Description
Technical field
The utility model belongs to high ferro locomotive line construction technique field, and in particular to high ferro locomotive switchgear is brilliant with polymerization
Silicon insulator.
Background technology
China's high ferro distance travelled ranks first in the world, and " four vertical four is horizontal " high iron skeleton is built up substantially, with high-speed railway
Fast development increasingly increases high ferro locomotive switchgear insulator demand, and EMU safe and reliable operation is car operation
The emphasis of maintenance.Existing high ferro locomotive switchgear is with insulator mostly using silicon rubber compound insulator, and the insulator is by upper and lower gold
Belong to flange, glass fibre plug, silicon rubber umbrella to form.Compare porcelain and glass insulator, silicon rubber insulator is in electric property
Aspect has very big upper raising.But after long-play, it has been found that some problems that silicon rubber insulator occurs：(1) plug
It is bad with the sealing performance at silicon rubber interface, plug is made easily to be corroded by sewage or acidic materials, long-play can cause plug
Brittle failure；(2) foggy weather, switchgear silicon rubber insulator are condensed in high-speed cruising, lower flange surface and full skirt in winter

Orchid, plug, upper flange and lower flange are integrated after press-connection machine crimping, and upper flange and lower flange use stainless steel material system
Into.
The insulator umbrella is coated on plug, and insulator umbrella includes multiple insulation of spaced set from top to bottom
Sub- umbrella, the diameter of the lowermost insulator umbrella are more than remaining insulator umbrella, have convex annular on the bottom surface of bottom insulator umbrella
It rises, annular protrusion is integrally formed with the insulator umbrella, and protrusion is axially looked up along plug and is located at lower flange periphery.
Polymerize crystal silicon material ontology have high mechanical strength, water absorbing capacity is low, volume resistivity is high, ageing resistance is good,
Anti-pollution dodges ability and waits excellent performances by force, and material is rigid nature, so full skirt can be done greatly.It is made absolutely with polymerization crystal silicon material
Edge increases creepage distance, and either electric property or mechanical performance is both greater than similar composite insulator.
The diameter of insulator umbrella the lowermost insulator umbrella is more than remaining insulator umbrella, during high ferro locomotive high-speed cruising,
When rainwater on insulator is dropped onto on the insulator umbrella of bottom, due to having on the bottom surface of bottom insulator umbrella and lower end
Gamp increases an annular convex platform, and the marginal dimension of annular protrusion is more than the marginal dimension of lower flange, then rainwater finally slides
It on to annular protrusion and forms water droplet and drips, will not drip on lower flange, protect lower end flanges from pollution and corrosion function；Together
When, by increasing the size of bottom insulator umbrella and setting annular protrusion, increase the creepage distance of insulator, improve its thunder
Surge voltage and Power Flashover Voltage prevent insulator umbrella from tear phenomenon occurs, and lower end flanges is protected to protect it from dirt
Dirty things influence causes to corrode discharge breakdown, and the front insulator that this is is incomparable, will not generate corona phenomenon, protect locomotive
Safe operation.
Herein described high ferro locomotive switchgear is as follows with the production process of polymerization crystal silicon insulator：First press-connection machine is set
Good parameter, then packs into upper flange by plug, and upper flange and plug are tightly crimped together under suitable pressure, then with setting
Parameter has been put to continue to crimp lower flange, such plug, upper flange and lower flange become one structure, compression joint type structure be it is current most
Advanced form, compared to embedded and integral structure, mechanical performance more stablize, be more uniformly stressed.
After the completion of crimping, plug, upper flange and lower flange are placed on together in the mold for making switchgear insulator,
Then heat up mold, and polymerization crystal silicon raw material are warming up to molten condition, and inject in mold at high temperature, then by one section when
Between heat preservation, cooling after, be formed by polymerization crystal silicon insulator umbrella be coated on plug, ultimately form high ferro locomotive switchgear use
It polymerize crystal silicon insulator.Molten condition is presented in polymerization crystal silicon material in the case of a high temperature, will be poly- after plug temperature is raised to centainly
Synthetic silicon materials moment is injected into die cavity, and polymerization crystal silicon material is closely coated on around epoxy resin plug, makes its sealing more
Add securely.Compared to composite insulator brushing coupling agent, this technique is more advanced, and coupling agent brushing unevenness is avoided to cause, and there are boundaries
Bread covers insecure.The electric property of insulator is enhanced, while because its leakproofness is good, dunghill will not be allowed to enter in product
Portion enhances plug corrosion resistance.
