Description

Intelligent type low-voltage power distribution network decompression power alarm terminal

Technical field

The invention belongs to power technology field, be specifically related to a kind of decompression power alarm terminal.

Background technology

Current, intelligence distribution is just carried out like a raging fire, the task object of " platform district does not have a power failure " that power industry proposes, power distribution network has been proposed to requirements at the higher level, still, according to the actual fact, power distribution network still needs further upgrading, the problems such as especially platform district 400V aging circuit, wire diameter be thin still exist, and the factor such as the indoor aging circuit of electricity consumer, causes the situation of the distribution transforming of platform district or ammeter box tripping operation power-off to happen occasionally in addition.

In the time there is platform district or the situation of ammeter box decompression power-off, equipment management personnel can not obtain effective information in time, can extend the time of restoring electricity unavoidably, simultaneously, along with the raising of resident living level, daily life is also more and more higher to electric degree of dependence, has a power failure once there is tripping operation, very easily cause and report for repairment, or even the generation of the situation of complaint.

Existing power failure alarm device is generally audio alert or buzzer warning, and the scope of application is the Workplaces such as industrial and mining enterprises, cultivation, be not applicable to the terminal equipment of the public distributing net platform region of monitoring, ammeter box powering-off state, this terminal is based on intelligent distribution construction demand, has efficiently, feature accurately.

Summary of the invention

For solving the problems of the technologies described above, the invention provides a kind of intelligent type low-voltage power distribution network decompression power alarm terminal.

The present invention is mainly made up of single-chip microcomputer, AC power supplies module, lithium battery module, power transfer module, decompression detection module, and AC power supplies module is connected with single-chip microcomputer by power transfer module respectively with lithium battery module, for single-chip microcomputer provides power supply; Decompression detection module is some groups, is connected respectively by data wire with single-chip microcomputer, and decompression detection module adopts solid-state relay, distribution transformer low-voltage side outlet decompression situation is detected, and by data wire, information is sent to single-chip microcomputer; On single-chip microcomputer, by data wire, gsm module is set, completes the data interaction between Surveillance center or mobile phone.

Power transfer module can realize the uninterrupted conversion fast of 220V AC power and lithium battery power supply, after the AC power decompression or power-off providing, is converted to fast lithium battery module power supply is provided in AC power supplies module.

Preferably, between decompression detection module and single-chip microcomputer, photoelectric coupling unit for promoting inhibition is set.

Photoelectric coupling unit for promoting inhibition can be realized the electrical isolation of 220V observation circuit and single-chip microcomputer and other modules, prevents from altering electricity and burns terminal.

Adopt intelligent type low-voltage power distribution network decompression power alarm terminal of the present invention can realize Real-Time Monitoring and the real time alarm function to low-voltage network equipment decompression or power-off, when terminal monitoring has to low-voltage equipment (circuit) after a phase or heterogeneous decompression or power-off, can be in time by decompression or powering-off state, send warning message to default administrative staff (can many people).Adopt the present invention, can set up the real-time automation and intelligentification management to low-voltage network monitoring node, obtain in time power distribution network decompression power cut-off information, for promoting not outage management of power distribution network, provide field data the most promptly and accurately.

Brief description of the drawings

Fig. 2 is that terminal of the present invention is used winding diagram.

Embodiment

As shown in Figure 1, AC power supplies module is connected with single-chip microcomputer by power transfer module respectively with lithium battery module, for single-chip microcomputer provides power supply; Decompression detection module is 3 groups, is connected respectively by data wire with single-chip microcomputer, between decompression detection module and single-chip microcomputer, photoelectric coupling unit for promoting inhibition is set; Decompression detection module adopts solid-state relay, distribution transformer low-voltage side outlet decompression situation is detected, and by data wire, information is sent to single-chip microcomputer; On single-chip microcomputer, by data wire, gsm module is set, completes the data interaction between Surveillance center or mobile phone.

1, the each component function of terminal is described:

(1) .[AC power module]: for monitoring terminal provides 220V AC power.

(2) .[lithium battery module]: after 220V AC power decompression or power-off, for terminal provides uninterrupted power supply, sustainable work is more than 8 hours.

(3). [power transfer module]: the one, realize the uninterrupted conversion fast of 220V AC power and lithium battery power supply; The 2nd, for single-chip microcomputer and GSM communication module provide stable 5V DC power supply.

(4). [single-chip microcomputer]: the one, realize distribution transformer low-voltage side outlet A, B, C three-phase pressure loss situation, carry out 24 hours uninterrupted detections; The 2nd, by controlling gsm module, complete the data interaction between Surveillance center's (or personal mobile phone), in the time there is a phase or heterogeneous decompression or power-off, send in time Realtime Alerts information to equipment management personnel.
