The invention discloses an electric leakage detection protection system that includes a telescopic rod; the telescopic rod comprises a first vertical rod and a second vertical rod; the second verticalrod sleeves the upper end of the first vertical rod; a second threaded gear is rotationally mounted in the middle of the interior of the first vertical rod through a bearing; the middle part of the second threaded gear is in threaded connection with a threaded rod; the upper end of the threaded rod is fixed with the lower surface of the second vertical rod; the first gear is engaged with the lower part of one side of the second threaded gear; according to the invention, the length of the telescopic rod is convenient to adjust; the first gear can drive the second threaded gear to rotate by rotating the knob, so the threaded rod can move in the vertical direction and drive the second vertical rod to move up and down, so that the change of the total length of the first vertical rod and the second vertical rod is realized, and the extension and retraction of the telescopic rod are realized. According to the invention, a protection sleeve capable of extending and retracting through a longspring is arranged, so that the loss of the protection sleeve is avoided.
Description
technical field [0001] The invention relates to the technical field of electric leakage detection, in particular to an electric leakage detection and protection system. Background technique [0002] Leakage is caused by a certain potential difference between the electrical enclosure and the live wire of the mains for some reason and the ground. In order to avoid fires in life, it is usually necessary to use a leakage detection system for detection. The patent application number 201721636554.6 proposes an electric fire leakage detection device for electrical appliances. The leakage detection device can adjust the angle of the detection head and adjust its overall length, but the way to adjust the length is inconvenient. Contents of the invention [0003] The object of the present invention is to provide an electric leakage detection and protection system to solve the problem of inconvenient adjustment of the length of the electric leakage detection device in the prior art....
