An overview,

With the development of economy, high and low voltage line gradually realize cable. Cable tunnels, however, are not as easily patrolled by hand as overhead lines. How to quickly understand the comprehensive information in the cable tunnel and how to quickly locate the fault point has become an urgent problem to be solved.

Therefore, our company has developed a cable tunnel integrated online monitoring system. The staff can browse the water level, smoke, toxic and harmful gases, grounding current of cable sheath and other information in the cable tunnel through the mobile phone APP. When the alarm occurs, the alarm content will be sent to the designated mobile phone in the form of SMS. In order to inform the staff as soon as possible timely processing.

Second, water level monitoring subsystem

When the water level in the cable tunnel reaches the set value, the SMS alarm is triggered and the drainage pump can be linked.

Working voltage DC12-24V

Alarm value 10cm, 20cm, 30cm(adjustable)

Alarm accuracy ±1cm

Three, smoke monitoring subsystem

When the smoke in the cable tunnel reaches the alarm value, the SMS alarm is triggered

Working voltage DC12-24V

Detection mode photoelectric induction

Working temperature -20 -- 55℃

Fourth, cable sheath grounding current monitoring subsystem

Current sampling range 0-300A

Sampling accuracy: 12bit

Accuracy class 0.5

Rated frequency 50Hz

Toxic and harmful gas monitoring

The system can be equipped with carbon monoxide, methane and other gas transmitters.
