본 발명은 서지보호기에 관한 것으로 상세하게는 과부하에 의해 서지보호기가 손상되는 것을 방지할 수 있도록 과전류차단수단이 일체화된 서지보호기에 관한 것이다. 특히, 과전류차단수단을 복귀시킬 수 있게 하여 과전류가 해소된 후 다시 사용할 수 있게 한 과전류차단기 기능을 구비한 서지보호기에 관한 것이다.
The present invention relates to a surge protector, and more particularly, to a surge protector in which an overcurrent blocking means is integrated to prevent the surge protector from being damaged by an overload. In particular, the present invention relates to a surge protector having an overcurrent breaker function, which enables the overcurrent blocking means to be restored so that the overcurrent is eliminated and then used again.

서지(surge)란 라인 또는 회로를 따라서 전달되며, 급속히 증가하고 서서히 감소하는 특성을 지닌 전기적 전류, 전압 또는 전력의 과도파형을 일컫는 것으로서, 우리 주변에서 흔히 발생하는 현상 중 하나이다. 예를 들어 벼락이 떨어질 경우 낙뇌(Lightning) 서지는 전자기기를 파괴시키며, 스위치, 릴레이, 용접 등의 아크(arc)와 단락에 의한 개폐 서지, 모터엘리베이터 등의 구동 서지 등 우리 주변에서는 끊임없이 서지가 발생한다. 이러한 서지 중 약한 서지가 반복될 경우 전기/전자 소자를 열화시켜 소자의 노후를 가속화시키고, 강한 서지의 경우 장치나 소자를 파괴한다. Surge is a transient waveform of electrical current, voltage, or power that is transmitted along a line or circuit and has a rapidly increasing and slowly decreasing characteristic, which is one of the phenomena commonly occurring around us. For example, when lightning strikes, lightning surges destroy electronic devices, and surges constantly occur around us, such as arcs such as switches, relays, and welding, and open and close surges caused by short circuits and driving surges such as motor elevators. Occurs. If one of these surges is repeated, the electrical / electronic device is degraded to accelerate the aging of the device, and the strong surge destroys the device or device.

이러한 서지가 부하를 통해 흐르지 않고 자신을 통해 흐르게 하여 부하를 보호할 수 있도록 배선에는 서지보호기가 설치되어 있다. Surge protectors are installed in the wiring so that these surges do not flow through the load, but through themselves to protect the load.

아울러, 누전이나 기타의 원인에 의해 정격전류 이상의 과전류가 흐를 때 이로 인한 사고를 예방하기 위해 전류의 흐름을 차단하는 수단으로 차단기가 있다. In addition, there is a circuit breaker as a means for blocking the flow of current in order to prevent an accident caused when an overcurrent above the rated current flows due to a short circuit or other causes.

이러한 차단기와 서지보호기는 따로 구성되어 있으므로 설치공간을 많이 차지할 뿐만 아니라 설치에 많은 번거로움이 있었다. Since these breakers and surge protectors are configured separately, they take up a lot of installation space and have a lot of trouble in installation.

또한, 서지보호기를 과전류로부터 보호하기 위해서는 서지보호기의 전단에 퓨즈나 차단기를 별로도 설치하여야 하므로 전체 배선이 복잡해지고, 서지보호기를 보호하기 위한 별도로 설치된 퓨즈나 차단기는 한번 사용하면 다시 사용할 수 없는 문제가 있었다.
In addition, to protect the surge protector from overcurrent, fuses or circuit breakers must be separately installed at the front of the surge protector, and the entire wiring becomes complicated, and a separately installed fuse or circuit breaker to protect the surge protector cannot be used again. There was.

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위해 개발된 것으로써, 배선용 차단기와 일체화되어 구성이 단순하고 시공이 용이한 서지보호기를 제공하는 것을 목적으로 한다. The present invention was developed to solve the problems of the prior art as described above, and an object of the present invention is to provide a surge protector which is integrated with a circuit breaker and is simple in construction and easy to construct.

특히, 서지보호기를 과부하로부터 보호하는 과부하 차단부를 스위치 형태로 구성하여 과부하가 해소된 후에 다시 접속시켜 사용할 수 있게 한 서지보호기를 제공하는 것을 목적으로 한다.
In particular, it is an object of the present invention to provide a surge protector configured to switch overload protection unit that protects the surge protector from overload in the form of a switch so that the surge protector can be connected and used again after the overload is eliminated.

전술한 목적을 달성하기 위한 본 발명에 따른 과전류차단기 기능을 구비한 서지보호기는 과전류 차단과 서지 전류를 흡수하는 차단기 일체형 서지보호기에 있어서, 상용 전원이 연결되는 하나 이상의 전원입력단자(In)와 부하가 연결되는 부하연결단자(Out)사이의 전원공급라인 중간에 연결되고 두 개의 접점(S1, S2)를 구비한 스위칭수단과; 상기 스위칭수단을 통해 상기 전원공급라인과 접지단자(G) 사이에 병렬로 연결된 바리스터를 포함하는 것을 특징으로 한다.
In order to achieve the above object, a surge protector having an overcurrent breaker function according to the present invention is a circuit breaker integrated surge protector that absorbs overcurrent and surge current, and includes one or more power input terminals (In) and a load to which commercial power is connected. Switching means connected between a load supply terminal (Out) connected to the middle of a power supply line and having two contacts (S1, S2); It characterized in that it comprises a varistor connected in parallel between the power supply line and the ground terminal (G) through the switching means.

본 발명은 배선용 차단기 역할을 하는 스위칭 수단이 일체로 구비되어 차단기를 별도로 설치하지 않아도 되므로 배선이 단순해 배선작업을 용이하게 할 수 있는 효과가 있다. According to the present invention, since the switching means serving as a circuit breaker are integrally provided, the circuit breaker does not need to be separately installed, so that the wiring is simple, thereby facilitating the wiring work.

더욱이, 리셋버튼을 구비하여 과전류 발생 원인이 해소된 후 리셋하여 다시 사용할 수 있으므로 차단기나 서지보호기를 교체하지 않아도 됨으로 이들을 교체하는데 소요되는 비용을 절감할 수 있는 효과가 있다.
Moreover, since the cause of the overcurrent is eliminated by the reset button, it can be reset and used again, thereby eliminating the need to replace the breaker or surge protector, thereby reducing the cost of replacing them.

도 1은 본 발명에 따른 서지보호기의 구성도이다.1 is a block diagram of a surge protector according to the present invention.

이하 첨부된 도면을 참조하여 본 발명을 보다 상세히 설명한다. 그러나 첨부된 도면은 본 발명의 기술적 사상의 내용과 범위를 쉽게 설명하기 위한 예시일 뿐, 이에 의해 본 발명의 기술적 범위가 한정되거나 변경되는 것은 아니다. 또한 이러한 예시에 기초하여 본 발명의 기술적 사상의 범위 안에서 다양한 변형과 변경이 가능함은 당업자에게는 당연할 것이다.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings. It should be understood, however, that the appended drawings illustrate only the contents and scope of technology of the present invention, and the technical scope of the present invention is not limited thereto. In addition, it will be apparent to those skilled in the art that various modifications and changes can be made within the scope of the present invention based on these examples.

본 발명은 배선용 차단기와 서지보호기를 일체화하여 배선 작업을 용이하게 할 수 있음은 물론 리셋하여 반복적으로 사용할 수 있는 서지보호기에 관한 것으로 부하에 공급되는 과전류는 물론 서지보호기에 과전류가 공급되지 않게 하기 위한 스위칭수단(1)을 포함하여 구성된다. The present invention relates to a surge protector that can be wired easily by resetting the circuit breaker and the surge protector, as well as to reset the surge protector, so that the overcurrent supplied to the load as well as the overcurrent is not supplied to the surge protector. It comprises a switching means (1).

이러한 본 발명에 의한 과전류차단기 기능을 구비한 서지보호기는 도 1에 도시한 바와 같이 전원입출력단자(In, Out)와 접지단자(G)를 구비하고 있다. As shown in FIG. 1, the surge protector having the overcurrent breaker function according to the present invention includes power input / output terminals In and Out and a ground terminal G. As shown in FIG.

상기 스위칭수단(1)은 전원입출력단자들 사이에 설치되어 과전류가 부하에 공급되거나, 서지보호수단(바리스터, 이하"바리스터"라 통칭한다)으로 흐르는 것을 차단하는 역할을 한다. The switching means 1 is installed between the power input and output terminals to block the overcurrent from being supplied to the load or flowing to the surge protection means (hereinafter referred to as "varistor").

즉, 과전류가 발생되면 상기 스위칭수단(1)이 작동하여 전원공급라인을 단락시키고 이때 바리스트(2)로 흐르는 과전류도 차단되는 것이다. That is, when an overcurrent occurs, the switching means 1 operates to short the power supply line, and at this time, the overcurrent flowing to the bar list 2 is also cut off.

이렇게 과전류 발생시 부하와 바리스터로 전류가 흐르는 것을 차단할 수 있도록 상기 스위칭수단(1)은 상용 전원이 연결되는 하나 이상의 전원입력단자(In)와 부하가 연결되는 부하연결단자(Out)사이의 전원공급라인 중간에 연결되고 두 개의 접점(S1, S2)를 구비하고 있으며, 상기 바리스터(2)는 스위칭수단(1)을 통해 상기 전원공급라인과 접지단자(G) 사이에 병렬로 연결된다.The switching means 1 is a power supply line between at least one power input terminal (In) to which the commercial power is connected and the load connection terminal (Out) to which the load is connected so that current flows to the load and the varistor when the overcurrent occurs. It is connected in the middle and has two contacts (S1, S2), the varistor (2) is connected in parallel between the power supply line and the ground terminal (G) via a switching means (1).

상기 스위칭수단으로는 다양하게 변형하여 실시 할 수 있으나 바람직하게는 도 1에 도시한 바와 같이 과전류에 의해 자화되어 두 접점(S1, S2)의 접속을 단락시키는 코일(12)를 포함하여 구성하는 것이 바람직하다. The switching means may be modified in various ways. Preferably, the switching means includes a coil 12 that is magnetized by an overcurrent to short-circuit the connection between the two contacts S1 and S2. desirable.

상기 코일(12)은 코어에 복수로 감긴 구조로 정상적인 전류가 흐를 때는 코어가 자화되지 않거나 자화된다하더라도 접점(S2)를 작동시킬 수 없는 정도의 자력을 발생시키고, 과전류가 흐르면 코어가 자화되어 접점(S2)를 작동시켜 접점(S1)으로부터 분리되게 한다. The coil 12 has a plurality of structures wound around the core. When a normal current flows, the coil 12 generates a magnetic force that cannot operate the contact S2 even if the core is not magnetized or magnetized. Operate (S2) to separate from the contact (S1).

즉, 도 1에서 점선으로 표시한 바와 같이 정상적인 전류가 흐를때는 두 점점(S1, S2)이 서로 접속되어 전원이 부하에 공급됨은 물론 바리스터(2)에서도 이 전원이 인가되고, 낙뢰 등의 서지가 발생되면 서지가 바라스터(2)에 의해 흡수되는 것이다. That is, as shown by the dotted line in Fig. 1, when the normal current flows, two progressively (S1, S2) are connected to each other and the power is supplied to the load, and the power is also applied to the varistor 2, and a surge such as a lightning strike is applied. When generated, the surge is absorbed by the varistor (2).

그러나 과전류가 흐르게 되면 코어에 자력이 발생되어 접점(S2)이 접점(S1)으로부터 분리되어 부하 및 바리스터(2)로 전기가 흐리지 않게 되어 부하는 물론 바리스터가 보호되는 것이다. However, when an overcurrent flows, magnetic force is generated in the core so that the contact S2 is separated from the contact S1 so that electricity does not flow to the load and the varistor 2 so that the load and the varistor are protected.

또한 본 발명은 상기 스위칭수단(1)을 원상태로 복귀시키기 위한 리셋버튼(11)을 더 구비하고 있다. In addition, the present invention further comprises a reset button 11 for returning the switching means 1 to its original state.

상기 리셋버튼(11)은 과전류를 발생시키는 원인이 해소된 후 다시 두 접점(S1, S2)을 접속시키기 위한 수단으로 누르거나 당기면 두 접점(S1, S2)이 다시 접속되어 전원이 부하와 바리스터에 공급되는 것이다. The reset button 11 is a means for connecting the two contacts (S1, S2) again after the cause of the overcurrent is eliminated, and if the two contacts (S1, S2) are connected again, the power is connected to the load and the varistor. It is supplied.

도 1에는 단일 전원공급라인만을 도시하였으나 이는 하나의 예이고 각각의 전원공급라인에 선택적으로 설치될 수 있음은 본 발명이 속하는 분야에 종사하는 자에게는 쉽게 이해될 수 있는 것으로 이에 대한 상세한 설명은 생략한다.
Although only a single power supply line is shown in FIG. 1, this is only one example and can be selectively installed in each power supply line, which can be easily understood by those skilled in the art to which the present invention pertains. do.
