Bộ điều khiển nhiệt độ cho máy biến áp tự dùng, LD dry-type transformer temperature controller LD-B10-A220D
Overview
LD-B10-220 series dry-type transformer temperature controller (referred to as temperature controller) is an intelligent controller designed for the safe operation of dry-type transformers. The thermostat adopts single-chip technology, and uses three platinum thermal resistors embedded in the three-phase winding of the dry-type transformer to detect and display the temperature rise of the transformer winding, and can automatically start and stop the cooling fan to perform forced air cooling on the winding, and can Control over temperature alarm and over temperature trip output to ensure that the transformer is running in a safe state.
