MV Three Phase Load Break Recloser

The MV Three Phase Load Break Recloser is a medium-voltage three-phase integrated equipment that integrates load switch operation function and recloser protection function. It can not only realize frequent switching of normal load current, but also has short-circuit fault protection and automatic reclosing functions. One machine serves multiple purposes, greatly reducing equipment procurement and project construction costs. This product adopts special load contacts and arc extinguishing system, with excellent load breaking capacity, and can frequently operate the load current of distribution lines. At the same time, it is equipped with short-circuit protection and automatic reclosing logic. When a short-circuit fault occurs, it automatically removes the fault and tries to reclose to restore power supply. As a medium-voltage three-phase load break recloser, it is especially suitable for distribution scenarios that require frequent load switching and automatic fault recovery, and is a multifunctional protection and control equipment for medium-voltage distribution networks.

In terms of technical performance and scenario adaptability, this load break recloser adopts vacuum arc extinguishing technology. The load contacts are made of wear-resistant alloy material, resistant to arc erosion, and can withstand frequent load switching operations. Its mechanical life and electrical life are both better than conventional equipment. The equipment is equipped with a permanent magnet operating mechanism, with stable and reliable action and fast opening and closing speed, which can meet both the stability requirements of load operation and the rapidity requirements of fault removal. The whole equipment adopts outdoor pole-mounted design, with a protection grade of IP65, convenient installation and maintenance-free operation. Combined with the actual operation needs of medium-voltage distribution networks, we have optimized the load breaking performance and reclosing protection logic of the product, ensuring reliable protection function even under the scenario of frequent load switching, and providing customers with an integrated solution integrating control and protection.

Application Fields

 

• Load control and protection of medium-voltage distribution lines
• Lines with frequent load switching in industrial parks
• Distribution circuits of commercial complexes
• Sectional control of rural power grids
• Nodes of ring network distribution lines

We have established special quality inspection standards for load switch products, focusing on load breaking performance and mechanical operation life. Starting from the incoming of core components, we conduct consistency screening and performance tests on load contacts and interrupters to ensure that the components meet quality standards. Each process in the production process is set with exclusive quality inspection nodes. Before delivery, finished products must pass full inspections such as load breaking test, short-circuit breaking test, mechanical operation life test, and environmental adaptability test. A 100% full inspection system is implemented, and each product is accompanied by a detailed performance inspection report. We support third-party authoritative inspection, and can cooperate in completing various performance verification work to ensure the reliable quality of delivered products.

We adopt a standardized industrial equipment packaging scheme. The interior of the product is fully wrapped with shock-proof foam and moisture-proof film, and the exterior is packed with reinforced wooden cases, which can effectively resist shock and vibration during long-distance transportation. For batch orders, we can customize packaging schemes according to transportation methods and destinations to ensure safe delivery of products under different transportation methods such as sea transportation and land transportation. We mainly support FOB trade terms, be responsible for the costs of transporting goods to the port and customs declaration, and also negotiate EXW, DDP and other trade terms according to customer needs, fully ensuring the safe and timely delivery of goods.

We provide a one-year whole-machine warranty and lifetime technical support for this product. The after-sales team can respond to customers' technical consultation and problem feedback within 24 hours, and provide original genuine spare parts supply and professional maintenance services. For industrial scenarios with frequent operations, we can provide regular inspection and maintenance services to extend the service life of equipment. At the same time, we regularly conduct customer return visits, collect equipment operation data and use suggestions, continuously optimize the load operation performance and reliability of the product, and provide customers with long-term reliable equipment guarantees.
