Motor cooling ventilation controlled valve and motor cooling ventilation automatic control method

Abstract

The invention provides a motor cooling ventilation controlled valve. The motor cooling ventilation controlled valve is arranged in redundant space of a motor cooling ventilation pipeline and comprises a mounting plate and an electromagnetic valve, wherein the mounting plate is fixed in redundant space; the electromagnetic valve is arranged on the mounting plate; the top of the electromagnetic valve is pushed against a ventilation inlet of the redundant space; the electromagnetic valve comprises an electromagnet, a valve, an elastic compression member and a contact-type inductive switch; the elastic compression member is arranged between the electromagnet and the valve; the contact-type inductive switch is arranged on the upper surface of the electromagnet and is connected to a motor control system through monitoring circuits; the elastic compression member is arranged along a vertical direction so as to push the valve against the ventilation inlet of the redundant space; the electromagnet is provided with an armature column which can be pulled by the electromagnet to move downwards; the armature column extends out from the electromagnet; and the top of the armature column is fixedly connected to the valve. The motor cooling ventilation controlled valve has the beneficial effects that the motor cooling ventilation controlled valve realizes the automatic starting and stopping of the motor cooling ventilation pipeline and the real time monitoring of a valve operation state and improves the maintenance efficiency of motor ordinary operation. The invention also provides a motor cooling ventilation automatic control method.

Description

technical field [0001] The present invention relates to a ventilation and cooling system of a wind power generator, and mainly relates to a motor cooling and ventilation controllable valve, which is used to control the opening and closing of the cooling vent of a motor installed in a high-altitude wind turbine nacelle in the form of a wheel tower. The present invention also relates to An automatic control method for motor cooling and ventilation. Background technique [0002] The motor installed in the high-altitude wind turbine nacelle in the form of a wheel tower needs to discharge hot air to reduce the temperature of the motor during operation, and has the effect of ventilation and cooling. Design ventilation ducts in the motor ventilation and cooling system to discharge hot air to reduce the operating temperature of the motor. In areas with good operating climate, such as inland and plains, the ventilation ducts in the motor ventilation and cooling system can be desig...
