Abstract

The invention discloses a novel thermal stimulation current measuring device, belongs to the field of electric medium physical measurement and study and aims to solve the technical problems that a conventional thermal stimulation current measuring device is poor in testing result repeating stability, and liquid nitrogen can be easily leaked off in a vacuum cavity when being cooled in a testing process. The device is technically characterized in that a moveable electrode module, a semiconductor refrigeration piece and a heat exchanger are arranged inside a vacuum chamber, and measurement on thermal stimulation current can be achieved. The device has the advantages of being rapid in cooling velocity, controllable in cooling process, high in measurement precision, accurate in measurement result and simple to operate; liquid nitrogen is replaced by using the semiconductor refrigeration piece and water under a certain experiment condition, experiment cost can be reduced, and security can beimproved; the device has wide application prospects in the field of medium material testing.

Description

technical field [0001] The invention relates to a thermally stimulated current measuring device, in particular to a novel thermally stimulated current measuring device, which belongs to the field of dielectric physical measurement and research. Background technique [0002] The Thermally Stimulated Current (TSC) method is an important experimental method that uses macroscopic physical methods to study the microscopic properties of the medium. The thermally induced current method is an effective method for studying dipole relaxation, trap parameters, space charge storage and transport, polymer structure relaxation and transformation, and molecular motion characteristics in polymers. Thermally stimulated current (TSC) is a tool to study the trap structure and the space charge storage and transport characteristics controlled by the trap structure in polymer materials. It is also an important means to study the structural transformation and molecular motion of polymers. The fie...
