Abstract
The invention relates to a transfer mechanism of dual-power supply high-speed automatic transfer switching equipment. The transfer mechanism mainly comprises a closing coil mechanism, an A power supply square shaft assembly, a connecting rod mechanism, a B power supply square shaft assembly, a power spring, a latch spring, a latch slide block, a tripping coil mechanism, a box body, a static contact assembly and a moving contact assembly. The transfer mechanism adopts double-excitation and spring mechanisms to provide drive force; power can be transferred by the simple and reliable square shaft assemblies; and the coil is instantaneously closed to finish tripping or transferring. An A power supply is transferred to a B power supply by a spring operation and a latch mechanism; and instantaneous transferring when a normal power supply is normal is achieved, so that a load is powered off for at most 5ms. Instantaneous transferring when the normal power supply is broken down is achieved, so that the load is powered off for at most 20ms. The B power supply is transferred to the A power supply by electromagnet attraction and the latch mechanism; an A power supply drive shaft is connected with a B power supply drive shaft through a connecting rod; and the condition that two paths of power supply parts cannot be simultaneously on is ensured, so that mechanical interlocking is achieved.
