Abstract

The invention discloses a voltage measurement micro-needle device comprising a protection cylindrical chamber, a pushing device, a mini-sized probe, and a testing lead. The pushing device is disposed in the protection cylindrical chamber in a sleeved manner, and the pushing device is fixedly connected with the mini-sized probe. The mini-sized probe can carry out a forward-backward piston-type motion in the protection cylindrical chamber along with the pushing device. The mini-sized probe is produced by using a carbon nanotube, and has a diameter in a range from 10 nanometers to 100 nanometers. One end of the testing lead is connected with the mini-sized probe by a needle base disposed on the tail part of the pushing device. A voltage value is directly measured on an insulation conductor by using the voltage measurement mini-sized probe produced by using carbon nano-materials, and in addition, a measurement process is safe and effective, and a measurement result has high accuracy and high sensitivity.

Description

technical field [0001] The invention relates to electric power engineering measurement technology, in particular to a voltage measuring microneedle device. Background technique [0002] The measurement operation of voltage and current is the most frequently operated basic measurement operation in power engineering measurement, power scientific research and power production. The current measurement operation has realized the "direct" current measurement on the insulated wire through the "clamp current transformer", which brings great convenience to the power measurement work. However, at present, there is no instrument in the world that can measure the voltage on two insulated conductors. [0003] For example, in the live inspection of incorrect wiring of electric energy metering devices, on-site actual load verification of electric energy meters, and on-site anti-stealing, it is often necessary to measure the voltage of electric energy metering devices. At this time, the me...
