DL-110A type electric power equipment guard against theft and alarm system extension is mainly use for power grid power line of power-supply system, supply transformer etc. power supply equipment and lines as anti shear resistance, theft, prevent damage. The system extension adopts the single chip computer control wireless data transmission technology, and the power grid charging line loss of phase, outage monitoring alarm, effectively prevent power grid power line, supply transformer are stolen and destroyed, The extension adopts aluminum casting shell seal, good waterproof properties; it is suitable for outdoor installation.

 

For power supply circuit (AC380V), phase power monitoring alarm.

 

For power supply circuit, respectively AC380V A, B, C phase break line and have a testing detection to judge, then send different wireless data information. The extension of the system are show the address code by monitoring when A, B, C has been cut and the loss of phase alert code of the A, B, C phase.

 

The normal supply of power supply circuit testing, power supply circuit outage (three-phase four-wire outage at the same time) or have sent the outage wireless data information about the abnormal phase line voltage for extension, the system main engine shows the address code by monitoring extension and outage alert code P; and shows E means power transmission after blackout.

 

The whole system composes of several extensions and one system main engine, to prevent the same supply circuit work abnormally. Several extension will send abnormal alarm information at the same time, blocked the wireless receive channel, the extension automatic set time gap random stagger launch function, it can guarantee system host receives all messages from each extension.

 

System extension will detect by itself when it during normal working, and send the self-checking information every 24 hours, system host will show extension address by monitoring and alarm code H when system host can not receive the normal operation self-checking information in 72 hours.

 

Extension set a circumscribed sense line and supply transformer shell winding, it will monitoring alarm for supply transformer destruction, move function.

 

An extension infrared detector is used to detect intruders’ infrared radiation of human’s body (optional suitable for indoor use)

 

Extension wireless remote control, code, arming, disarming, detection (Optional)

 

Extension enter micro-consumption run in the power grid outage situation, built-in support battery for power about a month, maintain normal operation of extension. (Optional solar panels to power supply, guarantee system normal work)

 

Extension can protect the copper coil transformer winding in the power grid (Optional)

 

Shell, aluminum casting seal, waterproof properties is good, suitable for outdoor installation.
