The analysis of the causes of transformer oil leakage reasons - environmental temperature change

Refer to instruction for use of current 8500w gasoline generator transformer,transformer running environment temperature 40 ℃,the highest temperature is + minimum temperature of 40 ℃. Our factory area this summer outdoor certainly higher than 40 ℃,the highest temperature field measurement of motor run capacitor the surface temperature is close to 50 ℃. After each part of the summer heat equipment thermal expansion,due electricalmotor1.blogspot.com to environment temperature drop after high temperature season,but all motor vehicle kinds of material shrinkage is not consistent with the temperature,cause the leakage of oil from the surface. This point in our plant is particularly prominent.

Three-phase asynchronous motor winding fault analysis and processing

Winding short circuit Due to poor welding or use corrosive flux,have not cleared after welding,it may cause a pot of welding or loose;Subjected to mechanical stress or collision coil short circuit,also can make the wire burned,short circuit and earth fault in a couple of wire and burn a single or a few wire short circuit,several other wire due to the increase of current temperature rise,cause heating

winding and open circuit.Generally fall into one phase winding end disconnection,turn-to-turn short circuit,parallel branch circuit,wire and burn more of a single circuit,rotor broken cage.1.The fault phenomenon Motor can't start,three phase current balance,no abnormal noise or vibration,temperature rise more than permitted or smoke.2.The reason (1) during overhaul and maintenance touch off or manufacturing quality problems.,(2) winding each element (phase) group and the winding and fixture wire connection head welding,sealing off long running overheating.(3) by the mechanical force and electromagnetic force make winding damage or pulled apart or cause drag mark.(4) or interphase short circuit and grounding caused winding coils badly burned or fuse,etc.Methods to examine 

3.(1) the method of observation.Breakpoint most occurred in winding ends,look have without touch fold,joint the presence of desoldering.(2) a multimeter.Using resistance,to "Y" type of connection to connect a table bar in the center of the "Y" shape,the other in turn in the head end of the three-phase

winding,infinite phase has a breakpoint;"Delta" connection type of short connection,measuring winding in each group respectively,infinity to breaking point.www.dongfeng-motor.com (3) test lamp.Method with former,such as bright a photograph for open circuit.(4) megohmmeter.Resistance tends to infinity (that is,not as a zero value) is the cut-off point.(5) current meter method.Motor at runtime,use current meter to measure three phase current,if the imbalance of three phase current and short-circuit phenomenon,and no is a phase winding is part of the current small short circuit fault.(6) bridge method.A phase when the motor is bigger than the other two phase resistance,resistance show that the phase winding part of open circuit fault;

(7) ac geared motor the current balance method.For "Y" type of connection,but after the three-phase winding parallel,alternating current into the low voltage large current,if the current in the

three-phase winding is greater than 10%,one end of the small current for the circuit;For "delta"

connection type,the stator winding of a contact apart first,then by interlinked into low voltage high

current,one of the small current for open circuit.ac motor wind generator (8) broken cage detector

test.Check,if the broken rotor cage millivoltmeter readings should be reduced.4.Open circuit

processing method (1) the opening in the end,the connection after welded,the package on insulation

materials,set on the insulation tube,good binding,dry again.(2) the winding due to interturn,interphase short circuit and grounding,etc and cause severe charred generally should change new windings.(3) to the breaking point in the slot,belong to a few breakpoints for emergency treatment,the grouping elimination method is adopted to find the breakpoint,and broken in winding connection and the insulation used after 220v ac electric motors qualified.(4) can be used for broken squirrel-cage rotor cage welding,cold connection or change the original repair.

Maintenance skills

Motor running or failure,can see,hear,smell,touch four methods to prevent and troubleshooting in

time,guarantee the safe operation of motor.A,see Observe the motor running process with and without

exception,the main performance for the following situation.1.The stator winding short circuit,may see

the motor smoke.2.The serious overload or short of motor phase operation,speed will slow down and

have a heavy "buzzing" sound.3.The motor run normally,but suddenly stops,will see the wiring loose

sparks;A portion of the blown fuse or stuck.4.If the motor vibration,could be gearing jammed or motor

fixed,loose bottom bolt,etc.5.If the motor inside contact point and forms a discoloration,burn mark

and stain,then there may be local overheating,electric vehicle motor poor contact or winding conductor joint burned,etc.Second,listen to the Motor should be a uniform and normal operation of the lighter

"buzzing" sound,no noise and special voice.If the noise is too big,including electromagnetic

noise,bearing noise, Ventilation noise,mechanical friction sound,all may be failure precursor or

failure phenomenon.For electromagnetic noise,if the motor send out the voice of high and low and

heavy,the reason may have the following kinds.(1) the uneven air gap between stator and rotor,the

voice of high and low and high and low time interval constant,this is so that the stator and rotor bearing wear and tear caused by a heart.(2) three phase current balance.This is by three-phase winding grounding,short circuit or poor contact,if sound is very depressing,explain motor serious overload or short shipment Line.(3) the iron core is loose.Due to vibration in the operation of the motor in the core fixed bolt looseness caused by loose core silicon steel sheet,making noises.2.The bearing noise,should often listen in the motor running.Monitoring method is: will the screwdriver end to resist bearing installation site,the other end,close to the ear can hear To the bearing running

noise.If the bearing is working well,its sound is continuous and tiny "rustling" sound,does not have

the change of high and low,and metal.If appear the following Several kinds of voice is not normal.

(1) bearing operation "creak" sound,this is metal,generally for bearing caused by lack of oil,should be apart bearing charging right amount of grease.(2) if there "pumping mile",this was the voice of the ball rotates,generally for dry or lack of oil,grease can be loaded with a moderate amount of

grease.(3) if there "raise price" or "creak" sound,for the bearing inner ball irregular movement of

sound,this is the inside of the bearing ball or motor long-term need not,embellish Grease caused by

the drought.3.If the drive mechanism and transmission mechanism continuous instead of high and low sounds,processing can be divided into the following kinds of situation.(1) periodic "snapped" sound for belt joint is not smooth.(2) periodic "drumming sound for loose coupling,or between the pulley and shaft and key or keyways wear cause.(3) uneven clash,as the wind leaf fan cover cause

collision.Three,smell By the smell of the smell of motor diagnosis,and can also prevent failure.If

found to have special smell of paint,the internal temperature of the motor is too high;If found to

have heavy the smell of burnt food or coke Smell,may motor fan be insulation breakdown or winding has been burned.Four,touch Touch the temperature of the motor areas can also determine the cause of the problem.In order to ensure safety,application in hand over hand to touch an electric shock around

motivation shell,bearing parts,if found Temperature anomaly,the reason might be the following.1.Poor

ventilation.Such as fan,air duct jam,etc.2.The overload.Cause excessive current and the stator

winding overheating.3.The stator winding interturn short circuit or three phase current balance.4.The

frequent start or braking.Around 5.electricalmotor1.blogspot.com If the bearing temperature is too high,it may be caused by bearing damaged or short of oil.
