126KV Spring Operation Mechanism

Product Description

The High voltage Spring Operating Mechanism is a stored-energy drive unit for medium-high voltage circuit breakers. It stores energy in compression springs via a charging motor and releases it rapidly to perform closing/opening operations. Key features include a simple structure, high reliability, and wide adaptability to outdoor harsh environments. It complies with IEC 62271.100 and GB 1984 standards, supporting operating cycles like O-0.3s-CO-180s-CO and CO-15s-CO, with a mechanical life of up to 10,000 operations. Main components: camshaft assembly, ratchet assembly, closing spring module, opening spring module, and control unit with auxiliary switches.
