Industry Background

Solution Overview

The magnetic induction double-confirmation device mainly consists of a magnetic induction sensor and a receiving device. The magnetic induction sensor uses a non-contact induction principle to detect the status of the disconnector and transmit the status information to the receiving device. The receiving device is installed in the control cabinet, terminal box, or independent cabinet, achieving logical calculation and status output of the disconnector status signal. The magnetic induction double-confirmation device features safe and reliable non-contact detection, easy installation, and suitability for various equipment types and operating environments. It accurately identifies the open/close status of disconnectors, providing a more secure and reliable technical guarantee for one-click sequence control.
