This article Pacific Security Network Xiaobian introduces the principle principle of power transformer anti-theft alarm system, power transformer anti-theft alarm system. This system is mainly used for power line and transformer anti-theft alarm. Its characteristics are: no distance limitation, no quantity restrictions, no weather influence, only one alarm center can be set up. The microcomputer is equipped with the alarm center software, which can display the actual location of the alarm transformer and the fault line in an electronic map. After the printer is connected to the printer in real time, the data can be recorded, the date of the alarm, the time and the extension number can be printed for future reference, and the investment cost can be reduced. It has the characteristics of practical function, good quality, stable and reliable work, and is suitable for outdoor environment use. It is widely used in the safety protection of all outdoor electrical equipment such as electric power, petroleum and mining.
Principle of power transformer anti-theft alarm system: wireless monitoring alarm host is installed on the pole of the monitored power line or next to the transformer. Once the power line or transformer is stolen, three-phase disconnection or power failure, the monitoring alarm host immediately detects and uses wireless GSM short message. And the voice mode receives the host alarm to the GSM, the receiving host receives the alarm signal and transmits the data to the microcomputer. The microcomputer analyzes and judges the alarm host and the line that may be faulty after receiving the alarm software, and the screen displays the alarm date, time, and alarm extension number. , faulty transformer and possible faulty lines, and display the actual location of the alarm transformer and faulty line by electronic map, and store the alarm data in the database for inquiry. After the duty leader got the alarm, he immediately sent police to the scene to check the situation and deal with the relevant issues.
Composition: alarm host, dual-infrared probe, siren, receiving host, alarm center software
Features: (1) GSM Chinese short message alarm, intuitive and reliable, transmission distance is not limited;
(2) Two wired infrared zones, four wire break zones, which can be customized. The normally open/normally closed contact alarm mode can be selected by self-programming, and the alarm contact adopts photoelectric isolation input to prevent external strong electricity and lightning strike damage, and the alarm state is actively reported to the remote side when the alarm is restored;
(3) A central number and up to 7 short message alarm numbers, can also be automatically alerted by the alarm center computer, electronic map display, with powerful network alarm function;
(4) It has the function of sending start report and remote inspection (test report and timed test test), which can find out whether the work of the alarm host is normal;
(5) Three-phase detection, which can accurately detect and report any phase abnormality;
(6) Chinese alarm information is used in each defense zone, and the user can change the content of the alarm information by himself;
(7) Built-in 12V spare charging polymer battery, automatic charge and discharge control, automatic switching after power failure, can be continued for 48 hours
Shandong Fiberglass Group Corp. is a state owned enterprise with registered capital RMB400million, covering an area of 800,000sqm.
