Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
With reference to Fig. 1, details are as follows for the concrete technology of dosing technology of the present invention.
Step (1), by clean clean for the installed surface of high-pressure discharge light source and trigger, installed surface applies one deck 703 silicon rubber, places and treat 703 silicon rubber solidifications under natural environment.The material used when carrying out clean to the installed surface of light source is preferably absolute ethyl alcohol, and its cleaning effect is good, use safety.703 silicon rubber are that a kind of cementability is good, high strength, and free from corrosion single-component room-temperature-vulsilicone silicone rubber, has excellent electrical insulation capability, sealing property and ageing-resistant performance, can in the scope of-50 DEG C-+250 DEG C Long-Time Service.703 silicon rubber solidification processs be one from surface solidification process internally, within 24 hours, (room temperature and 55% relative humidity) is by the degree of depth of solidification 2 ~ 4mm, if site location is darker, especially the position touching air is being not easy, the completely crued time will extend, if temperature is lower, curing time also will extend.Consider that 703 coated silicon rubber only need thin layer, therefore only need place under natural environment during step (1) solidification and be not less than 4h.
Step (2), puts into baking oven by the high-pressure discharge light source being coated with 703 silicon rubber, takes out after toasting 2h ± 0.5h under 70 DEG C ± 10 DEG C conditions.This step can guarantee that 703 silicon rubber cling on light source surface.
Step (3), is placed on high-pressure discharge light source by encapsulating die, cement with the outer contacting face position of pressure sensitive adhesive tape at encapsulating die and high-pressure discharge light source.Step (4), is placed on trigger in encapsulating die, and welded with the extraction electrode silk scolding tin of high-pressure discharge light source by the output line of trigger, pad place applies 703 silicon rubber, places and treat 703 silicon rubber solidifications under natural environment.Same step (1), 703 silicon rubber are placed and are not less than 4h and solidify to make it under natural environment.After step (3) and (4) complete, light source and trigger complete Primary Location in encapsulating die.
Step (5), puts into baking oven by high-pressure discharge light source, trigger and encapsulating die, takes out after toasting 2h ± 0.5h under 70 DEG C ± 10 DEG C conditions.This step guarantees that 703 silicon rubber at pad place can reliably cement.
Step (6), gets appropriate casting glue and stirs, and puts into vacuum defoamation machine and carries out degasification deaeration, inclined heated plate 30min ± 5min.This step is the stand-by phase of casting glue, and when implementing this step, need to operate according to required casting glue amount, when required amount is larger, this step needs repetition 3-5 time, to reach enough use amounts.In addition, consider to meet that high pressure is fire-retardant, sealing, resistant to elevated temperatures requirement, preferably adopt southern famous model to be the casting glue of ND-313.
Step (7), the casting glue of deaeration is poured in encapsulating die, inner space is all filled up, place under natural environment and treat that casting glue solidifies, time needed for solidification is not less than 48h, and during practical operation, the time of casting glue solidification is subject to the impact of natural environment humidity, humidity is larger, and casting glue is faster for curing time.
Step (8), removes encapsulating die, is removed by the casting glue of high-pressure discharge light source excess surface, and surface wipes is clean, completes embedding work.
Technique of the present invention solves High-Voltage Insulation, installs fastness and thermal characteristics problem, ensure that product reliably working.
