Description
Technical field
The utility model is related to a kind of optical fiber temperature-measurement set spare fibre probe, especially one kind can improve the thermometric degree of accuracy and
The double fibre-optical probes of the transformer optical fiber temperature-measurement equipment of equipment operational reliability.
Background technology
Transformer optical fiber temperature-measurement equipment is set for transformer safety operation, and its structure is by optical fiber and optical fiber one end
The photoelectric conversion module to connect and the fibre-optical probe that connects with the optical fiber other end etc. are formed, by fibre-optical probe in transformer during use
Inside transformer coil assembly is connected to by flange port before putting into operation.The existing fibre-optical probe using fluorescence sunset glow effect is provided with ball
Shape probing shell, optical fiber is connected to probing shell（Optic fibre end is inserted in probing shell）, it is fixed with probing shell glimmering
Light luminescent material, optical axis are perpendicular to fluorescence radiation material surface（Incidence angle is zero）, in photoelectric conversion module be provided with
The vertical optical filter of optical axis, i.e., sending and receiving for light is carried out by an optical fiber and optical filter.When swashing transmitted by optical fiber
Light irradiation is encouraged in fluorescence radiation material, fluorescence radiation material absorbs luminous energy and enters excitation state from ground state, and energy level will occur for electronics
Transition phenomenon, along with emergent light during energy level transition（Fluorescence）, such as encourage luminous intensity to keep constant, then emergent light
Fluorescence sunset glow intensity is the monotropic function of temperature and is inversely proportional with temperature value that, after even if excitation light removes, fluorescence luminescent material is still
The luminescence phenomenon of a period of time can be maintained.Because existing optical fiber temperature-measurement equipment is to be carried out the transmission of light by an optical fiber and connect
Receive, therefore can only be controlled by controller by optical fiber alternate transmission excitation light and emergent light, there are the following problems：
1. temperature measurement accuracy can not be influenceed in the case where encouraging light irradiation by emergent light accurate delivery to photoelectric conversion module, and
Temperature measuring point is simultaneously discontinuous, it is impossible to which the running temperature of transformer is monitored in real time；
2. needing accurate control and distinguishing excitation light and emergent light, control difficulty is increased, reduce equipment operation can
By property.
The content of the invention
The utility model is to solve the above-mentioned technical problem present in prior art, proposes that one kind can improve thermometric standard
The double fibre-optical probes of the transformer optical fiber temperature-measurement equipment of exactness and equipment operational reliability.
Technical solution of the present utility model is：A kind of double fibre-optical probes of transformer optical fiber temperature-measurement equipment, there is probe
Housing, excitation optical fiber is connected to probing shell, fluorescence radiation material, the optical axis of the excitation optical fiber are fixed in probing shell
Angle between fluorescence radiation material surface normal is acute angle, reception optical fiber is connected to the probing shell, in the spy
The first reflecting surface and the second reflecting surface are additionally provided with casing, the emergent light of the fluorescence radiation material is anti-by the first reflecting surface
Reception optical fiber is reflexed to again after being mapped to the second reflecting surface.
The utility model can be respectively transmitted excitation light and emergent light, can be by emergent light accurate delivery extremely when encouraging light irradiation
Photoelectric conversion module, the precision of temperature survey is improved, while the running temperature of transformer can be monitored in real time；Without essence
Quasi- control optical fiber rotation transmission excitation light and emergent light, reduce control difficulty, improve equipment reliability of operation.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with brief description of the drawings specific embodiment of the present utility model.As shown in Figure 1：A kind of transformer optical fiber is surveyed
The double fibre-optical probes of warm equipment, there is probing shell 9 same as the prior art, and excitation optical fiber 3 is connected to probing shell 9,
Fluorescence radiation material 5 is fixed in probing shell 9, with prior art except that the optical axis and fluorescence radiation material of excitation optical fiber 3
Angle between the surface normal of matter 5（Incidence angle）For acute angle, also it is connected to probing shell 9 and is connect with what excitation optical fiber be arranged in parallel
Optical fiber 1 is received, the first reflecting surface 6 and the second reflecting surface 7, the first reflecting surface 6 and the second reflecting surface are additionally provided with probing shell 9
7 can use level crossing, be fixed on by support etc. on probing shell 9, its angle should ensure that the outgoing of fluorescence radiation material 5
Light 4 reflexes to reception optical fiber 1 again after reflexing to the second reflecting surface 7 by the first reflecting surface 6.Optical signal is sent by reception optical fiber 1
To photoelectric conversion module 8.
