According to the cooling system of the dry-type transformer, every cooling fan runs independently without interfering one another, and the running state of the whole transformer cannot be influenced even when one or several cooling fans fail, thereby providing an excellent cooling environment for the dry-type transformer.
Description
Technical field
The utility model belongs to electric equipment air cooler control system technical field, relates in particular to a kind of dry-type transformer cooling system.
Background technology
In manufacturing enterprise, power transformer comparison in equipment is many, and the impact of transformer simultaneously clearly, due to according to the difference of transformer load, the degree of heat that transformer there will be in running is just different, and these heats shed not in time, can occur a series of fault by transformer.For transformer can move normally, transformer cooling system has: oil cooling system and air cooling system; Oil cooling system is for oil-filled transformer, and air cooling system is usually used in dry-type transformer.The quality of the cooling system of transformer is determining the quality of transformer itself, also determines the useful life of transformer simultaneously.
At present, the power transformer that domestic production enterprise is used mostly is dry-type transformer, and it is cooling that dry-type transformer cooling undertaken by cross-ventilation, and dry-type transformer cooling system device structure is simple, cheap, practicality is stronger, and simple and reliable checkout gear.When but a cooling device in current dry-type transformer cooling system breaks down, will affect whole transformer cooling system, thereby will make whole transformer temperature raise and shut down, for production unit, can bring unnecessary economic loss.
Utility model content
Technical problem to be solved in the utility model is for shortcoming of the prior art, to provide each cooling fan of a kind of dry-type transformer to carry out the dry-type transformer cooling system of controlling along separate routes.
For solving technical problem of the present utility model, adopt following technical scheme:
A kind of dry-type transformer cooling system, comprise some cooling fans and control circuit, described cooling fan is arranged on the bottom of dry-type transformer, described control circuit comprises cooling fan way circuit, DN47 2P 10A circuit breaker and some DN47 2P 5A circuit breakers, described cooling fan way circuit is connected with dry-type transformer intelligent controller power supply terminal, described DN47 2P 10A circuit breaker is that cooling fan total power switch is located on cooling fan way circuit, described DN47 2P 5A circuit breaker is connected with cooling fan respectively, described some DN47 2P 5A circuit breakers are connected in parallel on cooling fan way circuit.
Described cooling fan is 6, and described DN47 2P 5A circuit breaker is 6.
Signalization indicator light on described cooling fan.
Described 6 DN47 2P 5A circuit breakers are arranged on the temperature indicator side of dry-type transformer by insulating material bakelite plate.
The dry-type transformer cooling system that the utility model provides, cooling fan electrical control is directly separated from intelligent transformer controller, and the intelligent controller of transformer does not participate in the control of cooling fan, only detects and show the operating temperature of transformer.Cooling fan running status is independently, and the state of each cooling fan is independent of each other, even if one or several cooling fan breaks down, also can not affect the whole running status that affects transformer, can provide better cooler environment to dry-type transformer.In manufacturing enterprise field, guaranteed the stable operation of dry-type transformer, reduced unnecessary economic loss simultaneously, this device adaptability is stronger, has price advantage, and can adapt to various working conditions, and practicality is very strong.This device electrical configurations is simple, and maintainable strong, maintenance is very little, and reliable.
Accompanying drawing explanation
Fig. 1 is the utility model electric drawings.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, a kind of dry-type transformer cooling system, comprises 6 cooling fans and control circuit, and cooling fan 4 is fixed on the bottom of dry-type transformer.Control circuit comprises 3,1 DN47 2P 10A circuit breaker 1 of cooling fan way circuit and 6 DN47 2P 5A circuit breakers 2, and these circuit breakers are all fixed on the power supply disks of cooling fan 4.Cooling fan way circuit 3 is connected with dry-type transformer intelligent controller power supply terminal, 1 DN47 2P 10A circuit breaker 2 is arranged on cooling fan way circuit 3 for cooling fan total power switch, 6 DN47 2P 5A circuit breakers 2 are connected with 6 cooling fans 4 respectively, and 6 DN47 2P 5A circuit breakers 2 are connected in parallel on cooling fan way circuit 3.In order to understand intuitively the state of cooling fan 4, can be furnished with signal lamp for each cooling fan 4.On insulating material bakelite plate, be fixed wtih 6 DN47 2P 5A circuit breakers 2, the feed cable of each cooling fan 4 lays independent cabling.
A kind of dry-type transformer cooling system that the utility model provides, mainly to utilize the independent thought of controlling of cooling fan 4, the electrical control of cooling fan 4 is directly separated from intelligent transformer controller, the intelligent controller of transformer does not participate in the control of cooling fan, only detects and show the operating temperature of transformer.Thereby cooling fan 4 running statuses are independently, the state of each cooling fan 4 is independent of each other, and cooling fan 4 can provide better cooler environment to dry-type transformer simultaneously, and the fault of cooling fan does not affect the running status of transformer.This control device principle is simple, and usability is stronger, and daily spot check maintenance workload is little, reliable.
Above-described is only preferred embodiment of the present utility model, does not limit to the utility model.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model, can also make other equivalent modifications and improvement, all can realize the purpose of this utility model, all should be considered as protection range of the present utility model.
