Abstract
The utility model relates to a mounting and dismounting tool for a current transformer of high tension switchgear and relates to the technical field of machine manufacture. The mounting and dismounting tool comprises left and right protection plates. One end of each protection plate is hinged with a jack by a bolt. The middle part of each protection plate is hinged with a bracing frame by a rotating shaft. The other end of the bracing frame is hinged with one end of a propping rod. The upper part of the other end of the bracing frame is provided with a gap and hinged with a bushing by a shaft. The upper end of the bushing is provided with a fixing plate. The other end of the propping rod is connected with a piston rod of the jack. The tool of the utility model can solve the problems that the mounting and dismounting of the current transformer in the switchgear is time-consuming and labor-consuming, causing the power failure time to be too long and affecting the normal production and life of people.
Description
Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of device of changing current transformer in switch cubicle.
Background technology
As everyone knows, many electric components are installed in electrical switchgear, wherein current transformer belongs to build greatly and the heavier a kind of electric component of weight, current transformer in past electrical switchgear burns out while needing to change, need cut off the electricity supply, remove old current transformer and change new current transformer; While wherein removing old current transformer, need a people to fix current transformer, another person unclamps set bolt, remove and connect after wire, slowly old current transformer is removed again, then new current transformer is put into position and tights a bolt again, connect wire, so far, change current transformer process and finish; Due to current transformer comparatively heaviness and also electrical switchgear locus limited, changing primary current instrument transformer comparatively wastes time and energy, probably need to spend seven, eight hours even more, so just cause interruption duration long, affect that people are normal to produce and life.
Summary of the invention
The object of this invention is to provide a kind of dismantling device of high-tension switch cabinet current transformer, it can solve prior art and in switch cubicle, change current transformer and waste time and energy, and the overlong time that causes power failure affects that people are normal to produce and the problem of life.
In order to address the above problem, the technical solution used in the present invention is:
A kind of dismantling device of high-tension switch cabinet current transformer, comprise two backplates in left and right, there is jack one end of described backplate by bolted splice, the middle part of described backplate is hinged by one end of rotating shaft and bracing frame, the other end of support frame as described above and one end of push rod are hinged, and the top of the other end of described support bar is provided with breach, and hinged by axle and sleeve pipe, the upper end of described sleeve pipe is provided with fixed head, and the other end of described push rod is connected with the piston rod of described jack.
In above technical scheme, further scheme is: the both sides of described backplate one end are provided with wheel by wheel shaft, in described backplate, are provided with reinforcing prop.
Further: described sleeve pipe and fixed head are spirally connected.
Further: described push rod is " U " type, and its left and right opening part is hinged on the left and right sides of described support bar.
Further: described backplate is provided with fixing ear near the left and right, both sides of one end of described jack.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, adopt the dismantling device of high-tension switch cabinet current transformer of the present invention, can, by regulating jack piston rod extension elongation, control the lifting height of fixed head, make easily to need the current transformer of changing to rest on any position;
2, adopt the dismantling device of high-tension switch cabinet current transformer of the present invention for changing the current transformer in switch cubicle, whole process can shorten one times of time.
