It can binding clip.
Background technique
Transformer plays an important role during operation of power networks in electric system.Wherein the high-potting of transformer is
The important means of transformer state is examined, the pilot project that can detect transformer includes Insulation test, D.C. resistance, dielectric loss
With capacitance, no-load voltage ratio etc..Each pilot project due to test principle difference, it is then different for the mode of connection.This needs basis
The instrument used is selected.Such as Insulation test is needed all to need three side casing of transformer to be shorted and be measured, D.C. resistance
It needs three side casing of transformer individually connecing p-wire and measure, first three side casing of transformer is carried out when dielectric loss is tested short
It connects and measures, also need to carry out independent measurement etc. to 110kV and the above high-pressure side casing.
From the point of view of above-mentioned test method, when replacing pilot project every time, require to re-start wiring.An and transformation
Device needs to carry out in interruption maintenance test of many times project, and every transformer power failure pilot project in this way need to repeatedly carry out transformation survey
It tries line.If all carrying out linear transformation when project of often carrying out a test, it is corresponding that testing crew also needs to remove wiring replacement
Instrument line and check the correctness of new test wiring, this process very big waste entire interruption maintenance time.In addition existing
Field requires personnel when transformation wiring every time and uses aerial platform since the height of transformer high-voltage bushing is higher
Carry out thread-changing operation.High altitude operation is carried out when converting for the wiring of bushing, this adds increased security risk, is unfavorable for controlling
The manufacturing time and site safety risk.A kind of binding clip for facilitating scene transformation wiring how is found, frequent changes are reduced
The security risk that the waste of wiring bring time and high altitude operation are brought, to greatly improve the operating efficiency at scene, reduction stops
The electric time meets now to the requirement of electrical stability, becomes a skill of urgent need to resolve during the examination of transformer interruption maintenance
Art problem.
Summary of the invention
In order to solve the above technical problem, the present invention provides power transformer high-potting multifunctional access wire clamps.This is more
Function binding clip has the advantages of test apparatuses a variety of suitable for transformer, while can be shorted on the ground, reduces more
Setting up time is changed, ascending operation-using safety risk is reduced, reduces power off time, improves working efficiency.
In order to achieve the object of the present invention, the invention adopts the following technical scheme:
Power transformer high-potting multifunctional access wire clamp, including shorting stub and for connecting transformer and tester

Further technical solution: the jaw of the vice jaw part is engaged in dentation and the jaw is equipped with and is convenient for and transformation
The recess that set Pipeline clip on device is connected.
Further technical solution: described lead wire one end is connect with the wiring point, and the lead wire other end is equipped with
The first metal connect-disconnect plug being connect with the test apparatus.
Further technical solution: the handle end is made of an auxiliary-handle, be respectively set in the handle wiring point with
And it is connect with wiring point and the lead wire from being extended to form to handle end in handle.
Further technical solution: the lead wire, shorting stub inner lead are copper conductor, the copper conductor lateral surface
Equipped with insulating protective layer.
The beneficial effects of the present invention are:
(1) for the present invention on the basis of conventional electric power transformation wiring, increasing can make a set of binding clip can with short connect function
It is applicable in Multitest project.Binding clip ontology connects two lead wires, can meet the need that transformer directly hinders pressure-wire and current line
It asks, while increasing by two short interfaces in a lead wire, realize short connect function for connecting shorting stub.Needing shorted transformer
When three-phase casing, binding clip that testing crew only needs that three are connected on bushing shell for transformer with two shorting stubs it is short
Interface is attached, and short connect function can be realized.
The step of needing replacing wiring the invention avoids different tests project, greatly reduces the time of field operation,
The time required to reducing power failure, power supply reliability is substantially increased.Transformer high-voltage bushing is since height is generally at 5-8 meters simultaneously
Left and right requires to carry out high altitude operation using aerial platform when replacing test connection every time, and the present invention can make to test people
Member's primary connection, meets test of many times demand, and operation of ascending a height is not had to when replacing pilot project, can complete wiring on ground and become
It changes, reduces ascending operation-using safety risk.
(2) jaw of jointing clamp of the present invention is dentation, is contacted This structure increases vice jaw part with transformer
Formedness, the recess on the jaw are configured according to the wire clamp size on transformer, are also avoided that while facilitating clamping
Jointing clamp falls off.In addition, the wiring point of the lead wire and jointing clamp, in the inside of jointing clamp handle end, which is reduced
Lead wire junction pulls in live use process, that is, ensure that not will cause in long-time service lead wire and wiring point it
Between occur falling off and loosen.
(3) connection of short interface of the present invention and shorting stub is connected using plug-in, facilitates the quick connection at scene, the gold
Belonging to elastic slice ensures that short interface contact reliably with shorting stub, while avoiding that appearance is traditional to be shorted and possibility using bare copper wire
Caused by poor contact consequence.In addition the connection of lead wire and test apparatus also uses plug-in to connect, which is suitable for
The connection request of transformer test instrument at present, while testing crew quickly can carry out replacement test apparatus on ground, simple side
Just.
