The intelligent integral A.C. distribution box
Technical field
The utility model relates to a kind of distribution box, relates in particular to a kind of intelligent integral A.C. distribution box.
Background technology
Communication base station is divided into by function with distribution box: 1. possess basic distribution electric work can distribution box; 2. the distribution box that possesses basic distribution electric work energy, electric energy metrical, voltage demonstration; 3. the distribution box that possesses basic distribution electric work energy, electric energy metrical, voltage demonstration, lightning protection function; 4. the product of other on-fixed assembly.
Classify by product quality: 1. standard machinery formula electric energy meter, homemade miniature circuit breaker or breaker of plastic casing combination; 2. electronic electric energy meter, import miniature circuit breaker or breaker of plastic casing combination; 3. other nonstandard class combination;
The existing distribution box configuration in base station is relatively more chaotic, profile is inconsistent, and this has brought a lot of inconveniences in the operation and maintenance process.Wherein the lower product of configuration can not satisfy the demand of updating and management, influences the progress and the cost of maintenance work upgrading.Simultaneous potential safety hazard has also caused many accidents and loss, as personnel get an electric shock, circuit is on fire, electric fault or because of the aging device damage that causes of product quality etc.
In addition, the less distribution box of function also caused the secondary transformation when can not satisfy system requirements, the increase of the maintenance work of transforming for three times.Not only increase workload, also increased cost.Such as: distribution box does not possess lightning protection function just need append thunder resisting equipment; There is not the phase sequence translation function just need append the phase sequence transducer; Do not have intelligent electric meter just can not realize remote meter reading, just need to increase the length of run kilowatt meter reading-out system; There is not oily machine timing just can not effectively examine energy output; There is not the civil power dynamic monitoring just not know reason of loop fault or the like; The surface influence of these things can effectively be estimated, but difficult calculating the far away of secondary influence thereafter, because it will influence the management and the construction of the science of system.Such as, the equipment that increases in the transformation process will take the confined space resource of base station; It is too high to be positioned on the residual voltage that the lightning protection device on distribution box next door causes because of wiring is oversize, will influence the lightning protection effect of SPD in this case.Ordinary electric meter can't output pulse signal, can not upload by the rotating ring monitoring, and be realized that by long-distance meter-reading system such two systems can not be compatible, is unfavorable for unified management.
The defective of distribution box is summarised as:
1. functional configuration is incomplete, does not have unified configuration standard.Original system only possesses basic distribution electric work energy.
Lack the dual power supply function, lack electric energy metering separate function, lack the tripping alarm function, lack anti-surge function, lack the automatic remote closing function, lack air-conditioning Long-distance Control handoff functionality, lack data length of run transfer function (remote monitoring function);
2. the product configuration quality is poor, brings the hidden danger (electric shock, on fire) of useful life and high risk and the defective of high maintenance rate.
3. incomplete space resources waste and the construction cost of bringing the secondary transformation to produce of functional configuration increases (construction cost rises, the taking of space resources, maintenance cost rising).
4. functional configuration has not been brought system upgrade and managerial difficulty comprehensively; The management of power use (analysis of power quality analysis, electric energy dosage analysis, energy-saving scheme) can not be realized, the reasonable arrangement of O﹠M work can not be effectively worked in coordination with.
