Description

Technical Field

[0001] This utility model relates to the field of electricity meter maintenance technology, and in particular to a device for replacing single-phase electricity meters without interrupting power supply. Background Technology

[0002] Currently, the common practice for replacing meters for low-voltage users is to "disconnect the switch first, then replace the meter," which results in a relatively long disconnection time for the user's load, leading to low user acceptance. Power supply reliability plays a crucial role in the business environment evaluation system, and power outages during meter replacement can severely impact the quality of power company services, causing users to be unable to use electricity normally and affecting their perception of electricity usage.

[0003] Chinese invention patent CN104701692A discloses an uninterruptible meter replacement socket, comprising a housing with spaced current terminals arranged on the housing. The front ends of the current terminals extend outside the housing, while the rear ends are located inside the housing. A connection window is provided on the upper part of the housing at the rear of the current terminals, and a cover plate is provided over the connection window. The connector includes a connecting base with at least one pair of conductive pins at its lower part. These two conductive pins are interconnected, and protective feet are provided on the outside of the conductive pins.

[0004] The aforementioned uninterruptible meter replacement sockets have high current conductivity, low heat generation, and low power loss, allowing for meter replacement without interrupting the power supply. However, the internal load continues to operate and consume power during the replacement of meter components, so power consumption during the replacement period should be metered to improve user experience and reduce losses for the power company. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a non-stop meter replacement device for single-phase electricity meters. This non-stop meter replacement device can replace meters without interrupting power supply and can also control the power consumption of the internal load during meter replacement.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A device for uninterrupted power-off meter replacement for single-phase electricity meters includes a single-phase electricity meter, a connector, and a first conductor. A wire is connected to the single-phase electricity meter through the connector. The first conductor can be inserted into the connector to disconnect the power to the single-phase electricity meter. The connector includes a housing, a spring, a connecting piece, a first conductive piece, and a second conductive piece. The connecting piece is fixed inside the housing by the spring. The housing has a corresponding insertion hole for the connecting piece. The connecting piece and the first conductive piece are fixedly connected. The second conductive piece is fixed to the housing. When the spring is not disturbed by external force, the connecting piece and the second conductive piece are connected. When the spring is compressed inward by force, the connecting piece and the second conductive piece are disconnected, and the second conductive piece is electrically connected to the single-phase electricity meter.

[0008] Furthermore, the first conductor includes a first housing, a first conductive pin, and a first power indicator light. The first conductive pin is fixed to the first housing, and the first power indicator light is mounted on the top of the first housing.

[0009] Furthermore, the first conductive pin includes a first pin, a second pin, a third pin, and a fourth pin, wherein the first pin and the second pin are electrically connected, and the third pin and the fourth pin are electrically connected.

[0010] Furthermore, it also includes a second conductor, which can be inserted into the connector to disconnect the power to the single-phase meter while also allowing for the connection of an external independent meter to measure electricity.

[0011] Furthermore, the second conductor includes a second housing, a second conductive pin, and a second power indicator light. The second conductive pin is fixed to the second housing, and the second power indicator light is mounted on the top of the second housing.

[0012] Furthermore, the second conductive pin includes a fifth pin, a sixth pin, a seventh pin, and an eighth pin, all of which are electrically connected to an independent electricity meter.

[0013] Furthermore, both the first conductive pin and the second conductive pin can be inserted into the socket and fixed.

[0014] Furthermore, mounting bases are provided on both the left and right sides of the housing.

[0015] Furthermore, the housing has an opening for the first conductive sheet to move.

[0016] Furthermore, the connector also includes an insulating gasket, and the spring is fixedly connected to the inner wall of the housing and the connecting piece respectively through the insulating gasket.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0025] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0026] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0028] Example 1:

[0029] like Figures 1-5 As shown in the figure, this embodiment provides a non-disconnect meter replacement device for a single-phase electricity meter, which includes a single-phase electricity meter 1, a connector 2, and a first conductor 3. The wire is connected to the single-phase electricity meter 1 through the connector 2. The first conductor 3 can be inserted into the connector 2 to disconnect the power to the single-phase electricity meter 1. The connector 2 includes a housing 21, a spring 22, a connecting piece 23, a first conductive piece 24, and a second conductive piece 25. The connecting piece 23 is fixed inside the housing 21 by the spring 22. The housing 21 has a socket 6 corresponding to the connecting piece 23. The connecting piece 23 and the first conductive piece 24 are fixedly connected. The second conductive piece 25 is fixed to the housing 21. When the spring 22 is not disturbed by external force, the connecting piece 23 and the second conductive piece 25 are connected. When the spring 22 is compressed inward by force, the connecting piece 23 and the second conductive piece 25 are disconnected, and the second conductive piece 25 is electrically connected to the single-phase electricity meter 1. In actual use, the single-phase meter 1 is used to measure the power consumption of the internal load of the line. The single-phase meter 1 is connected to the line through the connector 2 and short-circuited by the first conductor 3 to disconnect the metering of the single-phase meter 1. The housing 21 is used to install the connecting devices. The connecting piece 23 is used to connect the first conductive piece 24 and the second conductive piece 25. The first conductive piece 24 is used to connect the line, and the second conductive piece 25 is used to connect the single-phase meter 1. The spring 22 can drive the connecting piece 23 and the first conductive piece 24 to move, so that the second conductive piece 25 and the single-phase meter 1 are not energized, thereby facilitating the replacement and maintenance of the single-phase meter 1.

[0030] In this embodiment, the first conductor 3 includes a first housing 31, a first conductive pin 32, and a first power indicator light 33. The first conductive pin 32 is fixed to the first housing 31, and the first power indicator light 33 is installed on the top of the first housing 31. In actual use, the first housing 31 is used to install connected devices, the first power indicator light 33 is used to indicate whether the first conductive pin 32 is energized, and the first conductive pin 32 is used to disconnect the single-phase meter 1 from the circuit, so that the single-phase meter 1 is not energized, which facilitates the maintenance and replacement of the single-phase meter 1.

[0031] In this embodiment, the first conductive pin 32 includes a first pin 321, a second pin 322, a third pin 323, and a fourth pin 324. The first pin 321 and the second pin 322 are electrically connected, and the third pin 323 and the fourth pin 324 are electrically connected. In actual use, the first pin 321 and the second pin 322 are short-circuited, and the third pin 323 and the fourth pin 324 are short-circuited, so that the entire circuit can operate normally without the connection of the single-phase meter 1, achieving the effect of uninterrupted power supply during meter replacement.

[0032] In this embodiment, a second conductor 4 is also included. The second conductor 4 can be inserted into the connector 2 to disconnect the power to the single-phase meter 1, while also allowing an external independent meter 5 to be connected to measure the electricity. In actual use, while ensuring that the internal load remains uninterrupted during the replacement of the single-phase meter 1, it is also necessary to measure the electricity consumption of the internal charge during the meter replacement period. Therefore, the second conductor 4 is required to accurately measure the electricity consumption during the short circuit.

[0033] In this embodiment, the second conductor 4 includes a second housing 41, a second conductive pin 42, and a second power indicator light 43. The second conductive pin 42 is fixed to the second housing 41, and the second power indicator light 43 is mounted on the top of the second housing 41. In actual use, the second housing 41 is used to install connected devices, the second power indicator light 43 is used to indicate whether the second conductive pin 42 is energized, and the second conductive pin 42 is used to disconnect the power to the single-phase meter 1 and connect the independent meter 5 to the circuit for metering.

[0034] In this embodiment, the second conductive pin 42 includes a fifth pin 421, a sixth pin 422, a seventh pin 423, and an eighth pin 424, all of which are electrically connected to the independent meter 5. In actual use, one end of each of the fifth pin 421, sixth pin 422, seventh pin 423, and eighth pin 424 is connected to an electrical wire to supply power to the internal load from an external power source. Because all four pins are electrically connected to the independent meter 5, the independent meter 5 replaces the billing function of the single-phase meter 1, calculating the power consumption of the internal load during the replacement of the single-phase meter 1.

[0035] In this embodiment, both the first conductive pin 32 and the second conductive pin 42 can be inserted into and fixed in the socket 6. In actual use, when the first conductive pin 32 and the second conductive pin 42 are inserted into the socket 6, they need to be firmly inserted to prevent them from falling out and to reduce the risk of electric shock to workers who are replacing meters.

[0036] Example 2:

[0037] like Figures 1-3 As shown, based on Embodiment 1, mounting bases 7 are provided on both the left and right sides of the housing 21. In actual use, the mounting bases 7 are used to fix the housing 21 to the force-bearing surface, and the housing 21 is usually fixed below the single-phase meter 1.

[0038] In this embodiment, the housing 21 has an opening for the first conductive piece 24 to move. In actual use, when the spring 22 is subjected to an external force and contracts inward, the first conductive piece 24 will move inward along with the connecting piece 23. Accordingly, the housing 21 needs to have an opening for the first conductive piece 24 to move, to ensure the normal operation of the first conductive piece 24 and prevent its wiring from coming loose.

[0039] In this embodiment, the connector 2 further includes an insulating gasket 8, and the spring 22 is fixedly connected to the inner wall of the housing 21 and the connecting piece 23 respectively through the insulating gasket 8. In actual use, the insulating gasket 8 prevents the housing 21 from becoming electrified, thus avoiding safety hazards to workers.

[0040] All technical features in this embodiment can be freely combined according to actual needs. The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
