Abstract
The utility model discloses a kind of novel transformer high and low pressure side folder connection structures, including draw screw rod and insulating sheath；Drawing screw rod includes outer drawing screw rod, interior drawing screw rod, other drawing screw rod；High-pressure side folder and the outer drawing screw rod of low-pressure side folder one end link, other end connection is interior to draw screw rod, and screw rod is drawn on two sides connection side；High-pressure side folder and low-pressure side folder are referred to as folder；Folder is equipped with through-hole, and screw rod is drawn to pass through folder through-hole, draws and is equipped with insulating sheath between screw rod and the contact surface of folder through-hole.The utility model be high and low pressure side folder is completely insulated, high and low pressure side folder is not at equipotential state, and supporting element is changed to draw screw rod, and drawings screw rod is un-conducted magnetic material, to reduce circulation, reduction leakage field bring added losses.Simultaneously by drawing the magnetic line of force of screw rod obviously fewer than supporting element, reduces leakage field area, in addition, supporting element is changed to draw screw rod, be more convenient processing and installation.
Description
Technical field
The utility model relates to a kind of novel transformer high and low pressure side folder connection structures, belong to transformer class product manufacturing
Technology.
Background technique
As increasingly fierceness, the price of product of power transformer product market competition largely play crucial work
With.Under the premise of guaranteeing property level, the design cost of product how is reduced, is the difficulty that each product manufacturing factory primarily solves
Topic.Traditional 110kV product structure high and low pressure side folder is connected by supporting element, and high and low pressure side folder keeps equipotential, winding
The leakage field of generation can generate biggish loss in folder supporting element.To increase product design costs.
Utility model content
Against the above deficiency, the utility model provides a kind of magnetic flux leakage that not only can solve winding generation, but also can reduce
The added losses of product reach the novel transformer high and low pressure side folder connection structure for reducing product design costs.This is practical new
Type changes traditional iron core folder fixed structure, using drawing screw-rod structure, and uses insulating sheath, thus reach reduction circulation,
The purpose for reducing leakage field bring added losses, improves the performance level of product.
In order to solve problem above, the utility model adopts the technical scheme that a kind of novel transformer high and low pressure side
Folder connection structure, which is characterized in that including drawing screw rod and insulating sheath；The drawing screw rod includes outer drawing screw rod, interior drawing spiral shell
Bar, other drawing screw rod；High-pressure side folder and the outer drawing screw rod of low-pressure side folder one end link, other end connection is interior to draw screw rod, and two sides connect
Connect other drawing screw rod；High-pressure side folder and low-pressure side folder are referred to as folder；Folder is equipped with through-hole, draws screw rod logical across folder
Hole draws and is equipped with insulating sheath between screw rod and the contact surface of folder through-hole,
As the another technical solution of the utility model, the place being connected on the drawing screw rod with folder is cased with insulation
Sheath.
As a preferred embodiment of the present invention, the drawing screw rod uses un-conducted magnetic material.
The utility model has the advantages that the utility model be high and low pressure side folder is completely insulated, high and low pressure side folder is not at equipotential
State, and supporting element is changed to draw screw rod, drawing screw rod is un-conducted magnetic material, to reduce circulation, reduces the additional damage of leakage field bring
Consumption.Simultaneously by drawing the magnetic line of force of screw rod obviously fewer than supporting element, reduces leakage field area, reduce stray loss.It is improved
Design, every stray loss reduces nearly 10kW after tested；In addition, supporting element is changed to draw screw rod, it is more convenient processing and installation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of novel transformer high and low pressure side folder connection structure.
Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Embodiment I: as shown in Figure 1, the utility model provides a kind of novel transformer high and low pressure side folder connection structure,
Including drawing screw rod and insulating sheath；The drawing screw rod includes outer drawing screw rod 1, interior drawing screw rod 2, other drawing screw rod 3；High-pressure side folder
4 and the link of 5 one end of low-pressure side folder is outer draws screw rod 1, screw rod 2 is drawn in other end connection, two sides connection is other to draw screw rod 3；High-pressure side
Folder 4 and low-pressure side folder 5 are referred to as folder；Folder is equipped with through-hole, and screw rod is drawn to pass through folder through-hole, draws screw rod and folder logical
Insulating sheath 6 is equipped between the contact surface in hole,
Embodiment II: the present embodiment and embodiment I the difference is that, the place being connected on the drawing screw rod with folder
It is cased with insulating sheath 6.
On the basis of the embodiment I or embodiment II, screw rod will be drawn to select un-conducted magnetic material, so that circulation is reduced,
Reduce leakage field bring added losses.
The drawing screw rod of the utility model facilitates processing, is thoroughly insulated high and low pressure side with insulating sheath, and leakage field area is reduced, ring
Stream and stray loss are reduced.
The above descriptions are merely preferred embodiments of the present invention, is not restricted to the utility model, for ability
For the technical staff in domain, various modifications and changes may be made to the present invention.It is all the spirit and principles of the utility model it
Interior, any modification, equivalent replacement, improvement and so on should be included within the scope of the claims of the utility model.
