Description
Technical field
The utility model relates to electrical engineering technical fields, and in particular to a kind of electric power inspection shaft composite monitoring device.
Background technique
Intelligent distribution network is the important component of unified strong smart grid, be related to China's power grid it is intelligent whether
It can smoothly realize.Due to a variety of causes of electric power industry development in history, the development of China's power distribution network obviously lag behind power generation,
Transmission of electricity.95% or more user's power failure at present is caused by distribution system reason, and power grid has the loss of about half to occur in power distribution network, I
Automation, intelligence degree and the self-healing of state's power distribution network and optimization service ability are far below power transmission network, so building intelligence as early as possible
Energy power distribution network is the task of top priority of current smart grid construction.
In the long run, intelligent distribution network by be the following smart grid core, a large amount of distributed generation resources, energy storage, intelligence
Ammeter and user gateway etc. access power distribution network, so that smart grid possesses a large amount of dispersed intelligence node, to promote intelligent electricity
Net develops to distributed direction, formed reticular structure, the multidirectional flowing of energy distributed intelligence power grid, with adapt to these power supplys and
The access of user, and efficient, reliable, high-quality, market-oriented power supply is provided.Therefore following intelligent distribution network system will be collection
The energy supplying system that Chinese style and distributed system organically combine, forming intelligent distribution network in a distributed manner is primary power distribution, power supply and city
Fieldization mode, the unification combined in conjunction with the links such as intelligent centralized power generation, long distance power transmission backbone network, intelligent dispatch
Body.
It is transitioned into following distributed intelligence power distribution network from existing power distribution network, needs to be widely applied sensing, measurement, letter
Breath, the communication technology realize the perception to distribution Running State, then need physical network, intelligent electric to set the control of power grid
Standby, control equipment etc. is realized, is realized distributed intelligence power distribution network and is supported distributed energy access and with power information pipe
Reason, sensor and sensing network provide the technical support on basis thus.
Electric power inspection shaft comprehensive monitoring sensor generally uses the wireless sensing skill based on technologies such as Internet of Things, GPRS at present
Art.Internet of Things generally uses ZigBee communication technology, ZigBee inspection shaft monitoring sensor include: well lid displacement monitoring sensor,
