Description
Technical field
The utility model belongs to the service equipment of high-tension power transmission and transformation equipment, relates to a kind of vacuum oil machine that outdoor high-voltage current transformer or voltage transformer are carried out repairing of being used for.
Background technology
In the use of high-tension current inductor or voltage transformer, along with increase and changes of seasons service time, the oil level of the insulation oil product in it has decline, needs regularly to its repairing out of doors.For this a spot of repairing, if adopt of the pouring orifice oiling of existing common oiling equipment, be easy to generate bubble from current transformer or voltage transformer bottom, when entering, bubble easily causes insulation fault between the mutual inductor coil; And if carry out repairing from the open top of outdoor high-voltage instrument transformer, often need to have a power failure, must remove top cover during operation, trouble very, and because operation aloft, no secure support has certain risk.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of vacuum oil machine is provided, and makes it carry out repairing to it from the bottom pouring orifice of outdoor high-voltage instrument transformer, and the repairing process is safe and reliable, can not produce bubble, and need not to have a power failure.
Vacuum oil machine of the present utility model includes an oil storage tank, the import of oil storage tank is communicated with total oil-in through an electromagnetically operated valve and filter that is serially connected in the pipeline, oil storage tank top is connected with a vacuum pump by pipeline, the oil storage tank bottom has two pipelines to be connected with oil fuel tube, wherein be serially connected with an electromagnetically operated valve and an oil pump in a pipeline, be connected with an electromagnetically operated valve in another pipeline, the rear end of oil fuel tube is total oil-out, before total oil-out a vacuum valve is arranged.Import department at above-mentioned oil storage tank also can be equipped with a float valve, with automatic control liquid level.Between the import of above-mentioned filter outlet and oil pump, also be connected with an electromagnetically operated valve, this equipment can be used as a simple oil filter.
The utility model can carry out repairing by the bottom pouring orifice from high-voltage mutual inductor under the condition that does not have a power failure, simple to operate, safety, and its pipeline structure is reasonable, and whole oiling process is carried out under vacuum state, has stopped the product dirt of bubble.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, total oil-in 2 of this vacuum oil machine is communicated with the import of oil storage tank 1 through a filter 3 and an electromagnetically operated valve 4, in oil storage tank import department a float valve 13 is installed also, with oil level in the automatic control jar.Oil storage tank 1 top is connected with a vacuum pump 5 by pipeline, also can be connected an electromagnetically operated valve 12 between vacuum pump and the oil storage tank, is sucked by vacuum pump when preventing that jar interior oil-feed or oil level are too high and influences useful life of pump.Oil storage tank 1 bottom has two pipelines to be connected with oil fuel tube 9, wherein is serially connected with electromagnetically operated valve 6 and 7 oil pumps in a pipeline, is connected with electromagnetically operated valve 8 in another pipeline, and the rear end of oil fuel tube 9 is total oil-out 10, before total oil-out a vacuum valve 11 is arranged.
In the process of reality to the repairing of outdoor high-voltage instrument transformer, total oil-out 10 is connected with on the pouring orifice of outdoor high-voltage instrument transformer bottom.Before the oil-feed of vacuum oil machine equipment, at first electromagnetically operated valve 4 and vacuum valve 11 are closed, electromagnetically operated valve 8 and electromagnetically operated valve 12 are opened, starting 5 pairs of whole oil circuits of vacuum pump vacuumizes, close electromagnetically operated valve 8, electromagnetically operated valve 6 and electromagnetically operated valve 12 then, open electromagnetically operated valve 4, make the oil storage tank oil-feed, by stopping oil-feed behind the certain oil level of float valve control arrival, close electromagnetically operated valve 4 and oil product is vacuumized processing this moment; Before the high-voltage mutual inductor oiling, open vacuum valve 11 earlier, owing to be vacuum state in the oiling pipeline, the oil product in the high-voltage mutual inductor promptly refluxes and is full of pipeline, this moment is opens solenoid valve 6 again, and starts oil pump 7, and instrument transformer is carried out repairing.Because the said process oil product is in vacuum state, thereby can not produce bubble.
In addition, also be connected with an electromagnetically operated valve 14 between the import of above-mentioned filter 3 outlets and oil pump 7, opens solenoid valve 14 is closed electromagnetically operated valve 4 and electromagnetically operated valve 6, and oil product is circulated without oil storage tank, and equipment is used as a simple oil filter.
