Close communication with wireless communications.The composition of system System including server, switch, fault detection terminal. Respectively installed in monitoring center, wire pole, overhead cable. 1.Monitoring center include: One set data processor with system main software. Monitoring center would be setup in the office of the power supply bureau dispatch, power substation, special line worker, etc. 2.Overhead cable installing part include: (1)Line fault monitor Can send and receive signals of line fault monitoring terminal, 3pcs/SET. Respectively installed in A,B,C three phase cable. Each monitor built-in ultra-low power consumption of the CPU and wireless RF module(Texas instruments (TI) Zigbee wireless communication methods) sent out the fault data, and sent the fault data to fault data collection terminal via wireless RF. (2)Fault data collection terminal Fault data collection terminal installed on the wire pole, one data collection terminal can receive data from nearby three line fault monitor, and analysis and process the fault data then sent to control center by GSM/GPRS. The fault date collection terminal is mainly composed of the solar panel, wireless receiving template, industrial GPRS module, CPU template, (Without SIM card). (As followed picture)
Detection principle Short circuit fault detection 1.(I)It≥300A It - Current start value mutation 2.I≥0.5IO I - Electric current changing rate, IO - Line current before short circuit 3.I=O I - Current after the line fault 4.0.02S≤T≤3S T - Current mutation time
Earth-fault detection: Uz － Line voltage≥3kV IL－ Loading current≥20A △IZ － Mutation current of the first half wave peak≥30A △Uz － Earth fault phase voltage drop ratio≥30% T1 － Normal operation time of the line≥30S T2 － The fault duration≥1ms T3 － Earth fault phase voltage continue drop duration before power outage≥60S
Detection of zero sequence current is greater than 15A (Can be set) The power distribution cable line 1.Short circuit fault detection: same as overhead line 2 Earth-fault detection: Detection of zero sequence current is greater than 15A (Can be set)System Software Installing For Windows XP/Win7,Mobile software for AndroidOrder Information: 1.Provide the circuit diagram and terminal installation position 2.Provide circuit parameters 3.Provide mobile GSM cardTest Report: Our products have already passed the test by CMA, CNAS,CE till now, and we also have ability to arrange other relevant testing and factory audit as your requirement.
