Abstract: PURPOSE:To form the device capable of filtering and concentrating a material hard to filter by exerting a pressing force and a suction force respectively on one and other sides of a partition wall which is clogged and forms a closed cylinder by the positive and negative pressures produced by a piston moving in the partition wall. CONSTITUTION:When a solid remaining in the partition wall is concentrated, valves 8 and 12 are closed, and a piston 6 is moved toward a lid 1. The volume in the partition wall in the advancing direction of the piston is reduced to form a high-pressure part, and a low-pressure part is formed behind the piston. The raw liq. in the advancing direction of the piston is pressed from inside a filter medium, the liq. is simultaneously sucked by the low-pressure part from the gap 5 side, and the pressing and sucking effects are simultaneously exerted from the front and rear of the filter medium. The filtrate is introduced into the partition wall from the gap 5 behind the traveling piston and passed through a through-hole 4 or the through-hole 4 and filter medium in the opposite direction, and hence the clogged part is successively cleaned off.

Filed: 1984-04-05
Abstract: PURPOSE:To diagnose life expectation of oil-immersed electric apparatus without suspending the operation by loading a test piece of insulation material same as the determined insulation material into an oil tank and detecting failure of test piece from the outside if such test piece shows abnormal condition. CONSTITUTION:An oil tank 18 is provided at the internal upper part of reservoir 12 and a test apparatus 20 providing an insulation material test piece 20a immersed in the insulation oil 18a is housed at the inside of such oil tank 18. The insulation oil 18a of oil tank 18 can be adjusted a temperature almost equal to the maximum winding temperature of winding 11 of the transformer body 11. A test piece 20a is made of the insulation material which is also used for insulation material of the body 11. With such structure, a test piece 20a at the inside of oil tank 18 shows the aging deterioration which is equal to that of insulation material which reaches the maximum temperature of winding. Therefore, when the test piece 20a at the inside of oil tank 18 is mechanically destroyed, it can be estimated that the mechanical strength of insulation member of the part which reaches the maximum temperature of transformer 17 is lowered up to 60% of initial strength. Highly accurate diagnosis can be realized by judging deterioration degree from mechanical strength as described above.
