JYL-KK Type 6-35kV Overhead Fault Indicator

Product Introduction

The ring network cabinet online monitoring equipment is mainly suitable for the automation transformation of the traditional ring network cabinet and the switchgear. While realizing two remote (remote signaling, telemetry) functions, detect and locate the position of short circuit and ground fault at the same time, shorten the power outage time and scope. Not only is important for improving the reliability of power supply, but also an indispensable technology for building an intelligent grid.

Advantages

Sampling the zero-sequence current synthesis algorithm, canceling the traditional zero-sequence transformer design, synthesizing the zero-sequence current by detecting the phase sequence to identify the single-phase ground fault, and effectively solving the situation where it is not convenient to install the zero-sequence transformer;
5A self-powered, the acquisition unit uses high magnetic permeability material CT, combined with low-power system design, to ensure that the primary current 5A achieve battery-free full-function operation, improve reliability;
Instead of using the traditional one-time battery power supply scheme, the three-level power architecture of CT power supply, supercapacitors, and non-rechargeable lithium batteries is adopted to guarantee the reliable operation of the equipment;
Electronic current transformer for current and ground electric field detection, It has great linearity of test data and is not affected by wire diameter, thus guarantee test accuracy;
Collection unit indicates failures locally and centrally, eliminating the need to install display panels in every interval;
The energy opening CT is made of anti-rust and anti-corrosion materials, supplemented by a high-level cutting process to ensure that the outdoor environment provides sufficient power for the equipment;
Both the collection unit and the acquisition unit can be controlled remotely and wirelessly.
