一、 功能特点及用途
1、 单机可以完成1000kVA以下的配电变压器全电流下的负载试验;在三分之一额定电流下可完成2500kVA以下的配电变压器的负载试验(在三分之一的额定电流下,仪器可换算到额定电流下的负载损耗参数。)。
2、 单机可以完成6300kVA以下的配电变压器的容量试验和容量检测。自带的试验电源一次充电可以完成100台2500kVA配电变压器容量的试验。根据变压器空载损耗试验结果,可以判断出变压器的型号。
3、 240*120超大蓝屏液晶显示器,中文操作菜单,高速打印机打印试验结果和历史记录。
4、 以高性能的处理器作为控制和运算的核心,采样速度快,数据的稳定性好。
5、 可外接电压互感器和电流互感器可拓宽仪器的测量范围。
6、 电流、电压采样不经过互感器直接采样,大大提高了仪器的测量范围和测量精度,优于市面大多数同类仪器。
7、 仪器的体积小、重量轻、便于携带。适用于试验室与现场测试和操作规程。
8、 HRKFR变压器空载负载及容量分析综合测试仪是按照并符合 JB/T501-91《电力变压器试验导则》和GB1094-96《电力变压器》的技术标准要求研发设计生产的。

1) Functions, features and use
A. Single machine can complete under 1000kVA distribution
transformers and full-electric flow load test; About a third
of the rated power flow can be completed under 2500kVA distribution
transformers load test(About a third of the rated flow,
electric instrument can be converted to the rated flow load
loss electric parameters).
B. Single machine can complete under 6300kVA distribution
transformer capacity experiment and capacity test. Self-contained
test power can charge 100 sets of 2500kVA distribution transformer
capacity test in one time. According to the experiment results,
transformer no-load loss can judge the transformer models.
C. 240 * 120 large blue LCD, Chinese operation menu, high-speed
printers print test results, and the historical record.
D. With high-performance processor as the core of control
and operation. Sampling speed. The data stability is satisfactory.
E. It can external voltage transformer and current transformer
can broaden instrument measurement range.
F. Current, voltage transformer, sampling don't pass through
mutual inductor but take samples directly, greatly improved
instrument measurement range and accuracy of measurement,
better than most of the similar instruments in the market.
G. They are small, light and easy to carry, and are suitable
for laboratory and field test and operation procedures.
H. HRKFR transformer no-load loading and capacity of comprehensive
analysis instrument is according to JB/T501-91(Power Transformer
Test Guidelines) and GB1094-96 <Power Transformer>.
