Automatic Voltage Stabilizer Provides Early Warning To Avoid Gas Outage And Hidden Dangers

In order to ensure safe and reliable gas use, an automatic control system for the pressure regulating box is introduced. The system can give an early alarm when an abnormality occurs in Automatic Voltage Stabilizer, but before the cut-off device is automatically activated, so as to avoid large-scale gas outages.

The main function of the automatic voltage regulator is to adjust the pressure of natural gas to the applicable range for residents' homes, ensuring the normal use of gas for nearly 500,000 residents in the city. In the past, the equipment was regularly maintained on site by Hong Kong and China technicians. If there was an abnormality in the inlet and outlet pressure of the automatic voltage regulator, it could only be discovered during regular maintenance. If the outlet pressure of the automatic voltage regulator exceeded the set range during non-maintenance, the automatic cut-off device would be activated, but it would cause large-scale gas outages in the entire community, causing great trouble to residents and even gas safety hazards.

Based on the pilot installation of low-power SCADA (data acquisition and monitoring control) systems for 50 regional pressure regulating boxes last year, the company continued to automate 140 pressure regulating stations. After installing the scada system, the pressure data of the automatic regulator can be transmitted to the dispatcher in real time, and the remote monitoring system will issue an alarm when the inlet and outlet pressure is abnormal and before the automatic regulator starts the automatic cut-off device, reminding the technicians to rush to the site to check the situation as soon as possible.

It is reported that since the trial operation, there have been several alarms. After the technicians rushed to the site to deal with it in time, a large area of ​​gas outages in the residential area was avoided.

While renovating the pressure regulating boxes in residential areas, Hong Kong and China Company stated that it will also gradually renovate the pressure regulating boxes of industrial and commercial customers.
