Description

Technical Field

[0001] This utility model relates to the technical field of low-voltage static var compensation, and in particular to a low-voltage static var compensation device. Background Technology

[0002] Most electrical loads in the power grid, such as motors and transformers, are inductive loads, requiring reactive power during operation. Installing reactive power compensation devices such as parallel capacitors in the power grid can compensate for the reactive power consumed by these inductive loads, reducing the reactive power supplied from the grid to these loads and transmitted through the lines. This reduction in reactive power flow within the grid lowers energy losses in lines and transformers caused by reactive power transmission.

[0003] Among existing low-voltage static var compensators, such as the one disclosed in utility model patent application number 202020619497.6, this utility model's low-voltage static var compensator, by setting up structures such as heat sinks and elastic airbags, can absorb the heat generated by the disconnect switch, capacitor, main busbar, mounting beam, and branch busbar using the heat sinks, and cool it with gas through the heat dissipation channel. Thus, the external air can achieve the cooling effect without contacting the disconnect switch, capacitor, main busbar, mounting beam, and branch busbar, effectively controlling the humidity and temperature inside the enclosure and achieving long-term stable operation of the static var compensator.

[0004] However, during low-pressure static var compensation, the use of rubber airbags can cause the rubber to age too quickly when hot air flows through them, thus reducing the service life of the equipment. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a low-pressure static var compensation device that improves the stability of equipment operation and extends the service life of the equipment by setting up an air pumping mechanism and a driving mechanism, thereby replacing the rubber air bag with a metal air tank during the low-pressure static var compensation process.

[0006] This utility model discloses a low-voltage static var compensator, which includes a heat dissipation mechanism; it also includes a filter mechanism, six sets of air passage mechanisms, six sets of heat conduction mechanisms, three sets of air pumping mechanisms, and a drive mechanism. The filter mechanism is installed at the lower end of the heat dissipation mechanism, the six sets of air passage mechanisms are installed inside the heat dissipation mechanism, the six sets of heat conduction mechanisms are connected to the air passage mechanisms and installed inside the heat dissipation mechanism, and every two sets of air passage mechanisms are connected through a set of air pumping mechanisms. The drive mechanism is installed inside the heat dissipation mechanism.

[0007] The heat dissipation mechanism dissipates heat, the filtration mechanism filters, the air passage mechanism guides air, the heat conduction mechanism conducts heat, the air pumping mechanism pumps air, and the drive mechanism drives the air pumping mechanism. By opening the drive mechanism to drive the air pumping mechanism, the air pumping mechanism drives the gas. The filtration mechanism filters the intake gas, the air passage mechanism introduces hot gas, the heat conduction mechanism removes heat, and the heat dissipation mechanism discharges heat. Thus, in the low-pressure static var compensation process, replacing the rubber airbag with a metal air tank improves the stability of equipment operation and extends the service life of the equipment.

[0008] Preferably, the heat dissipation mechanism includes a heat dissipation chamber, four sets of heat dissipation fins, an air inlet, and an exhaust outlet. The four sets of heat dissipation fins are installed inside the heat dissipation chamber, the air inlet is installed inside the heat dissipation chamber, and the exhaust outlet is installed at the left end of the heat dissipation chamber. Heat dissipation is achieved through the heat dissipation chamber in conjunction with the heat dissipation fins, hot air is introduced through the air inlet, and gas is discharged through the exhaust outlet.

[0009] Preferably, the filtration mechanism includes a liquid tank, a filter screen, an air inlet pipe, and a drain outlet. The liquid tank is installed at the lower end of the heat dissipation chamber, the filter screen is slidably installed inside the liquid tank, the air inlet pipe is installed at the right end of the liquid tank, and the drain outlet is installed at the lower end of the liquid tank. Hot air is drawn in through the air inlet pipe, filtered through the liquid in the liquid tank for preliminary cooling, and discharged through the drain outlet while the liquid is filtered through the filter screen.

[0010] Preferably, the gas passage mechanism includes a connecting pipe, a one-way valve, and a nut. The connecting pipe is installed inside the heat dissipation chamber, the one-way valve is threaded onto the lower end of the connecting pipe and is threaded to the air inlet, and the nut is threaded onto the connecting pipe. The gas flow direction is controlled by the one-way valve, the gas is guided through the connecting pipe, and the nut is used for sealing and fixing.

[0011] Preferably, the heat conduction mechanism includes a heat conduction block, and a heat conduction air channel is provided inside the heat conduction block. The heat conduction block is connected to the connecting pipe by threads. Heat is absorbed through the heat conduction block, and the heat conduction air channel guides the hot air to increase the absorption area.

[0012] Preferably, the air pumping mechanism includes two sets of air chambers, two sets of pump sleeves, and a second check valve. The two sets of air chambers are respectively connected to the connecting pipe and the first check valve via threads. Each set of air chambers is slidably mounted with a set of pump sleeves, and the two sets of pump sleeves are connected by the second check valve. The airflow in the air chamber is pumped by sliding the pump sleeves, and the direction of airflow is controlled by the second check valve.

[0013] Preferably, the drive mechanism includes three sets of fixed sleeves, three sets of slide rods, a crankshaft, a motor, and three sets of connecting rods. A set of fixed sleeves is fitted onto every two sets of pump sleeves, and a set of slide rods is installed on each set of fixed sleeves. The crankshaft is rotatably mounted inside the heat dissipation chamber, and the motor is also mounted inside the heat dissipation chamber, with its output end connected to the crankshaft input end. Each set of slide rods is rotatably connected to the crankshaft via a set of connecting rods. By turning on the motor, the crankshaft is driven to rotate. Simultaneously, the crankshaft rotates, and the slide rods reciprocate along with the connecting rods, thereby driving the pump sleeves with the fixed sleeves.
