본 발명은 복합화력 발전기의 본체 케이싱 내부 충진된 냉각용 수소가스의 외부 누설을 방지하는 발전기 케이싱의 가스누설 방지구조에 관한 것이다.The present invention relates to a gas leakage preventing structure of the generator casing to prevent the external leakage of the hydrogen gas for cooling filled inside the main body casing of the combined cycle power generator.

공지된 바와 같이 복합화력 발전기는 수소냉각 동기 발전기를 이용하여 매일 발전기의 기동, 정지를 반복하는 운전을 수행하고 있으며, 이러한 운전은 발전기의 운전피로, 예를 들어 열화, 진동, 수축, 팽창 등이 가중되고 있는 실정이다.As is well known, the combined cycle power generator uses a hydrogen-cooled synchronous generator to perform the operation of repeatedly starting and stopping the generator every day. It is being aggravated.

한편, 발전기 냉각용 수소가스는 정상 운전시 발전기 케이싱 내부에서 수소 순도 98%이상, 수소압력 30Psig를 유지하여 운전하도록 되어 있으며, 이러한 냉각용 수소가스의 정상 순도를 유지하기 위한 공기 및 밀봉 유혼합가스 강제 배출량을 통상 1일 기준 수소 1~1.5병(약 300ft3/일) 정도이고, 이에 해당하는 수소량을 보충하면서 운전하고 있다.On the other hand, the generator cooling hydrogen gas is operated to maintain a purity of more than 98% hydrogen, hydrogen pressure 30Psig in the generator casing during normal operation, air and sealed mixed gas to maintain the normal purity of the cooling hydrogen gas Forced emissions are usually about 1 to 1.5 bottles of hydrogen (about 300 ft 3 / day) per day, and are operating while replenishing the corresponding amount of hydrogen.

그러나 일일 기동, 정지를 반복하는 발전기 운전피로에 의한 발전기 냉각용 수소가스의 누설 사례를 빈번하게 발생하여 발전기 정지로 인한 전력손실, 수소가스 누출에 의한 안전사고 내재, 수소가스 사용량 증가 및, 정비비용의 증가 등을 유발시키고 있었다.However, there are frequent cases of leakage of hydrogen gas for generator cooling due to generator fatigue which starts and stops every day, causing power loss due to generator shutdown, inherent safety accidents due to hydrogen gas leakage, increased hydrogen gas usage, and maintenance cost. Was causing an increase.

즉 종래 발전기 케이싱에서 수소가스 누설과정을 설명하면, 발전기 케이싱의 선단 브라켓트(End bracket) 상하 접합면이 면접촉 조립후 밀봉홀에 밀봉재를 주입하여 발전기 케이싱의 내부 기밀을 유지하나, 발전기 운전시 잦은 기동, 정지로 인한 본체 케이싱의 수축 팽창으로 밀봉재가 외부로 흘러 나와 발전기 케이싱의 기밀이 훼손되어 냉각용 수소가스가 외부로 누설되는 문제점이 제기되어 왔다.In other words, when explaining the leakage process of hydrogen gas in the conventional generator casing, the upper and lower joining surfaces of the end brackets of the generator casing maintain the airtightness of the generator casing by injecting a sealing material into the sealing hole after surface contact assembly. The shrinkage and expansion of the main body casing due to the start and stop has caused a problem that the sealing material flows to the outside, which damages the airtightness of the generator casing and leaks cooling hydrogen gas to the outside.

또한 진동, 수축, 팽창의 영향으로 일정기간 경과 후 이 선단 브라켓트의 상하 접합면과 접합면 코너에서 이들 접합면에 도포한 밀봉재가 외부로 밀리면서 수소가스가 누설되는 문제점도 있었다.In addition, due to the effects of vibration, shrinkage, and expansion, hydrogen gas leaks as the sealant applied to these joint surfaces is pushed outward from the upper and lower joint surfaces and the joint surface corners of the tip bracket after a certain period of time.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 발전기 본체 케이싱의 밀봉구조를 개선하여 냉각용 수소가스의 누설을 방지함에 따라 발전기 설비의 신뢰도 향상은 물론, 발전 손실과 안전사고를 미연에 예방할 수 있는 발전기 케이싱의 가스누설 방지구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, by improving the sealing structure of the generator body casing to prevent leakage of the cooling hydrogen gas, as well as improving the reliability of the generator equipment, power loss and safety accidents The purpose is to provide a gas leakage preventing structure of the generator casing that can be prevented in advance.
