Description

Technical Field

[0001] This utility model relates to the field of SVG water cooling technology, specifically to a voltage stabilizing device based on an SVG water cooling circulation system. Background Technology

[0002] With the rapid development of wind power generation technology, the demand for large-capacity dynamic reactive power compensation equipment is becoming increasingly urgent. SVG (Static Var Generator) has attracted widespread attention due to its fast dynamic response and low grid-connected harmonics. SVG is equipped with a water-cooled circulation system, including a fan, water pipes, a water pump, and a storage tank. This system allows the heat generated during SVG operation to be carried away by cooling water. The cooling water is transported to the heat exchange fins through the water pipes. The fan draws in ambient air and creates an airflow that blows onto the heat exchange fins, further carrying away the heat from the fins and cooling the cooling water, ensuring the effective operation of the cooling system.

[0003] In existing SVG water-cooled circulation systems, coolant loss is generally caused by leakage at pipe joints that allow air to enter, or by cracks in the pipes due to thermal expansion and contraction that allow air to enter. Traditionally, expansion tanks are used to replenish coolant and maintain the system's operating pressure. The expansion tubes use an air bladder structure, but after a period of operation, the air bladder will rupture to a certain extent, causing the system to fail to reach the operating pressure and triggering an alarm. Utility Model Content

[0004] The technical problem solved by this utility model is to solve the problem that the SVG water-cooled circulation system cannot operate continuously due to leakage, and to solve the problem that the circulation pump life is reduced and the heat exchange efficiency is reduced when air is introduced into the pipeline.

[0005] To solve the above problems, this application provides the following technical solution:

[0006] A voltage stabilizing device based on an SVG water-cooled heat dissipation circulation system includes a gas-liquid displacement tank.

The water outlet pipe is connected to the bottom of a buffer tank, and the outlet pipe at the bottom of the buffer tank is connected in parallel to the inlet pipes of a first circulation pump and a second circulation pump. The outlet pipes of the first circulation pump and the second circulation pump are connected in parallel to the inlet pipe of a heat dissipation fan, and the outlet pipe of the heat dissipation fan is connected to the inlet pipe of a power unit module.

[0007] The outlet pipe is equipped with a drain valve.

[0008] The gas-liquid replacement tank is equipped with a first level gauge.

[0009] The inlet pipe on the top of the gas-liquid replacement tank is connected to a water tank, which is a sealed water tank and is equipped with multiple first gas valves.

[0010] The gas-liquid replacement tank is equipped with a water inlet valve and a centrifugal pump on the inlet pipe at the top, and the centrifugal pump is located in the water tank.

[0011] The top of the buffer tank is a convex semi-hollow sphere, which facilitates the accumulation of gas in the cooling water inside the buffer tank. The gas outlet pipe at the top of the buffer tank is connected to the gas inlet pipe at the top of the gas-liquid replacement tank through a vent valve.

[0012] Both the inlet and outlet pipes of the first and second circulating pumps are equipped with valves.

[0013] The inlet pipe of the power unit module is also connected to the outlet pipe of the water supply pump, and the inlet pipe of the water supply pump is connected to the water supply tank, which is equipped with a third level gauge and a second air valve.

[0014] The outlet pipe of the power unit module is connected to the top of the buffer tank. The gas outlet pipe at the top of the buffer tank is also connected in series with the inlet of the pressure gauge and the vent valve. The outlet pipe of the vent valve is connected to the gas inlet pipe at the top of the gas-liquid replacement tank.

[0015] The outlet pipe of the power unit module is connected to the inlet of the one-way valve, and the outlet of the one-way valve is connected to the top of the buffer tank.

[0016] Preferably, the buffer tank is equipped with a second level gauge.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This device has a simple structure and is easy to operate. The gas-liquid replacement tank can provide pressure protection for the buffer tank, discharge the gas inside the pipeline, extend the service life of the first and second circulation pumps, increase the operating efficiency of the equipment, and reduce manual maintenance costs.

[0019] 2. By setting up a gas-liquid replacement tank, a buffer tank, and a water pump, this device can promptly exchange and discharge the gas in the SVG water-cooled heat dissipation circulation system and replace it with new coolant, thus preventing pressure drop in the SVG water-cooled heat dissipation circulation system and improving the stable operation of the SVG water-cooled heat dissipation circulation system.
