본 발명은 지하에 매설되는 다수의 금속구조물을 방식하기 위한 전기방식(電氣防蝕)설비에 관한 것으로, 구체적으로는 지하에 매설되는 다수의 금속구조물과, 방식전류를 공급하기 위한 정류기 사이에 가변저항을 설치하여 각 금속구조물로 유입되는 방식전류의 양이 균일하도록 조절 가능한 전기방식장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical anticorrosion facility for corrosion protection of a plurality of metal structures buried underground. Specifically, a variable resistor is provided between a plurality of metal structures embedded underground and a rectifier for supplying corrosion protection current. The present invention relates to an electrical anticorrosion apparatus that can be adjusted so that the amount of anticorrosive current flowing into each metal structure is uniform.

전기방식이란, 피방식체의 전위를 인위적으로 조절하여 부식반응인 양극반응을 억제하는 것으로서, 일반적으로 금속의 피방식체가 부식되는 경우 일종의 전지반응이 일어나며 이온화 경향이 큰 부분이 용해되므로, 금속의 피방식체에 외부에서 인위적으로 전류(방식전류)를 유입시키면 전위가 높은 음극부는 전류가 유입되어 전위가 차차 저하되다가 양극부의 전위에 가까워지고 결국 음극부와 양극부의 전위가 동일하게 되어 피방식체의 부식을 방지하는 것이다.The electric method is to artificially control the potential of the object to inhibit the anodic reaction, which is a corrosion reaction. In general, when the metal object is corroded, a kind of battery reaction occurs and a large part of the ionization tends to dissolve. When an external current (corrosive current) is artificially introduced into the object to be subjected to the external object, the cathode part having a high potential flows into the current, and the potential gradually decreases, and the potential closes to the potential of the anode part. To prevent corrosion.

상기한 전기방식은 방식전류의 공급방식에 따라 희생양극법과 외부전원법의 두 가지 형태로 대별된다.The electric system is roughly divided into two types, the sacrificial anode method and the external power supply method, depending on the supply method of the anticorrosive current.

희생양극법은 피방식체보다 저전위의 금속을 피방식체에 직접 또는 도선으로 연결하고 양 금속간에 전지반응이 발생되면, 저전위의 금속에서 금속이온이 용출되어 피방식체로 전류가 인입되게 하는 방법으로 유전양극법이라고도 한다.The sacrificial anode method connects a metal with a lower potential than that of the object directly or by conducting wire, and if a battery reaction occurs between both metals, metal ions are eluted from the metal with low potential to draw current into the object. It is also called genetic anode method.

외부전원법은 피방식체가 위치되는 전해질(해수, 담수 또는 토양 등)에 양극을 설치하여 상기 양극에 외부로부터 별도로 공급되는 직류전원의 양극을 연결하고, 음극은 피방식체에 연결하여 방식전류를 공급하는 방법으로 상기 직류전원으로는 정류기를 사용하며, 통상적으로 가장 많이 사용되는 방식방법이다.In the external power method, a positive electrode is installed in an electrolyte (sea water, fresh water or soil, etc.) in which the object is located, and the anode of the DC power supplied separately from the outside is connected to the anode. As a supplying method, a rectifier is used as the DC power supply, which is usually the most commonly used method.

도 1a와 도 1b는 다수의 금속구조물 혹은 다수의 강파일들을 하나의 정류기를 사용하여 상기 외부전원법으로 전기방식을 수행할 때에 기존에 설치하는 방법을 나타낸 것이다.1A and 1B illustrate a conventional method of installing a plurality of metal structures or a plurality of steel piles by using a single rectifier when performing an electric method using the external power method.

도 1a와 도1b에 도시된 바와 같이, 지하에 다수개의 금속구조물(P) 혹은 다수의 강파일이 매설되어 있고, 상기 금속구조물(P)에 방식전류를 인가하기 위해 교류전원을 직류로 변환시키는 정류기(10)가 외부에 설치되며, 상기 금속구조물(P)이 위치한 지중에 상기 정류기(10)의 양극단자과 연결되는 심매양극(20)이 위치한다.1A and 1B, a plurality of metal structures P or a plurality of steel piles are buried underground, and the AC power is converted into direct current to apply anticorrosive current to the metal structures P. The rectifier 10 is installed outside, and the core anode 20 connected to the anode terminal of the rectifier 10 is located in the ground where the metal structure P is located.

상기 금속구조물(P)은 상기 정류기(10)의 음극과 음극선을 통해 직렬 또는 병렬의 형태로 연결되고, 상기 심매양극(20)은 상기 정류기(10)의 양극단자와 양극선을 통하여 직접 연결되며, 상기 심매양극(20)을 통해 발산되는 방식전류는 상기 금속구조물(P)이 매설된 토양을 전해질로 하여 상기 금속구조물(P)에 유입되는 방식으로 인가된다.The metal structure (P) is connected in series or parallel form through the cathode and the cathode of the rectifier 10, the core anode 20 is directly connected through the anode terminal and the anode line of the rectifier 10, The anticorrosive current emitted through the core anode 20 is applied in such a way that the metal structure P is introduced into the metal structure P using the soil in which the metal structure P is embedded as an electrolyte.

상기와 같은 외부전원법을 이용한 방식장치는 효과범위가 넓어 대규모 구조물에 효과적이지만, 도 1a와 도 1b에서와 같이 다수의 매설된 금속구조물을 1개의 정류기를 사용하여 외부전원법으로 방식하고자 할 때 양극단자와 금속구조물의 간격, 정류기와 금속구조물 사이에 연결한 리드선의 길이, 각각의 금속구조물의 피복 상태 등에 따라서 각각의 금속구조물에 유입되는 방식전류량의 크기가 다를 수 있으며, 이러한 원인으로 인하여 일부 구조물은 방식이 과하게 되고, 또 다른 일부 구조물은 방식이 모자라는 경우도 발생하게 된다.Corrosion apparatus using the external power method as described above is effective in large-scale structures because the effect range is wide, but when to embed a plurality of buried metal structures using an external power method using a single rectifier as shown in Figure 1a and 1b Depending on the gap between the anode terminal and the metal structure, the length of the lead wire connected between the rectifier and the metal structure, and the covering state of each metal structure, the magnitude of the anticorrosive current flowing into each metal structure may vary. Structures will be overly modal, and some other structures may be deficient.

따라서, 본 발명의 목적은 상술한 제반 문제점을 해결하기 위한 것으로, 다수의 금속구조물이 모두 적절한 방식상태를 유지하도록 피방식체인 금속구조물과 정류기 사이에 저항을 설치하여 각 금속구조물로 유입되는 방식전류의 양이 조절 가능한 전기방식장치를 제공하는데 있다.Accordingly, an object of the present invention is to solve the above-mentioned problems, and installs a resistance between the metal structure and the rectifier to be a corrosion-resistant body to maintain a proper anticorrosive state of all the metal structure, the anticorrosive current flowing into each metal structure The present invention provides an electric device with an adjustable amount of.
