The utility model discloses transformer bushing general cap dismantles isolated plant, can conveniently dismantle transformer bushing general cap, improves work efficiency, shortens repair time, reduces maintainer intensity of labour and operation risk moreover.
Description
Technical Field
The utility model relates to a extracting tool specifically is a transformer bushing is with army cap dismantles isolated plant.
Background
The top of the high-voltage bushing of the power transformer is commonly called as a general cap, which is an important link for electric energy transmission between the inside and the outside of the transformer and is also a necessary device for sealing and isolating transformer oil in the transformer from the outside. Some newly-put-into-service transformers are not provided with special devices for fastening the military caps, so that the phenomenon of loosening the military caps is frequently caused, once the transformers are loosened, direct-current resistance exceeds standard and generates heat, transformer oil at a sealing part leaks, and meanwhile, moisture and air can permeate to influence the quality of the transformer oil, so that safe and stable operation of a power grid and equipment of the power grid is influenced. When various overhauls are carried out to the transformer, if handle high-voltage bushing outside binding post and generate heat, "general cap" oil seepage, main transformer overhaul, demolish sleeve pipe etc. all need to dismantle, fasten general cap. At present when dismantling transformer general cap, need stretch into general cap flange with the large-size spanner to the joint just can dismantle on the screw rod, because the clearance between the flange is less, and large-size spanner can't stretch into, and the forced operation can make the flange damage and reduce its sealing performance.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a transformer bushing general cap dismantles isolated plant is provided, can conveniently dismantle transformer bushing general cap, improves work efficiency, shortens repair time, reduces maintainer intensity of labour and operation risk moreover.
The utility model discloses solve above-mentioned technical problem with following technical scheme:
the utility model discloses isolated plant is dismantled to transformer bushing general cap, it includes the handle, the front end of handle is equipped with and is relative to the slow-witted board lip and the movable plate lip that set up, the front end of slow-witted board lip and movable plate lip is equipped with the pothook of symmetrical setting, the bottom and the handle fixed connection of slow-witted board lip, the bottom cover of movable plate lip is on the pivot, and the bottom of movable plate lip forms screw-thread fit with the turbine of installing on the handle, through rotating the turbine, make the movable plate lip along pivot lateral shifting, form the opening that can block transformer bushing general cap between slow-witted board lip and the movable plate lip, and the opposite side of slow-up lip and movable plate lip sets up to the zigzag structure.
The fixed plate lip and the movable plate lip are made of alloy structural steel, the thickness of the fixed plate lip and the movable plate lip is 4-6mm, and the moving stroke of the movable plate lip is 70 mm.
The bottom outer wall of the movable plate lip is provided with scales.
Use the utility model discloses the device is dismantled the transformer with military cap, can reduce maintainer intensity of labour and operation risk to a certain extent, shortens maintenance time, improves work efficiency, has very strong practicality.
Drawings
Fig. 1 is a schematic structural diagram of the special device for disassembling the military cap by the transformer bushing of the present invention.
Detailed Description
As shown in fig. 1, the utility model discloses transformer bushing dismantles isolated plant with military cap includes handle 3, the front end of handle 3 is equipped with and is relative to the solid plate lip 2 and the activity plate lip 1 that set up, the front end of solid plate lip 2 and activity plate lip 1 is equipped with the symmetrical pothook that sets up, the bottom and the 3 fixed connection of handle of solid plate lip 2, the bottom cover of activity plate lip 1 is on pivot 5, and the bottom of activity plate lip 1 forms screw-thread fit with the turbine 4 of installing on the handle, through rotating turbine 4, it makes it transversely remove about pivot 5 to drive the activity plate lip, form the opening that can block transformer bushing with military cap between solid plate lip 2 and the activity plate lip 1, and solid plate lip and activity plate lip opposite side set up to the zigzag structure.
Because of the particularity of the working position of the utility model, the rigid plate lip 2 and the movable plate lip 1 are made of alloy structural steel, the thickness of the rigid plate lip is 4-6mm, and the moving stroke of the movable plate lip is 70 mm.
The bottom outer wall of activity board lip 1 is provided with the scale to its concrete stroke data that remove of convenient record.
During the use, will the utility model discloses transformer bushing general cap dismantles isolated plant stretches into the bottom of transformer bushing general cap to going into the cylindrical slot of general cap with the pothook card of staying board lip 2 and activity board lip 1, then through rotating turbine 4, make staying board lip and activity board lip bite tightly general cap, thereby pull general cap very easily, accomplish the dismantlement operation.
Claims (1)
