Source: InternetPublisher:念念Brown Keywords: Thyristor temperature control circuit resistance furnace BSP Updated: 2021/03/01
It is a 45kW box-type resistance furnace heat treatment temperature automatic control circuit. The main circuit is controlled by high-power bidirectional thyristor
. A thermocouple potentiometer KP is used as the measurement and control component.
The indicator lights H3~Hs respectively indicate the connection status of the three-phase loads L1, L2 and L3.
