Recently; people have developed a kind of reactive power automatic compensation power supply box; it is installed bus and reactive power Electric capacity compensation device concentratedly in same power supply box; this power supply box can cooperate with outdoor transformer, and the electrical network of distinguishing the power supply of loosing for small pieces provides protection and carries out automatic reactive power compensation.But, above-mentioned power supply box is installed in outdoor, work under bad environment, various components and parts damage easily, in case particularly wherein certain capacity cell damage, the power supply that must cut off whole power supply box overhauls, so not only cause the power failure scope wide, and because power supply box is installed in the outdoor transformer top, maintenance or replacing operation are all inconvenient, make the maintenance or the length consuming time that more changes jobs, therefore corresponding interruption duration is also long.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of reactive power automatic compensation power supply box that is fit to be installed on outdoor environment is provided, and its overhauls or change the easy to operate of capacity cell.
For realizing above purpose, reactive power automatic compensation power supply box of the present utility model comprises by tank wall and surrounds the casing that forms, be provided with bus, reactive power Electric capacity compensation device, current sampling harvester and multiloop air circuit in the casing, be provided with dividing plate in the casing, dividing plate is divided at least three cell compartment with casing, its median generatrix is laid in the first module compartment, the reactive power Electric capacity compensation device is arranged in second cell compartment, and the multiloop air circuit is installed in the 3rd cell compartment; Bus connects the multiloop air circuit, be primarily characterized in that, reactive power Electric capacity compensation device in second cell compartment is made up of several same no-power compensation function unit, each no-power compensation function unit is provided with element and the electric capacity of carrying out reactive power compensation, be provided with several drawer lattice in second cell compartment, each no-power compensation function unit is installed in respectively in the corresponding drawer lattice, the rear end of each drawer lattice is provided with plug spare, plug spare fixedly is connected as a single entity with drawer lattice, the no-power compensation function unit of each drawer lattice forms with the corresponding plug part and is electrically connected, second cell compartment also is provided with some socket piece, each plug spare is plugged in the socket piece to corresponding coupling one by one, and each socket piece is parallel-connected to the bus in the first module compartment.
Realization above-mentioned purpose scheme preferably is: the base plate of described drawer lattice is provided with a plurality of installing holes, and the bolt that installing hole is passed in the element of described no-power compensation function unit and electric capacity utilization is locked on the base plate of corresponding drawer lattice.
Realize that the better scheme of above-mentioned purpose is: each drawer lattice is installed on the guide rail.Can extract out or insert along guide rail like this.
Each drawer lattice two side bottom is provided with can be along the roller of guide rail rolling.
Above-mentioned current sampling harvester can be installed in the 3rd cell compartment, also is installed in the first module compartment.
The 3rd cell compartment of above-mentioned power supply box can also be equipped with the telemonitoring device.
The 3rd cell compartment of above-mentioned power supply box can also be equipped with electric power meter.
The utlity model has following advantage and effect:
1, this power supply box can be connected the transformer low voltage side, reliably, the switching of control capacitor group effectively, load or burden without work is carried out automatic tracking and compensating, make the electric network reactive-load loss control at minimum state, thereby reduce electrical power trans mission/distribution system and transformer loss, arrive energy-saving effect.
2, because each no-power compensation function unit forms relation in parallel, and be connected respectively to bus by plug spare and socket piece separately, can cooperate like this and be used as the function that an integral body is carried out reactive power compensation jointly, can take away independently of one another again and overhaul or change and do not influence other no-power compensation function cell operation, make the wherein maintenance in arbitrary minute loop change the normal power supply that can not influence other loop.
3, adopt drawer-type structure, and adopt plugs and sockets to be electrically connected form between the no-power compensation function unit in the drawer lattice and the bus, make dismounting all very convenient.
4, each no-power compensation function unit and drawer lattice can adopt modularized design, interchangeability is strong, so not only convenient for production, if and in use certain no-power compensation function unit damages, and can take this drawer lattice away, uses another identical spare module then immediately instead, promptly insert the standby drawer lattice that another is equipped with the no-power compensation function unit immediately, so just, finish more changing jobs, whole replacing process only needs 2-3 minute, makes interruption duration extremely short.
