Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling technology for SVG devices, specifically to a coolant release device and an SVG system. Background Technology
[0002] SVG (Static Var Generator) is a dynamic reactive power compensation device based on a voltage source converter. It can quickly provide or absorb reactive power, and its main function is to improve power quality, voltage stability, and the reactive power control capability of wind farms. The power grid has strict requirements on the SVG's operational rate and regulation qualification rate at each wind farm. When an SVG system fails, quickly resolving the fault and restoring its function is particularly important. For example, when an SVG system power module fails, replacing the power module requires removing the coolant. Currently, the common method for removing coolant is by gravity discharge, but this process is time-consuming. This step takes up a significant portion of the overall fault handling process, hindering the timely elimination of the SVG system fault. Utility Model Content
[0003] The technical problem to be solved by this utility model is to shorten the fault handling time and improve the fault handling efficiency.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A coolant release device includes: a coolant tank, an outlet pipe, a return pipe, and a power module. The outlet of the coolant tank is connected to one end of the outlet pipe, the other end of the outlet pipe is connected to the inlet of the power module, the drain of the power module is connected to one end of the return pipe, the other end of the return pipe is connected to the return port of the coolant tank, and a quick release component is also provided on the return pipe.
[0005] The beneficial effects of this invention are as follows: the coolant in the coolant tank reaches the power module through the outlet pipe, thereby carrying away the heat generated by the power module. The coolant flowing through the power module flows back into the coolant tank through the return pipe. When the power module fails, it is necessary to drain the coolant from the power module and replace the power module. By setting up a quick-release component, the coolant in the power module can be released quickly, thereby reducing the time required for troubleshooting.
[0006] Based on the above technical solution, the present invention can be further improved as follows.
[0007] Furthermore, the rapid release assembly includes a pump and a branch pipeline, with both ends of the branch pipeline connected to the return water pipeline, and the pump disposed on the branch pipeline.
[0008] The beneficial effect of adopting the above-mentioned further solution is that by setting up pumps and branch pipelines, when the power module fails, the pumps can be used to force the coolant to be pumped out. Compared with simply relying on gravity to drain the coolant, the coolant in the power module can be emptied more quickly, thereby shortening the troubleshooting time.
[0009] Furthermore, the quick release device also includes a second valve, which is disposed at one end of the branch pipe near the power module and at the connection between the return water pipe and the branch pipe.
[0010] The beneficial effect of adopting the above-mentioned further solution is that by setting a second valve at one end of the branch pipeline near the power module, the second valve can be opened when the power module fails, so that the branch pipeline and the power module are connected, and the coolant in the power module can be drained quickly.
[0011] Furthermore, the pump is model LPm125.
[0012] The advantages of adopting the above-mentioned further solution are: this model of pump has the characteristics of high flow rate and corrosion resistance, is easy to use, and is suitable for coolant media, which can ensure the rapid emptying of coolant in the power module.
[0013] Furthermore, the device also includes a heat dissipation device. The water outlet pipe includes a first water outlet pipe and a second water outlet pipe. One end of the first water outlet pipe is connected to the outlet of the coolant tank, and the other end of the first water outlet pipe is connected to the coolant inlet of the heat dissipation device. One end of the second water outlet pipe is connected to the coolant outlet of the heat dissipation device, and the other end of the second water outlet pipe is connected to the water inlet of the power module.
[0014] The beneficial effects of adopting the above-mentioned further solution are: by setting up a heat dissipation device, the coolant is cooled down, ensuring that the coolant effectively dissipates heat from the power module, improving cooling efficiency, and ensuring the normal and stable operation of the equipment.
[0015] Furthermore, a pressure-stabilizing pump is installed on the first section of the water outlet pipeline.
[0016] The beneficial effects of adopting the above-mentioned further solution are: by setting a pressure stabilizing pump on the first section of the water outlet pipeline, the coolant is stably delivered to the heat dissipation device, thereby cooling the coolant and ensuring that the coolant continuously circulates to cool and dissipate heat from the power module, ensuring the stable operation of the equipment. At the same time, the coolant is recycled, effectively saving resources.
[0017] Furthermore, a temperature sensor, a pressure gauge, and a flow meter are also installed on the first section of the outlet pipe between the coolant tank and the pressure stabilizing pump.
[0018] The beneficial effect of adopting the above-mentioned further solution is that by installing temperature sensors, pressure gauges and flow meters on the first section of the water outlet pipeline, multiple parameters can be monitored and controlled within a safe operating range, thereby improving system safety.
[0019] Furthermore, a first valve is installed on the second section of the water outlet pipe.
[0020] The beneficial effect of adopting the above-mentioned further solution is that by installing a first valve on the second water outlet pipe, when the power module fails, the first valve can be closed immediately to stop the supply of coolant to the power module, which facilitates the rapid start of the discharge of coolant from the power module.
[0021] Furthermore, the return water pipe and the coolant tank are located below the power module.
[0022] The beneficial effects of adopting the above-mentioned further solution are: by setting the return water pipe and coolant tank below the power module, the effective circulation of coolant is ensured, and when the power module fails, the coolant in the power module can still be drained by gravity, further shortening the troubleshooting time.
[0023] This invention also provides an SVG system, including the aforementioned coolant release device.
[0024] The beneficial effects are: by setting up a coolant release device, the stable operation of the system is ensured, and when the power module fails, the coolant in the power module can be quickly drained and replaced, shortening the fault handling time, improving the fault handling efficiency, thereby improving the qualification rate of SVG system regulation and ensuring the commissioning rate of SVG system.

[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0030] like Figures 1-2 As shown, this embodiment provides a coolant release device, including: a coolant tank 10, an outlet pipe 20, a return pipe 30, and a power module 40. The outlet of the coolant tank 10 is connected to one end of the outlet pipe 20, the other end of the outlet pipe 20 is connected to the inlet of the power module 40, the drain of the power module 40 is connected to one end of the return pipe 30, and the other end of the return pipe 30 is connected to the return port of the coolant tank 10. A quick release component is also provided on the return pipe 30.
[0031] The coolant in the coolant tank 10 reaches the power module 40 through the outlet pipe 20, thereby carrying away the heat generated by the power module 40. The coolant flowing through the power module 40 flows back into the coolant tank 10 through the return pipe 30. When the power module 40 fails, the coolant in the power module 40 needs to be drained and the power module 40 needs to be replaced. By setting up a quick-release component, the coolant in the power module 40 can be released quickly, thereby reducing the time required for troubleshooting.
[0032] It should be noted that the power module 40 is an electronic device in the system. The coolant pipeline is connected to it. When the coolant flows through the pipeline connected to the power module 40, it carries away the heat, thereby cooling the power module 40 and ensuring the stable operation of the equipment.
[0033] Based on the above technical solution, the rapid release component includes a pump 50 and a branch pipe 60, with both ends of the branch pipe 60 connected to the return water pipe 30, and the pump 50 disposed on the branch pipe 60.
[0034] By setting up pump 50 and branch pipe 60, when the power module 40 fails, the pump 50 can be used to force the coolant to be pumped out. Compared with simply relying on gravity to drain the coolant, the coolant in the power module 40 can be emptied faster, thereby shortening the troubleshooting time.
[0035] Optionally, the pump 50 can be connected to the return water line 30 via a hose.
[0036] In a specific example, when the power module 40 malfunctions, a portable low-power electric water pump is temporarily connected to the return water pipe 30 via a hose. The water pump is started to quickly drain the coolant from the power module 40. After the power module 40 is replaced and the fault is resolved, the water pump and hose are removed and the system is restored to its original state.
[0037] Based on the above technical solution, the quick release device further includes a second valve 70, which is disposed at one end of the branch pipe 60 near the power module 40 and at the connection between the return water pipe 30 and the branch pipe 60.
[0038] By installing a second valve 70 at one end of the branch pipe 60 near the power module 40, the second valve 70 can be opened when the power module 40 fails, connecting the branch pipe 60 and the power module 40, thereby quickly draining the coolant from the power module 40.
[0039] Specifically, the second valve 70 is a three-way ball valve.
[0040] Alternatively, a valve can be installed on both the return water pipe 30 and the branch pipe 60, i.e., a second valve 70 is installed on the branch pipe 60 and a third valve is installed on the return water pipe 30. When the equipment is running normally, the third valve is open and the second valve 70 is closed, and the coolant circulates to the power module 40 to remove heat. When the equipment malfunctions, the third valve is closed and the second valve 70 is opened, and the coolant is forcibly discharged by the pump 50 and flows into the coolant tank 10 through the branch pipe. Alternatively, the third valve can remain open, i.e., the second valve 70 and the third valve are opened simultaneously, relying on gravity to discharge the coolant and returning it to the coolant tank 10 through the return water pipe 30. At the same time, it is forcibly discharged by the pump 50 and flows into the coolant tank 10 through the branch pipe, which greatly shortens the coolant discharge time.
[0041] Based on the above technical solution, the pump 50 is model LPm125.
[0042] This pump 50 features high flow rate and corrosion resistance, is easy to use, and is suitable for coolant media, ensuring rapid drainage of coolant from the power module 40.
[0043] Based on the above technical solution, the device further includes a heat dissipation device 80. The water outlet pipe 20 includes a first water outlet pipe 21 and a second water outlet pipe 22. One end of the first water outlet pipe 21 is connected to the outlet of the coolant tank 10, and the other end of the first water outlet pipe 21 is connected to the coolant inlet of the heat dissipation device 80. One end of the second water outlet pipe 22 is connected to the coolant outlet of the heat dissipation device 80, and the other end of the second water outlet pipe 22 is connected to the inlet of the power module 40.
[0044] By setting up a heat dissipation device 80, the coolant is cooled down, ensuring that the coolant effectively dissipates heat from the power module 40, improving cooling efficiency, and ensuring the normal and stable operation of the equipment.
[0045] Based on the above technical solution, a pressure stabilizing pump 90 is installed on the first section of the water outlet pipeline 21.
[0046] By installing a pressure-stabilizing pump 90 on the first water outlet pipe 21, the coolant is stably delivered to the heat dissipation device 80, thereby cooling the coolant and ensuring that the coolant continuously circulates to effectively cool and dissipate heat from the power module 40, ensuring the stable operation of the equipment. At the same time, the coolant is recycled, effectively saving resources.
[0047] Based on the above technical solution, a temperature sensor, a pressure gauge and a flow meter are also installed on the first section of the water outlet pipeline 21 between the coolant tank 10 and the pressure stabilizing pump 90.
[0048] By installing temperature sensors, pressure gauges, and flow meters on the first water outlet pipe 21, multiple parameters can be monitored and controlled within a safe operating range, thereby improving system safety.
[0049] Specifically, a control cabinet is also provided, which is electrically connected to the pressure stabilizing pump 90, temperature sensor, pressure gauge and flow meter.
[0050] The control cabinet allows you to view the temperature, flow rate, and pressure of the device, and start or stop the pressure stabilizing pump 90. Based on the real-time monitored data parameters, you can also make corresponding adjustments to ensure the stable operation of the device.
[0051] Based on the above technical solution, a first valve 100 is installed on the second section of the water outlet pipe 22.
[0052] By installing a first valve 100 on the second water outlet pipe 22, the first valve 100 can be closed immediately when the power module 40 malfunctions, stopping the supply of coolant to the power module 40 and facilitating the rapid start of the discharge of coolant from the power module 40.
[0053] Optionally, the first valve 100, the second valve 70, or other valves installed on the pipeline can be manual or electric valves. When they are electric valves, they can be electrically connected to the control cabinet to automatically open or close the valves.
[0054] Based on the above technical solution, the return water pipe 30 and the coolant tank 10 are located below the power module 40.
[0055] By placing the return water pipe 30 and the coolant tank 10 below the power module 40, effective circulation of coolant is ensured. Furthermore, in the event of a failure in the power module 40, the coolant inside the power module 40 can still be drained by gravity, further shortening the time required for troubleshooting.
[0056] This invention also provides an SVG system, including the aforementioned coolant release device.
[0057] By setting up a coolant release device, the stable operation of the SVG system is ensured. When the power module 40 fails, the coolant in the power module 40 can be quickly drained and replaced, shortening the fault handling time, improving the fault handling efficiency, thereby increasing the qualification rate of SVG system regulation and ensuring the commissioning rate of the SVG system.
