1.Product overview
Dry-type transformers need to be equipped with dry-type transformer temperature controller and terminal box, customers need to purchase separately, and installed in different locations, the process is slightly cumbersome. BWDK-3206A series of dry-type transformers temperature controller integrated dry-type transformer temperature monitoring, terminal box and other expansion features, so that customers experience better, more convenient installation.
2.Functional features
Temperature monitoring of dry-type transformer: three-phase circuit measurements and display; the maximum display; input open circuit and failure self-inspection display and output; cooling draught fan manual/automatic start-stop display and output; over-temperature alarms, over-temperature trip display and output; displayed value compensation of all channels; "black box"; control for timing start-stop of the draught fan; Temperature simulation. The full series uses the principle of number uniqueness to define input& output terminal functions, in order to facilitate the client drawing design, field wiring and control box change. Communication/simulation current is output from the terminals, no need to the intermediate conversion terminal. For the sensor cable interface, the front-end installation method is adopted to provide easy installation for clients.
Terminal box: Air switches and a certain number of terminals will be added and sufficient space will be reserved for wiring, in order to achieve the functions of the terminal box.
Extended functions: Monitor and control the ambient temperature and humidity as ll as carry out relevant functional expansion based on client demands.
