Abstract
The invention relates to a mica insulator which comprises an insulator body; the insulator body comprises two metal pieces, i.e. a female metal insert (1) which is provided with internal thread or an outer bolt turned from hexagonal stainless steel and a cutting groove, and a male metal insert (2), and a certain gap is arranged between the two metal inserts; a mica glass insulation layer (3) which comprises mica powder and glass powder is inlaid between the two metal inserts; a coating (4) which comprises organic silicon is applied on the outer surface of the insulator body; and the invention has the advantages that the tight, firm and reliable insulated combination of the metal inserts and the mica glass can meet the special technical requirements of a rail transit vehicle on the mica insulator; and the mica insulator has excellent high-temperature resistance, mechanical strength, electrical performance and weather resistant performance.
Description
Technical field
The present invention relates to a kind of mica insulator, relate in particular to the structure of this mica insulator.
Background technology
Insulator is the most popular base components of mesohigh electrical power trans mission/distribution system, is used for live part is insulated and supports.High voltage power transmission and transforming circuit toughened glass insulator is arranged, and outer solid-core post porcelain insulator adopts the epoxy spike pulling support, the various materials of polymer composite insulator of silicon rubber full skirt external insulation or the like, and different shape has thousands of kinds and specification.
The China of reform and opening-up, the fast development of Chinese city track traffic industry has been achieved in the surge of urban population, and existing in the market insulator can not satisfy the requirement of field of track traffic special technique.The used insulator of rail traffic vehicles will have high-temperature stability, excellent mechanical strength (be stretching resistance, resistance to bending, compressive resistance, moment of torsion all require very high), excellent electric property (being that flashover voltage, puncture voltage, proof voltage, electric capacity, insulation resistance all have higher requirement) and the weather resistance of excellence etc.
At the mica insulator development initial stage, because structural design is unreasonable, selection is improper, technology is incomplete, powder, loose, metal insert blackout, stretching resistance do not increase, electric breakdown strength is not high to cause the mica insulation sub-surface to fall.Can't produce in batches, not satisfy the requirement of track traffic industry.
Summary of the invention:
The technical issues that need to address of the present invention provide a kind of mica insulator, are intended to solve the above problems.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: body; Described body comprises: be made up of through car system internal thread or outer bolt and by female metal insert and two metalworks of male metal insert of cutting groove hexagonal stainless steel, between two metal inserts certain interval arranged; A glass bonded mica insulating barrier of being made up of mica powder, glass dust is embedded between two metal inserts; A coating of being made up of organosilicon is coated on the outer surface of body.
Compared with prior art, the invention has the beneficial effects as follows: since metal insert and glass bonded mica insulated combination quite closely, firmly, reliable, can satisfy the special technical requirement of rail traffic vehicles to mica insulator: mica insulator is high temperature resistant, mechanical strength, electric property and weather resisteant can be excellent.
Description of drawings
Fig. 1 is a structure chart of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
As seen from Figure 1: the present invention includes: body; Described body comprises: be made up of through car system internal thread or outer bolt and by female metal insert 1 and 2 two metalworks of male metal insert of cutting groove hexagonal stainless steel, between two metal inserts certain interval arranged; A glass bonded mica insulating barrier 3 of being made up of mica powder, glass dust is embedded between two metal inserts; A coating 4 of being made up of organosilicon is coated on the outer surface of body;
The shape of described female metal insert 1 and male metal insert 2 is: two for full internal thread or be two full outer bolts or be an internal thread, other end outer bolt.
The present invention is shaped through mould heat pressure by the insulation of the about parcel of metal insert (1,2) glass bonded mica, handles the back appearance and is coated with anti-pollution flashover organosilicon.Diagram mica insulator overall dimension varies (being different size), and shape also can change to some extent.With outside type of attachment inserts two full internal threads (as Fig. 1), two full outer bolts, an internal thread, an outer bolt are arranged.Produce by customer requirements, but the basic structure of mica insulator is constant.
400 ℃ of mica insulator long-term work temperature of the present invention, 500 ℃ of softening temperatures.Press Fig. 1 physical dimension 50mm * ∮ 50mm * 2M10 mica insulator, concrete according to as follows through the test of mechanical industry electrical material product quality supervision inspection center:
1, flashover voltage 33KV
2, puncture voltage 41KV
3, proof voltage passes through 50Hz.22KV.1min
4, insulation resistance 1000V 1.17 * 10
7M Ω
5, electric capacity 1KHz 18PF
6, stretching resistance 23.5KN
7, end bending resistance 4.8KN
8, compressive resistance 89.3KN
9, torsional moment＞0.050KNm.
