Abstract
The utility model discloses a fast maintenance tool for a tap switch of a transformer. The fast maintenance tool comprises a base; the base is composed of two vertical plates which are symmetrical left and right; a supporting rod is fixedly connected to the inner side surfaces of the two vertical plates in an upwards manner; the supporting rod is composed of an upper supporting rod and a lower supporting rod, both of which are cylindrical; the diameter of the lower supporting rod is larger than that of the upper supporting rod; the top end of the upper supporting rod is higher than that of a transformer casing pipe; a sleeve connecting part matched with a sleeve is arranged on the top end surface of the upper supporting rod in an upwards extending manner. During operation, the inner side surface of the base is propped against two parallel side surfaces of a fixing nut of the tap switch of the transformer, then the sleeve is sleeved at the sleeve connecting part, and the fixing nut of the tap switch of the transformer can be dismounted quickly by rotating a socket wrench, so that the tap switch can be inspected and repaired; besides, the top end of the upper supporting rod is higher than that of the transformer casing pipe, so that the socket wrench does not damage the transformer casing pipe while rotating.
Description
Technical field
The utility model relates to a kind of maintenance tool, particularly a kind of sub-connecting switch of transformer rapid-maintenance instrument.
Background technology
Along with expanding economy, the continuous of power consumption risen, and increasing transformer comes into operation.Expand with heat and contract with cold and loosening or sub-connecting switch of transformer cushion rubber aging that the heating of transformer can cause the sub-connecting switch of transformer hold-down nut, these all can cause the leakage of oil of transformer, cause transformer to damage.
Generally can use at present monkey wrench or laryngeal forceps to keep in repair, but owing to being subject to other part restriction spatially on transformer, the operating efficiency of this maintenance mode is lower, or easily damages other part on transformer.
See figures.1.and.2, bushing shell for transformer comprises transformer high-voltage bushing 1 and transformer low voltage sleeve pipe 2, sub-connecting switch of transformer 3 comprises the sub-connecting switch of transformer hold-down nut, the height of transformer high-voltage bushing 1 and transformer low voltage sleeve pipe 2 all is greater than the height of sub-connecting switch of transformer 3, monkey wrench or laryngeal forceps are very inconvenient when rotating the sub-connecting switch of transformer hold-down nut, will the maintenance of sub-connecting switch of transformer 3 be impacted like this, and easily damage the high-low pressure sleeve pipe.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of installation and removal that can complete fast the sub-connecting switch of transformer hold-down nut, the convenient sub-connecting switch of transformer rapid-maintenance instrument that shunting switch is overhauled.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of sub-connecting switch of transformer rapid-maintenance instrument, comprise the base that the side parallel with two of the sub-connecting switch of transformer hold-down nut connects, described base is comprised of symmetrical two risers, the medial surface of described two risers upwards is fixedly connected with support bar, described support bar is comprised of lower support bar and upper support bar, described lower support and upper support bar are cylindrical, the diameter of lower support bar is greater than the diameter of upper support bar, the top of described upper support bar is higher than the top of bushing shell for transformer, the top end face of upper support bar extends upward the sleeve connecting portion matched with sleeve.
In the utility model, described riser is bolted on support bar.
The beneficial effects of the utility model are: during work, allow the medial surface of base and two parallel side of sub-connecting switch of transformer hold-down nut connect, again jacket casing is connected on to sleeve connecting portion place, the rotational sleeve spanner can complete the dismounting of sub-connecting switch of transformer hold-down nut fast, then can carry out the maintenance of shunting switch.In addition, the top of described upper support bar is higher than the top of bushing shell for transformer, and box spanner just can not damage bushing shell for transformer when rotating.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the front view of transformer;
Fig. 2 is the top view of transformer;
Fig. 3 is front view of the present utility model;
Fig. 4 is left view of the present utility model;
Fig. 5 is top view of the present utility model.
The specific embodiment
As Fig. 3 ~ shown in Figure 5, a kind of sub-connecting switch of transformer rapid-maintenance instrument, comprise the base 11 that the side parallel with two of the sub-connecting switch of transformer hold-down nut connects, described base 11 is comprised of symmetrical two risers, the medial surface of described two risers upwards is fixedly connected with support bar 12, as of the present utility model preferred, described riser is bolted at support bar 12.Described support bar 12 is comprised of lower support bar 121 and upper support bar 122, described lower support bar 121 and upper support bar 122 are cylindrical, the diameter of lower support bar 121 is greater than the diameter of upper support bar 122, the top of described upper support bar 122 is higher than the top of bushing shell for transformer, and the top end face of upper support bar 122 extends upward the sleeve connecting portion 13 matched with sleeve.During work, allow the medial surface of base 11 and two parallel side of sub-connecting switch of transformer hold-down nut connect, again jacket casing is connected on to sleeve connecting portion 13 places, the rotational sleeve spanner can complete the dismounting of sub-connecting switch of transformer hold-down nut fast, then can carry out the maintenance of shunting switch.In addition, due to the top higher than bushing shell for transformer, the top of upper support bar 122, after being connected on jacket casing on sleeve connecting portion 13, box spanner just can not damage bushing shell for transformer when rotating.
The above, be preferred embodiments of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
