BJ8830接地電阻測(cè)試儀產(chǎn)品介紹
BJ8830接地電阻測(cè)試儀是一款采用先進(jìn)DC/AC變換技術(shù)的新型測(cè)量設(shè)備，適用于電力、通信、鐵路等行業(yè)對(duì)各類裝置接地電阻及低電阻導(dǎo)體電阻值的精確測(cè)量。該設(shè)備摒棄傳統(tǒng)手搖發(fā)電方式，通過中大規(guī)模集成電路實(shí)現(xiàn)三端鈕和四端鈕測(cè)量方式的集成化設(shè)計(jì)。其工作原理是通過機(jī)內(nèi)變換器將直流轉(zhuǎn)為低頻交流恒流，經(jīng)輔助接地極形成回路后測(cè)量被測(cè)物上的交流壓降，最終通過LCD顯示屏直觀呈現(xiàn)測(cè)量結(jié)果。設(shè)備提供0～2Ω、0～20Ω、0～200Ω三個(gè)量程范圍，可滿足不同場(chǎng)景的測(cè)量需求。13
產(chǎn)品特點(diǎn)與結(jié)構(gòu)設(shè)計(jì)
該測(cè)試儀采用高強(qiáng)度鋁合金外殼，具備優(yōu)良的抗干擾能力，這得益于鎖相環(huán)同步跟蹤檢波技術(shù)和開關(guān)電容濾波器的應(yīng)用。設(shè)備允許輔助接地電阻在0～2kΩ（Rc）和0～40kΩ（Rp）之間變化而不影響測(cè)量精度，且無(wú)需人工調(diào)節(jié)平衡。除接地電阻測(cè)量外，還可進(jìn)行土壤電阻率及交流地電壓的檢測(cè)。設(shè)備配備312位LCD顯示屏，當(dāng)測(cè)試回路不通時(shí)會(huì)顯示"1"提示溢出，符合常規(guī)操作習(xí)慣。整機(jī)體積為220×200×105mm，重量不超過1.4kg，采用6節(jié)5#鎘鎳充電電池供電，支持外接220V交流電源充電，最大功耗低于2W。138
BJ8830 Ground Resistance Tester Product Overview
The BJ8830 ground resistance tester is an innovative measuring device employing advanced DC/AC conversion technology, designed for precise measurement of grounding resistance in power systems, telecommunications, and railway applications. This integrated instrument combines three-terminal and four-terminal measurement methods through large-scale integrated circuits, eliminating the need for traditional manual generator operation. Its operating principle involves converting DC to low-frequency AC constant current through an internal transformer, then measuring the AC voltage drop across the test object via auxiliary grounding electrodes, with results displayed on an LCD screen. The device offers three measurement ranges: 0-2Ω, 0-20Ω, and 0-200Ω to accommodate various testing scenarios.13
Design Features and Technical Specifications
Featuring a durable aluminum alloy casing, this tester demonstrates exceptional anti-interference capability due to its phase-locked loop synchronous tracking detection and switched capacitor filter technology. It maintains measurement accuracy even with auxiliary grounding resistance variations between 0-2kΩ (Rc) and 0-40kΩ (Rp), requiring no manual balance adjustment. Beyond grounding resistance measurement, it can evaluate soil resistivity and AC ground voltage. The 312-segment LCD display shows "1" to indicate open-circuit conditions, following conventional measurement conventions. With compact dimensions of 220×200×105mm and weighing under 1.4kg, it operates on six rechargeable 5# Ni-Cd batteries (also supporting 220V AC charging) while maintaining power consumption below 2W. The instrument s portable design and multifunctional capabilities make it suitable for field applications across multiple industries.138
