Intelligent temperature control voltage transformer

Abstract

The invention relates to an intelligent temperature control voltage transformer. In the voltage transformer, an optical temperature measuring element is embedded in a primary conductor of an electronic voltage transformer, an optical fiber for transmitting signals is synthesized into the insulation of the electronic voltage transformer, so that a temperature sensor and the electronic voltage transformer are integrated, the structure and the function of the electronic voltage transformer can be maintained, additional space is not needed, the structure of a switch cabinet is not needed to be damaged during application, special assembly, debugging and fixation on the site are not needed, the installation size is not changed, and the installation is simple and convenient. The intelligent temperature control voltage transformer is applied to intelligent power grid power transmission and transformation equipment, the structure of the switch cabinet can be greatly simplified, the number of electronic voltage transformer equipment in the system is reduced, and the reliability of system data transmission is improved.

Description

technical field [0001] The invention relates to an electronic voltage transformer, in particular to an intelligent temperature-controlled voltage transformer used in power transmission and transformation power equipment (such as a high-voltage switch cabinet). 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 power e...
