Polymer Insulator Manufacturing Txheej txheem
Raw Material Inspection (Lub Fiberglass Qws)
Lub insulator tus tub ntxhais pas nrig yog ua los ntawm siab -kub resistant, corrosion{1}}resistant, los yog acid{2}} cov khoom resistant. Cov pas nrig tseem ceeb yuav tsum tau ua cov qauv ntsuas, suav nrog kev ntsuas dej sib txawv, xim liab- kuaj pom lub teeb, ntsuas tensile, thiab ntsuas kev tiv thaiv corrosion, nrog rau kev kuaj pom tus kheej thiab ntsuas hluav taws xob, ua ntej muab tso rau hauv cia. Tsis tas li ntawd, cov rods tseem ceeb yuav tsum tau kho lub cev thiab tshuaj ua ntej siv hauv kev tsim khoom; txwv tsis pub, kev sib txuas ntawm cov tub ntxhais pas nrig thiab silicone roj hmab yuav ua rau cov roj hmab puas. Thaum lub sij hawm tsim khoom, random checks ntawm cov dej diffusion thiab liab - kev ntsuam xyuas lub teeb nqus ntawm cov tub ntxhais pas nrig - sheath interface kuj ua.
Roj Hmab Ntau Lawm (Silicone Rubber)
Silicone roj hmab cov ntaub ntawv muab kev zoo dua hydrophobicity thiab aging kuj piv rau yav dhau los cov ntaub ntawv xws li epoxy resin, ethylene propylene roj hmab, thiab chav tsev - kub vulcanized silicone roj hmab. Yog li ntawd, lawv muaj superior tiv thaiv flashover los ntawm cov pa phem. Tam sim no, cov roj hmab compound formulations yog ntxiv optimized, thiab aluminium hydroxide hmoov cov ntaub ntawv nyob rau hauv lub compound yog ua tiav los ntawm kev ua kom muaj kev kho mob rau ho txhim kho nws hydrophobicity. High-cov khoom siv silicone kawg siv cov khoom siv D4 monomer raw khoom, ntxiv dag zog rau lawv cov kev tiv thaiv kev laus.
Sib tsoo (Fiberglass pas nrig)
Automatic Mandrel Sib Tsoo
Txhawm rau txhim kho kev tsim khoom thiab kev sib koom ua ke ntawm mandrel sib tsoo, peb lub tuam txhab siv lub tshuab sib tsoo los zom cov mandrels. Cov txheej txheem no ua kom ob qho tib si ua haujlwm thiab zoo ntawm mandrel sib tsoo.
Crimping (Cov pas nrig fiberglass thiab qhov kawg fittings)
Cov fittings thiab mandrel yog txuas los ntawm txoj kev crimping. Txij li thaum kawg crimping yuav tsum txuas ob yam khoom sib txawv, peb nruj me ntsis tswj lub elastic modulus, tensile lub zog, compressive zog, thiab structural qhov ntev ntawm ob lub mandrel thiab haum cov ntaub ntawv. Cov qauv haum yog tsim los nrog kev ntxhov siab-relieving arcs kom ntseeg tau tias muaj kev ntxhov siab nyob rau ntawm mandrel. Tag nrho cov txheej txheem crimping yog khoos phis tawj- tswj, thiab cov txiaj ntsig tau raug saib xyuas los ntawm lub ntsuas hluav taws xob acoustic kom paub meej qhov zoo ntawm txhua yam khoom.
Txhaj tshuaj
5.1) Silicone roj hmab yog txhaj rau hauv pwm thiab kho nyob rau hauv qhov kub thiab txias los tsim ib qho kev sib xyaw ua ke. Kev txhaj tshuaj yog nqa tawm hauv ntu raws li qhov kawg ntawm qhov ntev ntawm cov insulator.
Lub hom phiaj ntawm kev txhaj tshuaj molding tshuab yog txhaj cov sheaths thiab sheaths rau hauv cov insulators sib xyaw thiab ua vulcanization molding. Vulcanization yog cov txheej txheem ntawm kev sib txuas ntawm cov khoom siv hluav taws xob zoo heev linear silicon-oxygen molecular qauv compound rau hauv lub network ntawm silicon- cov qauv oxygen molecular nrog cov duab ruaj khov nyob rau hauv qhov kub, siab, thiab lub sijhawm tshwj xeeb. Qhov no crosslinks nrog lub mandrel los tsim ib qho kev sib koom ua ke.
Txhaj tshuaj molding tshuab yog cais los ntawm clamping quab yuam. Feem ntau siv cov tshuab txhaj tshuaj molding rau cov khoom sib xyaw muaj xws li 200, 300, 500, 550, 660, 880, 1100, thiab 1800 tons.
Qhov siab tshaj plaws txhaj tshuaj tuaj yeem ncav cuag 50,000 CC. 300- tuj thiab 500-tuj tshuab yog siv dav tshaj plaws.
5.2) Txhawm rau tiv thaiv eccentricity thaum txhaj tshuaj, mandrel ejector pins yog siv rau sab laug thiab sab xis ntawm cov pwm los tswj cov ntsug eccentricity, thiab lub synchronization bracket yog ntsia rau ntawm cov pwm los tswj kev ntsug eccentricity ntxiv. Lub portable ultrasonic tsis yog -destructive thickness gauge kuj yog siv los xyuas cov sheath thickness los xyuas kom meej tias cov khoom sheath raws li tus qauv yuav tsum tau.
Kev xeem ua haujlwm (hluav taws xob)
6.1) Creepage nrug:
Qhov kev ncua deb tshaj plaws los yog qhov sib npaug ntawm qhov luv tshaj plaws nyob rau saum npoo ntawm cov khoom siv hluav taws xob ntawm ib qho insulator nyob rau hauv ib txwm ua haujlwm voltage.
Lus Cim 1: Qhov saum npoo ntawm cov cement lossis lwm yam tsis yog- cov ntaub ntawv rwb thaiv tsev tsis tuaj yeem suav nrog hauv qhov deb ntawm qhov nkag.
Lus Cim 2: Yog tias qhov siab tshaj - txheej tiv thaiv yog siv rau qhov insulating ib feem ntawm lub insulator, qhov insulating no yog suav hais tias yog ib qho zoo insulating nto, thiab nws qhov deb ntawm qhov chaw yog suav nrog qhov deb ntawm qhov nkag.
6.2) Arcing nrug:
Qhov luv tshaj nyob rau hauv qhov chaw sab nraud ntawm ob qhov hlau ntawm ib qho insulator uas ib txwm nyob rau hauv kev khiav hauj lwm voltage.
6.3) Qhuav xob laim impulse withstand voltage test
Kev ntsuas hluav taws xob qhuav tiv thaiv hluav taws xob yog ua los xyuas kom ntseeg tau tias lub rwb thaiv tsev tuaj yeem tiv taus hluav taws xob-vim hluav taws xob overvoltages nws tuaj yeem raug thaum lub sijhawm ua haujlwm.
6.4) Lub zog ntub dej - zaus kuaj
Qhov kev sim no yog ua los xyuas kom meej tias lub insulator tuaj yeem tiv taus ib qho -feeb fais fab zaus voltage nyob rau hauv ntub dej.
Function Test (Mechanical)
7.1) Kev kuaj pom
Txhua lub insulator yuav tsum tau kuaj xyuas. Mounting ntawm qhov kawg fittings ntawm lub insulating qhov chaw yuav tsum ua raws li cov kos duab. Cov xim ntawm cov insulator yuav tsum yog kwv yees li tau teev tseg hauv cov duab kos. Cov cim yuav tsum ua raws li cov cai ntawm tus qauv no
7.2) Mechanical routine test
Txhua lub rwb thaiv tsev yuav tsum tiv taus, ntawm qhov kub thiab txias, lub zog tensile ntawm RTL sib raug rau 0,5 × SML ( +10 ) % rau tsawg kawg 10 s.
Kos npe
Raws li cov neeg siv khoom xav tau, cov cim tuaj yeem luam tawm ntawm lub tsev los yog ntawm cov fittings. Cov cim ntawm lub tsev yog laser - luam tawm.
