Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1 is housing, 2 is the damaged instrument of capsule, and 3 be pressure sensor, and 4 be pressure digital display instrument, and 5 is oil level indicator, and 6 is capsule, and 7 is vacuum-pumping pipeline, and 8 is dehydrating breather pipeline, and 9 is the pipeline that is connected with transformer, and 10 note pipeline of draining the oil for oil conservator, and 11 is feculence box.
Embodiment
Below in conjunction with Figure of description, the present invention is further elaborated.
As shown in Figure 1, a kind of oil conservator with multiple monitoring mode of the present invention, it is characterized in that: there is housing 1, vacuum-pumping pipeline 7, dehydrating breather pipeline 8, oil conservator note drain the oil pipeline 10, feculence box 11 and the pipeline 9 that is connected with transformer, its middle shell 1 is provided with vacuum-pumping pipeline 7, dehydrating breather pipeline 8, oil conservator note drain the oil the interface of pipeline 10, feculence box 11 and the pipeline 9 that is connected with transformer, housing 1 inside is provided with capsule 6, and it is connected with dehydrating breather pipeline 8; Housing 1 is also provided with the damaged instrument 2 of capsule and oil level indicator.
Described oil level counts pressure type oil level indicator, and have pressure sensor 3 and pressure digital display instrument 4, wherein pressure sensor stretches in oil conservator by lower housing portion, and holding wire is connected with pressure digital display instrument 4, and signal is delivered to control room.
Oil level indicator also can be float-ball type oil level indicator 5, and ball float floats in housing 1, and the oil level monitor be connected with ball float is installed on outside housing 1.
Therefore the oil conservator that the present invention possesses multiple monitoring mode can realize the oil level monitoring of two kinds of principles, a kind of pressure principle, a kind of ball float principle.
Pressure principle oil level indicator is made up of two parts, and a part is pressure sensor 3, and another part is pressure digital display instrument 4.Pressure sensor is installed on lower housing portion, by level height in piezo-resistance monitoring housing, Signal transmissions on pressure digital display instrument 4, realizes oil level monitoring and high and low warning, and can send control room analog signal.Because oil conservator is when carrying out vacuumizing process, easily damage instrument, therefore the present invention is at the oil-in place mounted valve of pressure sensor, and need this valve to turn off before oil conservator vacuumizes, limit sample just can protect pressure sensor to damage.
