Abstract

The invention relates to a voltage sensor. The voltage sensor comprises a first electrode, a second electrode and an integrated capacitor, wherein one end of the integrated capacitor is connected withthe first electrode; and the other end of the integrated capacitor is connected with the second electrode. The voltage sensor provided by the invention has higher flexibility in actual use.

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to a voltage sensor. Background technique [0002] In the field of electric power technology, voltage measurement has a decisive influence on electric energy metering, relay protection, and automation equipment control, so related voltage measurement devices have emerged. [0003] The most common traditional voltage measurement device is a voltage sensor. The traditional voltage sensor includes a capacitive voltage sensor. When using a capacitive voltage sensor to measure the voltage of a transmission line, it needs to rely on the mutual capacitance between two electrodes. The mutual capacitance between the two electrodes is closely related to the size of the two electrodes of the capacitive voltage sensor, the distance between the two electrodes and the relative area of ​​the two electrodes. [0004] Therefore, due to the constraints of the size of the two electr...
