ZYYS6005 tunnel integrated online monitoring system

Summarize

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

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

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

Smoke monitoring subsystem

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

Working voltage: DC12-24V

Detection method: photoelectric induction

Operating temperature: -20-55℃

Cable sheath grounding current monitoring subsystem

Current sampling range: 0-300A

Sampling accuracy: 12bit

Accuracy rating: 0.5

Rated frequency: 50Hz

Toxic and harmful gas monitoring

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