Description
Technical field:
The utility model relates to thermometer technical fields, and in particular to a kind of high factory's change oil surface temperature meter of novel combination type.
Background technique:
In order to meet power plant's oil-immersed transformer running temperature detection requirement, it is necessary to install oil surface temperature meter to it.With
Higher and higher to generating equipment safety, reliability requirement, the former capillary theory temperature on oil-immersed transformer is in respect of following
Some drawbacks: 1, former capillary theory thermometer need to be sent to provincial unit and test, and easily delay maintenance duration；2, raw wool tubule
Integral replacing is needed inside principle thermometer when faulty or defect, is spent larger；Therefore former capillary theory oil surface temperature meter is just
Benefit, reliability do not adapt to Developing requirement increasingly.And at high cost, measurement temperature distortion situation happens occasionally, seriously
Influence transformer station high-voltage side bus safety.
Utility model content:
The prior art is difficult to meet the needs of people, and to solve the above problems, the utility model proposes one
The high factory of kind novel combination type becomes oil surface temperature meter.
To achieve the above object, the utility model provides the following technical solutions: a kind of high factory's change pasta temperature of novel combination type
Degree meter, including temperature probe, temperature probe hole and temperature controller, it is characterised in that: thermometric is equipped in the temperature probe hole
Probe, the temperature probe are connect by conducting wire with temperature controller.
Preferably, the temperature controller uses DCS control system, is equipped with several pairs of electronic switches in temperature controller,
And temperature controller front is set there are two display screen, the display screen bottom is equipped with police instruction corresponding with electronic switch
Lamp, the alarm lamp bottom are equipped with several corresponding regulation buttons.
Further, the temperature controller is mounted on high factory and becomes in control cabinet.
Further, the display screen, electronic switch, alarm lamp and regulation button are connect with DCS control system.
Preferably, the temperature probe uses PT100 temperature probe, and the temperature probe hole is using former capillothermometer
Temperature probe hole.
Compared with prior art, the utility model has the beneficial effects that
1, strong antijamming capability, low cost and durability are good；
2, design is simple, and maintenance, maintenance are convenient, can be individually replaced accessory, save money, in former capillary theory thermometer
Integral replacing is needed when portion is faulty or defect, is spent larger；
3, verification is convenient, and former capillary theory thermometer need to be sent to provincial unit and test, and easily delays maintenance duration, newly
The high factory of type combined type, which becomes in oil surface temperature meter factory, can both be verified；
4, the high factory of novel combination type becomes oil surface temperature meter can carry out any operation at runtime, such as setting alarm temperature,
Fan operating temperature etc. can preferably adapt to live operation demand.Former capillary theory thermometer is after high factory becomes operation, no
It can be carried out any operation setting；
5, distortion situation when meter measurement can be reduced taking human as temperature-compensating is carried out, allows measurement temperature closer to reality
Temperature.
The design operation is simple, and comprehensive practical is strong, use easy to spread.
Detailed description of the invention:
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the temperature controller schematic view of the front view of the utility model；
In figure: 1- temperature probe hole, 2- temperature probe, 3- conducting wire, 4- temperature controller, 5- regulation button, 6- alarm refer to
Show lamp, 7- display screen.
Specific embodiment:
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Embodiment 1, a kind of high factory's change oil surface temperature meter of novel combination type, including temperature probe 2, temperature probe hole 1 and temperature
Controller 4 is spent, temperature probe 2 is equipped in the temperature probe hole 1, the temperature probe 2 passes through conducting wire 3 and temperature controller 4
Connection.
The temperature controller 4 uses DCS control system, and several pairs of electronic switches 8, and temperature are equipped in temperature controller 4
Degree 4 front of controller is set there are two display screen 7, and 7 bottom of display screen is equipped with alarm lamp corresponding with electronic switch 4
6,6 bottom of alarm lamp is equipped with several corresponding regulation buttons 5.
The temperature controller 4 is mounted on high factory and becomes in control cabinet.
The display screen 7, electronic switch 8, alarm lamp 6 and regulation button 5 are connect with DCS control system.
The temperature probe 2 uses PT100 temperature probe, and the temperature probe hole 1 is using raw wool capillary temperature measurement temperature
Probe hole.
The utility model becomes based on oil surface temperature by the high factory of novel combination type, and when in use, the high factory of novel combination type is become
Oil surface temperature meter is mounted in high factory's change, and PT100 temperature probe is mounted in former capillary theory thermometer temperature probe hole, temperature
Degree controller is mounted on high factory and becomes in control cabinet；It is defeated that the resistance signal that PT100 temperature probe is measured is converted into 4-20mA signal
Out to DCS, while it being integrated with 4 pairs of electronic switches in temperature controller, can be set and act at different temperatures, to realize height
Factory, which becomes the high alarm of oil surface temperature and other control functions, temperature controller front, to be had 2 display windows, can show current temperature
Degree, and parameter setting can be carried out when high factory becomes and runs, there are 4 alarm lamps below display screen, operations staff is facilitated to patrol
Apparent time finds temperature alarming in time.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
