Abstract

PURPOSE: A ground transformer case is provided to replace a case in a short time by separating the case from a ground transformer main body when the case is damaged. CONSTITUTION: A ground transformer main body(1) is detachably mounted to a case. The case and the ground transformer main body are settled at a stationary stand by using a coupling bolt. A charge unit protective stand(4) is installed at both sides of the ground transformer main body. A guide cylinder(5) movably operates the charge unit protective stand. A joint nut(6) moves and fixes the charge unit protective stand. The joint nut is fixed to a joint nut screw line when a separation preventing terminal contacts with the guide cylinder.

Description

무정전 이설교체가 가능한 지상변압기 외함{Outer housing for transformer}Uninterruptible ground transformer enclosure {Outer housing for transformer}

본 발명은 지상변압기 외함에 관한 것으로, 특히 외함 손상시 지상변압기의 정전수반 없이 외함을 교체하여 시공할 수 있는 무정전 이설교체가 가능한 지상변압기 외함에 관한 것이다.The present invention relates to a ground transformer enclosure, and more particularly, to a ground transformer enclosure capable of replacing an uninterruptible relocation, which can be installed by replacing the enclosure without the power failure of the ground transformer.

일반적으로 지상변압기와 이를 보호하는 외함 함체는 일체형으로 되어 있는바, 이에 따라 외함과 일체로 이루어진 지상변압기에서 외함이 손상되고 지상변압기 본체가 손상이 없을시 에도 일체형 지상변압기 특성상 전량 교체해야만 하는데, 이때의 문제점은 첫째, 지상변압기는 교체시 사선작업으로 진행되므로 정전수반이 불가피함에 따라 수요체의 정전협의와 안내 등의 시간적 낭비요소가 내재되어 있고, 둘째, 지상변압기 교체시 주로 전기사용량이 적은 이른 새벽 시간대에 교체작업을 위하여는 고압단자와 저압단자를 각각 분리해야만 하는 작업의 번거로움이 있으며, 셋째, 분리된 고압단자(엘보)에 미세먼지와 같은 이물질 침투에 의한 절연파괴 등이 야기되는 문제점 등이 있었다.In general, the ground transformer and the enclosure that protects it are integrated. Therefore, even when the ground transformer is integrated with the enclosure, even if the enclosure is damaged and the ground transformer body is intact, all ground transformers must be replaced. First of all, the ground transformers are inclined by replacement work. Therefore, due to the necessity of power failure, there is an inherent waste of time such as discussion and guidance of power outages. For the replacement work in the early morning hours, it is troublesome to separate the high voltage terminal and the low voltage terminal. Third, the problem of insulation breakdown caused by the infiltration of foreign substances such as fine dust into the separated high voltage terminal (elbow). There was a back.

또한, 종래에는 외함 일체형 지상변압기 교체에 막대한 공사비와 자원이 낭비되는 문제점도 지니고 있었다.In addition, there was also a problem in that a huge construction cost and resources are wasted in the replacement of the enclosure integrated ground transformer.

이에 본 발명은 상기와 같은 종래 문제점을 감안하여 발명된 것으로, 외함 손상시 지상변압기 본체와 외함을 분리시켜 이 외함만을 교체함에 따라 외함 교체가 단시간 내에 용이하게 이루어지고 경제적 측면도 개선되는 무정전 이설교체가 가능한 지상변압기 외함을 제공함에 그 목적이 있다.Therefore, the present invention was invented in view of the conventional problems as described above. When the enclosure is damaged, the ground transformer main body and the enclosure are separated, thereby replacing only the enclosure. The purpose is to provide a possible ground transformer enclosure.

상기와 같은 목적을 달성하기 위한 본 발명은 지상변압기 본체를 보호하기 위해 이 지상변압기 본체의 외부를 감싸는 지상변압기 외함에 있어서, 상기 외함에 지상변압기 본체가 분리하여 장착되되, 이 외함과 지상변압기 본체가 안착되는 고정 받침대와, 상기 지상변압기 본체의 양측 측면에 설치되는 충전부 보호대, 상기 충전부 보호대를 이동 가능하게 작동시키는 가이드 실린더, 상기 충전부 보호대를 이동 및 고정시키는 조임너트와 이탈방지 단자 및 조임너트 나사선을 구비하여 이루어진 구조로 되어 있다.The present invention for achieving the above object is in the ground transformer enclosure surrounding the outside of the ground transformer body to protect the ground transformer body, the ground transformer body is mounted separately in the enclosure, the enclosure and the ground transformer body Fixed seats on which the seats are mounted, charging part guards installed on both sides of the ground transformer main body, guide cylinders for movably operating the charging part guards, tightening nuts for moving and fixing the charging part guards, and preventing release terminals and tightening nut threads. It has a structure consisting of.

상기와 같은 본 발명에 따른 무정전 이설교체가 가능한 지상변압기 외함은 종래의 문제점으로 지적된 일체형을 지상변압기 본체와 외함으로 분리시켜 각기 교체가 가능토록 개발되었으며, 특히 외함 교체시는 무정전 교체가 가능토록 구성된 지상변압기 본체의 충전부 보호대가 특징으로 적용되고, 이 충전부 보호대는 외함 교체시 크레인과 외함의 수평각도 맞질 않아 발생되는 흔들림에 충전부 보호역할을 수행하여 무정전 외함 교체가 가능하고 작업 중 발생할 수 있는 고장정전 및 안전사고 예방이 가능하다.The above-described ground transformer enclosures capable of replacing the uninterrupted relocation according to the present invention have been developed so that each can be replaced by separating the one-piece type that is pointed out as a conventional problem into the ground transformer body and the enclosure. The charging part guard of the ground transformer main body is applied, and this charging part guard performs the charging part protection role against the shaking caused by the horizontal angle between the crane and the enclosure when replacing the enclosure. Power failures and safety accidents can be prevented.

이하, 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 지상변압기 본체(1)를 외부에서 감싸아 보호하는 외함(2)의 손상시 이 외함(2)만을 교체 시공할 수 있는 무정전 이설 교체가 가능한 지상변압기 외함이다.The present invention is a ground transformer enclosure that can be replaced by an uninterrupted relocation that can be replaced only when the outer case 2 is damaged when the outer transformer body 1 is wrapped and protected from the outside.

본 발명은 지상변압기 본체(1)를 외부에서 감싸아 보호하는 지상변압기 외함에 있어서, 상기 외함(2)에 지상변압기 본체(1)가 분리하여 장착되되, 이 외함(2)과 지상변압기 본체(1)가 안착되는 고정 받침대(3)와, 상기 지상변압기 본체(1)의 양측 측면에 설치되는 충전부 보호대(4), 상기 충전부 보호대(4)를 이동 가능하게 작동시키는 가이드 실린더(5), 상기 충전부 보호대(4)를 이동 및 고정시키는 조임너트(6)와, 이탈방지단자(7) 및 조임너트 나사선(8)으로 이루어진 구조로 되어 있다.In the present invention, the ground transformer main body (1) in the ground transformer enclosure to wrap and protect the outside, the ground transformer main body (1) is detachably mounted to the enclosure (2), the enclosure (2) and the ground transformer main body ( 1) a fixed pedestal (3) to be seated, a charging unit guard (4) installed on both sides of the ground transformer body (1), a guide cylinder (5) for movably operating the charging unit guard (4), the The fastening nut 6 which moves and fixes the live part guard 4, and the escape prevention terminal 7 and the fastening nut screw 8 are comprised.

그리고 상기 외함(2)과 고정 받침대(3)는 체결용 볼트(9)들로 손쉽게 고정 및 분리시킬 수 있고, 상기 지상변압기 본체(1)와 외함(2) 양측면 상부에는 이동용 고리(10)가 각각 설치되어 있다.And the enclosure (2) and the fixing pedestal (3) can be easily fixed and separated by fastening bolts (9), the ground transformer body (1) and the upper side of the enclosure (2) on both sides of the moving ring (10) Each is installed.

또한, 상기 고정 받침대(3)에 지상변압기 본체(1)와 외함(2)을 구분지어 장착할 수 있도록 되어 있는바, 이에 따라 본 발명은 상기 고정 받침대(3)를 기반으로 하여 지상변압기 본체(1)를 설치하고 외함(2)을 이 고정 받침대(3) 위에 안착 후 체결용 볼트(9)들을 체결하여 설치할 수 있다.In addition, the ground transformer body (1) and the enclosure (2) is to be mounted separately to the fixed pedestal (3), according to the present invention based on the fixed pedestal (3) the ground transformer body ( 1) can be installed and the enclosure (2) is seated on the fixing pedestal (3) and can be installed by fastening the fastening bolts (9).

한편, 상기 외부 함체인 외함(2) 손상시 이 외함(12)을 교체 시공할 때 먼저 이 외함(2)의 여러 곳에 있는 체결용 볼트(9)들을 풀고 외함(2)의 이동용 고리(10)를 이용하여 손쉽게 철거할 수 있으며, 특히 외함(2) 철거시 상기 지상 변압기 본체(1)에 부착된 충전부 보호대(4)를 가이드 실린더(5)를 통하여 도 4의 화살표 (가)방향으로 안에서 밖으로 이동시키고, 이탈방지단자(7)가 가이드 실린더(5)에 접하면 조임너트(6)를 조임너트 나사선(8)에 고정시키고 난 후, 상기 외함(2)을 교체하기 위해 공지의 크레인으로 이 외함(2)을 들어올릴 때 발생하는 흔들림에도 지상변압기 본체(1)의 특고압과 저압에 충전부가 보호되므로 무정전 교체가 가능하도록 되어 있다.On the other hand, when replacing the outer case (12) when the outer case of the outer case (2) is damaged when the fastening bolts (9) in the various places of the outer case (2) first to move the ring 10 of the outer case (2) Can be easily dismantled, and in particular, when the enclosure (2) is dismantled, the charging part protector (4) attached to the ground transformer body (1) is moved outward in the direction of arrow (a) of FIG. 4 through the guide cylinder (5). When the separation prevention terminal 7 comes into contact with the guide cylinder 5, the tightening nut 6 is fixed to the tightening nut screw thread 8, and then a known crane is used to replace the enclosure 2. The uninterruptible replacement is possible because the charging part is protected against the special high pressure and low pressure of the ground transformer body 1 even when the shaking occurs when lifting the enclosure 2.

그리고 평상시에는 상기 충전부 보호대(4)를 화살표 (나) 방향으로 이동시켜 지상변압기 본체(1)의 안쪽으로 이동시킨 후 조임너트(6)와 조임너트 나사선(8)을 이용하여 고정시키면, 충전부 보호대(4)가 안쪽으로 밀려 들어가 작업을 보다 용이하게 해주도록 되어 있다.In addition, if the moving part protector 4 is moved in the direction of the arrow (b) to the inside of the ground transformer main body 1 and then fixed by using the tightening nut 6 and the tightening nut screw 8, the charging part protector (4) is pushed inward to make the work easier.
