PJY238型絕緣油介電強(qiáng)度測(cè)定儀

儀器特點(diǎn)

1、PJY238型絕緣油介電強(qiáng)度測(cè)定儀為單油杯結(jié)構(gòu)，采用微機(jī)控制，可自動(dòng)完成升壓、保持、降壓、攪拌、靜放、顯示計(jì)算、打印等一系列操作，可在  0-80KV范圍內(nèi)進(jìn)行絕緣油耐壓測(cè)試。 
2、采用大屏幕點(diǎn)陣液晶顯示器，內(nèi)部具有背光系統(tǒng)，即使在夜間也能清晰可見(jiàn)，測(cè)試過(guò)程通過(guò)漢字菜單提示，可方便試驗(yàn)人員操作。 
3、本儀器操作簡(jiǎn)單，操作人員只需按使用說(shuō)明輸入簡(jiǎn)單指令，儀器將會(huì)按照設(shè)置自動(dòng)完成絕緣油的耐壓測(cè)試。每次擊穿電壓值會(huì)自動(dòng)存儲(chǔ)，測(cè)試完成后，可打印或存儲(chǔ)各次擊穿電壓值和平均值。 
4、本儀器適應(yīng)性較強(qiáng)，攜帶方便，可用于實(shí)驗(yàn)室及戶(hù)外現(xiàn)場(chǎng)測(cè)試。儀器還具有較強(qiáng)的抗干擾能力，可以在強(qiáng)電磁場(chǎng)環(huán)境下正常工作。 
5、本儀器具有過(guò)壓、過(guò)流、自動(dòng)回零、接地等保護(hù)裝置，在正常使用情況下，*保證儀器本身及操作人員的安全。 
6、升壓速度和靜置、間隔時(shí)間可根據(jù)不同的實(shí)驗(yàn)標(biāo)準(zhǔn)選擇。 
7、本儀器同時(shí)兼容國(guó)標(biāo)2002版和1986版測(cè)試，可根據(jù)要求自定義測(cè)試條件。
