Abstract
The invention relates to a high-voltage motor built-in wind screen plate capable of introducing cooling wind to clearance between a rotor winding and a stator winding. The built-in wind screening plate comprises a molded wind screening sidewall. The molded wind screening sidewall is characterized in that the wind screening plate is cylindrical; the fixed end of the cylindrical wind screening sidewall is provided with 8 to 12 fixed mounting holes; the middle part of the inner side at the other end of the cylindrical wind screening sidewall is an annular guide wind channel cavity formed by the guide wall; the diameter of the an inner cavity of the annular guide wind channel cavity is larger than the outside diameter of an inner fan of the motor by 8 to 14 millimeters; and a wind screening end wall is integrally arranged between the wind screening sidewall and the guide wall. As the fixed end of the wind screening sidewall can be directly mounted on a motor stator rib, the cost is low; as the diameter of the inner cavity of the annular guide wind channel cavity is large, the wind screening plate does not need to be detached and is convenient to maintain when a rotor is detached; and as the wind screening plate and the inner fan form a closed loop, the motor has good cooling effect.
Description
Technical field
The present invention relates to a kind of cooling or ventilating system of motor, especially a kind of embedded wind deflector of high tension motor that cooling air all can be imported the gap between rotor and the stator winding.
Background technology
Motor heating when work can cause reduce useful life, and its heating position mainly is rotor and stator winding.So internal fan is housed on motor rotor shaft, the motor operation drives the internal fan rotation, and outside air is transported to motor internal, the rotor and the stator winding of motor is forced cooling, with the rotor of reduction motor and the temperature rise of stator winding.The internal fan that also has on the high-voltage motor armature spindle of box support during the internal fan rotation, drives air-flow from support side plate air inlet air intake, and from seat top plate or the air-out of back side panel air outlet, draft type is a radial ventilation, and motor is cooled off.Motor internal is equipped with deep bead, constitute gas flow loop with internal fan, this deep bead can all import cooling air in the gap between rotor and the stator winding, improves the utilance of cooling air, more effectively reduces the temperature rise that rotor and stator winding produce when work.At present, the high-voltage motor of big multi-tank support, the wooden partition of its deep bead (12) is all made horn-like, as shown in Figure 1.In order to make air-flow form closed loop, with the seat top plate sealing, respectively weld a fixed head (13) at the support two ends, deep bead (12) is fixed on the fixed head (13).The deep bead of this structure is the steel plate weldment, and overall dimension is wayward, often produces the phenomenon that deep bead and internal fan are wiped mutually; Support need weld two keep out the wind fixed head or the welding tube that keeps out the wind, and has increased cost; In addition, the deep bead internal diameter, need unload deep bead and rotor could be extracted out during the maintenance motor less than the internal fan external diameter, and maintenance is wasted time and energy.
Summary of the invention
Waywardly easily wipe mutually in order to overcome deep bead overall dimension in the prior art with internal fan, cost height, maintenance motor need unload deep bead and deficiency that the maintenance that causes is wasted time and energy, the invention provides a kind of embedded wind deflector of high tension motor, this embedded wind deflector of high tension motor is not only processed simply, cost is low, and motor dismounting, easy to maintenance, the motor good cooling results.
The technical scheme that technical solution problem of the present invention is adopted is: a kind of embedded wind deflector of high tension motor, the sidewall that keeps out the wind that comprises a moulding, it is characterized in that: the described sidewall that keeps out the wind is cylindric, on the stiff end of this cylindric sidewall that keeps out the wind, have 8-12 can with the joining fixed installation of motor stator muscle hole, in this cylindric middle part of keeping out the wind sidewall other end inboard is the chamber, a ring-type drainage air channel that is formed by the drainage wall, the intracavity diameter in this chamber, ring-type drainage air channel is greater than motor internal fan external diameter 8-14mm, described keep out the wind between sidewall and the drainage wall be one with the end wall that keeps out the wind of its one design.
Circular arc is connected between keep out the wind end wall and the sidewall that keeps out the wind of described and the sidewall that keeps out the wind, the design of drainage wall one, the drainage wall.
The present invention can adopt plastic material once molding formed, and size is accurate, and is in light weight.The stiff end of sidewall of keeping out the wind can be directly installed on the motor stator muscle, and support need not weld the deep bead fixed head, reduces cost.The intracavity diameter in chamber, ring-type drainage air channel need not be pulled down deep bead greater than motor internal fan external diameter during motor dismounting rotor, and is easy to maintenance.Deep bead and internal fan form loop, motor good cooling results.
The invention has the beneficial effects as follows that processing is simple, cost is low, and is aesthetic in appearance, and installation, maintenance is convenient, the motor good cooling results.
