Abstract
The utility model discloses an anti -electricity -theft for measurement current transformer get electrolytic copper and arrange structure, including the mutual -inductor pouring body, be equipped with on the mutual -inductor pouring body and connect the copper bar and get electric nut and thief -proof screw with the accessory, connect the copper bar and pour into a mould as an organic wholely with the mutual -inductor pouring body, the internal transformer secondary vase that is equipped with of exchangeable pouring is equipped with transformer secondary conducting rod on the transformer secondary vase, get electric nut and pass through threaded connection with transformer secondary conducting rod, it seals the screw and is connected copper bar fixed connection through inlaying to get electric nut. The utility model discloses simple structure, reasonable in design increases the area of contact that gets electric nut and transformer secondary screw rod, avoids two to get the electrolytic copper board and warp, contacts closelyr, connects more reliably. Changed the structure and the connected mode of getting the electrolytic copper, stopped to connect the insecure decompression that causes because of getting the electricity, generated heat, accident such as scaling loss, a screw is inlayed in the installation that has increased the mutual -inductor pouring, has stopped the change mutual -inductor and stealing of causing.
Description
Technical field
The utility model relates to low-voltage electric energy metering technical field, specifically a kind of electricity stealing preventive metering Current Transformer power taking structure of copper bar.
Background technology
Its power taking copper coin of existing Anti-fraudulent use of electricity current transformer, its shortcoming is as follows: 1, power taking copper coin endoporus is round, and diameter of bore is greater than transformer secondary conducting rod 1-2 millimeter, and when being enclosed within Circuit Fault on Secondary Transformer, interior interporal lacuna is larger; 2, copper plate thickness is generally 1-1.5 millimeter, and during installation, nut is directly pressed on copper coin, easily causes copper plate distortion, causes loose contact easily to cause heating, decompression, burning damage accident; 3, existing anti-electricity-theft Current Mutual Inductance power taking copper coin is unfavorable for antitheft, easily takes off instrument transformer.Change mutual inductor ratio stealing.
Utility model content
The purpose of this utility model is to provide a kind of electricity stealing preventive metering Current Transformer power taking structure of copper bar, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of electricity stealing preventive metering Current Transformer power taking structure of copper bar, comprises instrument transformer pour mass; Described instrument transformer pour mass is provided with connection copper bar, and connection copper bar and instrument transformer pour mass are cast for one; Be provided with transformer secondary porcelain vase in mutual inductance pour mass, transformer secondary porcelain vase is provided with transformer secondary conducting rod, and power taking nut and transformer secondary conducting rod are threaded connection; Power taking nut by embedding envelope screw be connected copper bar and be fixedly connected with.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, increase the contact area of power taking copper coin and transformer secondary screw rod; By original nut compression joint type, change power taking nut inner cased type into, avoid two power taking copper plate distortions, make it contact more tight, connect more reliable.Have changed structure and the connected mode of power taking copper, stopped because power taking connects the insecure decompression caused, the accidents such as heating, scaling loss; Add power taking nut is connected copper installation embedding envelope screw with plate, stopped to change instrument transformer and the stealing that causes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cutaway view of the present utility model.
Fig. 3 is the structural representation of transformer secondary porcelain vase in the utility model.
In figure: 1-instrument transformer pour mass, 2-connects copper bar, the embedding envelope screw of 3-, 4-transformer secondary porcelain vase, 5-power taking nut, 6-transformer secondary conducting rod.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, a kind of electricity stealing preventive metering Current Transformer power taking structure of copper bar, comprises instrument transformer pour mass 1; Described instrument transformer pour mass 1 is provided with and connects copper bar 2, connects copper bar 2 and is cast for one with instrument transformer pour mass 1; Be provided with transformer secondary porcelain vase 4 in mutual inductance pour mass 1, transformer secondary porcelain vase 4 is provided with transformer secondary conducting rod 6, and power taking nut 5 is connected with transformer secondary conducting rod 6 by screw thread; Power taking nut 5 by embedding envelope screw 3 be connected copper bar 2 and be fixedly connected with.
The utility model improves Anti-fraudulent use of electricity current transformer power taking structure of copper bar, by single power taking copper bar, changes to power taking nut 5 and is connected copper bar 2 liang of parts; During cast, connection copper bar 2 and instrument transformer pour mass 1 are cast for one, power taking nut 5 is accessory.First power taking nut 5 is tightened against in correct position on transformer secondary conducting rod 6 during in-site installation, then by instrument transformer pour mass 1 gland above.By using embedding envelope screw 3 that power taking nut 5 is fastening with the connection copper bar 2 above instrument transformer pour mass 1, seal wire is finally used to be connected by embedding envelope screw hole.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
