Description

Sand dust abrasion test device and the test method of train motor insulation structure

Technical field

The present invention relates to sand dust abrasion test device and the test method of a kind of test unit and test method of motor product, particularly a kind of train motor insulation structure, be mainly used in the sand dust abrasion test of train motor insulation structure.

Background technology

Train motor is in operational process, because high speed wind action has the built-in system that a lot of sand dusts enters into motor, the very high speed of acquisition under the rotarily driving of rotor, and then insulation system is caused to shock, make the lost of life of insulation system, reliability reduces, and affects motor reliability of operation.Therefore general train motor all will carry out the anti-sand dust abrasion test of insulation system when dispatching from the factory.

Domestic sand dust abrasion test is all used conventional sand spray machine sand spray mostly at present, and traditional sand-blasting machine is single structure, can not realize sand amount, the multiple variablees such as sand speed regulate simultaneously, therefore test the Abrasion properties of resistance to sand dust that the result of gained can not general performance train insulation system in operational process, therefore test the Abrasion properties of resistance to sand dust that the result of gained can not general performance train insulation system in operational process, and present sand blast test is all to recycle with sand, especially the processing of dust is not easy to handle, need to carry out separately reinstalling in sand-blasting machine and using after collection and treatment, so waste very large, troublesome poeration, therefore need to be improved the anti-sand dust abrasion test of existing insulation system.

By the domestic Searches of Patent Literature, do not find the online Patents detecting of relevant spark plug withstand voltage properties, just find that there is the patent about the online context of detection of spark plug, mainly contain following:

1, the patent No. is CN201220006297.9, and denomination of invention is the utility model patent of " a kind of dust test chamber ", and this patent discloses a kind of dust test chamber, and it comprises: test casing; Be arranged at the funnel of below in this test casing; Be arranged at the floating dust blower fan in funnel; Be arranged at the stirring blower fan of below, funnel bottom; One end is communicated with funnel bottom, the sweep-up pipe that the other end is communicated with test casing top; Be communicated with sweep-up pipe and the sand dust of funnel bottom be blown into the drifting dust blower fan of top in test casing by sweep-up pipe; The division board that test casing is divided into operating room and circular chamber, the top of operating room and circular chamber is connected, and the below of operating room and circular chamber is connected; Be arranged at the circulating fan of circular chamber.

2, the patent No. is CN201010276671.2, denomination of invention is the utility model patent of " a kind of dust test chamber ", this patent discloses a kind of dust test chamber, and front is provided with able to turn on or off chamber door, and observation window is set on chamber door, chamber bottom arranges universal caster wheel, in casing, be provided with operating room, dust-blowing device and electric device, operating room is located at the rear portion of chamber door, and dust-blowing device is located at the bottom of operating room, be connected through flexible pipe with operating room, electric device is located at the right side of operating room.

Although above-mentioned two patents relate to dust testing device, but carefully analyze, can find out that these two patents are all the dust and sand effects for the little finding of sandblast amount, test for locomotive engine insulation system parts is certainly not all right, mainly how to process a large amount of dust, its sand can be recycled conveniently, still need and will further be improved.
