Multi-power-source automatic converting system

Abstract

The invention provides a multi-power-source automatic converting system, comprising at least one controller and an integration unit connected with at least one controller. The integration unit comprises an adapter, an electric operation mechanism and a circuit breaker, wherein the circuit breaker and the electric operation mechanism are mounted on a power supply automatic conversion device; the circuit breaker and the adapter are connected with a power supply wire; the adapter is connected with the circuit breaker, the electric operation mechanism and the controller simultaneously; and the electric operation mechanism is connected between the circuit breaker and the adapter. The multi-power-source automatic converting system provided by the invention uses a modulation design; and each module can be individually mounted, so that the multi-power-source automatic converting system is flexible and convenient to mount, and is applicable to the field and the large-size production with higher space arrangement requirement. Furthermore, the multi-power-source automatic converting system can be used for forming the integration units and the controller with different quantities to a power supply converting system with different functions, particularly a complex multi-power-source converting system, so that the defect that a PLC (Programmable Logic Controller) is difficult to develop, and the functions are flexible. Each integration unit is individual and has the advantages of convenience in maintenance and low maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a multi-power automatic conversion system. Background technique [0002] In some industries that require high continuity of power supply, such as petrochemical, metallurgy, telecommunications, hospitals, etc., once the power is cut off, it will cause great losses. or generator. In such occasions, dual power supply automatic switching devices are usually used for switching. In a very small number of power supply places, such as communication equipment rooms, when it is necessary to switch between 3 or even multiple power sources, a multi-power automatic conversion system composed of PLC as the control core and auxiliary devices is often used. [0003] However, the installation size of the traditional dual-power automatic conversion device is generally fixed, and the busbar wiring needs to be combined with the installation size of the device, and once the...

AI Technical Summary

Problems solved by technology

[0003] However, the installation size of the traditional dual-power automatic conversion device is generally fixed, and the busbar wiring needs to be combined with the installation size of the device, and once the size deviates, it will lead to installation difficulties, especially when renovating old power distribution rooms. this kind of situation

[0004] However, the multi-power automatic conversion system composed of PLC as the control core is difficult to realize, the maintenance cost is high, the function is not flexible, the system integration is inconvenient, and it cannot meet the requirements of mass production.
