Ultra-fast high voltage earthing switch

摘要

ultra fast high voltage uziemnik to reduce the effects of power zwarciowego in rozdzielnicach in case of failure, and the arc current in the switchboard zwarciowego.uziemnik is equipped with a housing (1) in which is mounted a vacuum chamber (2) with pins (3) and a stationary: (4) connected to an electromagnetic drive wiropru0105dowym (6), composed of the electrical coil (9), connected to the system (10) for high power generation mistake frequency and large amplitude.element of a propulsion element is head of eddy current (11), which, in the open position uziemnika is placed near the electric coils (9). a movable contact (4) is connected with the motor (6) via a spring strip breakage (5).to stabilize the position of the movable in the open position is the first block (7), connected in the first performance of the sample at the end of the spring strip breakage (5), connected to the movable element wiropru0105dowym heads (11).in the second example the stability of the movable contact in the open position the first block (7) is connected with stykiem plunger (4), a vacuum chamber (2). in another execution example uziemnik is equipped with additional inertia brake (12).a spring brake (13) is connected with stykiem plunger (4) of the vacuum chamber (2), while the inertia brake (12) is connected with the spring brake (13) loosely, with range size exceeding 2 / 3 jump movable contact (4).in yet another exemplary implementation uziemnik is equipped with additional inertia brake (12) connected with the spring brake (13), and a spring brake (13) is connected with stykiem plunger (4), a vacuum chamber (2) loosely, with range size exceeding 2 / 3 jump contact movable (4).
