Power supply control cabinet system and operation method thereof

Abstract

The invention provides a power supply control cabinet system and an operation method of the power supply control cabinet system. The power supply control cabinet system comprises a central processing unit module, a network module, a signal collection module, a displayer, an input terminal, a power input module, a power output module and a power supply switching module, wherein the power input module comprises a plurality of input channels, the power output module comprises a direct-current output module and an alternating-current output module, and the power supply switching module is connected with the power input module and switches a corresponding power supply loop into a system circuit according to user hand-operated selection or system presetting or a signal analysis result. By means of real-time monitoring of a central processing unit and a signal collection device, the defect that a traditional control cabinet is low in control accuracy is overcome in terms of input control and output control of power supplies, the situation that the over-current and the under voltage happen to circuit and other situations can be timely prevented, safety performance of a circuit system is effectively ensured, and meanwhile power supply safety and power supply quality of the system is ensured by setting multiple modes to conduct selection and switching on the power supplies.

Description

technical field [0001] The invention belongs to the technical field of electric power system automation control, and in particular relates to a power supply control cabinet system and an operation method thereof. Background technique [0002] Traditional power supply control cabinets are composed of air switches, leakage protectors and other auxiliary materials. After assembly, electricians need a lot of wiring and handwriting with corresponding stickers to mark the definition of an air switch representative (such as lighting, air conditioning, wall sockets, etc.) ), this integration method determines its large size, complicated wiring, high error rate, and low work efficiency during installation. If it is put into use, if it is operated frequently, or the label is stained or lost, it will bring many complicated and repetitive maintenance. labor.

[0002] Traditional power supply control cabinets are composed of air switches, leakage protectors and other auxiliary materials. After assembly, electricians need a lot of wiring and handwriting with corresponding stickers to mark the definition of an air switch representative (such as lighting, air conditioning, wall sockets, etc.) ), this integration method determines its large size, complicated wiring, high error rate, and low work efficiency during installation. If it is put into use, if it is operated frequently, or the label is stained or lost, it will bring many complicated and repetitive maintenance. labor

Moreover, due to its production mode, the air switch determines that the current value it can pass is fixed, but in fact, the operating current of the electrical equipment is often far less than the rated current that the air switch can pass, so the air switch often can only play a role. Control the function of on-off, but cannot realize the precise control of the current, so the damage of the electrical equipment due to factors such as undervoltage and overcurrent cannot be effectively avoided only by using the air switch

Especially in the case of complex power consumption environments, such as computer rooms, reference rooms, emergency command centers, monitoring centers, special vehicles, special vehicles, yachts, ships, small aircraft, etc., traditional power supply control cabinets often suffer from power line switching. resulting in damage to valuable equipment

If the utility power encounters a power outage and needs to be switched to a generator power supply or UPS power supply, because the circuit power is limited, it is easy to cause a power outage of the entire system or equipment damage, and even cause immeasurable losses
