Embodiment
As shown in Figure 1, 2, a kind of for stablizing line voltage and reactive power compensating apparatus, comprise the fixedly reactive power compensation filter TFC1 and the sub-GAP TYPE magnet controlled reactor of the adjustable economize on electricity MCR2 that are connected in parallel on respectively in the electrical network; TFC1 is used for providing the required maximum reactive power of electrical network and filtered power; MCR2 regulates reactive power according to electrical network is actual required.
In the specific embodiment, MCR2 adopts single-phase two pillars or three-phase three-limb core structure; Incorporate the electrical adjustment coil in the main iron core of MCR2 into, electrical adjustment coil 3 connects electronics DC power supply 4; The last lower core 5 of MCR2 is C shape or M shape, and middle iron core 6 is rectangle.
Like this, TFC1 provides the required maximum reactive power of electrical network and filtered power, and MCR2 regulates according to the actual required reactive power of electrical network, to reach stable line voltage, the reactive power compensation purpose; Simultaneously, provide perception and the capacitive power of needs, MCR2 perception to cause the line voltage landing at any time according to net voltage fluctuation, the TFC1 capacitive causes that line voltage promotes; This novel device is connected in parallel between electrical network and the load, has realized burning voltage and reactive power compensation effect.
Particularly, MCR2 adopts single-phase two pillars or three-phase three-limb core structure, in main iron core, incorporate electrical adjustment coil 3 into, make its place iron core magnetic flux change play the main iron core air gap can to regulate thereby feed direct current in 4 pairs of electrical adjustment coils 3 of electronics DC power supply, to reach the adjustable program of reactance value; TFC1 provides capacitive, and the sub-GAP TYPE magnet controlled reactor of adjustable economize on electricity provides perception to be connected in parallel in the electrical network; After core structure improved, magnet controlled reactor volume and weight decline 20-30% had saved permeability magnetic material and electric conducting material in large quantities.The utilization of resources is environmental protection more more rationally, and manufacturing cost descends significantly, makes its application more extensive.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
