The invention is applicable to the technical field of power maintenance equipment, and provides an electric leakage indicator for a pole. The electric leakage indicator comprises a current transformer, a sensing unit and an alarming unit; a coil at a primary side of the current transformer winds the pole, the two ends of a coil at a secondary side of the current transformer are connected with a first input end and a second input end of the sensing unit respectively, a first input end of the alarming unit is connected with a first output end of the sensing unit, and a second input end of the alarming unit is connected with a second output end of a primary circuit power source. The alarming unit comprises an alarming apparatus, when the pole has electric leakage, the coil at the primary sideof the current transformer senses current, the coil at the secondary side of the current transformer is electrified, the sensing unit is electrified, the alarming unit receives signals of the first output end and a second output end of the sensing unit, and the alarming apparatus of the alarming unit conducts alarming. The problem in the prior art that hidden safety hazards are caused when the pole has electric leakage is solved.
Description
technical field [0001] The invention belongs to the technical field of electric power maintenance equipment, and in particular relates to an electric pole leakage indicator. Background technique [0002] Electric poles include power transmission poles and support poles for electrical equipment, such as street light poles. When it rains, the rainwater will make the poles form a conductor. When the line is damaged, the leakage position will form a path with the earth. Electric shock accidents will occur when people approach the poles, causing potential safety hazards. Contents of the invention [0003] In view of this, an embodiment of the present invention provides an electric pole leakage indicator to solve the problem in the prior art that electric pole leakage causes potential safety hazards. [0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a pole leakage indicator, including a current transformer, a se...
