產(chǎn)品簡介

我國電力系統(tǒng)實行兩部制電價：除了收取計量裝置所計量的費用外，還要根據(jù)變壓器容量收取基本電費；對于較大用戶在投運變壓器時還要一次性交納增容費。隨著電力行業(yè)的發(fā)展，用電量的增大，自有變壓器和私人承包變壓器已漸漸占據(jù)了配變中相當(dāng)?shù)姆蓊~，隨之而來的就是個人為了達(dá)到少交費、多用電的目的而采取的各種弄虛作假的手段（主要是改、換變壓器銘牌）；有些用戶年偷電費額達(dá)數(shù)十萬之多，電力部門苦于沒有有效的控制手段。NARL-H變壓器容量及空載負(fù)載測試儀是南澳電氣武漢公司針對這種問題專門開發(fā)、研制的專門用于變壓器容量、損耗參數(shù)測量的高精度儀器。它自帶效能充電電池，不用外接電源即可工作，充電一次可連續(xù)測量幾十至上百臺次；同時，內(nèi)部數(shù)字合成三相標(biāo)準(zhǔn)正弦波信號（絕非簡單的逆變交流輸出，保證了非額定條件下各測試項目測試數(shù)據(jù)的準(zhǔn)確性），經(jīng)功率放大器可提供三相精密交流測試源；在測量變壓器容量和變壓器的短路損耗時不需要外接三相測試電源及調(diào)壓器、升流等輔助設(shè)備，簡化了接線，大大提高了工作效率；容量測試結(jié)果準(zhǔn)確率高。它一種設(shè)備相當(dāng)于二種設(shè)備：有源變壓器容量測試儀+變壓器損耗參數(shù)測試儀。它可對各種變壓器的容量、空載電流、空載損耗、短路損耗、阻抗電壓等一系列工頻參數(shù)可進行精密的測量。該NARL-H變壓器容量及空載負(fù)載測試儀具有體積小、重量輕、測量準(zhǔn)確度高、穩(wěn)定性好、操作簡便易學(xué)等優(yōu)點,完全可取代以往利用多表法測量變壓器損耗和容量的方法，接線簡單，測試、記錄方便，大大提高了工作效率。它以中英文大屏幕圖形式液晶作為顯示窗口，圖形式菜單操作并配有中英文提示，集多參量于一屏的顯示界面，人機對話界面友好，使用簡便、快捷，是各級電力用戶的產(chǎn)品。

Productintroduction

Electricpower system implement two-part tariff: Beside charge by measuredcharge meter, but also charge the basic tariff according totransformer capacity. For big users, who put into transformeroperation, it needs to pay a one-time capacity fee. While with thedevelopment of power industry, electricity consumption isincreasing, the owned transformer and private contractors havegradually occupied a considerable share, and as follows, in orderto pay less, use more, it takes lots of fraudulent means (mainly tochange, alter transformer nameplate). Some users steal electricitycharge reach to hundreds of thousands, the power sector havesuffered no effective means to control yet.

NARL-HTransformer Capacity and Load Load Tester is developed byNANAOELECTRIC company Electricalspecifically for resolving the problem, it’sa high precision instruments developed specifically for transformercapacity and loss parameter measurements. It comes with ahigh-performance rechargeable battery, can work without externalpower supply, the charging time can be measured hundreds timescontinuously; Meanwhile, the internal digital combined asthree-phase standard sine wave signal (not simple inverter ACoutput, which ensure the accuracy of each tested project data underthe non-rated conditions ), the power amplifier can provide precisephase AC testing source; and measure transformer capacity andtransformers three-phase short-circuit loss tests without externalpower source, voltage regulator, voltage booster and otherauxiliary e, simplifying wiring, improved work efficiencygreatly; the accuracy of capacity testing results very high. It canbe used as two kinds of devices: Active transformer capacity tester+ transformer loss parameter tester. It can measure the transformercapacity, load current, load loss, short-circuit loss, impedancevoltage and a series of parameters for precision fres. The NARL-HTransformer Capacity and Load Load Tester has a small size, lightweight, high measuring accuracy, good stability, easy to operateetc., which completely replace the conventional method of usingmulti-table transformer losses and capacity measurement method,simple to connect the wires, test and record, and have greatlyimproved work efficiency. It has a big screen as a graphic LCDwindow, graphical menu operation and with a character prompt, setthe parameters in a multi-screen display interface, interactiveuser-friendly, easy to use, is the preferred product for electricusers at all levels .
