Automatic enamelled wire continues detection apparatus and method for detecting breakdown voltage of enamelled wire

Abstract

The invention discloses an automatic enamelled wire continues detection apparatus and a method for detecting a breakdown voltage of an enamelled wire. The detection apparatus comprises a rack; and a container for placing testing liquid for detecting an enamelled wire is arranged at the rack. A paying-off component, a take-up component, and a voltage detection component are arranged at the container. A testing power supply is installed at the voltage detection component; and a one-end electrode of the testing power supply is connected with the testing liquid in the container and a the-other-end electrode of the testing power supply is connected with the take-up component. A to-be-detected enamelled wire winds around the paying-off component; and the end of the to-be-detected enamelled wire is connected with the take-up component. The take-up component drives the to-be-detected enamelled wire to pass through the testing liquid through the paying-off component and to be rolled at the take-up component automatically by a centralized way; and the voltage detection component detects the real-time state of the to-be-detected enamelled wire passing through the testing liquid in real time. Therefore, the breakdown state of the membrane of the enamelled wire can be detected automatically, comprehensively and accurately; the efficiency is high; the detection precision is enhanced; and the using quality of the enamelled wire is ensured.

Description

technical field [0001] The invention relates to the field of enameled wire continuous detection, in particular to an automatic enameled wire continuous detection device and an enameled wire breakdown voltage detection method. Background technique [0002] Ordinary enameled wire online detection enameled wire withstand voltage, generally adopt the traditional enameled wire voltage twisted wire test method, mainly make the enameled wire into a twisted pair, apply voltage at both ends until the paint film of the enameled wire sample is broken down, and record the breakdown voltage. Although the use method and device are simple, the enameled wire is made into a twisted pair, the contact area is small, and the sample quantity is limited, so it is impossible to comprehensively evaluate the level and dispersion of the breakdown voltage of the enameled wire. Therefore, the existing detection device is additionally equipped with a container of saline solution, and the sample of a sec...

Problems solved by technology

This method increases the labor intensity of the inspection work, and at the same time, it cannot comprehensively and accurately determine the average state and dispersion of the breakdown voltage of the paint film of the enameled wire, and the manual inspection has low work efficiency and deviation in the inspection results.
