Excitation device screen cabinet for generator

Abstract

The invention discloses an excitation device screen cabinet for a generator, and relates to the field of electric power engineering, and the excitation device screen cabinet comprises a cabinet body, one side of the cabinet body is provided with a moving assembly, the other side of the cabinet body is connected with a cabinet door, the cabinet body is internally provided with an inner cavity, the upper part of the interior of the cabinet body is provided with an air duct, and the interior of the air duct is provided with a fan. Through the motor, the filtering sponge, the chain, the air guide frame, the buffer pad, the beating frame, the electric push rod and the steel wire rope, the filtering sponge filters the entering airflow, and compared with an existing dustproof net, the filtering sponge has the better dust filtering capacity, so that dust entering is effectively reduced, the filtering net mainly prevents small or large impurities such as stones from entering, and the service life of the dustproof net is prolonged. Afterwards, the entered airflow passes through the fan and the air duct to enter the cabinet body, and meanwhile, the airflow is prevented from entering the lower part of the interior of the shell through the air guide frame, so that the surface of the filtering sponge is conveniently cleaned, the surface of the filtering sponge is prevented from being covered with dust, and the influence on the airflow is reduced.

Description

technical field [0001] The invention relates to the field of electric power engineering, in particular to an excitation device panel cabinet for a generator. Background technique [0002] Excitation device refers to the electrical control device in the excitation system of the synchronous generator that can control and regulate the excitation current except the excitation power supply. Almost all of the secondary systems in the substation need to use the panel cabinet, and the excitation device will also be installed inside the panel cabinet. [0003] Existing excitation device panel cabinets for generators will open a number of holes on both sides of the cabinet to facilitate air circulation to dissipate heat from electrical equipment when in use. After being used for a long time, the surface of the net is easily covered by dust, which will slow down the air circulation and affect the heat dissipation of the electrical equipment. The cabinet is transported by a trolley, b...
