Abstract
The utility model discloses a lifting tool for fueling operation of a current transformer. The lifting tool comprises a supporting angle iron and two lead screws, wherein the two parallel lead screws pass through the supporting angle iron and are vertical to the supporting angle iron; and nuts are arranged at the upper parts of the two lead screws. The lifting tool has a simple structure, is convenient to use, greatly shortens the lifting time of corrugated plates and is safe and reliable.
Description
Technical field
The utility model belongs to the service equipment technical field of high-tension power transmission and transformation equipment, especially relates to a kind of current transformer fueling operation and uses the lifting instrument.
Background technology
Oil-immersed current transformer is widely used in electric power system, and after the long-time running, the insulating oil oil level in it can decline to a great extent, and need carry out repairing to it; The general operation step is after oil-immersed current transformer has a power failure, to open corrugated expander shell; Through manpower lifting corrugated plate, rising height is laid down greater than 15cm; Open the drain tap on the expander then, from drain tap to the current transformer oiling, because artificial rising height is not easy to grasp; And the general oiling time is longer, has therefore increased the time of work high above the ground, has increased the danger of work high above the ground.
Summary of the invention
For addressing the above problem, the purpose of the utility model provides a kind of current transformer fueling operation and uses the lifting instrument.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of current transformer fueling operation is used the lifting instrument, and it comprises support angle steel and two rhizoid bars, and two parallel screw mandrels pass the support angle steel, and vertical with the support angle steel, and two rhizoid bar tops all are equipped with a nut.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
This current transformer fueling operation is used the lifting instrument, and it is simple in structure, and is easy to use, has shortened the corrugated plate lifting time greatly, and is safe and reliable, and result of use is good.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1 (a, b)-screw mandrel; 2 (a, b)-nuts; 3-supports angle steel; 4-expander shell; The 5-corrugated plate; The 6-oil filler point.
Embodiment
Through accompanying drawing and embodiment the utility model is done further explain below.
As shown in Figure 1; This current transformer fueling operation is used the lifting instrument; It comprises support angle steel and two rhizoid bars, supports on the angle steel 3 and offers two lifting holes with spacing, and two parallel screw mandrel 1a, screw mandrel 1b pass the lifting hole of supporting on the angle steel 3; And angle steel is vertical with supporting, and screw mandrel 1a, screw mandrel 1b top are separately installed with nut 2a, nut 2b.
When the described lifting instrument of the utility model uses, support angle steel 3 and lie in a horizontal plane in expander shell 4 tops, two parallel screw mandrel 1a, screw mandrel 1b lower ends are threaded with corrugated plate 5 tops; Twist nut 2a, nut 2b clockwise with spanner; Nut 2a, nut 2b move downward extruding and support angle steel 3, are placed on the expander shell owing to support angle steel, can not move downward; Therefore screw mandrel 1a, screw mandrel 1b are moved upward; Screw mandrel drives corrugated plate 5 and rises, and corrugated plate is risen to correct position, and the corrugated plate hoisting depth is 10 ~ 15cm; Oil filling pipe is connected with oil filler point 6 on the corrugated plate 5, can in corrugated plate, refuels, accomplish the fueling operation of current transformer.
