Abstract
The utility model discloses an insulating spanner for maintaining a transformer. The insulating spanner for maintaining the transformer comprises a double-end spanner, wherein the double-end spanner comprises spanner heads at the two ends and a middle handle, the spanner heads can be respectively applied to bolts of different specifications, an inner elastic insulating layer and an outer elastic insulating layer are arranged on the double-end spanner in a sleeved mode from inside to outside, the inner elastic insulating layer and the outer elastic insulating layer are respectively provided with a sleeve pipe capable of tightening a handle in a sleeved mode and an opening capable of wrapping each spanner head, the opening of the inner elastic insulating layer and the opening of the outer elastic insulating layer wrap the spanner heads at the two ends of the double-end spanner respectively, and the double-end spanner can move in the inner elastic insulating layer. By means of the insulating spanner for maintaining the transformer, a worker repairing the transformer can carry out operation safely even when not wearing insulating gloves, therefore, the work efficiency and operation safety are improved, and the cost of enterprises is lowered to a certain extent.
Description
Technical field
The utility model relates to a kind of insulating tool, particularly relates to a kind of transformer and safeguards the Insulation spanner of use.
Background technology
In the transformer maintenance process, the most frequently used instrument is mainly spanner.Because transformer itself is a power storage body, so with voltage, and the insulation effect of the insulating barrier of existing Insulation spanner outer surface is desirable not enough, do not reach the standard of safety work, therefore maintenance mans must wear insulating glove and just can carry out maintenance operation, can affect the flexibility of operation by human hand but wear insulating glove, thereby reduce operating efficiency,, due to the limited easy damage of the hardness of insulating glove, can not guarantee the security that maintenance mans operate simultaneously.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of insulating properties reliable, simple in structure, easy to use, is used for the Insulation spanner that transformer is safeguarded.
The technical solution of the utility model is:
a kind of transformer is safeguarded the Insulation spanner of use, comprise double (end) wrench, described double (end) wrench comprises that two ends are applied to respectively driving end and the middle handle of the bolt of different size, described double (end) wrench is set with interior elastic insulating layer from inside to outside, outer elastic insulating layer, the sleeve pipe and one that described interior elastic insulating layer and outer elastic insulating layer include the handle that can be locked can coat the opening of driving end, the opening of described interior elastic insulating layer and outer elastic insulating layer coats the driving end of double (end) wrench one end separately, described double (end) wrench can move in interior elastic insulating layer, and only expose the wherein driving end of an end, maintenance mans can avoid touching the driving end of the other end and get an electric shock when operation like this.
Further, be provided with the PVC layer between described interior elastic insulating layer and outer elastic insulating layer.Described PVC layer can improve the hardness of interior elastic insulating layer and outer elastic insulating layer on the one hand, makes them be not easy to be scratched damage by metalwork; Outer elastic insulating layer can be moved freely to the both-end of double (end) wrench, the driving end at double (end) wrench two ends can be used, increase the workability of double (end) wrench.
Further, described driving end is opened wrench head.
The beneficial effects of the utility model are: a kind of transformer that the utility model adopts is safeguarded the Insulation spanner of use, and it comprises interior elastic insulating layer, PVC layer, the three-layer insulated protection structure of outer elastic insulating layer, has good insulating reliability energy.Even the staff of maintenance transformer does not wear insulating glove, also can carry out safety operation, therefore, improved the security of operating efficiency and operation, also reduced the cost of enterprise on certain degree.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and example.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the another kind of occupation mode of the utility model.
The specific embodiment
with reference to Fig. 1, Fig. 2, a kind of transformer of the present utility model is safeguarded the Insulation spanner of use, comprise double (end) wrench 1, described double (end) wrench 1 comprises that two ends are applied to respectively driving end and the middle handle of the bolt of different size, described double (end) wrench 1 is set with interior elastic insulating layer 2 from inside to outside, outer elastic insulating layer 3, the sleeve pipe and one that described interior elastic insulating layer 2 and outer elastic insulating layer 3 include the handle that can be locked can coat the opening of driving end, the opening of described interior elastic insulating layer 2 and outer elastic insulating layer 3 coats the driving end of double (end) wrench 1 one ends separately, described double (end) wrench 1 can be in the interior movement of interior elastic insulating layer 2, and only expose the wherein driving end of an end, maintenance mans can avoid touching the driving end of the other end and get an electric shock when operation like this.
Further, be provided with the PVC layer between described interior elastic insulating layer 2 and outer elastic insulating layer 3.Described PVC layer can improve the hardness of interior elastic insulating layer 2 and outer elastic insulating layer 3 on the one hand, makes them be not easy to be scratched damage by metalwork; Outer elastic insulating layer 3 can be moved freely to the both-end of double (end) wrench 1, the driving end at double (end) wrench 1 two ends can be used, increase the workability of double (end) wrench 1.
Further, described driving end is opened wrench head.
The above, be preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned embodiment,, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
