Low-voltage electrical testing device

Abstract

The invention discloses a low-voltage electrical testing device. The low-voltage electrical testing device consists of a probe, a current-limiting resistor, a charging state display and a testing handle, and is characterized in that a multi-section insulating rod which can be assembled and disassembled is arranged at the front end of the electrical testing device; the two ends of each section of the insulating rod are respectively provided with a copper stud and a copper nut; the nut is embedded into the end surface of the insulating rod; the stud and the nut of every two sections of the insulating rod can be screwed together; the stud and the nut at the two ends of each section of the insulating rod are connected together through a conducting wire in the insulating rod; the stud and the nut at the two ends of the insulating rod at the most front end are connected with each other through the limiting-current resistor in the insulating rod; the probe is screwed on the insulating rod at the most front end in a threaded connection way; the charging state display is connected with the last section of the insulating rod; and the tail end of the charging state display is connected with the testing handle. By the low-voltage electrical testing device, operating personnel can test whether electrical equipment on an electric pole platform is charged or not without climbing on the electric pole platform, so that human physical strength is saved; the work efficiency and the safety are improved; and the personnel safety accidents are avoided.

Description

technical field [0001] The invention relates to an electric testing device for low-voltage power equipment. Background technique [0002] At present, because the existing low-voltage electroscopes (380V) are all miniaturized tools, the length of the probes of the electroscopes is not enough, and it is necessary to observe the light on and off status of the electroscopes at close range. Therefore, when inspecting whether the knife switch on the low-voltage side of the transformer on the pole platform is energized, the power distribution repair personnel of the electrical system need to climb onto the pole platform and conduct a power test near the transformer equipment. This method of operation not only consumes people's physical energy, but also has low operating efficiency, and there is a certain degree of danger, which can easily lead to personal safety accidents. Contents of the invention [0003] The object of the present invention is to provide a low-voltage electric...
