HIGH-SPEED CLOSING SWITCH IN POWER DISTRIBUTOR |
摘要 |
A high speed closing switch in a power distributor includes: a case forming an external appearance; a first electrode provided within the case and including a through hole; a second electrode having a receiving recess facing the through hole; a moving contact point member having a cylindrical portion received in the through hole so as to be put into the receiving recess and a flange portion formed at one end of the cylindrical portion; and a closing coil wound on a base of the case, wherein a damping hole is formed at receiving recess of the second electrode. When the moving contact point member put into the receiving recess approaches its final position, a damping force is applied to the moving contact point member to stably and accurately control the final position.
