Description

Technical Field

[0001] The utility model belongs to the technical field of equipment management, and in particular relates to an environmental management system for an all-in-one inverter. Background Art

[0002] The all-in-one inverter-boost unit primarily utilizes a bidirectional inverter. Depending on the load, it steps down the high-voltage AC power from the grid and converts it to DC power for input into the battery compartment. Alternatively, it converts the DC power generated by the battery into AC power and boosts it for integration into the grid. It organically combines the functions of a transformer, energy storage system, and low-voltage power distribution system, resulting in a highly integrated, compact, and easy-to-install complete power distribution unit.

[0003] To accurately monitor the operating environment of the equipment within each compartment of an inverter-boost system, most existing inverter-boost systems are equipped with environmental monitoring systems. However, most systems only monitor the temperature and humidity of each compartment separately. However, since some inverter-boost systems operate in relatively high humidity environments with large temperature swings between day and night, these operating environments are extremely harsh and prone to condensation or icing. This can cause insulation defects and electrical hazards such as flashover and creepage in components, busbar cables, and other electrical equipment within the inverter-boost system. Furthermore, inverter-boost systems typically operate at full load during daytime hours when grid load is low, charging batteries for peak discharge. During full-load operation, inadequate heat dissipation can accelerate the aging of internal components and even cause fires, endangering equipment and personnel. Existing environmental monitoring systems for inverter-boost systems lack the ability to simultaneously monitor condensation on electrical equipment and the temperature of each compartment, nor do they have the ability to remove condensation, making it impossible to promptly eliminate condensation hazards, which in turn affects the normal operation of the inverter. Summary of the Invention

[0004] The purpose of this utility model is to provide an environmental management system for an all-in-one inverter to solve the problems in the prior art.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] An environmental management system for an all-in-one inverter includes a controller, a temperature and humidity sensor, a dew point sensor, a smoke sensor, a dehumidifier, an axial flow fan, a heater, and a power supply for the entire system. Each compartment in the all-in-one inverter is equipped with a temperature and humidity sensor, a dew point sensor, and a smoke sensor. The temperature and humidity sensor is mounted on a side wall of the compartment, the dew point sensor is mounted on the top of the compartment, and the smoke sensor is mounted on a ventilation louver provided on the compartment. The dehumidifier is mounted on the side wall of the compartment, and a water pipe is disposed at the bottom of the dehumidifier. The end of the water pipe, remote from the dehumidifier, is connected to a drain port provided on the housing of the all-in-one inverter. The axial flow fan is mounted on the side wall of the compartment and on the top of a low-voltage communication power cabinet provided in the all-in-one inverter. The heater is mounted on the side wall of the compartment.

[0007] The temperature and humidity sensor, dew point sensor and smoke sensor are all connected to the input end of the controller, and the dehumidifier, axial flow fan and heater are all connected to the output end of the controller.

[0008] A further improvement of the technical solution is that it also includes an amplifying circuit and an analog-to-digital conversion circuit, and the temperature and humidity sensor, the dew point sensor and the smoke sensor are all connected to the controller through the amplifying circuit and the analog-to-digital conversion circuit in sequence.

[0009] A further improvement of the technical solution is that the amplifier circuit includes a resistor R1, a resistor R2, a resistor R3, a capacitor C1, a capacitor C2, a resistor R4, an amplifier U1, a capacitor C3, a resistor R5, a resistor R6, a resistor R7 and an amplifier U2;

[0010] The temperature and humidity sensor, dew point sensor and smoke sensor are all connected to the first end of resistor R1, the second end of resistor R1 is connected to the first end of resistor R2, the first end of resistor R3, the first end of capacitor C1 and the first end of capacitor C2, the second end of resistor R3 is grounded, the second end of capacitor C1 is connected to the inverting input of amplifier U1 and the first end of resistor R4, the second end of resistor R4 is connected to the second end of capacitor C2, the non-inverting input of amplifier U1 is grounded through capacitor C3, resistor R5 and resistor R6 in parallel, the output of amplifier U1 is connected to the inverting input of amplifier U2 through resistor R7, the output of amplifier U1 is also connected to the second end of resistor R4, the non-inverting input of amplifier U2 is connected to the non-inverting input of amplifier U1, and the output of amplifier U2 is connected to the analog-to-digital conversion circuit.

[0011] A further improvement of the present technical solution is that the analog-to-digital conversion circuit includes an analog-to-digital conversion chip U3, the analog signal input pin of the analog-to-digital conversion chip U3 is connected to the output end of the amplifier U2, and the digital signal output pin of the analog-to-digital conversion chip U3 is connected to the controller.

[0012] A further improvement of this technical solution is that the analog-to-digital conversion chip U3 adopts an analog-to-digital conversion chip of model ADC0832.

[0013] A further improvement of the technical solution is that it further comprises a remote monitoring terminal and an RS485 communication module, and the controller is connected to the remote monitoring terminal via the RS485 communication module.

[0014] The beneficial effect of the present invention is that, in the environmental management system of the inverter-integrated machine, configuring components such as a dew point sensor will bring a series of beneficial effects, which not only solve the technical problems mentioned above, but also significantly improve the performance and reliability of the system.

[0015] First, installing a dew point sensor allows for real-time monitoring of the dew point temperature within the compartment, accurately determining whether condensation risk exists. Condensation is highly detrimental to electrical equipment, as it can cause water droplets to form inside the equipment, leading to electrical faults such as short circuits and corrosion. Real-time monitoring by the dew point sensor allows the system to take appropriate measures before condensation risk occurs, such as activating the dehumidifier and adjusting the operation of the axial flow fan, effectively preventing condensation and ensuring normal equipment operation.

[0016] Secondly, the dew point sensor can work in conjunction with other sensors (such as temperature and humidity sensors and smoke sensors) to form a more comprehensive and accurate environmental monitoring network. The system can comprehensively judge the environmental conditions within the compartment based on the data from each sensor and adjust the control strategy accordingly to achieve more precise environmental control. This not only improves system efficiency, but also reduces energy consumption and extends the life of the equipment.

[0017] In addition, the utility model has a reliable design principle, a simple structure and a very broad application prospect.

[0018] It can be seen that compared with the prior art, the present invention has outstanding substantial features and significant progress, and the beneficial effects of its implementation are also obvious. BRIEF DESCRIPTION OF THE DRAWINGS
