Abstract
The utility model discloses a kind of wind turbine power generation machine slip ring room internal rotor cable protection structures; insulating sheath is coated on the band iron adjacent with rotor cable in slip ring room; position on rotor cable apart from carbon brush brush holder side connector 34cm and apart from rotor junction box side connector 24cm respectively coats an insulating sheath, and rotor cable is fixed on slip ring room inner support by double button bands.Rotor cable disclosed in the utility model protects structure, and rotor cable is fixed on slip ring room inner support by double button bands, directly makes not contact between rotor cable and adjacent band iron.Insulating sheath further is coated on band iron and rotor cable again, accordingly even when double button bands damage, rotor cable contacts with adjacent band iron, also there is insulating sheath to be separated by between the two, the two directly contact is avoided, reduces the friction to rotor cable insulating layer, prevents its destruction from splitting.
Description
Technical field
The utility model relates to rotor cables to protect field, sliding more particularly to a kind of wind turbine power generation machine in the field
Ring casing internal rotor cable protection structure.
Background technique
There are the shakings of certain amplitude in high-speed cruising for wind turbine power generation machine, if its slip ring room in connection carbon brush brush holder and
Exist between the rotor cable of rotor junction box and adjacent band iron and contact, will lead to the insulating layer of rotor cable because long with band iron
Phase rubs and destroys, splits, and the conductive copper wire inside rotor cable will be connected with band iron, make three-phase in blower tower bottom rotor cabinet
50A fuse frequently fuses, and causes individual event ground fault and frequency converter failure.
Utility model content
Technical problem to be solved in the utility model, being just to provide one kind can be straight to avoid rotor cable and adjacent band iron
The wind turbine power generation machine slip ring room internal rotor cable protection structure of contact.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution:
A kind of wind turbine power generation machine slip ring room internal rotor cable protection structure, thes improvement is that: in slip ring room and turning
Insulating sheath is coated on the adjacent band iron of sub- cable, is connect on rotor cable apart from carbon brush brush holder side connector 34cm and apart from rotor
The position of wire box side connector 24cm respectively coats an insulating sheath, and rotor cable is fixed in slip ring room by double button bands
On bracket.
Further, being coated on insulating sheath on rotor cable is 10KV pressure resistance heat-shrink tube, respectively with 34cm and
Centered on 24cm point, two sides respectively extend 10cm to the left and right.
The beneficial effects of the utility model are:
Rotor cable disclosed in the utility model protects structure, and rotor cable is fixed on slip ring room by double button bands
On inner support, directly make not contact between rotor cable and adjacent band iron.It is further coated on band iron and rotor cable again exhausted
Edge sheath, accordingly even when double button bands damage, rotor cable contacts with adjacent band iron, also there is insulating sheath between the two
It is separated by, avoids the two directly contact, reduce the friction to rotor cable insulating layer, prevent its destruction from splitting, to be effectively reduced
Fan frequency converter system failure rate and spare parts consumption amount, protection generator amature winding safety, improve frequency convertor system pusher side
IGBT working efficiency improves wind turbine power generation amount.
Being coated on insulating sheath on rotor cable is 10KV pressure resistance heat-shrink tube, is respectively with 34cm and 24cm point
The heart, two sides respectively extend 10cm to the left and right, not only ensure that the bending radius of rotor cable, but also save heat-shrink tube dosage, are suitble to
It is promoted and applied when protection structure being installed to existing wind turbine power generation machine slip ring room internal rotor cable.
Detailed description of the invention
Fig. 1 is the signal of wind turbine power generation machine slip ring room internal rotor cable protection structure disclosed in the utility model embodiment 1
Figure.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment 1, as shown in Figure 1, present embodiment discloses a kind of wind turbine power generation machine slip ring room internal rotor cable protection knots
Structure coats insulating sheath 11, apart from carbon brush brush holder on rotor cable 2 in slip ring room on the band iron 1 adjacent with rotor cable
Side connector 34cm and position apart from rotor junction box side connector 24cm respectively coat an insulating sheath 22, and rotor cable is led to
Double button bands 33 are crossed to be fixed on slip ring room inner support 3.
In the present embodiment, the insulating sheath being coated on rotor cable is that 10KV pressure resistance heat-shrink tube (can be tight after heating
It is close to be coated on rotor cable), respectively centered on 34cm and 24cm point, two sides respectively extend 10cm to the left and right.
Rotor cable disclosed in the present embodiment protects structure, and rotor cable is fixed in slip ring room by double button bands
On bracket, directly make not contact between rotor cable and adjacent band iron.Insulation is further coated on band iron and rotor cable again
Sheath, accordingly even when double button bands damage, rotor cable contacts with adjacent band iron, also there is insulating sheath phase between the two
Every both avoiding directly contact, reduce the friction to rotor cable insulating layer, prevent its destruction from splitting.
