Description

Wind power converter modular cabinet

technical field

The utility model relates to a matching device for wind power generation, in particular to a cabinet body of a converter.

Background technique

The existing wind power converter equipment usually connects the power device, the control part, the heat dissipation device, etc. with a fixing frame, a mounting plate and screws and the cabinet to form an integral structure that is not easy to be disassembled. Because the cabinet is not easy to disassemble, there are problems such as heavy equipment weight, large volume, poor versatility and interchangeability of the cabinet body, and inconvenient transportation, installation and maintenance.

For example, in a wind power generation site, the doors reserved for wind towers are generally relatively small, so the wind power converter cabinets need to be pre-installed into the wind tower when building the tower, which brings great inconvenience to the construction of the wind tower.

Contents of the invention

The utility model provides a modularized cabinet in order to solve the integral defect of the wind power converter cabinet.

In order to solve the above problems, the technical solution adopted by the utility model is: it includes more than one unit cabinet, and a power unit, a rectifier unit, a chopping unit, a capacitor filter unit, a reactor unit and a control unit are arranged in the unit cabinet;

The unit cabinet is a frame structure composed of columns and beams. Fixing holes with a spacing of 25 mm are set on the columns and beams. Guide rails are installed in the cabinet through the fixing holes. All unit cabinets are fixed side by side on the same base.

The power unit, the rectifier unit, and the chopper unit respectively adopt assembly boxes of the same size and structure, and the two sides of the assembly box are equipped with connection terminals, and the front of the assembly box is equipped with a control signal interface, which constitutes each unit module , each unit module is loaded into the unit cabinet through guide rails;

The capacitor filter unit, the reactor unit and the control unit are respectively assembled on the bracket of the unit cabinet in the form of a whole to form each unit module.

Each assembled unit module is connected to the connecting terminal of the corresponding unit module.

The positive effect of the utility model is: since the whole cabinet body can be disassembled, each functional module unit can be disassembled, and the loading of each module unit adopts a guide rail type, which is convenient for installation and disassembly. In the process of product transportation and installation, the product can be disassembled, and the smaller wind tower door can also facilitate access. At the same time, it is also convenient to quickly replace the unit module in a short time when it fails.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 3, the utility model is that four unit cabinets 1 are fixed side by side on the base 8. The unit cabinet structure is shown in Figure 1. It is a frame structure composed of columns and beams, and spacing is set on the columns and beams. 25mm fixing holes, guide rails are installed in the cabinet through the fixing holes.

The power unit, rectifier unit, and chopper unit respectively adopt the same assembly box 9 of 420mm×400mm×225mm. The structure of the assembly box 9 is shown in FIG. 11. The front of the assembly box 9 is equipped with a control signal interface 10, which constitutes a power unit module 3, a rectification unit module 2, and a chopping unit module 4; The form is assembled on the bracket of the unit cabinet to form the capacitor filter unit module 5, the reactor unit module 6 and the control unit module 7; the control unit module 7 is separately placed in the first unit cabinet through the guide rail, and the rectification unit module 2, The chopper unit module 4 and the capacitor filter unit module 5 are placed in the second unit cabinet, the power unit module 3 is separately placed in the third unit cabinet, and the reactor unit module 6 is placed in the fourth unit cabinet. Each assembled unit module is connected to the connecting terminal of the corresponding unit module.
