Problems solved by technology

[0002] Due to the complex situation of the rural power distribution network and the harsh environment, there are still many links that need to be improved urgently in the operation of the leakage protector. According to the operation of the leakage protector in the current practical application, due to the leakage in the line and it is not easy to check, It is impossible to monitor long-distance residual currents such as overhead lines. When encountering overhead lines, it is necessary to climb poles to measure them, so that there are many safety hazards in the actual operation of power supply lines.

Abstract

The invention relates to a residual current detecting and positioning device. The device comprises a body, a connecting sleeve assembly and an insulating telescopic rod which are used in combination with the body; the body comprises a housing; the lower end of the housing is provided with a threaded interface; the threaded interface is in threaded connection with the connecting sleeve assembly andis connected with the insulating telescopic rod through the connecting sleeve assembly; the upper end of the housing is provided with a U-shaped fixing frame; the U-shaped fixing frame is symmetrically provided with a left clamp and a right clamp; the tops of the left clamp and the right clamp abut against each other; the bottoms of the left clamp and the right clamp are rotationally arranged onthe U-shaped fixing frame through pin shafts respectively; the pin shafts are provided with torsion springs for closing the left clamp and the right clamp and driving mechanisms for driving the left clamp and the right clamp to open and close; the front panel of the housing is provided with an operation panel; the operation panel is provided with a liquid crystal display, a power source switch, achange-over switch, a setting button, a charging indicator lamp and a look-up switching button; and a charging assembly is arranged on the side surface of the housing. With the residual current detecting and positioning device of the invention adopted, current leakage fault points can be located safely, quickly and conveniently; and as for the overhead lines of complex low-voltage transformer power supply areas, a user does not need to climb a tower or a high position to carry out measurement.
