Abstract

A kind of voltage fluctuation warning device, comprise toggle switch, power light, reset button, voltage relay, auxiliary reclay, normal opened contact, normally closed contact and alarm, device parts are linked together by series-parallel mode, when there is fluctuation in voltage, the alarm of its correspondence sends audible alarm, and such operator on duty just can judge which section bus breaks down in time, exactly, thus substantially increase operator on duty judge, in time, accident settlement exactly, shorten power off time, increase work efficiency.

Description

A kind of voltage fluctuation warning device

Technical field

The utility model relates to a kind of warning device, particularly a kind of voltage fluctuation warning device.

Background technology

Voltage fluctuation and power instantaneous fluctuation, mainly refer to instantaneous drop and the instantaneous power-off of line voltage.Instantaneous drop refers to that grid voltage amplitude reduces suddenly in a flash at certain because of certain reason; Instantaneous power-off refers to that line voltage was asked at certain a flash and is entirely zero suddenly.The reason of line voltage momentary fluctuation is a lot, such as, when electrical network be struck by lightning or lightning induction time, can instantaneous power-off be caused; The accident of power main aspect is also the main cause producing line voltage momentary fluctuation, and the line of electric force accident of 90% also can cause the instantaneous power-off of electrical network, affects network system.Usually cause electric power system voltage dip for above-mentioned reasons, the lighter causes process units to fluctuate, and severe one causes production line to stop, and causes heavy economic losses to enterprise.

But the warning device of equipment no-voltage fluctuation at present, operator on duty finds that the approach of voltage fluctuation often can only glimmer according to daylight lamp instantaneously, prison dish is checked meter or by linking up to relevant teams and groups, routine dispatching and obtain system voltage fluctuation information, the information obtaining voltage fluctuation is seriously delayed, can not treatment facility unusual condition in time, thus can not notify that user restores electricity in time, affect user and normally produce.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of voltage fluctuation warning device, in time, accident settlement exactly, shortens the moment that has a power failure, increases work efficiency.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of voltage fluctuation warning device, comprise from 10KV I, II section of system draws a road AC 220 V power supply supply warning device, connection button word switch ZK, the power supply instruction red light HD of warning device circuit one, the potential relay coil 1YJ of circuit two, with the normally closed contact of reset button 1TA and the coils connected in series of auxiliary reclay 1ZJ after the normally closed contact of the voltage relay 2YJ of circuit three is in parallel with the normal opened contact 1ZJ1 of auxiliary reclay 1ZJ, the normal opened contact 1ZJ2 of the auxiliary reclay 1ZJ of circuit four connects with alarm 2#JL, four sections of circuit in parallel are at 10KV I, II section of electric system low tension loop.

A kind of voltage fluctuation warning device, from 10KV III, IV section of system draws a road AC 220 V power supply supply warning device, connection button word switch ZK, the power supply instruction red light HD of warning device circuit one, the potential relay coil 2YJ of circuit two, with the normally closed contact of reset button 2TA and the coils connected in series of auxiliary reclay 2ZJ after the normally closed contact of the voltage relay 1YJ of circuit three is in parallel with the normal opened contact 2ZJ1 of auxiliary reclay 2ZJ, the normal opened contact 2ZJ2 of the auxiliary reclay 2ZJ of circuit four connects with 1#JL alarm, four sections of circuit in parallel are at 10KV III, IV section of electric system low tension loop.

The beneficial effects of the utility model are: overcoming operator on duty can not the deficiency of Timeliness coverage unit exception when routine work, so as in time, accident settlement exactly, shorten power off time, increase work efficiency.

Embodiment

Below in conjunction with accompanying drawing, structural principle of the present utility model and principle of work are described in further detail.

See Fig. 1, a kind of voltage fluctuation warning device, comprise from 10KV I, II section of system draws a road AC 220 V power supply supply warning device, connection button word switch ZK, the power supply instruction red light HD of warning device circuit one, the potential relay coil 1YJ of circuit two, with the normally closed contact of reset button 1TA and the coils connected in series of auxiliary reclay 1ZJ after the normally closed contact of the voltage relay 2YJ of circuit three is in parallel with the normal opened contact 1ZJ1 of auxiliary reclay 1ZJ, the normal opened contact 1ZJ2 of the auxiliary reclay 1ZJ of circuit four connects with alarm 2#JL, four sections of circuit in parallel are at 10KV I, II section of electric system low tension loop.

See Fig. 2, a kind of voltage fluctuation warning device, comprise from 10KV III, IV section of system draws a road AC 220 V power supply supply warning device, connection button word switch ZK, the power supply instruction red light HD of warning device circuit one, the potential relay coil 2YJ of circuit two, with the normally closed contact of reset button 2TA and the coils connected in series of auxiliary reclay 2ZJ after the normally closed contact of the voltage relay 1YJ of circuit three is in parallel with the normal opened contact 2ZJ1 of auxiliary reclay 2ZJ, the normal opened contact 2ZJ2 of the auxiliary reclay 2ZJ of circuit four connects with alarm 1#JL, four sections of circuit in parallel are at 10KV III, IV section of electric system low tension loop.

Principle of work of the present utility model is:

When 10KV I, II section of system voltage is normal, HD is bright for pilot lamp display red light, and 1YJ potential relay coil is charged, and its normally closed contact 1YJ opens; When system voltage fluctuates, 1YJ potential relay coil moment dead electricity, its normally closed contact 1YJ closes, and 2ZJ auxiliary reclay coil obtains electric, and its normal opened contact 2ZJ1,2ZJ2 are closed, and 1#JL alarm light stroboscopic is reported to the police, self-sustaining simultaneously.

In like manner: when 10KV III, IV section system voltage is normal, corresponding pilot lamp display red light HD is bright, and 2YJ potential relay coil is charged, and its normally closed contact 2YJ opens; When system voltage fluctuates, 2YJ potential relay coil moment dead electricity, its normally closed contact 2YJ closes, and 1ZJ auxiliary reclay coil obtains electric, and its normal opened contact 1ZJ1,1ZJ2 are closed, and 2#JL alarm light stroboscopic is reported to the police, self-sustaining simultaneously.

First operator on duty presses involution button and stops sound equipment, and then according to warning message, check the operation conditions of faulty section high-tension apparatus, after timely accident settlement, the very first time notifies that user restores electricity, and shortens customer outage hours.
