The oil tank is connected with the vacuum drying chamber through an oil suction pipe, a content gauge, an electrical heated tube and a thermometer are arranged in the oil tank, an oil suction valve is arranged oil suction pipe, and an air evacuation valve is arranged on the vacuum drying chamber. The vacuum pump is connected with the filter through the air suction pipe, an air evacuation pipe and oil injection hole are arranged on the vacuum pump, and the oil suction valve is arranged on the air suction pipe. The automatic oil immersing device removes potential safety hazards of hot oil scalding, is smooth in test procedure flow, and improves work efficiency and accuracy of testing results.
Description
Technical field:
The utility model relates to a kind of automatic device for soaking oil that is used for the preceding sample of eleatrical insulating board electrical strength oil test.
Background technology:
The test of eleatrical insulating board electrical strength is tested in the empty G&O of 23 ℃ ± 3k according to the requirement of IEC60243-1.Be used for the sample that oil is tested, specimen size 300mmx300mm, each is opened to separate with onesize copper mesh and is placed on one and adorns in the cone; Put basin in the vacuum drying chamber into, temperature be 105 ℃ ± 5k, pressure less than the condition of 100pa under dry 24 hours, open vacuum drying chamber then and take out the dress cone; Then will be preheating to 80 ℃ ± 10k, meet the oil that IEC60296Class|| requires, join in the basin with enough slow speed; Make sample immerse in the oil fully; Put into vacuum drying chamber to basin again, make sample under the atmospheric conditions of 80 ℃ ± 10k, in oil, be no less than 24 hours; Then sample is cooled off under the temperature of 23 ℃ ± 5k; This moment, sample will immerse in the oil fully, put into sample between the electrode that is immersed in oil groove then and tested, and there are two defectives in existing this sample immersion oil process: the one, and testing standard requires sample can not be exposed to the air from vacuumizing the overall process that is dried to the test completion; Be exposed in the air when sample is taken out immersion oil after dry 24 hours in vacuum drying chamber now, can be influential to the test result accuracy; The 2nd, the manual scald accident that takes place easily that adds when being heated to 80 ℃ ± 10k to oil.
Summary of the invention:
The utility model purpose is: provide a kind of test result accurately and the automatic device for soaking oil that is used for sample before the test of eleatrical insulating board electrical strength oil of high efficiency.
The technical scheme of the utility model is: it comprises vacuum pump, filtrator, fuel tank, vacuum drying chamber, dress cone, and fuel tank links to each other through fuel sucking pipe with vacuum drying chamber, is provided with liquid level gauge, electrothermal tube, thermometer in the fuel tank; Fuel sucking pipe is provided with oil sucting valve, and vacuum drying chamber is provided with vent valve; Vacuum pump links to each other through air intake duct with filtrator, and vacuum pump is provided with gas outlet, oil hole, and air intake duct is provided with inlet valve.
The advantage of the utility model: 1, make in the eleatrical insulating board electrical strength oil before the test that sample can not be exposed in the air in the sample immersion oil process, satisfy the requirement of IEC60243-1 standard fully, improved precision of test result; 2, eliminated the hidden danger that deep fat is scalded; 3, the test process flow process is smooth and easy, has improved work efficiency.
Description of drawings:
Fig. 1 is the utility model structural representation
Embodiment:
As shown in Figure 1, it comprises vacuum pump 1, filtrator 2, fuel tank 5, vacuum drying chamber 7, dress cone 8, and fuel tank 5 links to each other through fuel sucking pipe 13 with vacuum drying chamber 7, is provided with liquid level gauge 3, electrothermal tube 4, thermometer 6 in the fuel tank 5; Fuel sucking pipe 13 is provided with oil sucting valve 14, and vacuum drying chamber 7 is provided with vent valve 15; Vacuum pump 1 links to each other through air intake duct 12 with filtrator 2, and vacuum pump 1 is provided with gas outlet 9, oil hole 10, and air intake duct 12 is provided with inlet valve 11.
During use; Each is opened to separate to be placed on onesize copper mesh and adorns in the cone 8 sample; To adorn cone 8 and put into vacuum drying chamber 7; Closed the door of vacuum drying chamber 7, regulated baking temperature at 105 ℃ ± 5k of standard-required, open vacuum pump 1 vacuumize standard-required pressure less than the condition of 100pa under dry 24 hours.The electrothermal tube of opening in the fuel tank 54 is heated to 80 ℃ ± 10k of standard-required to oil; Slowly open fuel tank 5 then and lead to the oil sucting valve 14 on the oil pipe of vacuum drying chamber 7, oil slowly flows into 8 li of dress cones in the vacuum drying chamber 7, lets sample all be immersed in the oil; Stop vacuum pump 1; The temperature of regulating vacuum drying chamber 7 is at 80 ℃ ± 10k of standard-required, lets the sample be under the atmospheric pressure of 80 ℃ ± 10k in temperature, is immersed in to be no less than 24 hours in the oil; Be to cool off under 23 ℃ ± 5 the temperature in temperature with sample then, the sample that immerse fully in the oil this moment can get into next step test.
