Power supply distribution unit capable of time-sharing power supply

Abstract

The invention provides a power distribution unit which is time-sharing charge and belongs to the industry control technique field. The structure thereof comprises a power supply plug row, a logic control unit, an input terminal connector and an AC-DC converting circuit; the input terminal connector is connected with the power supply, and provides the power distribution device with full power, the power supply plug row is connected with the logic control unit through a signal winding displacement, the AC-DC converting circuit can convert 220V voltage AC to 5V TTL voltage DC in switching power supply way which can be supplied for the logic control unit, the device adopts a single-chip as a delay output logic controller, and collects the delay setting on the control panel, thus reaching the effect of respectively controlling the switch circuit of each plug and executing accurate time-sharing charge thereof. The device also can measure and display the total load current and provide overcurrent protection. The invention can solve the problem that the instant current which is caused by multi-load in industrial application charged simultaneously is too big so as to bring device damage and electric fence fluctuation, thereby improving the reliability and security of the device.

Description

(1) Technical field [0001] The invention relates to an industrial control technology, in particular to a power distribution unit which uses a single-chip microcomputer as a logic control center and realizes a time-sharing power-on function. (2) Technical background [0002] Power distribution technology can be applied to almost all fields that require electrical energy. In civil occasions, since the number of loads is generally not large and the power is not large, the importance of power distribution is ignored, and no matter how the distribution is used, it will not have a significant impact on the use of users; while in industrial applications In the environment, it is often accompanied by the intensive use of a large number of devices, and the power is also high. Whether the power distribution can be effectively carried out is related to the safety of devices and applications. [0003] When the equipment starts, it will generate an instantaneous starting current. Depend...

AI Technical Summary

Problems solved by technology

[0004] Existing power distributors often use manual operation to control the power-on of load equipment, which is cumbersome when operating a large number of equipment, not only wastes time, but is also prone to errors; some power distributors do not even have manual control. Direct power supply after the load is applied, and the requirement of time-sharing start-up cannot be guaranteed, which may easily cause damage to the power supply equipment and impact the power grid; because there is generally no embedded software, the power-on strategy is restricted by hardware conditions and is very simple
