Abstract

The invention discloses a contact type electricity verification apparatus, and relates to the technical field of an apparatus for measuring electrical variables. The electricity verification apparatus comprises a cylindrical insulation rod, a contact type electroscope is fixed at the outer side of the end portion of the insulation rod through a first angle adjusting device, the contact type electroscope is electrically connected with a controller, an electromagnetic induction sensor is disposed at the end portion of the insulation rod for sensing magnetic field information around an electrified device, a pick-up head is fixed at the end portion of the insulation rod through a second angle adjusting device, the lens of the pick-up head is oriented towards the electricity verification part of the contact type electroscope, an acousto-optic alarm device and a display are connected with the signal output end of the controller, and a power supply module is used for providing working power supply for modules needing power supply in the electricity verification apparatus. The electroscope provided by the invention has the advantages of high reliability, safe application and convenience.

Description

technical field [0001] The invention relates to the technical field of devices for measuring electrical variables, in particular to a contact type electroscope. Background technique [0002] An electroscope is an instrument that can detect whether an object is charged. For example, a high-voltage electroscope can detect high-voltage equipment or power transmission and distribution lines to determine whether there is electricity in the high-voltage equipment or power transmission and distribution lines, thereby ensuring the safety of power maintenance personnel. The electroscope in the prior art usually includes an electroscope host and an electroscope metal probe fixedly connected to the electroscope host. An ordinary circuit board is arranged in the electroscope host, and the electroscope metal probe and the ordinary circuit board in the electroscope host electrical connection; specifically, the common circuit board in the electroscope host is also connected with an alarm....
