Abstract

The invention discloses a power resistor with a double-circuit cooling system. The power resistor is characterized by comprising a shell, wherein a top cover is arranged on the top of the shell; a main body is arranged in the shell; a cooling mechanism is formed by the main body and the top cover; a cooling box and a cooling pipe are arranged in the middle of the cooling mechanism; two ends of the cooling box and two ends of the cooling pipe are communicated with the top cover and a bottom box at the bottom of the main body; a resistor body is arranged in the cooling box; a water inlet and a water outlet are formed in the shell; a terminal is arranged on the top cover. The power resistor has the characteristics of being small in size, convenient to install, great in cooling convenience and the like.

Description

technical field [0001] The invention relates to a power resistor with a double-circuit cooling system, which is a high-power resistor suitable for high and medium voltage systems, and is mainly used for brakes on reservoir gates, brakes on rotating platforms, and various high-power brakes. The utility model relates to an application device of resistance, which belongs to the field of resistors. Background technique [0002] At present, the existing resistors are large in size, high in heat generation, and difficult to install, which can no longer meet the requirements of various drilling platforms and large electrical equipment for braking resistors. [0003] At present, a 500KW resistor needs to be composed of five 500*700*2000mm resistance cabinets. The resistance cabinet body can reach 350-400 degrees during operation. Set up fences and protective devices to ensure a certain safety distance. Because of its high temperature and large heat radiation, it has a great impact ...
