(1) Circuit breaker status display:
When closing, the closing contact is closed, and the red analog bar 01 lights up.
When opening, the opening contact is closed, and the green analog bar 02 lights up.
(2) Display of handcart position:
When the working position contact is closed, the red vertical analog bar 03 lights up.
When the test position contact is closed, the green horizontal analog bar 04 lights up.
(3) Grounding knife position indication:
The contact is closed, and the red analog bar 05 is on, indicating that the grounding is closed.
The contact is disconnected, and the green analog bar 06 is on, indicating that the grounding is disconnected.
(4) Energy storage status indication:
The contact is closed, and the red light 07 is on, indicating that the energy has been stored.
Note: In the power-off state, all the luminous indications are off, and the above contact signals are all from the auxiliary contacts of the circuit breaker.
(5) High voltage live indication LED starting voltage (KV): bus voltage × 0.150.65.
Latching start control voltage (KV): busbar voltage × 0.65.
(6) Temperature and humidity control function:
Number of sensor channels: two channels of condensation + two channels of temperature or one channel of condensation + one channel of temperature.
Logical relationship: start heating when temperature <5℃ or humidity>90%RH (two-way heating);
Stop heating when temperature>15℃ or humidity<80%RH;
When the temperature is >45℃, the output of the overheat exhaust air relay;
When the temperature is less than 35°C, the overheated exhaust air stops outputting.
Disconnection alarm: The temperature and humidity sensor or heater is disconnected, and the corresponding alarm indicator light is on.
Manual heating switch: The switch can be in two states, automatic or manual, usually in the automatic state. At this time, the temperature and humidity control logic is the same as above. When the switch is pressed, it is in the manual forced heating state.
(When the ambient temperature is lower than 15°C, after the general heating is canceled, the heater will stop heating to 15°C)
(7) Intelligent anti-mistake voice prompt:
When the handcart is between the test position and the working position, when the circuit breaker is in the closed state, there will be a voice prompt of "Please open the circuit breaker" until the circuit breaker is opened;
When the handcart is not in the test position or working position, if the grounding switch is forced to close by mistake, there will be a voice prompt of "Please disconnect the grounding switch" until the grounding switch is opened;
When the circuit breaker is closed and the handcart is not in the test position or working position, if the grounding knife switch is forced to close by mistake, there will be a voice prompt of "Please disconnect the circuit breaker, please disconnect the grounding switch";
When the device is powered on, there will be a voice prompt "This circuit is live, do not approach it";
When the device is powered on and the three-phase high voltage is charged, there will be a voice prompt of "This circuit is live, do not approach it".
