Description
Technical field
The utility model relates to converting equipment, and particularly high-power transformer vacuum capsule oil conservator is provided with the oil resistant capsule in this oil conservator, and it and transformer main fuel tank, switch tank are simultaneously or vacuumize separately.
Background technology
" preventing the high-power transformer damage accident " 932 and 933 in " 18 great anti-accident measures of electrical network of State Grid Corporation of China " spells out: " transformer after new installation and the overhaul should be in strict accordance with related standards or producer's specified vacuum oiling and Circulation and Hot Oil Spray; vacuum degree, pumpdown time, oil injecting speed and Circulation and Hot Oil Spray time, temperature all should reach requirement.Fuel tank on load tap changer should vacuumize according to identical requirement simultaneously." " high-power transformer of seal capsule or barrier film is housed, must carries out oiling in strict accordance with the technological requirement of manufactory's specification regulation, prevent that air from entering.
At present, the transformer that homemade 110KV level is above, oil resistant capsule (or barrier film) all is equipped with in oil conservator inside, but owing to vacuumize also and carry out on oil tank of transformer, so have many uses, " capsule oil conservator " that advantage is a lot of be subjected to the puzzlement that self can not vacuumize.Because making transformer oil expand, the variation of temperature of oil in transformer shrinks the operate as normal of sending suction of appearance.But oil conservator can not vacuumize at present, and vacuumizing is to carry out on oil tank of transformer.When if oil conservator vacuumizes, the oil resistant capsule is easy to the oil conservator vacuum orifice is blocked or influenced the quality that vacuumizes of oil conservator, also cause the breakage of oil resistant capsule when vacuumizing easily, because vacuumizing of oil conservator is to carry out on oil tank of transformer, operation is very inconvenient, intensity of workers is big again
Summary of the invention
The purpose of this utility model is to propose a kind of transformer vacuum capsule oil conservator technical scheme, this vacuum capsule oil conservator can or vacuumize separately with the oil tank of transformer while, and can vacuumize the oil resistant capsule, all valves are arranged on the position that personnel can touch on ground.
The technical solution of the utility model is to realize like this, a kind of transformer vacuum capsule oil conservator, this oil conservator includes a sealed hollow main cabinet, the both sides of main cabinet are the main cabinet Closed end plate, in cavity, be placed with the oil resistant capsule of sealing, on the end plate of main cabinet one side, be provided with oil level indicator, pay cabinet by being welded to connect a loaded switch oil storage on the end plate of main cabinet opposite side, be provided with oil level indicator cashier's office in a shop paying, on described main cabinet top at least two through holes that connect with cavity are set, on two through holes, are respectively arranged with the gentle stream damper of suction head; Described air-breathing first end is in cavity, and the suction head other end connects a vacuum-pumping tube outside main cabinet, is connected to valve A on vacuum-pumping tube earlier, and valve A back meets valve B again; Described air-flow buffer one end is connected on the oil resistant capsule by pipeline in cavity and is communicated with the capsule inner chamber, and the air-flow buffer other end connects a capsule air intake duct outside main cabinet, be connected to valve C on the capsule air intake duct earlier, and valve C back meets valve D again; A respirator b is connected on the valve D; Connect one and vacuumize shunt valve between valve A and valve B, this vacuumizes pipeline connection between shunt valve while and valve C and the valve D, vacuumizes valve E is housed on the shunt valve; At least two through holes with the cavity perforation are set in described main cabinet bottom, two through holes be connected with respectively oil fuel tube and with oil tank of transformer communicating pipe, be separately installed with valve H and valve I at oil fuel tube with on communicating pipe.
The beneficial effects of the utility model are:
1. in this oil conservator the oil resistant capsule is housed.When the volume of transformer oil changed, oil conservator did not directly suck, air-out, but reconciled the oil level variation of oil conservator by the variation of capsule volume.Transformer oil is not directly contacted with air, prevent that transformer oil is by air pollution, oxidation, rotten.
2. oil conservator is for adapting to the needs vacuumize, and the spy is provided with special-purpose suction head, makes the respirator connecting leg communicate with oil conservator or disconnects by Open valve, comes the pressure of balance capsule and capsule outside, is unlikely to when vacuumizing the oil resistant capsule is damaged; When removing the vacuum of capsule, the capsule exit is provided with the air-flow buffer again, and air-flow can not damage capsule yet.
The vacuum-pumping tube of oil conservator and respirator connecting leg side by side guide to apart from ground that about 1.3 meters link to each other with valve.Than the independent fuel tank vacuum oil of original employing, both simplify the program of vacuum oil again by the method for Oil Tank repairing like this, improved the quality of oiling again, also made things convenient for operation.
