Description: I. Introduction WHL-6 type charging and fault monitoring comprehensive indicator is supporting the installation of the power distribution network system ring network, cable branch box, the box changes to indicate the charging status of the corresponding cable and the corresponding cable short circuit and single phase of a real-time fault monitoring device segment. When the live line or failure, the staff can make use of indicator alarm indicator, to quickly determine whether the line is currently live and fault zones, and find the point of failure. At the same time, the alarm information can be sent in real time to a server monitoring center, showing the specific location of the fault area and in the monitoring of the computer screen, the guide line patrol officers to quickly identify the fault zone and identify trouble spots. The indicator for troubleshooting provides the best way to find the problem. To improve work efficiency, reduce outage time, the rapid restoration of electricity, improve reliability and economic efficiency, has great significance. Second, the main features: 1, short circuit fault indication: by short-circuit sensor circuit current, when the line short-circuit fault current reaches or exceeds the setting value of the short-circuit fault alarm current, short-circuit sensor alarm signal, optical fiber transmission to the host, the host After receiving this signal, 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, ground sensor alarm signal, fiber optic transmission to the host, the host receives This signal, generating a corresponding alarm indication signal. 3, high-pressure live instruction: Indicators on-line monitoring of high voltage lines charged situation. Through the host on the front panel "L1, L2, L3 phase" corresponding high-brightness LED flash indicating a way that reflects the line is charged; while addressing the traditional live indicator indicates low brightness shortcomings. LED flash frequency by speed can be roughly divided line voltage or line voltage changes. LED operating voltage source for high voltage electric field to take power, do not use the host battery power, so that the accuracy and directions indicated improved live life in the true sense. 3, high-pressure nuclear phase: on the front panel by high-pressure nuclear phase-hole test and verify the accuracy of the input signal and the high-pressure high-voltage electric fault indication. In order to differentiate and confirm the high-pressure phase difference. 4, the low pressure alarm indication: battery-powered panel of the host, when the battery voltage is lower than the normal operating voltage, will produce low voltage alarm indication signal to alert staff to replace the battery, ensuring timely and accurate reflection of the high-pressure line fault condition. 5, automatic reset: When the indicator is an alarm signal, if there is no manual reset after setting time, the indicator can be automatically reset. Reset Time "fifth gear" Optional, (8 seconds, 6h, 12h, 24h, 48h, the default reset time is 12h) 6, manual reset: When an alarm indicator, can "reset on the trigger indicator host panel / Test "button to reset the alarm. 7. Automation: indicator generates a corresponding alarm indication signal, the alarm signal output can be remote. Indicators also acceptable return distant signal, the indicator for remote reset operation. 8, automatic test: Host panel by pressing the reset / test button, the panel L1, L2, L3, L4 indicator lights flashing indicator, automatic reset flashes nine times, but can also be manually reset and self-test operation adjacent to two times time is preferably 2 to 5 seconds. Third, the technical parameters: 1, short-circuit alarm current: 150A ~ 1500A ± 10%; delay 60ms ~ 3s adjustable (factory setting 800A ± 10%) 2, ground current alarm: 3A ~ 2000A ground may delay 60ms ~ 3s tune (the factory setting 20A ± 10%) 3, Power Supply: 3.6V ER14505 high-capacity lithium battery (for a period not less than 6 years) 4, Total standby current: ≤5uA 5, automatic reset time: 8 seconds, 6,12 (default), 24, 48 hours, etc. optional six indicator Protection class: Host IP40; sensor IP65 7, remote relay capacity: 24VDC 0.5A 230VAC 2A 8, the short-circuit current sensors to withstand the maximum current: 20KA 3S 9, the working environment : -25 ℃ ~ 75 ℃ 10, when the indicator indicates the status of the operating current ≤2mA four, the product composition: A, Host B sensor (short circuit 3, grounding a) C, fiber optic lines D, product manuals E, F foam , certificate V. Host Size: L * W * H: 97mm * 48mm * 78mm; installation opening dimensions: Length * Width: 92mm * 44mm (tolerance ± 0.3mm) six, installation instructions: three short-circuit sensors were installed in the cable The L1, L2, L3 phases and tighten. The ends of fiber optic cable to be inserted at the bottom of the host and the sensor fiber hole, ensure that the fiber cable to the host, and the sensor reliable connection.
