Embodiment 1

[0022] Embodiment 1: A device for quickly replacing an electric meter, such as figure 2 As shown, it includes clamp body, shorting device 8, screw, screwdriver, current detection device, insulating cover and bump. The clamp body includes upper cover 1 and lower cover 2, and upper cover 1 and lower cover 2 pass through bolt 3 connection, the side corresponding to the upper cover 1 and the lower cover 2 is provided with several semicircular through holes 4, and the lower cover 2 is provided with several semicircular wire holes 5 matching the semicircular through holes 4, and the semicircular The through hole 4 and the semicircular wire hole 5 form the clamping part of the electric meter wire, and the clamp body is installed on the electric wire through the clamping part, such as figure 1 As shown, the upper end of the upper cover 1 is provided with several screw holes, the screws match the screw holes, the current detection device is installed on the screwdriver, the screw is t...

Embodiment 2

[0024] Embodiment 2, a device for quickly replacing an electric meter. Compared with Embodiment 1, this embodiment differs in that the screw includes a head and a screw, the head is fixedly connected to the screw, and the contact surface between the screw and the electric wire is provided with a single Notch, all the other structures are with embodiment one. Twist the screw with a screwdriver, so that the screw of the screw rotates and enters the screw hole, and the insulation of the wire is torn through the front end of the screw with a single notch, so that the screw is in contact with the energized copper wire. At the same time, the single notch is easier to tear Insulation and less wear on live copper wires.

[0025] In a specific application, when the power grid staff needs to replace the electric meter of the power grid user, the lower cover 2 of the present invention is aligned with the wires connected to the electric meter, and the four semicircular wire holes 5 provid...

Abstract

The invention discloses a device for quickly replacing an electric meter, which includes an electric wire, a wire clip body, a shorting device, a screw and a screwdriver. The wire clip body is installed on the wire, and the wire clip body is provided with a screw hole. The screw is installed in the screw hole, and the wire is broken by twisting the screw, so that the screw is in contact with the energized copper wire. The clamp body is provided with a user-side wire loop interface on one side of the screw hole. The contact piece is electrically connected to the screw hole, and the short-circuit device is matched with the user-side wire circuit interface for installation. The invention uses the clamp body and the short-circuit device to realize the continuous power replacement of the electric meter, which is convenient and fast, and reduces the replacement cycle of the electric meter, so that the grid user can use electricity normally during the electric meter replacement process. When the screw is moved, the connection between the screw and the wire is intuitively displayed by reflecting the magnitude of the current, so as to ensure that the short-circuited power circuit meets the user's power demand.

Description

technical field [0001] The invention relates to the field of electric meter wiring clip equipment, in particular to a device for quickly replacing electric meters. Background technique [0002] At present, the power grid company will set up an electric meter for each user of the power grid to record the electricity consumption of the user, but the electric meter is easily damaged under long-term sun and rain, and needs to be replaced once a year to ensure the good operation of the equipment. When replacing the ammeter, since the current backflow connected to the ammeter box cannot be opened, it is necessary to cut off the power to carry out the work. During the power-off operation, the user cannot provide normal power supply, which has brought great trouble to the user. , and at the same time, because the replacement amount involves thousands of units, the quantity is huge, and the scope, time, and cycle of power outages caused are also very large. Therefore, it is necessary...
