Cooling device for high-voltage vacuum circuit breaker and assembly method thereof

Abstract

The invention discloses a cooling device for a high-voltage vacuum circuit breaker and an assembly method thereof. The cooling device comprises a fan. The fan is provided with a casing body and a motor. The end part of the motor is rotationally connected with an impeller. The impeller is arranged in the casing body. The casing body is provided with a first air outlet. The cooling device is characterized in that a fixation seat is arranged above the casing body; the casing body is slidably connected with the fixation seat; a lifting component is arranged at the top of the fixation seat; and thelifting component controls the fixation seat to lift. The method comprises the steps that a the size is determined; b the fixation seat and the lifting component are arranged; c the fan and a rotating adjustment component are arranged; and d the installation is completed. According to the invention, the position of the fan is adjustable; a high temperature point can be quickly cooled; the coolingdevice is arranged in a cabinet body to effectively eliminate hot air in the cabinet body, which reduces the temperature in the cabinet body; the service life of the vacuum circuit breaker can be prolonged; and the probability of hidden safety hazards can be reduced.

Description

technical field [0001] The invention belongs to the technical field of high-voltage power distribution equipment in thermal power plants, and in particular relates to a cooling device for a high-voltage vacuum circuit breaker and an assembly method thereof. Background technique [0002] The main transformer vacuum circuit breaker, the main transformer is a very important device in the electrical primary system of the thermal power plant, and together with the generator, it is called a generator-transformer unit. It is the main equipment for transmitting the electric energy of the generator. The vacuum circuit breaker can not only cut off or close the no-load current and load current. The circuit breaker cabinet adopts armored mid-mounted AC metal-enclosed switchgear. The circuit breaker is an indoor high-voltage vacuum circuit breaker, including two parts: the cabinet body and the removable parts. The cabinet body is divided into a circuit breaker room and a busbar by an in...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and to provide a cooling device for a high-voltage vacuum circuit breaker and its assembly method. By slidingly connecting the fan to the fixed seat, a lifting assembly is installed on the top of the fixed seat to lift the The component controls the fixed seat to lift, and the fixed seat drives the fan to move up and down. The fan can slide back and forth on the fixed seat, which realizes the adjustable position of the fan and can quickly cool down the high temperature point. A cooling device is installed in the cabinet It can effectively remove the hot air in the cabinet, reduce the temperature in the cabinet, and prolong the service life of the vacuum circuit breaker, thereby reducing the probability of safety hazards
