Technical field
The present invention relates to electric automatization field, particularly a kind of 35kV inlet wire of substation electriferous state alarm monitor.
Background technology
My company for a long time, does not all install 35kV electric power incoming line and carries out active and monitor and autoalarm.Over the years, my company 35kV power supply power-fail is all do not operated by electric substation's pulpit illuminating lamp, electrical equipment and the switch trip sound etc. or receive inquiry phone, again by observing the reometer of control flow and voltage table judges it is 35kV power supply power-fail, or inlet wire and the power down of main transformer circuit breaker trip.Power down accident diagnoses reaction velocity is slow, by judging, reporting, operating supervisor, recover electric power feeding time long, the life security of I ore deposit borehole operation worker of serious threat.Increase 35kV inlet wire power down automatic acousto-optic alarm device, 35kV power down can be judged in the very first time.
Summary of the invention
The object of the invention is to overcome the problems referred to above, a kind of 35kV inlet wire of substation electriferous state alarm monitor is provided.
For achieving the above object, the method that the present invention adopts is: a kind of 35kV inlet wire of substation electriferous state alarm monitor, comprise signal acquisition module, functional block selects module, signal output module, direct drive module and signal response module, described signal acquisition module comprises two ac contactor coil KM1 and KM2, ac contactor coil KM1 with KM2 be connected respectively 35kV electric power incoming line 512 and 517 with the transformer for electric substation's operating power, described functional block selects module to comprise a change-over switch, change-over switch is used for the switching between duty and inspecting state, described signal response module comprises signal lamp and direct current warning device, described direct drive module is described signal response module for power supply, described signal output module comprises normally opened contact and the normally closed contact of A.C. contactor, the normally opened contact of A.C. contactor is connected with direct drive module after connecting with signal lamp, and A.C. contactor normally closed contact is connected with direct drive module after connecting with change-over switch and direct current warning device.
Preferred as one of the present invention, described direct current warning device comprises dry cell, joins alarm module loudspeaker and flashing trafficator.
Beneficial effect:
Alarm monitor of the present invention can save the judgement time greatly, shortens the whole power down process time.Rapid reaction nature of occurence, sends sound and light alarm signal to operator on duty, directly judges nature of occurence, decrease analysis, the row's of looking into time of casualty, shorten incident processing procedure, the heavy economic losses that the accident of reducing is brought, avoiding gas exceeding limit, decreasing the impact on producing.Improve the ability that worker answers calamity, combats a natural disaster.Emergency operation is taked to recover full mine power supply in time.Restore electricity fast, ensure that the power supply of underground main drainage pump, ensure that the normal ventilation of each ventilating shaft, ensure that the life security of down-hole worker.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present invention;
Fig. 2 is circuit diagram of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, the present embodiment is implemented under premised on technical solution of the present invention, should understand these embodiments and only be not used in for illustration of the present invention and limit the scope of the invention.
Be illustrated in figure 1 35kV inlet wire of substation electriferous state alarm monitor of the present invention, comprise signal acquisition module, functional block selects module, signal output module, direct drive module and signal response module, described signal acquisition module comprises two ac contactor coil KM1 and KM2, ac contactor coil KM1 with KM2 be connected respectively 35kV electric power incoming line 512 and 517 with the transformer for electric substation's operating power, described functional block selects module to comprise a change-over switch, and change-over switch is used for the switching between duty and inspecting state; Described signal response module comprises signal lamp and direct current warning device; Described direct drive module is described signal response module for power supply; Described signal output module comprises normally opened contact and the normally closed contact of A.C. contactor, the normally opened contact of A.C. contactor is connected with direct drive module after connecting with signal lamp, and A.C. contactor normally closed contact is connected with direct drive module after connecting with change-over switch and direct current warning device.Direct current warning device comprises dry cell, joins alarm module loudspeaker and flashing trafficator.
As shown in Figure 2, for circuit diagram of the present invention, in figure, ac contactor coil KM1 and KM2 connects through the 380V electricity of 35kV power supply 512,517 inlet wire after transformer transformation respectively, direct current cabinet connects pilot lamp through KM1 normally opened contact, and for pilot lamp is powered, it is that pilot lamp is powered that direct current cabinet connects pilot lamp through KM2 normally opened contact, direct current cabinet connects audible-visual annunciator through KM1 normally closed contact, change-over switch, and direct current cabinet connects audible-visual annunciator through KM2 normally closed contact, change-over switch.
When 512,517 inlet wires are normal, ac contactor coil KM1 and KM2 connects, and KM1 normally opened contact, KM2 normally opened contact are closed, and two pilot lamp are all bright, represents that 512,517 inlet wires are normal.Now KM1 normally closed contact, KM2 normally closed contact disconnect, and audible-visual annunciator disconnects and not working.
When 512,517 inlet wire fault, ac contactor coil KM1 and KM2 disconnects, and KM1 normally opened contact, KM2 normally opened contact disconnect, and pilot lamp extinguishes, display fault.Now KM1 normally closed contact, KM2 normally closed contact close, and audible-visual annunciator is connected.Control alarming horn by alarm module, and flashing trafficator flashes.Realize ground transformer substation 35kV incoming power power down automatic sound-light alarm function.
