Abstract
The utility model relates to a check type SF6 (Sulfur Hexafluoride) inflating device with a non-return function. The check type SF6 inflating device comprises a line breaker and an SF6 steel cylinder. The check type SF6 inflating device is characterized by further comprising a connecting hose and an SF6 pressure gauge, wherein the connecting hose is of a segmental structure, one segment of the connecting hose is a first hose which is used for connecting the SF6 steel cylinder with the SF6 pressure gauge, and the other segment of the connecting hose is a second hose which is used for connecting the SF6 pressure gauge with the line breaker. According to the check type SF6 inflating device with the non-return function, the design is reasonable, the structure is simple, the safety and accuracy of SF6 inflating can be improved to the maximum, and the service range is wide, so that the check type SF6 inflating device has good economic benefits.
Description
Technical field
The utility model relates to a kind of return-stopping function verification formula SF6 inflator that has.
Background technique
SF6 is as insulation and the arc-extinguishing medium of circuit breaker, GIS equipment, in case pressure decreased defective and SF6 Leakage Gas occur, then be urgent defective or be significant deficiency that intractability is large, and the time is long, directly has influence on the normal operating condition of switching device.The SF6 inflator that uses at present mainly includes the SF6 gas cylinder, reduction valve, and the inflated rubber pipeline, the gas-charging connection of various circuit breakers connects and composes successively.The present normal inflator that uses, in use, owing to the generation that can occur phenomenons such as ftractureing, aging after the long-time use of rubber pipe; And the inflatable interface of circuit breaker all must be changed with the each inflation of being connected of rubber pipe, length consuming time, and sealing is poor; In gas replenishment process, the check formula SF6 density monitor Chang Zuowei reading foundation of breaker apparatus self, but present SF6 circuit breaker mostly is outdoor operation, long-play, exist the souvenir validity poor, descend easily, and can't check before the inflation maintenance, will there be the too high or too low risk of gas pressure in the tonifying Qi process, either way might causes breaker apparatus generation serious consequence in service; Employed SF6 circuit breaker gas-charging connection is different, must be equipped with various interface when test, and not have interchangeability.
The model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of can overcome defects have a return-stopping function verification formula SF6 inflator, make things convenient for circuit breaker to replenish SF6 gas, guarantee the tonifying Qi effect.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of have a return-stopping function verification formula SF6 inflator, comprise circuit breaker and SF6 steel cylinder, it is characterized in that, also comprise connecting hose and SF6 pressure gauge, connecting hose is segmental structure, one section is that the first flexible pipe connects SF6 steel cylinder and SF6 pressure gauge, and another section is that the second flexible pipe connects SF6 pressure gauge and circuit breaker.
Described connecting hose is the anti-oxidant polyester flexible pipe of Teflon, and the first flexible pipe connects the SF6 steel cylinder by reduction valve, and the second flexible pipe one end connects the SF6 pressure gauge the other end by the Common Interface connecting breaker.
Described Common Interface is two-way check Common Interface, is provided with internal thread in it.The convenient circuit breaker that connects various models of Common Interface is set, increases its using scope.Common Interface is connected with the internal thread that is connected between the various model joints, and is convenient and reliable, workable.
Common Interface is the interior structure with internal thread with two-way return-stopping function.Only in circuit breaker self inside one inlet non return check valve is arranged because of existing making-up air device, when tonifying Qi, just might or come off because of inflatable interface place piping failure like this, and the SF6 gas that causes being inflated in the equipment under high pressure discharges rapidly, causes the excessively low danger situation of air chamber internal pressure to occur.Therefore two-way check Common Interface and with internal thread can improve the Security in the gas replenishment process.Solve the security incident that occurs because of shedding in the tonifying Qi process.
In gas replenishment process, the check formula SF6 density monitor Chang Zuowei reading foundation of breaker apparatus self, but present SF6 circuit breaker mostly is outdoor operation, long-play, exist the souvenir validity poor, descend easily, and can't check before the inflation maintenance, will there be the too high or too low risk of gas pressure in the tonifying Qi process, either way might causes breaker apparatus generation serious consequence in service.Therefore, the SF6 pressure gauge of setting up separately can Real Time Monitoring inflation pressure numerical value, and can be used for detecting the reading correctness of the SF6 pressure density table of SF6 circuit breaker self, thereby the normal operation of equipment is provided the reference frame of repair based on condition of component for converting equipment maintenance, operations staff.
The beneficial effect that the utility model has is: reasonable in design, simple in structure, can improve to greatest extent Security and the accuracy of SF6 inflation, and its using scope is wide, has good economic benefit.
