CONTACT DEVICE FOR SWITCH VOLTAGE 110, 220 KV

摘要

The invention relates to electrical engineering, namely to the design of contact devices tank-type circuit breaker 110 V and 220 kV. The technical problem of the claimed utility model - to provide a reliable contact force of the main contacts and to reduce "lead-in" resistance when the switch in the device main contact the fixed contact is formed as a truncated cone cut along the generatrix to the sipe having a bent portion and a lead-in chamfer.
