Description

[Technical field]

[0001] The invention relates to a wiring device for replacing an electric energy meter without power outage, belonging to the technical field of wiring devices. [Background technology]

[0002] Smart meters are smart terminals of smart grids. They are no longer traditional electricity meters. In addition to the basic electricity consumption metering function of traditional electricity meters, in order to adapt to the use of smart grids and new energy, smart meters also have two-way multi-rate metering function, user-side control function, two-way data communication function with multiple data transmission modes, anti-electricity theft function and other intelligent functions. Smart meters represent the development direction of intelligent terminals for end users of future energy-saving smart grids.

[0003] Since smart meters play an important role, they need to be operated and maintained frequently. Energy meter rotation is an important part of energy meter operation and maintenance. The State Grid needs to undertake the task of rotating single-phase smart energy meters every year. Traditional single-phase smart energy meter rotation requires stopping the user's electricity consumption. This working method has the following disadvantages: (1) It affects the normal electricity consumption of residents, which may cause users to refuse to replace the energy meter; (2) It is easy to cause customer complaints. Power outages for meter replacement affect residents' electricity consumption. Every year, there are many customer complaints related to power outages for meter replacement; (3) It increases the rotation cost and affects the rotation efficiency. Before the rotation, the staff needs to communicate with the user about the power outage, and users who need power outages for meter replacement within a specific time need staff to visit them; (4) There is a quality risk. Power outages for meter replacement involve the removal and connection of the energy meter wiring, which may cause quality hazards. [Summary of the invention]

[0026] like Figure 1As shown, this embodiment shows a wiring device for replacing an electric energy meter without power outage, including a base 1 for installing the electric energy meter, a connecting seat 11 is provided at the lower end of the base 1, a terminal 13 for connecting the electric energy meter is provided on the upper side of the connecting seat 11, a wiring hole for connecting the line is provided on the lower side of the connecting seat 11, a connecting plate 12 is provided in the connecting seat 11, two short-circuits 122 are provided on the connecting plate 12, a first screw 121 is provided in the connecting seat 11, a through hole for the first screw 121 to pass through is provided in the connecting plate 12, a first nut matching the first screw 121 is provided in the through hole, a first knob is provided on the surface of the connecting seat 11, and the first A knob is fixedly connected to the first screw 121, and the first knob is rotated to control the rotation of the first screw 121. The rotation of the first screw 121 drives the connecting plate 12 to move closer to or away from the line, so that the short-circuit 122 is connected to the line. In addition, in this embodiment, two guide rods 123 are provided in the connecting seat 11, and the connecting plate 12 is provided with a through hole for the guide rod 123 to pass through. The two guide rods 123 are arranged on both sides of the first screw 121. When the first screw 121 drives the connecting plate 12 to move, the two guide rods 123 can guide the movement of the connecting plate 12, thereby preventing the connecting plate 12 from deflecting during the movement.

[0027] In this embodiment, the electric energy meter is installed on the upper side of the connecting base 11 and is connected to the terminal 13. The line is inserted into the wiring hole on the lower side of the connecting base 11 to achieve connection with the electric energy meter. The first screw 121 rotates to control the connection plate 12 to approach or move away from the line. When the electric energy meter needs to be replaced, the staff rotates the first screw 121 to control the connection plate 12 to approach the line, so that the short-circuit 122 is connected to the line to achieve short-circuiting of the line, so that the staff can replace the electric energy meter without power outage.

[0028] In addition, in this embodiment, a cover plate for hiding the first knob is provided on the connecting base 11, and a door locking device is provided on the cover plate. When replacing the electric energy meter, the staff needs to first open the cover plate before turning the first knob, which can avoid the user turning the first knob by himself to achieve the short-circuit of the line by the short-circuiter 122. Secondly, an indicator light is provided on the upper surface of the connecting base 11. When the short-circuiter 122 is connected to the line, the indicator light lights up, so that the staff can intuitively determine whether the line is short-circuited, and further ensure that the replacement of the electric energy meter is carried out without power outage.

[0029] In this embodiment, both sides of the base 1 are provided with slide grooves 14, and a slide rod 141 is installed in the slide groove 14. A first return spring 145 is provided at the bottom of the slide rod 141. A clamping device for fixing the electric energy meter is provided on the slide rod 141, and the clamping device includes a fixed clamp 144 and a sliding clamp 143. The fixed clamp 144 is fixedly installed at the bottom of the slide rod 141. A second screw is rotatably arranged in the slide rod 141, and the sliding clamp 143 is sleeved on the slide rod 141. A second nut matching the second screw is provided on the sliding clamp 143, and the rotation of the second screw controls the sliding clamp 143 to move along the length direction of the slide rod 141. A second knob 142 is provided on the top of the slide rod 141, and the second knob 142 is fixedly connected to the second screw. The rotation of the second knob 142 controls the rotation of the second screw.

[0030] In this embodiment, when the staff installs the electric energy meter, the staff fixes the electric energy meter on the base 1 through the clamping device, and then moves the sliding rod 141 to make the electric energy meter close to the terminal 13, so that the electric energy meter can be connected to the terminal 13, wherein a limiting device 15 is provided at the bottom of the sliding groove 14, and when the sliding rod 141 moves to the bottom of the sliding groove 14, the limiting device 15 fixes the sliding rod 141, thereby realizing the connection between the electric energy meter and the terminal 13, so that the staff can install the electric energy meter more conveniently and quickly.

[0031] In this embodiment, a limiting device 15 for fixing the slide rod 141 is provided at the bottom of the slide groove 14, and the limiting device 15 includes a clamping plate. A rotating shaft is provided in the slide groove 14, and the clamping plate is rotatably connected to the rotating shaft. The clamping plate is provided with a clamping head, and a clamping groove cooperating with the clamping head is provided at the bottom of the slide rod 141. The end of the clamping plate away from the clamping head is located below the connecting plate 12, and the end of the clamping plate away from the clamping head is provided with a second reset spring. When the short-circuit 122 is connected to the circuit, the connecting plate 12 controls the limiting device 15 to release the slide rod 141.

[0032] When the staff needs to replace the electric energy meter, the first screw 121 controls the connecting plate 12 to be close to the line to short-circuit the line. At this time, the end of the connecting plate 12 presses the end of the clamping plate to make the clamping plate rotate around the rotating shaft. At this time, the clamping head is away from the sliding rod 141, and the clamping plate releases the restriction on the sliding rod 141. The sliding rod 141 slides upward under the action of the first return spring 145, so that the electric energy meter is separated from the terminal 13, thereby realizing the rapid disassembly of the electric energy meter and improving the speed and efficiency of the staff in replacing the electric energy meter. When the staff reinstalls the new electric energy meter, the first screw 121 controls the connecting plate 12 to be away from the line. At this time, the connecting plate 12 releases the pressure on the clamping plate, and the clamping plate rotates under the action of the second return spring, and the clamping head can be engaged with the slot on the sliding rod 141, so that the clamping plate can fix the sliding rod 141, and the electric energy meter can be connected to the terminal 13.

[0033] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
