Description
Technical field
The utility model relates to shell protection technique field, specially a kind of new transformer shell.
Background technique
Mutual inductor is the general designation of current transformer and voltage transformer, high voltage is become low-voltage, high current becomes small
Electric current, wherein the effect of current transformer be can the biggish primary current of numerical value by certain no-load voltage ratio be converted to numerical value compared with
Small secondary current, for the purposes such as being protected, being measured, current transformer can to the instrument for needing to connect ammeter etc and after
Electricity, which carries out protective effect, will pass through mutual inductance because each instrument can not connect on actual value very big conducting wire or bus
Device is converted into lesser two sub-value of numerical value, primary actual value is being reflected by no-load voltage ratio, current transformer is as exchange
Current signal acquisition elements can generally be matched with products such as multi-loop current monitoring device, breaker of plastic casing, existing mutual
Sensor PIN foot is exposed outside, is easy to cause short circuit, causes to cause periphery component damage, for this purpose, we have proposed one kind
New transformer shell.
Utility model content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of new transformer shell
Existing mutual inductor PIN foot is exposed outside, is easy to cause short circuit, leads to the problem of causing damage parts.
To achieve the above object, the utility model provides the following technical solutions: a kind of new transformer shell, including mutual inductance
The left and right sides middle part of device, PIN foot, leading foot, external slot, epoxy resin layer, the mutual inductor is respectively provided with the PIN foot, institute
It states the top and the bottom at left and right sides of mutual inductor and is respectively provided with the leading foot, the outside is respectively connected at left and right sides of the mutual inductor
The inside of slot, the external slot is filled with the epoxy resin layer, and the PIN foot and the leading foot are respectively positioned on the epoxy
The inside of resin layer.
Preferably, the external slot is polyethylene material.
Preferably, the height of the external slot is lower than the side wall of the mutual inductor.
Preferably, the epoxy resin layer is linear aliphatic epoxy resin layer.
Compared with prior art, the utility model has the beneficial effects that this kind of transformer casing, in the left and right sides, connection is outer
Portion's slot, by epoxy resin layer on lumen loading, entire PIN foot is integrally covered package, also functioned to leading foot by epoxy resin layer
Protective effect, keeps mutual inductor ontology and periphery component completely isolated, prevents security risk.
Detailed description of the invention

Fig. 3 is the utility model bottom upward sectional view.
In figure: 1 mutual inductor, 2 PIN foot, 3 leading foots, 4 external slots, 5 epoxy resin layers.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of new transformer shell, keeps mutual inductor ontology and periphery component completely isolated, Du
Exhausted security risk please refers to Fig. 1-3, including mutual inductor 1, PIN foot 2, leading foot 3, external slot 4, epoxy resin layer 5, mutual inductor 1
The left and right sides in the middle part of be respectively provided with PIN foot 2, the top and the bottom of 1 left and right sides of mutual inductor are respectively provided with leading foot 3, the left and right of mutual inductor 1
Two sides are respectively connected with external slot 4, and by being connected with external slot 4 in the left and right sides of mutual inductor 1, and the inside of portion's slot 4 is filled with
Epoxy resin layer 5, and PIN foot 2 and leading foot 3 are respectively positioned on the inside of epoxy resin layer 5, by epoxy on 4 lumen loading of external slot
The whole covering package of entire PIN foot 2 is also carried out whole covering package to leading foot 3, makes mutual inductance by resin layer, epoxy resin layer
1 ontology of device and periphery component are completely isolated, prevent security risk.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
