Description
[technical field]
The utility model relates to a kind of power domains, more particularly to a kind of fibre optic temperature sensor that is used for directly to monitor oil immersion
When formula inside transformer temperature, fibre optic temperature sensor is penetrated through the optics outside optical signal transmission to transformer by this part
Device.
[background technique]
Transformer is one of the equipment of most critical in electrical transmission net, its service life and stability directly affects entire electric power
Net, transformer are divided into dry-type transformer and oil-immersed transformer according to the difference of the type of cooling.It is cold due to oil-immersed transformer
High-efficient, insulation performance is excellent, in field of power transformation using more and more.In equipment operation, some electric energy is converted to heat
Can, it will lead to the mild winding temperature of interior oil and increase, oil temperature and winding overheat not only result in insulation performance attenuating, accelerate device
Aging influences service life in turn, and the accident as caused by the hot-spot of winding at home and abroad has generation.So becoming
The running temperature monitoring of depressor gradually obtains the attention and close attention of design of transformer person and user, inside transformer temperature
Spending monitoring system has been essential a part in transformer itself core component；
Since inside transformer is a strong magnetic environment, the signal of temperature sensor cannot be conducted using electric signal, at present
Optical signal is used, an optical signal is issued to tested point, returns to the variation of optical signal using demodulation to calculate tested point
Temperature；The cavity for placing transformer oil is the cabinet being completely closed, and be divided to two kinds to the monitoring of its temperature: one is will be warm
Degree sensor is placed on monitoring on the outside of cabinet, and another kind is to place it in box house monitoring；It is carried out in fuel tank internal
Directly monitoring is undoubtedly most direct most effective way, since temperature sensor is and to solve analyzer in transformer in fuel tank internal
Outside, leakproofness, pressure-resistant performance when the key technology point of this monitoring mode is temperature sensor and the perforation of fuel tank external connection
And stability.
Component inside and outside connection perforation oil tank of transformer is called in the industry transfer panel, he is that a centre is provided with temperature biography
Sensor interface, pinboard surrounding are fixed by multiple screws with oil tank of transformer, and the contact surface of the two is provided with sealing ring, passes through
The locking of fastening screw compresses sealing ring so that the two is fully sealed, due to the powerful coupling mechanism force of fastening screw, this sealing side
Formula is ideal and stablizes, and the approval obtained in the industry becomes general connection type, but due to the interface of optics through device
Mating surface is more, precision requirement is high, device size is small, difficulty of processing is big, becomes the weak spot in entire temperature monitoring system
With key problem in technology point.
In the prior art, the sealing means of optics through device have following several:
With patent of invention (patent No.: CN105675167A), utility model patent (CN207199446U) and utility model
Patent (patent No.: CN205958142U) is to be fixed on pinboard after empty bolt and seal washer cooperation in the use one of representative
On, an optical fiber is fixed with epoxy resin inside interior sky bolt, optical fiber is docked with external sensor using welding mode.This mode
Whole optical fiber is directly fixed on inside metal bolts with epoxy resin, is expanded with heat and contract with cold in actual use since material is different
Coefficient is easy to cause optical fiber to be even broken in bolt internal injury, but can not reprocess, and can be caused due to the bad of optical fiber
Need to disassemble entire transformer, and inside and outside connection optical fiber is transferred without adapter, debugs and reprocess inconvenience.
By patent of invention (patent No.: CN106340372A) be representative sealing is encrypted using hollow bolt in a manner of by light
It learns through device to be fastened on pinboard, a both ends is fixed by sealant inside hollow bolt and have done fine gtinding with optical fiber
Ceramic insertion core, lock pin two sides fix two adapters, by two adapters and a ceramic insertion core by temperature sensor into
The inside and outside connection of row, this mode is relatively reasonable, but hidden danger point is whether the sealant of fixation hollow bolt and ceramic insertion core seals and fill
Divide and whether anti-pressure ability is enough.
