Ang DGXK2 Large-Capacity High-Speed Current-Limiting Switchgear usa ka integrated protection device nga gi-design pinaagi sa medium ug high voltage (mainly 35kV/110kV) large-capacity power distribution systems. Gitagad niini ang high-speed switching technology, intelligent current-limiting algorithms, ug complete cabinet structures. Ang iyang core function mao ang quick response within ≤10ms human natapos ang short-circuit fault, pinaagi sa logic sa "first limiting current, then breaking", suppressing the actual short-circuit current peak in the fault circuit to 15%-50% of the expected value, ug then safely cutting off the fault circuit.

Kini nga device makapuyo og independent application sa power plant branch busbars ug industrial park main distribution lines, pero usab mahimo nimong ipasabot sa complete cabinets uban sa vacuum circuit breakers, disconnectors, ug uban pang equipment, adapting to indoor/outdoor multi-scene installation. Ang iyang design purpose mao ang solve anang pain points sa large-capacity power distribution systems sama sa "equipment burnout caused by excessive short-circuit current" ug "accident expansion caused by slow response of traditional switches". Sa parehas nga panahon, gitakda niini ang requirements for dynamic ug thermal stability parameters sa transformers, cables, ug uban pang equipment sa power grid, helping the power system achieve the dual goals of "safety protection + cost optimization".

Features

• Dual Advantages of Large-Capacity Carrying and High-Speed Breaking：The rated current covers 630A-2500A, and the rated breaking current can reach 200kA, meeting the large-capacity power supply needs of large industrial parks and regional distribution networks; the breaking time is ≤10ms, which is much faster than traditional circuit breakers (30-50ms), and can complete fault isolation before the short-circuit current rises to the peak, avoiding the equipment from bearing extreme impacts.

• Significant Current-Limiting Characteristics, Reducing System Losses：Built-in dedicated current-limiting module, through the synergistic effect of electromagnetic induction and mechanical braking, controls the actual short-circuit current peak to 15%-50% of the expected value, greatly reducing the electric power impact of short-circuit current on generators and transformers, while reducing power loss during faults, indirectly improving power grid operation efficiency.

• Multi-Scenario Adaptation, High Installation Flexibility：Supports two installation environments: indoor (IP4X protection) and outdoor (IP54 protection), adapting to different climatic conditions; it can be installed separately at key nodes of the line, or assembled into complete cabinets with vacuum circuit breakers, load switches, etc. (such as TXB3 series cabinets), meeting the diversified layout needs of "decentralized protection + centralized management and control" of the power grid.

• Intelligent Integrated Design, Convenient Operation and Maintenance：Integrated with electronic measurement and control unit and condition monitoring module, it can collect real-time operating data such as current and temperature, supports remote communication (compatible with Modbus and IEC 61850 protocols), facilitating operation and maintenance personnel to remotely monitor equipment status; the structure adopts a modular design, and core components can be disassembled and replaced, without the need for overall power outage during maintenance, shortening the power outage time.
