Description

Technical Field

[0001] The present invention relates to the technical field of power supply, and in particular to a method for replacing an electric meter without power outage. Background Art

[0002] Electricity meter failures, especially those used by farmers in rural areas, are generally caused by burned-out terminals, requiring replacement. This is mainly due to the high use of rigid aluminum wire in rural areas, which has high resistance and is prone to loose connections, which can burn out the terminals. Currently, when replacing new meters, the power is turned off before replacement, causing trouble for farmers.

[0003] Energy meters are currently mandatory instruments for electricity metering and are subject to mandatory inspection for legal settlement purposes. Regulations require that these meters be rotated, and periodic calibration is also required for large-scale users and gateway meters. With the rapid development of the national economy and the increasing size of the power grid, the periodic rotation and on-site periodic inspection of energy meters have become large-scale and institutionalized tasks. Currently, meter rotation is performed after a power outage, necessitating the design of a device that allows for meter replacement without power outages.

[0004] Among existing patents, the closest prior art is patent application number CN202020962053.2, titled "A Device for Replacing an Electricity Meter Without Power Outage." The patent discloses that the device is connected to four terminals in the meter, including a first insulating seat, a grid terminal, a second insulating seat, a conductive drainage seat, a meter terminal and mounting post, a spring, and a connecting post. The patent states that the device cannot be removed after replacing the meter and must remain in the distribution box. However, the limited space in current distribution boxes makes it difficult to add these devices, so the patent is not very practical.

[0005] There is also a patent with application number CN202011589744.3, named a device for replacing a meter without power outage. The patent discloses that the device includes a terminal box, in which an incoming terminal, a first incoming terminal, a second outgoing terminal and a switching copper plate are provided; the incoming terminal is connected to the live wire, the first outgoing terminal is connected to the incoming end of the meter, the outgoing end of the meter is connected to the second outgoing terminal, and the second outgoing terminal is connected to the circuit breaker on the user side; one end of the switching copper plate is fixedly connected to the incoming terminal, and the other end of the switching copper plate switches the connection position between the first outgoing terminal and the second outgoing terminal. When the meter needs to be replaced, the other end of the switching copper plate is rotated from the first outgoing terminal to the second outgoing terminal, so that when the meter is replaced, there is no current input to the incoming end of the meter, and the user side is continuously powered and unaffected; the device of this patent needs to be retained in the distribution box, occupying the space in the meter box. It cannot be installed in the existing distribution box, and it also requires replacing a larger meter box, which is not realistic and increases the cost. Summary of the Invention

[0063] The step S3 includes fixing the second clamp assembly 6 on the load-side switch 4 ; and fixing the contacts on the second clamp assembly 6 to the connection terminals of the load-side switch 4 .

[0064] A device for replacing an electric meter without power outage is used to replace an old electric meter 1 with a new electric meter 2. When replacing an old electric meter 1 with a new electric meter 2, the device uses spare soft copper wire to connect and fix the power-side switch 3 and the load-side switch 4 to the new electric meter 2. The device includes a first clamp assembly 5 that is detachably connected to the power-side switch 3 and a second clamp assembly 6 that is detachably connected to the load-side switch 4.

[0065] The first clamp assembly 5 and the second clamp assembly 6 have the same structure. For the sake of simplicity, this application will only describe the first clamp assembly 5.

[0066] The first clamp assembly 5 is provided with a first soft copper wire connecting the incoming live wire terminal 21 with the power supply side live wire terminal 31 and a second soft copper wire connecting the incoming neutral wire terminal 23 with the power supply side neutral wire terminal 32;

[0067] The second clamp assembly 6 is provided with a third soft copper wire connecting the outgoing live wire terminal 22 with the load-side live wire terminal 41 and a fourth soft copper wire connecting the outgoing neutral wire terminal 24 with the load-side neutral wire terminal 42 .

[0068] The first clip assembly 5 includes a clip fixedly connected to the power side switch 3 and a live wire contact 7 and a neutral wire contact 8 installed on the clip; the live wire contact 7 is respectively connected to the power side live wire terminal 31 and the first soft copper wire; the neutral wire contact 8 is respectively connected to the power side neutral wire terminal 32 and the second soft copper wire.

[0069] The clamp includes a left hook 51 with one end in contact with one side of the bottom of the power-side switch 3, a right hook 56 with one end in contact with the other side of the bottom of the power-side switch 3, a left pull rod 52 with one end hinged to the other end of the left hook 51, a right pull rod 55 with one end hinged to the other end of the right hook 56, a cross bar 53 with one end hinged to the other end of the left pull rod 52, a locking bolt 54 threadedly connected to the cross bar 53, and a bottom plate 57 rotatably connected to the end of the locking bolt 54.

[0070] The other end of the right pull rod 55 is hinged to the other end of the cross bar 53;

[0071] The bottom plate 57 abuts against the top surface of the power side switch 3;

[0072] When using the clip, hook the left hook 51 and the right hook 56 onto the bottom of the power switch 3 respectively, and at the same time, use one hand to force the bottom plate 57 against the top surface of the power switch 3;

[0073] By turning the locking bolt 54, the cross bar 53 moves upward under the action of the threaded force of the locking bolt 54, and the cross bar 53 drives the left pull rod 52 and the right pull rod 55 at both ends to move upward, and the left pull rod 52 drives the left hook head 51, and the right pull rod 55 drives the right hook head 56 to move upward at the same time; in this way, the clamp can fix the power side switch 3; similarly, the other clamp is fixed to the load side switch 4.

[0074] The live contact 7 and the neutral contact 8 are mounted on the crossbar 53;

[0075] The power-side live terminal 31 is provided with a screw for fastening the wire. The live contact 7 includes a connection portion 75 that abuts the screw head of the power-side live terminal 31 and an insulating column 76 fixedly connected to the connection portion 75. The insulating column 76 is hollow cylindrical and has a boss 74. The first fixing device abuts the boss 74. The connection portion 75 is connected to the incoming live terminal 21 of the new electric meter 2 via a first soft copper wire.

[0076] The live wire contact 7 and the neutral wire contact 8 have the same structure.

[0077] The detailed technical solution is that the crossbar 53 is fixedly connected to the mounting plate 9; the insulating column 76 is slidably connected to the mounting plate 9;

[0078] The connection portion 75 on the live wire contact 7 vertically passes through the mounting plate 9 and contacts the nut on the screw of the live wire terminal 31 on the power supply side, and conducts current through the first soft copper wire and the incoming live wire terminal 21 of the new electric meter 2;

[0079] The connection portion 75 on the neutral contact 8 vertically passes through the mounting plate 9 and contacts the nut on the screw of the neutral terminal 32 on the power supply side, and conducts current through the second soft copper wire to the incoming neutral terminal 23 of the new meter 2;

[0080] The mounting plate 9 is provided with a first fixing device for fixing the live contact 7 to the live terminal 31 on the power supply side, and a second fixing device for fixing the neutral contact 8 to the neutral terminal 32 on the power supply side. The first fixing device and the second fixing device have the same structure and working principle, so the second fixing device will not be described here.

[0081] The first fixing device includes a column 71 fixedly connected to the mounting plate 9, a pressure plate 73 provided between the column 71 and the boss 74, and a locking nut 72 for pressing the pressure plate 73 against the column 71; one end of the pressure plate 73 is sleeved on the column 71, and the other end of the pressure plate 73 overlaps the boss 74; the pressure plate 73 and the column 71 are loosely fitted; a flange is provided in the middle of the column 71; the upper part of the flange is provided with an external thread, which is threadedly connected to the locking nut 72;

[0082] After the wiring portion 75 passes through the mounting plate 9 (a mounting hole is provided on the mounting plate 9), it abuts against the screw of the live terminal 31 on the power side, and one end of the pressure plate 73 is used to press the boss 74 of the insulating column 76; the other end of the pressure plate 73 is loosely sleeved on the column 71 and supported by the flange, and the pressure plate 73 is fixed with a locking nut 72; the pressure plate 73 can firmly fix the wiring portion 75 to the nut of the screw to facilitate conductivity.

[0083] The second clip assembly 6 connects the connection terminals on the load-side switch 4 to the new electric meter 2 through the third soft copper wire and the fourth soft copper wire respectively.

[0084] The working and use process of this device is as follows:

[0085] The first step is to firmly fix the two clips to the power side switch 3 and load side switch 4 of the old meter 1; the process is as follows:

[0086] Hook the left hook 51 and the right hook 56 onto the bottom of the power switch 3 respectively, and at the same time, use one hand to force the bottom plate 57 to contact the top surface of the power switch 3;

[0087] Turn the locking bolt 54, and the cross bar 53 moves upward under the action of the thread force of the locking bolt 54, and the cross bar 53 drives the left pull rod 52 and the right pull rod 55 at both ends to move upward. The left pull rod 52 drives the left hook head 51, and the right pull rod 55 drives the right hook head 56 to move upward at the same time; in this way, the clamp can fix the power side switch 3;

[0088] Similarly, another clip is fixed to the load-side switch 4;

[0089] The second step is to fix the live wire contact 7 and the neutral wire contact 8 to the mounting plate 9 respectively;

[0090] The connection between the power side live wire terminal 31 of the power side switch 3 and the live wire contact 7 is as follows:

[0091] First, solder one end of the connection portion 75 to one end of the first soft copper wire; secure the other end of the first soft copper wire to the screw of the incoming live wire terminal 21 of the new electric meter 2 with a clamp;

[0092] The other end of the connection part 75 is in contact with the power-side live wire terminal 31 on the power-side switch 3, and the screws of the connection part 75 and the power-side live wire terminal 31 are pressed firmly with the locking nut 72, the pressure plate 73, and the insulating column 76;

[0093] One end of the connection portion 75 of the neutral wire contact 8 is soldered to one end of the second soft copper wire; the other end of the second soft copper wire is fixed to the incoming neutral wire terminal 23 of the new electricity meter 2 with a clip; the other end of the connection portion 75 is fixed to the power side neutral wire terminal 32 on the power side switch 3 through a second fixing device.

[0094] Use the same method to connect the load-side live terminal on the load-side switch 4 to the live terminal 22 of the new meter 2 through the third soft copper wire, and connect the load-side neutral terminal 42 to the neutral terminal 24 of the new meter 2 through the fourth soft copper wire.

[0095] In this way, the new electricity meter 2 can measure normally;

[0096] Finally, remove the old meter 1; install the new meter 2 into the meter box; connect the incoming wire of the load-side switch 4 to the corresponding outgoing wire terminal of the new meter 2; and connect the outgoing wire of the power-side switch 3 to the corresponding incoming wire terminal of the new meter 2;

[0097] At this time, you can remove the first soft copper wire, the second soft copper wire, the third soft copper wire, and the fourth soft copper wire from the new meter 2, and insulate the joints; then loosen the pressure plates 73 respectively, and detach the live wire contact 7 and the neutral wire contact 8 from the terminal screws of the power side switch 3 and the load side switch 4 respectively; remove the clips; pay attention to the insulation protection of the joints in this process to prevent accidents, and the meter replacement without power outage is completed.
