Abstract
The invention relates to an oil level monitoring and warning device for an oil conservator special for a transformer. The oil level monitoring and warning device is mainly characterized by comprising a light source emitter, a light source receiver, a photovoltaic conversion unit and a warning unit, wherein the light source emitter and the light source receiver are arranged in the oil conservator special for the transformer, the photovoltaic conversion unit is connected with the light source receiver, and the warning unit is connected with the photovoltaic conversion unit; the light source emitter is installed on the inner wall of the oil conservator and located above the oil level in the oil conservator; the light source receiver is installed on the inner wall, opposite to the light source emitter, of the oil conservator and located below the oil level in the oil conservator; the light source emitter irradiates a light beam of an emitting point to the light source receiver on the other side of the oil conservator at a certain angle. The oil level monitoring and warning device is reasonable in design; according to the refraction principle of light on an interface between gas and oil in the transformer, the oil level of the oil conservator in the transformer is reflected; meanwhile, according to the photovoltaic conversion principle, optical signals are converted into electric signals, and then the electric signals are output, so that the warning function is achieved; the oil level monitoring and warning device has the advantages of being safe and reliable in detection, accurate in testing result, easy and convenient to operate, high in anti-interference capacity and the like.
Description
Technical field
The invention belongs to transformer technology field, the special oil pillow oil level monitoring alarm of especially a kind of transformer.
Background technology
Transformer oil is as the main insulating material of oil-filled transformer, and its number in transformer determines that whether transformer insulation state is good.At present, the oil level detection of the special conservator of transformer is also confined to make an inspection tour personnel's visual inspection, and, because the phenomenon of bite often occurs oil level vernier, can not accurately reflect the truth of oil level.Therefore, in the urgent need to a kind of for helping tour personnel to find intuitively and accurately installation for transformer oil level situation and the equipment of alarm.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of transformer special oil pillow oil level monitoring alarm, solved the problem that prior art can not the special oil pillow oil level of visual inspection transformer and reported to the police.
The present invention solves its technical matters and takes following technical scheme to realize:
The special oil pillow oil level monitoring alarm of a kind of transformer, comprises the photoelectric conversion unit that the light source emitter that is arranged in the special conservator of transformer is connected with light source receiver and with light source receiver, the alarm unit being connected with photoelectric conversion unit; Described light source emitter is arranged on the inwall of the special conservator of transformer and is positioned at the pasta top of conservator, light source receiver is arranged on the special conservator inwall of transformer on light source emitter opposite and is positioned at the pasta below of conservator, light source emitter at an angle by launching site light beam irradiates to the light source receiver of conservator opposite side.
And described alarm unit adopts light emitting diode.
Advantage of the present invention and good effect are:
The present invention is arranged in conservator relative with light source receiver light source emitter, utilize the refraction principle of light at gas and transformer oil interface, reflect the oil level state of transformer oil in conservator, utilize photoelectricity transformation principle simultaneously, light signal is converted to electric signal output, realize warning function, have and detect safe and reliable, the advantage such as test result is accurate, easy and simple to handle, antijamming capability is strong, realized body Buchholz relay failure cause fast, reliably investigated to function.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is monitoring, alarming theory diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is further described:
The special oil pillow oil level monitoring alarm of a kind of transformer, as shown in Figures 1 and 2, comprise the photoelectric conversion unit that the light source emitter 1 that is arranged in the special conservator 2 of transformer is connected with light source receiver 4 and with light source receiver, the alarm unit being connected with photoelectric conversion unit.Described light source emitter is arranged on the inwall of the special conservator of transformer and is positioned at pasta 3 tops of conservator, light source receiver is arranged on the special conservator inwall of transformer on light source emitter opposite and is positioned at the pasta below of conservator, light source emitter and at an angle (as 30 degree) are fixed on a side of conservator, and launching site light beam is to the light source receiver of conservator opposite side.When light source emitter irradiates pasta at an angle, refraction principle according to light at gas and transformer oil interface, transformer oil and the air interface place generation refraction angle of light source in conservator, therefore, just can identify the variation of oil level in conservator by the variation of light source receiver reception luminous energy.Described light source receiver is connected successively with photoelectric conversion unit and alarm unit, and photoelectric conversion unit is converted to voltage signal output for the light signal that light source receiver is received, and amplifies output; Alarm unit adopts light emitting diode, and in the time that voltage exceedes certain threshold value, flicker is reported to the police, and facilitates operations staff to make an inspection tour.
It is emphasized that; embodiment of the present invention is illustrative; instead of determinate; therefore the present invention includes and be not limited to the embodiment described in embodiment; every other embodiments that drawn by those skilled in the art's technical scheme according to the present invention, belong to the scope of protection of the invention equally.
Claims (2)
1. the special oil pillow oil level monitoring alarm of transformer, is characterized in that: comprise the photoelectric conversion unit that the light source emitter that is arranged in the special conservator of transformer is connected with light source receiver and with light source receiver, the alarm unit being connected with photoelectric conversion unit; Described light source emitter is arranged on the inwall of the special conservator of transformer and is positioned at the pasta top of conservator, light source receiver is arranged on the special conservator inwall of transformer on light source emitter opposite and is positioned at the pasta below of conservator, light source emitter at an angle by launching site light beam irradiates to the light source receiver of conservator opposite side.
