Electronic current voltage combined type mutual inductor with temperature measuring apparatus

Abstract

Provided is an electronic current voltage combined type mutual inductor with a temperature measuring apparatus and the invention relates to a mutual inductor. The invention provides an electronic current voltage combined type mutual inductor with a temperature measuring apparatus. The electronic current voltage combined type mutual inductor with the temperature measuring apparatus is characterized in that the temperature of the electronic voltage combined type mutual inductor can be monitored in real time; the temperature measuring apparatus is in one body with the mutual inductor and the structure and the functions of the electronic current voltage combined type mutual inductor are maintained. The invention comprises a current voltage combined type mutual inductor. A temperature sensor is provided inside the current voltage combined type mutual inductor. The temperature sensor is in one body with the voltage combined type mutual inductor. The temperature sensor is provided with optics temperature measurement elements and signal transmission fibers. The optics temperature measurement elements are embedded in the electronic current voltage combined type mutual inductor and the signal transmission fibers are provided in the electronic current voltage combined type mutual inductor.

Description

technical field [0001] The invention relates to a transformer, in particular to an electronic current-voltage combined transformer with a temperature measuring device used in power transmission and transformation power equipment (such as a high-voltage switchgear). Background technique [0002] The strategic goal of my country's "strong and smart grid" is to be strong and intelligent. With the deepening of my country's strong and smart grid construction and the continuous expansion of power transmission coverage, once an accident occurs in a particularly large power grid and cannot be eliminated quickly, it is likely to cause damage and uncontrollable chain reactions, resulting in large-scale and long-term power outages. The political stability and economic security of the society have a serious impact, which is unmatched by accidents in other industries. For this reason, it is urgent to carry out all-round real-time or regular online monitoring of the operation status of po...

AI Technical Summary

Problems solved by technology

[0007] There are many deficiencies in the various temperature measuring devices currently used, such as: they cannot be installed independently, they must be attached to the conductive arm or busbar of the handcart; The impact of high current and voltage shocks on the product; the impact on the insulation and withstand voltage of power equipment after installation is not considered; the stability of the product working in an abnormal high temperature environment is not considered; especially there is no intelligent function, etc.
