Problems solved by technology

[0002] At present, there are various forms of stainless steel resistors, most of which are too complex in structure, and the production process is quite cumbersome.
The screw rod of the original band-type stainless steel resistance is insulated with phlogopite, which is expensive, and the resistance bands are insulated with concave-convex porcelain parts, and the resistance bands are connected by welding. The welding point may be damaged when the product is used The phenomenon of partial discharge has a certain degree of damage to the life of the product itself and the surrounding vitality parts, and the performance is unreliable

Embodiment Construction

[0012] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0013] See figure 1 , The ribbon resistor provided by the present invention includes multiple resistor ribbons 6 connected in series and in parallel, and all the resistor ribbons 6 are combined by using a ceramic piece 8 . Wherein, the material of the resistance band 6 is a stainless steel band or a nickel-chromium band or the like.

[0014] In the strip resistor provided by the present invention, the stainless steel strip is the conductive resistance material, and different resistance values, temperature drift performance, and energy can be achieved by changing the material of the resistance strip 6 or connecting in series or parallel. Generally, the strip material used for the resistance band 6 is SUS304, and other grades of stainless steel, iron-chromium-aluminum alloy and nickel-chromium alloy can also be used. In order to a...

Abstract

The invention relates to a belt type large-power resistor. The belt type large-power resistor comprises a left bracket and a right bracket which are located at the left and right sides, wherein a plurality of resistor belts are arranged between the left bracket and the right bracket. The belt type large-power resistor is characterized in that each resistor belt is formed by wholly bending a stainless steel belt; a ceramic part with a bayonet is arranged between the adjacent two layers of resistor belts; the adjacent two layers of resistor belts are respectively fixedly arranged on an opening of the corresponding ceramic part; the corresponding two layers of resistor belts are insulated by the ceramic part and a screw rod is arranged in each ceramic part in a penetrating manner; the two ends of the screw rods are respectively connected and fixed with the left bracket and the right bracket. Compared with the prior art, the belt type large-power resistor has the following beneficial effects of safe and reliable product performances, large capacity, high electric conductivity, strong flow capacity, high temperature resistance, stable resistance value, corrosion resistance, long service life and simple structure; the belt type large-power resistor is convenient to combine and can be combined into a resistor with larger power.

Description

technical field [0001] The invention relates to a belt-type high-power resistor, which belongs to the field of power electronic components. Background technique [0002] At present, there are various forms of stainless steel resistors, most of which are too complex in structure, and the production process is quite cumbersome. The screw rod of the original band-type stainless steel resistance is insulated with phlogopite, which is expensive, and the resistance bands are insulated with concave-convex porcelain parts, and the resistance bands are connected by welding. The welding point may be damaged when the product is used The phenomenon of partial discharge has a certain degree of damage to the life of the product itself and the surrounding components, and its performance is unreliable. Contents of the invention [0003] The purpose of the present invention is to provide a stainless steel resistor with more reliable performance. [0004] In order to achieve the above obj...
