Problems solved by technology

[0004] At present, the brake cylinders of the braking system of wind turbines are all connected in series. When one of the cylinders is damaged, it is impossible to judge which cylinder is leaking, and it cannot be monitored by the automatic control system of the wind turbine to quickly judge the fault. Points cause difficulties, so its safety and reliability are not good; the structure is also more complicated, and the braking operation of the locking cylinder is all done manually, which is inconvenient to operate; there are only one or two types of braking pressure provided. It cannot meet the different requirements of wind turbines for braking force under different working conditions

Abstract

The invention relates to an integration hydraulic brake system of a wind generating set, comprising a main bearing brake cylinder, a yaw brake cylinder, a locking cylinder and an integration brake device, and all parts are mutually connected by pipelines provided with a stop valve, a manual exchange valve and a magnetic exchange valve with the function of manual operation, wherein a pressure switch I for alarming is arranged at an oil leaking port of the brake cylinder. The hydraulic brake system has the advantages of manual operation function, compact volume, simple structure and simple operation.

Description

technical field [0001] The invention relates to a hydraulic braking system, in particular to an integrated hydraulic braking system of a wind power generating set. Background technique [0002] The braking system of the wind turbine includes three parts: the main shaft brake, the yaw brake and the locking brake of the locking cylinder, which is an important part of the wind turbine. [0003] Wind turbines have high requirements on the safety and reliability of the braking system: not only can they be reliably braked when the power grid is working normally, but they must also It has the ability of reliable braking, and the structure should be simple. In addition, under different working conditions, the braking force required by the wind turbine is different. [0004] At present, the brake cylinders of the braking system of wind turbines are all connected in series. When one of the cylinders is damaged, it is impossible to judge which cylinder is leaking, and it cannot be mo...
