6KA reclosing device TDRDL-C

Talemod TDRDL-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 6KA.

Product Overview

Talemod reclosing device is a fundamental protection equipment for distribution networks, specifically designed to automatically restore power supply after the elimination of transient line faults. Based on time-sequence logic control principle, the device automatically performs 1-3 reclosing operations according to preset time delays after circuit breaker tripping due to faults. Its core value lies in effectively addressing transient faults caused by lightning strikes, bird contact, etc., reducing outage time caused by non-permanent faults, and improving power supply continuity.

Core Functions

Standard Reclosing Sequence: Supports "open-close-open-close-open" standard operation cycle with adjustable reclosing times.

Precise Time Delay Control: Provides adjustable delay settings from 0.5-300 seconds to meet different differential coordination requirements.

Lockout Logic Protection: Automatically locks out when reclosing onto permanent faults, preventing multiple impact damage to equipment.

Local Manual Operation: Equipped with local operation knob, supporting operation/withdrawal/test mode switching.

Main Application Fields

Rural Distribution Systems: 10kV overhead line section circuit breakers.

Industrial Power Supply Lines: Protection for mining area power supply mains.

Suburban Distribution Networks: Fault handling for long-distance radial lines.

Simple Branch Lines: Distribution transformer high-voltage side control.

Temporary Power Systems: Construction power supply protection.
