Description

Technical Field

[0001] The present invention belongs to the technical field of electric power equipment, and in particular relates to a non-stop meter replacement device for electric power metering equipment and a use method thereof. Background Art

[0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

[0003] Electricity metering equipment is a metering device used to measure and record power generation, power supply, plant power consumption, line loss and user power consumption. Generally, the replacement of electricity metering equipment requires turning off the low-voltage branch switch or the main switch of the meter box in order to replace the metering equipment. This situation will cause large-scale power outages in the power supply range during the replacement of the metering equipment, affecting the customer's electricity experience.

[0004] The existing patent publication number CN118243979A proposes a three-phase non-stop power meter replacement device, which uses a short-circuit device to set a short-circuit structure that is compatible with the position of the three-phase meter terminal posts of the meter installation shell, so that the meter is short-circuited in advance before replacement to ensure that the power is not cut off when the meter is replaced. However, when the device is used, short-circuiting the three-phase electricity in a short period of time will form a low-impedance path, resulting in a rapid increase in current. This fault may lead to serious consequences. Moreover, the exposed terminal posts are not shielded during the short-circuit period, and there is still current on the terminal posts, which may cause the operator to accidentally get an electric shock. Summary of the invention

[0005] The purpose of the present disclosure is to provide a non-stop meter replacement device for electric power metering equipment and a method for using the device, which can solve at least one of the above-mentioned technical problems.

[0006] To achieve the above-mentioned objectives, one or more embodiments of the present disclosure provide a non-stop meter replacement device for electric power metering equipment, comprising an equipment mounting frame and a splitter, wherein the equipment mounting frame comprises a frame body for mounting an electric meter and a clip-on bracket arranged on the frame body, the top of the clip-on bracket is provided with four groups of terminal posts connected to the electric meter, and the front end of the clip-on bracket is provided with a socket connected to the splitter; the splitter comprises a junction box and two groups of wiring clamps arranged on the junction box, and the junction clamps are plugged into the sockets of the clip-on bracket.

[0007] Furthermore, the terminal blocks are respectively a live wire input terminal, a live wire output terminal, a neutral wire input terminal and a neutral wire output terminal. The live wire input terminal and the live wire output terminal are arranged on the same side, and the neutral wire input terminal and the neutral wire output terminal are arranged on the same side.

[0008] Furthermore, the jacks are provided in two groups, which are respectively provided between the terminals of the same circuit.

[0009] Furthermore, an insulating cover is provided on the top of the junction box, and the insulating cover and the junction box are rotatably connected via a hinge.

[0010] Furthermore, the height of the insulating cover is greater than the height of the terminal post, and the width is greater than the overall width of the junction box and the clamping bracket after being connected.

[0011] Furthermore, an elastic component formed by two groups of semicircular elastic clips is provided at the end of the branching clamp.

[0012] Furthermore, the elastic clips are fixedly connected to the line splitter, and an elastic space is formed between the two groups of elastic clips.

[0013] Furthermore, the width of the elastic component is equal to the diameter of the jack arranged on the clamping bracket, and the binding posts of the same circuit are short-circuited by the elastic component.

[0014] Furthermore, a support plate for placing the junction box is provided at the bottom of the clamping bracket.

[0015] A method for using the above-mentioned non-stop meter replacement device for electric power metering equipment: first, insert the branching clip on the branching device into the socket of the clamping bracket to form a short circuit between the terminals of the same line, then remove the metering equipment to be replaced connected to the terminals, and then close the insulating cover to cover the exposed terminals, and then perform preparations before installing the new metering equipment. After the preparation is completed, open the insulating cover, connect the wiring holes of the new metering equipment to the terminals accordingly, and complete the replacement of the metering equipment.

[0016] The beneficial effects of one or more of the above technical solutions are:

[0017] The present invention ensures that a short circuit is formed between the terminals of the same line by inserting the branching clamp on the branching device into the jack of the clamping bracket. After the old metering equipment is removed, the insulating cover is closed to shield the exposed terminals, thereby preventing accidental electric shock and ensuring the safety of the operator. During the replacement of the metering equipment, the low-voltage branch switch or the main switch of the meter box can be kept on for non-power-off operation. The branching clamp installed on the household line side under low voltage can effectively prevent phase-to-phase short circuit caused by improper operation, thereby ensuring the stable operation of the entire power system.

[0023] like Figure 1-Figure 3 As shown, this embodiment provides a non-stop meter replacement device for electric power metering equipment and a method of use, including an equipment mounting frame 1 and a splitter 2; the equipment mounting frame 1 includes a frame for mounting the electric meter and a clip-on bracket 3 arranged on the frame, and the splitter 2 includes a junction box 11 and two sets of wiring clamps 12 arranged on the junction box 11.

[0024] An elastic component formed by two groups of semicircular elastic clips 13 is provided at the end of the branching clamp 12. The elastic clips 13 are fixedly connected to the branching clamp 12. An elastic space is formed between the two groups of elastic clips 13 to ensure that the elastic clips 13 can be properly deformed so that the elastic clips 13 can be fully inserted into the socket 8. At the same time, the width of the elastic component is completely consistent with the aperture of the socket 8 set on the clamping bracket 3.

[0025] Specifically, Figure 2 and Figure 3 As shown, four groups of terminals connected to the electric meter are provided on the top of the clip-on bracket 3, and the terminals are used to connect to the electric meter, ensuring a stable and safe connection between electrical equipment. A socket 8 connected to the splitter 2 is provided at the front end of the clip-on bracket 3; the splitter clip 12 is plugged into the socket of the clip-on bracket 3, which can ensure the stability and reliability of the connection between the equipment mounting frame 1 and the splitter 2.

[0026] The four groups of terminals on the top of the clip-on bracket 3 are respectively the live wire input terminal 4, the live wire output terminal 5, the neutral wire input terminal 6 and the neutral wire output terminal 7, wherein the live wire input terminal 4 and the live wire output terminal 5 are arranged on the same side, and the neutral wire input terminal 6 and the neutral wire output terminal 7 are arranged on the same side; there are two groups of jacks 8, which are respectively arranged between the terminals of the same circuit.

[0027] The elastic components can easily short-circuit the terminals of the same circuit. This short-circuiting method not only improves the efficiency of wire connection, but also ensures the stability and safety of the connection, thus providing a strong guarantee for the stable operation of the electrical system.

[0028] Specifically, by inserting the splitter clip 12 into the jack 8, the terminals of the same line can be short-circuited, which can solve the problem of phase-to-phase short circuit of household lines when replacing metering equipment in a low-voltage environment. Phase-to-phase short circuit may cause a short circuit in the three-phase power system in a short period of time, forming a low-impedance loop. As a result, the current will rise sharply and cause overload damage to the power equipment.

[0029] like Figure 3 As shown, an insulating cover 10 is provided on the top of the junction box 11, and the insulating cover 10 is rotatably connected to the junction box 11 through a hinge, and the width of the insulating cover 10 is also greater than the overall width of the junction box 11 after being connected to the clamping bracket 3. The insulating cover 10 can completely cover and shield the exposed terminal, so that when the operator replaces the metering equipment, the electric shock accident that may occur due to accidental contact with the terminal is effectively avoided, and the safety of the operation is greatly improved.

[0030] At the bottom of the clamping bracket 3, a support plate 9 is designed to place and support the junction box 11 to ensure the stability and safety of the junction box 11 during use.

[0031] The method of using the above-mentioned meter changing device in this application:

[0032] First, insert the wire splitter 12 on the wire splitter 2 into the socket 8 of the clamp bracket 3 to ensure that a short circuit is formed between the terminals of the same line. In order to prevent electric shock accidents during the replacement process, the metering equipment to be replaced connected to the terminals needs to be carefully removed, and the insulating cover needs to be closed to cover the exposed terminals. Next, the preparation work before the installation of the new metering equipment is carried out, including checking whether the new equipment is intact and whether it meets the installation requirements. After the preparation is completed, open the insulating cover again, connect the wiring hole of the new metering equipment to the corresponding terminal, and ensure that the connection is firm and reliable. Finally, after completing all connections, check the connection of the meter to ensure that all lines are connected normally.

[0033] Although the above describes the specific implementation methods of the present disclosure in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present disclosure. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present disclosure, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present disclosure.
