.After inserting the socket 41 into the socket insertion hole of the frame 31, the connection hole 33 of the socket 41 and the connection hole 33 of the frame 31 coincide, and are covered with the connection hole 33. After inserting the removed electric wire 45, it is fixed using the connection bolt 43.

여기서, 프레임(31)에 삽입되는 소켓(41) 수는 통상적으로 3상 4선 방식에 적용할 수 있도록 11개의 소켓(41)이 삽입된다. 3개(1S, 2S, 3S)는 계기용 변류기에 연결되고, 4개(P1, P2, P3, P0)는 계기용 변압기에 연결되며, 3개(1L, 2L, 3L)는 접지를 위해 각 상에 연결되고, 나머지 하나는 접지된다.Here, the number of sockets 41 inserted into the frame 31 is typically 11 sockets 41 are inserted to be applied to the three-phase four-wire system. Three (1S, 2S, 3S) are connected to the instrument current transformer, four (P1, P2, P3, P0) are connected to the instrument transformer, and three (1L, 2L, 3L) are each connected to ground Connected to the phase, and the other is grounded.

그러나, 상기와 같은 종래의 계기용 변성기의 2차 단자대(30)는 계기용 변성기(10)에 2차 단자대(30)를 고정시키고, 결선시킬 때 결선이 제대로 되지 않는 경우가 종종 발생하는 문제가 있었다. 2차 단자대(30)를 계기용 변성기의 단자대함(12)에 체결한 후, 작업자가 일일이 전선의 피복을 벗기고 단자대의 하부면에 형성된 결선공(33)을 통과시켜 소켓(41)의 하부면에 형성된 결선공(33)에 삽입하고 결선볼트(43)를 이용하여 고정시킨다.However, when the secondary terminal block 30 of the conventional instrument transformer as described above is fixed to the secondary terminal block 30 to the instrument transformer 10, the connection often does not occur properly when the connection is made. there was. After fastening the secondary terminal block 30 to the terminal box box 12 of the instrument transformer, the operator uncovers the electric wire and passes through the connection hole 33 formed on the lower surface of the terminal block to lower the surface of the socket 41. Inserted in the connection hole 33 formed in and fixed using a connection bolt 43.

이때, 도3에서 보는 바와 같이 일측에 위치하여 접지 단자에 연결되는 단자(P0, 1L ,2L, 3L)들은 두 가닥이 전선(45)이 결선공(33)에 삽입되어 인접한 단자를 연결해주어야 하는데, 종종 일부 전선(45)이 구부러지거나 하여 결선공(33)에 삽입되지 않는 현상이 발생한다.At this time, as shown in Figure 3, the terminals (P0, 1L, 2L, 3L) located on one side and connected to the ground terminal should have two strands of wires 45 inserted into the connection holes 33 to connect adjacent terminals. In some cases, a phenomenon in which some wires 45 are bent or inserted into the connection hole 33 occurs.

상기와 같은 오결선으로 인하여 전원이 인가되어 사용될 때, 제품이 소손되거나, 측정을 할 수 없는 문제점이 있었다.Due to the incorrect wiring as described above, when power is applied and used, there is a problem in that the product is damaged or cannot be measured.
