Abstract
The invention relates to the field of plug-and-play electric energy meters, in particular to a device allowing an electric energy meter to be plugged and unplugged without an outage. The device comprises an electric energy meter base and a meter head. The electric energy meter base is provided with elastic contact elements with different lengths. A current path can be formed by the elastic contact elements when the meter head is not inserted. After the meter head is inserted, the elastic contact pieces of the electric energy meter base are separated by an insulating plate on one side of a meter head binding post, so that the current path of the electric energy meter base is cut off, a current path is composed of the meter head and part of the elastic contact elements of the electric energy meter base at the moment, and the purpose of connecting the meter head is achieved. In the plugging and unplugging process of the meter head, the process that two current paths work at the same time occurs and causes equipotential connection, and the equipotential connection guarantees that the electric energy meter can be plugged and unplugged without the outage and also guarantees that no spark is generated in the plugging and unplugging process. The device has the advantages that plug-and-play of the electric energy meter is realized, and the electric energy meter is as convenient to connect or remove as an electric appliance. The electric energy meter base is of a mechanical structure, so that reliability is high.
Description
Technical field
The present invention relates to plug and play electric energy meter field, it is a kind of device of realizing the continuous hot-line insertion and extraction of electric energy meter.
Background technology
" only stop one second electricity, all can exert an influence to client.Therefore computer data may be lost, and the work of household electrical appliances cut easily causes fault." it is reported, the ammeter that each province changes every year or newly applies to install reaches up to a million, originally changes an ammeter and need have a power failure 10 minutes, and change ammeter without power failure, can make annual power off time reduce 5 minutes.
Along with technical development and managerial promotion, client's power off time declines gradually.In particular cases non-, only change ammeter and just need to stop client's electricity, this has become to be avoided last one obstacle of having a power failure.
For promoting intelligent grid construction, improve the technical merit of intelligent power, formulate the AMI Technical Standard System that faces the future new, reduce client's power off time, advance electric energy metrical intelligent development, research and develop continuous hot-line insertion and extraction, plug and play electric energy meter is imperative.
Summary of the invention
The object of this invention is to provide a kind of reliable, simple in structure, electric energy meter physical construction with continuous hot-line insertion and extraction.
Realize a device for the continuous hot-line insertion and extraction of electric energy meter, the present invention includes gauge outfit and base, gauge outfit and base adopt isolating construction, realize electric energy meter plug and play; Wherein, be provided with resilient contact different in size on base, the resilient contact that is positioned at both sides is longer than the resilient contact that is positioned at inner side; Adopt insulation in gauge outfit binding post one side, opposite side adopts conductor.
Resilient contact different in size has guaranteed that ammeter access is that equipotential is connected with the process of removing, thus guarantee continuous hot-line insertion and extraction, and eliminated the spark in common plug process, thus well protect contact.
Resilient contact on base adopts the good platinoid shell fragment of electric conductivity, adopts screw to be fixed on base, and the shell fragment of long side can increase wire binding post on fixed orifice.Base final molding is as a common plate, and resilient contact is encapsulated in the box the inside of only staying jack, and user does not reach electrified body.
For the current method such as electricity meter, protection against electric shock, base and gauge outfit are all introduced intelligent metering part live wire and zero line.
Beneficial effect of the present invention: be to realize the plug and play of electric energy meter, realize electric energy meter and access easily as electrical appliance or remove.Because adopting physical construction, realizes base, so there is extreme high reliability.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Realize a device for the continuous hot-line insertion and extraction of electric energy meter, comprise gauge outfit and base, gauge outfit and base adopt isolating construction, realize electric energy meter plug and play; Wherein, be provided with resilient contact different in size on base, the resilient contact that is positioned at both sides is longer than the resilient contact that is positioned at inner side; Adopt insulation in gauge outfit binding post one side, opposite side adopts conductor.
As shown in Figure 1, in the present embodiment, structure comprises under casing 5, is fixed on length resilient contact 6 A, 7 B, 8 C under casing, insulation cover plate 1, gauge outfit 2, gauge outfit conductor binding post 4, gauge outfit insulating terminal insulation sides 3.
In the time not inserting gauge outfit, length contact element is due to elasticity but 6 A, 7 B, 8 C are in contact with one another composition current path: resilient contact 8 C---resilient contact 7 B---resilient contact 6 A.
In gauge outfit insertion process, gauge outfit conductor binding post first contacts with longer resilient contact, and current path now has two: resilient contact 8 C---gauge outfit 2---resilient contact 6 A; Resilient contact 8 C---resilient contact 7 B---resilient contact 6 A.
After gauge outfit is inserted, the insulation sides 3 of gauge outfit binding post is separated shorter resilient contact 7 B and longer resilient contact 6 A, only remaining one of current path now: resilient contact 8 C---gauge outfit 2---resilient contact 6 A.Shown in accompanying drawing 2, gauge outfit binding post has been divided into two parts, and conductor side participates in current path, and insulation sides is used for isolating current path.
Base is installed and wiring is loaded on insulation cover plate 1 after completing at resilient contact, and base is now substantially the same with common socket in appearance, and Jian is complete in, reliable, attractive in appearance one.And gauge outfit is as a common electrical appliance, just have two special plugs.
Such design has reached the real plug and play of electric energy meter, has overturned the mode of in the past changing electric energy meter.The table that changes in the future will be safety, convenient, efficient.
