Description
Technical field
Technical field of transformer manufacturing is the utility model is related to, more particularly to a kind of transformer low voltage cable connection structure.
Background technology
General requirement has lead-out wire extraction in oil-filled transformer low-pressure side at present and lead-out wire is connected with external cable,
And existing low voltage side cable wiring construction generally use low-pressure side lead-out wire is connected with connect-disconnect plug, connect-disconnect plug and cable connector,
And connect-disconnect plug is arranged on inside oil tank of transformer.The shortcomings that this wiring construction, is because connect-disconnect plug is arranged in transformer
Portion, the installation quality of connect-disconnect plug tie point can not judge and ensure have the hidden danger of transformer oil seepage at connect-disconnect plug；While by
In the design feature for the transformer for being provided with connect-disconnect plug, electricity need to be connected on connect-disconnect plug when carrying out preventive trial to transformer
Cable etc., then be connected with special test casing, it can just do experiment, it is therefore desirable to purchase special test casing.Tested
When, the end for connecting connect-disconnect plug is extracted, then end insertion Special test sleeve pipe is tested.This test method is not only
Need special expense to purchase test casing, simultaneously because dismounting difficulty is big, on installation test casing and reconnection, also need phase
Answer extension device power off time.
Therefore, oil-filled transformer needs a kind of new cable connection structure to solve the above problems.
Utility model content
This application discloses a kind of transformer low voltage cable connection structure, lead-out wire draws on achievable step down side
Go out and connect, ensure the oily ne-leakage in oil tank of transformer.
To achieve the above object, this application provides a kind of transformer low voltage cable connection structure, including：
The bushing shell for transformer passed through in oil-filled transformer low-pressure side for step down side lead-out wire；
Cable；
First end is connected with the bushing shell for transformer and the bushing shell for transformer inside lead, the second end and the cable
The conducting copper of one end connection.
Preferably, the bushing shell for transformer is arranged on the rise seat of oil-filled transformer low-pressure side.
Preferably, in addition to by the bushing shell for transformer, the cable and the conducting copper cable box covered.
Preferably, it is characterised in that also include being connected with the conducting copper and be fixed on the conducting copper described
Insulator on cable box.
Preferably, it is characterised in that also include the fixing device being fixed on the cable on oil-filled transformer.
Preferably, it is characterised in that the fixing device includes：
The fixed plate being fixedly connected with oil-filled transformer；
It is arranged on the through hole passed through in the fixed plate for the cable.
Transformer low voltage cable connection structure provided by the utility model, mainly including bushing shell for transformer, cable and conduction
Copper bar.It is simple in construction by bushing shell for transformer and conducting copper by the lead-out wire and cable connection of step down side, and by
It is not disposed in transformer low voltage cable connection structure on fuel tank, therefore leakage problems is not present；Meanwhile the utility model is becoming
Bushing shell for transformer is set in depressor low-pressure side, the devices such as cable are not installed in shop test, it is not necessary to designs special experiment dress
Put, reduce testing expenses, operation is simpler, conveniently.
Certainly, any product for implementing the application it is not absolutely required to reach all the above advantage simultaneously.
