ZX56開(kāi)關(guān)式直流標(biāo)準(zhǔn)電阻箱
產(chǎn)品概述
ZX56開(kāi)關(guān)式直流標(biāo)準(zhǔn)電阻箱是一種可調(diào)節(jié)電阻值的精密測(cè)量工具，適用于直流電路中的電阻調(diào)節(jié)與校準(zhǔn)。該設(shè)備通過(guò)多組十進(jìn)開(kāi)關(guān)實(shí)現(xiàn)阻值的階梯式變化，調(diào)節(jié)范圍覆蓋0.01Ω至11111.11Ω，最小步進(jìn)值為0.01Ω，能夠滿(mǎn)足實(shí)驗(yàn)室、工廠(chǎng)及科研單位對(duì)電阻精度的高要求。其核心電阻元件采用高穩(wěn)定性錳銅合金線(xiàn)無(wú)感繞制，結(jié)合瓷管基底與嚴(yán)格工藝處理，確保長(zhǎng)期使用的穩(wěn)定性和可靠性。面板設(shè)計(jì)簡(jiǎn)潔，讀數(shù)示值排列成直線(xiàn)，便于快速識(shí)別當(dāng)前阻值。17
技術(shù)特點(diǎn)
ZX56采用六組開(kāi)關(guān)結(jié)構(gòu)，每組開(kāi)關(guān)通過(guò)旋鈕獨(dú)立調(diào)節(jié)，接觸部分采用微彈簧壓緊技術(shù)，有效減少長(zhǎng)期使用導(dǎo)致的接觸電阻變差。電阻支座選用高絕緣聚砜塑料，絕緣性能優(yōu)異，保障操作安全。設(shè)備工作環(huán)境要求為溫度+10℃～+35℃，相對(duì)濕度30%～80%，適合常規(guī)實(shí)驗(yàn)室條件。使用前需旋轉(zhuǎn)各組旋鈕確保接觸穩(wěn)定，并定期用中性清潔劑維護(hù)電刷片以延長(zhǎng)壽命。其設(shè)計(jì)兼顧實(shí)用性與耐用性，尤其適合電學(xué)測(cè)量、儀器校驗(yàn)等場(chǎng)景。1519
應(yīng)用場(chǎng)景
該電阻箱廣泛應(yīng)用于教育、工業(yè)及科研領(lǐng)域。在教學(xué)中，可用于演示電阻變化對(duì)電路的影響；在工廠(chǎng)中，可校驗(yàn)便攜式直流電橋或作為精密電阻源；在科研中，支持各類(lèi)電學(xué)實(shí)驗(yàn)的數(shù)據(jù)采集。其寬泛的阻值范圍和精細(xì)的步進(jìn)調(diào)節(jié)能力，使其成為多場(chǎng)景下的理想工具。此外，設(shè)備結(jié)構(gòu)緊湊（約200×150×110mm，重1.3kg），便于攜帶與安裝。424
Product Overview
The ZX56 switch-type DC standard resistance box is a precision adjustable resistor designed for DC circuit calibration and resistance regulation. It features a stepwise resistance adjustment from 0.01Ω to 11111.11Ω with a minimum increment of 0.01Ω, achieved through six decade switches. The resistance elements are wound with high-stability manganin alloy on ceramic tubes, ensuring long-term stability under rigorous processing. The clear linear scale on the panel facilitates quick reading. Ideal for laboratories and industrial settings, it supports accurate electrical measurements.17
Technical Highlights
With a six-switch design, the ZX56 employs micro-spring compression technology to minimize contact resistance drift. The high-insulation polysulfone base enhances safety, while the operating range of +10℃～+35℃ and 30%～80% humidity suits typical lab conditions. Users should rotate switches before operation for stable contact and perform periodic maintenance on brush contacts. Its durability and precision make it suitable for calibrating instruments like DC bridges or serving as a reliable resistance source.519
Applications
This resistance box is widely used in education, industry, and research. It demonstrates circuit resistance effects in classrooms, verifies portable DC bridges in factories, and aids precise data collection in scientific experiments. Compact dimensions (200×150×110mm, 1.3kg) and broad resistance range ensure versatility across scenarios. Its user-friendly design balances functionality and portability.424
