Problems solved by technology

[0004] The main purpose of the delayed start of the system is to make the electrical components in the control box available within the allowable temperature range. The thermal conductivity is slow, and it needs to be delayed for a period of time to start normally; when the ambient temperature meets the starting conditions, the system does not need to be delayed for 60 minutes before running, so the existing technology wastes a lot of time and greatly affects the efficiency of power generation

Abstract

The invention provides a start device of a low-temperature type paddle change control system. Through the skillful connection of a temperature sensor, a time relay and a relay contactor, when environmental temperature is low and a heater heats to ensure that temperature is raised to confirm to a system start condition, and after a period of time delay, the system can be normally started; and whenthe environmental temperature conforms to the start condition, the system is directly operated without delaying time for 60 minutes. The device saves a large quantity of generating time and greatly improves the generating efficiency.

Description

technical field [0001] The invention relates to a starting device of a low-temperature pitch control system, which belongs to the technical field of wind power. Background technique [0002] At present, in the pitch control system, it is mainly divided into two types according to the temperature type: one is the normal temperature pitch control system; the other is the low temperature pitch control system. [0003] Such as figure 1 As shown, the low-temperature pitch control system will monitor the ambient temperature in real time when the system is running, that is, the system includes a temperature sensor T. When the temperature meets the starting conditions, that is, the ambient temperature is greater than 5 degrees, the time relay T1 delays 60 Minutes later, the relay K3 is energized and the system runs. When the temperature sensor T detects that the ambient temperature is less than 5 degrees, the relay K4 is energized, and the heater is heated. When the temperature is...
