目前,在配电施工及建筑物维修中,基层单位因测量仪器短缺,往往由于暗配线路或绝缘导线某点断路,不能准确地确定故障位置,既延误了工期,又造成不必要的经济损失。针对这个问题,我们设计了一个由场效应、管感应信号、晶体管放大、发光二极管显示的导线断路测量仪,基本上可以解决这个问题。 At present, in the distribution construction and building maintenance, the grassroots units are often short circuited because of the lack of measuring instruments due to the hidden wiring or insulated wire, which can not accurately determine the fault location, which delays the construction period and causes unnecessary economic losses. . To solve this problem, we have designed a wire breakage measuring instrument that uses field effect, tube sensing signal, transistor amplification, and light-emitting diode display to basically solve this problem.
