Title: METHOD FOR PREVENTING ARCING BETWEEN CONTACTS OF SWITCHING EQUIPMENT
Abstract:
A method for preventing arcing between contacts of switching equipment requires the use of an additional switching device. The additional switching device has switching contacts and switches a protective circuit. The protective circuit consists of, connected in-parallel, a capacitor, a voltage protection device and a discharge circuit to be switched. The connection and disconnection of the protection circuit, in-parallel to the switching equipment contacts to be protected, is carried out in a strict sequence. In order to enhance protection effectiveness, an inductance is introduced into load circuits.
