Description
본 고안은 송.변전설비 휴전작업시 작업자의 안전을 위하여 해당 전력 설비를 접지선으로 접지시키 위한 접지봉의 연결구조에 관한 것으로서, 특히 길이조절이 가능한 길이조절을 위한 연결구조에서 볼트와 너트의 조립구조를 개선하여 길이조절을 위한 연결부위의 내구성이 향상되는 접지봉의 연결구조에 괸한 것이다.The present invention relates to the connection structure of the ground rod for grounding the power equipment with a ground wire for the safety of the worker during the truce work of transmission and substation facilities, in particular the assembly structure of the bolt and nut in the connection structure for adjustable length It is better to improve the connection structure of the ground rod to improve the durability of the connection part for adjusting the length.
일반적으로 접지봉은 사용 전압별로 가감 연결조립하여 변전소근무자가 접지봉을 이용하여 접지선을 들여올려 접지선 코넥타 나사를 조여 대지에 접지하고 반대로 접지선을 제거하는데 사용하는 절연기구로서 감전사고의 예방을 그 기능으로 하고 있다.In general, the ground rod is an insulated device used by substation workers to lift the ground wire using the ground rod and tighten the ground wire connector screw to ground the earth, and to remove the ground wire. Doing.
이러한 기능을 갖는 종래의 접지봉은 길이 조정을 위한 연결구조가 취약하여 틀림과 같은 변형이 발생하는 문제점이 있었다.In the conventional ground rod having such a function, there is a problem in that deformation such as a mistake occurs due to a weak connection structure for adjusting the length.
즉,도1에서 종래의 접지봉 연결구조는 절연봉(2)들의 양측에 끼워지는 연결구 (10)(20)중 어느 한측의 연결구(10)에 암나사부를 갖는 홈을 형성하고, 다른측 연결구에 홈에 진입하는 돌기(14)의 외주연에 수나사부를 형성하여 1차 나사식으로 조립하고, 다른측의 외주연(12)에 나사부를 형성하여 두개의 연결구(10)(20)를 너트(30)로 체결하는 구조에 의해 전체적으로 나사식 체결을 이루고 이에 결속상태를 의존함으로서, 나사부들의 마모가 발생하는 경우 접지봉의 견고한 결속이 어려운 문제점이 있었다.That is, in FIG. 1, the conventional ground rod connecting structure forms a groove having a female screw portion in the connector 10 of any one of the connectors 10 and 20 fitted to both sides of the insulating rods 2, and the groove in the other connector. A male screw is formed on the outer circumference of the protrusion 14 entering the main body and assembled by a first screw type, and a thread is formed on the outer circumferential edge 12 on the other side to connect the two connectors 10 and 20 to the nut 30. By making a screw-type fastening entirely by the structure to be fastened by the structure and depending on the binding state, there is a problem that the solid binding of the ground rod is difficult when the wear of the screw portion occurs.
본 고안은 송.변전설비 휴전작업시 작업자의 안전을 위하여 해당 전력 설비를 접지선으로 접지시키 위한 접지봉에서 길이조절을 위한 연결구조에서 볼트와 너트의 조립구조를 개선하여 길이 조절을 위한 연결부위의 내구성이 향상되는 접지봉의 연결구조를 제공하는 데 있다.The present invention improves the assembly structure of bolts and nuts in the connection structure for adjusting the length of the ground rod for grounding the power equipment with the ground wire for safety of workers during the truce work of transmission and substation facilities. It is to provide an improved structure of the ground rods.
