Abstract
The utility model is related to a kind of remote power metering cabinet, including cabinet, kilowatt-hour meter, the relay with GPRS communicating terminals, transformer and primary line are provided with cabinet, having air switch is concatenated on the primary line, the transformer is located on the primary line of the end of incoming cables of the air switch, and the relay is connected by wire with the tripping operation terminal of air switch, in addition to battery, described battery one end connects the relay, and the other end connects the air switch by charger.The utility model has following clear advantage compared with prior art：Battery storage electric energy, after air switch disconnects, is that control circuit and switch provide energy, realizes the operation of remote switching.
Description
Technical field
The present invention relates to a kind of power equipment, and in particular to a kind of electric-power metering cabinet.
Background technology
Remote power metering cabinet is accurate measurement, easy to operate, until increasing effect in electrical management control,
But in use there is also a problem, after air switch is disconnected, electric energy is lost, air switch can only be closed by hand, it is impossible to
Operation.
The content of the invention
The purpose of the present invention is in view of the deficienciess of the prior art, there is provided a kind of remote power metering cabinet.
The purpose of the present invention is realized by following technological means：
Including cabinet, kilowatt-hour meter, the relay with GPRS communicating terminals, transformer and primary line, institute are provided with cabinet
State and having air switch concatenated on primary line, the transformer is located on the primary line of the end of incoming cables of the air switch, it is described after
Electrical equipment is connected by wire with the tripping operation terminal of air switch, in addition to battery, and described battery one end connects the relay, separately
One end connects the air switch by charger.
The present invention has following clear advantage compared with prior art：Battery storage electric energy, after air switch disconnects,
It is that control circuit and switch provide energy, realizes the operation of remote switching.
Brief description of the drawings
Fig. 1 is structure chart of the invention.
Embodiment
