Abstract
The invention relates to a trolley for replacement of current transformers of centrally installed switchgears, and in particular to a trolley for replacement of a flip-chip current transformer of a centrally installed switchgear. The problems that in the prior art, people still have to enter a switch cabinet to replace flip-chip 10 kV current transformers, manpower and labor are wasted, working difficulty is high, and large potential safety hazards exist. The trolley comprises a fork arm lifting device fixed between a supporting platform and a base of the trolley, a hydraulic pump fixed on the fork arm lifting device, and a lifting handle connected with the hydraulic pump. The hydraulic pump is controlled through the lifting handle to drive the fork arm lifting device, the height of the supporting platform is controlled, and then the flip-chip current transformer of the centrally installed switchgear can be replaced. The trolley has multiple beneficial effects of being easy and convenient to operate, flexible to move, small in occupied space and the like, is applicable to complex working sites with narrow space, and completely meets rules of an electric power security working regulation. The trolley is applicable to replacement of conventional 10 kV current transformers and part of 10 kV voltage transformer in centrally installed switchgears.
Description
Technical field
The present invention relates to middle-placed switch cabinet current transformer and change dolly, be applicable to 10kV middle-placed switch cabinet flip-over type current transformer and more change jobs.
Background technology
In recent years, along with the power consumption of factories and miness, resident strengthens, original load can not meet original production, living needs, and changing 10kV current transformer operation quantity also increases year by year, and quite a few switch cubicle adopts current transformer inverted structure.Composition graphs 1, it is complicated that tradition changes flip-over type 10kV current transformer Job Operations, there is larger potential safety hazard, for our service work brings very large difficulty: specifically there is following shortcoming:
One, switch cubicle rear cabinet door narrow space, to carry out service work extremely inconvenient interior for service personnel, is easy to cause scratch, damage.
Two, 10kV current transformer quality is between 30kg-50kg, and it is very big that a people lifts difficulty, needs other staff to assist from side, and also do not get rid of the danger that current transformer has landing suddenly at work, there is larger potential safety hazard.
Three, for ensureing that current transformer is fixed, current transformer and support screw nargin less, service personnel is lifted for a long time could by lead screw and transformer screw to good, and consume personnel physical in a large number, more service work increases difficulty.
Four, through investigation display, change 10kV current transformer production time average out to 110min, operating personal is at least 3 people.Because the personnel's physical demands entered in switch cubicle is very big, in a upkeep operation, need to change number people and enter operation in cabinet.
Summary of the invention
The present invention carries out operation for the existing replacing middle-placed switch cabinet flip-over type 10kV operation of current transformers of solution still adopts personnel to enter in switch cubicle, there is labor intensive, muscle power, work difficulty is large and have larger security hidden trouble, provides a kind of dolly changing middle-placed switch cabinet flip-over type current transformer.
Change the dolly of middle-placed switch cabinet flip-over type current transformer, be included in fixation fork arm elevator apparatus between the support platform of dolly and base, Hydraulic Pump fixing on described yoke jacking system, the lifting handle be connected with described Hydraulic Pump; By lifting handle actuating hydraulic pump drive yoke jacking system, control the height of support platform, realize the replacing to middle-placed switch cabinet flip-over type current transformer.
At the upper surface of described support platform lower surface and base, horizontal guide rail is installed in the present invention, when Hydraulic Pump stretches, drives yoke jacking system to move on horizontal guide rail.
Further comprise dolly handrail in the present invention, described dolly handrail is arranged on the side of trolley base.Also comprise cardan wheel, described cardan wheel is fixed on trolley base lower surface, and wherein, the cardan wheel with brake that lower surface rear end is fixed, described yoke jacking system is interior scissor-type.
Principle of work of the present invention: dolly of the present invention adopts the driving of hydraulic pump system, drives yoke jacking system, realizes yoke lifting, and then controls the height of support platform; Trolley base top and support platform lower position are equipped with horizontal guide rail, when hydraulic ram stretches, pull scissors to pitch the interior outer support support upper and lower two groups of travelling wheels of beam body horizontal motion in orbit, prop up or fall support platform, both play the guiding role, also achieved the object that bay-lift rises and declines.
Beneficial effect of the present invention: the dolly of replacing middle-placed switch cabinet flip-over type current transformer of the present invention more changes jobs to 10kV current transformer, great reduction production time, promote work efficiency, actv. controls on-the-spot security risk, conscientiously ensure that and produces the actual person and the safety of equipment.Three aspects below imbody:
One, namely dolly application can be enterprise then and saves more than 17000 yuan, and number of work reduces to 2 people by original 3-4 and gets final product complete operation, effectively improves working efficiency, for enterprise saves human cost; For power-generating enterprise, safety is maximum economic benefit.This achievement actv. controls on-the-spot security risk, conscientiously ensure that and produces the actual person and the safety of equipment; Dolly of the present invention improves the work efficiency that 10kV current transformer is changed, and substantially reduces replacing production time, decreases the puzzlement that user causes because power off time is long.
Two, middle-placed switch cabinet current transformer change dolly have easy and simple to handle, mobile flexibly, take up an area the plurality of advantages such as space is little, be applicable to the operation field of complexity, narrow space, and meet electric power safety working regulation regulation completely.
Three, dolly of the present invention conventional 10kV current transformer and part 10kV voltage transformer can change operation in simultaneous adaptation middle-placed switch cabinet.
