A Position Marking Tool for High Frequency Partial Discharge Measurement

Abstract

The invention discloses a high-frequency partial discharge measurement position marking tool, which comprises a base, travelling universal wheels arranged at the bottom part of the base, a rack-type support arranged at the upper part of the base, a gear arranged at the left side of the rack-type support, an axle sleeve, a rotating handle, a special-shaped frame, and a guide groove, wherein a height scale is arranged on the rack-type support; the rack-type support is fixedly connected with the base; the axis part of the gear is provided with a gear shaft; the gear and the gear shaft are fixedlyconnected; the axle sleeve is arranged on the gear shaft; the rotating handle is fixedly connected with the gear shaft; the special-shaped frame is arranged between the gear and an L-type frame; theguide groove is arranged in the L-type frame; the special-shaped frame comprises a limiting pin arranged at the right lower part, a guide groove, an open rectangular guide groove, an upper guide wheeland a lower guide wheel; a hard paper board is arranged at the upper part of the L-type frame and the special-shaped frame; and a hollowed word and a hollowed long strip are arranged on the hard paper board, a spraying mark can be positioned, and the spraying marking position is accurate. When devices such as a transformer and a current transformer perform partial discharge measurement, height errors are reduced.

Description

technical field [0001] The invention relates to the field of transformer high-frequency partial discharge measurement and test in substation maintenance. Background technique [0002] Select appropriate test points according to different electrical equipment and site conditions, and keep the same position for each test point, so as to facilitate comparative analysis. When measuring partial discharge of equipment such as transformers and current transformers, the last measurement location is not clearly recorded in actual work, especially when measuring transformers, it can be measured at the core grounding down conductor or at the clamp grounding down conductor. Moreover, the height of each measurement is not necessarily the same, so the requirement of "keeping the position of each test point consistent" may not be met. At the same time, it is required that the marking is simple and practical, and the storage time is long. Contents of the invention [0003] The object of...

When measuring partial discharge of equipment such as transformers and current transformers, the last measurement location is not clearly recorded in actual work, especially when measuring transformers, it can be measured at the core grounding down conductor or at the clamp grounding down conductor. Moreover, the height of each measurement is not necessarily the same, so it may not be possible to meet the requirement of "keeping the position of each test point consistent"
