The utility model relates to the manual charged oil compensator of high-voltage oil circuit breaker that a kind of power transmission and transforming equipment uses.
(2) background technology
In the prior art, high-voltage oil circuit breaker is the chief component of power transmission and transforming equipment, and its effect is the safe operation of disconnection or switch on and protection major network.But, also following problem can appear in use:
1, need regularly take every year oil sample to carry out oiling and test analysis;
2, there is the defective of spray, leakage of oil in oil circuit breaker self;
3, oil level is nonstandard after the overhaul;
4, to cause oil circuit breaker oil level often to occur low or can't see the phenomenon of oil level in the influence of factor such as affected by environment, rising-heat contracting-cold.
We know that capacitor oil role in oil circuit breaker is insulation, arc extinguishing and cooling, when oil level drops to a certain degree, during the circuit breaker breaking operation, the high temperature that electric arc produces has little time cooling through oil reservoir, heat can not in time distribute, just may set off an explosion at cushion space and air-blending, cause serious consequence.So, when the oil circuit breaker oil level is lower than normal oil level when following, must give repairing in time, in right amount, thus with settlement of accident in bud.For a long time, continue to use the mode of operation of power failure repairing, this must carry out such cover program always: monthly plan of work → application power failure → scheduling written instructions → operation → repairing → restoring running send.Operation item is various, maloperation takes place easily or leak an operation, and the energy loss that is caused by power failure is beyond measure especially.Because working environment is aloft work, and is not only dangerous higher, and labour intensity is big, inefficiency.
(3) summary of the invention
To be solved in the utility modelly must have a power failure when being exactly the repairing of prior art mesohigh oil circuit breaker, the operation project is various, aloft work danger is higher, labour intensity is big, inefficiency, problems such as power off time is long, and a kind of structure uniqueness, the novelty that provide, simple to operate, easy to carry, do not need additional supply during operation, need not have a power failure yet and get final product charged repairing, repairing speed is fast, and is time saving and energy saving, high efficiency and do not need aloft work, the safe and reliable manual charged oil compensator of high-voltage oil circuit breaker.
Technical solution of the present utility model is to realize like this.The manual charged oil compensator of high-voltage oil circuit breaker, comprise oil pump, oil outlet pipe, high-voltage oil circuit breaker, oil inlet, fuel tank etc., one end of oil inlet inserts in the fuel tank, the other end is connected with oil pump, the exit of oil pump is provided with threeway, and blowdown valve is equipped with in a termination of threeway, and another termination is connected with an end of oil outlet pipe by the oil pump outlet connector, the other end of oil outlet pipe links to each other with special-purpose oil nipple, and special-purpose oil nipple is connected with high-voltage oil circuit breaker by the circuit breaker oil cock.
Described special-purpose oil nipple is by blow off valve, spring, steel ball, oil outlet pipe connects outside thread, sealing surface, punching jackscrew and oil nipple body are formed, one end of oil nipple body is provided with the outside thread that links to each other with high-voltage oil circuit breaker, the other end is provided with outside thread and the spherical sealing surface that links to each other with oil outlet pipe, in the oil nipple body spring is housed, steel ball, the punching jackscrew, one end of spring is pressed in steel ball on the sealing surface, the other end of spring is equipped with the punching jackscrew, punching jackscrew and oil nipple body are by being threaded, blow off valve is contained in a side of special-purpose oil nipple body, and is connected with the oil nipple body.
The characteristics of the utility model maximum are to have realized on-bne repair, have removed various operation item from, and the danger of maloperation can not take place, and it is very convenient to operate, and 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 aloft work, safe and reliable, working environment is greatly improved, and work efficiency significantly improves, and is specially adapted to the repairing operation of the high-voltage oil circuit breaker of various models.
