Further, being first in the vertical some reactive compensation modules arranged of drawer type electrically connects through a kind of mode in copper bar bending, soft bus or the cable and said switch with knifeshaped fuse.
Further, be provided with the some offside crossbeams that are used to support said some reactive compensation modules in the said cabinet, every offside crossbeam separately is positioned at the relative both sides of said cabinet.Each reactive compensation module also is provided with some circular position blocks, and every offside crossbeam offers the circular hole that is used to install said some circular position blocks.
Further, said low-pressure reactive compensation cabinet also is provided with lightning arrester, and an end of said lightning arrester is electrically connected on the said fuse of said some reactive compensation modules, the electrical ground connection of its other end.
Further, said low-pressure reactive compensation cabinet also is provided with the current transformer that plurality of parallel is provided with, and one of them current transformer is electrically connected between said switch with knifeshaped fuse and the said fuse.
Compare with conventional art, the beneficial effect of the low-pressure reactive compensation cabinet of the utility model is: irrelevant with the cabinet type, and can be easily supporting with various cabinet types; Composite assembly uses reactive compensation module as playing with building blocks, and can be combined into various capacity and progression as required; Interface is simple, and reactive compensation module has relatively independent system of one's own, and two interfaces---electrical network interface and control interface externally are provided, and the reactive power compensator of with off resonance reactance has been save complicated calculating and design especially; Compact conformation, the more traditional fixed installation of single cabinet capacity increases at least one times.

。Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please consult Fig. 1 and Fig. 2 in the lump, low-pressure reactive compensation cabinet 100 comprises cabinet 10 and is arranged on some reactive compensation modules 20 of cabinet 10 inside, switch with knifeshaped fuse 1, some current transformers 2 and idle compensating control 30 and lightning arrester 3.In this execution mode, the quantity of reactive compensation module 20 is four, and the quantity of current transformer 2 is three.
Each reactive compensation module 20 is integrated with fuse 4, thyristor 5, filter reactor 6, is three electric capacity 7 that triangular form connects.One end of filter reactor 6 is electrically connected between any two electric capacity in three electric capacity 7, and the other end of filter reactor 6 is electrically connected to fuse 4 via thyristor 5.Reactive compensation module 20 is arranged to integration module, and is drawer type and vertically is arranged in the cabinet 10.Adopt copper bar plate 40 to electrically connect between the reactive compensation module 20, idle compensating control 30 is via wherein one and be electrically connected on the fuse 4 of reactive compensation module 20 in switch with knifeshaped fuse 1, three current transformers that are set up in parallel 2.One end of lightning arrester 3 is electrically connected on the fuse 4 of reactive compensation module 20, the electrical ground connection of its other end.Idle compensating control 30 possesses perfect demonstration, control, defencive function.
Being first in the vertical some reactive compensation modules 20 arranged of drawer type electrically connects through a kind of mode in copper bar bending, soft bus or the cable and switch with knifeshaped fuse 1.Be provided with the some offside crossbeams 21 that are used to support some reactive compensation modules 20 in the cabinet 10, every offside crossbeam was opened the relative both sides that are positioned at cabinet 10 in 21 minutes.Each reactive compensation module 20 also is provided with some circular position blocks (figure does not show), and every offside crossbeam offers the circular hole (figure does not show) that is used to install said some circular position blocks.
In sum; The reactive compensation module self-organizing system can be like independent assortment as playing with building blocks, increase-volume, subtract hold very convenient; The device such as fuse, thyristor, filter reactor, electric capacity that it includes assembled has overcome scattered, the awkward problem of conventional mounting.Each reactive compensation module externally provides two interfaces: electrical network interface and control interface, thereby handled easily.
