Description
- Small Current Grounding Line Selection Device
- Nearly 100% of the correct rate of the election line
- Since 2006, YH-B811, respectively, Xi'an Jiaotong University, Cape Laboratory, Guangxi Academy of Sciences, such as over 10,000 anti-real, dynamic mode, inversion experiment, the correct rate of more than 98% line selection
- So far, it is the first and only one in a number of laboratories to carry out dynamic test small current grounding line selection device
- October 2007, YH-B811 in Xi'an Jiaotong University completed 1269 digital dynamic test, the correct line selection 1248 times, the correct line rate really 98.3%
- August 2008 in the Cape Laboratory (formerly the National Relay Quality Inspection Center) completed 120 dynamic test, the correct rate of 100% line selection.
- From September to November 2011, YH-B811 completed 340 dynamic model tests at the Electric Power Research Institute of Guangxi Power Grid Corporation. The correct selection line was 334 times, and the correct rate of selection was 98.2%
- It is the only one in the power grid, oil, coal, metallurgy and other industries in many fields done on-site artificial grounding test of small current grounding line selection device
- 2009 - 2013, YH-B811, respectively, in the water power supply bureau, Shenzhen Power Supply Bureau, Kaili Power Supply Bureau, Text Electric Academy, Xiangtan Coal Mine, Daqing Oilfield, Xinshanzi Petrochemical, Laiwu Steel Group, Guizhou Power Grid 9 Times the artificial ground test, the correct line selection 40 times, the correct rate of true selection line 95.2%
- As of April 30, 2013, the country 617 operating the scene, a single phase ground a total of 5739 times, of which the correct line selection 5661 times, the correct rate of 98.64%
- Revolutionary breakthrough in the technical principles
- The YH-B811 small current line selection device adopts the theory of line selection based on the characteristics of the transient zero sequence current in the adaptive buffering feature band. The high-speed sampling, extraction and analysis of the harmonic current of the instantaneous zero sequence current
- The use of the unique nature of the frequency band to identify the fault line. Adapt to all the center point of the indirect grounding system, not the system operation and a variety of fault conditions
