Abstract
The utility model discloses a sleeve pipe end screen connecting device for transformer partial discharge test, including spring leaf, drum, connecting wire and measuring impedance connector, the drum is used for connecting the sleeve pipe end screen of transformer, and the internal diameter of drum is not less than the sleeve pipe end screen external diameter of transformer, and the spring leaf sets up in the drum and is used for clamp sleeve end screen, detects the impedance connector and passes through the connecting wire to connect the drum terminal to be used for being connected to detection impedance input. The technical effects of the utility model comprises, can reliably connect transformer bushing end screen and detect the impedance through this device, can avoid partial discharge test in -process sleeve pipe end screen lost territory, damage the sleeve pipe, also can reduce measurement circuit simultaneously and disturb, accuracy that improvement office was high -volume detected reduces transformer partial discharge test wiring complexity, improves work efficiency.
Description
Technical field
This utility model relates to a kind of bottom shielding of bushing attachment means for Existing during Partial Discharge Test for Transformer.
Background technology
Shelf depreciation defect is the root of many transformer faults, uses pulse current method measuring transformer office
Portion's discharge capacity is the effective means finding inside transformer defect, and the method is Transformer Plant Test, friendship
Connect test must do project.But, during Existing during Partial Discharge Test for Transformer, special owing to not having
Bottom shielding of bushing is connected by attachment means with detection impedance, generally uses typical clamp to clamp, folder often occurs
Sub-folder is the most insecure or loose contact, occurs that bottom shielding of bushing lost territory is damaged sleeve pipe and disturbed excessive with measuring loop
Affect office's accuracy high-volume.
Summary of the invention
It is not exclusively used in the device of connection detection impedance in order to solve current Transformer Bushing Tap, causes inspection
Surveying the technical problem that accuracy is not enough, this utility model provides one can be reliably connected bushing shell for transformer end
Screen and detection impedance, it is to avoid bottom shielding of bushing lost territory during partial discharge test, damage sleeve pipe；Can subtract
Measure loop interference, the set for Existing during Partial Discharge Test for Transformer of the accuracy that raising office is high-volume detected less
Pipe end shield attachment means.
In order to realize above-mentioned technical purpose, the technical solution of the utility model is, a kind of for transformer partial
The bottom shielding of bushing attachment means of portion's discharge test, including spring leaf, cylinder, connecting line and detection impedance even
Joint, described cylinder is for the bottom shielding of bushing of connection transformer, and the internal diameter of cylinder is not less than transformator
Bottom shielding of bushing external diameter, described spring leaf is arranged in cylinder and for clamp sleeve end shield, described
Detection impedance union joint connects cylinder ends by connecting line, and is used for being connected to detect impedance input.
Described a kind of bottom shielding of bushing attachment means for Existing during Partial Discharge Test for Transformer, also includes insulation
Oversheath, described insulating outer protective cover is arranged on cylinder outer wall.
Described a kind of bottom shielding of bushing attachment means for Existing during Partial Discharge Test for Transformer, described spring
Sheet, cylinder are made by metallic copper, and described connecting line is plain conductor.
Of the present utility model have technical effect that, Transformer Bushing Tap can be reliably connected by this device
With detection impedance, bottom shielding of bushing lost territory during partial discharge test can be avoided, damage sleeve pipe, simultaneously
It also is able to reduce and measures loop interference, the accuracy that raising office is high-volume detected, reduce partial discharge of transformer
Test connection complexity, improves work efficiency.
The utility model is described in further detail below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Wherein, 1 is spring leaf, and 2 is insulating outer protective cover, and 3 is cylinder, and 4 is connecting line, and 5 is detection resistance
Anti-union joint.
Detailed description of the invention
Seeing Fig. 1, the present embodiment includes spring leaf, cylinder, connecting line and detection impedance union joint, cylinder
For the bottom shielding of bushing of connection transformer, and the internal diameter of cylinder is not less than the bottom shielding of bushing external diameter of transformator,
In spring leaf is arranged at cylinder and for clamp sleeve end shield, detection impedance union joint is connected by connecting line
Cylinder ends, and be used for being connected to detect impedance input.
Further, for the ease of operating time actually used, the present embodiment also includes insulating outer protective cover, absolutely
Edge oversheath is arranged on cylinder outer wall.
In order to ensure the accuracy of detection, spring leaf, cylinder are made by metallic copper, and connecting line is metal
Wire.
The simple in construction of the present embodiment, and easily fabricated, wherein spring leaf, cylinder are connected with detection impedance
Head can be in the customization of gold utensil equipment factory；Insulating outer protective cover can customize at plastics maker；Connecting line can use general
Live wire.
Time actually used, first detection impedance union joint is connected with detection impedance input, spring leaf 1,
Insulating outer protective cover, cylinder insert bottom shielding of bushing junction, and spring leaf plays clamp sleeve end shield effect, makes
Obtaining it to be reliably connected with bottom shielding of bushing, insulating outer protective cover plays insulating effect so that attachment means and sleeve pipe
End shield surrounding metal is isolated.
