Description
Technical field
The present invention relates to motor fields, and in particular to a kind of arc protection motor.
Background technique
The carbon brush of motor and the carbon brush of generator are referred to as carbon brush for electric machine or motor brush again, and the appearance of carbon brush for electric machine is a little
As wiping the rubber item of pencil, there is conducting wire extraction on top, volume varies.And the Wound-rotor type carbon brush used on motor
It often will appear the such case that sparkles, initiation accident be easy when sparkling and burns motor, therefore, reduction carbon brush sparkles several
Very it is necessary to and be rate the reason of the Wound-rotor type carbon brush on motor can sparkle: we are using wound-rotor motor
When carbon brush, due to constantly wearing to carbon brush among long-term operation, it is in contact face injustice, the pressure of carbon brush
Power not enough either slip ring is non-round and bearing on there is oil droplet or other sundries to fall between slip ring and carbon brush etc. a variety of feelings
Condition can all cause carbon brush to give off sparks.How to eliminate the submethod that carbon brush sparkles: we can be used fine sandpaper by carbon brush and
The contact surface of slip ring is polished more smooth, or carries out adjustment appropriate to the pressure of carbon brush, and check whether slip ring is justified, if
If the incrustation for adhering to or being trapped in brush carrier is more, compressed air purging is cleared away or used using brush.Carry out slip ring and carbon brush
Safeguard procedures can effectively reduce Wound-rotor type and click the probability that carbon brush sparkles.
Summary of the invention

(93) on same vertical line；The sealing ring (95) is fixed on two extra shell (94) open-ended places, when No.1 shell (93)
Merge with two extra shells (94), sealing ring (95) is sealed, if generating electric arc between electrical contact will not disorderly splash；When motor is normal
Running, two elevating mechanisms (4) are stretched outward, and No.1 shell (93) is contacted with two extra shells (94) at this time, No.1 electrical contact
(91) it is contacted with No. two electrical contacts (92), forms access, motor starts turning, when motor temperature exception, two elevating mechanisms (4)
To central reduction, elevating lever (43), which drives No.1 shell (93) to move up, at this time separates it with two extra shells (94), motor
Power-off.
