The invention relates to overhead line clamp measuring equipment, method and device, wherein the overhead line clamp measuring equipment comprises: a line patrol robot moving along an overhead line and a processor connected to the line patrol robot; the line patrol robot includes a voltage measurement instrument, and a top voltage measurement probe and a bottom voltage measurement probe connectedto the voltage measurement instrument; when the line patrol robot moves to a preset distance from the overhead line clamp, the top voltage measurement probe is driven to contact the overhead line andthe bottom voltage measurement probe is driven to contact the overhead line; and the voltage measurement instrument measures the voltage and voltage phase angle of the overhead line clamp in the current operating state by the top voltage measurement probe and the bottom voltage measurement probe which are firmly contacted with the overhead line, and sends the voltage and the voltage phase angle tothe processor. The invention can effectively prevent the unstable transmission of the electric energy caused by the bad connection, or the occurrence of a safety accident such as lead fusing caused by the excessive temperature.
Description
technical field [0001] The invention relates to the technical field of measurement of overhead line clamps, in particular to measuring equipment, methods and devices for overhead line clamps. Background technique [0002] As a kind of connecting hardware widely used in high-voltage overhead transmission lines, strain clamps are related to whether the power transmission network can safely and stably transmit electric energy. In actual engineering, due to factors such as oxidation and corrosion of wires and connecting hardware, and lax construction technology, poor connections occur at the drainage connection parts. In recent years, with the substantial increase in transmission capacity of transmission lines, overheating of fittings has occurred from time to time. [0003] For the detection method of traditional overhead line clamps, usually under the operating state of the clamps, the infrared temperature measurement method is used to obtain the infrared pictures of the clam...
