Abstract
A compact vacuum interrupter has an insulator element, a moving contact connection, a fixed contact connection, a moving contact, and a fixed contact. The moving contact has a moving contact rod and a moving-contact contact element. The fixed contact has a fixed contact rod and a fixed-contact contact element. The moving contact is formed with a material that is mechanically stronger than a material of the fixed contact.
Claims14
A compact vacuum interrupter, comprising:
- an insulator element, a movable-contact connection, a movable contact, a fixed-contact connection, and a fixed contact;
- said movable contact having a movable-contact rod and a movable-contact contact element;
- said fixed contact having a fixed-contact rod and a fixed-contact contact element;
- said movable contact being formed with a first material and said fixed contact being formed with a second material, wherein said first material is mechanically stronger than said second material;
- said movable-contact rod having a given diameter and being formed with a narrowing, in a first movable-contact rod region, with said narrowing having a reduced diameter reducing the given diameter of said movable-contact rod by 5% to 25%.
