switch cabinet intelligent control device

1.No source point input:
★When the handcart working position contact is closed, the red vertical analogue strip glows, showing that the circuit breaker handcart is in the working position;
★When the handcart test position contact is closed, the green horizontal analogue strip glows, indicating that the circuit breaker handcart is in the test position;
★When the handcart is located between the test and working positions, the red vertical and green horizontal analogue strips flash at the same time;
★When the handcart is moved out of the switchgear cabinet, both the red vertical and green horizontal analogue strips do not glow, indicating that the handcart is disconnected;
★When the normally open node of the circuit breaker is closed and the normally closed node is open, the red analogue strip glows, indicating that the circuit breaker is closed;
★When the normally open node of the circuit breaker is open and the normally closed node is closed, the green analogue strip glows, indicating that the circuit breaker has been tripped.

2. Charged display: it can respectively indicate whether A, B and C phases are charged or not, and at the same time provide charged blocking contact.
★ LED start voltage (KV): rated phase voltage x 0.15～ 0.65; ★ LED start voltage (KV): rated phase voltage x 0.15～ 0.65; ★ LED start voltage (KV): rated phase voltage x 0.15～ 0.65
★ Latching start voltage (KV): rated phase voltage x 0.65; ★ Latching start voltage (KV): rated phase voltage x 0.65; ★ Latching start voltage (KV): rated phase voltage x 0.65
★When the three phases are not charged at the same time, the blocking release lamp lights up and starts the electromagnetic lock action;
3. With digital temperature and humidity control function;
★To temperature and humidity using digital display, directly display the cabinet temperature and humidity status;
★Control mode: can be with 1~2-way heater, when the ambient humidity > 90% RH, start heating, when the ambient humidity “75% RH, exit heating;
When the ambient temperature “40C, the heater unconditionally exit. For the cabinet temperature and humidity, users can also choose manual heating as needed;
★ disconnection alarm: any one way heater disconnection, the alarm indicator light (also according to user requirements to start the exhaust).
4.Communication function
MODBUS protocol mode, Rs485 interface. It can form a real-time microcomputer error-proof monitoring system with other equipment in the substation.
