Description

Technical Field

[0001] The present invention relates to the field of electrolytic single cell fault indication. More specifically, the present invention relates to an electrolytic single cell fault indication system. Background Art

[0002] With the increasing market and user demand for higher production capacity of electrolyzers, in order to improve the monomer production capacity of electrolyzers, the volume of electrolyzers gradually increases and the number of electrolytic single cells increases. While the safe operation of electrolyzers faces higher requirements and challenges, more refined and efficient electrolytic single cell monitoring technologies are also needed. The traditional means of only monitoring the macroscopic parameters of the entire electrolyzer can no longer meet the requirements by far. During the operation of the electrolyzer, each electrolytic single cell may fail or malfunction. As the number of electrolytic cells increases, there are now more than three hundred electrolytic single cells, and even more in the future. The probability of risk occurring in an electrolyzer containing such a large number of electrolytic single cells will increase significantly. It is difficult to quickly and accurately locate the fault after an electrolytic single cell fails, which greatly increases the maintenance difficulty, thus affecting the working efficiency of the entire electrolyzer and even the entire electrolytic water hydrogen production system. Summary of the Invention

[0003] To achieve these and other advantages in accordance with the present invention, a preferred embodiment of the present invention provides an electrolytic single cell fault indication system. There are a number of electrolytic cells in the electrolyzer, and one electrolytic single cell is arranged in each electrolytic cell. The electrolytic single cell fault indication system includes:

[0004] A number of voltage sensors, each of which is correspondingly arranged in each electrolytic cell for real-time monitoring of the voltage in the electrolytic cell;

[0005] A controller, which is electrically connected to the voltage sensors. The controller receives the voltage signal values sent by each voltage sensor, forms a voltage fluctuation curve, and compares the voltage fluctuation curve with a preset normal working voltage fluctuation curve to determine whether the difference between the two is within a preset range;

[0006] A number of indicator lights, which are controlled and connected to the controller. The controller issues an indicator light color change signal according to the difference between the voltage fluctuation curve and the preset normal working voltage fluctuation curve. The indicator lights display corresponding colors according to the indicator light signals, and each indicator light corresponds to an electrolytic single cell.

[0007] According to a preferred embodiment of the present invention, the controller receives the voltage signal value emitted by each of the voltage sensors to form a voltage fluctuation curve, and compares the voltage fluctuation curve with the normal working voltage fluctuation curve to determine whether the difference between the two is within a preset range. If the difference is not within the preset range, the controller sends an indication signal that the indicator light turns red; if the difference is within the preset range, the controller sends an indication signal that the indicator light turns green.

[0008] According to a preferred embodiment of the present invention, the controller is a PLC controller.

[0009] According to a preferred embodiment of the present invention, it also includes a signal transmission positioning faulty plate single chip, which is electrically connected to the controller. When the controller sends an indication signal that the indicator light turns red, the signal transmission positioning faulty plate single chip determines the specific position of the abnormal electrolytic single chip based on the indication signal.

[0010] According to a preferred embodiment of the present invention, the voltage sensor is detachably mounted.

[0011] According to a preferred embodiment of the present invention, each of the electrolytic monolithic sheets corresponds to the indicator light one by one, and the indicator light is fixed on the corresponding electrolytic monolithic sheet.

[0012] The present invention has at least the following beneficial effects:

[0013] (1) Rapidly and efficiently respond to the real-time status of the faulty single chip, making it convenient to detect the working status of the electrolytic cell;

[0014] (2) When an abnormality occurs in the electrolytic cell, the fault indication system can immediately issue an alarm reminder, saving the preparation time for the maintenance of the electrolytic cell, greatly reducing labor costs and improving the operating efficiency of the electrolytic cell;

[0015] (3) The fault indication system is adaptable to electrolytic cells of various production capacities, is easy to install and disassemble, and can be reused, thus reducing equipment investment costs.

[0016] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

These are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0021] It can be understood that the term "a" should be understood as "at least one" or "one or more".

[0022] As Figure 1 shown, a preferred embodiment of the present invention provides an electrolytic single-chip fault indication system. There are several electrolytic chambers 1 in the electrolytic cell, and one electrolytic single chip 2 is arranged in each electrolytic chamber. The electrolytic single-chip fault indication system includes:

[0023] Several voltage sensors, and one of the voltage sensors is respectively arranged corresponding to each electrolytic chamber for real-time monitoring of the voltage in the electrolytic chamber;

[0024] A controller, which is electrically connected to the voltage sensors. The controller receives the voltage signal values sent by each of the voltage sensors, forms a voltage fluctuation curve, and compares the voltage fluctuation curve with a preset normal working voltage fluctuation curve to determine whether the difference between the two is within a preset range;

[0025] Several indicator lights 3, which are controlled and connected to the controller. The controller issues an indicator light color change signal according to the difference between the voltage fluctuation curve and the preset normal working voltage fluctuation curve, and the indicator lights display corresponding colors according to the indicator light signal. Each indicator light corresponds to an electrolytic single chip.

[0026] Specifically, each of the electrolytic single chips corresponds one-to-one with the indicator lights, and the indicator lights are fixed on the corresponding electrolytic single chips

[0027] In the above technical solution, by monitoring the voltage fluctuation of the electrolysis cell in real time and comparing it with the normal voltage fluctuation range, the working state of the electrolysis single sheet in the electrolysis cell is judged. If the difference between the two is within the preset range, it indicates that the working state of the electrolysis single sheet is normal. If the difference between the two is not within the preset range, it indicates that the working state of the electrolysis single sheet is abnormal and in an abnormal state.

[0028] According to a preferred embodiment of the present invention, the controller receives the voltage signal values sent by each of the voltage sensors, forms a voltage fluctuation curve, and compares the voltage fluctuation curve with the normal working voltage fluctuation curve to judge whether the difference between the two is within the preset range. If the difference is not within the preset range, the controller sends an indication signal for the indicator light to turn red. If the difference is within the preset range, the controller sends an indication signal for the indicator light to turn green.

[0029] For the convenience of the staff to observe, when the difference between the two is within the preset range for a certain electrolysis single sheet, the indicator light corresponding to this electrolysis single sheet will be green, indicating normal. This color is not limited to green and can also be other colors.

[0030] For the convenience of the staff to observe, when the difference between the two is not within the preset range for a certain electrolysis single sheet, the indicator light corresponding to this electrolysis single sheet will be red, indicating abnormality, and reminding the staff to carry out subsequent maintenance work. This color is not limited to red and can also be other colors.

[0031] According to a preferred embodiment of the present invention, the controller is a PLC controller. A PLC controller is a digital operation controller with a microprocessor for automatic control, and it can load control instructions into the memory for storage and execution at any time.

[0032] According to a preferred embodiment of the present invention, in order to facilitate the staff to quickly find the specific location of the electrolysis single sheet with an abnormality after seeing the indicator light turn red, the following technical solution is proposed.

[0033] Specifically, an electrolysis single sheet fault indication system further includes a signal transmission and positioning fault electrode plate single sheet, which is electrically connected to the controller. When the controller sends an indication signal for the indicator light to turn red, the signal transmission and positioning fault electrode plate single sheet determines the specific location of the electrolysis single sheet with an abnormality according to this indication signal. In this way, it can help the staff quickly find the location of the electrolysis single sheet with an abnormality, greatly improve the work efficiency, reduce the labor cost to a large extent, and improve the working operation efficiency of the electrolytic cell.

[0034] According to a preferred embodiment of the present invention, the voltage sensor is detachably installed and adapted to electrolytic cells with various production capacities, facilitating installation and disassembly, capable of being reused, and reducing the equipment investment cost.

[0035] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those skilled in the art, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples herein.
