Description
Technical field
This utility model relates to power equipment, specifically a kind of integrated resinous transformator.
Background technology
At present, the kind of transformator is a lot, has oil-filled transformer, dry-type transformer etc..Resin insulating dry type transformer, has the feature of its uniqueness, and since middle and late stage in last century, dry-type transformer worldwide develops rapidly.At present, along with the energy-conservation needs of power transformer, electricity consumption department constantly requires low-loss, high performance transformator, and resin insulating dry type transformer is widely used in city and skyscraper, stricter to energy-conservation and reliable requirement.But on resin transformator, owing to heat dispersion is limited, powerful transformator heat dissipation problem is problem demanding prompt solution.Sealed modular power source is typically with heat exchange pattern and dispels the heat, owing to inside modules casting glue generally cannot fully wrapped around transformator, and the thermal resistance of magnetic core of transformer is bigger, especially at the faying face of magnetic core, the bottom magnetic core temperature thus resulting in transformator patch substrate side is very big with the opposite side top temperature difference, needs to conduct to substrate top magnetic core heat.
Summary of the invention
The purpose of this utility model, it is simply that for solving the problem that prior art exists, and devise a kind of integrated resinous transformator, rational in infrastructure simply, improve the overall radiating effect of transformator.
The technical solution of the utility model is: a kind of integrated resinous transformator, including main body magnetic core, high pressure winding, low pressure winding, described main body magnetic core is arranged between upper and lower two substrates；The top of described upper substrate is provided with heat radiation aperture plate, and the side of described heat radiation aperture plate is provided with fan；The end of described high pressure winding and low pressure winding uses epoxy resin encapsulated solidified forming.
Being provided with psychrophore in described high pressure winding and low pressure winding, described psychrophore is made up of thermoplastic and is disposed in winding.
Described thermoplastic is polyester epoxy resin.
It is provided with thermal conducting material in described psychrophore.
Described upper substrate is provided with temperature sensor and temperature detect switch (TDS).
Described epoxy resin includes methyl tetrahydro phthalic anhydride and firming agent.
The beneficial effects of the utility model can be drawn by such scheme: owing to being connected with magnetic core by upper and lower base plate, can strengthen conduction of heat, is reliably achieved the heat radiation of the top magnetic core of transformator by simple structure.The top of upper substrate is provided with heat dissipating grid and fan, can strengthen the cross-ventilation of outside, such that it is able to effectively further improve the overall radiating effect of transformator.Being provided with psychrophore inside coil winding group, inside transformer heat can be made to be easier to derive, this programme has fire safety, heat dispersion height, reliability high.
As can be seen here, this utility model compared with prior art has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent from.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Wherein, 1 is fan, and 2 is heat radiation aperture plate, and 3 is upper substrate, and 4 is psychrophore, and 5 is low pressure winding, and 6 is high pressure winding.
Detailed description of the invention:
In order to be more fully understood that this utility model, explain in detail embodiment of the present utility model below in conjunction with the accompanying drawings.
Detailed description of the invention: as it is shown in figure 1, a kind of integrated resinous transformator, including main body magnetic core, high pressure winding 6, low pressure winding 5, described main body magnetic core is arranged between upper and lower two substrates；The top of described upper substrate 3 is provided with heat radiation aperture plate 2, and the side of described heat radiation aperture plate 2 is provided with fan 1；Described upper substrate 3 is provided with temperature sensor and temperature detect switch (TDS).The end of described high pressure winding 6 and low pressure winding 5 uses epoxy resin encapsulated solidified forming.Described epoxy resin includes methyl tetrahydro phthalic anhydride and firming agent.Being provided with psychrophore 4 in described high pressure winding 6 and low pressure winding 5, described psychrophore 4 is made up of thermoplastic and is disposed in winding.Described thermoplastic is polyester epoxy resin.It is provided with thermal conducting material in psychrophore 4.
Described above is not to restriction of the present utility model; this utility model is also not limited to the example above; change that those skilled in the art are made in essential scope of the present utility model, retrofit, add or replace, also should belong to protection domain of the present utility model.
