Description
Technical field:
The utility model relates to a kind of lapping device, particularly relates to the charged lapping device of a kind of New Type Isolating Switch contact fingertip, effectively can grind under not power-off condition to the contact probe fingering row of isolating switch.
Background technology:
The isolating switch used in power system, long-term to run in natural environment or in the stand-by state, the reasons such as contact probe abutment face can be soaked due to rainwater, environmental pollution, equipment material cause the aging phenomena such as contact surface oxidation, corrosion, thus moving contact and fixed contact of isolating switch Contact face contact resistance is sharply increased, under causing the larger load condition of isolating switch within rated value, contact surface seriously generates heat, and jeopardizes device security and normally runs.Conventional when processing the isolating switch heating defect caused because contact resistance is large, except needs are out of service by faulty equipment, also need the position residing in transformer substation system according to fault isolator, carry out corresponding grid switching operation, the equipment that stoppage in transit is relevant, and even whole service interval, is then ascended a height by maintainer and carries out hand lapping process, even needs isolating switch portion disintegrates to process.Not only power failure operation is complicated, and the time of troubleshooting is also long, is unfavorable for the continuity of power system to customer power supply.
Utility model content:
Technical problem to be solved in the utility model is: provide a kind of New Type Isolating Switch contact fingertip charged lapping device, can effectively grind isolation switch contact fingertip oxide layer at equipment live or under being in hot stand-by duty, improve the treatment effeciency of staff's fault.
The technical scheme that the utility model is taked for technical solution problem is:
The charged lapping device of a kind of New Type Isolating Switch contact fingertip, comprise handheld electrical machinery, hollow insulating bar, insulating driving rod, transmission support support, driving gear set, upper abrasive body, lower abrasive body and hold-down mechanism, described insulating driving rod be sleeved on described hollow insulating bar the inside, be connected with described handheld electrical machinery below, be connected with described driving gear set above, upper abrasive body described in described driving gear set drives and lower abrasive body opposite direction rotating, be provided with described hold-down mechanism between described upper abrasive body and lower abrasive body.
Described upper abrasive body and lower abrasive body be jointly arranged on one can be movable mounting base on, it is inner that described hold-down mechanism is positioned at described mounting base.
Described insulating driving rod is made up of solid epoxy plexiglas fiber, and described hollow insulating bar is insulating support rod; Described hollow insulating bar and the inside and outside coaxial installation of insulating driving rod, the insulated transmission part of the charged grinding system of the described 110kV isolating switch of common composition.
Positive beneficial effect of the present utility model is:
1, the utility model adopts two insulating bars cooperatively interacted as the major insulation of mill and main transmission section, and required power has the handheld electrical machinery of bottom to provide, after the driving gear set of installing through top drive two abrasive body opposite direction rotatings.Two abrasive bodies be jointly arranged on one can be movable mounting base on, enable abrasive body keep continual and steady grinding pressure to abradant surface by the hold-down mechanism of base interior.
2, insulated transmission part of the present utility model is that innovation of the present utility model is heavy, because of epoxy resin fiberglass material, office has insulating properties good, intensity is high, the advantage such as lightweight, therefore select this material as make insulated transmission regardless of main material, the final drive shaft of this part is made up of solid epoxy plexiglas fiber, hollow insulating bar and the inside and outside coaxial installation of insulating driving rod, the insulated transmission part of the charged grinding system of common composition described 110kV isolating switch, the insulating requirements of 110kV and following electric pressure livewire work no matter all can be met well from dielectric strength or mechanically actuated intensity.
3, the utility model can greatly shorten equipment power off time, improve the reliable and secure performance of electrical network, especially during summer peak meeting, power equipment can be made to meet the requirement of electrical network high load capacity phase continuous service to greatest extent, effectively ensure carrying out smoothly of summer peak meeting engineering.
4, the utility model is particularly useful for the transformer station of outdoor double bus scheme mode, effectively can reduce because bus isolating switch is oxidized because of contact probe abutment face the heating defect caused, ensure that continuity and the reliability of power supply to the full extent.
Accompanying drawing illustrates:
Fig. 1 is structural representation sketch of the present utility model.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further explained and illustrate:
See Fig. 1, the charged lapping device of a kind of New Type Isolating Switch contact fingertip, comprise handheld electrical machinery 1, hollow insulating bar 2, insulating driving rod 3, transmission support support 4, driving gear set 5, upper abrasive body 6, lower abrasive body 8 and hold-down mechanism 7, insulating driving rod 3 be sleeved on hollow insulating bar 2 the inside, be connected with handheld electrical machinery 1 below, be connected with driving gear set 5 above, driving gear set 5 drives upper abrasive body 6 and lower abrasive body 8 opposite direction rotating, between upper abrasive body 6 and lower abrasive body 8, be provided with hold-down mechanism 7.
