Background technology
In the prior art, instrument transformer is the chief component of power transmission and transforming equipment, and its effect (1) is to make secondary device and high voltage isolation such as measuring instrument, relay, to guarantee the safety of the person and equipment.(2) be when circuit is short-circuited, the protection measuring instrument makes it not be subjected to the damage of big electric current.At present, instrument transformer in use still following problem can occur:
1, need regularly take every year oil sample to carry out oiling and test analysis;
2, there is the defective of seepage oil in instrument transformer self;
3, influenced by ambient temperature, expand with heat and contract with cold.
Above reason causes the oil immersed type instrument transformer when operation, the defective of low on fuel often occurs.We know that for hermetically sealed product, low on fuel can make the metal expander at instrument transformer top can not be in normal operating state, cause instrument transformer inside negative pressure to occur, thereby cause product to make moist, and the disastrous effect of scaling loss or blast appears in decreasing insulating.Therefore, when oil level descends, should in time increase qualified transformer oil, guaranteeing the normal operating conditions of instrument transformer, thereby with accident treatment in bud.
For a long time, continue to use the working method of power failure repairing, operation item is various always, misoperation takes place easily or leak an operation, and is beyond measure especially by the loss that power failure causes.Because operational environment is work high above the ground, and is not only dangerous higher, and labour intensity is big, inefficiency.
Summary of the invention
To be solved in the utility model is exactly must have a power failure during the instrument transformer repairing in the prior art, and the operation project is various, and work high above the ground danger is higher, labour intensity is big, problems such as inefficiency, and a kind of structure uniqueness, the novelty that provide are simple to operate, easy to carry, do not need additional supply during operation, also need not have a power failure gets final product charged repairing, and repairing speed is fast, time saving and energy saving, high efficiency and do not need work high above the ground, the safe and reliable manual charged oil compensator of oil immersed type instrument transformer.
Technical solution of the present utility model is to realize like this.The manual charged oil compensator of oil immersed type instrument transformer, comprise oil pump, relief valve, flowline, special-purpose fuel feeding valve, instrument transformer fuel outlet valve, oil immersed type instrument transformer, oil inlet pipe and fuel tank, one end of oil inlet pipe inserts in the fuel tank, the other end is connected with oil pump, the exit of oil pump is provided with threeway, relief valve is equipped with in a termination of threeway, another termination is connected with an end of flowline by the oil pump outlet connection, the other end of flowline links to each other with special-purpose fuel feeding valve, and special-purpose fuel feeding valve is connected with the oil immersed type instrument transformer by the instrument transformer fuel outlet valve.
Described special-purpose fuel feeding valve is made up of adjusting rod, gland, packing, filter screen, vent valve, flange, cover stave, oil drain out, unidirectional valve and fuel feeding valve body, vent valve is equipped with in the top of fuel feeding valve body, the below of fuel feeding valve body is equipped with oil drain out and unidirectional valve respectively, the import of unidirectional valve is connected with flowline, filter screen is located in the fuel feeding valve body, one side of fuel feeding valve body is equipped with packing, packing is connected with gland, the opposite side of fuel feeding valve body is equipped with flange, and adjusting rod passes gland, packing, filter screen, flange and is connected with the cover stave.
The characteristics of the utility model maximum are to have realized online charged repairing, have removed various operation item from, and the danger of misoperation can not take place, and it is very convenient to operate, and controls the repairing amount easily, have avoided the loss of outage that causes because of repairing, and labour intensity is little, and is time saving and energy saving.Because this device does not need work high above the ground, safe and reliable, operational environment is greatly improved, and operating efficiency significantly improves, and is specially adapted to the repairing operation of the instrument transformer of various models.
