Description

A portable electroscope

technical field

The utility model relates to the technical field of electric power systems, in particular to a portable electroscope.

Background technique

When the power system power equipment is powered off for maintenance, in order to prevent the power failure equipment from causing safety hazards to the workers, it is necessary to install grounding wires on all sides where the power may come in. Before installing the grounding wire to the equipment, it is necessary to test the power of the equipment to ensure that the equipment has no voltage before installing the grounding wire. Due to the high line structure in some substations, the telescopic insulating rod (3) of the existing electroscope may not be long enough after being fully pulled, so an insulating ladder must be used, and the operation and maintenance personnel can complete the electrical inspection of the equipment by standing on the ladder. Standing on the ladder for electrical inspection has the following three disadvantages: first, carrying the ladder increases the workload of operation and maintenance personnel and prolongs the power outage time; second, the operation and maintenance personnel may fall from a high altitude when standing on the ladder for electrical inspection; When standing on the ladder to test the electricity, the operation and maintenance personnel may not pay attention to the safe distance from the nearby live parts, which may cause potential safety hazards. The structure of the currently used telescopic electroscope is not durable. When stretching, the insulating rods of each section are easily disconnected and the insulating rod is broken. even delay operations. In addition, the structural design specifications of the electroscope tip (4) of the currently used electroscope are not uniform, and it is inconvenient to carry multiple electroscopes when testing equipment with multiple voltage levels. Moreover, the currently used electroscope pen head (4) uses a button battery, and the battery power cannot be known before use, which may delay the power test operation during use due to insufficient power.
