The utility model is applied to the field of slip ring chambers of wind turbines.
Description
Technical Field
The utility model relates to an auxiliary device based on a slip ring chamber heater of a wind turbine generator.
Background
The slip ring chamber heater is a common heating device and is used for reducing moisture in the slip ring chamber and reducing the pitting corrosion of the slip ring caused by the fact that carbon powder is attached to the slip ring due to overlarge moisture;
the existing technology is to add a heater at the bottom of the slip ring chamber to remove moisture in the slip ring chamber, but the method has obvious disadvantages, carbon powder generated by the operation of the components is attached to the exposed heating pipe of the slip ring chamber, so that the carbon powder burns, the ignition is caused, and the fire hazard is caused.
Disclosure of Invention
The utility model aims to provide an auxiliary device based on a slip ring chamber heater of a wind turbine generator.
The above object is achieved by the following technical scheme:
an auxiliary device based on wind turbine generator slip ring chamber heater, its constitution includes: the heater body is arranged at the bottom of a slip ring chamber of the wind turbine generator, a protective shell is arranged above the heater, the whole protective shell is a semi-closed rectangular box body, and a heat dissipation hole is formed in the top of the protective shell;
the side face of the protective shell is provided with a round hole, a power wire of the heater body penetrates through the round hole, and a wire sheath is sleeved in the round hole.
Auxiliary device based on wind turbine generator system sliding ring room heater, the bottom parallel of protective housing be fixed with two mounting brackets, the mounting bracket passes through the bolt assembly and fixes the protective housing in the bottom of wind turbine generator system sliding ring room.
The auxiliary device based on the wind turbine generator slip ring chamber heater is characterized in that the radiating hole is of a rectangular protruding box structure, and one side of the radiating hole is of an open structure.
The utility model has the beneficial effects that:
1. the utility model solves the problem that carbon powder generated in the slip ring chamber is easy to adhere to the heater to cause combustion in the running process of the carbon brush in the slip ring chamber, so that the slip ring chamber of the fan fires. The direct contact of carbon powder with the heater body is avoided, so that the stability of equipment is improved, and the fan faults are indirectly reduced.
2. The utility model improves the sparking phenomenon of carbon powder in a slip ring chamber caused by a heater, reduces fire accidents caused by the firing of the slip ring chamber, and provides an auxiliary device for the slip ring chamber heater of a wind turbine.
3. The utility model can effectively prevent the carbon powder in the slip ring chamber from being in direct contact with the heating rod, reduce the combustibility and reduce the fire accident of the wind turbine generator caused by the slip ring chamber.
