Description
Technical field
The utility model relates to transformer, particularly relates to a kind of dry-type transformer temperature online monitoring system.
Background technology
Along with electricity need load constantly increases, the load centers such as downtown area, residential quarter, big-and-middle-sized factories and miness more and more go deep in city web area electric substation, and jumbo block supply dry-type power transformer obtains widespread use.Along with the raising of country to the environmental requirements such as degradation treatment of fire savety, the rear waste material of transformer operation life termination, dry-type transformer in the advantage aspect Environmental Safety, is more and more subject to users' welcome with it.
The safe operation of dry-type transformer and serviceable life, depend on to a great extent the safe and reliable of Transformer Winding insulation.Winding temperature makes to insulate destroyed over insulation tolerable temperature, be the one of the main reasons that causes transformer cisco unity malfunction, to the monitoring of transformer running temperature, is therefore very important.
At present, the method that dry-type transformer is carried out to temperature monitoring has a variety of, mainly comprises its temperature controller carrying, infrared temperature measurement device, optical fiber temperature-measurement device, active radio thermal detector etc.
Temperature controller main number shows, can not directly observe variation, and is arranged in on-the-spot complicated electromagnetic environment, controls complexity.
Infrared measurement of temperature is contactless temperature-measuring, is subject to environment and the interference of electromagnetic field around, and the space of dry-type transformer is very narrow and small in addition, cannot installation infrared temperature probe, and require measured point can in the visual field, there is no coverage, and surface clean is to guarantee accuracy.
1) characteristics such as fibre optic temperature sensor adopts fiber optic transmission temperature signal, and light transmitting fiber has excellent insulating property, yet optical fiber has easy to break, easily broken, non-refractory.Thereby after accumulation dust, easily cause optical fiber creeping discharge that insulativity is reduced.In addition, the cost of optical fiber temperature-measurement is also relatively high.
2) the common relatively large and frequent battery of changing of need of active radio temperature sensor size, system maintenance cost is higher.Meanwhile, battery is unsuitable for working under the condition of high temperature, particularly higher than the working environment of 150 ℃.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of and not only can realize electric insulation, and the dry-type transformer temperature online monitoring system of the data situation of displaying scene exactly.
The utility model is provided with dry-type transformer, Temperature sampler, thermometric main control terminal, long distance control system, and described dry-type transformer is provided with SAW temperature sensor, and described SAW temperature sensor is provided with the antenna of reception and emitting radio frequency signal; Described Temperature sampler is also provided with the antenna of reception and emitting radio frequency signal; Described long distance control system is connected with thermometric main control terminal by communication cable, and described thermometric main control terminal is connected with Temperature sampler by the wireless receiving module with antenna.
Described Temperature sampler can be provided with at least 1, and SAW temperature sensor also can be provided with at least 1.
Described SAW temperature sensor Real-time Collection dry-type transformer each phase and temperature unshakable in one's determination, after described Temperature sampler is processed, be sent to described thermometric main control terminal by the described wireless receiving module with antenna.
Described thermometric main control terminal is passed through the temperature information of dry-type transformer communication protocol and the described long distance control system interface of RS485 and standard.
SAW sensor adopts passive induction mode, without battery-operated, has reduced the maintenance cost that battery altering brings, and can not impact ecologic environment simultaneously.Wireless temperature sampling mode is without line in measured point or related support structure, between sensor and receiving equipment without electrical link, thereby realized high pressure isolation, support equipment safe operation.Passive wireless temperature sensor volume little and and collector between data wireless transmission, easy for installation flexibly.The price of SAW sensor is lower compared with other traditional thermometric modes, and meanwhile, the working method of passive and wireless makes the installation of native system, maintenance cost greatly reduce.
