Abstract

In order to solve a fever problem caused by improper place of the disconnector, interval between the contact terminal and contact finger, and asynchronous three-phase switch on, and reduce load losses caused by non-scheduled outage, this project studies the general-purpose tester of the disconnector. The general-purpose tester of the disconnector is composed of two modules: hardware system and software system. The hardware system includes the measuring unit of the disconnector and wireless data transmission unit. The software system contains the ultrasonic ranging software algorithm based on NUC472, DSP combined algorithm design, as well as analysis and display terminal design based on the virtual instrument.
