Transformer is a kind of static electrical equipment, and it utilizes electromagnetic induction principle by a kind of AC energy of voltage class
It is transformed into the AC energy of another voltage class, main function of the transformer in power system is voltage of transformation, in favor of
Power transmission.Transformer can be divided into dry-type transformer and oil-filled transformer by the type of cooling, and oil-filled transformer is mainly by device
Body, fuel tank, cooling device, protection device and outgoing line device are constituted, and wherein device body includes cored, coil, insulating part and lead,
Coil is around the home on iron core, and lead includes high pressure lead-in, low pressure lead-out wire and zero line.The low pressure of current common transformer is drawn
Outlet and zero line are typically mounted at position close to each other, cause it inconvenient when mounted, while giving the operation such as maintenance
Also very big inconvenience is brought, and occupies installing space, the volume of transformer is increased.Insulating part is usually that pad is put in the upper of coil
Lower two ends, are insulated and support compression to coil.Common insulating part is generally tabular at present, and the insulating part of this shape
Heat dispersion is poor, and adds the usage amount of insulating part raw material, and also poor to the support compression effect of coil.
Utility model content
The purpose of this utility model is exactly to provide a kind of rationally distributed in order to solve above-mentioned deficiency, quite convenient for low pressure
The installation and maintenance of lead-out wire, ventilation and heat performance are good, can reduce the transformer New Low Voltage of cross-over block raw material usage amount
Winding leading-out wire structure.
The technical solution that in order to solve the above-mentioned technical problem the utility model uses is as follows：
Transformer New Low Voltage winding leading-out wire structure, it include upper bracket, lower carriage, paired insulation support plate,
Low pressure lead-out wire, zero line and coil, it also includes insulator foot, cross-over block and copper bar, and the coil is interposed in paired
Between insulation support plate, the cross-over block is padded respectively to be put between coil and paired insulation support plate, and the cross-over block is in
Long cube is block, and is intervally arranged in row, and the upper bracket and lower carriage are interposed on the outside of paired insulation support plate respectively,
Corresponding mounting hole is offered on the upper bracket and lower carriage respectively, screw rod has been placed in the mounting hole, on the screw rod
Rotation is equipped with nut, paired insulation support plate, cross-over block and coil lock is put between upper bracket and lower carriage, the insulation
Base is fixedly mounted on upper bracket, and one end of the low pressure lead-out wire is respectively and fixedly installed on the insulator foot, the other end
Electrically connected respectively with coil, insulation board be installed on the lower carriage, the copper installation on the insulation board, the zero line
One end is separately mounted on the copper bar, and the other end is electrically connected with coil respectively, and leading-out terminal is provided with the copper bar.
The insulator foot is made up of paired clamping plate, the upper end of the low pressure lead-out wire be interposed in the paired clamping plate it
Between, corresponding hole is offered on the upper bracket and paired clamping plate, bolt has been placed in the hole, revolves and puts on the bolt
There is nut, by paired Boards wall on upper bracket, and the upper end lock of low pressure lead-out wire is put between paired clamping plate.
The beneficial effect that the utility model can be reached using above-mentioned technical solution is：By low pressure lead-out wire and zero line
The both sides up and down of coil are separately mounted to, its arranged apart may be such that its layout becomes extremely to simplify rationally so that low pressure is drawn
The operation such as outlet and the installation of zero line and maintenance becomes very convenient.It is in long cube that the plate-like insulating part of tradition, which is arranged to,
Block cross-over block, so as to greatly reduce the usage amount of insulating part raw material, effectively reduces the production cost of transformer,
The weight of transformer is alleviated, and good support compression effect is played to transformer coil, the cross-over block is in row interval row
Cloth so that form air channel between adjacent cross-over block, substantially increases the result of ventilating heat dissipation of transformer coil.
