A method for operating a power control cabinet system

Abstract

A power control cabinet system and its operating method, the power control cabinet system includes: a central processing unit module, a network module, a signal acquisition module, a display and an input terminal, a power input / output module and a power switching module, and the power input module includes Multiple input channels, the power output module includes a DC output module and an AC output module, the power switching module is connected to the power input module, and switches the corresponding power circuit to the system circuit according to the user's manual selection, system preset or signal analysis results . Through the real-time monitoring of the central processor and the signal acquisition device, the present invention overcomes the defect of low control precision of the traditional control cabinet in terms of power supply input control and output control, and can avoid the occurrence of circuit overcurrent and undervoltage in time, effectively ensuring The safety performance of the circuit system is ensured, and at the same time, the power supply safety and power supply quality of the system are guaranteed by setting multiple modes to select and switch the power supply.

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 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 frequently operated, 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 cur...

[0002] Traditional power 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 frequently operated, 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
