Abstract
A capacitor battery for determining the dielectric constants of powdery samples comprises a battery body and an upper cover. An insulation pad is positioned in the battery body; metal electrodes are connected with the insulation pad in the movable way; the two electrodes have coaxial circular structures and, in excellent insulation, constitute two poles of the capacitor battery; the cavity between the two electrodes is a test sample cavity; a cavity is left between the insulation pad and the bottom of the battery body; the metal electrodes are introduced out of the capacitor battery respectively via two leaders through the cavity. In the utility model, the test sample cavity does not contact with the upper cover; the insulation pad and the cavity are arranged between the test sample cavity and the bottom of the battery body; the test sample cavity is not grounded, so the whole test sample cavity is excellently shielded from the outside and sample dielectric constants can be accurately determined. The circular electrodes can be taken off to provide convenience for sample cleaning and accurate weighing after determination.
Description
Technical field
The utility model relates to a kind of device that is applied to dielectric constant measurement, especially a kind of capacitance pool of surveying the pulverized specimen specific inductive capacity.
Background technology
The traditional capacitance pond is the structure based on three layers of coaxial ring-type, and material adopts copper or aluminium, and does surperficial anti-oxidant treatment.The capacitance pool inner and outer wall is drawn by two lead-in wires as the bipolar plates of tested solvent, and inwall is actually a solid copper cylinder, between the inside and outside wall (seeing bipolar plates as) as the sample chamber.Form good shielding during the earthing of casing, also increased bipolar plates distributed capacitance over the ground certainly.Owing to there is the distributed capacitance over the ground of inside and outside pole plate, also comprise the lead-in wire distributed capacitance over the ground of measuring the loop, numerical value is often greater than measured capacitance C
XTherefore, will introduce distributed capacitance and influence and can't measure as adopting dual-port measured.
Summary of the invention
The technical problems to be solved in the utility model is: when measuring the pulverized specimen specific inductive capacity, the structural design in traditional capacitance pond can make the measured capacitance indeterminacy.
The technical solution of the utility model is: the capacitance pool of surveying the pulverized specimen specific inductive capacity, comprise pond body and loam cake, insulating mat places in the body of pond, and the pond body leaves cavity between the bottom, metal electrode is fixed on the insulating mat, and metal electrode and insulating mat flexibly connect, and two electrodes are coaxial ring texture, good insulation constitutes capacitance pool the two poles of the earth, and the cavity in the middle of two electrodes is the sample chamber.
Be cylindricality with the fixing metal electrode of insulating mat wherein, another be annular, and two metal electrodes are drawn capacitance pool by two lead-in wires from cavity respectively.The utility model sample chamber does not contact with loam cake, and between the pond body bottom insulating mat and cavity is arranged, and is earth-free, whole sample chamber and extraneous good shielding, and the sample dielectric constant measurement is accurate.
The utility model has solved the operability of measuring, and has improved combination property.Ring electrode can take off, and is convenient to measure back cleaning sample, accurately weighs.The utility model capacitance pool has many use, as the specific inductive capacity that can be used for supporting measurement electric capacity and material etc.
