It relates to a ground rod formed with a plurality of blades.

접지란 통신장비, 전자계측장비, 피뢰장비 및 전력장비 등을 전기적으로 대지와 접속시켜 주는 것을 말하는 것으로, 접지에 의해 장비와 대지가 전기적으로 접속되어 장비에 가해지는 과부하나 낙뢰 등에 의한 써지(SERGE)를 대지로 흘려보낼 수 있게 한다. 즉, 접지에 의해 장비가 과부하 및 써지전압에 의해 손상되는 것을 방지토록 함에 있다.Grounding refers to the electrical connection between communication equipment, electronic measurement equipment, lightning protection equipment, and power equipment, etc., and the surge caused by the overload or lightning applied to the equipment by grounding the equipment and the ground electrically. ) Can be sent to the ground. That is, to prevent the equipment from being damaged by overload and surge voltage by grounding.

상기 접지는 공통접지와 독립접지 등의 시공방식이 있다. 상기 독립접지는 도3b에 도시된 바와 같이, 접지를 필요로 하는 각각의 접지설비(50)를 개별적으로 접지봉(10)과 리드선(40)을 통해 접속하는 방식으로 각각의 장비나 설비에 개별적으로 시공한 접지를 독립접지 또는 단독접지라 한다. 여기서 피뢰설비(60)도 또한 개별적으로 접지봉(10)과 리드선(40)으로 연결되어 시공된다.The ground has a construction method such as common ground and independent ground. As shown in FIG. 3B, the independent ground is individually connected to each equipment or facility by connecting each grounding facility 50 requiring grounding individually through the ground rod 10 and the lead wire 40. Constructed ground is called independent ground or single ground. Here, the lightning arrester 60 is also separately connected to the ground rod 10 and the lead wire 40 is constructed.

그리고 상기 공통접지는 도3b에 도시된 바와 같이, 여러 다른 시설인 접지설비(50)를 하나의 접지전극을 구성하여 공통으로 접지봉(10)에 접속하여 사용하는 접지방식이다. 이 때 뇌전류는 전류량이 크고 지속시간이 극히 짧은 특성으로 인해 피뢰설비(60)는 연접선(45)과 연결시켜 접지하게 된다.As shown in FIG. 3B, the common ground is a grounding method in which the grounding facility 50, which is a different facility, is connected to the grounding rod 10 by forming one grounding electrode. At this time, the lightning current has a large amount of current and extremely short duration, so that the lightning arrester 60 is connected to the connection line 45 to ground.

상기 독립접지와 공통접지는 각각의 장점과 단점이 있으며, 이는 접지가 시 공되는 대지의 대지저항과 접지저항 및 접지구성에 따라 각각 선별적으로 시공되고 있으며, 미국이나 유럽에서서는 공통접지 방식이 권고되고 있다.The independent ground and the common ground have their advantages and disadvantages, which are selectively constructed according to the earth resistance, ground resistance, and ground configuration of the ground on which the ground is constructed. It is recommended.

상기 독립접지와 공통접지에서는 다양한 형상의 접지봉을 사용하고 있는데, 상기 접지봉은 일정 직경과 길이를 갖는 원기둥 형상의 일반 접지봉을 주로 사용하며, 상기 일반 접지봉은 순동으로 형성되거나 동으로 피복처리된 것을 사용한다.The independent ground and the common ground use ground rods of various shapes. The ground rod mainly uses a cylindrical ground rod having a predetermined diameter and length, and the ground rod is formed of pure copper or coated with copper. do.

또한 다양한 대지저항에 대처하고 주위 환경변화에 관계없이 안정적으로 낮은 접지저항을 유지시켜 주고 순간 전위상승을 억제하여 서지 임피던스를 감소시켜주는 복합형 접지시스템으로 방사항 전해질 접지시스템(DAD; Discharge And Dispersion grounding system)이 사용되며, 이 때 사용되는 접지봉은 순간전위상승을 억제하고 방전시켜 주는 첨단부가 복수개 형성된 것을 사용한다.In addition, it is a complex grounding system that copes with various earth resistances and maintains a low grounding resistance stably regardless of changes in the surrounding environment, and reduces surge impedance by suppressing the instantaneous potential rise. grounding system) is used, and the ground rod used in this case is formed by using a plurality of tips formed to suppress and discharge an instantaneous potential rise.

한펀, 대지저항이 높은 토질에서는, 접지봉 만을 매설하는 것이나 리드선을 매설하는 것만으로 접지저항을 낮출수가 없어 저감제를 접지봉에 둘러싸는 구조를 채택하고 있으나, 저감제는 무기재료와 전해질을 함유하는 화학저감제와 시멘트, 골재, 탄소섬유를 함유하는 시멘트계 저감제로써 시간이 경과되면 빗물이나 지하수에 의해 유실되어 저감제의 기능이 상실될 뿐만 아니라 토양을 오염시키는 문제점이 발생한다.In soils with high ground resistance and high earth resistance, the earth resistance cannot be lowered by only embedding the ground rod or by laying the lead wire, so that the reducing agent is surrounded by the ground rod. As a cement-based reducing agent containing a reducing agent and cement, aggregate, and carbon fiber, it is lost by rain water or ground water, and the function of the reducing agent is lost, as well as polluting the soil.

본 발명은 상기한 문제점을 해결하기 위해 것으로, 본 발명의 목적은 접지봉과 대지와의 접촉면적을 대폭 확장시켜 접지저항을 감소시키고, 저감제를 효과적으로 함습시킬 수 있는 다수개의 블레이드가 형성된 접지봉을 제공하는 것이다. The present invention is to solve the above problems, an object of the present invention is to greatly expand the contact area between the ground rod and the ground to reduce the ground resistance, to provide a ground rod formed with a plurality of blades that can effectively dampen the reducing agent It is.                         

본 발명은 접지설비에 리드선을 통해 연결되어 일정 깊이의 대지에 매설되는 접지봉에 있어서, 동 또는 동으로 코팅된 원기둥형상으로 일정 직경과 길이를 갖는 접지기둥(12)과, 상기 접지기둥(12)의 측면에 일정 높이와 일정 간격이 되도록 나사상으로 돌출되어 형성된 블레이드(20)로 형성되는 것을 특징으로 한다.The present invention is a grounding rod connected to the grounding equipment is embedded in the ground of a certain depth, the grounding rod 12, having a predetermined diameter and length in the shape of copper or copper coated cylinder, and the grounding pillar 12 It characterized in that formed on the side of the blade 20 is formed to protrude in a screw shape so as to be a predetermined height and a predetermined interval.

본 발명은 다수개 돌출되어 형성된 블레이드(20)에 의해 대지와의 접촉면적을 확장시키고, 상기 각각의 블레이드(20)에 의해 형성되는 블레이드 간극(25)에 일정량의 수분 또는 저감제를 함습하여 대지저항과 접지저항을 효과적으로 감소시키게 된다.The present invention expands the contact area with the earth by the blades 20 formed by a plurality of protrusions, and impregnates a predetermined amount of water or a reducing agent into the blade gaps 25 formed by the respective blades 20. This effectively reduces the resistance and ground resistance.

이하, 첨부된 도면을 참조하여 본 발명의 다수개의 블레이드가 형성된 접지봉을 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a ground rod formed with a plurality of blades of the present invention.

도1은 본 발명의 일실시예에 의한 다수개의 블레이드가 형성된 접지봉의 사시도이고, 도2는 도1의 A-A선의 단면도이다.1 is a perspective view of a ground rod having a plurality of blades according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line A-A of FIG.

본 발명의 바람직한 실시예에 의한 다수개의 블레이드가 형성된 접지봉은 상기 도1 및 도2에 도시된 바와 같이, 동 또는 동으로 코팅된 원기둥형상으로 일정 직경과 길이를 갖는 접지기둥(12)과, 상기 접지기둥(12)의 측면에 일정 높이와 일정 간격이 되도록 나사상으로 돌출되어 형성된 블레이드(20)로 형성된다.Ground rod formed with a plurality of blades according to a preferred embodiment of the present invention, as shown in Figure 1 and 2, the ground column 12 having a predetermined diameter and length in the shape of a copper or copper coated cylinder, and It is formed of a blade 20 protruding in a screw shape to a predetermined height and a predetermined interval on the side of the ground column (12).

또한 상기 접지기둥(12)의 상부는 리드선(40)과 압착 슬리브(30)로 접속된다. 이 때 상기 블레이드(20)는 저감제가 사용되는 경우에 저감제를 모세관현상에 의해 함습하도록 블레이드 간극(25)을 일정하게 형성되는 것이 바람직하다.In addition, the upper portion of the ground pillar 12 is connected to the lead wire 40 and the pressing sleeve 30. At this time, it is preferable that the blade 20 has a constant blade gap 25 so as to impregnate the reducing agent by capillary action when the reducing agent is used.

따라서, 종래의 원기둥형상의 접지봉에 비하여 대지에 접촉되는 면적으로 효과적으로 확대시켜 접지저항을 현저히 줄일 수 있게 된다.Therefore, compared with the conventional cylindrical ground rod, it is possible to effectively enlarge the area in contact with the ground, thereby significantly reducing the ground resistance.

본 발명에 의한 다수개의 블레이드가 형성된 접지봉은 상기 공통접지나 독립접지의 어떠한 형태의 접지방식에도 사용될 수 있으며, 망상접지에 사용되는 경우에도 효과적으로 대지 접촉면적을 확장시키게 된다.Ground rod formed with a plurality of blades according to the present invention can be used in any type of grounding method of the common ground or independent ground, even when used in the network ground effectively expands the ground contact area.

상기와 같은 본 발명에 의한 접지봉을 시공하는 방법은 먼저 시공 위치를 일정 폭과 일정 깊이 이상으로 터를 판다. 이 때 상기 폭은 블레이드(20)의 직경에 따라 상이하게 설정하며, 상기 깊이는 일반적으로 75cm 이상이 되도록 한다. 물론 상기 접지기둥(12)의 직경과 접지기둥에 형성된 동피막의 두께에 따라 상이함은 이미 주지된 기술이다.In the method of constructing the ground rod according to the present invention as described above, first, the construction position is dug a predetermined width and a predetermined depth or more. At this time, the width is set differently according to the diameter of the blade 20, the depth is to be generally 75cm or more. Of course, the difference between the diameter of the ground pillar 12 and the thickness of the copper film formed in the ground pillar is a well known technique.

그 후 본 발명에 의한 접지봉을 타설하고 접지봉과 접지봉은 나동선(Bare copper)를 이용하여 압착 슬리브로 접속한다. 접속된 나동선은 외부의 리드선과 접속하고, 상기 시공위치의 터를 메우고 접지저항을 측정하여 기록하여 시공한다.Thereafter, the ground rod according to the present invention is poured and the ground rod and the ground rod are connected to the crimp sleeve using bare copper. The connected bare copper wire is connected to an external lead wire, and the ground of the construction position is filled, and the ground resistance is measured and recorded.

또한 상기 접지봉을 시공하는 경우에 저감제를 더 삽입시킬 수 있다. 한편 대지중에는 환경조건에 따라 상이하지만 일정량의 수분이 포함되어 있다. 따라서 본 발명에 의한 접지봉에 복수개 형성된 각각의 블레이드(20) 사이인 블레이드 간극(25)상에 모세관현사에 의해 상기 저감제나 수분을 항상 함습하게 된다. 즉 저감제에 의한 유사 접지전극을 확장시키고 지속성을 증대시키게 된다. 또한 저감제를 사용하지 않을 경우에는 블레이드 간극(25) 상에 수분을 함습시켜 대지저항을 낮추고 접지저항을 효과적으로 감소시키게 된다.In addition, when the ground rod is constructed, a reducing agent may be further inserted. On the other hand, the land contains a certain amount of moisture, which varies depending on environmental conditions. Therefore, the capillary projection on the blade gap 25 between the plurality of blades 20 formed in the ground rod according to the present invention always moistens the reducing agent or water. That is, the similar ground electrode by the reducing agent is expanded and the durability is increased. In addition, when the reducing agent is not used, moisture is moistened on the blade gap 25 to lower the earth resistance and effectively reduce the ground resistance.
