Embodiment Construction

[0056] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0057] In the prior art, for the voltage detection of the transmission line of the power system, a contact voltage measurement method is usually used, wherein the contact voltage measurement method refers to connecting the probe of the electromagnetic transformer with the metal wire inside the transmission line, The voltage on the transmission line is then measured based on the principle of electromagnetic induction. Among them, when connecting the probe of the electromagnetic transformer to the metal wire inside the transmission line, it is necessary to first control the ...

Abstract

The invention relates to a non-contact voltage measurement method and device, computer equipment and a storage medium, and belongs to the technical field of electric power test. According to the non-contact voltage measurement method and device, the computer equipment and the storage medium provided by the embodiments of the invention, a reference voltage signal Ur is input into an electrical loop, and the phase difference between the reference voltage signal Ur and the voltage Us of a circuit to be measured is controlled to be theta degrees and (180 degrees-theta) degrees; and then the voltage of the circuit to be measured is calculated based on the current, measured in the two states, in the electrical loop and the current measured under the condition that no reference voltage signal exists in the electrical loop (namely, a third reference voltage signal is zero), and when the device measures the voltage of the circuit to be measured, an insulating layer of the circuit to be measured does not need to be damaged; The non-contact voltage measurement method and device have the characteristics of simple structure and low cost, so that the voltage measuring cost can be reduced.
