Abstract
The invention belongs to an electric element and in particular relates to a resistor. The technical scheme of the invention is that: a high-power resistor comprises a porcelain tube [1], a first resistance wire [2] and first lug plates [3], wherein the first resistance wire [2] is wound on an outer surface of the porcelain tube [1]; and the first lug plates [3] are arranged at two ends of the first resistance wire [2]. The high-power resistor is characterized in that: a second resistance wire [4] is also wound on an inner surface of the porcelain tube [1]; and second lug plates [5] are connected with two ends of the second resistance wire [4]. The high-power resistor has the advantages that: a single-tube power is at least doubled under the condition of forced cooling; the volume and weight are reduced obviously than those of the conventional high-power resistor; the high-power resistor is convenient to carry to a detection field; and an internal resistor and an external resistor can be connected in series or in parallel and can be applied individually.
Description
Technical field
The invention belongs to a kind of electrotechnical elements, particularly a kind of resistor.
Background technology
High-power resistance is usually used in the calibrating of large power supply.The main deficiency of existing high-power resistance is that volume, weight are too big, is difficult for carrying.
Summary of the invention
The objective of the invention is: a kind of volume, the less high-power resistance of weight are provided.
Technical scheme of the present invention is: a kind of high-power resistance, comprise: porcelain tube, be wrapped in first resistance wire of described porcelain tube outer surface, and first lug plate at the described first resistance wire two ends, it is characterized in that: also be wound with second resistance wire at described porcelain tube inner surface, the described second resistance wire two ends are connected with second lug plate.
The present invention's single tube power under the air blast cooling condition doubles above, and volume and weight obviously reduces than existing high-power resistance, and it is on-the-spot to calibrating to be convenient to portable, and inside and outside two resistance can serial or parallel connection, also can use separately.
