Type: DL-110D

Wireless electric equipment alarm system

 

 

Products Overview

DL - 110D type electric computer general monitoring alarm mainly used in power grid power line of electric power system, supply transformer etc. power supply unit and s anti shear resistance, theft, prevent damage. System extension adopts American imported microprocessor control technology, advanced wireless data transmission technology, to monitoring alarm the loss of phase in the power grid transmission lines, effectively prevent power grid power lines,、supply transformer be stolen and damaged. Extension adopts the aluminum casting shell seal, good waterproof properties, suitable for complicated field environment. The machine newly increased break zero line alarm functions, which can effectively prevent power line zero line bad contact, power line zero line break line plays a warning function to the damage of electric equipment, can farthest reduce the loss of electric equipment for power line zero line break line.

 

Have a monitoring alarm about faulted neutral line, loss of phase and outage for power grid transmission line

For power supply circuit, respectively AC380V A,B,C phase, zero line 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 ,zero line has been cut and the loss of phase alert code of the A,B,C phase, zero line.

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 host shows the address code by monitoring extension and outage alert code P.

The whole system composes of several extensions and one system host, 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.

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.

The aluminum casting shell seal, good waterproof properties, suitable for complicated field environment.
