Abstract

The invention discloses a general-purpose tester of a disconnecting switch and relates to the technical field of switch testing devices. The general-purpose tester comprises an opening range and synchronizing measurement assembly, a contact head and contact finger base gap measurement assembly and a data receiving and analyzing terminal, wherein the opening range and synchronizing measurement assembly is used for measuring the opening range and synchronizing value of the disconnecting switch, the contact head and contact finger base gap measurement assembly is used for measuring the value of a gap between a contact head of the disconnecting switch and a contact finger base of the disconnecting switch, and the data receiving and analyzing terminal is used for receiving measured data, analyzing the measured data and displaying the measured data. The general-purpose tester has the advantages of being convenient to use, high in measurement accuracy and the like.

Description

technical field [0001] The invention relates to the technical field of switch testing devices, in particular to a comprehensive tester for isolating switches. Background technique [0002] Opening distance: refers to the distance between the contact and the finger when the isolating switch is opened and reaches the end position. The function of the isolating switch is to separate the live part so that the maintenance part has an obvious disconnection point. Generally, one is that the contact finger end or contact end of the isolating switch is charged at the end after the isolating switch is opened. Not enough will cause the uncharged side to be broken down in the air; second, if the opening distance is too large or too small, it will affect the synchronization and straightness of the three-phase isolation switch, so the opening distance is an item that must be tested during maintenance. [0003] Gap between contact and finger seat: the distance between the contact and the ...
