Problems solved by technology

But when the motor is started under heavy load, MKB’s dual-transformer power supply drops rapidly due to the increase in impedance voltage, and the CPU cannot work normally. The advantage of dual-transformer power supply becomes a disadvantage

Abstract

The invention discloses an MKB dual-transformer series power supply device comprising a transient damping circuit. The MKB dual-transformer series power supply device comprises a first transformer, asecond transformer and a CPU circuit, wherein the first transformer and the second transformer are connected in series, and the other side of the second transformer is connected to the CPU circuit tosupply power to a CPU; and the MKB dual-transformer series power supply device further comprises the transient damping circuit, the transient damping circuit is arranged between the first transformerand the second transformer. By setting the transient damping circuit, when a motor is started at heavy load, the CPU can still work normally, and when it is judged that the MKB loses power, that is, when the power supply is turned off, a technician does not have to rush to start a standby motor, the MKB power failure problem can be slightly relieved, and this provides sufficient time for the onsite operators.

Description

technical field [0001] The invention relates to a secondary intelligent terminal equipment of an MCC loop of an electrical system, in particular to an MKB double-transformer series power supply equipment including a transient damping loop. Background technique [0002] MKB intelligent MCC (Motor Control Center) control and protection device is based on the study of similar foreign advanced products and summarizing the typical design experience of a large number of domestic electrical systems. Features A new generation of digital, strong anti-jamming intelligent MCC control and protection device. [0003] MKB series products adopt a modular single product structure, integrating traditional circuit breakers (fuse), contactors, overload (or overcurrent, phase failure) protection relays, starters, isolators, motor comprehensive protectors and other low-voltage The main functions of electrical products include remote automatic control and local direct manual control, panel indic...
