Description

Technical Field

[0001] This utility model relates to the field of power distribution system technology, specifically to an intelligent alarm power distribution system with remote control function. Background Technology

[0002] As the core infrastructure of various power consumption scenarios (especially special scenarios such as mobile hospitals where the stability and safety of power supply are highly critical), the power distribution system's operational performance directly affects the safety of operators and the stable operation of electrical equipment. With the development of technology, the types of electrical equipment in scenarios such as mobile hospitals are constantly increasing (such as transmitters, display and control equipment, air conditioning systems, etc.), which places higher demands on the functional integrity, intelligence level, and safety protection capabilities of the power distribution system.

[0003] However, existing power distribution systems have significant shortcomings in practical applications, making it difficult to meet current usage needs: First, they lack a comprehensive intelligent alarm mechanism for multiple faults such as leakage, over / under voltage, and overcurrent. They cannot collect power parameters in real time to predict faults, nor can they differentiate fault types through differentiated early warnings. Fault location is difficult, and response is slow, which can easily lead to electric shock or equipment damage, resulting in insufficient safety. Second, they rely on local operation and lack remote control capabilities, making operation and maintenance difficult and inefficient. Furthermore, they do not achieve independent power supply control for equipment, and a single fault can easily affect the entire system. They cannot meet the needs of scenarios such as makeshift hospitals for intelligent and efficient power distribution systems. The demand for power distribution systems with such functions is becoming increasingly urgent with technological development. Utility Model Content

[0016] Please see Figure 1-10 An intelligent alarm power distribution system with remote control function includes electrical equipment, and further includes a power supply input unit 1, a power conversion and communication unit 2, a power monitoring unit 3, an intelligent alarm unit 4, a multi-load protection and control unit 5, an overcurrent protection unit 6, and an over / undervoltage protection unit 7. The power conversion and communication unit 2 is electrically connected to the power supply input unit 1, and receives the electrical energy output from the power supply input unit 1 and performs conversion and communication. The power monitoring unit 3 is electrically connected to the output line of the power supply input unit 1, and the output line of the power monitoring unit 3 is electrically connected to the multi-load protection and control unit 5. The system collects power parameters from the output side of the power input unit 1 and the multi-load protection and control unit 5; the intelligent alarm unit 4 is electrically connected to the power input unit 1; the multi-load protection and control unit 5 is connected to the load of the electrical equipment; the overcurrent protection unit 6 is electrically connected to the power monitoring unit 3; the over- and under-voltage protection unit 7 is electrically connected to the output side line of the power input unit 1; the power input unit 1 includes external power interfaces (XT-1, XT-2, XT-3, XT-4) and a residual current circuit breaker (QF1), and the external power interfaces (XT-1, XT-2, XT-3, XT-4) are all electrically connected to the residual current circuit breaker (QF1).

[0017] This application further proposes that the power conversion and communication unit 2 includes a switching power supply (AC-DC conversion) and an RS485 to Ethernet serial server. The input terminal of the switching power supply (AC-DC conversion) is electrically connected to the leakage current protection circuit breaker (QF1), and the output terminal of the switching power supply (AC-DC conversion) is electrically connected to the RS485 to Ethernet serial server.

[0018] Specifically, the input terminal of the switching power supply (AC-DC converter) is directly connected to the residual current circuit breaker (QF1), which can stably receive AC power from the system and convert it into a suitable DC power, providing a safe and matched power supply for the RS485 to Ethernet serial port server. This avoids communication equipment failure or damage due to incompatible power types, ensuring the continuous and stable operation of the communication module. The RS485 to Ethernet serial port server starts up with the converted DC power supply, enabling efficient conversion between internal serial port signals and external Ethernet signals in the power distribution system. It builds a data transmission bridge between the system and remote terminals (such as host computers), supporting remote terminals to send control commands to the system (such as remote closing / opening), breaking the local operation limitations of traditional power distribution systems.

[0019] This application further proposes that the over / under voltage protection unit 7 includes a three-phase over / under voltage protection relay 12 and a contactor (F1). The three-phase over / under voltage protection relay 12 is electrically connected to the output side line of the residual current circuit breaker (QF1), and the output terminal of the three-phase over / under voltage protection relay 12 is electrically connected to the contactor (F1).

[0020] Specifically, the three-phase over / under voltage protection relay 12 is connected to the output line of the residual current circuit breaker (QF1), which can monitor the dynamic changes of the three-phase voltage in the system in real time and detect abnormalities such as overvoltage, undervoltage, and phase sequence errors. When the voltage exceeds the normal range (e.g., exceeds ±20%) or the phase sequence is incorrect, the relay can immediately trigger the contactor (F1) connected to it to quickly cut off the power supply to the subsequent circuit. This can not only avoid irreversible damage such as insulation damage and performance degradation to electrical equipment (e.g., transmitters, display and control equipment) caused by abnormal voltage, but also prevent equipment failure caused by the reverse operation of motor loads (e.g., air conditioners, exhaust equipment) due to phase sequence errors. At the same time, compared with traditional passive protection, the active monitoring and fast response characteristics of this unit significantly shorten the time from voltage abnormality to protection action, providing more timely and reliable voltage protection for the system and equipment, and further ensuring the stable operation and service life of electrical equipment in the shelter.

[0021] This application further proposes that it also includes a power indicator unit 8; the power indicator unit includes power indicator lights (HL1, HL2, HL3), and the power indicator lights (HL1, HL2, HL3) are electrically connected to the output line of the residual current circuit breaker (QF1).

[0022] Specifically, the power indicator lights (HL1, HL2, HL3) are directly connected to the output line of the residual current circuit breaker (QF1) and can reflect the on / off status of the core power supply circuit in real time. When the residual current circuit breaker (QF1) is normally closed to supply power, the indicator lights will light up, and the operator can visually confirm that the system is in a power-on ready state through the lights. If the residual current circuit breaker (QF1) trips and cuts off the power supply due to faults such as leakage or overload, the indicator lights will turn off simultaneously, which can quickly indicate the power supply interruption and avoid misoperation due to the inability to judge the power supply status.

[0023] This application further proposes that the intelligent alarm unit 4 includes a module power input interface (XP1), a buzzer, a contactor contact (XP3), a ground light (blue), a leakage current light (red), an AC light (green), a stop bell (XP102), and an integrated structure for measuring ground and vehicle ground (XP101), an alarm ground (XT-22), and XT-PE; the module power input interface (XP1) is electrically connected to the output side of the external power interface (XT-1, XT-2, XT-3, XT-4); the integrated structure for measuring ground and vehicle ground (XP101) is electrically connected to the alarm ground (XT-22) and XT-PE through two orange wires and two brown wires, respectively.

[0024] Specifically, through the integrated structure of measurement ground and vehicle ground (XP101), reliable grounding is achieved by using dual orange wires and dual brown wires to connect to the alarm ground (XT-22) and XT-PE respectively, thus constructing a multi-layer grounding protection system. This effectively reduces the risk of leakage voltage and leakage current caused by poor grounding, laying a solid foundation for the safe operation of the system. The module power input interface (XP1) is directly connected to the external power output line to ensure a continuous and stable power supply to the alarm module. When the system experiences faults such as leakage or grounding abnormalities, the red leakage light and blue ground wire light can quickly distinguish the fault type through differentiated colors. Combined with the alarm sound emitted by the buzzer (linked with the contactor contact XP3), a dual warning is formed, allowing operators to detect the fault and locate the problem direction as soon as possible. At the same time, the green AC light can intuitively reflect the basic power supply status of the circuit, and the silencer (XP102) makes it convenient to turn off the alarm sound during fault handling to avoid interference.

[0025] This application further proposes that the power monitoring unit 3 includes a liquid crystal three-phase voltmeter 9 and a liquid crystal three-phase ammeter 10. The liquid crystal three-phase voltmeter 9 is electrically connected to the output side line of the leakage current protection circuit breaker (QF1), and the liquid crystal three-phase ammeter 10 is electrically connected to the liquid crystal three-phase voltmeter 9 and to the input side line of the multi-load protection and control unit 5.

[0026] Specifically, the LCD three-phase voltmeter 9 is directly connected to the output line of the residual current circuit breaker (QF1), which can capture the dynamic changes of the total input voltage of the system in real time and detect abnormalities such as voltage fluctuations and imbalances in a timely manner; the LCD three-phase ammeter 10 is linked with the voltmeter 9 to form a data association, and is also connected to the input line of the multi-load protection and control unit 5, which can accurately collect the current parameters of each load, providing a basis for judging the overall power load and branch current distribution.

[0027] This application further proposes that the multi-load protection and control unit 5 includes multiple air circuit breakers (QF2, QF3, QF4, QF5, QF6, QF7, QF8), which are respectively connected to the loads of electrical equipment (transmitter, air conditioner 1, air conditioner 2, lighting, exhaust, wall socket, display control, signal generation) and are electrically connected to the output side of the LCD three-phase ammeter 10.

[0028] Among them, QF5 is a 6A air circuit breaker, which controls the power supply for lighting and ventilation; QF6 is a 16A air circuit breaker, which controls the power supply for wall sockets; QF7 is a 16A air circuit breaker, which controls the power supply for display and control; and QF8 is a 10ARS485 intelligent air circuit breaker.

[0029] Specifically, multiple air circuit breakers (QF2, QF3, QF4, QF5, QF6, QF7, QF8) are connected to the transmitter, air conditioner 1, air conditioner 2, lighting, ventilation, wall sockets, display and control, signal generation, and other electrical equipment, respectively. They are also directly connected to the output circuit of the LCD three-phase ammeter 10. This allows for matching appropriate circuit breakers to the power requirements of different equipment (e.g., high current for the transmitter, low current for lighting), achieving independent on / off control of each load and preventing a single equipment failure from affecting the power supply of other branches. This ensures the continuous operation of critical equipment within the shelter; it also leverages the overload and short-circuit protection functions of the air circuit breaker, combined with real-time current monitoring by the LCD three-phase ammeter 10, to quickly disconnect the circuit when abnormal current occurs in the corresponding equipment, effectively preventing equipment damage due to overload or short circuit; at the same time, when a branch circuit fails, operators can quickly locate the faulty equipment through the status of the corresponding circuit breaker, without needing to shut down the entire system for troubleshooting. After troubleshooting, power supply can be restored simply by resetting the corresponding circuit breaker, significantly improving operation and maintenance efficiency and reducing the risk of system downtime.

[0030] This application further proposes that the overcurrent protection unit 6 includes multiple current monitoring relays 11 and multiple contactors (F2, F3, F4). The multiple current monitoring relays 11 are electrically connected to the liquid crystal three-phase ammeter 10 and are respectively electrically connected to the multiple contactors (F2, F3, F4).

[0031] Specifically, the overcurrent protection unit 6, through the coordinated operation of multiple current monitoring relays 11 and the LCD three-phase ammeter 10, can monitor the current status of multiple load circuits in real time. When an overcurrent occurs in any circuit, the corresponding current monitoring relay 11 can quickly trigger the contactor (F2, F3, F4) to operate and accurately cut off the power supply to the faulty branch.

[0032] Working process and principle: The external power supply is connected through the external power interface (XT-1, XT-2, XT-3, XT-4), and is initially protected by the leakage current protection circuit breaker (QF1). At the same time, the power indicator lights (HL1, HL2, HL3) light up synchronously to intuitively reflect the power-on status of the system. After power-on, the three-phase over / under voltage protection relay (12) monitors the three-phase voltage on the output side of the leakage current protection circuit breaker (QF1) in real time. If an error in phase sequence or a voltage exceeding ±20% is detected, an over / under voltage audible and visual alarm is immediately issued and the contactor (F1) is controlled to disconnect, cutting off the power supply to the subsequent circuit to avoid equipment damage. The integrated structure of the measurement ground and the vehicle ground (XP101) is reliably connected to the alarm ground (XT-22) and XT-PE through double orange wires and double brown wires, respectively. When the leakage voltage between the vehicle ground and the detection ground is greater than AC36V ( When the allowable error is ±4V, the AC input power supply is cut off to achieve leakage voltage protection. If the grounding resistance between the two is greater than 50kΩ (allowable error ±5kΩ), the grounding alarm fault indicator flashes and the alarm buzzer sounds continuously. At this time, the distribution box can work normally. The distribution box also performs leakage current detection on the AC input. When the effective leakage current is greater than or equal to 300mA (allowable error ±5mA), the AC input power supply is cut off after 3 seconds to achieve leakage current protection. Both leakage current and leakage voltage faults will cause the corresponding fault indicator to flash and the alarm buzzer to sound intermittently. Subsequently, the power conversion and communication unit 2 is started. The switching power supply (AC-DC conversion) converts the AC power output of QF1 into DC power to power the RS485 to Ethernet serial port server. The RS485 to Ethernet serial port server realizes the communication conversion between serial port and Ethernet, and builds a data transmission bridge between the system and the remote terminal. The power monitoring unit 3 operates synchronously. The LCD three-phase voltmeter 9 collects the total line voltage parameters in real time, and the LCD three-phase ammeter 10 accurately monitors the current data on the input side of the multi-load protection and control unit 5 to realize the visual monitoring of power consumption status. In the multi-load protection and control unit 5, air circuit breakers of different specifications, such as QF2 to QF8, are connected to various electrical equipment including transmitters, air conditioners 1 and 2, lighting, exhaust fans, wall sockets, displays, and signal generators. Independent on / off control enables hierarchical load management and allows for remote closing and opening operations. When any AC output experiences an overcurrent, the corresponding AC output is cut off, the overcurrent fault indicator flashes, and the alarm buzzer sounds intermittently, without affecting power supply to other branches. Normal operation can be manually restored after the fault is cleared. After clearing various faults, the distribution box can be manually restored to normal operation, significantly improving system maintenance efficiency and electrical safety.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
