Abstract
The invention relates to a transformer substation terminal box and a mechanism box heating moisture-dispelling alarm device. The transformer substation terminal box comprises a heater (EH1) and an alternating-current wire feeding loop thereof, and is characterized in that a coil of a first time relay (KT1) is connected in series beside the heater (EH1); the two ends of the alternating-current wire feeding loop are connected in parallel with a coil of a second time relay (KT2); a pair of normally-open contacts of the first time relay (KT1) is connected in series with a normally-working indicating lamp (GL) and is connected with a direct-current power supply and the ground respectively; a pair of normally-closed contacts of the first time relay (KT1) is connected in series with a broken wire indicating lamp (RL) and is connected with the direct-current power supply and the ground respectively; moreover, a pair of normally-closed contacts of the second time relay (KT2) is connected in series with a power supply fault indicating lamp (YL) and is connected with the direct-current power supply and the ground respectively. The working state of an internal circuit loop is converted into acoustic-optical signals of an external visualized signal lamp and a buzzer, so that faults can be judged conveniently.
Description
Technical field
The present invention relates to a kind of terminal box of transformer substation and mechanism case heating drive damp warning device.
Background technology
The transformer station of electric system 220V and above generally all adopts outdoor open type to arrange, especially northern area cold wet in winter.Easily produce solidifying frost, icing phenomenon in terminal box, mechanism case, malfunction or the tripping of power equipment can be caused time serious, hidden trouble is caused to safe operation of power system.Therefore in terminal box, mechanism case, whether heating moisture separating device normally can run whether play safely very important effect to equipment, but traditional inspection method needs opener case, terminal chamber door one by one, and workload is huge, the at substantial time.To electric system variation, operations staff brings inconvenience.
Current transformer station checks that effective means that in terminal box, mechanism case, whether heating moisture separating device is working properly is exactly open that chamber door uses soon, hand is touched, the method for multimeter amount is carried out one by one, and not only workload is large, and easily causes the danger of scalding or getting an electric shock.
Summary of the invention
The object of this invention is to provide a kind of terminal box of transformer substation and mechanism case heating drive damp warning device, can enable operation maintenance personnel easily when not opening chamber door fast, prepare whether judge to heat moisture separating device in case by signal lamp and audible alarm system working properly, substantially increase the work efficiency of operation maintenance personnel.
Damp warning device is driven in a kind of terminal box of transformer substation and mechanism case heating, comprise well heater and exchange wire inlet loop, its special feature is: at the other coil being in series with very first time relay of described well heater, and the coil of second time relay is parallel with at interchange wire inlet loop two ends, wherein a pair normally open contact of very first time relay is connected with direct supply and ground after connecting with normal relay indicating light respectively, and a pair normally closed interlock of this very first time relay is connected with direct supply and ground after connecting with disconnect lamp respectively, a pair normally closed interlock of other second time relay is connected with direct supply and ground after connecting with power failure lamp respectively.
Wherein disconnect lamp is also in series with hummer.
Wherein power failure lamp is also in series with hummer.
Wherein normal relay indicating light, disconnect lamp and power failure lamp are installed in outside the outer or mechanism case of the terminal box of transformer station.
Apparatus of the present invention are for terminal box existing in transformer station, mechanism case heating moisture separating device easily damages and substantial amounts, the improvement spending plenty of time and manpower to carry out OOBA (out of box audit) one by one and carry out is needed in operation maintenance personnel current check process, terminal box after repacking, mechanism case heating moisture separating device is by circuit connection in series-parallel principle, service-strong AC relay group is transformed, by transformation, at original terminal box, on the basis of mechanism case heating moisture separating device, AC relay is installed additional by inside, do not installing the method for signal lamp and hummer, it is the sound and light signal of outside signal lamp and hummer intuitively by internal circuit loop works condition conversion, such operation maintenance personnel can when not opening chamber door, fast, judge that whether inner heating moisture separating device is working properly accurately.Apparatus of the present invention have the characteristics such as wiring is simple, reliable.Outdoor open type arranges that the inspection of terminal box of transformer substation, mechanism case heating moisture separating device all can adopt this device, not only improves operation maintenance personnel work efficiency, more can avoid the danger such as scald, electric shock because hand is touched, the conventional inspecting method of multimeter amount causes.
Accompanying drawing explanation
Accompanying drawing 1 is circuit theory diagrams of the present invention;
Accompanying drawing 2 is circuit theory diagrams of the present invention.
Embodiment
As Fig. 1, shown in 2, the present invention is that damp warning device is driven in a kind of terminal box of transformer substation and mechanism case heating, comprise well heater EH1 and exchange wire inlet loop, at the other coil being in series with very first time relay K T1 of described well heater EH1, and the coil of the second time relay KT2 is parallel with at interchange wire inlet loop two ends, wherein a pair normally open contact of very first time relay K T1 is connected with direct supply and ground after connecting with normal relay indicating light GL respectively, and a pair normally closed interlock of this very first time relay K T1 is connected with direct supply and ground after connecting with disconnect lamp RL respectively, a pair normally closed interlock of other second time relay KT2 is connected with direct supply and ground after connecting with power failure lamp YL respectively.
Clearly, the above-mentioned time relay can be used alone, also can with contactor with the use of, namely with the coil that the contact of the time relay carrys out control contactor obtain, dead electricity, thus play time-lag action, reduce misoperation as far as possible.
Wherein disconnect lamp RL is also in series with hummer, and power failure lamp YL is also in series with hummer.Hummer, normal relay indicating light GL, disconnect lamp RL and power failure lamp YL are installed in outside the outer or mechanism case of the terminal box of transformer station in addition.
Using method of the present invention and principle of work are:
When well heater EH1 obtains electric normal work, the coil of very first time relay K T1 also electric, a pair normally open contact of very first time relay K T1 closes, and normal relay indicating light GL lights, and prompting normally works; After after well heater EH1 dead electricity stops, the above-mentioned normally open contact of very first time relay K T1 disconnects, and normal relay indicating light GL extinguishes, and a pair normally closed interlock of very first time relay K T1 then closes, disconnect lamp RL is become from extinguishing and lights, prompting well heater EH1 broken string; When after interchange wire inlet loop power-off, the coil losing electricity of the second time relay KT2, a pair normally closed interlock of the second time relay KT2 is become closed from disconnection, power failure lamp YL is become from extinguishing and lights, prompting power fail.
Therefore staff's duty that outer or mechanism case observes normal relay indicating light GL, disconnect lamp RL and power failure lamp YL outward at terminal box can judge, when certain disconnect lamp RL and power failure lamp YL lights, hummer also can start to pipe simultaneously.
Clearly, the time delay of the time relay can be determined voluntarily, such as, be set to 3s, can reduce misoperation.
