Abstract: This paper designed a direct-acting permanent magnetic actuator of solid-insulated ring main unit, adopting the exciting mode in which the charged capacitors discharged to drive the permanent magnetic actuator. According to the contact counter-force of circuit breakers arc extinguish chamber and separating brakes spring, the counter-forces were carried out reduction and the finite element model was built to carry out dynamic simulation. The action current of direct-acting permanent magnetic actuator was simulated, as well as the divide-shut brake speed of ring main units. Via the assembling debugging of ring main unit prototype, the action current of direct-acting permanent magnetic actuator was measured, together with mechanical characteristics data of ring main unit switch. The test results verify the accuracy of thetheory simulation design.
Key words: solid-insulated ring main unit; direct-acting permanent magnetic actuator; mechanical characteristic; finite element method
