Abstract
The utility model provides a 90-degree bending spanner for a lead wire of a coil. The spanner consists of a straight arm, an L-shaped arm and two fastening pieces. The straight arm and the L-shaped arm are cut by a steel plate, wherein the straight arm is straight line-shaped, and one end of the straight arm is provided with the two fastening pieces, i.e. the fastening piece which is arranged at the top end is a jointly-used fastening piece, and the fastening piece which has a certain distance from the jointly-used fastening piece is a straight arm fastening piece; the L-shaped arm is L-shaped, the bending place of the L-shaped arm is provided with an L-shaped fastening piece, one end of the L-shaped arm which is near to the L-shaped fastening piece is provided with the jointly-used fastening piece, and the straight arm is connected with the L-shaped arm by the jointly-used fastening piece, so that the L-shaped arm can omni-directionally rotate; and the straight arm and the L-shaped arm are force arms for bending the lead wire; and each fastening piece mainly consists of a screw bolt, a screw nut, an inner lining ring and an outer lining ring, the straight arm fastening piece and the L-shaped arm fastening piece can fix the position of the lead wire, the jointly-used fastening piece also can be a force applying point for bending the lead wire, the depth of the inner lining ring is slightly larger than that of the lead wire to prevent the lead wire from being directly rubbed with the bolt, and the inner lining ring can be changed to be applied to the lead wires with various specifications.
Description
Technical field
The utility model relates to the making frock of auxiliary transformer in a kind of electric locomotive, lead-in wire is lifted one's head 90 ° bending spanner when referring in particular to a kind of transformer coil winding, this kind spanner can make 90 ° of bending lift one's head that moulding is attractive in appearance, smooth, insulation is injury-free, reduces the transformer coil disqualification rate effectively.
Background technology
At present, because six-axle car 300KVA auxiliary transformer need do water test, 300KVA is auxilliary become wire insulation into polyimide film sintered, Nomex paper is wrapped, in winding process, high-voltage connection being carried out 90 ° lift one's head when bending, generally all is to adopt common wrench to bend; Lift one's head when bending but adopt common original spanner that high-voltage connection is carried out 90 °, usually damage wire insulation easily.Be only limited to fixedly bending of specification lead owing to original spanner in addition, and the elbow injustice that bends out, there is the phenomenon of twisting.Therefore need further to be improved.
Summary of the invention
The purpose of this utility model bends deficiency in the process in order to overcome existing transformer coil spanner exactly, propose a kind of simple to operate, the transformer coil lead-in wire bends device for 90 ° easily.
The technical scheme that its technical problem that solves the utility model adopts is: 90 ° of bending spanners of a kind of transformer coil lead-in wire, form by straight-arm, L type arm and securing member three parts.Described straight-arm and L type arm adopt the steel plate cutting to form, straight-arm type linearly wherein, an end has two securing members, top be shared securing member, what certain distance is arranged with shared securing member is the straight-arm securing member; L type arm is the L type, and individual L type arm securing member is arranged in the bending place of L type arm, and an end close with L type arm securing member has a shared securing member, and straight-arm is connected by shared securing member with L type arm, therefore can omnibearingly rotate; Straight-arm and L type arm are the arm of force of lead-in wire when bending; Described securing member mainly is made up of bolt, nut and inside and outside lining ring, straight-arm securing member and L type arm securing member can fixing cord the position, shared securing member also is simultaneously the stress point of lead when bending, interior lining ring thickness is a bit larger tham conductor thickness, avoid lead and bolt direct friction, more the changeable liner circle is to be suitable for and all size lead, and outer lining ring stops that lead breaks away from, overturns, twists when bending.
The utility model provides a kind of 300KVA auxiliary transformer coil lead of can finishing to bend for 90 °, and not damage wires insulation can be suitable for and 90 ° of devices that bend of other transformer coil lead-in wires simultaneously.
Description of drawings
Fig. 1 pulls structural representation in of the present utility model;
Fig. 2 is the outer structural representation of pulling of the present utility model;
Among the figure: 1. L type arm, 2. shared securing member, 3. straight-arm, 4. straight-arm securing member, 5. L type arm securing member, 6. lead.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1, shown in Figure 2 be 90 ° of bending spanners of a kind of coil lead, form by straight-arm, L type arm and securing member three parts.Described straight-arm 3 and L type arm 1 adopts the steel plate cutting to form, straight-arm 3 type linearly wherein, an end has two securing members, top be shared securing member 2, what certain distance is arranged with shared securing member 2 is straight-arm securing member 4; L type arm 1 is the L type, and individual L type arm securing member 5 is arranged in the bending place of L type arm 1, and an end close with L type arm securing member 5 has a shared securing member 2; Straight-arm 3 and L type arm 1 are the arm of force of lead-in wire when bending; Described securing member mainly is made up of bolt, nut and inside and outside lining ring, straight-arm 3 is connected by shared securing member 2 with L type arm 1, therefore can omnibearingly rotate, shared securing member 2 also is simultaneously the stress point of lead when bending, straight-arm securing member 4 and L type arm securing member 5 can fixing cord the position, lining ring thickness is a bit larger tham conductor thickness in the securing member, avoid lead and bolt direct friction, more the changeable liner circle is to be suitable for and all size lead, and outer lining ring stops that lead breaks away from, overturns, twists when bending.
According to on-the-spot actual, can select Fig. 1 in pull or the outer of Fig. 2 pulled, select the interior lining ring of suitable thickness then, by Fig. 1 or shown in Figure 2 lead is laid, regulate bending a little, with outer lining ring the lead both sides are blocked, then all nuts are screwed slightly, pulling spanner, is 90 ° with the lead bending, and then unclamps nut and take out the operation that lead descends operation.
