Abstract
The invention provides a piezoresistor with a tapered contact surface. An upward-protruding tapered body is disposed above a piezoresistor cylinder; a downward-protruding tapered groove is disposed below the piezoresistor cylinder; the size and depth of the tapered body above the piezoresistor cylinder and the tapered groove below the piezoresistor cylinder are correspondingly set to be consistent; when in use, a plurality of cylinders can be superposed and stacked based on the corresponding consistency of the upward-protruding tapered body and the downward-protruding tapered groove. With the above structure, the contact area between piezoresistors is increased, which facilitates the reduction of mutually-contacting resistors, the improvement of conductivity, the improvement of integral performance, and the improvement of the stacking stability of the integral structure.
Description
Technical field
The present invention relates to a kind of resistor, specifically a kind of varistor of conical contact face.
Background technology
At present, the lightning arrester that various power equipments are used is all to adopt zinc oxide varistor, and zinc oxide varistor has good non-linear voltage-current characteristic, during lower than its pressure sensitive voltage, is high-impedance state at two ends institute making alive; In the time of voltage pressure sensitive voltage, can conducting immediately, make it be low resistive state, absorb the energy that overvoltage produces, the amplitude of over-voltage, can effectively ensure the safety of system and equipment.Existing varistor is all cylindrical, and in the time that multi-disc stacks, its contact-making surface is circular flat, and the contact-making surface between each is not too large, thereby through-current capability is also not too large.
Summary of the invention
The object of the present invention is to provide a kind of varistor of conical contact face, can, in the time that multi-disc stacks, utilize its conical contact face, contact-making surface between each is strengthened, the favourable contact resistance that reduces, increases through-current capability, improves stability and improves varistor performance.
The present invention includes varistor cylinder, the technical scheme adopting is: the cylindrical top of described varistor is a protruding bullet, and below is the cone tank of an indent.
In technique scheme: the protruding bullet above varistor cylinder and the corresponding consistent setting of the cone tank of the indent of the below size depth.
Beneficial effect of the present invention is: by the configuration of technique scheme, formed one
The varistor of conical contact face, has solved the general little problem of cylindrical varistor contact-making surface.There is enlarge active surface, reduce contact resistance, increase through-current capability, increase stable
Property, improve the advantages such as varistor performance.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Embodiment
Shown in Fig. 1: the top of varistor cylinder 1 is a protruding bullet 2, and below is the cone tank 3 of an indent.The corresponding consistent setting of the big or small depth of cone tank 3 of the protruding bullet 2 of varistor cylinder 1 top and the indent of below.
