일반적으로 전력 생산시 가스터빈 발전은 가스터빈을 원동기로 사용하여 발전하는 방식으로, 이 가스터빈을 고온, 고압의 연소가스로 터빈을 가동시키도록 되어 있다.In general, gas turbine power generation in power generation is generated by using a gas turbine as a prime mover, and the gas turbine is operated to operate a turbine with high temperature and high pressure combustion gas.

상기 가스터빈을 가동할 때 점화설비를 이용하게 되는데, 이 점화설비는 가스터빈 운전중에 연소방법이 변경될 때 재 점화시키는 설비로서 주요 구성부품으로는 전원 공급부, 점화케이블 및, 점화플러그로 구성되어 있다.An ignition system is used to operate the gas turbine. The ignition system re-ignites when the combustion method is changed during operation of the gas turbine. The main components include a power supply unit, an ignition cable, and an ignition plug. have.

이와 같은 가스터빈의 점화장치는 도 1에 도시된 바와 같이 가스터빈 가동시 공급된 가스를 점화플러그(1)로 점화시키는 역할을 하여 가스터빈 연소실에서 가스가 안정적인 연소를 하도록 도와주는바, 즉 전원 공급부(5)로부터 공급되는 전원이 점화케이블(4)의 케이블(3)을 매개로 인가되어 점화플러그(2)에서 스파크를 일으켜 가스를 점화시킨다.As shown in FIG. 1, the ignition device of the gas turbine serves to ignite the gas supplied when the gas turbine is operated with the spark plug 1, thereby helping to stably burn the gas in the gas turbine combustion chamber. Power supplied from the supply section 5 is applied through the cable 3 of the ignition cable 4 to cause sparks in the spark plug 2 to ignite the gas.

따라서 연소되는 가스의 폭발력을 이용하여 가스터빈의 회전축 동력으로 에너지 변화시키어 발전기를 통해 전력을 생산하게 된다.Therefore, by using the explosive power of the gas to be burned to change the energy to the shaft shaft power of the gas turbine to produce power through the generator.

And the repetition of the stop, these connection portion is the contact force is naturally dropped due to the decrease in the tensile force of the spring, the ignition failure often occurs.

이러한 종래 가스터빈용 점화장치의 점화실패는 결국 전력생산에 차질을 주어 원활한 전력공급을 수행하지 못할 뿐만 아니라, 점화장치의 불시 정지시 복귀 비용도 상당히 소요되는 문제점 등이 있었다.The ignition failure of the conventional ignition device for the gas turbine has a problem in that it does not perform smooth power supply due to the disruption in power production, and also takes a considerable return cost when the ignition device is suddenly stopped.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 가스터빈 내에서 가스를 연소시킬 때 점화플러그의 점화실패를 예방하여 원활한 전력 생산에 기여하면서 점화실패에 의한 가스터빈의 가동 불시정지 등을 예방하는 개선된 가스터빈 점화기의 점화장치 연결구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above conventional problems, and prevents the ignition failure of the spark plug when burning the gas in the gas turbine contributes to the smooth power generation, the uninterrupted operation of the gas turbine by the ignition failure It is an object of the present invention to provide an ignition connection structure of an improved gas turbine igniter that prevents a lamp.

상기와 같은 목적을 달성하기 위한 본 발명은 가스터빈 내에 설치되어 공급된 가스를 점화시키는 로드가 내장된 점화플러그와 이 점화플러그에 연결되는 케이블을 감싼 플렉시블한 튜브외피를 갖춘 점화케이블 및 상기 점화플러그에 전기를 공급하는 전원 공급부로 이루어진 가스터빈의 점화장치에 있어서, 상기 점화플러그의 삽입부와 점화케이블의 커넥터는 나사 체결식으로 접속 연결되고 상기 점화케이블의 전원 공급부 측 접속핀 단자는 전원 공급부의 접속단자와 스냅링을 매개로 연결되어 있다.The present invention for achieving the above object is an ignition cable and a spark plug having a ignition plug with a rod installed in the gas turbine to ignite the supplied gas and a flexible tube jacket wrapped around the cable connected to the ignition plug In the ignition device of the gas turbine comprising a power supply for supplying electricity to the power supply, the inserting portion of the spark plug and the connector of the ignition cable is connected to the screw connection type and the connecting pin terminal of the power supply side of the ignition cable is the power supply portion It is connected by connecting terminal and snap ring.
