The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will realize that various changes and modifications can be made to various embodiments described herein without departing from the scope and spirit of the present utility model.

[0033] In the description of the utility model, the orientation description, such as the orientation or positional relation of the indication of up, down, front, back, left, right etc. for the orientation or positional relation shown in the drawing, is only for the convenience of describing the utility model and simplifying the description, and is not to indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore can not be understood as limiting the utility model.

[0034] It should be understood that when an element (e.g., a first element) is "connected" with another element (e.g., a second element), the element can be directly connected with the other element, or there can be intervening elements (e.g., a third element) between the element and the other element.

[0035] The utility model discloses an electric meter structure of quick dismounting mutual inductor provides a kind of, as shown in figure Figures 1-13 It includes:

[0036] Electric meter body 10, electric meter body 10 includes mutual inductor module 200, mutual inductor module 200 includes mounting seat 300 and mutual inductor module 210, mounting seat 300 has the threading seat 310 for power line to pass through, and mutual inductor module 210 is detachably connected with threading seat 310.

[0037] Electric meter body 10 contains mutual inductor module 200, and mutual inductor module 200 is responsible for the measurement of electric energy.Mutual inductor module 200 is composed of mounting seat 300 and mutual inductor module 210 two parts.Mounting seat 300 is the component of fixed mutual inductor module 210, it is designed with threading seat 310, for power line to pass through.Mutual inductor module 210 is the component of actual measurement current and voltage, it is fixed with mounting seat 300 by detachable connection mode.Mutual inductor module 210 and the connection mode between threading seat 310 are detachable, which means that when mutual inductor module 210 needs to be maintained or replaced, it can be quickly and conveniently detached from mounting seat 300 without complicated operation to the whole electric meter body 10.The electric meter structure of the utility model improves the maintenance efficiency of electric meter and the replacement speed of mutual inductor 230.In the traditional electric meter structure, the replacement of mutual inductor 230 needs the complicated operation of professional personnel, and this design simplifies this process, reduces maintenance cost and time.Through such structure design, the quick dismounting of mutual inductor 230 in electric meter structure can be realized, and various operation requirements in actual use are facilitated, the practicability and maintenance convenience of electric meter as a whole are improved.

[0038] In some embodiments, the detachable connection of mutual inductor module 210 and threading seat 310 includes but is not limited to the following ways:

[0039] Snap connection mode: corresponding snap structures are arranged on the transformer module 210, and corresponding snap grooves are arranged on the wire seat 310. During installation, the snaps of the transformer module 210 are aligned with the snap grooves of the wire seat 310 and are pressed, so that the snaps are firmly snapped into the snap grooves, thereby realizing the close connection of the two and ensuring that the transformer module 210 can normally collect electric signals and the like. When disassembly is required, the snaps are separated from the snap grooves by pressing a specific unlocking part on the snaps, so that the transformer module 210 can be easily removed.

[0040] Plug-in connection mode: one end of the transformer module 210 is designed into a plug structure, and a socket structure matched with the plug structure is arranged on the wire seat 310. During installation, the plug of the transformer module 210 is aligned with the socket of the wire seat 310 and is directly inserted, and the connection of the two is realized and the normal transmission of electric signals is ensured by means of appropriate friction between the plug and the socket and internal conductive contact structures and the like. During disassembly, the transformer module 210 can be easily pulled out by holding the transformer module 210.

[0041] Bolt connection mode: bolt holes are reserved on corresponding positions of the transformer module 210 and the wire seat 310, and the transformer module 210 and the wire seat 310 are connected and fixed by means of tightening bolts by using appropriate bolts, nut assemblies. During disassembly, the transformer module 210 and the wire seat 310 can be separated by only unscrewing the bolts.

[0042] The working principle of the utility model is as follows:

[0043] The transformer module 210 is integrated in the transformer module 200 of the electric meter body 10, and the transformer module 210 is used for accurately measuring the current or voltage flowing through the electric meter. The module is connected with the power supply line through the wire seat 310, the power supply line passes through the wire seat 310, and the transformer module 210 measures the current or voltage in an inductive manner.

[0044] The connection between the transformer module 210 and the wire seat 310 is designed to be detachable, so that when the transformer module 210 fails or needs to be maintained, the staff can quickly disassemble it from the electric meter body 10 and install a new module, significantly reducing the power-off time and enhancing the reliability of the electric meter. The design of quick disassembly and assembly reduces the time and labor cost required for maintenance, and improves the safety of the electric meter. In different use scenarios, if different specifications of transformers 230 need to be replaced, or the transformers 230 need to be calibrated, this design allows the staff to quickly perform the necessary operations, ensuring that the electric meter can continue to operate normally and will not be interrupted for a long time due to problems of the transformers 230. After maintenance or replacement is completed, the transformer module 210 can be conveniently reinstalled on the electric meter, ensuring the continuity and reliability of the use of the electric meter.

[0045] For example, Figures 8-11The four steps of disassembling and replacing the transformer 230 are shown. When the transformer module 210 at the black wire needs to be replaced, first remove the black wire, then disassemble the transformer module 210, and then replace the new transformer module 210.

[0046] In some embodiments, the transformer module 210 includes a transformer seat 220 and a transformer 230, and the transformer seat 220 is sleeved on the transformer 230.

[0047] The transformer seat 220 is part of the transformer module 210, designed to fix and protect the transformer 230. It is usually made of insulating material to ensure electrical safety. The shape and size of the transformer seat 220 match the transformer 230 to ensure that the transformer 230 can be stably sleeved on the transformer seat 220. The transformer seat 220 is sleeved on the transformer 230, which means that the transformer seat 220 is designed with an inner diameter or cavity that can accommodate the outside of the transformer 230. The sleeving structure helps to fix the transformer 230 and ensures its stability during measurement. The sleeving structure between the transformer seat 220 and the transformer 230 can adopt a quick disassembly and assembly mechanism such as threads, buckles, and spiral compression, to facilitate quick replacement of the transformer 230 when needed. This design allows quick replacement of the transformer 230 without disassembling the entire meter, improving the convenience and efficiency of maintenance.

[0048] Further, the transformer seat 220 includes a base 240 and a plurality of clamping jaws 250 connected to the base 240, and the mounting seat 300 is provided with a clamping groove 320, and the clamping jaw 250 can be sleeved on the transformer 230 and inserted into the clamping groove 320 for clamping.

[0049] The transformer seat 220 is composed of a base 240 and a plurality of clamping jaws 250. The clamping jaws 250 are parts extending from the base 240, which are used to fix the transformer 230 and cooperate with the clamping groove 320 of the mounting seat 300 during installation. The clamping jaw 250 is designed to be sleeved on the transformer 230, which means that the inner diameter or shape of the clamping jaw 250 needs to match the external size of the transformer 230 to ensure that the transformer 230 can be stably fixed in the clamping jaw 250. The mounting seat 300 is provided with a clamping groove 320, which is a recess or hole for fixing the clamping jaw 250 to achieve the fixation between the transformer seat 220 and the mounting seat 300. The design of the clamping groove 320 needs to consider the shape and size of the clamping jaw 250 to ensure that the clamping jaw 250 can be smoothly inserted and firmly clamped. When maintenance or replacement of the transformer 230 is needed, only the clamping mechanism needs to be disengaged, and the transformer seat 220 is removed, and then the necessary maintenance or replacement of the transformer 230 is performed.

[0050] Further, the clamping jaw 250 is provided with a clamping protrusion 260, and the clamping groove 320 includes a wide-mouthed groove 330 and a narrow-mouthed groove 340 connected to the wide-mouthed groove 330. When the clamping protrusion 260 passes through the wide-mouthed groove 330 and the clamping jaw 250 is rotated to be located in the narrow-mouthed groove 340, the narrow-mouthed groove 340 can prevent the clamping jaw 250 from being separated outward from the clamping groove 320.

[0051] The clamping jaw 250 is provided with a clamping protrusion 260, which is a protruding part for interfacing with the clamping groove 320 of the mounting seat 300. The clamping groove 320 includes a wide-mouthed groove 330 and a narrow-mouthed groove 340 connected to the wide-mouthed groove 330. The wide-mouthed groove 330 is matched in shape and size with the clamping protrusion 260 to ensure that the clamping protrusion 260 can pass through smoothly. When installing the transformer seat 220, the clamping protrusion 260 on the clamping jaw 250 first passes through the wide-mouthed groove 330. Then, the clamping protrusion 260 is rotated relative to the clamping groove 320. Since the narrow-mouthed groove 340 is smaller in size than the clamping protrusion 260, the narrow-mouthed groove 340 functions as a limiting part. The design of the narrow-mouthed groove 340 can prevent the clamping jaw 250 from being separated out when subjected to external force, ensuring the reliability of the connection.

[0052] In some embodiments, the clamping jaw 250 is provided with a limiting block 270, and the limiting block 270 and the base 240 define a transformer fitting space 280, in which the transformer 230 is installed.

[0053] The limiting block 270 and the base 240 together define a fitting space of the transformer 230. The main function of the limiting block 270 is to ensure that the transformer 230 can be positioned correctly when installed, preventing the transformer 230 from moving or rotating in the clamping jaw 250, thereby ensuring the stability of the transformer 230 and the accuracy of the measurement. The limiting block 270 can be a protrusion on the clamping jaw 250 or any other structure that can limit the position of the transformer 230. The design of the limiting block 270 needs to be accurately matched with the size and shape of the transformer 230 to ensure that the transformer 230 can be correctly fixed in place. When installing the transformer 230, the transformer 230 will be guided into the clamping jaw 250 and fixed in the correct position by the limiting block 270. When disassembling the transformer 230, the fixing of the limiting block 270 to the transformer 230 needs to be released to take out the transformer 230 from the clamping jaw 250. The design of the limiting block 270 improves the stability of the transformer 230 in the clamping jaw 250, reducing the measurement error caused by improper positioning of the transformer 230. At the same time, the limiting block 270 also improves the structural safety of the transformer seat 220, preventing the transformer 230 from falling out or moving when subjected to external force.

[0054] In some embodiments, the base 240 is provided with an adjusting protrusion 290 for adjusting the position of the base 240.

[0055] The adjusting protrusions 290 allow the position of the base 240 to be adjusted as needed. The adjusting protrusions 290 can be one or more protruding structures on the base 240. By rotating or moving the adjusting protrusions 290, the position of the base 240 can be changed to accommodate different installation conditions or to ensure proper installation of the transformer 230.

[0056] In some embodiments, the electric meter body 10 further comprises a data processing function module 100, which is detachably connected with the transformer module 200.

[0057] The data processing function module 100 is responsible for the collection, processing, and output of electric energy data. By designing the data processing function module 100 and the transformer module 200 to be detachably connected, the electric meter can be modularized, which allows individual parts to be replaced or upgraded independently without the need to replace the entire electric meter. If the data processing function module 100 or the transformer module 200 fails, it can be individually detached and replaced without affecting other parts of the electric meter. This design simplifies the maintenance process, reduces maintenance costs and downtime. As technology advances, it may be necessary to upgrade the data processing capabilities of the electric meter or the performance of the transformer 230. Detachable connection allows users to easily replace old modules with new, more advanced modules.

[0058] Further, the mounting seat 300 is provided with an electrical connection seat 350 connected with the transformer module 210 and a physical connection seat 360. The data processing function module 100 comprises a shell 110 and a data processing module. The shell 110 is connected with the physical connection seat 360, and the data processing module is electrically connected with the electrical connection seat 350.

[0059] The electrical connection seat 350 is a component for electrical connection with the transformer module 210, which is responsible for transmitting the current signal measured by the transformer module 210 to the data processing function module 100. The physical connection seat 360 is responsible for the mechanical connection between the transformer module 210 and the electric meter body 10, ensuring that the transformer module 210 is securely installed on the electric meter body 10.

[0060] The data processing function module 100 comprises a shell 110 and a data processing module. The shell 110 provides physical protection, while the data processing module is responsible for processing the current signal from the transformer module 210.

[0061] The housing 110 is connected to the physical connection seat 360, which usually means that the housing 110 is designed with a specific interface or structure that can match and be fixed with the physical connection seat 360. This connection can be threaded, buckled, bolted or other mechanical connection methods to ensure a stable connection between the data processing function module 100 and the mutual inductor module 200. The data processing module and the electrical connection seat 350 are connected by electrical connection to realize signal transmission. This connection can be plug-in or use a dedicated electrical connector.

[0062] In some embodiments, the physical connection seat includes a connecting column 361 and a positioning member 362, and the housing 110 includes a connection seat 120 matched with the connecting column 361 and a positioning groove 130 matched with the positioning member 362.

[0063] The physical connection seat includes a connecting column 361 and a positioning member 362. The connecting column 361 is used to match the connection seat 120 of the housing, while the positioning member 362 matches the positioning groove 130 of the housing to ensure the correct position and alignment of the mutual inductor module during installation. The connection seat 120 can be an internal structure matched with the connecting column 361, which can be fitted on the connecting column 361 and fixed by fasteners. The positioning member 362 is used to match the positioning groove 130 of the housing to ensure the correct position and alignment of the mutual inductor module during installation. The positioning member 362 can be a protrusion, a groove or other form of positioning structure to ensure that the mutual inductor module does not shift during installation. The positioning groove 130 is a structure on the housing that matches the positioning member 362 to ensure the correct position and alignment of the mutual inductor module during installation. The positioning groove 130 can be a groove, hole or protrusion on the housing to match the shape and size of the positioning member 362. During installation of the mutual inductor module, the connecting column 361 is inserted into the connection seat 120, while the positioning member 362 is inserted into the positioning groove 130 to ensure that the mutual inductor module is correctly installed and fixed in place.

[0064] In some embodiments, the electrical connection seat 350 includes a pin seat connected to the mutual inductor 230, and the data processing module is electrically connected to the pin seat.

[0065] The electrical connection seat 350 is a component for realizing the electrical connection between the mutual inductor 230 and the data processing module. The pin seat is part of the electrical connection seat 350, which provides an interface for the current signal output by the mutual inductor 230 to be connected to the pin seat through the pin or lead, thereby realizing the electrical connection with the data processing module. The data processing module is electrically connected to the pin seat through the electrical connection seat 350 to receive the current signal from the mutual inductor 230. This connection can be direct terminal plug-in or use a dedicated electrical connector. The data processing module is responsible for processing these signals and using the processed data for display, recording or transmission.

[0066] In some embodiments, the wire seat 310 has six.

[0067] Because the existing electric meter and the transformer 230 are installed separately, the electric wire layout in the electric cabinet must adapt to the position of the transformer 230, which often leads to the electric wire crossing, stacking, and even entangling together, so that only three transformers 230 can be generally set. The utility model adopts the structure of the electric meter and the transformer 230 integrated installation and the detachable connection of the transformer module 210 and the threading seat 310, and the design saves the space of the electric cabinet, so that the installation structure of the utility model can install six threading seats 310, and each threading seat 310 corresponds to a transformer module 210. The design of the six threading seats 310 means that the electric meter can be connected with six power supply lines at the same time, and the multi-wire connection can provide more measurement channels, allowing the electric meter to measure the current of multiple circuits at the same time, which is necessary for complex power system monitoring and metering.

[0068] In some embodiments, the mounting seat 300 is provided with a guide rail groove 370 for guide rail installation and a mounting hole 380 for wall hanging installation.

[0069] The guide rail groove 370 is a structure designed on the mounting seat 300, through which the electric meter can be installed on the guide rail to realize quick installation and disassembly, and facilitate maintenance and upgrading. The mounting hole 380 is a reserved hole position on the mounting seat 300, which is used to fix the electric meter on the wall surface or other plane through bolts, screws or other fasteners. Wall hanging installation is suitable for occasions with limited space or fixed position, such as inside the distribution box or on the wall. By providing the guide rail groove 370 and the mounting hole 380, the electric meter can adapt to different installation environments, whether it is an industrial environment, a commercial building or a residential purpose. This design makes the electric meter more versatile and can meet the needs of different customers.
