Description
Technical field
The present invention relates to electric power chemistry environmental technology fields, particularly relate to a kind of loaded switch on-line intelligence oil filter.
Background technique
In recent years, the requirement of power grid and power consumer to quality of voltage is higher and higher, accesses the change of idle work optimization system
The action frequency of depressor load ratio bridging switch increased significantly, and this frequent movement accelerates the deterioration of insulating oil, according to there is load
Switch maintenance directive/guide, it is every switching 5000~10000 times or 1~2 year or oil in breakdown voltage be lower than 25KV when, need to have a power failure
Cleaning of uncapping is changed oil or oil strain is primary, and Repair of Transformer period longest can extend to 6 years after being overhauled according to virtual condition, but
The oil of loaded switch insulating oil be difficult to remain to it is consistent with the transformer body time between overhauls(TBO), cause transformer involvement have a power failure, shadow
Ring the reliability index of transformation facility.
Summary of the invention
The invention discloses a kind of loaded switch on-line intelligence oil filters, and on-line real time monitoring oil, effectively purification are oily,
Reduce transformer frequency of power cut, improves the availability of transformer equipment.
The present invention is achieved by the following technical solutions:
A kind of loaded switch on-line intelligence oil filter, including filter, water suction filter core, accurate filter, have load in operation
The fuel tank both ends of switch are respectively equipped with oil inlet and oil outlet, and the oil inlet is sequentially connected filter by pipeline, water suction is filtered
Core, accurate filter, finally connect oil outlet, and the oil inlet is to being sequentially connected moisture detector and oil inlet electricity between filter
Magnet valve, the filter are sequentially connected oil drain pump, pressure controller and pressure gauge between water suction filter core, and the water suction filter core is extremely
It is sequentially connected check valve and pressure gauge between accurate filter, the accurate filter is to being sequentially connected sampling valve between oil outlet
With oil outlet solenoid valve.
Preferably, the moisture detector, oil inlet solenoid valve, filter, oil drain pump, pressure controller, pressure gauge, water suction
Filter core, check valve, accurate filter, sampling valve, oil outlet solenoid valve are connected with PLC control cabinet.
Preferably, the PLC control cabinet is equipped with the very color touch screen of Siemens.
Preferably, the connected pipes of the oil inlet and oil outlet use the screw-type fast interface of DILO company of Germany.
Compared with prior art, the beneficial effects of the present invention are:
The online oil treatment provisions of on-load voltage regulating switch of the invention are to adsorb moisture content in traditional equipment filter element filtering impurity
On the basis of increased online insulating oil voltage resistant monitoring newly, the data of loaded switch operating mechanism Stateful Inspection, backstage monitoring of software are adopted
The functions such as collection, analysis realize purification oil, monitor on-line and avoid carrying light gas frequent movement, to reduce change
Depressor frequency of power cut improves the availability of transformer equipment.

Specific embodiment
The following further describes the present invention with reference to the drawings:
A kind of loaded switch on-line intelligence oil filter, including filter 4, water suction filter core 8, accurate filter 10, are running
The fuel tank both ends of loaded switch are respectively equipped with oil inlet 1 and oil outlet 13, and the oil inlet 1 is sequentially connected filter by pipeline
4, absorb water filter core 8, accurate filter 10, final to connect oil outlet 13, and the oil inlet 1 is sequentially connected water between filter 4
Part detector 2 and oil inlet solenoid valve 3, the filter 4 are sequentially connected oil drain pump 5, pressure controller 6 between water suction filter core 8
With pressure gauge 7, the water suction filter core 8 is to being sequentially connected check valve 9 and pressure gauge 7 between accurate filter 10, the precision mistake
Filter 10 is to being sequentially connected sampling valve 11 and oil outlet solenoid valve 12 between oil outlet 13.
The moisture detector 2, oil inlet solenoid valve 3, filter 4, oil drain pump 5, pressure controller 6, pressure gauge 7, water suction
Filter core 8, check valve 9, accurate filter 10, sampling valve 11, oil outlet solenoid valve 12 are connected with PLC control cabinet.
The PLC control cabinet is equipped with the very color touch screen of Siemens.
The connected pipes of the oil inlet 1 and oil outlet 13 use the screw-type fast interface of DILO company of Germany.
Working principle: the present invention is connected on the fuel tank of the loaded switch of operation, when moisture content monitor 2 monitors in oil pipe
Oil it is exceeded when, automatic starting present invention operation is filtered processing, is first turned on oil inlet solenoid valve 3, oil circuit successively passes through
Filter 4, water suction filter core 8 and accurate filter 10, are filtered operation to oil circuit, absorb oil by macromolecule water uptake filter core 8
