Description

The online erecting device of power equipment phase sequence nameplate

Technical field

The utility model belongs to power industry supply line technical field, more particularly to a kind of power equipment phase sequence nameplate Online erecting device.

Background technology

At present, there is installation phase sequence nameplate in newly-built outdoor electric facility, nameplate is usually to be arranged on cross-arm.Mark Show board after by longtime running, the phenomenon that mark obscures, aging comes off occurs in part nameplate.If to such nameplate Carry out replacing and fill a vacancy to step on bar replacing, it is necessary to have a power failure, it is cumbersome and time consuming, and line outage can influence the economy of enterprise, society Benefit.Therefore, can only be when equipment be because of other reason power failure work, in passing to mark in actual treatment nameplate replacement problem Show that board is changed.But this method can not timely and effectively carry out nameplate and change work of filling a vacancy.Therefore, it is necessary to research and develop electric power The online erecting device of equipment phase sequence nameplate.

Domestic patent database also discloses that some online erecting device technologies of power equipment phase sequence nameplate, such as：【Name Claim】Band cable address phase-sequence plate operation device【Application number】CN201320781657.7【The applying date】2013.12.03, disclose powered Phase-sequence plate operation device is hung, including the expansion link made of insulating materials, expansion link upper end are provided with fixed plate, fixed plate is provided with With the slot of expansion link diameter parallel, vertically fixed cover is provided with the middle part of expansion link, is rotatably connected to rotating shaft in fixed cover, outside rotating shaft End is vertically provided with sleeve pipe, and sleeve pipe both ends are provided with closure plate, and the pull bar that sleeve pipe is stretched out at both ends is equipped with sleeve pipe, and pull bar one end is provided with Drawstring, the pull bar other end are provided with drag hook, and pull bar is provided with the baffle plate in sleeve pipe, is provided with sleeve pipe and is through on pull bar simultaneously position Compression spring between baffle plate and one piece of closure plate；Phase-sequence plate is inserted with slot, phase-sequence plate upper end has by rivet to be cut Face is in the connecting plate of angle shape, and the horizontal segment edge of connecting plate is provided with clamp system.The utility model is specially adapted for phase Sequence board is articulated on the crossbeam of angle shape, and phase-sequence plate is mounted under powering-off state of not operating a switch, not only securely and reliably, and not shadow Ring resident and business electrical.But the utility model needs to install the connecting plate of angle shape on nameplate, and connecting Clamp system is installed on plate.It is small and thin because nameplate is usually that plastics are made, it is difficult to which connecting plate and clamp system are loaded onto Go, and cost is also higher；Need using different connecting plates for crossbeam of different shapes in addition and set clamp system, It is unfavorable for being widely applied, therefore for its online erecting device, applicability is undesirable.

The replacing or its online erecting device is poor for applicability asks it can be seen that existing equipment phase sequence nameplate presence must have a power failure Topic is, it is necessary to further improve.

The content of the invention

The purpose of this utility model is that solve shortcoming and defect existing for existing equipment phase sequence nameplate, there is provided Yi Zhongshi With property is strong, security is good, the simple operation online erecting device of power equipment phase sequence nameplate.

To achieve these goals, the utility model provides following technical scheme：

The online erecting device of power equipment phase sequence nameplate of the present utility model, it is segmented and bends using Elastic Steel strand The Double spring portion of formation and hook part, the hook part are located at elastic part end, and elastic part and hook part form and horizontal stroke together The triangle buckle that load shape matches.The elastic part is that the herringbone formed that crossed by upper elasticity arm and down spring arm combines Body.Upper elasticity arm and down spring arm share four sections of steel wires, and both form elastic force angle in junction.Elastic Steel strand is respectively in upper bullet The arm of force, the end of down spring arm are inwardly vertically bent to form fixed hook, lower fixed hook.Down spring arm is close to lower fixation Sinuous formation annulus at crotch, circle diameter are more than the operating head cross bar diameter of insulating bar.The angle at elastic force angle has no will Ask, as long as ensureing that upper minimum range between fixed hook, lower fixed hook is more than cross-arm width.The present apparatus is to utilize elasticity The resilient clamp cross-arm that steel wire bar has in itself, hook part is caught on the angle steel edge of cross-arm top, provided for nameplate outstanding Carry body.

As further explanation of the present utility model, the online erecting device of power equipment phase sequence nameplate is by stainless steel elasticity Steel wire is made, and the present apparatus is brought into close contact according to cross-arm features of shape machine-shaping, realization with cross-arm.

As further explanation of the present utility model, anti-dropping clamp is provided with the lower fixed hook side.The anti-dropping clamp By two sections mutually steel wires at a right angle form, anti-dropping clamp one end is connected crotch side, under the other end extends but is no more than to the left The extended line of straight line where elasticity arm.When in use, the operating head of insulating bar is passed through into double annulus, plays support and fix and keep The stable effect of device horizontal direction.

As further explanation of the present utility model, the lower fixed hook hangs nameplate by cord, makes nameplate The present apparatus can be followed to be fastened on cross-arm.

Compared with prior art, the beneficial effects of the utility model are：

(1) form the triangle buckle structure to match with cross-arm shape together using elastic part and hook part, this can be made Erecting device is brought into close contact cross-arm, and keeps safe distance with other charging equipments.
