Problems solved by technology
However, with the increase of voltage level, the cable is getting higher and higher from the ground, the contact electroscope is no longer applicable, and the contact electroscope is not conducive to the personal safety of the testing personnel
[0003] Non-contact electroscopes now mostly use the principle of electric field induction, that is, detection by electric field sensors, but electric field sensors are expensive and susceptible to dust and surrounding environment interference
The patent with the application number 2016109711154 discloses a non-contact intelligent high-voltage DC electroscope, including a detector, a hand-held rod and a distance measuring system, etc. Although it can be detected by a sensor, it still needs to be hand-held for detection, which is not conducive to the detection of personnel. Personal safety, and the cost of sensor detection is high, the accuracy requirements are also high, and it is easily affected by the surrounding environment

The invention discloses an ultra-high voltage direct current non-contact intelligent electroscope, which belongs to the technical field of electric power detection, and includes an operation object, an inspection mechanism, and a winding mechanism. The inspection mechanism includes a casing, an electromagnetic conversion component, and a signal detection component. The rewinding mechanism includes a mobile housing, a display and a telescopic assembly. The telescopic assembly is arranged inside the mobile housing and is connected to the inspection mechanism for adjusting the position of the inspection mechanism. The display is used to display the detection structure of the inspection mechanism. The invention conducts non-contact detection on UHV DC through the inspection mechanism and winding mechanism, and the detection personnel do not need to be close to the UHV, thereby ensuring the safety of the detection personnel.
Description
technical field [0001] The invention belongs to the technical field of electric power detection, in particular to an ultra-high voltage direct current non-contact intelligent electroscope. Background technique [0002] In the process of high-voltage DC detection, the electroscope can detect whether there is a voltage electric field around it, and the traditional one is the contact electroscope. However, as the voltage level increases, the distance between the cable and the ground becomes higher and higher, and the contact electroscope is no longer applicable, and the contact electroscope is not conducive to the personal safety of the testing personnel. [0003] Non-contact electroscopes now mostly use the principle of electric field induction, that is, detection by electric field sensors, but electric field sensors are expensive and are easily disturbed by falling dust and the surrounding environment. The patent with the application number 2016109711154 discloses a non-cont...
