Primary and secondary fusion voltage and current integrated sensor

Abstract

The invention discloses a primary and secondary fusion voltage and current integrated sensor, and relates to the technical field of state grid primary and secondary fusion equipment. The main points of the technical scheme are that the sensor comprises a body connected to an outdoor high-voltage line, and the body is internally provided with an electricity taking sensor, a voltage sensor and a current sensor; the body is further provided with a current wiring end and a wire output port which are electrically connected with an outdoor high-voltage wire; the current sensor is electrically connected to the current wiring end and is used for outputting a phase current sampling signal; the electricity taking sensor is electrically connected to the current wiring end and is used for outputting a220v standard voltage; the voltage sensor is electrically connected to the current wiring end and used for outputting a phase voltage sampling signal. The sensor can output the phase voltage samplingsignal and the phase current sampling signal at the same time, has the power supply function, and has the advantages of simple structure, stable cable distribution and convenient assembly.

Description

technical field [0001] The invention relates to the technical field of primary and secondary fusion equipment of the State Grid, and more specifically, it relates to a primary and secondary fusion voltage and current integrated sensor. Background technique [0002] In the construction of distribution network automation system, the problem of power acquisition of automation devices has always been a major bottleneck in the upgrading and transformation of distribution network lines. Some use electromagnetic voltage transformers to obtain power, some use current transformers to obtain power, and some The use of solar power generation devices to obtain electricity requires either large investment in implementation and application, or complex and unreliable wiring, and may be affected by external factors such as operating environment, climate change, and line load, which limits the development of distribution network automation. At the same time, in the prior art, each component ...

[0002] In the construction of distribution network automation system, the problem of power acquisition of automation devices has always been a major bottleneck in the upgrading and transformation of distribution network lines. Some use electromagnetic voltage transformers to obtain power, some use current transformers to obtain power, and some The use of solar power generation devices to obtain electricity requires either large investment in implementation and application, or complex and unreliable wiring, and may be affected by external factors such as operating environment, climate change, and line load, which limits the development of distribution network automation.

[0003] However, this way of setting each component separately will lead to weaker stability of the wiring line, and inconvenient assembly and installation.
