Description
Technical field
The utility model belongs to dynamo-electric manufacturing, particularly a kind of plug type generating set brush carrier.
Background technology
Modern 600MW generating set generally adopts certainly and excitation mode, the direct current that in generator operation, excitation change is desired parameters from the AC rectification that generator outlet obtains by excitation unit, direct current delivers to generator amature winding through carbon brush and collector ring sliding contact, sets up generator magnetic field.And carbon brush is contained in brush carrier, so the whole service operating mode of brush carrier affects the operational effect of carbon brush, in generator operation, friction generates heat for carbon brush and slip ring, its heat is taken away by cooling system simultaneously, carbon brush even slip ring of striking sparks occurs that ring fire compromises the safe operation of unit greatly, carbon brush occurs that sparking has the reason of carbon brush also to have the reason of brush carrier, carbon brush needs to hold gate of the quality monitoring from buying link, brush carrier causes sparking also very general, the unreasonable meeting of design of brush carrier causes carbon brush jam in brush carrier, spring pressure is less is carbon brush can be caused to be in operation beat, spring pressure is excessive can be caused again carbon brush to contact tension with slip ring and generate heat serious.
Summary of the invention
The purpose of this utility model is: for improving Generator Slip Ring and carbon brush running environment, at utmost avoid Generator Slip Ring generation spark phenomenon.
The utility model content is:
A kind of plug type generating set brush carrier, comprise handle, baffle plate, terminal block, carbon brush, brush carrier conduction rack, brush box, described handle is fixed on baffle plate by fixed screw, described carbon brush is connected with terminal block, be fixedly connected with between described brush box with brush carrier conduction rack, also comprise constant force spring, described carbon brush is fixed in the notch of brush box by constant force spring.
Described brush box rear portion is welded with a connecting piece, and described brush box is fixedly connected with described brush carrier conduction rack by described brace.
The mode that described brush box and described brush carrier conduction rack are fixedly connected with is that bolt is connected.
Described brace is spill.
Notch on described brush box is of a size of 18mm × 44mm.
Described constant force spring pressure is 1.2N-1.6N.
Described constant force spring pressure is 1.35N-1.45N.
The radius of curvature of described constant force spring is 10mm.
The dielectric strength of described constant force spring is 0M Ω.
Accompanying drawing explanation

Fig. 2 is brush carrier dress carbon brush front schematic view;
Fig. 3 is the schematic diagram at the brush carrier back side;
Fig. 4 is the vertical view (being contained on generator) of brush carrier;
Wherein, 1 handle, 2 baffle plates, 3 fixed screws, 4 terminal blocks, 5 constant force springs, 6 notches, 7 brush boxs, 8 wiring noses, 9 carbon brush brush pigtails, 10 carbon brush, 11 pads, 12 bolts, 13 brush carrier conduction racks, 14 braces, 15 generator brush holders.
Embodiment
Illustrate with embodiment below in conjunction with accompanying drawing.
Plug type generating set brush carrier, for generating set, generator both positive and negative polarity brush holder respectively has 16 brush carriers, and every pole brush carrier divides 8 rows around slip ring circumference, and often arrange 2, each brush carrier can fill 4 carbon brush;
With reference to Fig. 1-Fig. 3, brush carrier comprises handle 1, baffle plate 2, terminal block 4, carbon brush 10, brush carrier conduction rack 13, brush box 7, brace 14, the brush holder of brush carrier from generator can be taken off by handle 1 by engineer easily, handle 1 is fixed on baffle plate 2 by fixed screw 3, baffle plate 2 can prevent the slippage when operating handle 1 from touching the charged positions such as carbon brush, carbon brush 10 is connected with terminal block 4 by the wiring nose 8 of carbon brush brush pigtail 9 end, can ensure that carbon brush 10 and terminal block 4 have good electrical contact so that electric current is delivered to carbon brush 10 from brush carrier conduction rack 13 through terminal block 4 like this, carbon brush 10 contacts with the slip ring of generator, carbon brush model is the root NCC634 that rubs, specification is 25 × 32 × 100, carbon brush 10 upper end contacts with constant force spring 5, carbon brush 10 lower end is stuck in the notch 6 of brush box 7, notch 6 is of a size of 18mm × 44mm, and stretch out brush box and be about about 2cm, fix with bolt 12 and pad 11 between brush box 7 and brush carrier conduction rack 13,
With reference to Fig. 4, brace 14 is welded on brush box 7 back side, brace 14 is spill, brush box 7 is fixedly connected with brush carrier conduction rack 13 by brace 14, carbon brush 10 can be ensured like this in brush carrier in same plane, and then ensure that four carbon brush 10 in a brush carrier are stressed identical, can effectively reduce wear;
Brush carrier conduction rack 13 and generator brush holder contact area reach 90%, and conductive capability improves greatly, too increases the stability of brush carrier on brush holder simultaneously; Constant force spring 5 grade of steel is SUS301, radius of curvature: 10mm, and size: 0.29mm × 12mm × 270mm is thick × wide × long, and dielectric strength: 0M Ω, spring pressure is 1.35N-1.45N.
