10KA reclosing device TDRDM-C

Talemod TDRDM-C is a crucial piece of automated protection equipment in power systems, primarily installed on circuit breakers in transmission and distribution lines, especially overhead lines. Its core purpose is to automatically restore power after a temporary fault occurs on the line, thereby significantly improving power supply reliability and continuity. The product is applied to the lines with AC 50/60Hz, rated voltage of 240/415V, and rated working current up to 63A. The rated short-circuit breaking capacity has 10KA.

Product Overview

The automatic reclosing device is an intelligent power distribution protection equipment specifically designed for transient fault self-healing and permanent fault lockout. Through real-time line status monitoring by microprocessors, it performs multiple automatic reclosing attempts according to preset programs after fault tripping. Its core value lies in effectively distinguishing between transient and permanent faults, significantly reducing power outages caused by instantaneous events such as lightning strikes and tree contact, thereby enhancing power supply reliability and intelligent management capabilities.

Core Functions

Intelligent Fault Identification: Utilizes voltage-time or current-time criteria to accurately determine fault characteristics

Adaptive Reclosing: Supports 1-3 programmable reclosing attempts with adjustable delay time (0.1-300 seconds)

Fault Recording: Captures the last fault current waveform, supporting fault analysis and location

Communication Networking: Equipped with RS485/Ethernet interfaces, supporting remote monitoring through SCADA systems

Main Application Fields

Distribution Network Lines: 10kV overhead line section switches, cable branch boxes

New Energy Stations: PV plant collection lines, wind farm box transformer outlets

Industrial Power Supply: Critical load supply lines, mining dedicated line protection

Rural Power Grids: Long-distance radial lines, mountain area distribution lines

Public Facilities: Airport power supply ring main units, metro traction power supply systems
