Abstract
The utility model discloses a non-outage device for changing an electric energy meter, which comprises a circuit breaker, wherein the circuit breaker is connected with two incoming wires and two outgoing wires. The non-outage device for changing the electric energy meter has the advantages that a complex link of publishing an ''outage notice'', which takes most time and is most uncontrollable, before the electric energy meter is set is omitted by the non-outage device in a mode of replacing the electric energy meter under the non-outage status, so that operation personnel can directly enter the working status when arriving at the field and do not need to firstly confirm whether the outage notifying work is implemented, the worry of trouble in the rear that clients make a complaint because of feeling dissatisfied is relieved, and the working efficiency is improved. The wiring protector has the characteristics of convenience in manufacturing, low construction cost, simplicity in operation, convenience in carrying, safety and reliability, the operation maintaining cost can be saved for power supply enterprises, and the time limit for setting the meter in turns is shortened. Although no charging is performed because of directly bypassing the meter during meter setting in the non-outage mode, normal electric quantity loss is caused for the client if the meter is set in an outage mode, and the social benefit created by the meter setting in the non-outage mode and good evaluations from client can not be measured by the electric quantity.

Background technology
The electric energy meter cycle by turns and the professional mileometer adjustment of change electricity consumption all need the operation that has a power failure in short-term to the client; Because the client has relatively high expectations to uninterrupted power supply, inform work though carry out by all kinds of means to have a power failure, but some client do not have " power off notifying " advance notice of going or staying meaning power supply department in advance; The customer information archives are incomplete in the power marketing system; Telephone number change is frequent, and client's multiple uncertain factor such as fail in time to receive calls causes the client not know the operation that has a power failure.Be exactly always the client thinks that the power supply department power failure is wrong, the power failure of power supply enterprise is felt dissatisfied, exists than the big customer thus and complain risk.Need prior notice client time and effort consuming before the power failure operation, it is on the low side to cause the electric energy meter cycle to rotate and change the professional mileometer adjustment operating efficiency of electricity consumption, notifies more than the used time ratio actual job time of client.
The utility model content
The purpose of the utility model is to provide a kind of electric energy meter to change the table device that do not have a power failure, and can effectively solve needs when prior art need be changed electric energy meter to have a power failure, and influences the problem of the normal electricity consumption of client.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme: a kind of electric energy meter changes the table device that do not have a power failure, and comprises circuit breaker, is connected to two inlet wires and two outlets on the said circuit breaker.
Preferably, said circuit breaker is parallel with the Miswire determining device, and said Miswire determining device is provided with acoustic-optic alarm; Prevent to connect anti-line the normal electricity consumption of client is impacted, remind the staff simultaneously.
Preferably; Also comprise protection relay; The control switch of said protection relay and circuit breaker series connection, said Miswire determining device is parallelly connected with the control switch and the circuit breaker of protection relay, and the breaking coil of said protection relay links to each other with the Miswire determining device; Occurring connecing under the situation of anti-line, can open protection outage automatically.
Preferably, also comprise disconnecting relay, the control switch of said disconnecting relay is connected with circuit breaker, and the switch of said disconnecting relay is also connected with the Miswire determining device; All normally restart the connection circuit down in all situation, further improve the wiring fail safe.
Preferably, be connected with voltmeter in the said outlet; Whether normal, have or not the situation of loose contact if observing output voltage.
Preferably, the end of the end of said inlet wire and outlet all is connected with wire clamp; Make things convenient for fast-wiring, increase work efficiency.
Compared with prior art; The utility model has the advantages that: saved " power off notifying " this road before the mileometer adjustment through the mode of using this device to carry out not have a power failure replacing table meter and accounted for time, least controlled numerous and diverse link most; Make the operating personnel once can directly getting into operating state and need not to confirm earlier whether the power failure work of informing puts in place to the scene; Remove the discontented trouble and worry of complaining of client, improved operating efficiency.And the wiring protector has simple for production, cheap, simple to operate, easy to carry, safe and reliable characteristics; Can be power supply enterprise and practice thrift operation expense; Shorten the mileometer adjustment time limit by turns; Mileometer adjustment is not directly chargeed around table though do not have a power failure, and adopts the power failure mileometer adjustment can cause the normal power loss of client yet, and good evaluation of social benefit that the mileometer adjustment that do not have a power failure is created and client can't be weighed by power consumption.
