Description

Technical Field

[0001] The utility model relates to the electrical field, in particular to a decentralized DTU fast power-on device. Background Art

[0002] Switchgear power-on devices can provide various AC or DC power supplies and facilitate switchgear testing. They are widely used in industrial production and have the characteristics of stable and reliable output and high integration. However, when the power-on device is currently in use, the testing of distributed DTUs must rely on the overall assembly progress of the complete equipment. Due to the large number of components and complex electrical connections in 10kV switchgear, the distributed DTU is the electrical core component of the complete equipment. The testing of distributed DTUs must wait until the complete equipment is assembled before the power-on test can be carried out. The testing phase is seriously delayed. If the distributed DTU is found to fail the test, it needs to be replaced or modified, which seriously affects the switchgear supply cycle or the time it takes to restore power after on-site power outages and modifications.
