Description
Technical Field
The invention relates to an ammeter mounting seat, in particular to a novel low-voltage uninterrupted ammeter changing plug-in base.
Background
With the continuous progress of scientific technology, the quality and the precision of the current electric energy meter are higher and higher, the metering lean management requirement of the national network company is higher and higher, and higher requirements are provided for the use and the later operation and maintenance of the metering electric energy meter. However, each electric energy meter always has a certain service life, and after the electric energy meters are operated for many years, certain hidden dangers also exist, so that the national network company needs to replace new electric energy meters every few years at present. In addition, when the electric energy meter suddenly breaks down, the electric energy meter needs to be replaced as soon as possible, so that the normal electric quantity metering of a user is guaranteed.
Aiming at resident users, the current meter replacement adopts a power failure operation mode of firstly disconnecting a meter box inlet wire switch, then replacing an electric energy meter and then recovering power transmission, the power failure operation mode is long, the time for replacing one meter is about 10 minutes, and the power failure of users who do not replace meters in the same meter box can be caused. At present, in part of field conditions, before the electricity meter is replaced, rural residents are temporarily informed of the fact that power failure occurs, and the residents in a family are made to be prepared properly, but most of the situations are that no people exist in the family, or a centralized meter box is arranged in a city district, and the residents cannot be informed of the fact that power failure occurs next to the family, so that the electricity meter is replaced in a sudden power failure mode. The power failure problem of most public distribution transformers is solved by interconnection among distribution lines and dual power supply, and no effective solution is provided for the power failure problem at the end of a user caused by replacement of an electric energy meter.
Under the large background that the requirements of vast power users on power supply reliability are higher and higher, meter replacement and power failure seriously affect the quality of power supply service, influence good power consumption experience of users and even cause damage to electrical equipment of the users. In fact, no matter which electric appliance product is suddenly powered off, although the self-protection function of the existing electric appliance is already very perfect, the damage caused by any sudden situation cannot be guaranteed by 100%. The computer and the refrigerator are the most easily damaged because the refrigerator is suddenly powered off when in work, the compressor is in a high-pressure state, and if the compressor is started in the high-pressure state and works in a secondary power-on mode within a short time, the compressor is easily burnt out. Similarly, after a sudden power failure, a sudden incoming call can generate surge current, a computer mainboard is easily burnt out, the saved important data query is lost, even some large files are damaged due to sudden power failure, the files cannot be opened again, and much time and energy are needed to be manufactured again. In addition, when frozen and refrigerated foods are placed in the household refrigerator, the preservation quality of the foods can be seriously affected after power failure, even the foods in the full refrigerator are scrapped, and great economic loss is caused to users. In summary, the power outage can seriously lead to the electricity consumption experience of residents, the power obtaining feeling of the operator environment is poor, and the user claims or directly complains may be caused. Therefore, the realization of meter changing without power outage for the families of residents is urgent.
On the other hand, for a metering and assembling person, the screw driver is required to detach the four screws and the fixed screws of the lead at first every time of replacing the electric meter, then the four screws and the fixed screws are required to be screwed down again when a new electric meter is installed, and the time of informing a user of power failure in the early stage is added, so that the whole meter replacing time is about 10 minutes. Along with the continuous expansion and development of cities, the number of residential areas is increased year by year, so that the number of residential electric meters is increased, and potential failure rate hidden dangers and metering accuracy of the electric energy meters are greatly reduced after the electric energy meters are used for a certain period. At present, about 5 thousands of single-phase electric energy meters are operated in a coastal sub-center, about 2 thousands of single-phase electric energy meters are resident in a residential area under construction, the number of the single-phase electric energy meters is about 20% of the total amount of the single-phase electric energy meters in turn each year, the number of the single-phase electric energy meters in turn and faults is about 1.4 thousands of the single-phase electric energy meters in turn each year, the number of the single-phase electric energy meters in turn. Under the condition that other additional work tasks are increased or decreased, the working pressure of the measurement team is increased, the working quality is reduced, and lean indexes are seriously influenced. Therefore, if the rapid meter changing can be realized, the time consumed in the meter changing process is greatly shortened, the workload of the staff can be undoubtedly reduced, and the working efficiency of the staff is increased.
