Description

Technical Field

[0001] The present invention relates to the technical field of micro-current debugging modules, and more particularly to a polarization-depolarization micro-current debugging device. Background Art

[0002] The polarization-depolarization micro-current debugging module can be used to simulate and study polarization phenomena. By applying a specific micro-current to the electrode and observing the change of the electrode potential, the influence of factors such as different current densities, electrode materials, and electrolytes on polarization can be understood. This module can debug the depolarization process. It can control parameters such as the magnitude, direction, and time of the depolarization current to find the most effective depolarization method.

[0003] One of the simplest polarization-depolarization micro-current debugging modules is a picoammeter. This polarization-depolarization micro-current debugging module measures the electrode through the three-axis coaxial line and the measurement line at the rear. When the module is in use, the three-axis coaxial line and the measurement line are generally placed on a plane, and it is very easy to affect the measurement because of operating other instruments or accidentally touching the electrode wire. Especially for micro-current testing, the slightest movement of the electrode wire may affect the accuracy of the measurement result.

The staff may need to perform current tests in outdoor environments or on equipment frames. The suction cups 13 can stably place the electrode wires on uneven or vibrating planes (such as the outer shell of an electrical control cabinet, etc.), improving the test efficiency and safety; For the depolarization measurement of the electrolytic cell, the mounting cylinder 7 can be screwed into the mounting base 5, and the connecting seat 10 can be screwed into the lower part of the mounting plate 9, so that the chucks of the three-way wire 2 and the measuring wire 3 can be further away from the nearest plane, thereby expanding the application range of the device.

It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor.
