Abstract
The utility model discloses a lightning proof effect reaches 6kV's ethernet transformer, including stitch, gluey shell and transformer subassembly, the inside of gluing the shell sets up the transformer subassembly, and the stitch of gluing on the shell is connected to the transformer subassembly, glues the shell intussuseption and is filled with the filling material, and the first secondary coil's in the transformer subassembly interval is more than 10.0mm. Through the size structure of improving the transformer, coil material, embedment material and technology preparation make the network transformer can play the protection chip effect that 6kV was hit in the lightning protection, the enameled wire of this practicality through using this kind of high dielectric strength of 5 layers of insulated paint envelope curve for the chip can prevent by 6kV's thunderbolt.
Description
Technical field
The utility model relates to a kind of transformer, and specifically a kind of lightning protection effect reaches the Ethernet transformer of 6kV.
Background technology
For Ethernet; the protection of chip is only the protection of 2250VDC; and the protection of corresponding chip will be far longer than 2250V in practical application, need the network transformer of the lightning protection grade of 6kV or higher to do and isolate, so that the thunderbolt that chip suffers from from the Nature is in the application protected.Common network transformer can only meet the withstand voltage standard of 1500VAC.
Utility model content
The purpose of this utility model is the Ethernet transformer providing a kind of lightning protection effect to reach 6kV, to solve the problem proposed in above-mentioned background technology.For achieving the above object, the utility model provides following technical scheme: a kind of lightning protection effect reaches the Ethernet transformer of 6kV, comprise stitch, glue shell and transformer device, the inside of described glue shell arranges transformer device, transformer device connects the stitch on glue shell, be filled with fill material in glue shell, the spacing of the primary and secondary coil in transformer device is at more than 10.0mm.As further program of the utility model: the insulated wire in transformer device is 5 layers of enamel insulated wire.Compared with prior art, the beneficial effects of the utility model are: by improving the dimensional structure of transformer, coil method, and Embedding Material and technique make and makes network transformer can play the protect IC effect of anti-lightning strike 6kV; This practicality, by the enamelled wire of use 5 layers of this high insulation resistance of enamel insulated wire, makes chip can prevent by the thunderbolt of 6kV.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1; in the utility model embodiment; a kind of lightning protection effect reaches the Ethernet transformer of 6kV; comprise stitch 2, glue shell 3 and transformer device 4; the inside of described glue shell 3 arranges transformer device 4; transformer device 4 connects the stitch 2 on glue shell 3; fill material 1 is filled with in glue shell 3; thus transformer device 4 sealing is fixed in glue shell 3; the whole casting glue of glue shell 3 internal clearance is filled out and is rushed isolation material to protect the magnetic core of transformer, and causes jumping arc by exposed section when exposed copper cash avoids exposed part to be struck by lightning.
For preventing thunderbolt from producing electric arc because spacing is inadequate, at more than 10.0mm, there is protect IC to avoid electric arc in the spacing of the primary and secondary coil in transformer device 4.Insulated wire in transformer device 4 is 5 layers of enamel insulated wire, expands the spacing of primary and secondary coil, carries out double shielding, re-use the appearance that full dosing technology improves electric arc, to reach the effect of 6kV lightning protection chip to the coil of transformer device 4.
In transformer device 4, transformer coil makes and avoids hard object to damage coat of paint film, carries out coating protect in advance before assembling to transformer coil; Secondary potting protection is carried out again after assembling.
By improving the dimensional structure of transformer, coil method, Embedding Material and technique make and make network transformer can play the protect IC effect of anti-lightning strike 6kV; The enamelled wire of high insulation resistance to be used implement and all electrical parameters of network transformer also will meet the requirement of IEEE802.3 in this network transformer, and can prevent by the thunderbolt of 6kV by protect IC.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
