Description

스위치 장치의 동작능력을 제어하기 위한 회로 배치Circuit arrangement for controlling the operating capability of the switch device

첨부도면은 본 발명에 따른 회로배치의 한예를 나타낸 작용 설명도이다.The accompanying drawings are functional explanatory diagrams showing an example of the circuit arrangement according to the present invention.

본 발명은 하나의 변압기를 갖는 스위치장치의 동작능력을 제어하기 위한 회로 배치에 관한 것이다.The present invention relates to a circuit arrangement for controlling the operating capability of a switch device having a single transformer.

이러한 목적을 위한 DT-OS 23 16 099호에 의한 것과 같은 공지의 스위치장치는 개폐작용시 마다 발생되는 아아크(arc)로 인해 닳아져서 수명이 단축된다.Known switch devices, such as those according to DT-OS 23 16 099 for this purpose, are worn down due to arcs generated at every opening and closing action, resulting in a shortened life.

이러한 손상은 스위치 장치의 적절한 제어방법이 없었기 때문에 적절한 대책을 세우지 못함으로 인한 것이었다.This damage was due to the lack of proper countermeasures due to the lack of proper control of the switchgear.

본 발명은 이러한 문제점을 해결하기 위한 스위치장치의 제어회로에 관한 것이다.The present invention relates to a control circuit of a switch device for solving this problem.

본 발명에 의한 회로의 배치를 도면에 따라 상세히 설명하면 다음과 같다. 제1도에서 알수 있는 바, 전원스위치(1), 소비기기(3) 및 변압기(4)는 도선(2)에 의해서 서로 연결되어 있다. 변압기(4)의 출력부에는 부하(5)가 연결되어 있고 그의 출력부에는도선(2)에 흐르는 전류에 비례하는 규정된 전압이 유지되게 된다. 부하(5)는 아날로그-디지탈변환기(6)에 연결되어 있어서 여기에서 전술한 전압이 디지탈 신호로 변환된다.Referring to the arrangement of the circuit according to the present invention in detail as follows. As can be seen in FIG. 1, the power switch 1, the consumer device 3 and the transformer 4 are connected to each other by a conductor 2. A load 5 is connected to the output of the transformer 4 and at its output a defined voltage is maintained which is proportional to the current flowing in the conductor 2. The load 5 is connected to the analog-digital converter 6 so that the above-mentioned voltage is converted into a digital signal.

매번의 디지탈 신호때 마다 전원스위치(1)의 개폐부분의 감량(減量 : 스위치 개폐시)의 값이 반도체 축전지(7)에 의하여 선별되고 동시에 축전지(7)에는 전류의 진폭에 비례하는 감량값이 저장된다. 반도체 축전지(7)에 의한 감량값의 선별은 전원스위치(1)가 차단될 때 솔모양의 접촉부를 지닌 보조스위치 접촉기(10)가 스위치 임펄스(impulse)를 가함으로써 일어난다. 이 순간도선(2)에 흐르는 전류에 대응되는 값이 가산(加算)단계(11)에 연결되어 여기에 저장된다. 따라서 가산단계(11)의 저장량은 선별된 감량의 총 합계를 나타낸다.Each time the digital signal is lost, the value of the opening and closing portion of the power switch 1 is selected by the semiconductor battery 7, and at the same time, the battery 7 has a weight loss proportional to the amplitude of the current. Stored. Selection of the weight loss value by the semiconductor storage battery 7 occurs when the auxiliary switch contactor 10 having a brush-shaped contact portion applies a switch impulse when the power switch 1 is shut off. The value corresponding to the current flowing in the instantaneous conductor 2 is connected to the addition step 11 and stored therein. Therefore, the storage amount of the addition step 11 represents the total sum of the selected weight loss.

이어 비교단계(12)와 표준값 축전지(13)이 있는데 비교단계(12)는 가산단계(11)의 저장량을 표준값 축전지(13)가 만들어내는 표준값과 비교한다. 그 결과 저장량이 표준값을 넘어서면 비교단계(12)의 출력(14)에 신호가 발생되는데 이 신호는 지시, 또는 보다 나은 보호조처를 위하여 이용될 수 있는 것이다.Then, there is a comparison step 12 and a standard value storage battery 13. The comparison step 12 compares the storage amount of the addition step 11 with the standard value produced by the standard value storage battery 13. As a result, when the storage amount exceeds the standard value, a signal is generated at the output 14 of the comparison step 12, which can be used for indication or for better protection.

도면에서 점선으로 표시된 부분은 감량의 정확한 포착을 나타낸다. 발진기(15)는 소손량을 보다 정확하게 구하기 위해서 설치하는 데, 왜냐하면 접점의 소손량은 전류치 뿐만 아니라 정확히 말하자면 전류치와 그 지속시간의 곱(전류치×지속시간)에 비례하므로, 보조개폐기(16)를 이용해서, 스위치(1)가 열리기 시작해서 완전히 열릴때까지 발진기(15)를 구동시킴으로써 아아크지속시간도안에 반도체 축전지(7)와 가산회로(11)에 그 발진기(15)의 출력이 공급되도록 하여, 단순히 스위치의 개폐시에 발생하는 전류치와 아울러 아아크 지속시간동안에 발진기(15)에서 펄스가 올 때 마다 그 펄스의 전류치에 대응하는 출력이 반도체 축전지(7)로부터 가산단계(11)로 가해지게 된다. 따라서, 가산단계(11)는 아아크 지속시간과 전류치와의 곱에 비례하는 값을 가산하게 된다.The portion indicated by the dotted line in the figure indicates the accurate capture of the weight loss. The oscillator 15 is installed in order to more accurately calculate the amount of burnout, because the amount of burnout of the contact is not only the current value, but also precisely proportional to the product of the current value and its duration (current value × duration), so that the auxiliary switch 16 By driving the oscillator 15 until the switch 1 starts to open and fully opens, the output of the oscillator 15 is supplied to the semiconductor storage battery 7 and the addition circuit 11 within the arc duration time diagram. Whenever a pulse is generated from the oscillator 15 during the arc duration, the output corresponding to the current value of the pulse is simply applied to the addition step 11 from the semiconductor storage battery 7. . Therefore, the adding step 11 adds a value proportional to the product of the arc duration and the current value.
