Abstract
A heating device of a high-voltage box type motor is a heater or a heating band which is fixed on pressing rings at two ends of a stator iron core in a surrounding way, and is fixed by a fixing clip in the circumferential direction. For the heating device, the structure is simple, the function is practical, the needed power is low, the power consumption is less, the heating of an iron core and a coil is sufficient, the heating is uniform, the heating device is not directly contacted with the coil, damage to insulation is avoided, the fixing is simple and convenient, and the replacement and the maintenance are convenient.
Description
Technical field
The utility model relates to the heater of the box motor of a kind of high pressure.
Background technology
When relative air humidity bigger, when motor is stopped using, starting heater can make stator winding place space temperature slightly higher than ambient temperature, so just be not easy to produce condensed water, winding is moisture-sensitive not, and turn-to-turn capacitive (leakage) electric current can be very little, and winding insulation intensity can not reduce, it is aging to slow down insulating material, improves the useful life of motor.
The design of motor heater at present is varied, and what have is installed in bottom of shell, changes inconvenience; What have is installed on the base inner side plate or support end plate inwall or end cap inwall, easily localized hyperthermia; What have is installed on the muscle that has axial gusset, and installation is changed more inconvenient; What have is placed on heater on the casing separately, is fixed in the motor side plate outside, so not only increases motor weight, and cost is also high.Above in addition all structure heater common drawback are: for making 5 ℃ of the projecting ambient temperatures of casing internal temperature, required power is big, and power consumption is bigger.
The utility model content
The utility model purpose is to provide the heater of the box motor of a kind of high pressure, and power demand is little, and little power consumption is fixing simple and convenient, changes easy to maintenance.
To achieve these goals, the utility model adopts following technical scheme: the heater of the box motor of a kind of high pressure, heater are heater or heating tape, and heater is around on the trim ring that is fixed on the stator core two ends.
Described heater is around on the trim ring that is fixed on the stator core two ends, and fixes by geometrical clamp in a circumferential direction.
The utility model is simple in structure, function is practical, and power demand is little, and little power consumption, iron core and coil are heated fully, homogeneous heating, and directly do not contact with coil, avoid injuring insulation, fixing simple and convenient, change easy to maintenance.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Embodiment
Embodiment: as shown in Figure 1 and Figure 2, the heater of the box motor of a kind of high pressure, heater 2 is heater or heating tape, heater 2 is around being fixed in the stator core 1.Heater 2 is around on the trim ring that is fixed on stator core 1 two ends, and it is fixing to pass through geometrical clamp 3 in a circumferential direction.
In the bigger area of air humidity, when motor is stopped transport, open motor space heater, the air of stator winding region is heated, prevent from that there was dampness in the air to cause dielectric strength to reduce.The heater power demand is little, and little power consumption, iron core and coil are heated fully, homogeneous heating, and directly do not contact with coil, avoid injuring insulation, fixing simple and convenient, change easy to maintenance.
Claims (2)
1. the heater of the box motor of high pressure, it is characterized in that: heater is heater or heating tape, heater is around being fixed on the stator core trim ring.
2. the heater of the box motor of high pressure according to claim 1 is characterized in that: described heater is around on the trim ring that is fixed on the stator core two ends, and fixes by geometrical clamp in a circumferential direction.
