Description

지상 배전설비의 콘크리트 기초대 및 이의 설치방법Concrete foundation of ground distribution system and its installation method
본 발명은 지상 배전설비의 콘크리트 기초대 및 이의 설치방법에 관한 것으로, 더욱 상세하게는 지진에 의한 배전설비와 기초대의 구조적 안전성은 확보하면서 유지보수를 위한 분리와 설치가 용이한 지상 배전설비의 콘크리트 기초대 및 이의 설치방법에 관한 것이다.The present invention relates to a concrete foundation base of the ground distribution equipment and its installation method, and more particularly, concrete of the ground distribution equipment easy to separate and install for maintenance while ensuring the structural safety of the distribution equipment and foundation by the earthquake It relates to a foundation and its installation method.
최근 전 세계에서 지진으로 인한 전력설비의 피해가 빈번하게 발생하고 있으며, 이로 인한 전력공급 중단은 국민 및 산업계의 피해로 직결되므로 내진설계의 중요성이 대두되고 있는 실정이다.In recent years, the damage of electric power facilities due to earthquakes has occurred frequently around the world, and the interruption of electric power supply is directly connected to the damage of the people and industry, so the importance of earthquake-resistant design is emerging.
송전, 배전 및 변전설비는 2009년부터 지진재해대책법에 따라 법적 요건으로서 내진설계가 의무화되어 있으며, 이에 따라 당사에서는 2003년부터 송배전설비 내진설계 실무지침서를 제정하여 운영하고 있다.Since 2009, seismic design is mandatory as a legal requirement under the Earthquake Disaster Countermeasures Act. As a result, the company has been operating seismic design guidelines for transmission and distribution facilities since 2003.
따라서, 송전, 배전 및 변전설비들은 당사의 송배전설비 내진설계 실무지침서에서 요구하는 0.154g(규모 6.3)(g는 중력가속도) 이상의 내진성능을 만족하도록 설계되어야 한다. Therefore, power transmission, distribution and substation facilities should be designed to meet the seismic performance of 0.154g (scale 6.3) (g is gravitational acceleration) required by the company's seismic design guidelines.
당사에서는 현재 약 10만 여대의 지상 배전설비(도 1 참조)가 운영되고 있으나, 현재 운영중인 대부분의 지상 배전설비들은 콘크리트 기초대에 안정적으로 고정하기 위한 앵커볼트의 시공상태가 미흡하거나 설치되어 있지 않아 지진에 매우 취약한 상황이다(도 2 참조).At present, about 100,000 ground distribution facilities (see Fig. 1) are in operation, but most of the ground distribution facilities currently in operation are not installed or installed with anchor bolts for fixing them stably on concrete foundations. It is not very vulnerable to earthquakes (see Figure 2).
또한, 도 3 내지 도 5에 도시된 바와 같이, 콘크리트 기초대(3)는 시공 편의성을 고려하여 콘크리트를 2단(3a,3b)으로 구분하여 시공하고 있으며, 2단으로 구분된 콘크리트 기초대(3)는 접합부를 접착제(4)와 일부 사다리꼴 형태의 홈(5a,5b)으로 구성하여 일체화시키고 있다. 그러나 상하 기초대의 접합부가 접착제로 연결되도록 시공되므로 지진시 분리되어 지진피해를 입을 가능성이 높다.In addition, as shown in Figures 3 to 5, the concrete foundation (3) is divided into two stages (3a, 3b) for the construction in consideration of construction convenience, and divided into two stages of concrete foundation ( 3) the bonding part consists of the adhesive agent 4 and the some trapezoidal groove | channel 5a, 5b, and is integrated. However, since the joints of the upper and lower foundations are constructed to be connected with an adhesive, there is a high possibility that they will be separated during an earthquake and suffer earthquake damage.
도 6에 도시된 바와 같이, 대표적인 20대의 지상 배전설비의 내진성능평가 결과 19대의 배전설비가 내진성능이 부족한 것으로 나타났다. 그리고 상하 기초대의 접합부에 대한 내진성능을 확인하기 위하여 수치해석을 수행한 결과, 도 7에 도시된 바와 같이, 지진시 발생되는 수평하중에 대하여 접합부의 전단내력이 부족한 것으로 나타났다.As shown in FIG. 6, the seismic performance evaluation results of the representative 20 ground distribution facilities showed that the 19 distribution facilities lacked the seismic performance. Numerical analysis was performed to confirm the seismic performance of the joints of the upper and lower foundations, and as shown in FIG. 7, the shear strength of the joints was insufficient for the horizontal load generated during the earthquake.
따라서, 지진 발생시 안정적 전력공급을 위해서는 지상 배전설비의 콘크리트 기초대의 체계적인 내진설계 적용이 필요한 상황이다.Therefore, in order to provide stable power in the event of an earthquake, it is necessary to apply a systematic seismic design of the concrete foundation of the ground distribution system.
한편, 도 3 내지 도 5에 도시된 지상 배전설비 콘크리트 기초대는 안정적인 고정을 위해 앵커볼트로 시공하면 배전설비의 유지보수나, 용량 증설로 인한 교체시 배전설비 내 여유공간 부족으로 인한 앵크볼트의 제거나 설비의 인양 등이 용이하지 않다. 특히, 10만 여대의 지상 배전설비들은 대부분 10년 이상 운영되고 있는 것들로서 열화된 것이 많아 향후 유지보수 및 교체가 지속적으로 이루어져야 하므로 지상 배전설비의 콘크리트 기초대의 내진설계 적용이 필요한 상황이다.Meanwhile, when the ground distribution equipment concrete foundation shown in FIGS. 3 to 5 is constructed with anchor bolts for stable fixing, the anchor bolts may be removed due to lack of free space in the distribution equipment during maintenance of the distribution equipment or replacement due to capacity expansion. Or lifting of equipment is not easy. In particular, about 100,000 ground distribution equipments have been in operation for more than 10 years, and many of them are deteriorated. Therefore, maintenance and replacement must be continued in the future, so it is necessary to apply the seismic design of the concrete foundation of the ground distribution equipment.
