Abstract

Disclosed is a non-contact voltage measuring sensor (1) wherein a detection probe (11) is configured from a plate spring, and when an external force is applied, the detection probe is deformed to wind in the direction in which a tensile force of the plate spring operates.

Description

technical field [0001] The present invention relates to a voltage measuring device, in particular to a non-contact voltage measuring device for measuring a voltage applied to a wire without contacting the wire. Background technique [0002] Conventionally, there is known a non-contact voltage measuring device that measures an AC voltage (voltage to be measured) flowing through a conductive wire covered with an insulating coating while being in contact with the conductive wire. [0003] The non-contact voltage measurement device measures the measurement object voltage in the following manner. First, a detection probe for detecting a voltage is approached to an insulating covering portion of a wire. When the insulating covering part and the detection probe approach, coupling capacitance is generated between the detection probe and the lead wire. In the state where coupling capacitance is generated between the detection probe and the lead wire, if an alternating current flows...
