Description
Technical field
The utility model relates to transformer technology field more particularly to a kind of transformer device structures for ammeter collector.
Background technique
Isolating transformer refers to input winding and output winding in the transformer being electrically isolated from each other, with to avoid accidental
Simultaneously touch electrical body (or due to insulation damages may electrification metal parts) and the earth brought by danger, its principle and
Common dry-type transformer is identical, and main that primary power source circuit is isolated also with electromagnetic induction principle, secondary circuit floats over the ground
Sky, to guarantee Electrical Safety.
In high-tension circuit module, as the isolating transformer used on ammeter collector need to meet the resistance to of primary and secondary 6000V
Pressure, however as common EE13 skeleton structure, primary and secondary winding can only meet 4000V or so pressure resistance in same winding slot, reach
Barricade and casing are needed plus carried secretly to the resistance to pressure request of 6000V, since entrainment barricade need to account for part winding space, lead to line packet mistake
Greatly, product can not produce.
Utility model content
The purpose of this utility model is to provide a kind of transformer device structures for ammeter collector, overcome the prior art
Deficiency improves the high-voltage resistance capability of transformer, improves isolation effect, meets the safety requirements of ammeter collector.
In order to achieve the above object, the utility model uses following technical scheme:
A kind of transformer device structure for ammeter collector comprising skeleton and coiling group, coiling group are wound on skeleton, bone
The two sides of the bottom of frame are provided with hermetic terminal, and several draw pins are provided on hermetic terminal, and draw pin is connect with coiling group, wherein bone
Frame is horizontal-type skeleton, and coiling group includes the first winding and the second winding, is provided with baffle on skeleton, forms two winding slots, the
One winding, the second winding are set in corresponding winding slot, and the bottom of baffle is arranged beyond the end face of hermetic terminal, and insertion pin guiding
Fixed support is formed in connector, is wound with insulating tape outside the first winding and the second winding.By increasing the length of baffle, increase
Creepage distance between winding.
Particularly, draw pin connector is pcb board, and the draw pin that two sides are corresponded on pcb board is provided with pad, is corresponded on pcb board
Baffle offers fixing groove, and the baffle for being inserted into fixing groove separates the pad of two sides.Effectively increase creepage distance.
Particularly, coiling group has multiple, and baffle more than one, two neighboring winding is separated with baffle.
Particularly, the top of baffle is arranged without departing from the edge plane of skeleton.Good appearance degree is not influenced.
To sum up, the beneficial effects of the utility model are, compared with prior art, the transformer for ammeter collector
Skeleton is divided into several winding slots according to coiling area needed for each winding, by baffle by structure, to make to have between each winding
Effect isolation, and can be by changing creepage distance and high pressure resistant intensity between the length of baffle, thickness control winding, structure
Simply, it is effectively utilized winding space, isolation effect is good, meets the safety requirements of ammeter collector.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the transformer device structure provided by the embodiment of the utility model for ammeter collector；
Fig. 2 is the coiling schematic diagram of the transformer device structure provided by the embodiment of the utility model for ammeter collector.
Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
It please refers to shown in Fig. 1 and 2, the present embodiment provides a kind of transformer device structures for ammeter collector, mainly include
Skeleton 1 and coiling group, coiling group are wound on skeleton 1, and the two sides of the bottom of skeleton 1 are provided with hermetic terminal 2, are set on hermetic terminal 2
Several draw pins 3 are equipped with, draw pin 3 is connect with coiling group, and skeleton 1 is horizontal-type skeleton, and coiling group is shown in the present embodiment with two windings
Example, respectively the first winding 4 and the second winding 5 are provided with baffle 6 on skeleton 1, form two winding slots 7, the first winding 4, the
Two windings 5 are set in corresponding winding slot 7, and the bottom 61 of baffle 6 is arranged beyond the end face of hermetic terminal 2, are inserted with the transformer
The draw pin 3 that two sides are corresponded on pcb board, on pcb board is provided with pad, and baffle 6 is corresponded on pcb board and offers fixing groove,
While draw pin 3 is inserted into pad, baffle 6 is inserted into fixing groove, so that the pad of two sides be separated, effectively increase climb electricity away from
From the stability of mounting structure can be improved while increasing isolation effect, the top 62 of baffle 6 can not in order to not influence beauty
Insulating tape 8 is wound with outside edge plane setting beyond skeleton 1, the first winding 4 and the second winding 5.
It should be noted that the length of baffle 6 determines the creepage distance between winding, and the thickness of baffle 6 determines
High pressure resistant intensity.
In order to convenient for production, it can be directed to certain resistance to pressure request custom transformer structure, baffle 6 and skeleton 1 are integrally formed.And
