FIELD: measuring equipment.
SUBSTANCE: invention relates to devices for indication and measurement of voltage, in particular to voltage indicators, designed to determine presence/absence of operating and induced voltage on wires of overhead power transmission lines (OPTL), contact wires of electrified railways and current-carrying parts of other electrical installations. Summary: single-pole high-voltage combined multifunctional indicator comprises a working part, an insulating part and a handle separated from the insulating part of the indicator by means of a limiting ring. Indicator is made in a dielectric housing, which contains the first part of the housing and the second part of the housing with a detachable connection between the housing parts. Working part of the indicator is made in the first part of the indicator body and is equipped with a contact-tip and the first indication unit of voltage presence. Handle, the limiter ring and the insulating part of the indicator are made in the second part of the body. First part of the housing is equipped with the first connection unit, and the second part of the housing is equipped with the second connection unit. Handle is equipped with a second voltage indication unit and an antenna. Second display unit is equipped with a switch made in the form of a magnetically controlled contact. Second part of the housing contains a control unit, which contains a fixed part and a movable part, which is equipped with the first permanent magnet. Movable part of control unit is made with possibility to move first permanent magnet relative to magnetically controlled contact from position, in which the magnetically controlled contact is closed, to the position in which the magnetically controlled contact is open, and back. First connection unit is made in the form of the first threaded hole for connection to the threaded tip of the electrically insulating rod. Second connection unit is made in the form of the first threaded tip for connection to the first threaded hole.
EFFECT: broader functional capabilities.
