Description
Technical field
The present invention relates to a kind of composite insulator, more particularly, to a kind of electric railway is combined with rod pillar porcelain polymer
Insulator and preparation method thereof.
Background technology
Composite insulator is compared porcelain insulator because of it at aspects such as weight, resistance to pollution flashover voltages and is had an enormous advantage and be subject to
To the favor of industry, especially this feature of pollution flashover voltage height.Research discovery, the umbrella skirt construction of composite insulator and pollution flashover voltage
Between there is certain relation so that other conditions are identical but its pollution flashover voltage of composite insulator that umbrella skirt construction is different is different.
The impact to composite insulator Flashover Characteristics for the umbrella footpath is as follows：Umbrella footpath increases, then the equivalent diameter of composite insulator increases
Greatly, there is negative influence to Flashover Characteristics although the creep age distance of composite insulator accordingly increases, can improve to a certain extent
Pollution flashover voltage, but the limitation improving, instead result in the utilization rate relative reduction of creep age distance, and excessive umbrella footpath meeting
Consume excessive material, there is no economic benefit；Umbrella footpath is too small, can lead to the deficiency of leakage distance, therefore select the head in umbrella footpath
Principle is wanted to be to select the umbrella footpath with economic benefit on the premise of whole insulator of guarantee meets leakage distance.
The impact to composite insulator Flashover Characteristics for the umbrella spacing is as follows：Umbrella spacing increases, and can improve compound inslation first
The contamination accumulation characteristics of son；Secondly, bridge joint between umbrella be can effectively suppress, serious icing snowberg and the concatenation of retardance electric arc prevented；
3rd, the utilization rate of creep age distance can be lifted；But the premise increasing is to ensure that whole composite insulator has climbing of abundance
Electrical distance.Umbrella spacing reduces, and can improve the creep age distance of composite insulator in the case that insulation height is certain, but dirty
The lightning pressure not linear increase with the increase of creep age distance, umbrella spacing is too small, is susceptible to bridge, the profit of creep age distance between umbrella
Use rate relative reduction.
Existing composite insulator, internal substantially all employing glass fiber reinforcement epoxy rod, because its weatherability poor it is impossible to
It is exposed in atmospheric environment and runs, according to incompletely statistics, domestic electrical phylogenetic insulator Fragile Split has reached many simultaneously
Rise, brittle failure is frequently experienced in the high-pressure side of composite insulator field intensity concentration, occur the composite insulator of Fragile Split typically all to deposit
In the situation that sheath, end seal are damaged.It is generally acknowledged that：The probability very little that brittle failure occurs is it is impossible to prevention, it is impossible to detection, is docked
That touches net is very harmful.
Electrification railway contact net composite insulator runs geographic range extensively, and different regions have its geographical particularity,
Thus causing operating condition complicated, there is extraneous uncertain factor in transport, I＆M process in composite insulator simultaneously, from
And affect the safe operation of composite insulator.

First time cure stage preferably adopts low temperature gel process, so can reduce internal stress produced by solidification process volume contraction.By
Relatively slow in first time solidification, the material of contraction can supplement in time, and bubble can be discharged in time, can reduce the formation of inner void.Different
At a temperature of injection or castable gelation time as shown in table 2 with hardening time.
| Temperature | Gelation time | Molding time |
| 130℃ | 30～40min | 40～50min |
| 140℃ | 15～20min | 25～30min |
| 150℃ | 12～15min | 15～20min |
| 160℃ | 8～10min | 12～15min |

Electric railway rod pillar porcelain polymer composite insulator of the present invention is stretched out to umbrella, big umbellule umbrella
The reasonable set of the ratio that the difference stretched out and umbrella spacing are stretched out with umbrella, reaches the optimal effect of composite high voltage insulator Flashover Characteristics
Really.
By the present invention in that using hydrophobicity cycloaliphatic epoxy resin, improve electric railway rod pillar porcelain polymer
The ability that the anti-blown sand ability of composite insulator, external force resistance destroy, can prevent the destruction to product for the unfirmly closing.Engineering staff simultaneously
Can trample on full skirt within the specific limits if necessary in work progress, thus facilitating construction, improve engineering staff and applying
Safety coefficient during work.
To illustrate the enforcement of the method for the present invention below by specific embodiment.It is presented herein below for preparation as shown in Figure 3
Polymer insulation part, concrete grammar includes：
(1) select corresponding construction mould, be installed on production to be processed on process equipment.This mould is according to following structural requirement
Corresponding manufacture：The top rade of full skirt is 6 °～16 °, and angle of declination is 0 °；Arrange between the big umbrella shape projection of each two equal diameters
One little umbrella shape is raised；The difference that the umbrella that big umbrella shape is raised and little umbrella shape is raised stretches out is 18mm；The wherein raised umbrella of umbrella shape stretches out
For 55mm；
(2) porcelain core rod is inserted in the centre bore of gold utensil, is then integrated by adhesive mucilage binding, obtain porcelain core rod-
Gold utensil complex；The porcelain core rod surface of porcelain core rod-gold utensil complex is using the commercially available coupling agent Kai Muluo through dehydrated alcohol dilution
Grams 608 carry out pretreatment；Pretreatment porcelain core rod-gold utensil complex is put into the relevant position in mould；
(3) outdoor type hydrophobicity cycloaliphatic epoxy resin is expelled in mould using automatic pressure injection molding technique,
Charging bore is 16mm, and feed time is 5min, and feed pressure is about 0.4MPa.Carry out in a mold solidifying for the first time, solidification
Temperature is 130 DEG C, and gel time is 35min, and molding time is 45min；
(4) demoulding is then placed in electrocaloric effect carrying out second solidification, and hardening time is 10 hours, and solidification temperature is
110 DEG C, obtain electric railway as shown in Figure 3 rod pillar porcelain polymer composite insulator.
In sum, the resistance to pollution flashover of the present invention, anti-unfirmly closing, anti-blown sand, can obtain the optimal effect of Flashover Characteristics.Rod pillar
The polymer umbrella cover of porcelain polymer composite insulator has excellent hydrophobicity, migration of hydrophobicity and electrical resistance with HCEP material
Can, there is higher mechanical strength simultaneously.The present invention has the same of excellent hydrophobicity, migration of hydrophobicity and electric property
When, also there is anti-blown sand ability, the ability of external force resistance destruction, the destruction to composite insulator umbrella cover for the unfirmly closing can be prevented, and
Have within the specific limits can assist to climb and step on performance, facilitate the construction of engineering staff, improve the safety system in work progress
Number.Electric railway of the present invention adopts the porcelain porcelain core with porcelain full skirt with the porcelain core rod of rod pillar porcelain polymer composite insulator
Rod, porcelain porcelain core rod high mechanical strength, weather resistance is strong, because of extraneous corrosion, and brittle failure will not occur, so that the present invention is combined absolutely
Edge can prevent Fragile Split in use.Thus meeting electric railway and Highspeed Catenary
Use demand.
By specific embodiment, the present invention has been done above further describe it should be understood that, here specifically
Description, should not be construed as the restriction to the spirit and scope of the invention, and one of ordinary skilled in the art is reading this explanation
The various modifications after book, above-described embodiment made, broadly fall into the scope that the present invention is protected.
