Abstract
The utility model discloses an antirust 35KV isolating switch and belongs to the transformer substation equipment maintenance technology field. An outer sleeve and a shell are sealed through a waterproof sealant. The shell and a steel cushion located between the shell and a bearing are sealed through an oil-resistant sealant. A top of the shell is provided with an oil injection nozzle. The oil injection nozzle is connected with an oil injection channel. The oil injection channel passes through the shell and the steel cushion, then directly faces the bearing and is connected with a shaft sleeve chamber. According to the switch of the utility model, through waterproof sealing between the outer sleeve and the shell, and oil-resistant sealing between the shell and the steel cushion, water, moisture and the like are prevented from entering into an internal portion of the isolation switch so that corrosion of an universal driving shaft, the bearing and the like is effectively avoided; simultaneously, through the oil injection nozzle, lubricating oil can be conveniently added into a shaft sleeve so that the operation of the isolation switch is flexible and a rust condition is avoided; during an overhauling and maintenance process, only the lubricating oil needs to be added into the shaft sleeve so that a maintenance amount of the isolation switch is effectively reduced and a maintenance period is prolonged.
Description
Technical field
The utility model relates to substation equipment maintenance technology field.
Background technology
Along with the development of electric utility, a large amount of electric equipments drops into and is applied in electrical network, and appliance maintenance maintenance workload is increasing.GW35 outdoor high-voltage isolating switch, be mainly used in high pressure line interval, be applicable to exchange 50Hz, in the electric power system of rated voltage 35KV, as having in the zero load situation of voltage, coordinate with on-load switch, the switchgear of breaking and closing circuit uses, and is one of a large amount of power equipments that use in electric power system.
Because the universal driving shaft of GW35 outdoor high-voltage isolating switch and base adopt metal material to make more, and mostly use out of doors, stand wind and weather throughout the year, suffer after the invasion and attack of rainwater, its rotating part is bad because of the sealing of bearing place, intakes, enters the former thereby corrosions such as moisture, make switch when rotating and viscous motion, malfunctioning, when console switch, easily cause to refuse to draw or refuse and close, when serious, arc short-circuit occurs in operating process and initiating failure, thereby have a strong impact on the normal operation of electric power system.And generally the GW35 outdoor high-voltage isolating switch overhaul life short, power failure difficulty is large, the human and material resources that overhaul once drops into are more, the area that has a power failure during overhaul is large, economic loss and social influence are very large.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rust-proof type 35KV isolating switch, can anti-sealing, moisture etc. enters isolating switch inside, effectively avoid isolating switch corrosion, simultaneously easily to apply oil in axle sleeve, make isolator operation flexible, the dead phenomenon of avoiding becoming rusty occurs, and effectively alleviates the maintenance of isolating switch, save the repair and maintenance time, extend maintenance period.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A rust-proof type 35KV isolating switch, comprise base, universal driving shaft, axle sleeve, be positioned at axle sleeve top shell and overcoat, bearing and sector gear, it is characterized in that with waterproof gasket cement, sealing between described overcoat and shell; Described shell and adopt oil resistant sealant sealing between the steel pad between shell and bearing;
Described cover top portion is provided with pump nozzle, and pump nozzle connects oiling passage, oiling passage through shell and steel pad after over against bearing, and communicate with axle sleeve chamber;
Between described overcoat and shell, seal the waterproof gasket cement preferred acidic silicone glass cement of use;
The preferred room temperature vulcanization silicone of oil resistant fluid sealant that seals use between described shell and steel pad is exempted from gasket seal glue.
The beneficial effect that adopts technique scheme to produce is: the utility model seals by the oil resistant of the waterproof sealing between overcoat and shell, shell and steel pad, and anti-sealing, moisture etc. enter isolating switch inside, effectively avoids the corrosions such as universal driving shaft, bearing; Simultaneously by pump nozzle easily to apply oil in axle sleeve, make isolator operation flexible, the dead phenomenon of avoiding becoming rusty occurs; In repair and maintenance process, only need in axle sleeve, refuel, reduce the maintenance of isolating switch, save the repair and maintenance time, extend maintenance period.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein, 1, base, 2, overcoat, 3, pump nozzle, 4, oiling passage, 5, bearing, 6, axle sleeve, 7, universal driving shaft, 8, sector gear, 9, steel pad, 10, shell.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of rust-proof type 35KV isolating switch, comprise base 1, universal driving shaft 7, axle sleeve 6, be positioned at axle sleeve 6 tops shell 10 and overcoat 2, bearing 5 and sector gear 8;
Wherein, between overcoat 2 and shell 10, with acid silicone glass waterproof gasket cement, seal;
Shell 10 and adopt room temperature vulcanization silicone to exempt from gasket seal glue between the steel pad 9 of 5, shell 10 and bearing to seal;
Shell 10 tops are provided with pump nozzle 3, and pump nozzle 3 connects oiling passages 4, oiling passage 4 through shell 10 and steel pad 9 after over against bearing 5, and communicate with axle sleeve 6 chambers.
When the utility model is used, at the overcoat of isolating switch and carry out waterproof sealing, shell and the steel pad between shell, carry out oil resistant sealing, prevent that water around, moisture etc. from entering isolating switch axle sleeve inner, effectively avoid the corrosions such as universal driving shaft, bearing; Simultaneously by pump nozzle to apply oil in axle sleeve, make isolator operation flexible, the dead phenomenon of avoiding becoming rusty occurs; In repair and maintenance process, only need in axle sleeve, refuel, the isolating switch repair and maintenance time is short, and maintenance period is long.
