Common Kilovac High Voltage Relay Designs
Hinged Armature Design
This traditional design approach provides high mechanical reliability and is adaptable to a number of contact configurations. The contact is actuated by the movement of the spring-loaded armature when the coil is energized. The coil assembly is external to the vacuum package and readily replaceable.
Diaphragm Design
This simple, low-cost design approach makes use of a thin molybdenum diaphragm which allows contact movement to be transferred into the vacuum package from the external motor assembly. This basic design is used in a large number of Kilovac products.
Solenoid Design
When high current loads must be interrupted, the solenoid design provides the force necessary to separate large contacts quickly. It also provides high contact holding force to keep contact resistance low. These attributes make this design the choice for high current DC load switching relays and contactors.
