Technical Field
The utility model relates to an electric wire netting tests the electric field, especially relates to earthing device.
Background
According to the regulations of national grid company electric power safety work regulations (Q/GDW1799.2-2013), the technical measures for ensuring safety include: power failure; testing electricity; grounding; using a personal security line; hang the signboard and install the obscuration (rail). The electricity testing means that a qualified contact type electroscope with a corresponding voltage grade is used to verify that the line is really free of voltage before the working section of the power failure line is grounded. After the line experience is clear and no voltage exists, a grounding wire should be installed immediately and three phases are short-circuited. The complete set of grounding wire consists of a plurality of soft copper wires with transparent sheaths and a special wire clamp, and the sectional area of the wire clamp is not less than 25 mm2At the same time, the requirement of short-circuit current at the installation site should be met. Electricity testing grounding tool for daily power failure maintenance workThe transmission rope is carried by the electrician on the tower to the job needs, near suitable operating position, will test the electrography through the transmission rope and transmit to the tower on, test the electricity by the electrician on the tower looks, confirm that the circuit does not have the voltage after, will test the electrography and transfer to ground, hang the earth connection to the tower on again, install the earth connection by the electrician on ground to the circuit that has a power failure. This kind of traditional operating mode needs alone guardianship, is responsible for on the one person's tower and tests electric ground connection, and alone ground cooperation transmission work, the earth connection is heavy and the installation is loaded down with trivial details.
