Abstract

The invention provides a current transformer output voltage rapid test device and belongs to the technical field of current transformer testing. With the current transformer output voltage rapid testdevice adopted, the problem of low testing efficiency of a current transformer in the prior art can be solved. The device comprises a testing machine, a primary electric conduction wire and a vertically-arranged probe; the probe is arranged in the testing machine in a penetrating mode; the probe is connected with a voltage testing device and can be electrically connected with the pin of a currenttransformer to be tested; the primary electric conduction wire is erected on the testing machine through an insulating structural member and is located above the probe; the primary electric conductionwire is connected with a power source and can penetrate through the inner side of the iron core of the current transformer to be tested; the testing machine is a platform on which the probe and the current transformer to be tested can be installed and carried; the current transformer to be tested can be connected with the probe by means of the gravity of the current transformer to be tested, so that a pin welding step can be omitted; large-current operation is avoided; and testing efficiency and safety are improved.

Description

technical field [0001] The invention relates to the technical field of current transformer testing, in particular to a rapid testing device for the output voltage of a current transformer. Background technique [0002] Current transformers are the main devices for all kinds of household appliances to monitor their own power and current, realize safety and self-protection. The stability and accuracy of their output voltage are the necessary content and key quality indicators for factory and factory inspections. [0003] At present, for such functional tests of current transformers, manual welding is usually used to electrify the pins, and the wires and resistors are penetrated to test the output voltage with a multimeter. Such methods have problems such as low welding test efficiency and potential safety hazards in high current operation in actual operation. Especially when there is an abnormality in the quality of the device and it is necessary to fully check the performanc...
