Abstract
The utility model relates to a transformer oil passage insulating piece which is composed of two paper boards and a plurality of insulating supporting bars, wherein the paper boards and the insulating supporting bars are adhered in a hot pressing mode. The two paper boards are parallel to each other, the insulating supporting bars are perpendicular to the paper boards and two ends of each insulating supporting bar are adhered to the paper boards, and the insulating supporting bars are arranged in an equally spaced mode. The transformer oil passage insulating piece is characterized in that gaps are reserved between one end of each insulating supporting bar and the outer side face of each paper board, and the gaps between two adjacent insulating supporting bars and the outer side face of each paper board are respectively arranged in a dislocated mode. The transformer oil passage insulating piece is simple and reliable, convenient to manufacture, the gap is reserved between one end of each insulating supporting bar and the outer side face of one paper board, the phenomenon of oil passage blocking is reduced effectively, flowing of transformer oil is smooth, air cooling of a coil is ensured, performance stability of a transformer is guaranteed, and safe and reliable operation of the transformer in the process of smelting can be guaranteed.
Description
Technical field
The utility model relates to a kind of insulating component of transformer, especially relates to a kind of transformer oil passage insulating part.
Background technology
Along with expanding economy, the more and more large-scale change of smelting equipment transformer, also more and more higher to the requirement of transformer temperature rise.In the oil duct of transformer coil, transformer oil flows through, and takes away the heat that coil comes out, and coil temperature is reduced, guarantee that transformer can normally move use, transformer oil flows freely can directly not cause the variation of temperature, and transformer performance is worsened, and even burns the accidents such as coil.As shown in Figure 1, existing transformer oil passage insulating part by two cardboards 1 ' and some bar insulation stays 2 ' bonding hot pressing form, two cardboards 1 ' be arranged in parallel, some bar insulation stays 2 ' perpendicular to cardboard 1 ' setting and two ends be bonded in cardboard 1 ' on, insulating stay 2 ' two ends and two cardboards 1 ' the outside concordant.When the transformer oil passage insulating part is pressed on cross-over block and in the transformer running, very easily block two adjacent insulating stays 2 ' between oil duct, cause transformer oil to flow not smooth, coil temperature raises, the phenomenon that coil even occurs burning.
The utility model content
The applicant is for above-mentioned problem, be studied improvement, a kind of transformer oil passage insulating part is provided, simple and reliable for structure, easy to make, effectively reduce the oil duct choking phenomenon, transformer oil is flowed smooth and easy, guarantee cooling of coil, guarantee the stable performance of transformer, guarantee transformer operation safely and steadly in smelting.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of transformer oil passage insulating part, formed by two cardboards and the hot pressing of some bar insulation stays bonding, two described cardboards be arranged in parallel, some described insulating stay is bonded on cardboard perpendicular to cardboard setting and two ends, described insulating stay spaced set, leave the gap between one end of described insulating stay and the lateral surface of described cardboard, and the gap that consists of between the lateral surface of two adjacent bar insulation stays and described cardboard shifts to install respectively.
Further:
The width in described gap is between 5 ~ 15 millimeters.
The width in described gap is 10 millimeters.
Technique effect of the present utility model is:
The disclosed a kind of transformer oil passage insulating part of the utility model, simple and reliable for structure, easy to make, leave the gap between one end of every bar insulation stay and the lateral surface of cardboard, effectively reduce the oil duct choking phenomenon, transformer oil is flowed smooth and easy, guarantee cooling of coil, guarantee the stable performance of transformer, guarantee transformer operation safely and steadly in smelting.
Description of drawings
Fig. 1 is the structural representation of transformer oil passage insulating part in prior art.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the vertical view that Fig. 2 is.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
as Fig. 2, shown in 3, the utility model is formed by two cardboards 1 and the 2 bonding hot pressing of some bar insulation stays, cardboard 1 and insulating stay 2 are made by insulating board, the quantity of insulating stay 2 is determined according to actual needs, two cardboards 1 be arranged in parallel, some bar insulation stays 2 are bonded on cardboard 1 perpendicular to cardboard setting and two ends, strengthen bulk strength, insulating stay 2 spaced sets, leave gap 3 between one end of insulating stay 2 and the lateral surface of cardboard 1, and the gap 3 that consists of between two adjacent bar insulation stays 2 and the lateral surface of cardboard 1 shifts to install respectively, that is to say, the gap 3 that consists of between two adjacent bar insulation stays 2 and the lateral surface of cardboard 1 lays respectively on two cardboards 1.Usually between 5 ~ 15 millimeters, in the present embodiment, the width A in gap 3 is 10 millimeters to the width A in gap, and the spacing between two adjacent insulating stays 2 is 50 millimeters.
In use, insulating stay 2 is propped up certain space, and the gap of leaving 3 of each insulating stay 2 one ends, transformer oil can be flow through from the gap 3 of end, guarantee that oil duct is unobstructed, make oily stream take away the heat that coil comes out, reduce coil temperature, make the security of operation, stable of transformer.
Claims (3)
