Abstract
The utility model relates to a temperature reduction self-control device of a transformer, which belongs to the field of supporting devices of transformers. The temperature reduction self-control device of the transformer comprises a fan and a power supply of the fan, and is characterized by being provided with a thermometer and a relay, wherein the thermometer is arranged on the transformer, a contact point in the thermometer and a coil of the relay are connected in a control power supply in series, and a normally open contact of the relay and the fan are connected in the power supply in series. By arranging the fan which can be opened automatically for reducing temperature at 65 DEG C, the purpose of automatically stopping the fan can be achieved when the temperature of the transformer is reduced to 55 DEG C. Therefore, possible harm to the transformer due to manual operation can be reduced, electric power of the transformer can be saved, and the operation of the transformer is reliable after transformation.
Description
Technical field
The utility model provides a kind of transformer cooling self-con-tained unit, belongs to transformer corollary apparatus field.
Background technology
The cooling of transformer at present is still fan for cooling mostly, and the oil temperature of transformer influences with season and load variations thereof, the operator on duty in patrolling and examining according to the height of transformer temperature artificial start-stop fan.This traditional way has following shortcoming: 1, artificial start-stop fan, increased start-stop fan randomness, bring waste of electric energy thus, 2, might patrol and examine untimely because of the operator on duty, cause transformer temperature variation difference big, make iron core, coil, the high-low pressure porcelain vase of transformer, each seals mat and inner fastening means, insulation ag(e)ing damages to be quickened, and thus transformer is brought all harm.
The utility model content
According to above the deficiencies in the prior art, the technical problems to be solved in the utility model is: a kind of safe and reliable transformer cooling self-con-tained unit is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of transformer cooling self-con-tained unit, the power supply that comprises fan and fan, it is characterized in that: thermometer and relay are set, thermometer is arranged on the transformer, the coil of contact and relay is connected between the control power supply in the thermometer, and the normally opened contact and the fan of relay are connected between the power supply.
Thermometer is monitored the transformer temperature in real time, along with the rising of temperature, and the closing of contact in the table, relay invocation point adhesive normally opened contact, fan gets electric starting, begins cooling; When the transformer temperature reduces, relay electric-loss, electric fan stall.
Wherein preferred version is:
Described relay coil both sides pilot lamp in parallel, pilot lamp is connected with contact in the thermometer.After temperature raises, the luminous warning of pilot lamp.
Described thermometer both sides manual switch in parallel.Increase and manually boot fan for cooling.
The utility model transformer cooling beneficial effect that self-con-tained unit had is: by thermometer and relay are set, thermometer is arranged on the transformer, the coil of contact and relay is connected between the control power supply in the thermometer, the normally opened contact of relay and fan are connected between the power supply, realized the automatic control of transformer cooling fan, can guarantee that by being provided with 65 ℃ of fans open cooling, the self-braking purpose of fan when the transformer temperature drops to 55 ℃ automatically.Reduce the harm that manual operation might bring for transformer, saved electric power again, reliable through transforming the back, solved artificial many disadvantages according to temperature of oil in transformer start-stop fan.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model;
Wherein: contact HR, pilot lamp KM1, KM2, relay 1TA, 2TA, 1QA, 2QA, button in K1, K2, K3, the thermometer.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Embodiment 1:
As shown in Figure 1, thermometer is arranged on the transformer, and contact K2 is connected between control power supply A and the N phase with the coil of relay K M1 in the thermometer, and normally opened contact and the fan of relay K M1 are connected between the power supply.Relay K M1 coil both sides pilot lamp HR in parallel, pilot lamp HR connects with contact K1 in the thermometer.
Thermometer both sides manual switch in parallel, increase manually boots fan for cooling.
Manual switch comprises the contact of button 1TA, 1QA and relay K M1, and the contact of relay K M1 and button 1QA parallel connection are connected between control power supply A and the N phase with button 1TA then.
Contact K1 is set to 55 ℃ in the thermometer, and contact K2 is set to 65 ℃ in the thermometer.Along with the rising of temperature, its contact is closed one by one.
Original thermometer is common prior art in the utility model, its setting and use to industry technician and grasped.
Principle of work and use:
During use, thermometer is monitored the transformer temperature in real time, along with the rising of temperature reaches 55 ℃, and contact K1 closure in the thermometer, the luminous warning of pilot lamp HR.Temperature continues to raise, contact K2 closure in the thermometer, and relay K M1 invocation point adhesive normally opened contact, fan gets electric starting, begins cooling; When temperature was lower than 65 ℃, contact K2 disconnected in the thermometer, relay K M1 dead electricity, electric fan stall.Also can realize control by manual operation button 1TA and button 1QA.
Embodiment 2:
If the transformer heating is bigger, desk fan cooling efficient is not enough, needs to increase by second desk fan.
The power supply of control linkage second desk fan of relay K M2 is set.Relay K M2 connects with contact K3 in the thermometer.The manual switch that contact K3 parallel connection is made of the contact of button 2TA, button 2QA and relay K M2 in the thermometer.
When temperature reaches 65 ℃, first desk fan is opened, but heat radiation is not enough, when temperature continues to rise, manually or automatically starts second desk fan, to realize the purpose of cooling.
Claims (3)
1. transformer cooling self-con-tained unit, the power supply that comprises fan and fan, it is characterized in that: thermometer and relay are set, thermometer is arranged on the transformer, the coil of contact and relay is connected between the control power supply in the thermometer, and the normally opened contact and the fan of relay are connected between the power supply.
2. transformer cooling self-con-tained unit according to claim 1 is characterized in that: described relay coil both sides pilot lamp in parallel, pilot lamp is connected with contact in the thermometer.
