[0002] Gas stations are public places with high flammability, explosiveness, and frequent traffic. To ensure the electrical safety of staff and customers, power distribution in gas stations is done in distribution cabinets.

[0003] Currently, the main power distribution structure in gas station electrical cabinets is a dual-power supply, with each level switch controlled by a single circuit breaker. From a cost control perspective, power supply and de-energization operations require on-duty personnel to manually operate the circuit breakers after opening the distribution cabinet. This is inefficient in daily maintenance and hinders efforts to reduce energy consumption per workstation and achieve effective energy conservation. From an electrical safety perspective, abnormal cable temperatures, short circuits, overloads, or leakage can all cause electrical fires. In emergencies such as fires, on-duty personnel must discover the danger before cutting off the power, highlighting the urgent need for improvement in both safety and timeliness.

Attached Figure Description

[0027] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof.

[0028] In the attached diagram:

[0029] Figure 1 This is a schematic diagram showing the connection relationship of each component in Embodiment 1 of this utility model. Detailed Implementation

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] Example 1: A gas station power distribution cabinet

[0032] like Figure 1 As shown, this embodiment includes a cabinet and a cabinet door. The cabinet also includes a dual-power transfer switch, a four-phase circuit breaker, a circuit breaker matched to the number of electrical appliances and capable of detecting the current, voltage, and power consumption of the appliances, a temperature sensor monitoring the temperature of the electrical appliance cables, a monitoring and control module controlling the opening and closing of the circuit breaker and the four-phase circuit breaker, a voltage detection module monitoring the stability of the voltage at the four-phase circuit breaker, a surge protector, a display interface, and an alarm device. Here, "matching" means that there is a one-to-one correspondence between the electrical appliances and the circuit breakers. The electrical appliances include: fuel dispensers, a tertiary recycling system, a boiler room, a neutral pipe system, a convenience store, canopy lights, a station building, and a car wash.

[0033] The dual-power transfer switch connects to both mains power and generator power, and is electrically connected to the four-phase circuit breaker as the power supplier. Electrical appliances are connected in series with their corresponding circuit breakers, then in parallel, and finally sequentially connected to the four-phase circuit breaker to form a circuit.

[0034] The surge protector is located between the dual power transfer switch and the four-phase circuit breaker to protect the circuit.

[0035] The voltage detection module's detection point is located between the dual-power transfer switch and the four-phase circuit breaker. It is used to detect whether the voltage at the four-phase circuit breaker is abnormal. The signal output terminal of the voltage detection module is connected to the signal input terminal of the four-phase circuit breaker. If the voltage detection module does not detect any abnormality, the four-phase circuit breaker will close normally; if the voltage detection module detects an abnormal voltage, it will control the four-phase circuit breaker to open.

[0036] The signal output terminal of the temperature sensor is connected to the signal input terminal of the monitoring and control module. There is two-way signal communication between the circuit breaker and the monitoring and control module. The signal input terminal of the four-phase circuit breaker is connected to the signal output terminal of the monitoring and control module.

[0037] The signal output terminals of the monitoring and control module are connected to the signal input terminals of the display interface and the alarm device, respectively. To achieve remote monitoring and control, the monitoring and control module establishes two-way signal communication with the user terminal via the Internet of Things (IoT).

[0038] In this embodiment, the user first selects between mains power and generator power based on the power supply situation. If the mains power is normal, the dual power switch uses mains power; if the mains power fails and a generator is needed, the dual power switch uses generator power.

[0039] After the power supply is selected, it reaches the four-phase circuit breaker. The voltage detection module detects the voltage at the four-phase circuit breaker. If the voltage is normal, the four-phase circuit breaker closes normally; if the voltage is abnormal, the four-phase circuit breaker opens. When the voltage is normal, the power supply passes through each circuit breaker to each electrical facility. The circuit breaker detects the voltage, current, and power consumption of the electrical facility and transmits the information to the monitoring and control module. Temperature sensors also transmit the cable temperature information of the electrical facility to the monitoring and control module. After receiving the voltage, current, power consumption, and cable temperature information of the electrical facility, the monitoring and control module displays the information on the display interface and compares it with preset values. If the voltage or current is abnormal, it controls the corresponding circuit breaker to open and sends an alarm signal to the alarm device. If the power consumption exceeds the set value, the energy-saving mode is activated, automatically shutting off the circuit breakers of the corresponding electrical facilities at a set time, such as automatically turning off the canopy lights during the day and automatically turning off the power to the car wash at night. If the cable temperature is abnormal, it controls the four-phase circuit breaker to open and sends an alarm signal to the alarm device.

[0040] The information received by the monitoring and control module can also be transmitted to the user's terminal (mobile phone, PC or tablet) via the Internet of Things. The user can see the voltage, current, power consumption and cable temperature information of the electrical facilities on the terminal, and control the circuit breakers at the corresponding electrical facilities.

[0041] In summary, this embodiment can monitor and control all electrical facilities in a gas station throughout the entire process, saving energy and reducing costs. It can also promptly detect safety issues in electrical circuits and equipment, ensuring the electrical safety of the gas station.
