Description
Technical field
The utility model relates to automatic monitoring and the warning device that a kind of large-scale dc motor water-cooling system is leaked, and belongs to large-scale dc motor malfunction monitoring equipment technical field.
Background technology
Large-scale dc motor is the motive power outputting apparatus that various types of production plants generally use, and because of its excellent properties in speed governing on a large scale, has obtained using widely in all kinds of industrial and mining enterprises, and its power is generally at 200 kilowatts to 2000 kilowatts.The corresponding self-heating of powerful output is the major defect of large-scale dc motor, large-scale dc motor all adopts water-cooled and the air-cooled type of cooling that combines at present, wherein hydrocooler places in the confined space between motor top air inlet and the air outlet, recirculating air is taken away the recirculated water of heat in refrigeratory is cooled device that motor produces, thereby plays the effect to the motor cooling.Because recirculated water has certain corrosivity, refrigeratory is behind the work certain hour, leakage accident in can taking place, refrigeratory is in the confined space again in addition, the recirculated water of its leakage enters motor internal by air inlet and the air outlet on motor top, cause insulating motor coil to be destroyed, and cause the burn-down of electric motor accident.Because the disguise of this accident of generation and sudden, patrol to equipment and to cause very big difficulty, up to the present, all there be not a kind of automatic monitoring and warning device that the large-scale dc motor water-cooling system is leaked that be used for specially detecting both at home and abroad, therefore, a kind of automatic monitoring and warning device that can fast detecting large-scale dc motor water-cooling system leaks of design seems particularly important.
The utility model content
Technical problem to be solved in the utility model provides a kind of large-scale dc motor water-cooling system leakage inspector, and this device does not need manual patrol, can detect water leakage fault and warning in time rapidly and sensitively automatically and cut off device power supply (DPS).
The technical scheme that solves the problems of the technologies described above is:
A kind of large-scale dc motor water-cooling system leakage inspector, it is made up of Humidity Detection plate, detection head, auxiliary reclay, alarm, direct supply, the Humidity Detection plate is dull and stereotyped for insulation, the Humidity Detection plate is placed on the bottom in the direct current generator, detection head is two metal bare conductors, two detection heads are fixed on the plate face of Humidity Detection plate, one end of a detection head is connected with direct supply, the other end is vacant, one end of another detection head is connected with auxiliary reclay, the other end is vacant, and a pair of normally open contact of auxiliary reclay is connected with alarm.
Above-mentioned large-scale dc motor water-cooling system leakage inspector, the parallel placement of metal bare conductor of described two detection heads, adjacent spaces is 2-5mm.
Above-mentioned large-scale dc motor water-cooling system leakage inspector, a pair of normally closed interlock of described auxiliary reclay are connected in the direct current generator protection loop of direct current generator.
Useful result of the present utility model is:
When the utility model leaks in the direct current generator water-cooling system; water droplet drops on the Humidity Detection plate; insulation gap between two detection heads is connected by water; two detection head conductings; start the auxiliary reclay adhesive immediately; auxiliary reclay normally open contact closure; alarm equipment alarm; the auxiliary reclay normally closed interlock disconnects; direct current generator protection loop would trip; make direct current generator withdraw from the powered operation state rapidly, thereby avoided making the motor winding insulation destroy the generation of burning the motor accident because of water leakage of cooler.The utility model performance height simple in structure, easy to use, sensitive, protection are reliable, and need not artificial monitoring, have solved the problem that does not detect the specialized equipment that the large-scale dc motor water-cooling system leaks.
