乐山HX-FDR series switch controller

The HX-FDR series intelligent controller is a classic intelligent control terminal launched by our company and has been widely used in power distribution projects across various regions. Installed at the responsibility demarcation points of overhead power distribution lines, the product works in conjunction with demarcation circuit breakers and other equipment to provide branch line protection. It can automatically cut off faults such as phase-to-ground faults, phase-to-phase short circuits, and overcurrents on the line, ensuring the power safety of non-faulty users. It collects real-time data from four analog signals: three-phase current and zero-sequence current; with a liquid crystal display interface and key input, human-machine operation is simple and quick; using a 32-bit ARM high-speed single-chip microcomputer as the main control chip, it boasts fast operation speed, sensitive and accurate detection, and timely and rapid protection action. The product has local/remote switching functions and offers selectable communication methods including local serial port parameter setting, GSM SMS control, and GPRS wireless communication, making it widely applicable to the control and protection of 10KV~66KV overhead power distribution lines in urban and rural areas.

Product Description

Product Overview

The HX-FDR series intelligent controller is a classic intelligent control terminal launched by our company and has been widely used in power distribution projects across various regions. Installed at the responsibility boundary points of overhead power distribution lines, it works with boundary circuit breakers and other equipment to protect branch lines. It can automatically cut off phase-to-ground faults, phase-to-phase short circuits, overcurrents, and other faults on the line, ensuring the safe power supply for non-faulty users. It collects real-time data of three-phase current and zero-sequence current (four analog signals); with a liquid crystal display interface and key input, human-machine operation is simple and fast; it uses a 32-bit ARM high-speed single-chip microcomputer as the main control chip, with fast running speed, sensitive and accurate detection, and timely and rapid protection action. The product has local/remote switching functions and offers selectable communication methods including local serial port parameter setting, GSM SMS control, and GPRS wireless communication, making it widely applicable to the control and protection of 10KV~66KV overhead power distribution lines in urban and rural areas.
