This is to solve the hassle of selecting the appropriate relay so that it can be transformed and used immediately at the site.

종래의 계전기에 있어서는 전류센서인 변류기(이하 "변류기"라 약칭한다)가 일정 위치 즉 계전기의 앞면이나 측면에 수평으로 돌출되거나 또는 위쪽으로 수직상태로 돌출되거나 또는 계전기의 몸통에 관통되게 고정시킨 구조로 공급되고 있어서 사용하는 위치와 설계에 다라 계전기를 선택해야 하는 번거로움이 있다.In the conventional relay, a current transformer (hereinafter, referred to as a "current transformer"), which is a current sensor, is fixed at a predetermined position, that is, horizontally protruding from the front or side of the relay, vertically protruding upward, or penetrating through the trunk of the relay. As it is supplied with a circuit board, it is troublesome to select a relay according to the location and design to be used.

본 발명은 상기와 같은 번거로움과 불편을 해결코자 작업현장의 조건에 따라 즉석에서 변류기(CT)의 위치를 변경 사용할 수 있도록 하고자 제안하는 것이다.The present invention is to propose to be able to change the position of the current transformer (CT) on the fly according to the conditions of the workplace to solve the trouble and inconvenience as described above.

이를 위하여 본 발명에서는 변류기를 현장의 형편에 따라 수직으로 또는 수평으로 변경 사용할 수 있도록 하기 위하여 변류기를 계전기의 몸통 케이스에 삽탈(揷脫)과 고정이 자유로우며 상기 변류기는 90˚ 각을 변경시켜 고정이 가능하도록 구성함으로서 목적을 달성하도록 한 것이다.To this end, in the present invention, in order to be able to change and use the current transformer vertically or horizontally according to the circumstances of the site, the current transformer can be freely inserted and fixed in the trunk case of the relay, and the current transformer is fixed by changing the 90 ° angle. It is to be configured to achieve this purpose.

이하 본 발명을 첨부된 실시예의 도면에 따라 상술하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying embodiments.

도1은 본 발명을 설명키 위한 사시도로 계전기의 몸통케이스(1) 상측에는 명판(2)이 설치되고 여러 개의 외부와의 결선을 위한 터미널(3)이 배치되고 각종 신호등이 배치됨은 공지와 같은 것이며, 또한 몸통케이스(1)와 변류기(4)에 관통공(5)(5')이 천설(穿設)됨은 공지와 같은 것이므로 이에 대한 설명은 생략한다.1 is a perspective view for explaining the present invention, a name plate (2) is installed on the upper side of the trunk case (1) of the relay, the terminal (3) for the connection with a plurality of external arrangements and various signals are arranged as known In addition, the through-hole (5) (5 ') in the trunk case (1) and the current transformer (4) is a well-known (snow), so the description thereof will be omitted.

본 발명에서는 계전기의 전류센서인 변류기(4)(CT : Curent Transformer)를 계전기의 몸통케이스(1)에 삽탈과 고정이 가능하도록 되고, 나사(11, 11') 등에 의해 변류기(4)를 몸통케이스(1)에 고정하도록 되어 있다.In the present invention, the current transformer 4 (CT: Curent Transformer), which is a current sensor of the relay, can be inserted into and fixed to the trunk case 1 of the relay, and the current transformer 4 is connected to the main body by screws 11 and 11 '. It is fixed to the case 1.

또 도4에 도시와 같이 변류기(4)가 90˚ 각도로 변환시켜 고정할 수 있어서 변류기(4)로 하여금 수평 또는 수직으로 고정할 수 있음을 보여주고 있다.In addition, as shown in FIG. 4, the current transformer 4 can be fixed by converting it at an angle of 90 degrees, thereby showing that the current transformer 4 can be fixed horizontally or vertically.

즉 도4에서 (가)로 표시되는 변류기(4)는 수직으로 하여 몸통케이스(1)에 삽착 고정하는 상태이고, (나)로 표시되는 변류기(4)는 수평으로 몸통(1)에 고정할 수 있음을 표시하고 있다. 따라서 변류기를 각도에 따라 몸통케이스(1)속에 설치되는 PCB(6)와 전기적으로 접촉 연결하기 위해 도2(가)와 같이 변류기(4)에 콘넥터 베이스(8)(Connector base)가 설치하는 경우 PCB(6)는 배터리 콘넥터(7)(Battery Connector)를 통해 접촉시켜 연결하거나 도2(나)와 같이 변류기(4)에 소켓(10)을 설치하는 경우는 PCB(6)에 헤더(9)(Header)를 통해 전기적으로 연결하도록 할 수 있다.That is, the current transformer 4 indicated by (a) in FIG. 4 is vertically inserted into and fixed to the trunk case 1, and the current transformer 4 indicated by (b) is horizontally fixed to the trunk 1. It can be shown. Therefore, when the connector base (8) is installed in the current transformer (4) as shown in Fig. 2 (A) to electrically connect the current transformer to the PCB (6) installed in the body case (1) according to the angle The PCB 6 is connected by contacting through a battery connector 7 or the header 9 on the PCB 6 when the socket 10 is installed in the current transformer 4 as shown in FIG. It can be electrically connected through the (Header).

따라서 도3(가)와 같이 변류기(4)를 수평으로 몸통(1)에 고정하는 경우 상면에 설치되는 콘넥터 베이스(8)를 통해 또 수직으로 고정되는 경우는 변류기(4)의 단부(端部)에 위치하는 콘넥터 베이스(8)로 접촉 연결되며, 변류기(4)에 소켓(10)을 설치한 경우에는 소켓(10)을 도3(나)에 도시한 화살표 방향으로 회전시켜 헤더와 접촉 되도록 할 수가 있다. 도5(가)(나)는 계전기의 몸통케이스(1)에 변류기(4)를 수직 또는 수평으로 삽입하고 나사(11,11')등으로 변류기(4)를 계전기의 몸통케이스(1)에 고정함을 도시하고 있다.Accordingly, when the current transformer 4 is horizontally fixed to the body 1 as shown in FIG. 3 (a), when the current transformer 4 is fixed vertically through the connector base 8 installed on the upper surface, the end of the current transformer 4 Is connected to the connector base (8) located in the), and when the socket 10 is installed in the current transformer (4) to rotate the socket 10 in the direction of the arrow shown in Figure 3 (b) to be in contact with the header You can do it. Fig. 5 (a) (b) inserts the current transformer 4 vertically or horizontally into the trunk case 1 of the relay and inserts the current transformer 4 into the trunk case 1 of the relay with screws 11 and 11 '. The fixation is shown.

따라서 상기와 같은 구성으로 되는 본 발명 실시예에 의하면, 도4의 도시와 같이 몸통케이스(1)로부터 변류기(4)(가)(나)가 이탈된 상태에서 도5(가)에 도시와 같이 변류기(4)(가)를 수직상태로 삽착(揷着)하거나 도5(나)에 도시와 같이 변류기(4)(나)를 수평으로 삽착 할 수 있고 나사(11,11')에 의해 몸통(1)에 상기 변류기(4)를 임의 방향으로 고정 또는 삽탈할 수 가 있도록 되어 있으므로, 작업장의 형편에 따라 시공자는 전류센서인 변류기(4)를 계전기의 몸통케이스(1)에 임의로 수직 또는 수평으로 삽탈 고정을 할 수 있어서 작업상의 편리함으로 작업능률을 향상시킬 수가 있다.Therefore, according to the embodiment of the present invention having the configuration as described above, as shown in Figure 5 (a) in the state in which the current transformer 4 (a) (b) is separated from the body case 1 as shown in Figure 4 The current transformer 4 (A) can be inserted in a vertical position or the current transformer 4 (B) can be inserted horizontally as shown in Fig. 5 (B), and the body is screwed by screws 11 and 11 '. In (1), the current transformer 4 can be fixed or inserted in an arbitrary direction. Therefore, according to the circumstances of the workplace, the contractor can arbitrarily move the current transformer 4, which is a current sensor, to the trunk case 1 of the relay. Insertion and detachment can be fixed, which improves work efficiency due to the convenience of work.

상기와 같은 구성으로 되는 것이므로 배전반 공사시의 형편에 따라 변류기(4)의 위치를 도5의 (가)와 같은 수직으로 하여 사용코자하는 경우 도6의 (다)에 도시와 같이 몸통케이스(1)에 관통시킨 관통공(5)(5')을 통해 부하측 전원의 전류변화를 감지할 수 있도록 하고 또한 도5의 (나)와 같이 변류기(4)를 수평상태로 사용하는 경우 도6의 (가)와 같이 단상(單相)이거나 또는 (나)와 같은 3상(R.S.T)에 구애받음 없이 전원선을 몸통케이스 밖으로 또는 몸통을 통과시켜 전류의 변화를 감지할 수 있는 것이다.Since it is configured as described above, when the current transformer 4 is positioned vertically as shown in Fig. 5A according to circumstances at the time of construction of the switchboard, the trunk case 1 as shown in Fig. 6C. Through the through holes (5) (5 ') through which the current changes in the load-side power supply can be detected, and when the current transformer (4) is used in a horizontal state as shown in (b) of FIG. As in a), it is possible to sense the change of electric current by passing the power line out of the body case or through the body, regardless of single phase or three phase (RST).
