Description
Technical field
Tin dress is warded off the present invention relates to electric process equipment field, more particularly to a kind of gear lifting copper bar bus line joint
Put.
Background technology
In the overhaul of the equipments, transformation, installation process of power transformation specialty, it is often necessary to carry out conducting copper joint making.
In the work, there is together very crucial process to need to complete：Copper bar joint wards off tin.The meaning for warding off tin is：Copper bar joint wards off tin
It can effectively prevent copper busbar from overlapping oxidation and the galvanic corrosion on surface afterwards, it is to avoid contact resistance increases.Taken on copper busbar joint
The requirement connect, in National Standard of the People's Republic of China《Electric device installing engineering bus device is constructed and acceptance specification》（State
Mark GB/ 50149-2010）In have a clear stipulaties, the 3.1.8 articles regulation of national standard GB/ 50149-2010：
1. the faying surface through silver-plated process can be directly connected to；2. bronze medal and copper：Outdoor, high temperature and the moist or gas that is corrosive to bus
The interior of body, it is necessary to ward off tin, can be directly connected in dry interior；3. the faying surface of aluminium and aluminium can be directly connected to；4. steel and steel
Faying surface must not be directly connected to, should ward off tin or it is zinc-plated after connect；5. bronze medal and aluminium：In dry interior, copper conductor should ward off tin, room
Outer or relative air humidity is close to 100% interior, and through using copper to aluminum adapter bar, copper end should ward off tin；6. bronze medal faying surface should ward off tin,
Steel faying surface should use galvanizing；7. steel faying surface should use galvanizing；8. the fixed face of metal-enclosed bus bolt should be plated
Silver.
In hydroelectric generation enterprise, ambient humidity is higher.The in the 3.1.8 articles of national standard GB/ 50149-2010 regulation
2nd, the 5th and the 6th article, the electrical connection copper bar joint of hydroelectric generation enterprise must ward off tin.
At present in the prior art, unspecial copper bar joint tinning device makees owner to the tin of warding off of copper bar joint
To pass through pure artificial operation：By electric welder, by the block tin in tin pot, uniformly barbecue is to melting, by copper bar joint manually is spread into weldering
In tin cream insertion high temperature tin liquor, the personnel for holding copper bar are taken to take out copper bar after the several seconds, another hand-held cleaning wiping cloth of personnel is rapid to warding off
Tin face is wiped, and must will be warded off tin face as far as possible as early as possible and be wiped to smooth, special messenger's monitoring must be had by entirely warding off tin process.This work is extremely
It is few to be completed by four people：Electric welder, hold copper bar personnel, wipe joint personnel and full-time guardian.Conventional method has following two
The problem of individual aspect：
1）Timeliness problem
1. ward off tin face treatment effect unstable, often to repeat to ward off tin or make leveling processing, inefficiency with fitter process（With complete
Into exemplified by one group of three copper bar joint, 35 minutes~50 minutes are about needed；2. personnel are superfluous more（The people of operating personnel three, sole duty monitoring
One people）, can cause to be short of hands.
2）Safety problem
The tin fine grinding of high temperature, which is splashed, when 1. operating easily scalds human body；2. oxy arc melts tin formation localized hyperthermia, naked light high-temperature mobile
Easy human body of burning.The safety problem that tin face is warded off with conventional process is protruded.
Therefore, need badly and develop a kind of device for efficiently and safely to copper bar bus line joint ward off tin.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides a kind of gear lifting copper bar bus line joint tinning device.
The tinning device of the present invention can be realized semi-automatically to be carried out warding off tin operation to copper bar bus line joint, and operating efficiency is high, wards off tin effect
Really good, security is good, and low manufacture cost, beneficial to popularization.
The present invention concrete technical scheme be：A kind of gear lifting copper bar bus line joint tinning device, including it is base, molten

Comparative example 1
Tradition wards off tin method：By electric welder, by the block tin in tin pot, uniformly barbecue is to melting, by copper bar joint manually is spread into weldering
In tin cream insertion high temperature tin liquor, the personnel for holding copper bar are taken to take out copper bar after the several seconds, another hand-held cleaning wiping cloth of personnel is rapid to warding off
Tin face is wiped, and will be warded off tin face as far as possible as early as possible and be wiped to smooth, entirely warding off tin process has special messenger's monitoring.
The contrast of embodiment and comparative example
（1）Personnel contrast：Copper bar is carried out using conventional method and wards off tin, and in addition to full-time guardian, operating personnel at least need three
People：Electric welder, hold copper bar personnel, wipe joint personnel.And copper bar tinning device is used, in addition to full-time guardian, it is only necessary to
One people can just complete whole operations.
（2）Contrast on effect：Copper bar is carried out using conventional method and wards off tin, and it is unstable that copper wards off tin face treatment effect, often to enter
Row repeats to ward off tin or is carried out warding off the leveling processing of tin face, inefficiency with file.And copper bar tinning device is used, copper bar wards off Xi Mianchu
The disposable success of reason, without phenomenon of doing over again.Due to having used the fine and smooth resistant to elevated temperatures sheep of hair matter in 1 and 2 particularly in embodiment
Felt wiper rail, it is more bright and clean more smooth than conventional process that copper bar wards off the processing of tin face.Every copper bar of conventional process needs
40 minutes, using can be foreshortened to after copper bar tinning device 21 minutes.
（3）Safe effect is contrasted：After tinning device, during the molten tin of heating, electric tin stove is placed on operating desk wiping
Wipe in the dedicated slot under frame, stablize firm.The whole heating process flames of anger, all the time by arch between operating personnel and electric tin stove
Wiping stand is isolated, the risk that no person is scalded.When operating tinning device, copper bar is whether installed or solder(ing) paste is smeared, operated
Personnel are always by wiping stand gear outside electric tin stove；During warding off tin and wiping, personnel also keep enough with tin stove always
Safe distance.
