開關柜通電測試臺/高低壓通電測試儀測量部位包括：

(1)母線連接(jie)處以及(ji)其他元器件與母線的連接(jie)處。

(2)抽屜式設備(bei)的(de)母線室(shi)、功能單元室(shi)和電纜室(shi)的(de)空間。

(3)可觸及的門、手(shou)柄和(he)覆板。

以上(shang)三種部位均(jun)應盡量選(xuan)產生溫(wen)升高點進行測量。當溫(wen)度(du)(du)變(bian)化不超過1℃／h時，則(ze)可記(ji)錄其溫(wen)升值(zhi)。其值(zhi)應不超過有關標準的規定值(zhi)。裝置內絕緣沒有破壞，元器件在(zai)設備內的溫(wen)度(du)(du)條(tiao)件下正常工作，則(ze)溫(wen)升試驗合格(ge)。

本公(gong)司生產(chan)的(de)(de)開關柜通電(dian)測(ce)試(shi)(shi)(shi)(shi)臺(tai).通電(dian)測(ce)試(shi)(shi)(shi)(shi)儀(yi)介電(dian)性能(neng)試(shi)(shi)(shi)(shi)驗(yan)應根據各(ge)回路額定絕緣電(dian)壓(ya)(ya)分(fen)別(bie)進行試(shi)(shi)(shi)(shi)驗(yan)。應將(jiang)那些不能(neng)耐受這種試(shi)(shi)(shi)(shi)驗(yan)電(dian)壓(ya)(ya)的(de)(de)電(dian)器元件(jian)(如電(dian)子設備、電(dian)容器等)從電(dian)路中(zhong)拆除。 施加試(shi)(shi)(shi)(shi)驗(yan)電(dian)壓(ya)(ya)的(de)(de)時間和方法：出廠試(shi)(shi)(shi)(shi)驗(yan)為1s點試(shi)(shi)(shi)(shi)。型式試(shi)(shi)(shi)(shi)驗(yan)為1min，施加電(dian)壓(ya)(ya)從30%～50%的(de)(de)試(shi)(shi)(shi)(shi)驗(yan)電(dian)壓(ya)(ya)開始，約5s升到規定值。1min后(hou)將(jiang)試(shi)(shi)(shi)(shi)驗(yan)電(dian)壓(ya)(ya)逐漸降到零。

如果設備已經過一次耐壓試(shi)驗，而需(xu)再(zai)試(shi)驗時，電壓應(ying)降到規定值的85%，試(shi)驗時間為11s。
