Abstract

An alternating current power supply distribution unit alarm device used for communication is disclosed. A fault alarm implementation device which is suitable for an alternating current distribution unit is disclosed, wherein the fault comprises fusing, tripping, overvoltage, undervoltage and the like. The device comprises an alarm processing plate, a plurality of signal acquisition plates and a connection cable. The alarm device adopts a mode of directly monitoring potentials of two ends of a protection device. A traditional fault acquisition mode in which a circuit breaker matches with auxiliary alarm contacts is replaced so that an installation space used for the auxiliary alarm contacts can be vacated and a system integration degree is increased. Simultaneously, system cost is reduced.

Description

Communication AC power allocation units alarm device
Technical field:
The present invention relates to communication distribution field, particularly relate to communication AC power allocation units alarm device.It is applicable to effective operation of on-line monitoring AC power distribution system, in time sends indication and alarm when distribution breaks down, thereby can process rapidly and fix a breakdown.
Technical background:
Traditional AC distribution indicating fault adopts the method for the additional minor alarm contact of isolating switch to carry out Collection, and this minor alarm contact need be installed on the isolating switch side, takies the installing space of about half isolating switch more, is unfavorable for that the space of isolating switch is arranged; And the price of this minor alarm contact is high, and the minor alarm contact price of configuration is higher than the price of isolating switch itself far away sometimes.Therefore, be necessary to design a kind of more economical, structure of practicability and effectiveness more.
Summary of the invention:
Purpose of the present invention will provide a kind of communication AC power allocation units alarm device exactly, and it can overcome traditional AC distribution indicating fault, existing above defective.The object of the present invention is achieved like this; communication AC power allocation units alarm device; it is characterized in that: signal acquiring board is made of the testing circuit of multichannel photoelectricity isolation; the lower end that its test side is connected to protection device isolating switch or fuse is load end; the potential change of monitoring and protecting device lower end; when protection device tripping operation or fusing; its lower terminal potential and power input current potential produce voltage difference; thereby make the photoelectrical coupler conducting in the testing circuit; alarm signal is after circuit amplifies; send the alarming processing plate to, the alarming processing plate sends the visible audible and visual alarm signal of audible.Described alarming processing plate can receive and process the alarm signal that the multiplexed signal sampling plate sends simultaneously, can send the visible audible and visual alarm of audible.Described alarming processing plate when detecting the input supply voltage overrun, can send overvoltage and undervoltage alarm signal.Described signal acquiring board; adopt the high sensitivity photoelectrical coupler that the protection device of AC power allocation units is detected, in case find fusing and tripping operation, namely light this road stand by lamp; and producing an alarm signal, this alarm signal can be delivered to the alarming processing plate and focus on.The direct current that alarm device employing communications equipment room very easily obtains-48V Power supply, even exchange complete dead electricity, alarm device still can work and export the dead electricity alarm signal; Between signal acquiring board and the alarming processing plate, all adopt photoelectrical coupler to carry out electrical isolation between alarm device and the distribution major loop, in the alarm device, guarantee security.Adopt modular design, connector connects, can be according to the way increase and decrease signal acquiring board of allocation units.The present invention does not take separately the space of arranging of isolating switch, does not affect the operation of isolating switch, and cost is safe and reliable.Modular design, connector connects, can be according to the way increase and decrease signal acquiring board of allocation units, installation and maintenance are flexible.Adopt the mode of electronic circuit directly signals collecting to be carried out in the isolating switch lower end, produce alarm signal.Do not need to use the minor alarm contact, thereby vacate the installing space of minor alarm contact, improve level of integrated system.Also reduced simultaneously system cost.The present invention is equally applicable to adopt fuse as the Alternating Current Unit of protection device.
