Description
Technical field
Spare fibre probe is set the present invention relates to a kind of optical fiber temperature-measurement, especially one kind can improve the thermometric degree of accuracy and equipment
The transformer optical fiber temperature-measurement equipment of operational reliability pair fibre-optical probes.
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 connected and the fibre-optical probe that connects with the optical fiber other end etc. are constituted, by fibre-optical probe in transformer when using
Inside transformer coil assembly is connected to by flange port before putting into operation.The fibre-optical probe of existing utilization 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., carry out sending and receiving for light 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 excitation luminous intensity keeps constant, then emergent light
Fluorescence sunset glow intensity is the monotropic function of temperature and is inversely proportional with temperature value, even if after excitation light is removed, 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 by controller control by optical fiber alternate transmission excitation light and emergent light, there are the following problems：
1. temperature measurement accuracy, and thermometric can not be influenceed under excitation light irradiation by emergent light accurate delivery to photoelectric conversion module
Point is simultaneously discontinuous, it is impossible to which the running temperature to transformer is monitored in real time；
2. needing accurate control with distinguishing excitation light and emergent light, control difficulty is increased, the reliable of equipment operation is reduced
Property.
The content of the invention
The present invention is that, in order to solve the above-mentioned technical problem present in prior art, proposition one kind can improve the thermometric degree of accuracy
And the transformer optical fiber temperature-measurement equipment of equipment operational reliability pair fibre-optical probes.
The present invention technical solution be：A kind of transformer optical fiber temperature-measurement equipment has probing shell with double fibre-optical probes,
Be connected to excitation optical fiber with probing shell, fix fluorescence radiation material in probing shell, the optical axis of the excitation optical fiber with it is glimmering
Angle between light luminescent material surface normal is acute angle, and reception optical fiber is connected to the probing shell, in the probe shell
Be additionally provided with the first reflecting surface and the second reflecting surface in vivo, the emergent light of the fluorescence radiation material by the first reflective surface to
Reception optical fiber is reflexed to after second reflecting surface again.
The present invention can be respectively transmitted excitation light and emergent light, can be by emergent light accurate delivery to photoelectricity when encouraging light irradiation
Modular converter, improves the precision of temperature survey, while can in real time be monitored to the running temperature of transformer；Without precisely controlling
Optical fiber rotation transmission excitation light and emergent light processed, reduce control difficulty, improve equipment reliability of operation.
