Description
Technical field
The utility model is related to nuclear power generator rotor electrical test joints.
Background technology
The conducting surface of nuclear power generator rotor is a plane, positive and negative polarities respectively by two planar conductor plates with encourage
Magnetomechanical connects, and is connected by fixing bolt between electrode and planar conductor plates.It carrying out generator amature D.C. resistance, handing over
When the work such as flow impedance, measurement insulation, rotor is imported for electric current will be measured, the conductive plate of rotor can be dismantled, measurement clip
It is clipped on fixing bolt, since fixing bolt is used as the installation part of electrode and conductive plate originally, material is carbon steel, electric
Resistance is higher, screw thread flow test electric current is only leaned on when its underpart does not have conductive plate, contact resistance is big, caused additional measurement error
Greatly.In addition, its screw thread or nut clip test clip are easy to fall off, experiment process is not safe enough.
Invention content
The technical problem to be solved by the present invention is to provide a kind of improved nuclear power generator rotor electrical experiment and connect
Head.
Technical solution adopted by the utility model to solve its technical problems is：Nuclear power generator rotor electrical test joint
Part, the test joint part include screw rod shaft, pole cap and connector rod, and the screw rod shaft is connected to the inner surface of pole cap,
The screw rod shaft and the screw hole Corresponding matching for installing conductive plate on rotor electrode, to realize when screw rod shaft is screwed into screw hole
Shi Suoshu pole caps are bonded with rotor electrode；The connector rod is connected to the outer surface of pole cap and is connected to be pressed from both sides with electric measurement.
Foregoing nuclear power generator rotor electrical test joint part, the connector rod is perpendicular to the pole cap appearance
Face, and the radial dimension of connector rod is less than the pole cap.
Foregoing nuclear power generator rotor electrical test joint part is equipped with axial prolong along the outside wall surface of the connector rod
The groove stretched.
The material of foregoing nuclear power generator rotor electrical test joint part, the test joint part is copper.
Foregoing nuclear power generator rotor electrical test joint part, the pole cap are hexagonal.
Implement the technical solution of the utility model, at least there is advantageous effect below：Improved electrical test connector
Its screw rod shaft of part has substantially completely been screwed into screw hole, and pole cap is made to be directly fitted with rotor electrode, and the two contact area becomes larger, and reduces
Contact resistance reduces measurement error；In addition setting connector rod connects to be pressed from both sides with measurement.
Description of the drawings
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing：
Fig. 1 is the utility model prior-art illustration；
Fig. 2 is utility model diagram；
Mark is described as follows in figure：
1, electrical test adapter piece；10, screw rod shaft；11, pole cap；12, connector rod；100, nut；101, gap；102、
Screw rod.
Specific implementation mode
For a clearer understanding of the technical features, objectives and effects of the utility model, now control attached drawing is detailed
Illustrate specific embodiment of the present utility model.
The electrode that "+,-" indicates rotor as shown in Figure 1, in figure, carry out generator amature D.C. resistance, AC impedance,
When measuring the work such as insulation, need first remove conductive plate from electrode, then be screwed into and be originally used for conductive plate connecting with electrode
Fixing bolt causes a part of screw rod 10 of fixing bolt can be exposed due to the omission of conductive plate, nut 100 not with electrode paste
It closes, when nut 100 or exposed screw rod 10 are clamped in electric measurement, only leans on the screw thread flow test electric current of screw rod 10, contact
Resistance is big, and caused additional measurement error is big.And measure that gripping for folder is also very inconvenient, and general nut 100 is compared with disaster
With clamping, clamping stability is poor, and exposed half of screw 10 is clamped if be selected in, since the gap 101 at this is in spiral shell
Between cap 100 and electrode, interfered by two structures, it is difficult to carry out clipping operation.
Nuclear power generator rotor electrical test joint part 1 as shown in Figure 2, it is characterised in that：The test joint part packet
Screw rod shaft 10, pole cap 11 and connector rod 12 are included, the screw rod shaft 10 is connected to the inner surface of pole cap 11, the screw rod bar
Body 10 and the screw hole Corresponding matching for installing conductive plate on rotor electrode, described in realizing when screw rod shaft 10 is screwed into screw hole
Pole cap 11 is bonded with rotor electrode；The connector rod 12 is connected to the outer surface of pole cap 11 and is connected to be pressed from both sides with electric measurement.
The screw rod shaft 10 of adapter piece is fully screwed into screw hole until its pole cap 11 is bonded with electrode, pole cap 11 effectively increases
Add the conductive contact area with electrode, contact resistance to become smaller, reduces measurement error.And the connector in 11 outer surface of pole cap is set
Bar 12 reduces the interference between structure, convenient for measuring the installation of folder.
In some embodiments, connector rod 12 is perpendicular to 11 outer surface of the pole cap, and the radial dimension of connector rod 12 is less than
The pole cap 11.Connector rod 12 can generally be arranged to flat by relatively fine connector rod 12 to measure folder clamping.Can along institute
Axially extending groove is arranged in the outside wall surface for stating connector rod 12, and the clamping stability between folder can be reinforced and be measured to groove.
1 material of this case electrical test adapter piece preferably uses copper, and electric conductivity is superior, and pole cap 11 is preferably hexagonal,
Convenient for force.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, the utility model can have various changes, combination and variation.It is all the utility model spirit and
Within principle, any modification, equivalent replacement, improvement and so on, should be included in the utility model right it
It is interior.
