小电流互感器现场检定接线方式的研究

Research of Connection Mode of the Small Current Transformer Site Verification

计量用电流互感器现场检定中,一次导线的接入方式一直是制约检定效率提高的主要因素,检定人员往往将大量的精力和体力消耗在一次接线上。因此,针对额定一次电流小于600 A的小电流互感器现场检定,提出了采用绝缘杆挂接一次导线接线方式,经现场验证,在保证检定试验准确合理进行的同时,可提高检定工作效率,是小电流互感器现场检定的首选接线方式。

Grid loss management is very important in electric company, which can reduce grid loss and enhance economic benefit. It is also a good way to put energy conservation and carbon emission reduction program of China into effect. This paper generally analyzes the actualities of grid loss management in China and the necessity of building grid loss management system. Then it gives a solution based on CIM and distributed Multi-data source technique. At last, it discusses the influence of smart grid supervision and control sys- tem to grid loss management.
