Abstract
The utility model relates to an on-line insulated monitoring device of power network operation equipment, belonging to the technical field of electric power. The on-line insulated monitoring device of power network operation equipment comprises a control display part, a high-precision micro-current sensor and a shielding twisted pair, wherein the control display part is installed on a switch-cabinet instrument door panel or in a secondary terminal room; the high-precision micro-current sensor is installed in a high-voltage cable room; and the high-precision micro-current sensor and the control display part are connected together through the shielding twisted pair. The on-line insulated monitoring device can effectively prevent, diagnose, alarm and avoid failure disasters, reduces the loss, and meanwhile reduces the maintenance cost, the failure rate and the outage time of the equipment.
Description
Technical field
The utility model relates to the power technology field, is specifically related to the apparatus insulated on-Line Monitor Device of a kind of operation of power networks.
Background technology
China's electric power industry development is very fast, recent years particularly is also annual electricity generating capacity entry time prostatitis all of installed capacity; But occupancy volume per person; Also come after many countries; From industrial or agricultural electricity consumption or the household electricity that develops rapidly, equally also can feel the deficiency of electric power supply, make great efforts to accelerate power construction for this reason; Maintenance makes makes good use of existing power equipment, just seems very necessary with the raising of guaranteeing development and national economy and people's lives.The method system of being continued to use in decades that regularly carries out preventive trial; Through updating of the numerous technician of China; Brought into play vital role for the safe operation of China's power equipment; But along with the raising of China's power equipment rated voltage, the increase of single-machine capacity, the variation of structure kind; Particularly the power equipment insulation ag(e)ing is a kind of irreversible process that power equipment is broken off relations and under running status, produced under certain extraneous factor effect, and its mechanism of action is extremely complicated, and the method for the preventive trial that insulate after original main dependence regularly has a power failure just seems very not enough.Need when not only testing to have a power failure, the more important thing is content of the test and method after original power failure, much be difficult to reflect really the insulation status of equipment under test under service condition.The domestic method that yet has some units to begin one's study and try out on-line monitoring does not have advanced detection technique and corresponding instrument but suffer from, so that is difficult to practicability.
The utility model content
The apparatus insulated on-Line Monitor Device of operation of power networks that the utility model technical matters to be solved is to provide a kind of state of insulation that can monitor high voltage alive equipment in real time and leakage current and leakage current to overflow functions such as warning.
The utility model technical matters to be solved adopts following technical scheme to realize,
The apparatus insulated on-Line Monitor Device of a kind of operation of power networks; It is characterized in that: comprise control display part, high precision low current sensor and Shielded Twisted Pair composition; Described control display part is installed on the switch cubicle instrument door face board or in the secondary terminals seed cell; It is indoor that described high precision low current sensor is installed in high-tension cable, and described high precision low current sensor couples together through Shielded Twisted Pair with the control display part.
The beneficial effect of the utility model is: the utility model can effectively prevent, diagnoses and alarm, and prevents the generation of fault property disaster, reduces loss, reduces maintenance cost simultaneously, lowers failure rate, reduces equipment idle time.
