EKL-3 EKL-4系列面板型电缆短路接地故障指示器
Earth Fault & Short Circuit Indicator EKL-3.EKL-4
概述
EKL3. EKL-4面板型故障指示器是配套安装在配电网络系统中的环网开关柜、电缆分支箱、箱变上，用于指示相应电缆区段的短路和单相接地故障的一种实时监测装置。线路发生故障时，工作人员可借助指示器的报警指示，迅速确定故障区段，并找出故障点。同时，报警信息可实时发送到监控中心的服务器，在监控电脑的屏幕上显示出故障所在的区域和具体位置，引导巡线人员迅速确定故障区段并找出故障点。该指示器为解决故障查找问题提供了途径。对提高工作效率，缩短停电时间，迅速恢复供电，提高供电可靠性和经济效益，有着十分重要的意义。
General description:
EKL3.EKL-4 panel FAULT indicator is a complete system installed on a distribution network in the ring network switch cabinet, cable branch box, box variable on the cables used to indicate the corresponding sections of the short-circuit and single-phase ground fault of a real-time monitoring device. Line failure, the staff can make use of indicator alarm instructions, to quickly identify fault section and find the point of failure. At the same time, real-time alarm information
can be sent to the monitoring centers servers for monitoring the computer screen failure and specific location of the region where the guide line patrol officers to quickly identify fault section and find the point of failure. This indicator issues to address the failure to find the best way. Improving work efficiency, reduce outage time, the rapid restoration of electricity, improve reliability and economic benefits of great significance.
主要功能
1. 短路报警指示：短路传感器在工作中检测线路的电流，当线路发生短路故障且故障电流达到或超过报警电流整定值时，短路传感器发出报警信号，通过光纤传输给主机，主机接收到此信号后，产生相应的报警指示信号。
2. 接地报警指示：接地传感器在工作中检测线路的零序电流，当线路发生接地故障且接地故障电流达到或超过报警电流整定值时，接地传感器发出报警信号，通过光纤传输到主机，主机接收到此信号后，产生相应的报警指示信号。
3. 自动复位 ：当指示器发出报警信号后，如果无人工复位，则指示器将在设定的复位时间内自动复位。
4. 人工复位 ：当指示器产生报警后，可通过触发指示器主机面板上的“ 复位/ 测试”按钮进行复位，以解除报警。
5. 测试 ：指示器可进行工作性能自检。通过按下主机面板上的“ 复位/ 测试”按钮并保持1.5 秒进行测试。
6． 智能化：指示器产生指示报警信号后，可将报警信号输出远传。也可接收远方的复位信号，对指示器进行远方复位
操作。
Main function:
1. Short-circuit alarm instructions: short-circuit sensor to detect lines in the work of current, short-circuit faul toccurs when the circuit and the fault current reached orexceeded the alarm current setting value, the short-circuit sensor alarm signals through the optical fiber transmission to the host, the host receives this signal After the instructions to produce alarm signals.
2. Grounding alarm instructions: ground sensors to detect the line in the work of zero sequence current, ground fault occurs when the circuit and earth fault current to reach or exceed the current alarm setting value, the ground sensor alarm signals through the optical fiber transmission to the h o s t , t h e h o s t r e c e i v e s t h i s s i g n a l t o g e n e r a t e a corresponding alarm indication signal.
3. Auto-Reset: When the indicator alarm signal, if there is no manual reset, then the indicator will be reset at the set time automatically reset.
4. Manual reset: When the indicator generated the alarm, the host can trigger the indicator panel on the "Reset /Test" button to reset to remove the alarm.
5 . T e s t : p e r f o r m a n c e i n d i c a t o r c a n b e t h e w o r k o f self-test. The host panel by pressing the "Reset / Test"button and maintain the 1.5 seconds for testing.
6. Intelligence: indicator alarm signal generated instructions can be alarm signal output FET. Can also be reset to receive distant signals to remote reset operation of theindicator.
