Description

Electric brush device with heating function

Technical Field

The utility model relates to a generator equipment technical field, concretely relates to from brush device of taking heating.

Background

To work in plateau or moist environment under the motor, the indoor moist environment of sliding ring can be to great influence the steady operation of motor, and current motor is laid the heating wire or set up special heater near the one end inner wall of sliding ring brush yoke usually in the generator housing, adopt these two kinds of modes to heat the dehumidification and heat the indoor air of sliding ring earlier, rethread thermal conduction heating brush box, this kind of heating mode not only consumes the power than higher, has increaseed the complexity of generator design moreover.

SUMMERY OF THE UTILITY MODEL

To the not enough of prior art existence, the utility model aims to provide a from brush device of taking heating.

In order to achieve the above object, the utility model provides a following technical scheme:

the electric brush device with the heating function is characterized by comprising a brush holder, wherein a wire collecting box and a plurality of brush boxes are arranged on the brush holder, a plurality of carbon brushes are arranged in the brush boxes, and resistance wires are wound on the brush boxes.

Preferably, a wire groove for accommodating the resistance wire is spirally arranged on the outer side of the brush box along the height direction.

Preferably, the two sides of the brush boxes are provided with fixing lugs, lug holes are formed in the fixing lugs, mounting holes corresponding to the lug holes are formed in the brush frame, and the lug holes are connected with the mounting holes through bolts and nuts.

Preferably, the resistance wire is sleeved with an insulating tube, and the insulating tube is an insulating tube with a heat resistance grade of F.

Preferably, the lead wires of the resistance wires are uniformly led into the wire collecting box.

Compared with the prior art, the utility model discloses a set up the heating wire on the brush box, can reduce the distance of heating device with the carbon brush, both improved heating efficiency, reduce the loss to the electric energy, also make the dehydrating unit's of generator design complexity greatly reduced.
