Problems solved by technology

The S-shaped winding method is used in the prior art. When the load rate changes, the resistance value of the resistor cannot be changed according to the actual demand of the load.
In the process of realizing the present invention, the inventors found that the prior art has at least the following problems: the volume is too large and it is not suitable for processing; the resistance value of the resistor cannot be changed according to the actual demand of the load, resulting in excessive current or rapid temperature rise

Abstract

The invention discloses a novel automatic-adjusting contact-type resistor which is composed of a rheostat, two contactors and an adjuster. The contactors are movably mounted on the rheostat respectively, and the adjuster and the rheostat are fixedly connected. A sensor contacts with a circuit to sense current, and the adjuster is driven through a control system to control the rheostat to contact with the contactors different in resistance value so as to adjust resistance value of the whole circuit. The novel automatic-adjusting contact-type resistor is ingenious in design, high in mechanical strength, stable and reliable in performance, safe, reliable and convenient to use.

Description

technical field [0001] The invention belongs to a resistor, in particular to a novel self-adjusting contact resistor. Background technique [0002] Resistors are generally directly referred to as resistances in daily life. It is a current-limiting element. After the resistor is connected to the circuit, the resistance value of the resistor is fixed. Generally, there are two pins, which can limit the current through the branch it is connected to. A resistor whose resistance value cannot be changed is called a fixed resistor. Those with variable resistance are called potentiometers or variable resistors. An ideal resistor is linear, that is, the instantaneous current through the resistor is proportional to the instantaneous applied voltage. Variable resistors for voltage division. On the exposed resistor body, one or two movable metal contacts are pressed tightly. The position of the contacts determines the resistance between either end of the resistor body and the contac...
