Fault indicator fault indicator panel type EKL4

Overview EKL3. EKL-4 panel type fault indicator is supporting the installation of the power distribution network system ring network cabinets, cable branch box, the box changes, for short circuit and single-phase fault indication corresponding to a cable segment realtime monitoring devices. When the line fails, the staff can make use of indicator alarm indicator, quickly determine the fault zone, and find the point of failure. Meanwhile, real-time alarm information can be sent to the monitoring center server, showing regional and specific location of the fault in the computer's monitor screen, the guide line patrol officers to quickly identify the fault zone and find the point of failure. The indicator for solving troubleshooting issue provides the best way. To improve work efficiency, reduce outage time, the rapid restoration of electricity, improve reliability and economic efficiency, has great significance. Main Functions 1. Short circuit alarm indication: Short circuit sensor detection in the work of the current line, when the line short-circuit fault and the fault current reaches or exceeds the alarm current setting value, short-circuit sensor alarm signal transmitted through the optical fiber to the host, the host receives After this signal, it generates a corresponding alarm indication signal. 2. grounding alarm indication: ground sensors work in zero sequence current detection circuit, when the line ground fault occurs and the ground fault current reaches or exceeds the alarm current setting, the ground sensor alarm signal, fiber optic transmission to the host, the host receives After this signal, a corresponding alarm indication signal. 3. Auto reset: When the indicator alarm signal, if there is no manual reset, the indicator will automatically reset the set reset time. 4. Manual reset: When an alarm indicator, can be reset by the "Reset / Test" button on the trigger indicator host panel, in order to disarm the alarm. 5. Test: performance indicator can be a self-test. Test by pressing the Host "Reset / Test" button on the panel and held 1.5 seconds. 6. Intelligent: After the alarm indicator generates an indication signal, alarm signal output can be remote. Also receive remote reset signal, the indicator for remote reset operation.
