Abstract
The utility model discloses isolating switch base self-lubricating axle sleeve, comprise packing sleeve, it is characterized in that: in the side walls of described packing sleeve, symmetry is fixed with two nuts, be threaded connection in each nut and be fixed with screw rod, the front center of screw rod is provided with cavity, is embedded in graphite block at cavity.The utility model structure is simple, with low cost, replacing is convenient, when isolating switch carries out breaking-closing operating, self-lubricating can be carried out along with the rotation of base bearing ball, ensure that the reliable divide-shut brake of isolating switch, avoid to occur because bearing lacks lubrication jam, cannot the phenomenon of normal divide-shut brake, decrease the time of interruption maintenance, improve the efficiency of service work and the economic benefit of enterprise.
Description
Technical field
The utility model relates to a kind of lubricating arrangement of outdoor disconnector base bearing, a kind of isolating switch base self-lubricating axle sleeve specifically, be arranged on Outdoor Trusses For Transformer Substation isolating switch base bearing and use, when carrying out breaking-closing operating, bearing completes self-lubricating while rotating, and avoids bearing jam.
Background technology
Isolating switch is one of high voltage electric equipment that in electric power system, use amount is maximum, range of application is the widest.Carry out isolation circuitry when grid power blackout, equipment rebuilding by isolating switch breaking-closing operating, form obvious visible air insulation clearance, ensure the person, device security.The divide-shut brake of isolating switch relies on electronic or manual-operating mechanism to drive drive link, and drive link drives datum axle to forward to have moved by connecting rod.The lubricating oil of bearing is solid, volatilization easily, and base cannot oil injecting lubricating, adds the erosion of external condition, easy corrosion and jam, causes the tripping of isolating switch divide-shut brake, increase the interruption maintenance time, incur loss through delay carrying out of interruption maintenance work.
Summary of the invention
The purpose of this utility model be to provide a kind of structure simple, with low cost, change convenient, when service work needs isolating switch to carry out breaking-closing operating, effectively can carry out base bearing self-lubricating, guarantee that isolating switch can the isolating switch base self-lubricating axle sleeve of reliability service.
In order to reach above object, the technical scheme that the utility model adopts is: this isolating switch base self-lubricating axle sleeve, comprise packing sleeve, it is characterized in that: in the side walls of described packing sleeve, symmetry is fixed with two nuts, be threaded connection in each nut and be fixed with screw rod, the front center of screw rod is provided with cavity, is embedded in graphite block at cavity.
The diameter 4mm of described graphite block, long 6mm; The diameter 6mm of described screw rod, long is 7mm; Described nut specification is φ 8, and thickness is 4mm.
The beneficial effects of the utility model are: structure is simple, with low cost, replacing is convenient, when isolating switch carries out breaking-closing operating, self-lubricating can be carried out along with the rotation of base bearing ball, ensure that the reliable divide-shut brake of isolating switch, avoid to occur because bearing lacks lubrication jam, cannot the phenomenon of normal divide-shut brake, decrease the time of interruption maintenance, improve the efficiency of service work and the economic benefit of enterprise.
Accompanying drawing explanation
Fig. 1 is structure schematic top plan view of the present utility model.
Fig. 2 is the structure cross-sectional schematic along Figure 1A-A of the present utility model.
In figure: 1, packing sleeve; 2, nut; 3, screw rod; 4, graphite block.
Embodiment
The utility model is made with reference to Fig. 1, Fig. 2.This isolating switch base self-lubricating axle sleeve, comprise packing sleeve 1, it is characterized in that: in the side walls of described packing sleeve 1, symmetry is fixed with two nuts 2, be threaded connection in each nut 2 and be fixed with screw rod 3, the front center of screw rod 3 is provided with cavity, is embedded in graphite block 4 at cavity.
The diameter 4mm of described graphite block 4, long 6mm; The diameter 6mm of described screw rod 3, long is 7mm; Described nut 2 specification is φ 8, and thickness is 4mm.
During use, under this utility model being installed at isolating switch base bearing, the position of graphite block 4 is within the bearing immediately below ball, when isolating switch carries out breaking-closing operating, in bearing, ball pivoting friction graphite block 4 carries out self-lubricating, graphite levels can be checked according to isolator operation number of times during daily tour equipment, treat that graphite is finished, take off screw rod 3 and change graphite block 4.
