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, Convenient, the easy to use Anti-electricity-theft combined transformer of wiring.
To achieve the above object, the utility model use a kind of Anti-electricity-theft combined transformer, including epoxy resin poured body, Potential winding component, current coil component, the support component being arranged between potential winding component and current coil component, it is described Potential winding component include two voltage iron cores, two potential windings being separately positioned on each voltage iron core, the electricity Streamline coil assembly includes two current ferric cores, two current coils being separately positioned on each current ferric core, the pressure-wire Coil assembly, current coil component, support component are integral by poured with epoxy resin and constitute the epoxy resin poured body, The bottom of the epoxy resin poured body is provided with connecting groove, and multiple copper inserts are provided in the connecting groove, described Current coil, potential winding pass through BVR flexible cord respectively and are electrically connected with each copper insert, and each copper insert is connected to the one of cable On end, and connecting groove is filled with epoxy resin sealant, and the other end of cable is provided with the electricity being exposed at outside epoxy resin sealant Cable joint.
The beneficial effect of above structure is: the bottom of epoxy resin poured body is arranged in connecting groove by the combination transformer, The copper insert for wiring is provided in connecting groove, copper insert is sealed by epoxy resin sealant and drawn by cable, can Effectively prevent stealing, be provided with cable connector on cable, be convenient for terminal block, thus the combination transformer have structure it is simple, Advantage stable and reliable for performance, wiring is convenient, easy to use.
Particularly, the support component includes the first clamping plate being arranged on the lower end surface of two voltage iron cores, setting Second clamping plate on the upper surface of two voltage iron cores, the third clamping plate positioned at the surface of second clamping plate, described second There are two support adjusting screw rod, corresponding two current coils punishment on the third clamping plate for connection between clamping plate and third clamping plate It is not provided with a supporting element, the arc clamping part contradicted on current coil periphery wall is respectively arranged on each supporting element.It should The support component of combination transformer uses double layer support structure, and current coil can be poured position by second clamping plate, third clamping plate Fixation is set, ensure that the insulation spacing between current coil and potential winding, and two adjustable electricity of support adjusting screw rod Streamline circle and potential winding spacing, in casting epoxy resin, poured with epoxy resin material can be completely into arriving current coil, electricity Pressure coil inside avoids epoxy resin layer thickness unevenness and causes to ensure that the thickness of the epoxy resin layer of casting is uniform Cracking also improve the dielectric strength of epoxy resin poured body to improve the yield rate of the manufacture of the combination transformer, To which the partial discharge quantity of the combination transformer can be up to state standards, prolong the service life of entire combination transformer significantly It is long.
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 kind of an Anti-electricity-theft combined transformer, including epoxy resin poured body 10, potential winding component 20, current coil component 30, the branch being arranged between potential winding component 20 and current coil component 30 Support component 40, the potential winding component 20 include two voltage iron cores 21, two be separately positioned on each voltage iron core 21 A potential winding 22, the current coil component 30 include two current ferric cores, two be separately positioned on each current ferric core A current coil 31, the potential winding component 20, current coil component 30, support component 40 by poured with epoxy resin at Epoxy resin poured body 10 described in one and composition, the bottom of the epoxy resin poured body 10 are provided with connecting groove 11, Multiple copper inserts 12 are provided in the connecting groove 11, the current coil 31, potential winding 22 pass through BVR flexible cord respectively 13 are electrically connected with each copper insert 12, and each copper insert 12 is connected on one end of cable 14, and connecting groove 11 is filled with ring Oxygen sealing layer of resin 15, the other end of cable 14 are provided with the cable connector 16 being exposed at outside epoxy resin sealant 15.Described Support component 40 includes the first clamping plate 41 being arranged on the lower end surface of two voltage iron cores 21, is arranged in two voltage iron cores 21 Upper surface on second clamping plate 42, the third clamping plate 43 positioned at the surface of second clamping plate 42, the second clamping plate 42 with Connection is there are two adjusting screw rod 44 is supported between third clamping plate, and corresponding two current coils 31 are punished on the third clamping plate 43 It is not provided with a supporting element 45, the arc clamping contradicted on 31 periphery wall of current coil is respectively arranged on each supporting element 45 Portion 451.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 two support adjusting screw rods can To adjust current coil and potential winding spacing, in casting epoxy resin, poured with epoxy resin material can be electric completely into arriving Inside streamline circle, potential winding, to ensure that the thickness of the epoxy resin layer of casting is uniform, epoxy resin layer thickness are avoided It cracks caused by unevenness, to improve the yield rate of the manufacture of the combination transformer, also improves epoxy resin poured body Dielectric strength makes the use of entire combination transformer so that the partial discharge quantity of the combination transformer can be up to state standards Service life greatly prolongs.
