The circuit breaker operating mechanism is the core device enabling the mechanical operation of high-voltage switchgear in electrical engineering. Its primary functions are to precisely control the opening and closing operations of circuit breakers and maintain a stable closed position. Classified by power source, there are four main types: electromagnetic, spring-operated, hydraulic, and pneumatic. Hydraulic mechanisms utilize high-pressure hydraulic oil for efficient closing. These mechanisms are widely used for operating high-voltage disconnectors, controlling intelligent circuit breaker interruption, and in automatic transfer switch (ATS) systems. Recent research has focused on optimizing interruption speed and reliability through dynamic Simulering .

Energilagring

Kontrollera om produkten har deformerats under transporten . Installera och fixa mekanismen på omkopplaren, sätt in det dedikerade driftshandtaget i den nedre högra delen av mekanismen och rotera den medurs (eller ström på elmotorn) tills ett "klick" -ljud görs för att slutföra energilagringsåtgärden .}

Avslutningsverksamhet

Turn the green knob, and the main circuit of the circuit breaker switch will close under the action of the mechanism spring force. When operating electrically, the live mechanism of the closing coil is fully closed for operation, and the opening spring is stored for energy at the same time. At this point, energy storage can be carried out again, but the closing operation cannot be performed (with interlocking).

Öppningsoperation

Vrid den röda knoppen, och huvudkretsen för brytarbrytaren öppnas under mekanismens verkningsverk . eller när den manövreras elektriskt, öppnas den levande mekanismen för öppningsspolen helt för drift .}}}
