Abstract

The invention relates to a measuring circuit, in particular to an aluminum electrolytic cell series ground insulation intensity measuring circuit which comprises an electrolytic cell and an interbus used for connecting the electrolytic cell. A voltage controlled power source is arranged between the electrolytic cell and the ground, a milliampere ampere meter is connected between the voltage controlled power source and the ground in series, a microampere ampere meter is connected between the milliampere ampere meter and the ground in series, and a voltmeter is connected between an adjustable end of the voltage controlled power source and the microampere ampere meter in parallel. The aluminum electrolytic cell series ground insulation intensity measuring circuit has the advantages that voltage is exerted between an electrolysis series and ground zero potential, detecting to voltage and a leakage current is conducted simultaneously, insulating intensity is calculated according to size and changing circumstances of ratio of the voltage and the leakage current, and accurate electrolytic series ground insulation intensity values are reached. The problem that measuring results are inaccurate caused by insufficient capacity of an insulating megger is solved effectively. The measuring circuit, in particular to an aluminum electrolytic cell series ground insulation intensity measuring circuit is close to actual circumstances after the electrolytic series is put in use, and therefore estimation to insulating intensity is effective.

Description

technical field [0001] The present invention relates to a measurement circuit, in particular to a measurement circuit for the ground insulation strength of an aluminum electrolytic cell series. The aluminum electrolytic process generally uses a DC system of several hundred thousand amperes for power supply. The DC system is an ungrounded system, and the aluminum electrolytic cell itself is The charged body and the aluminum electrolytic cell must be insulated from the earth. The measurement circuit is based on the continuous development of the aluminum electrolytic process technology and the continuous expansion of the aluminum electrolytic cell. The leakage method is used to measure the insulation strength of the ground. It belongs to the electrolytic workshop Insulation treatment and detection technology field. Background technique [0002] The production system of the aluminum electrolytic cell series is a charged body. In the production process, in order to ensure the per...
