Description

오결선 방지용 단자대 {Terminal Apparatus for protecing wrong wire connection}Terminal block for incorrect wiring {Terminal Apparatus for protecing wrong wire connection}

본 고안은 단자대에 관한 것으로, 보다 상세하게는 공동으로 결선되는 단자에 대한 오결선 작업이 이루어지는 것을 방지하도록 한 오결 방지용 단자대에 관한 것이다.The present invention relates to a terminal block, and more particularly, to a terminal block for erroneous prevention to prevent the erroneous wiring work for the terminal to be jointly connected.

단자대는 주로 22,900 KV-Y로 공급받는 고객의 수전설비에 계기용 변성기와 계량기 사이에 설치하여 계기의 무정전 교환 또는 계기용 변성기의 고장을 주로 감시하는 기능을 수행하게 된다.The terminal block is installed between the transformer and the meter in the customer's faucet facility, which is usually supplied with 22,900 KV-Y, to monitor the uninterrupted exchange of the instrument or the failure of the transformer.

일반적으로 고압수용가의 전력 사용량을 계량하기 위한 고압 수전설비 계량 장치는 전원측에 해당되는 계기용 변성기와 단자대와 계량기 등으로 구성되어 있다.In general, the high-voltage power receiving facility metering device for measuring the power consumption of the high-voltage consumer is composed of a transformer, a terminal block and a meter for the power supply.

이러한 단자대는 전원측 계기용 변성기에서 단자대의 입력측에 연결되는 단자가 P1,1S,1L,P2,2S,2L,P3,3S,3L,P0의 순서로 배치되어 있다. These terminal blocks are arranged in the order of P1, 1S, 1L, P2, 2S, 2L, P3, 3S, 3L, and P0 connected to the input side of the terminal block in the transformer for the power supply instrument.

그런데 종래에는 단자대의 입력측 단자 중에서 1L,2L,3L,P0 단자는 단자대의 내부에서 다시 공동으로 연결되어 있어 별도의 전선을 이용하여 외부에서 재차 공 동으로 연결할 필요가 없게 된다. However, in the related art, 1L, 2L, 3L, and P0 terminals among the input terminals of the terminal block are jointly connected again inside the terminal block, so that there is no need to connect again from the outside using a separate wire.

그러나 전원측과 연결되는 단자대의 입력측 단자중에서 1S,2S,3S 단자와 연결하는 경우에 숙련된 작업자가 아니거나, 숙련된 작업자라 하더라도 외부에 단자 표시가 되어 있지 않은 경우에는 이들 단자의 좌우측에 인접된 1L,2L,3L 단자와 연결되는 오결선 상태가 발생되는 문제가 있다. 이처럼 입력측 단자가 오결선된 상태에서는 단자대에서 계량기측으로 사용량이 계량되지 않는 현상이 발생되어 비용 손실이 발생된다.However, in case of connecting to 1S, 2S, 3S terminal among the input terminal of the terminal block connected to the power supply side, even if the skilled worker is not equipped with terminal marking on the outside, adjacent to the left and right sides of these terminals There is a problem in that an incorrect wiring condition is connected to the 1L, 2L, and 3L terminals. As such, when the input terminal is incorrectly connected, the amount of usage is not measured from the terminal block to the meter side, resulting in a cost loss.

또한, 이러한 오결선 작업을 사후에 파악하게 되면, 이를 시정하기 위하여 부득이하게 사용중인 고객의 전기를 정전시킨 후에 결선 상태를 조정하게 되므로 고객에게 일시적으로나마 불편함을 주는 것은 물론이고, 장기적으로는 회사와 제품에 대한 이미지와 신뢰도를 저하시키는 문제가 있다.In addition, if this miswiring work is identified after the fact, in order to correct this, the power failure of the customer is inevitable and the wiring is adjusted. There is a problem that reduces the image and reliability of the product.

본 고안의 목적은 단자대의 오결선 작업을 방지할 수 있어 비용손실을 방지하도록 한 단자대를 제공함에 있다.An object of the present invention is to provide a terminal block to prevent the cost loss by preventing the wiring of the terminal block.

본 고안의 다른 목적은 단자대의 오결선 작업으로 인한 불량 발생을 방지하여 고객의 불편함을 주는 서비스의 저하를 예방함과 아울러 고객의 신뢰도를 향상시키도록 한 단자대를 제공함에 있다.Another object of the present invention is to provide a terminal block to prevent the deterioration of the service to give a customer inconvenience by preventing the occurrence of defects due to the wrong wiring work of the terminal block and to improve the reliability of the customer.
