The utility model purpose is to provide a kind of local discharge detection device, to solve the technical matters that influenced by external factor when the Partial Discharge Detection.
For realizing above-mentioned purpose, the utility model provides a kind of local discharge detection device, comprises detecting unit, comprises sensor and the transmission line that is connected with sensor; Mask tape, mask tape are arranged on around the device to be measured, and device to be measured and sensor are surrounded; The mask tape is provided with opening, and transmission line passes opening.
Further, local discharge detection device also comprises the connection fixed bin, connects fixed bin and is arranged on opening part, and sensor is arranged on and connects in the fixed bin, and transmission line passes the connection fixed bin.
Further, connecting fixed bin removably is connected with device to be measured.
Further, the outer wall of mask tape and device to be measured fits tightly.
Further, the mask tape is fixedly connected with device to be measured.
Further, the mask tape removably is connected with device to be measured.
Further, mask tape and device to be measured pass through adhesive tape bonding.
Further, opening is a cross bath.
The utlity model has following beneficial effect:
Local discharge detection device adopts the mask tape effectively to solve the interference of shielding external signal, in time finds the GIS inherent vice, shortens the time that defective is searched, and improves the accuracy of test.
Except top described purpose, feature and advantage, the utility model also has other purpose, feature and advantage.To do further detailed explanation to the utility model with reference to figure below.
