Abstract
The invention discloses a process for manufacturing an insulated sleeve of a refrigeration high-voltage motor power terminal, which sequentially comprises the following steps of: coating silicone grease, namely coating a layer of silicone grease on a core rod; winding a mica tape, namely tightly winding the mica tape on the core rod coated with the silicone grease; roasting and setting, namely putting the core rod into a heating device, roasting and setting, cooling and disassembling the core rod to obtain the insulated sleeve; and trimming the sleeve, namely trimming the profile of the insulated sleeve by using a trimming tool. The invention solves the problems in the prior art and provides the process for manufacturing the insulated sleeve of the refrigeration high-voltage motor power terminal, wherein the insulated sleeve can reliably work in a refrigerant and refrigerating machine oil and has high insulation protection performance.
Description
Technical field
The manufacture craft of high-voltage motor power supply terminal insulating sleeve the present invention relates to freeze.
Background technology
High-voltage motor is meant rated voltage at the above motor of 1000V, and common for example 6000V and 10000V voltage are because external electrical network difference also has multiple voltage grades such as 3300V and 6600V.Because high-voltage motor power is directly proportional with the product of voltage and current, therefore when power increases to a certain degree (as 300KW/380V), the restriction that electric current is subjected to the permission ability to bear of lead just is difficult to do greatly, or cost is too high, need realize high-power output by improving voltage.The refrigerant compressor employed insulating material of high-voltage motor, owing to be operated in and be full of in gas, liquid cold-producing medium and the refrigerator oil, so insulating material must tolerate the erosion of these working medias, and the time of insulating material tolerance erosion has directly determined the life-span of refrigeration motor, so when making the refrigeration motor, require these insulating material can tolerate the erosion of these working medias.
Be electrically connected the position in the refrigeration motor and be the exposed copper conductor and the copper screw bolt of binding post, in order to guarantee the reliability of this part insulation, thereby designed insulating sleeve.If this current-carrying part exposes in cold-producing medium and refrigerator oil, the conductive material that they bring just might reduce the insulation property at this place and cause the electric fault of motor to produce, and increases an insulation protection part therefore must for this part.This kind protective materials just requires to be operated in reliably in the gas, liquid working media of cold-producing medium and refrigerator oil, and has a good insulation performance performance, can guarantee the insulation property at the exposed position of binding post conductive component, protective materials is also wanted to prevent that the conductive materials (conductive mechanical impurity etc.) of refrigerating system inside from touching the current-carrying part of high-voltage connection terminal certainly.
Summary of the invention
In order to overcome the deficiency that prior art exists, the object of the present invention is to provide can reliably working in cold-producing medium and refrigerator oil, refrigeration high-voltage motor power supply terminal insulating sleeve manufacture craft that the insulating protection performance is good.
For reaching above purpose, the invention provides a kind of refrigeration high-voltage motor power supply terminal insulating sleeve manufacture craft, it comprises the following steps of carrying out in order: the silicone grease smearing step applies one deck silicone grease on plug; The mica tape winding step is closely twined mica tape being coated with on the described plug of silicone grease; The baking fixating shape step is put into heater with described plug, and the baking typing is unloaded described plug after cooling and promptly made insulating sleeve; The reconditioning casing step uses dressing tool that described insulating sleeve is carried out contouring.
Further improvement of the present invention is that described mica tape is many glue mica tapes.
Further improvement of the present invention is that described dressing tool comprises file.
Further improvement of the present invention is that in described baking fixating shape step, heating-up temperature is 160 ℃, and be 8 hours heating time.
Further improvement of the present invention is that the heater that uses is hot-die in described baking fixating shape step.
The invention has the beneficial effects as follows:
1, can be operated in mix (freon and novel cold-producing medium are as R22, the R134a etc.) in the gas, liquid working media of cold-producing medium and refrigerator oil reliably;
2, reach of the requirement of the exposed parts of high-voltage connection terminal to insulation property;
3, prevent that the conductive materials (conductive mechanical impurity etc.) of refrigerating system inside from touching the current-carrying part of binding post.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
A kind of refrigeration high-voltage motor power supply terminal insulating sleeve manufacture craft, it comprises the following steps of carrying out in order:
A) silicone grease smearing step: on plug, apply very thin one deck silicone grease, silicone grease has good heat conduction, heatproof, insulation property, be heat-resisting device ideal medium material, and stable performance, in use can not produce etchant gas, can the metal that be contacted not exerted an influence, can help to eliminate the air gap of contact-making surface, increase type of thermal communication, reduce thermal resistance, reduce the working temperature of insulating sleeve, improve reliability and increase the service life.
B) mica tape winding step: closely twine mica tape on the plug of silicone grease being coated with.In the present embodiment, the mica tape that uses is many glue mica tapes, many glue mica tapes are made up of mica paper, glass cloth and binder resin, it is that many rubber mouldings press the insulation system main material to form, binder resin content is 38%, the binder resin performance has determined the insulation system performance, only is 8% to compare with binder resin content in the low resin mica tape, and many glue mica tapes have excellent insulation property.What need mention especially is, in order to guarantee insulation property, mica tape closely is wrapped on the plug of making frock by 1/2 lap wound method, because plug has the end shelves, the final thickness of mica tape preferably is higher than an end shelves 1mm to 2mm.
C) baking fixating shape step: plug is put into heater baking typing, and in the present embodiment, the heater that uses is the hot pressing film, and heating-up temperature is 160 ℃, and baking temperature is 8 hours; After treating hot pressing film cooling, plug unloaded promptly make insulating sleeve.
D) reconditioning casing step, clear up with instrument pair of wire connection terminals insulating sleeves such as files, unnecessary grease and mica tape are cleared up from the binding post insulating sleeve, avoid in use unnecessary grease and mica tape to drop in system cryogen and the refrigerator oil, influence the performance of cold-producing medium and refrigerator oil, also avoid unnecessary material to cause the obstruction of cold-producing medium and refrigerator oil circulating line.
By above-mentioned execution mode, be not difficult to find out the present invention be can reliably working in cold-producing medium and refrigerator oil, refrigeration high-voltage motor power supply terminal insulating sleeve manufacture craft that the insulating protection performance is good.Above execution mode only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the people that is familiar with this technology understand content of the present invention and is implemented; can not limit protection scope of the present invention with this, all equivalences that spirit is done according to the present invention change or modify all contains body in protection scope of the present invention.
