Abstract

The invention relates to a non-contact voltage detection and phase identification device, belonging to the technical field of electric power engineering live detection and monitoring. The device includes a sensor detection device, a bracket, a detector and a hand-held rod; the detector is located just below the sensor detection device, and is connected to the sensor detection device through the bracket; the detector is provided with LED indicators, a display screen, a switch, and an instrument shell body, laser emission receiver, sound alarm and control circuit; the top of the hand-held rod is fixedly connected with the bottom of the detector; the outer of the hand-held rod is covered with insulating rubber. The invention adopts non-contact measurement, can calculate the voltage of the maintenance line, judge the live condition of each phase transmission line, and give sound and light alarm prompts. The device has the advantages of reliable electrical inspection and safe operation.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering live detection and monitoring, and in particular relates to a non-contact voltage detection and phase identification device. Background technique [0002] A variety of high-voltage equipment is widely used in the power system, especially whether the high-voltage equipment is charged or not directly affects the personal safety of the operator. Electrical appliances play an extremely important role in the safe production of the power industry. [0003] Ordinary high-voltage electroscopes are only used for warning to remind maintenance personnel that the equipment is live. Ordinary high-voltage electroscopes are easy to use. You only need to hold the electroscope handle and touch the live parts of high-voltage equipment with the electroscope contacts. The existing contact high-voltage electroscopes on the market, because the electroscopes are in direct contact with the high-volta...
