Description

SVC transformer station reactive compensation complete device
Technical field
The utility model relates to the reactive power compensator that transformer station concentrates, and is specially SVC transformer station reactive compensation complete device.
Background technology
Along with fast growth of national economy, each industry and appliance load increase considerably, and it is serious that the electric load breach is said benefit.The power system voltage reactive management is the important means that guarantees Economical Operation of Power Systems, and strengthening the power system reactive power management can systems stabilisation voltage, improve power factor, reduce line loss.Reasonably the selection of reactive power compensation mode should following several principles: that 1, reduces reactive power flows the principle of local compensation; 2, grading compensation principle concentrates installing to combine with disperseing installing, is main comprehensive planning with dispersion compensation; 3, prevent overcompensation under the underload situation, promptly send reactive power to electrical network.And the most transformer station's fixed capacitor group reactive power compensation modes that adopt of the present power distribution network of China owing to lack idle regulating measure, during the power supply peak valley power factor fluctuation bigger, complementarity problem appearred mending and owing, the quality of power supply has been caused harm.
Summary of the invention
The utility model provides a kind of structure clearly demarcated, easy for installation just at above problem, and floor space is little, the SVC transformer station reactive compensation complete device that cost is low.
Concrete technical scheme of the present utility model is as follows:
SVC transformer station reactive compensation complete device, comprise air core reactor, capacitor, discharge coil, spray-by-type fuse, framework, insulator and lightning arrester, lightning arrester links to each other with insulator, air core reactor links to each other with spray-by-type fuse, spray-by-type fuse links to each other with capacitor, capacitor links to each other with discharge coil, and framework links to each other with discharge coil, and insulator is overlapped on the framework top.
Technique effect of the present utility model shows: satisfying under the situation of national standard, according to transformer capacity and bearing power accurate Calculation compensation capacity, can not occur mending and owe to mend, can remove more than components and parts, components and parts are simplified to the most practical state, the female frame connected mode of utilization electric capacity neutral point, structure is clearly demarcated, easy for installation, floor space is little, and cost is low.

Embodiment
The utility model is described in further detail below in conjunction with embodiment and Figure of description
Embodiment:
SVC transformer station reactive compensation complete device, comprise air core reactor, capacitor, discharge coil, spray-by-type fuse, framework, insulator and lightning arrester, lightning arrester links to each other with insulator, air core reactor links to each other with spray-by-type fuse, spray-by-type fuse links to each other with capacitor, capacitor links to each other with discharge coil, and framework links to each other with discharge coil, and insulator is overlapped on the framework top.
SVC transformer station reactive compensation complete device is connected in parallel on the 35KV bus, by the switch cubicle inlet wire, does to support and the busbar overlap joint by lightning arrester, and discharge coil secondary termination open delta is used as differential voltage protection monitoring and discharge.
The capacitor box switch cubicle closes a floodgate; device puts into operation; capacitor discharges the perceptual reactive current that exists in the capacitive reactive power current compensation circuit; the lightning arrester that inlet wire is installed is as overvoltage protection; after device is cut; discharge coil can drop to voltage below the 50V in 3 minutes; reactor is avoided the damage to capacitor mainly as the anti-anti-harmonic elements that shoves, and rated voltage adopts after two series connection in parallel for the 11KV capacitor; totally 12; therefore bear the system voltage of 35KV, neutral point is connected on the square aluminum row frame, and aluminium row's frame is owing to closely contact with the metal steelframe; so the discharge coil neutral point can directly be overlapped on the framework, this and save installation cost.
