NL ACOUSTICS聲學(xué)成像儀NL CAMERA產(chǎn)品介紹
NL Camera是一款易于使用的獨立設(shè)備，用于在例行檢查期間檢測和定位中壓和高壓電氣系統(tǒng)中的局部放電 (PD)。 NL Camera利用 124 個麥克風(fēng)來檢測和定位局部放電發(fā)出的聲音，即使這些聲音是人耳完全聽不到的。 PD 在組件開始升溫之前開始發(fā)出聲音，NL Camera可以在早期階段檢測到問題。
NL Camera立即在屏幕上顯示所定位的局部放電，使用戶能夠輕松查明并報告可能的問題。 NL Camera可遠(yuǎn)距離快速掃描大面積區(qū)域，從130多米外定位電網(wǎng)問題。 NL Camera自動檢測 50 和 60 Hz 局部放電并實時顯示相位分辨局部放電 (PRPD) 模式。
The NL Camera is an easy-to-use, stand-alone device for detecting and localizing partial discharges (PD) in medium- and high-voltage electrical systems during routine inspections. The NL Camera utilizes 124 microphones to detect and locate sounds emitted by partial discharges – even when they are completely inaudible to the human ear. PDs begin emitting sound before components start to heat up, and the NL Camera enables problems to be detected at an early stage.
The NL Camera instantly shows the located partial discharges on the screen, allowing users to pinpoint and report possible problems effortlessly. The NL Camera quickly scans large areas from a distance, locating problems in power grids from more than 130 meters away. The NL Camera detects 50 and 60 Hz partial discharges automatically and displays the phase-resolved partial discharge (PRPD) pattern in real time.
