Description
Technical field
The utility model relates to a kind of vacuum oil warning device.
Background technology
National regulation, 220kV and above transformer, reactor must vacuum oils when installation or overhaul.At present, method of operating commonly used when carrying out vacuum oil has: the one, carry out the judgement of pasta by artificial thoughts and feelings oil tank of transformer wall temperature variation and oil mass estimation, waste time and energy, error is bigger, cause easily because of oil-filled deficiency and expose insulation, have a strong impact on the safety of transformer body insulation, or because of the oil-filled oil spill accident that too much causes; The 2nd, by increasing operating personnel's quantity, monitor that by turns the transparent pipeline of vacuum at casing top is judged, because transformer vacuum oil is generally all at dead of night or carry out morning, so the manpower and materials that expend are bigger, efficient is lower.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy to operate at above-mentioned deficiency, and can improve the vacuum oil warning device of vacuum oil success ratio and work efficiency.
For solving the problems of the technologies described above, the design feature of this vacuum oiling warning device is: comprise the connection pedestal, connect pedestal and be provided with bleeder vent, the below that connects pedestal is connected with support, be connected with the slide bar that slides up and down on the support, the bottom of slide bar is connected with ball float, and the top of slide bar is connected with magnet, on the connection pedestal the dried spring sensor corresponding with magnet is installed, dried spring sensor is electrically connected with acousto-optic element, power supply formation.
This vacuum oiling warning device is to utilize ball float to trigger the principle that acousto-optic element reports to the police when floating to constrain height on the oiling liquid level to carry out work, for the ease of installing, this vacuum oiling warning device comprises that connects a pedestal, this connection pedestal matches with the joint flange of oil tank of transformer, because this vacuum oiling warning device is mounted in the fuel tank and uses, in order to guarantee reliable trigger, this vacuum oiling warning device adopts magnet to trigger dried spring principle of sensors and triggers, during use, the part that will connect below the pedestal by fuel tank top inlet reaches in the fuel tank earlier, to connect pedestal again aligns with fuel tank top inlet flange, contact with dried spring sensor is electrically connected with the acousto-optic element and the power supply formation of fuel tank outside again, then, with bolt with vacuumizing joint, connecting pedestal and fuel tank ring flange is tightened in together, at last, vacuum pump is connected on the vacuumizing joint vacuumizes by bleeder vent, and oiling gets final product in fuel tank, when the oiling liquid level touches ball float, ball float begins with the height of oiling liquid level to rise gradually, because ball float top connects magnet by slide bar, so magnet also raises gradually with the rising of oiling liquid level, magnet rises highly more, the distance of magnet and dried spring sensor is also just near more, when the oiling liquid level arrives specified altitude, magnet also reaches the distance that triggers dried spring sensor, at this moment, two normally opened contact closures of dried spring sensor, the supply access of acousto-optic element is connected, acousto-optic element sends alerting signal, thereby alert stops oiling, has improved the success ratio of vacuum oil greatly, and has reduced by special personnel that check the oiling liquid level, it is more reasonable that personnel are disposed, and work efficiency is higher.
As improvement, in order to make this vacuum oiling warning device convenient in use, the top that connects pedestal is equipped with vacuumizing joint, the connection terminal that passes vacuumizing joint is installed on the vacuumizing joint, be provided with the insulated enclosure pad between connection terminal and the vacuumizing joint, connection terminal is electrically connected with dried spring sensor, acousto-optic element and power supply formation.
After the improvement, can directly this vacuum oiling warning device be installed on the inlet flange dish of fuel tank, just can carry out vacuum oil work after reconnecting vacuum pump, very quick, avoided installing separately again vacuumizing joint and to the trouble of outer lead.
As further improvement, in order to improve the reliability of this vacuum oiling warning device, support is slidingly connected by sliding sleeve and slide bar.
Slide bar and between between be provided with after the sliding sleeve, will be more smooth and easy when slide bar slides up and down, thereby can prevent effectively that ball float from driving in the process that slide bar slides up and down causes the fault of reporting to the police and losing efficacy because of being blocked by support.
As further improving again, in order to prevent magnet dried spring sensor is caused mechanical impact, slide bar is provided with spacing screw, is bolted with caging bolt in the spacing screw.
In sum, adopt the vacuum oil warning device of this structure, simple in structure, easy to operate, and can improve vacuum oil success ratio and work efficiency, and suit when transformer or reactor installation or overhaul, to use, be particularly suitable under the personnel shortage situation, using.
