Description
Technical field
The utility model belongs to transformer technology field, and in particular to a kind of to have low turn in pulse simulation network
The transformer of coefficient is moved, can be installed in shift frequency half wave track circuit system thunder defending simulation network disk has lightning protection isolation features
Transformer.
Background technology
Existing pulse simulation network transformer uses c-type iron core, and impact transfer ratio is≤1/100, it is impossible to meet lightning protection
Transformer impacts the requirement of transfer ratio≤1/500, and existing pulse simulation network transformer efficiency is low, and volume is big, it is impossible to
Meet the correlated performance structure design of lightning protection simulation network disk.
This pulse simulation network transformer is mounted in pulse simulation network disk, than the pulse simulation of existing version
Network transformer is by higher lightning protection effect and ability.
Utility model content
The purpose of this utility model is：A kind of pulse simulation network transformer of low transfer ratio is provided, can reliably be pacified
The transformer with lightning protection isolation features in shift frequency pulse circuit system lightning protection simulation network disk is attached to, so as to solve existing skill
The problem of in art.
The utility model is achieved by the following technical solution：A kind of pulse simulation network transformation of low transfer ratio
Device, it is characterised in that：Including 2 O-shaped iron cores and the I shaped iron cores being clipped in the middle of 2 O-shaped iron cores, around wired on I shaped iron cores
Circle, leaves a blank tape between coil border and iron core edge；The coil include primary and secondary winding, primary and secondary winding it
Between provided with electrostatic screen layer.
Further：The electrostatic screen layer ground connection.
Further：In the O-shaped iron core and I shaped iron cores pass through it is clamping fixed energetically.
Further：The O-shaped iron core and I shaped iron core glue are cased, primary and secondary winding and the electrostatic screen layer
Lead is connected with the binding post on housing.
The beneficial effects of the utility model are：1st, the utility model structure has selected O, I shaped iron core, effectively reduces equipment
Size simultaneously improves lightning protection isolating power；2nd, electrostatic screen layer is added between primary and secondary winding, transfer ratio is effectively reduced；
3rd, coil border is respectively retracted 4mm-6mm during coiling on I shaped iron cores, increases climbing arc distance, improves lightning protection isolating power.
Brief description of the drawings
Fig. 1 is circuit composition schematic diagram of the present utility model；
Fig. 2 is the utility model inner-core structural representation；
Fig. 3 is the utility model overall structure diagram；
Number explanation in figure：1 be coil, 2 be O-shaped iron core, 3 be I shaped iron cores, 4 be blank tape, 5 be electrostatic screen layer, 6
It is binding post for shell, 7.
Embodiment
It is a kind of pulse simulation network transformer of low transfer ratio of the utility model as Figure 1-3, its feature exists
In：Including 2 O-shaped iron cores 2 and the I shaped iron cores 3 being clipped in the middle of 2 O-shaped iron cores, coil 1, coil side are wound with I shaped iron cores
A blank tape 4 is left between boundary and iron core edge；The coil includes armature winding 11, secondary windings 12, in primary and secondary winding
Between provided with electrostatic screen layer 5.Iron core is improved to after O, I shaped iron core, improvement structure in lightening pulse invasive system in this structure
When, because magnetic circuit corner becomes many, energy is largely consumed by transformer, therefore the impact caused is greatly reduced.Simultaneously primary and secondary
Provided with electrostatic screen layer between winding, the coupling distance of primary and secondary is increased, coupled capacitor is reduced, considerably increases thunder
The ability of electric pulse protection isolation, transfer ratio≤1/500, meets and requires after tested.
It is preferred that：The blank bandwidth is 4mm-6mm.
It is preferred that：The electrostatic screen layer ground connection；The electrostatic screen layer is copper foil.
It is preferred that：It is clamping fixed energetically that the O-shaped iron core and I shaped iron cores pass through.
It is preferred that：The O-shaped iron core and I shaped iron cores mucilage binding are in shell 6, primary and secondary winding and the electrostatic screen layer
Lead is connected with the binding post 7 on housing.
By the improved transformer of this programme, size reduction is 73mm × 93mm × 11.2mm, and transfer ratio is less than 1/500,
Meet and require.
