关于TV二次回路压降系列测试的解析

Analysis to a Series of Measuring on the TV Second-level Route Voltage Reduce

本文系统并且深入地分析了TV二次回路压降的系列问题。针对技术监督检查中发现的问题,指正了判定TV二次回路压降是否超标的合理方法;阐述了应采取自然法进行技改以减小压降;并指明了现场测试TV二次回路压降的正当接线及应遵循的重要技术操作原则。

The paper analyzes a series of problems on TV secondary circuit voltagedrop systematicaUy. Aiming at the questions found in technical supervision and check, it correctes reasonable way of judging whether TV secondary circuit voltagedrop oversteped the target, expoundes that we ought to adopt nature-methods of technical reforming for lightening voltage reduce; and shows clearly the proper connections of TV secondary circuit voltagedrop at scene and the important technical operating principle which should be followed.
