Description
Technical field
The utility model is related to a kind of power transformer wind-cooling heat dissipating control devices.
Background technology
The type of cooling of current major part 220kV and more than large-capacity power transformer is oil-immersed forced-air cool.Radiating
Fan is filled on device, utilizes temperature sensors for temperature sensor so as to start fan, air is made to accelerate flowing, is radiated whereby to increase
Ability.
The reliability service of power transformer plays a crucial role the operation and maintenance of substation, is not prevented from electric power change
Depressor generates heat in operation, and temperature is excessively high, cooling system can be set to cool down, at present large-capacity power Cooling Methods of Transformers
Using oil-immersed forced-air cool, radiated starting fan, cooled down using temp control switch.There is control essence in this control mode
Degree is not high, temp control switch is easily damaged, needs the deficiencies of frequent Maintenance and Repair, it is impossible to the efficient startup for realizing fan.
The content of the invention
The purpose of this utility model is to provide a kind of power transformer wind-cooling heat dissipating control device.
The utility model is realized using following technical scheme：A kind of power transformer wind-cooling heat dissipating control device, feature
It is：Including power supply, switch module and radiating module；The power supply is connected with switch module one end, the switch module other end with
Radiating module connects；The switch module includes contactor and the memory alloy spring with double-pass memory effect；Described dissipates
Thermal modules are power transformer radiator fan.
Further, the switch module is mounted on the top of power transformer body.
Further, a fuse is connected between the power supply and switch module.
Further, the power supply is AC power.
The control device of the utility model controls the start and stop of fan using the shape memory effect of memorial alloy,
Control accuracy, more efficient, quality is relatively reliable, operation and maintenance are more convenient, the service life cycle is long.
Description of the drawings
Fig. 1 is this practical functional block diagram.
Fig. 2 is utility model physical circuit schematic diagram.
Specific embodiment
Explanation is further explained to the utility model in the following with reference to the drawings and specific embodiments.
Referring to Fig. 1, the utility model provides a kind of power transformer wind-cooling heat dissipating control device, including power supply, switch
Module and radiating module.The power supply is connected with switch module one end, and the switch module other end is connected with radiating module；It is described to open
Closing module includes contactor and the memory alloy spring with double-pass memory effect；The radiating module dissipates for power transformer
Hot-air fan.The circuit diagram of one embodiment of the utility model is referring to Fig. 2.
Further, the switch module is mounted on the top of power transformer body.
Further, a fuse is connected between the power supply and switch module.
1 is power supply in Fig. 2, and 2 be fuse, and 3 be switch module, and 3-1 is memory alloy spring, and 4 be fan.
Power module is mainly that whole device provides AC power in the utility model, and switch module is mainly remembered by round trip
The memory alloy spring mechanism composition of effect, memory alloy spring mechanism include card slot and the round trip memory effect in card slot
The memory alloy spring answered, which deforms upon elongation when power transformer temperature reaches setting value, so as to connect circuit,
So that contactor (KM1) must be electric, so as to control the startup of fan, the effect of cooling is played.Shorten when temperature is less than setting value,
Circuit disconnects, and fan is out of service.
The radiating module is fan on radiator of power transformer body, and when startup increases power transformer
Heat dissipation.
The start and stop of fan, control accuracy, more efficient, matter are controlled using the shape memory effect of memorial alloy
Measure that relatively reliable, operation and maintenance are more convenient, the service life cycle is long.
The above are the preferred embodiment of the utility model, all changes made according to technical solutions of the utility model are produced
Function without departing from technical solutions of the utility model scope when, belong to the scope of protection of the utility model.
