Abstract

The utility model relates to a special insulative operating rod for high-voltage drop fuse for an electronic system, comprising a rod body. The special insulative operating rod for high-voltage drop fuse is characterized in that the top of the rod body is provided with a clip which is composed of a bottom board, a hooked head and clip heads; a U'-shaped clip mouth is formed by the two clip heads, symmetrical grooves are arranged on the two clip heads, and the distance between the two grooves is regulated by screws; a guiding hole for an insulative rope is arranged on an insulative rod, and a coak for fixing the insulative rope is arranged at the lower part of the insulative rod. The clip can prevent the head of the fusion tube from sliding off an operating rod when the tail of the fusion tube is upwardly tilted, and can prevent the fusion tube from dropping from a higher place. Compared with the prior structure like the Chinese character of 'ding', the special insulative operating rod for high-voltage drop fuse can be operated and used simply, safely and conveniently by one person, being applicable for fuse of various structures.

Description

High pressure drop out fuse special isolation action bars

Technical field

The utility model belongs to the electric power system special equipment, specifically is a kind of high pressure drop out fuse special isolation action bars.

Background technology

The high pressure drop out fuse is one of electric power system capital equipment, be widely used in distribution line, the 10KV of transformer station or the used change of 35KV and bus and press the change high-pressure side, make transformer and bus and press the fast automatic isolation that becomes the road fault again, be in operation fuse if fuse failure in the fusion tube takes place, fusion tube falls, and operating personnel keep in repair and adopt the special isolation action bars to rush to repair.The high pressure drop out fuse insulating bar that uses all adopts " fourth " glyph construction at present, utilize T-shaped crosspiece to choose to collude a crescent iron plate of fusion tube head end, one horizontal crosspiece of fusion tube head end portion is pushed in the base draw-in groove, because insulating bar is longer, and the fuse base position is higher, fusion tube is again owing to deadweight is in plumbness, less by the horizontal force that action bars applies, force operating personnel just can make fusion tube tail end about 20～30 ° of angles that raise up, otherwise the horizontal crosspiece of fusion tube head end can not slip into draw-in groove with great thrust.Because operation easier is big, generally need two people to cooperate just and can finish this operation, and fusion tube easily falls in operation, very easily damages fusion tube, and injures operating personnel, inadequately safety.

Summary of the invention:

The purpose of this utility model is at the deficiencies in the prior art, and a kind of simple in structure, easy to operate, safe high pressure drop out fuse special isolation action bars is provided.

The technical solution of the utility model is as follows:

A kind of high pressure drop out fuse special isolation action bars, comprise the body of rod, it is characterized in that: one clip is arranged at the top of the body of rod, clip is made of base plate, eave tile, dop, two dops constitute " U " shape bayonet socket, have two grooves of symmetry on two dops, and dop is fixed on the base plate by screw, the spacing of two grooves is regulated by the screw of base plate, and eave tile is welded on the outside of dop.

The top of the utility model insulating bar installs a snap ring additional, and an insulation rope bullport is arranged on the snap ring, establishes an insulation rope latching in the bottom, with the fixed insulation rope, and adjustable, insulating rope length, operating personnel are the lifting fusion tube tail end angle that raises up easily, can prevent from again that fusion tube from falling to cause damage.

The utility model is seated in the latch notch groove by the horizontal crosspiece with fusion tube head end portion, has guaranteed that action bars raises up can not fall because of fusion tube rocks to cause in the process, also can not cause fusion tube from the landing of action bars dop because of ejection firmly.The utility model is simple in structure, more convenient operation, and general single can finishing, and also safe and reliable, dop is apart from scalable, and highly versatile is applicable to the fuse of multiple structure.

The drawing explanation:

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model clip enlarged drawing.

Fig. 3 is a clip base arrangement schematic diagram.

Embodiment:

As shown in Figure 1, the utility model comprises the body of rod (1), it is characterized in that: a clip (2) is arranged at the top of the body of rod (1), as Fig. 2, clip (2) is made of base plate (3), eave tile (4), dop (5), and two dops (5) constitute " U " shape bayonet socket, the groove (6) that has symmetry on two dops, dop (5) is fixed on the base plate (3) by screw (7), and the spacing of two grooves is regulated by the screw (7) of base plate (3), and eave tile (4) is welded on the outside of dop (5).

The utility model changes former " fourth " font action bars into " U " shape bayonet arrangement of band groove, bayonet socket outside welding one eave tile, be used to collude the hook ring of choosing the fusion tube afterbody, the contact of fusion tube is chosen into fuse base plate upper end bayonet socket, two grooves of dop are placed the horizontal crosspiece of fusion tube head end portion, guaranteed that action bars raises up and can not fall in the process because of molten device rocks to cause, and when guaranteeing that horizontal crosspiece with the fusion tube head end pushes molten device base groove, reason does not push hard the top and causes fusion tube from the landing of action bars dop.

As shown in Figure 3, two screws (8) are arranged on the base plate of the present utility model, be used to regulate the dop spacing, make it to be applicable to the fuse of various structures.

As shown in Figure 1, the top of the utility model insulating bar installs a snap ring (9) additional, one insulation rope bullport (10) is arranged on the snap ring (9), establish an insulation rope latching (11) in the grip, bottom, with the fixed insulation rope, during operation, rope one end that will insulate earlier passes fusion tube tail end handle hole, pass this bullport then, insulation rope two ends are wrapped on the latching (11) at last, by regulating insulation rope slackness, the operator is the lifting fusion tube tail end angle that raises up easily, and bullport (10) is apart from action bars top length and fusion tube equal in length.

Claims
