Technical Field

[0002] As modern society becomes increasingly dependent on electricity supply, the stable operation and efficient maintenance of the power system have become crucial. Especially in the context of accelerated urbanization and continued growth in electricity demand, the replacement and maintenance of electricity meters have become increasingly frequent and complex.

[0003] Meter replacement usually needs to be done during a power outage, which not only brings a lot of inconvenience to users, such as affecting normal production and daily electricity consumption, but also may cause economic losses, such as a drop in business revenue due to power outages. At the same time, power outages also have an impact on the operations of power grid companies, such as reducing power supply reliability and increasing operation and maintenance costs.

[0004] In addition, with the continuous advancement of power technology and the improvement of intelligence level, the requirements for meter replacement and maintenance operations are becoming higher and higher. The traditional power outage operation method can no longer meet the needs of modern power systems, and a more efficient, safe and reliable operation method needs to be developed. Utility Model Content

[0005] The technical problem to be solved and the technical task proposed by the utility model are to improve and perfect the existing technical solutions, and provide a lossless and inductive non-stop power wiring device to achieve safe and efficient meter replacement without power outages, so as to improve the stability and reliability of the power system, reduce operation and maintenance costs, and improve service quality and user experience. To this end, the utility model adopts the following technical solutions.

[0006] A lossless, inductive and non-stop power wiring device comprises a terminal block, a conductive plate arranged in the terminal block, a first conductive rod, a second conductive rod and a third conductive rod arranged below the conductive plate, and a conductive column used for correspondingly electrically connecting the conductive plate with the first, second and third conductive rods. One side of the terminal block is provided with a plurality of line inlets, and the other side of the terminal block is provided with a first line outlet and a second line outlet of the same number as the line inlets. Each conductive plate, the first conductive rod, the second conductive rod and the third conductive rod form a group of wiring units; the first conductive rod, the second conductive rod and the third conductive rod are provided with horizontal wire insertion holes opposite to the corresponding line inlets or wire outlets; the conductive columns are arranged vertically, and the conductive columns of the same group of wiring units correspondingly enter the conductive column connection holes of the first, second and / or third conductive rods from the top of the same conductive plate downward to fasten the wires inserted into the wire insertion holes.

[0007] When it is necessary to replace the meter, insert the lead of the new meter into the corresponding outlet and fasten it through the conductive column. The lead of the new meter is electrically connected to the conductive plate through the corresponding conductive rod, and the conductive plate is electrically connected to the first conductive rod, so as to realize the electrical connection between the new meter and the wire at the inlet. After completing the connection of the new meter, remove the conductive column connected to the conductive rod where the lead of the old meter is located, and pull out the wire of the old meter inserted into the plug hole. Remove the old meter and fix the new meter in the preset position. Changing the meter is simple and quick, without complicated operating steps. The connection method between the conductive column and the conductive rod and the conductive plate is stable and reliable, which effectively prevents safety hazards such as poor contact or short circuit. In this technical solution, the conductive column can be a copper screw.

[0008] The technical solution allows the replacement of electric meters without power outages, thereby greatly improving work efficiency and reducing various losses caused by power outages. For users, no power outages means that their daily life and work will not be disturbed. For power grid companies or electricity users, economic losses and social impacts caused by power outages are avoided.

[0009] This technical solution makes the replacement process of the electric meter simple and quick. At the same time, the connection method between the conductive column and the conductive rod and the conductive plate ensures the stability and safety of current transmission, effectively preventing safety accidents caused by poor contact or short circuit.

[0010] The use of this device can avoid the installation of additional equipment such as disconnectors or circuit breakers before the meter, thus saving related investment costs. In addition, it can also reduce the consumption of auxiliary materials such as insulating tapes and insulating sleeves, reducing maintenance costs. At the same time, since the work of power outage notification is reduced, the manpower and material costs of the power grid company are also saved.

[0011] Since the meter can be replaced without power outage, users can enjoy more timely and better services, which improves user satisfaction. This also establishes a good service image for power grid companies or power users and enhances their market competitiveness.

[0012] As a preferred technical means: the first conductive rod, the second conductive rod and the third conductive rod are plastic-sealed in the terminal seat as inserts.

[0013] This technical solution uses the method of insert molding to tightly combine the conductive rod and the terminal seat to form a stable overall structure; it not only enhances the overall mechanical strength, but also improves the ability to resist impact and vibration, making the entire device more durable and able to operate stably in various harsh environments. The contact between the conductive rod and the terminal seat with insert molding is tighter, reducing the possibility of poor contact, thereby ensuring the stability of electrical performance, reducing the failure rate caused by poor contact, and improving the reliability of the entire system. By insert molding the conductive rod in the terminal seat, the operator is effectively prevented from directly contacting the conductive part, reducing the risk of electric shock. The molding material also has certain insulation properties, further enhancing the safety performance. The design of insert molding makes the structure of the entire device more compact and the installation process simpler and faster. Due to the stable structure and stable electrical performance, the maintenance frequency is relatively low, reducing maintenance costs.

[0014] As a preferred technical means: the first conductive rod, the second conductive rod, and the third conductive rod are insulated from each other, and the three are electrically connected to the conductive plate of the same group of wiring units through a conductive column to realize the electrical connection between the first conductive rod and the second conductive rod and / or the third conductive rod. Since the first conductive rod, the second conductive rod, and the third conductive rod are insulated from each other, it is beneficial to improve safety, effectively prevent the occurrence of electrical failures, and ensure the safety of operators. Through the electrical connection between the conductive column and the conductive plate, the electrical connection between the first conductive rod and the second conductive rod and / or the third conductive rod can be easily realized. This design makes the wiring unit more flexible and changeable in function, and different electrical connection configurations can be made according to actual needs to meet different application scenarios. The design of this technical solution takes into account the stability and reliability of the electrical connection. The close connection between the conductive column and the conductive plate ensures the smooth and stable transmission of current and reduces electrical failures caused by poor contact. At the same time, the insulation design also enhances the durability of the entire wiring unit, enabling it to maintain stable performance during long-term operation.

[0015] As a preferred technical means: the lossless, inductive, and non-stop power wiring device is a lossless, inductive, and non-stop power wiring device for connecting single-phase electric meters; it includes four inlets and eight outlets; the eight outlets are arranged side by side, and the first outlet and the second outlet are arranged alternately. The eight outlets are arranged side by side, with a compact structure, convenient and intuitive wiring, and the operator can see the position and status of all outlets at a glance, without having to search or adjust back and forth between multiple positions, which simplifies the wiring process, improves wiring efficiency, reduces wiring errors and confusion, and improves wiring accuracy and reliability.

[0016] As a preferred technical means: the second conductive rod is the same as the third conductive rod, the sum of the widths of the second conductive rod and the third conductive rod is less than the width of the conductive plate, and the sum of the lengths of the first conductive rod and the second conductive rod or the third conductive rod is less than the length of the conductive plate; the first conductive rod is arranged below one side of the conductive plate, and the second conductive rod and the third conductive rod are arranged side by side below the other side of the conductive plate; the first conductive rod and the second and third conductive rods are staggered in the vertical direction of the terminal seat, and the first, second and third conductive rods are each provided with two vertical conductive column connection holes

[0017] The second conductive rod is identical to the third conductive rod and is arranged side by side, making the internal structure of the entire terminal block more regular and convenient for manufacturing and installation; at the same time, their width is less than the width of the conductive plate, which is convenient for setting side-by-side conductive columns on the conductive plate, and connecting with the second conductive rod and the third conductive rod through the conductive columns, thereby improving space utilization. In addition, the first conductive rod and the second and third conductive rods are staggered in the upper and lower directions of the terminal block. This staggered layout not only avoids interference between the conductive rods, but also avoids the wire inserted into the first conductive rod from being mistakenly electrically connected to the second and third conductive rods as conductors. Each conductive rod is provided with two vertical conductive column connection holes. The two conductive column connection holes improve the stability and reliability of the connection and ensure the smoothness and safety of current transmission.

[0018] As a preferred technical means: the bottom of the terminal seat is provided with a first opening groove and a second opening groove which are open downwards; the first opening groove is located in the middle position of the bottom of the terminal seat, and the first opening groove is located between the first conductive rod and the second and third conductive rods; the second opening groove is located between adjacent wiring units.

[0019] By providing the first opening groove and the second opening groove, the wall thickness of the terminal block can be kept uniform, which helps to maximize the use of materials during the manufacturing process and reduce unnecessary material waste. The uniform wall thickness can also improve the mechanical strength of the terminal block, ensuring that it has sufficient stability when subjected to external pressure and stress. It can make the entire device lighter and adapt to more application scenarios.

[0020] The design of the open groove makes the injection mold manufacturing simpler, reduces the complexity of the mold, and improves the efficiency and success rate of injection molding production. During the injection molding process, the plastic can flow more evenly into every corner of the mold, reducing the generation of bubbles and defects and improving the quality of the product.

[0021] The first opening groove is located between the first conductive rod and the second and third conductive rods, providing a clear reference for the positioning of the conductive rod during the injection molding process. It ensures that the conductive rod is accurately placed at the predetermined position during injection molding to avoid position deviation or tilt, thereby ensuring the connection stability and electrical performance between the conductive rod and the terminal block.

[0022] The second opening slot is located between adjacent wiring units, forming an effective isolation area, reducing the possibility of electrical contact between different wiring units. The insulation performance between adjacent wiring units is enhanced, the risk of short circuit or leakage caused by electrical contact is reduced, and the safety and reliability of the entire terminal block are improved.

[0023] As a preferred technical means: the lossless, inductive, and non-stop power wiring device is a lossless, inductive, and non-stop power wiring device for connecting three-phase electric meters; it includes eight incoming wires and sixteen outgoing wires; the eight incoming wires are arranged side by side, and the sixteen outgoing wires are arranged in two rows, the first outgoing wire and the second outgoing wire are each in one row.

[0024] The eight inlets are arranged side by side. This layout makes it easier to access the wires. The operator can intuitively see the location of each inlet, avoiding a complicated search process. The sixteen outlets are divided into two rows, the first outlet and the second outlet are in one row each. The row design makes the outlets more orderly and easy to manage and maintain. The upper and lower rows effectively reduce the overall length and improve the compactness of the structure. The reasonable layout of the inlets and outlets ensures the convenience of wiring, effectively prevents the wires from being messy and disorderly, and reduces the possibility of wiring errors. It meets the long-term needs of three-phase meter connection.

[0025] As a preferred technical means: the conductive plate, the first conductive rod, the second conductive rod, and the third conductive rod have the same width, the first conductive rod, the second conductive rod, and the third conductive rod are symmetrically arranged in the front-to-back direction, the first conductive rod, the second conductive rod, and the third conductive rod are respectively located at the front, middle, and rear positions directly below the conductive plate, and the first conductive rod and the third conductive rod are located at the same height, and the second conductive rod is lower than the first conductive rod and the third conductive rod; the first, second, and third conductive rods are each provided with two vertical conductive column connection holes.

[0026] By arranging the three conductive bars in an up-down staggered manner at the front, middle and rear positions of the terminal block, the space inside the terminal block can be more effectively utilized, so that the terminal block can accommodate all the conductive bars without increasing its size. The inlet opposite to the first conductive bar plug-in hole faces one side of the terminal block; the outlet opposite to the second and third conductive bar plug-in holes faces the other side of the terminal block; because the second and third conductive bars are staggered up and down, the outlets opposite to the second and third conductive bar plug-in holes can be arranged up and down, which not only makes the structure of the entire terminal block more compact, but also optimizes space utilization; in a limited space, more conductive bars and outlets can be more effectively placed to meet the wiring requirements of the three-phase meter.

[0027] The staggered arrangement of the conductive rods makes the internal structure of the terminal block more stable. Each conductive rod has its own unique position and support point, which can evenly share the external pressure and stress, enhancing the structural stability of the entire terminal block.

[0028] By staggering the conductive bars, electrical interference between them can be reduced; each conductive bar has its own independent path and isolation area, reducing the risk of signal distortion or failure due to electrical interference.

[0029] The symmetrical arrangement of the first, second, and third conductive bars helps to balance the stress distribution inside the terminal block and improve the stability and reliability of the overall structure; the first conductive bar and the third conductive bar are at the same height, and the second conductive bar is lower than the first two. This layout makes full use of the space inside the terminal block. At the same time, since the width of the conductive bar is the same as the width of the conductive plate, the space utilization rate is further improved, so that the terminal block can accommodate more wiring units. Each conductive bar is provided with two vertical conductive column connection holes, which improves the stability and reliability of the wiring.

[0030] As a preferred technical means: a third opening groove and a fourth opening groove opening downward are provided at the bottom of the terminal seat, the third opening groove is located in the terminal seat below the first conductive rod, the fourth opening groove is located in the terminal seat below the third conductive rod, and the third opening groove and / or the fourth opening groove are provided with a cover plate.

[0031] The third opening slot and / or the fourth opening slot is provided with a cover plate, which can prevent dust, debris, etc. from entering the terminal block and affecting normal operation, and can also prevent operators from accidentally touching the conductive part, thereby improving the safety of use. Providing three opening slots and a fourth opening slot can reduce the weight of the terminal block, reduce costs, and also facilitate the positioning of the first conductive rod, the second conductive rod, and the third conductive rod during injection molding.

[0032] As a preferred technical means: the top of the terminal block is provided with a protruding rib, which separates the conductive column holes between adjacent wiring units and the conductive column holes between the first conductive rod and the second conductive rod and the third conductive rod; the four corners of the terminal block are provided with positioning feet, and the positioning feet are clamped with an insulating transparent observation sheet, and the observation sheet covers the top surface of the terminal block. When it is necessary to replace the wiring, remove the observation sheet and then operate the conductive column. The ribs set on the top of the terminal block cleverly separate the conductive column holes between adjacent wiring units and the conductive column holes between the first conductive rod and the second and third conductive rods, which not only enhances the structural strength of the terminal block, but also effectively prevents electrical interference between different wiring units, and improves the stability and safety of the work. The four corners of the terminal block are provided with positioning feet, which can clamp the insulating transparent observation sheet so that the observation sheet can stably cover the top surface of the terminal block. The use of the insulating transparent observation sheet enables the operator to intuitively observe the wiring conditions inside the terminal block, including the connection status of the conductive column, the layout of the wiring unit, etc., which facilitates daily maintenance and inspection work, reduces the difficulty of operation, and improves work efficiency. The observation piece is made of insulating transparent material, which not only has good insulation performance and can effectively prevent electrical accidents, but also the transparent design allows operators to clearly see the wiring situation, further improving the safety of operation. When it is necessary to replace the wiring, simply remove the observation piece to operate the conductive column, which simplifies the steps of replacing the wiring, reduces the difficulty of operation, and improves work efficiency.

[0033] Beneficial effects:

[0034] The technical solution allows the replacement of electric meters without power outages, thereby greatly improving work efficiency and reducing various losses caused by power outages. For users, no power outages means that their daily life and work will not be disturbed. For power grid companies or electricity users, economic losses and social impacts caused by power outages are avoided.

[0035] This technical solution makes the replacement process of the electric meter simple and quick. At the same time, the connection method between the conductive column and the conductive rod and the conductive plate ensures the stability and safety of current transmission, effectively preventing safety accidents caused by poor contact or short circuit.

[0036] The use of this device can avoid the installation of additional equipment such as disconnectors or circuit breakers before the meter, thus saving related investment costs. In addition, it can also reduce the consumption of auxiliary materials such as insulating tapes and insulating sleeves, reducing maintenance costs. At the same time, since the work of power outage notification is reduced, the manpower and material costs of the power grid company are also saved.

One side of the terminal block 1 is provided with a plurality of line inlets 101, and the other side of the terminal block 1 is provided with line outlets twice the number of the line inlets 101. The line outlets include the same number of first line outlets 102 and second line outlets 103. Each line inlet 101 forms a group of connection holes with a first line outlet 102 and a second line outlet 103. The wiring port of the wire unit 10; each group of wiring units 10 includes a conductive plate 5, a first conductive rod 2 arranged below one side of the conductive plate 5, a second conductive rod 3 and a third conductive rod 4 located below the other side of the conductive plate 5; the first conductive rod 2, the second conductive rod 3, and the third conductive rod 4 are provided with a horizontal wire insertion hole 7 opposite to the corresponding wire inlet 101 or wire outlet; the conductive column 6 is vertically arranged, and the conductive columns 6 of the same group of wiring units 10 enter the conductive column connection holes of the first, second and / or third conductive rods 4 from the top of the same conductive plate 5 downward to fasten the wires inserted into the wire insertion holes 7.

[0053] When it is necessary to replace the meter, insert the lead of the new meter into the corresponding outlet and fasten it through the conductive column 6, electrically connect the lead of the new meter to the conductive plate 5 through the corresponding conductive rod, and electrically connect the conductive plate 5 to the first conductive rod 2, so as to realize the electrical connection between the new meter and the wire at the inlet 101; after completing the connection of the new meter, remove the conductive column 6 connected to the conductive rod where the lead of the old meter is located, and pull out the wire of the old meter inserted into the plug hole 7; remove the old meter and fix the new meter in the preset position. The meter replacement work is simple and quick, without complicated operating steps; the connection method of the conductive column 6 with the conductive rod and the conductive plate 5 is stable and reliable, which effectively prevents safety hazards such as poor contact or short circuit. In this technical solution, the conductive column 6 is a copper screw. The first, second and third conductive rods 4 are copper rods. The conductive column connection hole is provided with a thread matching the copper screw.

[0054] The technical solution allows the replacement of electric meters without power outages, thereby greatly improving work efficiency and reducing various losses caused by power outages. For users, no power outages means that their daily life and work will not be disturbed. For power grid companies or electricity users, economic losses and social impacts caused by power outages are avoided.

[0055] This technical solution makes the replacement process of the electric meter simple and quick. At the same time, the connection method of the conductive column 6, the conductive rod and the conductive plate 5 ensures the stability and safety of current transmission, and effectively prevents safety accidents caused by poor contact or short circuit.

[0056] The use of this device can avoid the installation of additional equipment such as disconnectors or circuit breakers before the meter, thus saving related investment costs. In addition, it can also reduce the consumption of auxiliary materials such as insulating tapes and insulating sleeves, reducing maintenance costs. At the same time, since the work of power outage notification is reduced, the manpower and material costs of the power grid company are also saved.

[0057] Since the meter can be replaced without power outage, users can enjoy more timely and better services, which improves user satisfaction. This also establishes a good service image for power grid companies or power users and enhances their market competitiveness.

[0058] The above technical solution is applicable to single-phase electricity meters, three-phase electricity meters, etc.

The corresponding terminal block 1 suitable for the single-phase meter is provided with four wire inlets 101, a first wire outlet 102 and a second wire outlet 103; Figure 1-6 shown.

[0060] In order to improve the strength, this technical solution uses the method of insert molding to tightly combine the conductive rod and the terminal seat 1 to form a stable overall structure; it not only enhances the overall mechanical strength, but also improves the ability to resist impact and vibration, making the entire device more durable and able to operate stably in various harsh environments. The contact between the conductive rod and the terminal seat 1 with insert molding is tighter, reducing the possibility of poor contact, thereby ensuring the stability of electrical performance, reducing the failure rate caused by poor contact, and improving the reliability of the entire system. By insert molding the conductive rod in the terminal seat 1, it effectively prevents the operator from directly contacting the conductive part, reducing the risk of electric shock. The molding material also has certain insulation properties, further enhancing the safety performance. The design of insert molding makes the structure of the entire device more compact and the installation process simpler and faster. Due to the stable structure and stable electrical performance, the maintenance frequency is relatively low, reducing the maintenance cost.

[0061] To improve safety, the first conductive rod 2, the second conductive rod 3, and the third conductive rod 4 are insulated from each other, and the three are electrically connected to the conductive plate 5 of the same group of wiring unit 10 through the conductive column 6 to realize the electrical connection between the first conductive rod 2 and the second conductive rod 3 and / or the third conductive rod 4. Since the first conductive rod 2, the second conductive rod 3 and the third conductive rod 4 are mutually insulated, it is beneficial to improve safety, effectively prevent the occurrence of electrical faults, and ensure the safety of operators. Through the electrical connection between the conductive column 6 and the conductive plate 5, the electrical connection between the first conductive rod 2 and the second conductive rod 3 and / or the third conductive rod 4 can be easily realized. This design makes the wiring unit 10 more flexible and changeable in function, and different electrical connection configurations can be made according to actual needs to meet different application scenarios. The design of this technical solution takes into account the stability and reliability of the electrical connection. The close connection between the conductive column 6 and the conductive plate 5 ensures the smooth and stable transmission of current and reduces electrical faults caused by poor contact. At the same time, the insulation design also enhances the durability of the entire wiring unit 10, enabling it to maintain stable performance during long-term operation.

[0062] For the convenience of wiring, in this embodiment, eight outlets are arranged side by side, and the first outlet 102 and the second outlet 103 are arranged alternately. The eight outlets are arranged side by side, the structure is compact, the wiring is convenient and intuitive, the operator can see the position and status of all outlets at a glance, and there is no need to search or adjust back and forth between multiple positions, which simplifies the wiring process, improves wiring efficiency, reduces wiring errors and confusion, and improves the accuracy and reliability of wiring.

[0063] To facilitate the processing of the terminal block 1 and improve the compactness of the structure, the second conductive rod 3 is the same as the third conductive rod 4, the second and third conductive rods 4 are arranged side by side, the sum of the widths of the second conductive rod 3 and the third conductive rod 4 is less than the width of the conductive plate 5, and the sum of the lengths of the first conductive rod 2 and the second conductive rod 3 or the third conductive rod 4 is less than the length of the conductive plate 5; the first conductive rod 2 and the second and third conductive rods 4 are staggered in the upper and lower directions of the terminal block 1, and the first, second and third conductive rods 4 are each provided with two vertical conductive column connection holes.

[0064] The second conductive rod 3 is identical to the third conductive rod 4 and is arranged side by side, making the internal structure of the entire terminal block more regular and convenient for manufacturing and installation; at the same time, their width is less than the width of the conductive plate 5, which facilitates the arrangement of conductive columns 6 arranged side by side on the conductive plate 5, and connects with the second conductive rod 3 and the third conductive rod 4 through the conductive columns 6, thereby improving space utilization. In addition, the first conductive rod 2 and the second and third conductive rods 4 are staggered in the upper and lower directions of the terminal block 1. This staggered layout not only avoids interference between the conductive rods, but also avoids the wire inserted into the first conductive rod 2 from being mistakenly electrically connected to the second and third conductive rods 4 as conductors. Each conductive rod is provided with two vertical conductive column connection holes, which improve the stability and reliability of the connection and ensure the smoothness and safety of current transmission.

[0065] In order to increase insulation and further reduce the volume of the terminal block 1, a first opening groove 104 and a second opening groove 105 opening downward are opened at the bottom of the terminal block 1; the first opening groove 104 is located in the middle position of the bottom of the terminal block 1, and the first opening groove 104 is located between the first conductive rod 2 and the second and third conductive rods 4; the second opening groove 105 is located between adjacent wiring units 10.

[0066] By providing the first opening groove 104 and the second opening groove 105, the wall thickness of the terminal block 1 can be kept uniform, which helps to maximize the use of materials during the manufacturing process and reduce unnecessary material waste. The uniform wall thickness can also improve the mechanical strength of the terminal block 1, ensuring that it has sufficient stability when subjected to external pressure and stress. It can make the entire device lighter and adapt to more application scenarios.

[0067] The design of the open groove makes the injection mold manufacturing simpler, reduces the complexity of the mold, and improves the efficiency and success rate of injection molding production. During the injection molding process, the plastic can flow more evenly into every corner of the mold, reducing the generation of bubbles and defects and improving the quality of the product.

[0068] The first opening groove 104 is located between the first conductive rod 2 and the second and third conductive rods 4, providing a clear reference for the positioning of the conductive rods during the injection molding process, ensuring that the conductive rods are accurately placed at the predetermined position during injection molding, avoiding positional deviation or tilting, and ensuring the connection stability and electrical performance between the conductive rods and the terminal block 1.

[0069] The second opening groove 105 is located between adjacent wiring units 10, forming an effective isolation area, reducing the possibility of electrical contact between different wiring units 10. The insulation performance between adjacent wiring units 10 is enhanced, the risk of short circuit or leakage caused by electrical contact is reduced, and the safety and reliability of the entire wiring terminal are improved. At the same time, the volume of the terminal block 1 can also be reduced.

[0070] In order to facilitate the inspection of the wiring conditions and ensure safety, the top of the terminal block 1 is provided with a protruding rib 108, which separates the conductive column holes between adjacent wiring units 10 and the conductive column holes between the first conductive rod 2 and the second conductive rod 3 and the third conductive rod 4; the four corners of the terminal block 1 are provided with positioning feet 109, which are clamped with the insulating transparent observation sheet 9, and the observation sheet 9 covers the top surface of the terminal block 1. When the wiring needs to be replaced, the observation sheet 9 is removed and the conductive column 6 is operated. The rib 108 set on the top of the terminal block 1 cleverly separates the conductive column holes between adjacent wiring units 10 and the conductive column holes between the first conductive rod 2 and the second and third conductive rods 4, which not only enhances the structural strength of the terminal block 1, but also effectively prevents electrical interference between different wiring units 10, and improves the stability and safety of the work. The four corners of the terminal block 1 are provided with positioning feet 109, which can clamp the insulating transparent observation sheet 9, so that the observation sheet 9 can stably cover the top surface of the terminal block 1. The use of the insulating transparent observation piece 9 enables the operator to intuitively observe the wiring conditions inside the terminal block 1, including the connection status of the conductive column 6, the layout of the wiring unit 10, etc., which facilitates daily maintenance and inspection work, reduces the difficulty of operation, and improves work efficiency. The observation piece 9 is made of insulating transparent material, which not only has good insulation performance and can effectively prevent the occurrence of electrical accidents, but also the transparent design allows the operator to clearly see the wiring conditions, further improving the safety of operation. When it is necessary to replace the wiring, simply remove the observation piece 9 to operate the conductive column 6, which simplifies the steps of replacing the wiring, reduces the difficulty of operation, and improves work efficiency.

[0071] A lossless and inductive non-stop power wiring device of the present technical solution adopts a three-fold three-way method. From the perspective of the current single-phase meter rotation and the main body structure, it is understood as a false three-fold three-way, which is refined into a false three-fold false three-way. The reason for this is that it does not have a true three-fold, that is, there is one stack of the conductive plate 5, and there are two stacks on the incoming line side and the two outgoing line sides, three independent stacks; a false three-way, all copper screws are screwed together, which is a true three-way. In actual work, the incoming line side is screwed with screws, which is one-way; an empty meter box, that is, no low-voltage single-phase meter is installed, all the screws on the outgoing line side are not installed, so at this time the two outgoing line ends are not connected; when a meter is installed, the state is two-way; when there is a meter rotation, there are short-term three-electricity at the two outgoing line ends, and only two-way exists at the end of the meter rotation. From the current three-phase meter rotation perspective and the main body structure, it is understood as a false three-fold three-way, which is refined into a true three-fold false three-way. The reason for this is that there are three layers on its side, that is, the upper copper plate, the incoming line side and the two outgoing line sides. The fake tee, all the copper screws are screwed together, which is a true tee. In actual work, the incoming line side is screwed with screws, which is one-way. The empty meter box, that is, the low-voltage single-phase meter is not installed, all the screws on the outgoing line side are not installed, so the two outgoing line ends are not connected at this time; when a meter is installed, the state is two-way; when there is a meter rotation, there are short-term three-way electricity at the two outgoing line ends, and only two-way exists at the end of the meter rotation. In the three-layer tee, the copper screws play the role of conducting electricity and pressing the incoming and outgoing lines; the ingoing and outgoing lines use conductive rods to prevent overheating of the contact points.

[0072] There are two types of applications for triple-stack tees. One is an intuitive tee, that is, all screws are fully installed, one input and two outputs, to achieve the function of current distribution on demand; the other is one input, one output, common use and one output standby, that is, two-output wiring, one is common use and the other is standby, but there is a sequence of input and output. After the standby is put into operation, the original common use is output, and after the original common use is output, the standby role is changed to common use in the book, and the original common role that is output is changed to standby. In order to achieve lossless, inductive and non-stop wiring, this embodiment adopts the second application.

[0073] The following is a detailed description of the installation and rotation of meters:

[0078] 3. Power-on inspection: Close the circuit breaker of the meter box, power on, check whether the meter is operating normally, and the new installation of the meter is completed.

[0079] 2.0.4kV low voltage single-phase meter rotation

[0080] 1. Material preparation: Four BV-10 yellow, green, red and black wires coming from the power supply side have been connected to the meter box, terminal block 1, the meter box outlet circuit breaker has been installed, and a new meter is to be installed. At this time, the meter box outlet circuit breaker is in the closed state.

[0081] 4 Installation: There is one screw not installed on the outlet side of terminal block 1.

Take out all the original meters and connecting wires, check whether the newly installed meter is operating normally, plug in the insulation observation piece 9, and the meter rotation work is completed.

[0082] Embodiment 2:

[0083] The same points as the embodiment are not repeated here, the difference is that the embodiment is applicable to a three-phase electricity meter; the corresponding wiring terminals matching the three-phase electricity meter include eight incoming ports 101 and sixteen outgoing ports; the eight incoming ports 101 are arranged side by side, and the sixteen outgoing ports are arranged in two rows, the first outgoing port 102 and the second outgoing port 103 are each in one row.

[0084] According to the actual functional requirements, using this device, the three-phase four-wire meter originally used 8 meter end connecting wires, including 2 neutral wires, but now can use 7 wires, that is, a neutral wire can be selected at the meter end.

[0085] The eight inlets 101 are arranged side by side. This layout makes it more convenient to access the wires. The operator can intuitively see the location of each inlet 101, avoiding a complicated search process. The sixteen outlets are divided into two rows, the first outlet 102 and the second outlet 103 are each in a row. The row design makes the outlets more orderly and easy to manage and maintain. The upper and lower rows effectively reduce the overall length and improve the compactness of the structure. The reasonable layout of the inlets 101 and the outlets ensures the convenience of wiring, effectively prevents the wires from being messy and disorderly, and reduces the possibility of wiring errors. It meets the long-term needs of three-phase meter connection.

[0086] In order to reduce the width of the terminal base 1 , the first conductive bar 2 , the second conductive bar 3 , and the third conductive bar 4 are arranged in an up-down staggered manner at the front, middle, and rear positions of the terminal base 1 .

[0087] By arranging the three conductive bars in an up-down staggered manner at the front, middle and rear positions of the terminal block 1, the space inside the terminal block 1 can be more effectively utilized, so that the terminal block 1 can accommodate all the conductive bars without increasing its size. The inlet 101 opposite to the wire insertion hole 7 of the first conductive bar 2 faces one side of the terminal block 1; the outlet opposite to the wire insertion holes 7 of the second and third conductive bars 4 faces the other side of the terminal block 1; because the second and third conductive bars 4 are staggered up and down, the outlets opposite to the wire insertion holes 7 of the second and third conductive bars 4 can be arranged up and down, which not only makes the structure of the entire terminal block 1 more compact, but also optimizes the space utilization; in a limited space, more conductive bars and outlets can be more effectively placed to meet the wiring requirements of the three-phase meter.

[0088] The staggered arrangement of the conductive rods makes the internal structure of the terminal block 1 more stable. Each conductive rod has its own unique position and support point, which can evenly share the external pressure and stress, thereby enhancing the structural stability of the entire terminal block.

[0089] By staggering the conductive bars, electrical interference between them can be reduced; each conductive bar has its own independent path and isolation area, reducing the risk of signal distortion or failure due to electrical interference.

[0090] In order to improve the compactness of the structure, the width of the first, second and third conductive bars 4 is the same as that of the conductive plate 5, the first conductive bar 2, the second conductive bar 3 and the third conductive bar 4 are symmetrically arranged, the first conductive bar 2 and the third conductive bar 4 are located at the same height, and the second conductive bar 3 is lower than the first conductive bar 2 and the third conductive bar 4; the first, second and third conductive bars 4 are each provided with two vertical conductive column connection holes; a third opening groove 106 and a fourth opening groove 107 opening downward are provided at the bottom of the terminal seat 1, the third opening groove 106 is located in the terminal seat 1 below the first conductive bar 2, the fourth opening groove 107 is located in the terminal seat 1 below the third conductive bar 4, and the third opening groove 106 and / or the fourth opening groove 107 are provided with a cover plate 8.

[0091] The first, second and third conductive rods 4 are symmetrically arranged, which helps to balance the stress distribution inside the terminal block 1 and improve the stability and reliability of the overall structure; the first conductive rod 2 and the third conductive rod 4 are located at the same height, and the second conductive rod 3 is lower than the first two. This layout makes full use of the space inside the terminal block 1. At the same time, since the width of the conductive rod is the same as the width of the conductive plate 5, the space utilization rate is further improved, so that the terminal block 1 can accommodate more wiring units 10. Each conductive rod is provided with two vertical conductive column connection holes, which improves the stability and reliability of the wiring. The third opening slot 106 and / or the fourth opening slot 107 are provided with a cover plate 8, which can prevent dust, debris, etc. from entering the terminal block 1 and affecting normal operation, and can also prevent operators from accidentally touching the conductive part, thereby improving the safety of use.

[0092] In this embodiment, the fourth opening slot 107 is provided with a cover plate 8, and a third opening slot 106 is provided below the first conductive rod 2. The third opening slot 106 is a small-sized opening slot. Two third opening slots 106 are provided below a first conductive rod 2, and the third opening slots 106 can be opposite to the conductive column connection hole.

[0093] The lossless, inductive, and non-stop power wiring device shown above is a specific embodiment of the present utility model, which has embodied the substantial characteristics and progress of the present utility model. According to actual use needs and under the guidance of the present utility model, equivalent modifications in shape, structure, etc. can be made to it, which are all within the protection scope of this scheme.
