Description
Technical field
The present invention relates to a kind of electric equipment maintenance aid, relate in particular to a kind of overhaul platform of circuit breaker.
Background technology
At present; the NXAIR type vacuum switchgear of Siemens Company has been widely used in electric power system, this switchgear integrate cut-off, isolation, ground connection and interlock, and there is perfect monitoring, control and protection function; therefore, it has become the important component part of electrical network.
What in above-mentioned switchgear, install is a kind of removable circuit breaker, and in actual moving process, this circuit breaker is pushed in switch cubicle, is steadily placed on supporting guide, after circuit breaker and switch cubicle are tightened, can normally work.There is not the body chassis that is similar to common VD4 or VS1 circuit breaker in this circuit breaker, therefore, in order to realize the normal service work of this class circuit breaker, manufacturer also needs 3 service kits of special configuration, 1 that is:, propelling trolley, for realizing, circuit breaker is taken out or realizes contrary operation in switch cubicle; 2, guiding chassis, for ensureing that propelling trolley is reposefully from switchgear external movement to switchgear inside; 3, hydraulic lift truck, is transported to ground by circuit breaker from propelling trolley for realizing.
But, in long-term operation maintenance process, find following problem:
1,, in breaker transfer process, need to use propelling trolley to do middle transhipment, and then utilize hydraulic lift truck after circuit breaker, circuit breaker to be placed into the storage platform of ground or level altitude; Must increase like this step of operation, increase the time of maintenance.
2, because circuit breaker contacts by face with guide rail in cabinet, more painstaking in the time extracting circuit breaker or inverse operation with propelling trolley out from switch cubicle, propelling trolley serious wear.
3, in transport process, propelling trolley insertion is exited circuit breaker or inverse operation, because propelling trolley exclusive guideway exists certain gradient and propelling trolley center of gravity in transhipment circuit breaker process higher, and propelling trolley does not arrange safe locking device, therefore there is very large potential safety hazard in this operation.
4, hydraulic lift truck structurally, is arranged on hydraulic chain driving mechanism on center line, phenomenon that will inevitably run-off the straight in the time of circuit breaker deviation of gravity center axis, and taking off circuit breaker from hydraulic pressure transferring platform to propelling trolley has increased difficulty.
5, with propelling trolley by circuit breaker when hydraulic lift truck takes off, highly have stricter requirement for the adjusting of hydraulic lift truck, need to repeatedly adjust, wasted the repair time; In addition,, because hydraulic lift truck adopts hydraulic driving mode, be in height also not easy to do small adjustment.
6, because operation is more loaded down with trivial details, if operating personnel's technology is not very consummate, technical key point is grasped not thorough, and operating efficiency can be very low; For the sake of security, this inspection platform is also not suitable for a people and carries out separately upkeep operation.
7, in the case of the surface water Pingdu in transformer station be not very high, very likely there is security incident in this transfer tool.
8,, in maintenance process, existing service kit has higher requirements to operating personnel's muscle power.
9, not obvious when propelling trolley being pushed to lead when the inner guide effect on chassis of switchgear, car wheel often collides with guide rail base plate; All propelling trolley wheels all have the vestige of significantly wounding, and surface is rough, and running stability reduces.
In sum, the service kit of above-mentioned this removable circuit breaker not only quantity is too much, operate very inconvenient, and also very dangerous, muscle power and experience to operating personnel are all had relatively high expectations; In addition, existing service kit, after use after a while, damages obviously, thereby has great potential safety hazard.Therefore,, in view of the service kit of above-mentioned removable circuit breaker exists complex operation, effort, the problems such as safe and reliable not, nowadays meet real needs in the urgent need to developing a kind of new workable inspection platform.
Summary of the invention
