Problems solved by technology

In the circuit, resistors generally play the role of protection, voltage division, etc., and when the resistance value of the resistor changes, the voltage distributed on the resistor changes so that the working element cannot meet the requirements of the rated voltage and it cannot work normally; In some special circuits, there may be only one kind of energy-consuming element, the resistor, so when the resistance value changes, the impact on the circuit will be very large, especially when the resistor has been used for a long time and its resistance value becomes At zero time, the circuit will be short-circuited and dangerous
[0003] In some experiments, there are certain requirements for the accuracy of the resistance value of the resistor. If the actual resistance value of the resistor is different from the calibrated resistance value, it will have a considerable impact on the experimental results, and the existing resistors will be damaged after a long time of use. The phenomenon that the resistance value changes occurs, and the present invention makes improvements to the above-mentioned problems

Abstract

The invention discloses a variable resistor with self-checking and compensation functions. The variable resistor comprises a shell and a working cavity arranged in the shell. Wire conduits and connectors fixedly arranged at the tail ends of the wire conduits are symmetrically arranged at the left and right positions in the left and right walls of the working cavity, and the left and right connectors are communicated through wires arranged in the wire conduits. The variable resistor is simple in structure and convenient to use; with an electromagnet and a transparent tube with the scales, the resistance value of the resistor block can be detected after the resistor block is connected into a loop, and the resistance value of the resistor block can be visually reflected by changing the position of the iron block in the transparent tube. And the iron block can compensate the resistance value of the resistor block through a control device, so that the resistance value of the resistor blockis kept unchanged, and the working current in the circuit cannot be changed. And meanwhile, a safety resistor is arranged, so that the phenomenon of short circuit of the circuit is prevented, and thesafety in use is improved.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to a variable resistor with self-checking and compensation functions. Background technique [0002] In daily life or experiments, resistance is an electronic component that is often used. In the circuit, resistors generally play the role of protection and voltage division, and when the resistance value of the resistor changes, the voltage divided by the resistor changes so that the working element cannot meet the requirements of the rated voltage and it cannot work normally; In some special circuits, there may be only one kind of energy-consuming element, the resistor, so when the resistance value of the resistor changes, it will have a great impact on the circuit, especially when the resistor has been used for a long time and its resistance value becomes At zero time, the circuit will be short-circuited and dangerous. [0003] In some experiments, there are certain ...
