Description
Technical field
The present invention relates to field of electrical equipment, and in particular to a kind of concentrator for realizing RCD monitoring
Remote communication module.
Background technology
With the construction and development of power network, platform area RCD is widely used.Because power network is multi-point and wide-ranging
And the reason such as aging circuit, cause distribute-electricity transformer district RCD tripping operation frequent, operation maintenance personnel is needed after tripping operation
It could be closed a floodgate to scene.Need to notify operation maintenance personnel after tripping, operation maintenance personnel can just arrive execute-in-place.From tripping to O＆M people
During member carries out closing operation, time-consuming, and inconvenience is brought to user, causes customer complaint, while many residual currents are moved
Make protector artificially out of service, there are a large amount of potential safety hazards, the management and good service to Utilities Electric Co. of basic unit are brought greatly
Pressure, monitored so being badly in need of a kind of effective mode and RCD being realized, existing turnkey console area
The mode of equipment is increase hardware communication device, causes cost to increase, and causes the wasting of resources, the problems such as installing complicated.
At present, each Utilities Electric Co.'s ammeter collection is just in Large scale construction, and many place particularly state's nets have been basically completed,
Realize collection of the department of the identical responsibility such as sales department by concentrator devices to ammeter.But, the accurate collection of state's net, southern network mark
Concentrator in middle kilowatt meter reading-out system can only connect user with main website is adopted, and realize the remote collection of ammeter data.Fortune can't be realized
Inspection etc. department liable platform area temperature and humidity monitor, turnover wiretap, arrester, the quality of power supply regulation etc. the data acquisition of equipment and
Monitoring, the tentative programme of each Utilities Electric Co. is increase distribution transformer terminals TTU to realize, but cost is high, difficulty of construction big, safeguard into
This is big, while marketing and O＆M department etc. need each to safeguard set of system and equipment, workload is big, as each Utilities Electric Co. is sought
Pin and the insertion of Yun Jiandeng departments, the requirement of unification, are solved in the urgent need to a kind of reliable scheme.
In addition, other tables of water, heat, gas are all manually to make a copy of, substantial amounts of human resources are taken, it is also desirable to which one kind can be concentrated
The equipment that device is made a copy of.
In addition, remote communication module matches with current communication network, for example, existing concentrator is internally integrated 2G and led to
Believe module.With the transition in epoch, the development of technology, communication network is constantly updating, and for example, existing 4G is used as 3G's
Upgrade version, its theoretical transmitting data can reach 100MBPS, and 4G has the necessity for replacing 2G, 3G, and 2G, 3G will have becoming for logout
Gesture.In order to adapt to the form that this technology is constantly updated, national grid and south electric network concentrator are also being concentrated by changing
2G concentrators are upgraded to 4G by the mode of device, and existing concentrator is upgraded, it is necessary to will entirely concentrate to be done to its communication network
Device changes the concentrator of support respective communication network into, using this kind of mode, its costly and wasteful resource.
