Description

누전차단기용 조작노브의 자동 리턴 장치 {Device for returning the knob of earth leakage circuit breakers}Automatic return device of operation knob for earth leakage breaker {Device for returning the knob of earth leakage circuit breakers}

본 발명은 누설전류 등으로 인하여 발생하는 안전사고를 예방시키는 누전차단기에 관한 것으로, 특히 누전차단기에 구성되어 전원을 차단하는 조작노브의 리턴과정이 자동으로 이루어지게하여 편리성을 증대시킬 수 있도록 된 누전차단기용 조작노브의 자동 리턴 장치에 관한 것이다.The present invention relates to an earth leakage circuit breaker that prevents a safety accident caused by leakage current, and the like, and is particularly constructed to the earth leakage circuit breaker so that the return process of the operation knob to cut off the power is automatically made to increase convenience. An automatic return device for an earth leakage breaker operating knob.

일반적으로, 누전차단기는 분전반내에 설치되어 누전 등과 같은 누설전류가 발생하는 자동으로 전원을 차단하는 안전장치로서, 이러한 누전차단기는 인체의 감전 사고나 누전에 의한 화재 및 과전류와 단락 등에 의한 안전사고 등을 예방하기 위한 목적으로 사용되는 전장품의 일종이다.In general, an earth leakage breaker is a safety device that is installed in a distribution panel and automatically cuts off power when a leakage current such as an electric leakage occurs. It is a kind of electrical equipment used for the purpose of preventing the damage.

여기서, 현대사회에는 유무선 및 인터넷 등과 같은 원격제어에 의해 작동하는 누전차단기가 많이 연구되고 있으며, 특히 누전차단기의 온/오프동작에 따른 작동이 용이해야 함은 물론 시스템의 오작동이 없어야 할 뿐만 아니라 조립성이 간편한 구조의 제품들이 연구중에 있다.Here, a lot of earth leakage breakers operated by remote control such as wired / wireless and internet are being studied in modern society. Especially, the earth leakage breaker should be easy to operate according to the on / off operation of the earth leakage breaker. Products with simple structures are being researched.

예컨대, 본원 출원인에 의한 고안된 "개폐장치"(등록번호: 20-0353051호)에 의하면, 개폐기(100)의 내부에 노브(103)의 개폐과정에서 힌지(141)를 따라 회전함은 물론 솔레노이드밸브(107)의 플런져(115)가 힌지결합되어 연동하는 노브바디(113)가 설치되면서, 상기 개폐기(100)의 바닥면에 힌지(135)를 따라 회전함은 물론 그 몸체에 샤프트(133)를 장착한 지지대(111)가 설치되며, 상기 노브바디(110)의 힌지(141)에 노브(103)의 회전력을 통해 회전하면서 스프링(123)을 통해 리턴함은 물론 그 선단부에 샤프트(133)와 맞닿는 제1.2가압부(221.223)를 구비한 활대(105)가 설치된 구성이 제안된 바 있다.For example, according to the "opening and closing device" (Registration No .: 20-0353051) devised by the applicant of the present application, the solenoid valve as well as rotates along the hinge 141 in the opening and closing process of the knob 103 inside the switch 100 While the plunger 115 of the 107 is hinged coupled to the knob body 113 is installed, the shaft 133 rotates along the hinge 135 on the bottom surface of the switch 100 as well. Is mounted on the support 111, the hinge 141 of the knob body 110 by rotating through the rotational force of the knob 103 while returning through the spring 123, as well as the shaft 133 at the front end thereof. There has been proposed a configuration in which a slide 105 having a 1.2 th pressing portion 22.

따라서, 솔레노이드밸브(107)에 전원이 공급되는 경우, 플런져(115)에 의해 노브바디(113)가 힌지(141)를 중심으로 회동하고, 이 노브바디(113)의 후면에 장착된 구동폴(117)이 연동되어 접촉스위치(109)를 오프동작시키므로, 개폐기(100)가 자동으로 접촉스위치(109)를 트립시키는 것이다.Therefore, when power is supplied to the solenoid valve 107, the knob body 113 is rotated about the hinge 141 by the plunger 115, the drive pole mounted on the rear of the knob body 113 Since the 117 is interlocked to turn off the contact switch 109, the switch 100 automatically trips the contact switch 109.

동시에, 노브바디(113)에 장착된 활대(105)가 연동하여 지지대(111)의 샤프트(133)를 햐향으로 가압시키므로, 활대(105)의 선단부를 이루는 제2가압부(223)와 샤프트(133)가 맞닿아 지지대(111)가 안정상태로 세팅되는 것이다.At the same time, the shaft 105 mounted on the knob body 113 is interlocked to press the shaft 133 of the support 111 in the opposite direction, so that the second pressing portion 223 and the shaft ( 133 is in contact with the support 111 is set to a stable state.

반면, 솔레노이드밸브(107)의 전원이 차단되는 경우, 플런져(110)가 리턴되어 노브바디(113)가 리턴되므로, 구동폴(117)과 접촉스위치(109)가 접촉하여 "온"작동되며, 활대(105)가 스프링(125)에 의해 리턴되고 지지대(111)는 스프링(123)에 의해 리턴되어 개폐기(100)가 정상 작동하는 것이다.On the other hand, when the power supply of the solenoid valve 107 is cut off, since the plunger 110 is returned and the knob body 113 is returned, the driving pole 117 and the contact switch 109 come into contact with each other to operate "on". The shaft 105 is returned by the spring 125 and the support 111 is returned by the spring 123 so that the switch 100 is normally operated.

그런데, 개폐기(100)는 솔레노이드밸브(107)를 이용하여 이상전류의 차단을 가능하게 하는 장점은 있지만, 노브바디(113)에 솔레노이드밸브의 플런져(115)가 직접 힌지식으로 결합되어 연동하는 상태이므로, 노브바디(113)의 리턴에 따른 하중을 미처 흡수하지 못하여 작동소음이 발생됨은 물론 부정확한 작동이 이루어져 신뢰성이 저하되는 문제점이 있었다.By the way, although the switch 100 has the advantage of blocking the abnormal current by using the solenoid valve 107, the plunger 115 of the solenoid valve is directly hinged to the knob body 113 to interlock. Since it is in a state, the noise due to the return of the knob body 113 may not be absorbed, resulting in operation noise as well as inaccurate operation resulting in a decrease in reliability.

그리고, 개폐기(100)에서 솔레노이드밸브(107)의 작동 안정성을 증대시키기위한 수단으로서 활대(105)와 지지대(111)에 제1.2가압부(121.123)와 샤프트(133)를 각각 형성시켜야 함은 물론 리턴수단으로 스프링(123.125)을 설치해야하므로 각종 부대비용이 증대되는 문제점이 있었다.In addition, as a means for increasing the operational stability of the solenoid valve 107 in the switchgear 100, the 1.2 pressurizing part 121.123 and the shaft 133 should be formed in the slide 105 and the support 111, respectively. Since the spring (123.125) to be installed as a return means there was a problem that various additional costs increase.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위하여 안출된 것으로서, 누전차단기에 구성되어 전원을 차단하는 조작노브의 리턴과정이 자동으로 이루어지게 하여 사용상 편리성을 증대시킬 수 누전차단기용 조작노브의 자동 리턴 장치를 제공하는 데에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the problems described above, it is configured to the earth leakage breaker, the return process of the operation knob to cut off the power is automatically made to increase the convenience in use for the earth leakage breaker operation The purpose is to provide an automatic return device for the knob.

먼저, 누전차단기(10)의 솔레노이드밸브(25)에 서지전류가 인가되어 전자력을 발생시키는 경우, 도 2b에서와 같이 플런져(25a)가 흡인되므로, 플런져(25a)에 구동링크(23)를 통해 연결된 회동레버(22)가 반시계방향으로 회동한다.First, when a surge current is applied to the solenoid valve 25 of the earth leakage breaker 10 to generate an electromagnetic force, the plunger 25a is sucked as shown in FIG. 2B, and thus, the drive link 23 is connected to the plunger 25a. The rotating lever 22 connected through rotates counterclockwise.

이로 인해, 회동레버(22)에 피동링크(24)를 통해 연결된 조작노브(14)가 당겨져 반시계방향으로 회동하는 것이다.For this reason, the operation knob 14 connected to the rotation lever 22 via the driven link 24 is pulled and rotated counterclockwise.

더불어, 조작노브(14)에 피동링크(24)를 통해 연결된 트립바(15)가 하향하므로, 트립바(15)에 장착되어 있던 누름봉(15a)이 접접스위치(16)를 눌러 누전차단기를 "온"상태로 유지시키는 것이다.In addition, since the trip bar 15 connected to the operation knob 14 through the driven link 24 is downward, the push bar 15a mounted on the trip bar 15 presses the contact switch 16 to close the earth leakage breaker. Keep it "on".

한편, 솔레노이드밸브(25)에 인가된 서지전류가 일정시간이 경과되어 사라지는 경우 도 2a에서와 같이 플런져(25a)가 돌출되므로, 플런져(25a)에 구동링크(23)를 통해 연결된 회동레버(22)가 시계방향으로 회동한다.On the other hand, when the surge current applied to the solenoid valve 25 disappears after a predetermined time elapses, as shown in FIG. 2A, the plunger 25a protrudes, and thus, the rotation lever connected to the plunger 25a through the drive link 23. (22) rotates clockwise.

이로 인해, 회동레버(22)에 피동링크(24)를 통해 연결된 조작노브(14)가 시계방향으로 회동하는 것이다.For this reason, the operation knob 14 connected to the rotation lever 22 via the driven link 24 rotates clockwise.

더불어, 조작노브(14)에 피동링크(24)를 매개로 연결된 트립바(15)가 상향하므로, 접촉스위치(16)를 누르고 있던 누름봉(15a)이 원상태로 리턴되어 누전차단기를 "오프"상태로 유지시키는 것이다.In addition, since the trip bar 15 connected to the operation knob 14 via the driven link 24 is upward, the push bar 15a holding the contact switch 16 is returned to its original state so that the earth leakage breaker is "off". Keep it in a state.

이상에서 설명한 바와 같이 본 발명에 따른 누전차단기용 조작노브의 자동 리턴 장치에 의하면, 누전차단기에 구성되어 힌지축을 따라 회동하는 조작노브의 복귀과정이 자동으로 이루어지므로써, 누전차단기가 "온"된 상태에서 일정시간이 경과되는 경우 솔레노이드의 지속적인 구동 전류 없이도 자동으로 조작노브가 리턴되어 누전차단기에서 메커니즘을 구현에 따른 소비전력이 최소화될 뿐만 아니라 전원의 지속적인 차단으로 인해 발생하는 음식물의 부패 등과 같은 부가적인 손실이 최소화되는 효과가 있는 것이다.As described above, according to the automatic return device of the earth leakage breaker operating knob according to the present invention, the earth leakage breaker is “on” because the return process of the operating knob rotated along the hinge axis is automatically performed. If a certain time elapses in the state, the operating knob is automatically returned without the continuous drive current of the solenoid, minimizing the power consumption by implementing the mechanism in the ground fault circuit breaker, and also adding foods such as food decay caused by the continuous interruption of the power supply. This is to minimize the loss.
