Abstract

The invention relates to a portable electric spraying apparatus used to on line test the hydrophobic of the composite insulator, which is formed by a wireless signal sending part, a hollow insulate operating rod, a wireless signal receiver, a micro-type electric pump control part and a electric spraying part, wherein the wireless signal sending part sends wireless signals which is transmitted into the wireless signal receiver and the micro-type electric pump control part through the inner channel of the hollow insulate operating rod to drive the micro-type electric pump to pump and spray the water so as to achieve the on line test of the hydrophobic of the composite insulator.

Description

technical field [0001] The invention relates to a detection device for the insulation of high-voltage equipment in a power system, in particular to a portable electric water spray device for on-line detection of the hydrophobicity of composite insulators. Background technique [0002] Hydrophobicity is one of the important indicators to measure the external insulation performance of composite insulators and RTV paint insulators. The water spray classification method (ie HC method) proposed by the Swedish Transmission Research Institute (STRI) is a hydrophobicity measurement method that can be used in the field. This method divides the hydrophobicity of the composite insulator surface into 7 grades and gives the grading criteria and standard pictures. The HC1 and HC7 grades correspond to the strongest and worst hydrophobicity respectively. Water spraying operation is an important step in measuring the hydrophobicity of composite insulators by HC method. In the test, an ordi...
