Abstract
The present invention relates to the capping of substation isolating-switch running part main shaft external no-maintenance, particularly relate to one and be applicable to the outside novel maintenance-free capping of transformer station 66 KVGW5 60 type disconnecting switch (disconnecting link) running part main shaft, belong to technical field of electric power.The present invention includes bolt and capping, and bolt links together through filling out capping open top；Specifically it is provided with groove in closure base portion, in groove, is provided with seal gasket；Stud base is provided with groove, is provided with O-ring seal in groove.Due to the fact that and install O-ring seal and seal gasket additional, below seal gasket, grease coating is smeared at needle bearing position, both lubrication had been played, completely cut off again air, resistance to acids and bases material corrodes, and makes rainwater be difficult to corrode, and serves waterproof and dustproof, protection against the tide, anti-corrosion, the effect of anti-acid and alkali substance corrosion, the drawing fault caused after thoroughly solving the main shaft corrosion of 66KV disconnecting switch (disconnecting link) drive mechanism, it is adaptable to vast power industry.
Description
Technical field
The present invention relates to the capping of substation isolating-switch running part main shaft external no-maintenance, particularly relate to one and be applicable to the outside novel maintenance-free capping of transformer station 66 KVGW5 60 type disconnecting switch (disconnecting link) running part main shaft, belong to technical field of electric power, the drawing fault caused after the main shaft corrosion of 66KV disconnecting switch (disconnecting link) drive mechanism can be solved.
Background technology
At present, most of electric company's 66KV application in substations substantial amounts of 6,6KV,GW5 60 type disconnecting switch (disconnecting link) at county level in power system northeastward, feature due to northeast climate, make a clear distinction between the four seasons, spring, autumn, dust storm was bigger, summer rainwater is more, winter is the coldest, easily frosting, freeze, needle bearing in 66KV disconnecting switch (disconnecting link) running part mainshaft mechanism is easily made moist, water inlet, get rusty, after corrosion, drawing can not draw away, have influence on normal operation and service work, it may be said that substation equipment maintenance and repair personnel are processing this kind of fault by time and the workload of nearly 70% in examining annual spring and autumn.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, it is provided that a kind of substation isolating-switch running part main shaft external no-maintenance capping.Its purpose is to provide a kind of moistureproof anti-corrosion, the significant non-maintaining capping of sealing property.
The technical solution adopted for the present invention to solve the technical problems is:
Substation isolating-switch running part main shaft external no-maintenance covers, and including bolt and capping, bolt links together through filling out capping open top；Specifically it is provided with groove in closure base portion, in groove, is provided with seal gasket；Described stud base is provided with groove, is provided with O-ring seal in groove.
The lower section of described seal gasket is provided with grease coating.
A diameter of the 2.7 of described capping, 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 stud base is located at bolt root 1.4, a diameter of the 1.2 of groove.
The thickness of described O-ring seal is 2, a diameter of 1.2.
The invention has the beneficial effects as follows:
Due to the fact that and add O-ring seal and seal gasket, and smear grease at the needle bearing position, lower section of seal gasket, both lubrication had been played, air can be completely cut off again, being thus able to the corrosion of resistance to acids and bases material, rainwater is also difficult to corrode simultaneously, really serves waterproof and dustproof, protection against the tide, anti-corrosion, the effect of anti-acid and alkali substance corrosion, the drawing fault caused after can thoroughly solving the main shaft corrosion of 66KV disconnecting switch (disconnecting link) drive mechanism, it is adaptable to vast power industry.
The present invention also has the following characteristics that
1. advanced: carry out safety measure and have tutorial under the conditions of, can not have a power failure installing.
2. economy: decrease power off time, improves teams and groups' work efficiency, brings conveniently with feeding client, adds benefit to power supply enterprise, ensured power supply reliability.
The most time saving and energy saving non-maintaining, at least can be non-maintaining with 5 years.
The present invention is further detailed explanation with specific embodiment below in conjunction with the accompanying drawings.

Detailed description of the invention
As shown in Fig. 1-Figure 12, the present invention is a kind of substation isolating-switch running part main shaft external no-maintenance capping, including bolt and capping, is to be linked together through filling out capping open top by bolt, it is provided with groove bottom described capping 3, in groove, is provided with seal gasket 4；It also is provided with a groove bottom described bolt 1, in groove, is provided with O-ring seal 2；The lower section of described seal gasket 4 is provided with grease coating.
Bolt and enclosing cover is improved be sealed on untouched lid owing to the present invention is non-maintaining on the basis of, and installed O-ring seal 2 and seal gasket 4, below seal gasket 4, one layer of grease coating has been smeared again at needle bearing position, both lubrication had been played, air can be completely cut off again, being thus able to the corrosion of resistance to acids and bases material, rainwater is also difficult to corrode simultaneously.
Under normal circumstances, the disconnecting switch drawing connecting lever 6 at 6,6KV,GW5 60 type disconnecting switch (disconnecting link) running part main shaft connects torque arm 7 by needle bearing 5.When being embodied as, being the capping 3 adding a diameter 2.7 at the top of disconnecting switch drawing connecting lever 6, the internal diameter of capping 3 is 2.3, the height of capping 3 is 4.5, and bottom capping 3, process a groove, simultaneously band one seal gasket 4 in groove, the thickness of seal gasket 4 is 4.0；Additionally also processing a groove at corresponding M6 hold-down bolt root 1.4, a diameter of the 1.2 of groove, installing one O-ring seal 2 in groove, the thickness of O-ring seal 2 is 2, and O-ring seal 2 a diameter of 1.2, normal assembling both may be used.
Institute's example body size in the present embodiment, it is also possible to strengthen according to required capping and the size of corresponding bolt or reduce, is not limited, all within scope by size of illustrating in the present embodiment.
