Abstract

The invention relates to a high-heat-dissipation-performance copper bar fixing structure. The structure comprises an installation pedestal, copper bars and insulation rack plates. Front and back sides of the installation pedestal are correspondingly provided with the insulation rack plates. The copper bars are horizontally penetrated into the installed on the insulation rack plates. The structure is characterized in that the insulation rack plates of the front and back sides of the installation pedestal and the copper bars are fixedly installed through L-shaped connection sheets. The design of the structure is scientifically and reasonably, the structure is compact, copper bar stability and connection reliability are increased, heat dissipation performance is good and assembling is convenient.

Description

technical field

[0001] The invention relates to a copper bar fixing structure, in particular to a copper bar fixing structure with high heat dissipation performance. Background technique

[0002] The frequency converter is an essential and important component in the wind turbine. The frequency converter excites the rotor of the doubly-fed asynchronous wind power generator, so that the amplitude, frequency and phase of the output voltage of the stator side of the doubly-fed generator are the same as those of the grid, and independent decoupling control of active power and reactive power can be performed as required . The inverter controls the doubly-fed asynchronous wind generator to achieve soft grid connection, reducing the adverse impact of the grid connection impact current on the motor and the grid.

[0003] The existing inverter is composed of main circuit system, power distribution system and control system. Including stator grid-connected switch, rectifier module, ...

Embodiment Construction

[0026] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0027] A copper bar fixing structure with high heat dissipation performance, including an installation base 1, a copper bar 2 and an insulating frame plate 3, the insulating frame plates are installed on the front and rear sides of the installation base correspondingly, and the copper bars are installed horizontally on the insulating frame plate. The innovation of the invention lies in: the L-shaped connecting piece 4 is used for fixed installation between the insulating frame plate and the copper bar on the front and rear sides of the installation base, so as to prevent the horizontal displacement of the copper bar due to the vibration of the equipment operation, Improve copper bar stability and connection reliability.
