Problems solved by technology

[0003] During the use and research of the manganin shunt, the inventor found that the manganin shunt itself has a certain resistance value. As the load current increases, the manganin shunt itself becomes a heat source, and the manganin shunt itself becomes a heat source. Changes in the resistance characteristics of the current will affect the detection accuracy of the current

Embodiment approach

[0042] The embodiment of the present application discloses a current compensation method. refer to figure 1 , as an implementation of the current compensation method, comprising the following steps:

[0043] Step S101, acquiring the current detection value output by the manganin shunt.

[0044] Specifically, the processor is configured to be able to communicate with the manganin shunt; the communication method may be wired communication or wireless communication. When using an instrument with a manganin shunt for current detection or current sampling, the manganin shunt can send the detected current detection value to the processor, so that the processor can obtain the current detection value output by the manganin shunt .

[0045] Step S102 , input the current detection value into the generated current compensation model to obtain the current compensation value; the current compensation value is a real number; in the current compensation model, there is a mapping relations...

Abstract

The invention relates to a current compensation method and system, computer equipment and a readable storage medium, and relates to the technical field of electrical measurement, and the current compensation method comprises the steps: obtaining a current detection value outputted by a manganese-copper shunt; inputting the current detection value into a generated current compensation model to obtain a current compensation value; in the current compensation model, the current compensation value and the current detection value have a mapping relation; the current compensation value is a real number; the current compensation value is used for reducing the influence of the temperature of the manganin shunt on the detected current detection value; and obtaining a compensated current detection value based on the current detection value and the current compensation value. The manganese-copper diverter detection device has the effect of improving the detection accuracy of the manganese-copper diverter.

Description

technical field [0001] The present application relates to the technical field of electrical measurement, in particular to a current compensation method, system, computer equipment and readable storage medium. Background technique [0002] Manganin shunts have the advantages of DC resistance and low cost, and are widely used in current sampling of various instruments. [0003] During the use and research of the manganin shunt, the inventor found that the manganin shunt itself has a certain resistance value. As the load current increases, the manganin shunt itself becomes a heat source, and the manganin shunt itself becomes a heat source. The resistance characteristics of the sensor change, which affects the detection accuracy of the current. Contents of the invention [0004] In order to improve the detection accuracy of the manganin shunt, the present application provides a current compensation method, system, computer equipment and readable storage medium. [0005] In t...
