Abstract
The utility model relates to a maintenance-free cover outside a main shaft of a drive part of a disconnecting switch of a transformer substation, particularly to a new maintenance-free cover suitable for the outside of the main shaft of the drive part of 66KVGW5-60 disconnecting switch (disconnecting link). The maintenance-free cover belongs to the field of electric power technology. The maintenance-free cover comprises a bolt and a cover, wherein the bolt is connected with the cover and goes through a top opening of the cover; specifically, a shallow groove is disposed at a bottom part of the cover, and a seal gasket is disposed inside the groove; and a groove is disposed at a bottom part of the bolt, and a seal washer is disposed inside the groove. Since a seal gasket and a seal washer are added, and the needle bearing part under the seal gasket is covered with a grease coating, the maintenance-free cover achieves effects of lubrication and protection against air, and is resistant to acid and alkali corrosion and rain erosion, so that the effects of being waterproof, dustproof, moistureproof, rustproof and corrosion-proof against acid and alkali are achieved. A problem of closing breakdown caused by rusty corrosion of the main shaft of the 66KV disconnecting switch (disconnecting link) drive device is completely overcome. The maintenance-free cover is suitable for wide electric power industry.
Description
Technical field
The utility model relates to the capping of substation isolating-switch running part main shaft external no-maintenance, relate in particular to a kind of outside novel maintenance-free capping of 66 KVGW5-60 of transformer station type isolating switches (disconnecting link) running part main shaft that is applicable to, belong to the power technology field, can solve the drawing fault that causes after the corrosion of 66KV isolating switch (disconnecting link) transmission mechanism main shaft.
Background technology
At present, 66KV transformer station of most of electric company at county level uses a large amount of 66KVGW5-60 type isolating switches (disconnecting link) in the electric power system northeastward, because the characteristics of northeast climate, make a clear distinction between the four seasons, spring, autumn, dust storm was bigger, summer rainwater is more, winter is then cold, easily frosting, freeze, make that the needle bearing in 66KV isolating switch (disconnecting link) the running part mainshaft mechanism makes moist easily, water inlet, get rusty, drawing can not draw away after the corrosion, have influence on normal operation and service work, we can say that time and the workload with nearly 70% handled this class fault in the annual inspection in spring and autumn of substation equipment maintenance and repair personnel.
Summary of the invention
The utility model provides the capping of a kind of substation isolating-switch running part main shaft external no-maintenance at above-mentioned problems of the prior art.Its objective is for a kind of moistureproof anti-corrosion, the significant non-maintaining capping of sealing property are provided.
The technical scheme that its technical problem that solves the utility model adopts is:
The capping of substation isolating-switch running part main shaft external no-maintenance comprises bolt and capping, and bolt passes to be filled out the capping open top and link together; Specifically be to be provided with groove in closure base portion, be provided with seal gasket in the groove; Described bolt bottom is provided with groove, is provided with O-ring seal in the groove.
The below of described seal gasket is provided with the lubricating grease coating.
The diameter of described capping is 2.7 ㎝, and internal diameter is 2.3 ㎝, and the height of capping 3 is 4.5 ㎜.
The thickness of described seal gasket 4 is 4.0 ㎜.
The groove of described bolt bottom is located at bolt root 1.4 ㎝ places, and the diameter of groove is 1.2 ㎝.
The thickness of described O-ring seal is 2 ㎜, and diameter is 1.2 ㎝.
The beneficial effects of the utility model are:
The utility model is owing to add O-ring seal and seal gasket, and lubricating grease is smeared at the needle bearing position below seal gasket, both played lubrication, again can secluding air, thereby can corrode by the resistance to acids and bases material, rainwater also is difficult to corrode simultaneously, has really played the effect that waterproof and dustproof, protection against the tide, anti-corrosion, anti-acid and alkali substance corrode, can thoroughly solve the drawing fault that causes after the corrosion of 66KV isolating switch (disconnecting link) transmission mechanism main shaft, be applicable to vast power industry.
The utility model also has following characteristics:
1. advanced: carrying out safety measure and having under the tutorial condition, installing can not have a power failure.
2. economy: reduced interruption duration, improved teams and groups' operating efficiency, the client has brought convenience with feeding, has increased benefit to power supply enterprise, has ensured power supply reliability.
3. time saving and energy saving non-maintaining, at least can 5 years non-maintaining.
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.

Among the figure: bolt 1, O-ring seal 2, capping 3, seal gasket 4, needle bearing 5, isolating switch drawing connecting lever 6, torque arm 7.
Embodiment
As Fig. 1-shown in Figure 12, the utility model is the capping of a kind of substation isolating-switch running part main shaft external no-maintenance, comprises bolt and capping, is to be passed by bolt to fill out the capping open top and link together, described capping 3 bottoms are provided with groove, are provided with seal gasket 4 in the groove; Described bolt 1 bottom also is provided with a groove, is provided with O-ring seal 2 in the groove; The below of described seal gasket 4 is provided with the lubricating grease coating.
Because the utility model is non-maintaining to be sealed on the basis of former capping and to have improved bolt and enclosing cover, and O-ring seal 2 and seal gasket 4 have been installed, one deck lubricating grease coating has been smeared at the needle bearing position again below seal gasket 4, both played lubrication, again can secluding air, thereby can corrode by the resistance to acids and bases material, rainwater also is difficult to corrode simultaneously.
Generally, connect torque arm 7 at the isolating switch drawing connecting lever 6 of 66KVGW5-60 type isolating switch (disconnecting link) running part main shaft by needle bearing 5.During concrete enforcement, be the capping 3 that adds a diameter 2.7 ㎝ at the top of isolating switch drawing connecting lever 6, the internal diameter of capping 3 is 2.3 ㎝, the height of capping 3 is 4.5 ㎜, and process a groove in capping 3 bottoms, and be with a seal gasket 4 in the groove simultaneously, the thickness of seal gasket 4 is 4.0 ㎜; Also process a groove at corresponding M6 hold-down bolt root 1.4 ㎝ places in addition, the diameter of groove is 1.2 ㎝, installing one O-ring seal 2 in the groove, and the thickness of O-ring seal 2 is 2 ㎜, and O-ring seal 2 diameters are 1.2 ㎝, and normal assembling both can.
