A rigid bar transition device for a high speed electric railroad is disclosed. The rigid bar transition device for a high speed electric railroad according to the present invention can improve the structural stability of the transition device by corresponding to the tendency of the high speed electric railroad and maximally maintaining the speed of the electric railroad by reducing stress applied to a catenary line by gradually changing the stiffness or elasticity of the catenary line and a rigid bar. Also, the stiffness or elasticity change rate of the transition device is reduced and a sagging amount is reduced in an installation process. A separation margin can be increased by insulating a resonance frequency of the transition device from a passing frequency of the electric railroad.
고속용 강체전차선 이행장치가 개시된다. 본 발명에 따른 고속용 강체전차선 이행장치에 의하면, 전기철도의 고속화 추세에 대응하여 이행장치의 구조적 안정성을 향상시킬 수 있고, 현수전차선과 강체전차선의 강성 또는 탄성을 점진적으로 변화시킴으로써 전차선에 가해지는 응력을 완화시키는 역할을 하여 열차의 속도를 최대한 유지시킬 수 있다. 또한, 이행장치의 강성이나 탄성 변화율이 작게 하고, 설치시 처짐량이 작도록 구현할 수 있으며, 열차의 통과주파수(Passing Frequency)와 이행장치의 공진주파수를 서로 절연시켜 분리 마진을 높일 수 있다.
