The online oil filter device of the load tap changer comprises a chassis, an impurity filter, a dewatering filter, an oil pump, a drive motor and a controller, wherein the impurity filter, the dewatering filter and the oil pump are sequentially connected according to a flow direction of switch oil. A pipeline on the chassis is provided with an oil inlet and an oil outlet. The drive motor is in mechanical connection with the oil pump. The pipeline is further provided with an electronic flowmeter, and the electronic flowmeter and the drive motor are in electrical connection with the controller. The controller can display real time data of the flowmeter and possesses a low rotating speed warning function. The online oil filter device of the load tap changer can timely detect whether the impurity filter is replaced or not, so that operation stability of the load tap changer is guaranteed.
Description
Technical field
The utility model relates to the oil filtering unit field, especially, is a kind of on-line oil filter device of on-load tap-changer.
Background technology
The on-load tap-changer on-line oil filtering machine is to switch in the grease chamber in order to solve on-load voltage regulating switch, because arcing, insulating oil very easily decomposes, wears out and produces a large amount of free carbons and metal fragment etc., causes insulating oil breakdown voltage to reduce, the product of dielectric property variation the problems referred to above research and development.It is mainly used in the filtration of transformer on-load tap changer insulating oil.Equipment can be in the situation of the normal operation of transformer, switch instances automatic on-line oil strain according to tap changer, effectively remove free carbon, moisture, cracking impurity and acid in the oil, recover dielectric strength and the performance of tap switch oil, improve on load tap changer Operation safety, reliability, greatly reduce the transformer frequency of power cut, improve power supply reliability.
Tradition online oil filtration machine is by the impurity cleaner, dehydration filter, oil pump and controller form, wherein the impurity cleaner must be changed in use for some time, and this time generally can be how long to use, yet in the practice process, because every on load tap changer has different separately operating modes, larger such as the loaded tap-off wearing and tearing that have, therefore the larger heating of electric arc that causes is more, it is faster that corresponding oil just worsens, it is different that the difference of this individuality causes the actual life of impurity cleaner just, enter saturation condition if the impurity cleaner is too early, can cause filter screen to break in the time of serious, and then affect the stability of on load tap changer.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of on-line oil filter device of on-load tap-changer, and whether this loaded tap-off oil-filtering apparatus can accurately detect the impurity cleaner and should change.
The technical scheme that its technical problem that solves the utility model adopts is:
This on-line oil filter device of on-load tap-changer comprises cabinet, contaminant filter, except water filter, oil pump, drive motors and controller, described contaminant filter, removing water filter and oil pump is linked in sequence by the circuit-breaker oil flow direction by pipeline, described pipeline is provided with oil-in and oil-out at described cabinet, described drive motors links to each other with described oil pump machinery, also be provided with electronic flowmeter on the described pipeline, described electronic flowmeter and drive motors and described controller are electrically connected, and described controller is crossed the controller of low warning function for showing flowmeter real time data and tool rotating speed.
As preferably, described electronic flowmeter is arranged on contaminant filter and except between the water filter.
As preferably, described electronic flowmeter front is transparent toughened glass, and reverse side inside is provided with backlight.
The utility model has the advantage of:
Come the flow of Real-Time Monitoring contaminant filter with electronic flowmeter, utilize simultaneously the more impurity of contaminant filter self-filtering can cause the lower characteristics of flow, when the contaminant filter flow is lower than warning value, even carry out the replacing of cleaner according to the warning of controller, guaranteed the stability of on load tap changer operation.
Description of drawings

Among the figure: 1, cabinet; 11, oil-out; 12, oil-in; 2, controller; 3, oil pump; 31, drive motors; 4, except water filter; 5, contaminant filter; 6, electronic flowmeter; 61, transparent toughened glass; 62, backlight.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Figure 1 shows that the planform schematic diagram of an embodiment of this on-line oil filter device of on-load tap-changer, Fig. 2 is that structural representation is dissectd in the inside of Fig. 1 embodiment electronic flowmeter, problem is now set forth as same embodiment Fig. 1, Fig. 2 to the utility model for convenience of explanation.
In the present embodiment, this on-line oil filter device of on-load tap-changer comprises cabinet 1, contaminant filter 5, except water filter 4, oil pump 3, drive motors 31 and controller 2, described contaminant filter 5, removing water filter 4 and oil pump 3 is linked in sequence by the circuit-breaker oil flow direction by pipeline, described pipeline is provided with oil-in 12 and oil-out 11 at described cabinet 1, described drive motors 31 links to each other with described oil pump 3 machineries, also be provided with electronic flowmeter 6 on the described pipeline, described electronic flowmeter 6 and drive motors 31 are electrically connected with described controller 2, and described controller 2 is crossed the controller of low warning function for showing flowmeter real time data and tool rotating speed.
Above-mentioned on-line oil filter device of on-load tap-changer, described electronic flowmeter 6 is arranged on contaminant filter 5 and removes between the water filter 4, because impurity is far longer than moisture to the impact except water filter 4 to the impact of contaminant filter 5, so because monitor accurately contaminant filter 5 as far as possible.
Above-mentioned on-line oil filter device of on-load tap-changer, described electronic flowmeter 6 fronts are transparent toughened glass 61, reverse side inside is provided with backlight 62, after controller 2 sends the excessively low warning of flow, observe oily color from transparent toughened glass 61 and judge degree of oxidation, thereby whether determine switch oil should be changed.
Above-mentioned on-line oil filter device of on-load tap-changer operation principle:
Come the flow of Real-Time Monitoring contaminant filter 5 with electronic flowmeter 6, utilize simultaneously the more impurity of contaminant filter 5 self-filterings can cause the lower characteristics of flow, when contaminant filter 5 flows are lower than warning value, even carry out the replacing of cleaner according to the warning of controller 2, guaranteed the stability of on load tap changer operation.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
