Device for measuring electrical current and method of manufacturing the same

摘要

Disclosed herein are embodiments of devices for measuring electrical current and related systems and methods for forming and using such devices. According to certain embodiments, devices according to the present disclosure may comprise Rogowski coils. Also disclosed are systems and methods for forming a current measuring device using a bobbin that may allow for the use of a continuous length of wire for all windings associated with the current measuring device. Automated manufacturing techniques may be utilized to facilitate the manufacture of devices for measuring electrical current and/or may reduce the cost of such devices. Various embodiments disclosed herein include the use of a bobbin that may be selectively configured between a linear configuration and a closed configuration. One or more current sensors disclosed herein may be utilized in connection with a motor management relay or other type of intelligent electronic device.

主权项

1. A current sensor, comprising:
a continuous length of wire; and a one-piece folding bobbin, comprising:
a first end;a second end;a plurality of winding sections formed in the one-piece folding bobbin, configured to be wound with the continuous length of wire;a plurality of living hinges formed in the one-piece folding bobbin and flexibly linking each winding section to its adjacent winding section of the plurality of winding sections and configured to allow the one-piece folding bobbin to transition between a linear configuration and a closed configuration; wherein the first end and the second end of the one-piece folding bobbin are selectively arranged in proximity to reconfigure the one-piece folding bobbin from the linear configuration to the closed configuration.
