Description
Technical field
The utility model relate to intelligent electric meter with the use of intelligent electric meter actuator, being specifically related to a kind of energy-saving mechanism for coordinating electromagnetism close/open machine to use in intelligent electric meter actuator, belonging to low-voltage electrical apparatus attachment technique field.
Background technology
Intelligent grid refers to the intellectuality of electrical network, its objective is and a full automatic electric power transmission network is provided, can each user of monitoring and controlling and grid nodes, ensure the two-way flow of information from power plant to terminal use in whole power transmission and distribution process between all nodes and electric energy.
Intelligent electric meter is the intelligent terminal of intelligent grid, it has not been traditional ammeter, intelligent electric meter is except possessing the function of measuring of traditional ammeter basic electricity amount, in order to adapt to intelligent grid and new forms of energy use it also there is the intelligentized function such as bidirectional data communication function, anti-stealing electricity function of two-way multiple rate function of measuring, user side controlling functions, plurality of data transmission modes, intelligent electric meter represents the developing direction of following energy-conserving intelligent electrical network end user intelligent terminal.
Intelligent electric meter needs to be equipped with intelligent electric meter actuator and jointly uses, and at present, conventional intelligent electric meter actuator is miniature circuit breaker, when subscriber arrearage, intelligent electric meter sends separating brake instruction to miniature circuit breaker, and miniature circuit breaker performs separating brake, thus carries out power-off to defaulting subscriber.By the use of intelligent electric meter and actuator, achieve the prepaid billing mode of electric power, thus solve the problem of traditional manually visit counting cost by gas meter difficulty and frequent defaulting subscriber's difficult charge.
But, adopt miniature circuit breaker as intelligent electric meter actuator still suitable backwardness, its defect is: recharge in electricity card as defaulting subscriber and inserted after intelligent electric meter by electricity card, miniature circuit breaker can not realize automatic closing and restore electricity, but responsible electrician must be found to open ammeter box, manually actuator is closed a floodgate, so can not realize full automation, hinder intelligent grid development and promote.
In order to solve the problem, a kind of intelligent electric meter actuator has been there is in prior art, it comprises the miniature circuit breaker with short circuit overload protection is main switch, be equipped with the microminiature Intelligent electric behaviour with microprocessor, when subscriber arrearage, intelligent electric meter sends instruction and grasps to Intelligent electric, and Intelligent electric behaviour action drives main switch separating brake, realizes power-off; When subscriber payment and again after plug-in card, intelligent electric meter sends instruction again and grasps to Intelligent electric, Intelligent electric behaviour counteragent drives main switch automatic closing, recovers customer power supply.
By the setting that Intelligent electric is grasped, the intelligent electric meter actuator of the prior art is made to have possessed automatic reclosing function, thus intelligent electric meter user is recharged and electricity card is inserted into actuator meeting automatic closing after in intelligent electric meter, and remove to open ammeter box manual closing operation again without the need to responsible electrician, substantially increase efficiency and save artificial, being conducive to development and the popularization of intelligent grid.
