Abstract
The invention discloses a short-circuit and ground fault remote real-time on-line monitoring system which is mainly composed of a short-circuit current sensor, a ground current sensor, a fault indicator, a hub and a GSM wireless data processor, wherein, the short-circuit current sensor and the ground current sensor are connected with the fault indicator, the fault indicator is connected with the hub by a wireless or wire mode, fault information which is collected by the short-circuit current sensor and the ground current sensor is transmitted to the hub, the hub sends the information to a GSM wireless public network after the information is processed by the GSM wireless data processor, and the information is transmitted by an SMS or GPRS mode. A fault patrol inspector can know the section and the specific position of a fault without the need of going to the scene and troubleshoot the fault in the power-off section at the first time by the monitoring system, the working efficiency is very high, and the loss of the production and the life caused by power outage can be reduced to the lowest level.
Description
Technical field:
The present invention relates to monitoring technical field, especially relate to technology in running electric wire is short-circuited and earth fault is monitored.
Background technology:
At present, China's economy is in the period of high speed development, all trades and professions such as industry, agricultural are to the demand surge of electric power, the excess load power supply that causes owing to shortage of electric power becomes universal phenomenon, and the consequence that the excess load power supply causes is very serious, such as cable short circuit, cause long power failure, even initiation fire or the like.How can very first time discovery accident, be on the scene and find the cable that breaks down, become the problem that presses for solution, people have found out a lot of ways, and designed various testing tools, but actual effect is limited, fails to tackle the problem at its root.
Traditional way is after the operator on duty receives the report of accident generation section, to be on the scene now, infers by the observation at scene, and judge it specifically is which electric cabinet goes wrong, trouble-shooting point piecemeal again, this mode need be wasted a large amount of time, and operating efficiency is very low.
The utility model content:
The objective of the invention is to the weak point that exists at prior art and a kind of short circuit and earth fault remote live on-line monitoring system are provided, it can lock the fault point accurately and real-time, thereby improves the operating efficiency of fixing a breakdown greatly.
For achieving the above object, monitoring system of the present invention is mainly by the short circuit current transducer, the earth current transducer, fault detector, hub, the gsm wireless data processor constitutes, wherein, the short circuit current transducer links to each other with fault detector with the earth current transducer, and be arranged on ring main unit in the electric power system, high voltage cable branch box, current acquisition point place in the high-tension switch cabinet circuit, fault detector links to each other with hub by wireless or wired mode, will by short circuit current transducer and earth current sensor acquisition to fault message be transferred to hub, by hub information is sent to the gsm wireless public network after via the gsm wireless data processor processes, transmit information in the mode of note or GPRS.
Described fault detector and hub can be the radio-frequency receiving-transmitting pattern.
Described fault detector can be with the RS-485 communication interface, and is connected by wired mode between the hub.
Described fault detector can be KML3 type fault detector, and is connected by wired mode between the hub.
Beneficial effect of the present invention is: by above-mentioned monitoring system, the fault personnel that patrol and examine do not use on-the-spot section and the particular location of knowing that promptly fault takes place, can the fault with the power failure section exclude in the very first time, operating efficiency is very high, can drop to production that causes because of power failure and life loss minimum.
