Benefits of technology

[0007]The following discussion discloses and describes a switch assembly including a switch and a high impedance element used for energy harvesting purposes that are connected to a power line at one end and assembly electronics at an opposite end, where in one non-limiting embodiment the switch assembly has particular application for use in connection with a vacuum interrupter. The high impedance element has higher impedanc

Problems solved by technology

However, both of these types of devices have significant size and weight in order to provide the necessary power to actuate the vacuum interrupter contacts.
For example, current transformers are typically large and bulky because the

Example

[0013]The following discussion of the embodiments of the disclosure directed to a switch assembly including a switch and a high impedance element used for energy harvesting purposes that are connected to a power line at one end and assembly electronics at an opposite end is merely exemplary in nature, and is in no way intended to limit the disclosure or its applications or uses. For example, the discussion herein refers to the switch assembly as being part of a fault recloser switch having a vacuum interrupter. However, as will be appreciated by those skilled in the art, the switch assembly will have other applications.

Abstract

A switch assembly including a switch and a high impedance element used for energy harvesting purposes that are connected to a power line at one end and assembly electronics at an opposite end, where in one non-limiting embodiment the switch assembly has particular application for use in connection with a vacuum interrupter. The high impedance element has higher impedance than the switch so that current flows through the switch from the power line when the switch is closed and through the high impedance element from the power line when the switch is open, where power from the high impedance element can power a switch closing device, such as a solenoid actuator. The high impedance element can be a resistive element, a capacitive element or a combination of a resistive and capacitive element.
