EKL-3 EKL-4系列面板型電纜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裝在配電網(wǎng)絡(luò)系統(tǒng)中的環(huán)網(wǎng)開關(guān)柜、電纜分支箱、箱變上，用于指示相應(yīng)電纜區(qū)段的短路和單相接地故障的一種實時監(jiān)測裝置。線路發(fā)生故障時，工作人員可借助指示器的報警指示，迅速確定故障區(qū)段，并找出故障點。同時，報警信息可實時發(fā)送到監(jiān)控中心的服務(wù)器，在監(jiān)控電腦的屏幕上顯示出故障所在的區(qū)域和具體位置，引導(dǎo)巡線人員迅速確定故障區(qū)段并找出故障點。該指示器為解決故障查找問題提供了最佳途徑。對提高工作效率，縮短停電時間，迅速恢復(fù)供電，提高供電可靠性和經(jīng)濟效益，有著十分重要的意義。
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 center's 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. 短路報警指示：短路傳感器在工作中檢測線路的電流，當線路發(fā)生短路故障且故障電流達到或超過報警電流整定值時，短路傳感器發(fā)出報警信號，通過光纖傳輸給主機，主機接收到此信號后，產(chǎn)生相應(yīng)的報警指示信號。
2. 接地報警指示：接地傳感器在工作中檢測線路的零序電流，當線路發(fā)生接地故障且接地故障電流達到或超過報警電流整定值時，接地傳感器發(fā)出報警信號，通過光纖傳輸?shù)街鳈C，主機接收到此信號后，產(chǎn)生相應(yīng)的報警指示信號。
3. 自動復(fù)位 ：當指示器發(fā)出報警信號后，如果無人工復(fù)位，則指示器將在設(shè)定的復(fù)位時間內(nèi)自動復(fù)位。
4. 人工復(fù)位 ：當指示器產(chǎn)生報警后，可通過觸發(fā)指示器主機面板上的“ 復(fù)位/ 測試”按鈕進行復(fù)位，以解除報警。
5. 測試 ：指示器可進行工作性能自檢。通過按下主機面板上的“ 復(fù)位/ 測試”按鈕并保持1.5 秒進行測試。
6． 智能化：指示器產(chǎn)生指示報警信號后，可將報警信號輸出遠傳。也可接收遠方的復(fù)位信號，對指示器進行遠方復(fù)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.
