Abstract
The utility model discloses an oil storage tank of a transformer and with a filtering function. The oil storage tank comprises a housing, a corrugated tube, a vent and a gas relay; the oil storage tank also comprises a normally-closed electromagnetic valve, an oil pump, a filter and a controller; an oil tank is provided with the filtering opening; the oil inlet of the oil pump is connected with the filtering opening of the oil tank; the normally-closed electromagnetic valve is arranged on an oil tube which is arranged between the oil pump and the oil tank; the oil chamber of the oil storage tank is provided with the filtering opening; the oil outlet of the oil pump is connected with the filtering opening of the oil chamber of the oil storage tank; the filter is arranged on an oil tube which is arranged between the oil pump and the oil chamber of the oil storage tank; a control signal output end of the controller is connected with a control signal input end of the oil pump and a control signal input end of the normally-closed electromagnetic valve. When the oil storage tank of the transformer and with the filtering function works, the oil pump and the normally-closed electromagnetic valve are controlled by the controller to be started, transformer oil is pumped through the oil pump and returns to the oil storage tank after being filtered through the filter, and only a filtering piece which is arranged in the filter needs to be replaced after the transformer is used for a certain period of time.
Description
Technical field
The utility model relates to a kind of transformer oil storage, relates in particular to a kind of transformer oil storage with filtering function.
Background technology
In power equipment, transformer is the capital equipment of lifting voltage, and oil conservator is the protectiveness device of oil-filled transformer indispensability.When the transformer well cuts acquires a certain degree,, in order to prevent its corrosion to insulating material, fuel tank etc., need to filter or change transformer oil, but present most of transformers self do not filter the device of transformer oil.
The utility model content
The purpose of this utility model provides a kind of transformer oil storage with filtering function with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
a kind of transformer oil storage with filtering function, comprise shell, bellows, pneumostome and Buchholz relay, described bellows is arranged on described enclosure, described pneumostome is arranged on a side of described shell, described Buchholz relay is arranged on the oil pocket and the oil pipe between oil tank of transformer of transformer oil storage, described transformer oil storage also comprises normally closed solenoid valve, oil pump, filter and controller, described oil tank of transformer is provided with and filters mouth, the oil-in of described oil pump is connected with the filtration mouth of described oil tank of transformer, described normally closed solenoid valve is arranged on oil pipe between described oil pump and described oil tank of transformer, the oil pocket of described transformer oil storage is provided with and filters mouth, the oil-out of described oil pump is connected with the filtration mouth of the oil pocket of described transformer oil storage, described filter is arranged on oil pipe between the oil pocket of described oil pump and transformer oil storage, the control signal output of described controller respectively at the control signal input of described oil pump be connected the control signal input of normally closed solenoid valve and connect.
Particularly, described transformer oil storage also comprises corrugated flexible hose, and the first end of described corrugated flexible hose stretches into oil tank of transformer inside, and the second end of described corrugated flexible hose is connected with the filtration mouth of oil tank of transformer.
Particularly, the filter in described filter is detachable filter, and there is hand stop valve at described filter and tubing interface place.
The beneficial effects of the utility model are:
When a kind of transformer oil storage with filtering function of the utility model is worked, opened by controller control oil pump and normally closed solenoid valve, oil pump pumps transformer oil from fuel tank, get back to oil conservator after being filtered again, after transformer uses certain hour, only need to change the filter in filter.
Description of drawings
Fig. 1 is a kind of structural representation with transformer oil storage of filtering function of the utility model, and this schematic diagram comprises that the part of oil conservator shell analyses and observe.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
as shown in Figure 1, a kind of transformer oil storage with filtering function, comprise shell 1, bellows 2, pneumostome 3 and Buchholz relay 4, bellows 2 is arranged on shell 1 inside, pneumostome 3 is arranged on a side of shell 1, Buchholz relay 3 is arranged on the oil pocket and the oil pipe between oil tank of transformer 6 of transformer oil storage, transformer oil storage also comprises normally closed solenoid valve 5, oil pump 9, filter 10 and controller 8, oil tank of transformer 6 is provided with and filters mouth, the oil-in of oil pump 9 is connected with the filtration mouth of oil tank of transformer 6, normally closed solenoid valve 5 is arranged on oil pipe between oil pump 9 and oil tank of transformer 6, the oil pocket of transformer oil storage is provided with and filters mouth, the oil-out of oil pump 9 is connected with the filtration mouth of the oil pocket of transformer oil storage, filter 10 is arranged on oil pipe between the oil pocket of oil pump 9 and transformer oil storage, the control signal input that the control signal output of controller 8 is connected with normally closed solenoid valve respectively at the control signal input of oil pump 9 connects.
Transformer oil storage also comprises corrugated flexible hose, and the first end of corrugated flexible hose stretches into oil tank of transformer 6 inside, and the second end of corrugated flexible hose is connected with the filtration mouth of oil tank of transformer 6.In filter, 10 filter is detachable filter, and filter 10 has hand stop valve with the tubing interface place.
The operation principle of transformer oil storage that the utlity model has filtering function is as follows:
At first the time of filtration is set in controller 8, when reaching the filtration time that sets in advance, controller 8 is controlled and is opened normally closed solenoid valve 5 and oil pump 9, oil pump 9 pumps the transformer oil in oil tank of transformer 6, transformer oil after filter 10 filters, returns transformer oil storage, after certain hour, close normally closed solenoid valve 5 and oil pump 9 by controller 8 again, filtration is completed.At set intervals, by the staff, the hand stop valve at filter 10 two ends cuts out, then the filter in filter 10 is taken out and changes, just can work on.
