Embodiment Construction
[0009] A three-phase water-cooled AC electronic load cabinet operating in an isolated grid of a hydropower station, such as figure 1 As shown, it includes a cabinet body 110 , a water inlet pipe 120 , a water outlet pipe 130 and a resistance tube assembly. The water inlet pipe 120 , the water outlet pipe 130 and the resistance tube assembly are arranged on the cabinet body 110 .
[0010] The water inlet pipe 120 is used to connect the main water pipe of the hydropower station, and connects cold water to the cabinet body 110; the resistance tube assembly is used to connect the outlet line of the generator of the hydropower station, and heat the cold water in the cabinet body 110 after power-on; the outlet pipe 130 Used to discharge heated hot water. Specifically, the cabinet body 110 includes a bottom plate and side walls fixedly arranged around the bottom plate. The bottom plate and the side walls form a water storage cavity. When the cabinet body 110 is placed, the bottom pl...

The invention relates to a three-phase water-cooling alternating current electronic load cabinet for a hydropower station run in an isolated power grid. The three-phase water-cooling alternating current electronic load cabinet comprises a cabinet body, a water inlet pipe, a water outlet pipe and resistance tube assemblies, wherein the water inlet pipe is connected with a main water guiding pipe of the hydropower station to feed cold water into the cabinet body; the resistance tube assemblies are connected with generator terminal outgoing lines of the hydropower station and heat the cold water in the cabinet body after being electrified; the water outlet pipe is used for discharging heated hot water. According to characteristics of abundant water resource and pressurized water flow of the hydropower station, the resistance tube assemblies are mounted in the cabinet body, and water is full of the cabinet body through the water inlet pipe; when the resistance tube assemblies are electrified and consumes the power, the water flow is heated and the hot water is discharged through the water outlet pipe; the surplus power of the hydropower station is consumed by utilizing the hot water, the adjustment is convenient, the costs are low and the size is small. According to the three-phase water-cooling alternating current electronic load cabinet for the hydropower station run in the isolated power grid, the heat is brought away by the water flow, but the environment temperature is not affected; the water resource of the hydropower station is fully utilized, and the invention is suitable for application of hydropower station.
Description
technical field [0001] The invention relates to the technical field of AC electronic loads, in particular to a three-phase water-cooled AC electronic load cabinet for isolated grid operation of a hydropower station. Background technique [0002] Existing AC electronic loads generally use water resistance cabinets or power resistance cabinets to consume power. The traditional water resistance cabinet mainly includes three independent water tanks. There is a fixed copper pole plate at the bottom of the water tank, and a fixed copper pole plate at the top of the water tank. The primary and secondary lines are respectively led out, and the resistance value is changed by driving the plate up and down. This method is mainly used for starting motors, and has disadvantages such as troublesome adjustment of load resistance, high cost, and poor resistance linearity, and cannot be applied to hydropower station applications. Contents of the invention [0003] Based on this, it is nec...
