Background technique
Existing transformer oil temperature control device is equipped with the copper body with inner cavity, has catch bar, copper intracoelomic cavity in the front end of copper body
It is communicated by sensing catheter (capillary) with temperature sensing package, is filled in the sealing system that temperature sensing package, sensing catheter and copper body are constituted
Temperature sensing medium.When measuring transformer oil surface temperature, temperature sensing package is placed in transformer top-oil temperature thermometric blind pipe, temperature sensing package is felt
The temperature answered changes the volume of temperature sensing medium therewith, and volume variable drives catch bar to generate a corresponding displacement, to
Indicate tested oil surface temperature.There is following problems:
1. response speed is slow
Temperature sensing package, sensing catheter and copper body make the heat loss of temperature measuring point, cause heat balance time long, in addition inside copper body
Pressure and external pressure also take a long time to can be only achieved balance, therefore response speed is slower；
2. measurement accuracy by the factors such as environment temperature, atmospheric pressure, capillary transmitting range and mechanical original part influenced compared with
Greatly, accuracy of measurement is reduced.
3. the element in sealing system is difficult to repair, once and copper body damages, internal liquid, gas are revealed,
Temperature controller is directly resulted in scrap.
Optical fiber temperature-measurement has been applied to multiple fields, is made of optical fiber temperature measurement host, temperature-measuring optical fiber and fiber optic temperature measuring probe, tool
Have structure simple, fast response time, accuracy and high reliability, still, due to transformer structure and use ring
The particularity in border, there are no the relevant reports that optical fiber temperature-measurement is applied to temperature of oil in transformer detection so far.
Summary of the invention
The utility model be in order to solve above-mentioned technical problem present in the prior art, provide a kind of fast response time,
The transformer oil temperature control device based on optical fiber temperature-measurement of accuracy and high reliablity.
The technical solution of the utility model is: a kind of transformer oil temperature control device based on optical fiber temperature-measurement has optical fiber survey
Warm host, the optical fiber temperature measurement host are connected by temperature-measuring optical fiber with fiber optic temperature measuring probe, are surveyed in optical fiber temperature measurement host to optical fiber
It is successively cased with metal hose on the optical fiber of temperature probe, draws long tube and optical fiber protection cover, the metal hose and drawing leads between long tube
It crosses the fixing piece for being fixed on metal hose end and being fixed on and draws the joint screw thread of long pipe end and connect；It is described draw be socketed on long tube
There is installation screw, be connected to installation nut with installation screw external screw thread, installing between screw and installation nut has the first cushion rubber, institute
Stating installation nut lower end has external screw thread for connecting with transformer thermometric blind pipe, upper end to have a circle boss, below the boss
It is fixed with gasket；Optical fiber protection cover lower end internal screw thread is connected with the cock body being structure as a whole with temperature-measuring optical fiber, cock body with
There is the second cushion rubber between optical fiber protection cover, it is anti-to be connected with the netted probe outside fiber optic temperature measuring probe with optical fiber protection cover lower end
Shield.
Fiber optic temperature measuring probe can be fixed in transformer top-oil temperature thermometric blind pipe by the utility model by installation nut,
Installation is simple, can install at any time, without the preset fibre-optical probe before transformer dispatches from the factory；Good airproof performance, can prevent rainwater etc. into
Enter in temperature of oil in transformer thermometric blind pipe；Safety is good, improves optical fiber and probe use reliability；Optical fiber temperature-measurement is given full play to ring
Answer fast speed, accuracy and high reliability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
The transformer oil temperature control device based on optical fiber temperature-measurement of the utility model, it is same as the prior art as shown in Figure 1:, have
Optical fiber temperature measurement host 1, optical fiber temperature measurement host 1 are connected by temperature-measuring optical fiber 2 with fiber optic temperature measuring probe 3, different from prior art institute
Be successively to be cased with metal hose 4 on the optical fiber 2 of optical fiber temperature measurement host 1 to fiber optic temperature measuring probe 3, draw long tube 5 and optical fiber is anti-
Shield 6, metal hose 4 use coiled pipe, and drawing long tube 5 can be used stainless steel tube, and the fixing piece 7 that 4 end of metal hose is fixed with draws
5 end of long tube is fixed with connector 8, fixing piece 7 and 8 threaded engagement of connector by screw 18, is secondary protection, can be shunk with waterproof
Pipe tightens 4 hose of part metals on 7 top of fixing piece；Draw and be socketed with installation screw 9 on long tube 5, with installation 9 external screw thread of screw
Be connected to installation nut 10, installing between screw 9 and installation nut 10 has the first cushion rubber 11, installation 10 lower end of nut have for
External screw thread 12 that transformer thermometric blind pipe connects, upper end have a circle boss 13, and boss 13 is fixed with gasket 14 below；Optical fiber is anti-
