Abstract
Belong to a kind of neon sign electron transformer high voltage package manufacturing process.The mixture that adopts 821-III epoxy resin and curing agent is as filling agent, and to put into vacuum degree be that the vacuum tank of 750mm mercury carries out deaeration in 15 fens and handles, and afterwards it poured in the coil and the space between shell of preheating, is advisable to flood coil.And then whole device is put into above-mentioned vacuum tank for the 2nd time carry out deaeration in 15 fens processing once more.Last successively under three kinds of temperature of 80 ℃, 100 ℃, 120 ℃ respectively the oven dry through 3 hours, 1 hour, 3 hours handle.The high voltage package that adopts this technology to make is high pressure resistant, and long service life.
Description
The invention belongs to a kind of rainbow electronic lamp transformer high-voltage and pack fabrication technique.
Existing neon sign electron transformer high voltage package process for making is: twines more than 40 layers at the enamelled wire with φ 0.07mm-φ 0.1mm on the end tube, and every layer 40～60 circle, and lay the thin fat of polyester of a bed thickness δ=0.06mm, about 500 Ω of its internal resistance at interlayer.The coil that will twine is put into shell then, and preheating 2 hours under 80 ℃ of temperature.General 6101 epoxy resin and the ethylenediamine mixture of adopting is as filling agent, and its weight ratio is 100: 30.Above-mentioned intermixture is poured among the coil and the space between the shell of preheating, and spontaneous curing at room temperature.
Above-mentioned Process is owing to adopt 6101 epoxy resin and ethylenediamine mixture as filling agent, its dielectric strength is low, particularly under the room temperature situation, be cured, thereby can not thoroughly remove the interior bubble of high voltage package, cause the compressive resistance of whole device poor, its the highest can only be withstand voltage 10,000 volts, generally have only about 30 hours useful life continuously.
The objective of the invention is to provide a kind of improved neon sign electron transformer high voltage package manufacturing process,, improve dielectric strength, thereby improve the compressive resistance and the continuous useful life of whole device to remove the bubble in the high voltage package.
For achieving the above object, the neon sign electron transformer high voltage package manufacturing process of the present invention's employing is as follows:
The mixture that adopts 821-III epoxy resin and curing agent is as filling agent, and its weight ratio is 100: 28.Put it into vacuum degree then and be and keep carrying out in 15 minutes deaeration in the vacuum tank of mercury of 750mm and handle.Pour into through in the coil and the space between the shell of preheating through this filling agent that deaeration is handled, the groundwater increment of filling agent directly is φ 0.12～φ 0.16mm with the submergence coil enamelled wire that the present invention adopts of being advisable.Interlayer is placed thick δ=0.04mm mylar, and its internal resistance is 200 Ω.Afterwards, whole device is put into vacuum degree still handle for the vacuum tank of 750mm mercury carries out the vacuum defoamation second time, the time still is 15 minutes.After vacuum defoamation is for the second time handled, supplementary irrigation full irrigation injecting once more.Dry processing at last.This oven dry is handled and is divided into three phases.Phase I dried 3～3.5 hours under 80 ℃～85 ℃ temperature; Second stage was 100 ℃～105 ℃ oven dry 1～1.5 hour; Phase III was 120 ℃～125 ℃ oven dry 3～3.5 hours.Make its natural cooling then.
The present invention adopts twice vacuum defoamation to handle, bubble in filling agent and the whole high voltage package is deviate from, and employing 821-III epoxy resin is as the filling agent of main component, its dielectric strength height, handle through the oven dry of three phases, can bring into play the high insulation resistance of 821-III epoxy resin more fully.
The high voltage package that adopts Process of the present invention to make, its dielectric strength height, long service life is through test, high pressure resistantly when adopting the rainbow electronic lamp no-load transformer of this high voltage package assembling reach 30,000 volts, and use continuously after the loading and do not find punch-through more than 150 hours yet.
Embodiment: the enamelled wire with φ 0.14mm twines 40 layers on end tube, every layer 50 circle, totally 2000 circles.Interlayer is added with the mylar of a bed thickness δ 0.04mm, and its internal resistance is 200 Ω.Make the coil that twines 80 ℃ of preheatings 2 hours.
The mixture that adopts epoxy resin and curing agent is as filling agent, and its weight ratio is 100: 28.It is after the vacuum tank of 750mm mercury keeps 15 minutes, it to be poured in the coil and the space between the shell of preheating that this filling agent is put into vacuum degree again, and groundwater increment is advisable to flood coil.They being put into for the second time vacuum degree again and be the vacuum defoamation that the vacuum tank of 750mm mercury carried out 15 minutes handles.Dry processing afterwards, divide three phases to dry, the phase I is under 80 ℃ of temperature, continuous drying 3 hours, and second stage is to dry 1 hour in the time of 100 ℃, the phase III then in the time of 120 ℃, dried 3 hours.Make its natural cooling then.
