According to the device for monitoring the oil quality of the on-load tap-changer oil cavity, even number of monitoring supporting points on the same section are uniformly distributed on the inner wall of the oil cavity; a laser emitting device and a photosensitive sensor are respectively arranged through each two monitoring supporting points with opposite oil cavity circular centers; the laser emitting device is electrically connected with a switch power supply; the photosensitive sensor is electrically connected with a monitoring module which is used for converting a simulated electric signal into a digital signal; the monitoring module is provided with a display for displaying digital signal information; and the device can accurately monitor the quality of the oil of the on-load tap-changer oil cavity in time, so that the quality of the oil is improved by adopting corresponding measures.
Description
Technical field
The present invention relates to the potential device field, especially, is a kind of loaded tap switch oil chamber oil monitoring device.
Background technology
The indoor transformer oil that is full of of loaded tap switch oil, this is because transformer oil has the dielectric strength more much higher than air.Insulating material is immersed in the oil, not only can improve dielectric strength, but also can avoid the erosion of moisture; The specific heat of transformer oil is big, the cooling medium of doing commonly used.The heat that produces during the transformer operation rises the oily expanded by heating near iron core and winding, and through the convection current up and down of oil, heat sheds through heating radiator, guarantees that transformer normally moves; On the on-load voltage regulating switch of oil-break and transformer, contact can produce electric arc when switching.Because the transformer oil good heat conductivity, and under the high temperature action of electric arc, can divide and touch a large amount of gases, produce big pressure, thereby improved the arc extinction performance of medium, electric arc is extinguished very soon.
When load ratio bridging switch switches at on-load fast, insulating oil will decompose generation uncombined carbon, hydrogen and flammable hydrocarbon gas under the effect of electric arc, also will produce the trace meter particle.Impurity such as wherein a part of uncombined carbon and metal particle attach and amass on shunting switch insulating part surface, and near the charged contact that electric field is concentrated, a part is suspended in the oil especially, and the remaining part deposition is at the bottom of switching grease chamber's case.The granule foreign that is distributed in the insulating part surface will reduce the dielectric strength of insulating part; The granule foreign that is suspended in the oil then influences oily voltage breakdown; The quality of the oil during in time the monitoring load ratio bridging switch switches helps the supply voltage quality and realizes uninterrupted power supply.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of loaded tap switch oil chamber oil monitoring device, this device can accurately be monitored the quality of the oil of loaded tap switch oil chamber timely, thereby takes corresponding measure to improve the quality of oil.
The technical solution adopted for the present invention to solve the technical problems is:
Be evenly equipped with the even number monitoring fulcrum that is in same cross section on grease chamber's inwall of this loaded tap switch oil chamber oil monitoring device; Through being respectively arranged with laser beam emitting device and light-inductive device on per two the said monitoring fulcrums respect to one another of the center of circle, grease chamber; Said laser beam emitting device is connected with Switching Power Supply is electric; The monitoring modular that said light-inductive device and changes into digital signal with analog electrical signal is electrically connected, and said monitoring modular is provided with the display of display digit signal message.
As preferably, said monitoring fulcrum is provided with ten.
As preferably, said laser beam emitting device that is oppositely arranged and light-inductive device are arranged on the same monitoring fulcrum, and the said monitoring fulcrum of former said light-inductive device setting is provided with reflectance coating.
As preferably, said monitoring modular is provided with signal output interface, can be connected with the on-load shunting switch oil filter on the said interface, oil filter can be made according to the real-time quality of oil relevantly judge.
The invention has the advantages that:
Simple in structure, can monitor the quality of the indoor oil of loaded tap switch oil in real time, make load ratio bridging switch reduce the possibility that breaks down.
