Abstract
The invention relates to an insulating structure for a rotor coil for a high-voltage wound rotor motor. Copper coils are arranged in a rotor core; glass powder mica platinum, a polyimide thin film tape and a polyimide film polyaryl amide fiber paper composite material layer are coated on each copper coil; a slot wedge is formed on the polyimide film polyaryl amide fiber paper composite material layer; an epoxy novolac glass cloth plate is arranged between two copper coils; the glass powder mica platinum is coated on a linear segment of each copper coil; improved insulating varnish is coated on an inner surface of the glass powder mica platinum; the polyimide thin film tape is coated on the glass powder mica platinum; and an outer surface of the glass powder mica platinum and an outer surface of the polyimide thin film tape are arranged in parallel. The insulating structure for the rotor coil for the high-voltage wound rotor motor has the advantages of uniform insulating thickness of the linear segment of the rotor coil, smooth surface, convenient penetration of the rotor coil in the rotor core, and capacities of reducing groove shape area, saving the usage of effective materials, reducing manufacturing labor hour and guaranteeing safe and reliable operation of the motor.
Description
Technical field
The present invention relates to a kind of insulation system of high-tension winding rotor electric machine rotor coil, specifically be mainly used in the insulation system of high pressure three-phase wound-rotor asynchronous motor rotor coil.
Background technology
At present, the high-tension winding rotor electric machine mainly detent torques such as application and cement industry, mine hoisting require the big double place that requires Fraquent start.But it is that series resistor is convenient, the slip ring number is minimum and can produce good electric property, so such rotor winding all is connected into three-phase and all adopts two layer winding that the high-tension winding rotor electric machine all adopts formed coil and rotor winding.Because winding not necessarily belongs to same phase in the same groove, must insulation between two-layer winding.
Because of rotor when the normal operation, has very big centrifugal force, rotor generally all is designed to the semi-closed port flute profile, the structures shape of this kind flute profile coil can only wrap insulation afterwards from an end of rotor through the other end.It is smooth inadequately that the wrapped way of fillet mica tape half lap that adopts coil causes coil to wrap insulation back coil surface, brings very big trouble for the interspersed of coil, and in order to make coil can pass rotor core smoothly, the rotor slot shape size must be amplified.So cause motor when operation, to be subjected to produce after the effect of rotor centrifugal force and magnetic pull loosening easily, cause the accident easily.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of and both can guarantee insulating requirements, and need not to amplify the flute profile size, can pass the insulation system that rotor slot shape is guaranteed the high-tension winding rotor electric machine rotor coil that long-time running is safe and reliable again smoothly.
According to technical scheme provided by the invention, the insulation system of described high-tension winding rotor electric machine rotor coil, comprise polyamides film aromatic polyamide paper composite layer, the polyimide film band, glass dust mica platinum, the glass dust mica tape, copper coil, epoxy phenol aldehyde glass cloth laminated board, modification insulating varnish, rotor core and slot wedge, copper coil is installed in the rotor core, on each copper coil, all be coated with glass dust mica platinum, polyimide film band and polyamides film aromatic polyamide paper composite layer, on polyamides film aromatic polyamide paper composite layer, be provided with slot wedge, be provided with epoxy phenol aldehyde glass cloth laminated board between two copper coils, straightway at each copper coil is coated with glass dust mica platinum, inner surface at glass dust mica platinum is coated with modification insulating varnish, is covered with the polyimide film band in the external packets of glass dust mica platinum; The outer surface of described glass dust mica tape is concordant setting with the outer surface of polyimide film band.
This utility model makes rotor coil straight line portion insulation thickness even, and smooth surface is convenient to intert, rotor coil interting in rotor core reduced the flute profile area, saved effective material usage, when having reduced worker, motor long-term safety, operation have reliably been guaranteed.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is the vertical view of coil among the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, the present invention mainly is made of parts such as polyamides film aromatic polyamide paper composite layer 1, polyimide film band 2, glass dust mica platinum 3, glass dust mica tape 4, copper coil 5, epoxy phenol aldehyde glass cloth laminated board 6, modification insulating varnish 7, rotor core 8 and slot wedges 9.
The insulation system of this high-tension winding rotor electric machine rotor coil, comprise polyamides film aromatic polyamide paper composite layer 1, polyimide film band 2, glass dust mica platinum 3, glass dust mica tape 4, copper coil 5, epoxy phenol aldehyde glass cloth laminated board 6, modification insulating varnish 7, rotor core 8 and slot wedge 9, copper coil 5 is installed in the rotor core 8, on each copper coil 5, all be coated with glass dust mica platinum 3, polyimide film band 2 and polyamides film aromatic polyamide paper composite layer 1, on polyamides film aromatic polyamide paper composite layer 1, be provided with slot wedge 9, be provided with epoxy phenol aldehyde glass cloth laminated board 6 between two copper coils 5, straightway at each copper coil 5 is coated with glass dust mica platinum 3, inner surface at glass dust mica platinum 3 is coated with modification insulating varnish 7, is covered with polyimide film band 2 in the external packets of glass dust mica platinum 3; The outer surface of described glass dust mica tape 4 is concordant setting with the outer surface of polyimide film band 2.
Rotor liner polyamides film aromatic polyamide paper composite material 1, the straight line portion wraparound glass dust mica platinum 3 of copper coil 5, modification insulating varnish 7 is coated in glass dust mica platinum 3 inner surfaces uniformly before the wraparound, behind the wraparound again at the wrapped one deck polyimide film of the straight line portion outside half lap band 2 of copper coil 5.The bending section of copper coil 5 makes the outer surface of glass dust mica tape 4 concordant with the outer surface of polyimide film band 2 with the wrapped glass dust mica tape 4 of belting machine.
The present invention is convenient to copper coil 5 interting in rotor core 8 because the straight line portion insulation thickness of copper coil 5 is even, and smooth surface makes the flute profile width of rotor core 8 to reduce relatively, has reduced the flute profile area, has saved effective material usage of slot wedge 9.The present invention has simplified manufacture craft not changing structural material, can not reducing effective material cost again when increasing insulation costs.
