Problems solved by technology

[0003] However, when a certain module fails inside the current control cabinet, it affects the normal operation of other modules and affects its work. At the same time, the number of outgoing lines of the module is large, and when it fails at night, the interior cannot be illuminated, making maintenance and replacement more inconvenient

Abstract

The invention relates to the technical field of transformers, and discloses a ZH-BFK type modular transformer air cooling intelligent control cabinet. The top of a control cabinet main body is integrally provided with a cabinet top, the front surface of the control cabinet main body is hinged with a cabinet door, and the middle position of the cabinet door is provided with a visual window; an aircooling unit intelligent control module and a fixing plate are installed in the control cabinet body from top to bottom, a base is integrally installed at the bottom of the control cabinet body, a cooler intelligent control module is installed in the fixing plate, and heat dissipation holes are formed in one side of the base. And an illuminating lamp is slidably mounted in front of the fixed platein the control cabinet main body. The PLC can realize parallel control of all the ZHFZK modules through a hardware logic control feedback mode, and operation of other modules is not affected when a certain module fails. And meanwhile, the PLC also adopts a software communication mode to realize redundancy control on each module, so that the reliability is greatly improved.

Description

Technical field[0001]The invention relates to the technical field of transformers, in particular to a ZH-BFK type modular transformer air-cooled intelligent control cabinet.Background technique[0002]In 110kV, 220kV, 330kV, 500kV, 750kV, 1000kV oil-immersed transformers, three cooling methods are mainly adopted: natural oil circulation air cooling, forced oil circulation air cooling and forced oil circulation water cooling. Most of them use natural oil circulation air cooling and forced oil circulation air cooling. ZH-BFK transformer air-cooled intelligent control cabinet is an intelligent control cabinet designed for these two cooling methods.[0003]However, when a module in the current control cabinet fails, it affects the normal operation of other modules and affects its work. At the same time, the number of outgoing wires of the module is large, and when it fails at night, its interior cannot be illuminated, which makes maintenance and replacement. More inconvenient. Therefore, th...
