Description
Technical field
The utility model is to belong to technical field of electric power detection, more particularly to a kind of novel grounded wire clamp.
Background technology
Ground wire is managing security tools and instruments indispensable in substation's interruption maintenance work, is related to the people of overhaul of the equipments staff
Body safety, it is particularly significant.When equipment switchs to maintenance after power failure grid switching operation, equipment component both sides or it is unilateral do not possess connect
Ground disconnecting link device, at this moment just needs to hang over primary equipment association conductor using external ground wire by manual type, using ground connection
Line is grounded and completes the state of overhaul of the equipments.Ground wire is connected earthing mode with conductor, can not only allow and device housings or once lead
The aftercurrent of body is released into ground, can also be avoided induced potential occur because sensing and influencing during power failure equipments, be coordinated isolation
Switch obvious cut-off point can allow equipment be in safety can touch state, at this moment substation's O＆M service personnel could in
The equipment of " maintenance " state carries out associated maintenance work.
Ground wire more often applies the situation for having a power failure, standing with change power failure and temporary grounding in 10kV outlets.With new edition《China
South electric network Co., Ltd electric power safety working regulation》Formally enable, the 7.4.2.5 articles of code is " in the line of gate framework
Trackside interruption maintenance, job site should install in line side and be grounded on the outside of plant stand earth point ".This regulation, which allows, to be measured greatly
The equipment such as the line voltage transformer at line interval lack grounding switch, with existing ground line configuration, need to use high-altitude operation vehicle,
People is risen to could mount with circuit same level.Meanwhile substation section region, working truck is larger into difficulty, because
This mounting ground wire difficulty is very big, causes the application of ground wire.
At present substation using ground wire be all ground connection clamping opening and operation lever straight line unicom by the way of, suitable for ground connection
Conductor is horizontal horizontal extension arrangement, but the equipment such as CVT is mostly from the direct vertical leads of terminal plate to the framework wire jumper of top,
The hanging wire difficulty of operating personnel will be increased using traditional ground wire, wire clamp mouth becomes level and buckles into mode, and ground connection is difficult to consolidate,
It is bad that contact area is grounded at the same time, seriously affects ground connection quality.How the ground connection that for equipment such as CVTs there are vertical leads is solved
Demand, is a great problem of current substation's maintenance work.
Utility model content
The utility model is the above-mentioned at least one technological deficiency of solution, there is provided a kind of novel grounded wire clamp, passes through
The shaft principle of helical gear is separated wire connecting clip and artificial rotation process bar two parts, with this formed core component-

The helical rotation of perforated thread groove drives first quarter moon clamping opening, so that first quarter moon clamping opening is clamped cable with hooking the hook end of folder, its
The groove of middle first quarter moon clamping opening make hook folder will not be rotated with the rotation of threaded rod, can only linear running, ensure clamp it is firm.
Further, connecting portion includes positioning base, shell, and shell is connected by fixing bolt with positioning base, positions bottom
Seat is equipped with two notches, the first angular wheel, the second angular wheel, promotes folder to be each passed through notch and the first taper with operation lever
Gear, the connection of the second angular wheel, the first angular wheel, the second angular wheel are corresponded in positioning base in a manner of axially vertical
It is connected.Vertically it is connected by gear and realizes vertical hanging wire, rotating operation bar, operation lever drives the second conical tooth rotation
Dynamic, the second angular wheel drives the first angular wheel to rotate, and the first angular wheel, which drives, promotes folder to rotate, and promotes folder logical with hooking folder
Cross to be threadedly coupled and the cable of hanging wire to be carried out is clamped.
Further, position-limit mechanism is equipped with limiting plate, and limiting plate is equipped with limited mouth, gasket, and one end of limiting plate passes through bolt
It is flexibly connected through gasket and limited mouth with connecting portion, the other end of limiting plate is connected by bolt and the fixed of the non-hook end for hooking folder
Connect.Gasket makes bolt be connected firmly with positioning base, when hook folder drives hook folder movement because of threaded rod rotation, when bolt is touched
During the limited mouth end of limiting plate, hook folder and will be unable to continue to move to, so as to play restriction effect.
Further, operation lever is equipped with insulation division and metal portion, and the metal portion is connected with connecting portion, and the metal portion passes through
Bolt is connected with insulation division, and the insulation division is equipped with operating handle in one end away from metal portion.The insulation division of operation lever is modeling
Material, plays the role of primary insulation, and length is longer, ensures the safety work of operating personnel.Operating handle convenient working personnel
Use rotation process bar during earthing clamp progress wiring.
Further, operating handle is equipped with retaining ring, antiskid thread.Retaining ring in order to prevent operator when carrying out operation lever rotation
Hand extends to connecting portion, so as to cause to get an electric shock.Antiskid thread is the frictional force for increasing human hand and operation lever, makes operator more square
Just rotation process bar.
The beneficial effects of the utility model are：
（1）Vertical leads are realized using the rotating manner of rotation process bar, there is provided a kind of efficient, convenient, reliable ground
Earthing clamp.
