Description
Technical field
The utility model relates to transformer technical fields, and in particular to a kind of combination transformer.
Background technique
Currently, cast-type combination transformer is the electrical energy measurement on electrical grid transmission route, and play Current Voltage survey
The effect of amount and monitoring.Existing cast-type combination transformer is since its internal structure design is unreasonable, potential winding and electric current
The spacing of coil is too small, when using poured with epoxy resin, the epoxy resin layer of combination transformer casting it is in uneven thickness,
Cause epoxy resin layer easy to crack, so that the combination transformer haves the defects that insulation performance is poor, performance is unstable, partial discharge is high.
Summary of the invention
The purpose of the utility model is to overcome the defect of the prior art, provide a kind of structure it is simple, it is stable and reliable for performance,
The combination transformer of good insulation preformance.
To achieve the above object, the utility model uses a kind of combination transformer, including epoxy resin poured body, pressure-wire
Coil assembly, current coil component, the support component being arranged between potential winding component and current coil component, the voltage
Coil block includes two voltage iron cores, two potential windings being separately positioned on each voltage iron core, the current coil
Component includes two current ferric cores, two current coils being separately positioned on each current ferric core, and the support component includes
The first clamping plate being arranged on the lower end surface of two voltage iron cores, the second folder being arranged on the upper surface of two voltage iron cores
Plate, the third clamping plate positioned at the surface of second clamping plate, are connected with multiple supports between the second clamping plate and third clamping plate
Bar is respectively arranged with a supporting element at corresponding two current coils on the third clamping plate, is respectively set on each supporting element
There is the arc clamping part contradicted on current coil periphery wall.
The beneficial effect of above structure is: the combination transformer simple, stable and reliable for performance, good insulation preformance with structure
The advantages of, the support component of the combination transformer uses double layer support structure, and second clamping plate, third clamping plate can be by current lines
Circle pouring position is fixed, and ensure that the insulation spacing between current coil and potential winding, and in casting epoxy resin, epoxy
Resin-cast material can be completely into current coil, inside potential winding, to ensure that the thickness of the epoxy resin layer of casting
Degree uniformly, avoids cracking caused by epoxy resin layer thickness unevenness, to improve the finished product of the manufacture of the combination transformer
Rate also improves the dielectric strength of epoxy resin poured body, so that the partial discharge quantity of the combination transformer can reach country
Standard greatly prolongs the service life of entire combination transformer.
Particularly, the first clamping plate, second clamping plate pass through adhesive tape respectively and are fixedly connected with two voltage iron cores.First
Clamping plate, second clamping plate are fixed on two voltage iron cores by adhesive tape, consequently facilitating first clamping plate, second clamping plate and two voltages
The assembling of iron core.
Detailed description of the invention
Fig. 1 is the utility model embodiment internal structure chart.
Fig. 2 is the assembly structure diagram of the utility model second clamping plate and third clamping plate.
Specific embodiment
As shown in Figure 1, 2, the utility model embodiment is a kind of combination transformer, including epoxy resin poured body 10, electricity
Crimping coil assembly 20, current coil component 30, the support group being arranged between potential winding component 20 and current coil component 30
Part 40, the potential winding component 20 include two voltage iron cores 21, two electricity being separately positioned on each voltage iron core 21
Crimping circle 22, the current coil component 30 include two current ferric cores, two electricity being separately positioned on each current ferric core
Streamline circle 31, the support component 40 include the first clamping plate 41 being arranged on the lower end surface of two voltage iron cores 21, setting
Second clamping plate 42 on the upper surface of two voltage iron cores 21, the third clamping plate 43 positioned at the surface of second clamping plate 42, institute
Multiple support rods 44, corresponding two electricity on the third clamping plate 43 are connected between the second clamping plate 42 stated and third clamping plate 43
It is respectively arranged with a supporting element 45 at streamline circle 31, conflict is respectively arranged on each supporting element 45 in 31 periphery wall of current coil
On arc clamping part 451.The first clamping plate 41, second clamping plate 42 are consolidated by adhesive tape 46 and two voltage iron cores 21 respectively
Fixed connection.First clamping plate, second clamping plate are fixed on two voltage iron cores by adhesive tape, consequently facilitating first clamping plate, the second folder
The assembling of plate and two voltage iron cores.
The combination transformer has the advantages that structure is simple, stable and reliable for performance, good insulation preformance, the combination transformer
Support component uses double layer support structure, and current coil pouring position can be fixed, be ensure that by second clamping plate, third clamping plate
Insulation spacing between current coil and potential winding, and in casting epoxy resin, poured with epoxy resin material can completely into
Enter to inside current coil, potential winding, to ensure that the thickness of the epoxy resin layer of casting is uniform, avoids epoxy resin
It cracks caused by layer uneven thickness, to improve the yield rate of the manufacture of the combination transformer, also improves epoxy resin and pour
The dielectric strength of injection body makes entire combination transformer so that the partial discharge quantity of the combination transformer can be up to state standards
Service life greatly prolong.
