Overhead External Signal-Type / Transient Characteristic-Type Remote Fault Indicator JYW/Z-HD
Currently, most distribution networks employ small-current grounding systems. When a single-phase ground fault occurs in such systems, the fault current is low and the fault characteristics are complex, making line selection and fault location for single-phase ground faults a persistent technical challenge in distribution network operation. Accurately identifying the grounded line and pinpointing the faulted section while maintaining continuous power supply remains a critical issue. The signal source detection method (asymmetric current) for detecting single-ground faults operates on the principle of leveraging the unique characteristics of single-phase ground faults in small-current grounding systems—specifically, by analyzing the distinctive features of asymmetric current signals generated on the faulted line to achieve both line selection and fault location.
Overhead Transient Recording Remote Fault Indicator JYL
The distribution network fault location system is a simple and practical distribution automation solution. The waveform recording–based fault location system consists of a master station backend, data acquisition units, aggregation units, supporting communication terminals, and a public communication network. It is suitable for online monitoring of overhead lines ranging from 3 to 35 kV, offering functions such as line fault aggregation and proactive reporting of fault information to the master station. It features ease of use, stable operation, convenient maintenance, high reliability, excellent openness, and cost-effectiveness.
S13 Series Fully Sealed Laminated Core Transformers
The S13 series fully sealed, stacked-core oil-immersed transformers utilize high-permeability cold‑rolled grain-oriented silicon steel sheets with a thickness of 0.23–0.3 mm for the core. They feature 45-degree full‑lapped joints and a stepped stacking method, with no punching and binding using semi‑dry, non‑woven glass fiber tape, effectively reducing no‑load losses and operating noise.
S13-M·RL Series Three-Dimensional Rolled Core Transformer
The S13-M·RL series of three-dimensional core oil-immersed transformers breaks away from the traditional planar design and adopts a three-phase symmetrical three-dimensional structure. The magnetic circuits of the transformer’s three-phase cores are perfectly symmetrical, significantly reducing magnetic reluctance and leading to a marked decrease in excitation current and no-load losses. The core is fully solidified into a single unit, greatly enhancing its mechanical strength and seismic resistance, while also lowering operating noise and resulting in a more compact structure. With numerous advantages such as energy efficiency, environmental friendliness, stable and reliable performance, and anti-theft features, these transformers are fully aligned with China’s national energy conservation policies.
S(B)H15 Series Amorphous Alloy Core Transformers
The S(B)H15 series amorphous alloy oil-immersed transformers feature low magnetizing power, high resistivity, and minimal eddy current losses, resulting in exceptionally low no-load performance. They are particularly well suited for use in urban residential communities and on rural power grids with low load factors and long no‑load periods. These transformers are the ideal equipment for lighting and power consumption in both urban and rural areas, and represent an ideal replacement and upgrade for distribution transformers.
