Abstract
The invention discloses a six-cabinet control system for variable-pitch wind-driven power generation, which comprises three shaft control cabinets. The three shaft control cabinets are connected in a form of a ring. PLC (Programmable Logic Controller) modules, lightning protection modules and backup power supply chargers are integrated in the shaft control cabinets. The shaft control cabinets are respectively connected with a battery cabinet and a motor. In the invention, connecting wires are reduced, the six-cabinet control system is largely optimized in mounting and connecting aspects, and is easy to operate. The hub internal space is saved by reducing cabinet number, so the operation space of operators in latter maintenance and repair is enlarged. As the cabinet interior is further integrated and simplified, the match among the modules is more stable, and maintenance and repair time is also largely shortened.
Description
Technical field
The invention belongs to wind generating variable-propeller control field, relate in particular to a kind of six cabinet control system.
Background technique
At present, in becoming oar control field, control system is divided into that the control cabinet as depicted in figs. 1 and 2, is respectively the mounting type of above-mentioned seven cabinet casings in wheel hub and the schematic representation of wire harness Placement in conjunction with control among three axle control cabinets and one.Seven cabinet casings comprise control cabinet 1, three axle control cabinet 2 and three battery racks 3 in one.In the middle control cabinet 1 the PLC module is installed, is connected three axle control cabinets 2 respectively, in the blower fan operation process, accurately control the angle of swing of blade.But in the practical application, axle control cabinet 2 connects and the communication input output with middle control cabinet 1, needs a large amount of connecting line and attachment plug, causes the connection point of contact too much, and the collecting time of signal is longer.Precision decreases on whole blade control system.The intensification degree of control system is lower simultaneously, and the stability of control limits to some extent.Under the situation of wind-powered electricity generation industry fast development, the cost of control blower fan and the limitation in the maintenance in later stage and space, six cabinet control system are subjected to more blower fan MANUFACTURER and welcome.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the objective of the invention is to propose a kind of variable-blade wind power generation with six cabinet control system.
Purpose of the present invention will be achieved by the following technical programs:
A kind of variable-blade wind power generation comprises three axle control cabinets with six cabinet control system, and annular connects between described three axle control cabinets, is integrated with the PLC module in the described axle control cabinet, and described axle control cabinet is connected with motor with battery rack respectively.
Further, the integrated lightning protection module that is provided with in the described axle control cabinet.
Further, the integrated back-up power charger that is provided with in the described axle control cabinet.
Six cabinet control system are being evaluated from mode of operation, have reduced connecting line, be convenient to complete set manufacturer and reduce the installation quantity of cabinet in cabinet is packed the wheel hub process into, thereby be improved on production capacity.Aspect the connection of cabinet, the number of connection of line reduces, and is convenient to cabling and is connected in actual mechanical process.So six cabinet control system install be connected aspect optimize greatly, be convenient to operation.
The minimizing of cabinet quantity also can reduce synchronously for the wheel hub volume inside, has saved the space, for also striving for bigger operating space for operator aspect the maintenance in later stage and the maintenance.
Because done more integrated and simplification in cabinet, the cooperation between module is more stable, the time in maintenance and maintenance process also shortens greatly.
Compared with prior art, beneficial effect of the present invention is:
(1) saves installing space, increased the operating space;
(2) save the installation time, improved manufacturing efficiency;
(3) reduced the whole cost of product;
(4) be convenient to the maintenance and the maintenance of product.
Following constipation closes embodiment's accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.
Description of drawings
Fig. 1 is the structural representations of prior art seven cabinet casings of the present invention in wheel hub;
Fig. 2 is the schematic representation of the wire harness Placement of prior art seven cabinet casings of the present invention;
Fig. 3 is the schematic representation of the wire harness Placement of the embodiment of the invention six cabinet casings.
Embodiment
The present invention has disclosed a kind of novel variable-blade wind power generation with six cabinet control system, as shown in Figure 3, comprise three axle control cabinets, different with prior art (as Fig. 2) is, control cabinet during the present invention is not provided with, annular connects between described three axle control cabinets, and no longer is that direct and middle control cabinet is connected, integrated PLC module, lightning protection module and back-up power chargers etc. in the control cabinet in former in the described axle control cabinet, described axle control cabinet also is connected with a motor with a battery rack respectively.Reduced connecting line after using the present invention, install be connected aspect optimize greatly, be convenient to operation; Because the minimizing of cabinet quantity also can reduce synchronously for the wheel hub volume inside, has saved the space, for also striving for bigger operating space aspect the maintenance in later stage and the maintenance for operator; Because done more integrated and simplification in cabinet, the cooperation between module is more stable, the time in maintenance and maintenance process also shortens greatly.
Claims (3)
1. a variable-blade wind power generation comprises three axle control cabinets with six cabinet control system, it is characterized in that: annular connects between described three axle control cabinets, the integrated PLC module that is provided with in the described axle control cabinet, and described axle control cabinet is connected with motor with battery rack respectively.
