Description
Technical field
The invention belongs to power high voltage side current strap to be electrically accessed field of measuring technique, powered can be assembled and disassembled more particularly to one kind
High-tension current pincers.
Background technology
Opening or Open Type Electric Current Mutual Inductor can be installed because that need not disconnect busbar of high pressure, and reality is brought to user
It is convenient, it is widely used in recent years, in terms of the product form applied at present, mainly there are two kinds, the first is the inverted electricity of high pressure
Current transformer structure, i.e. a busbar are passed through from secondary winding, a secondary winding filling dielectric and complete electric insulation every
From secondary winding is broken away two halves, embraces and is filled on busbar so as to folding, is completed from the secondary side number of winning the confidence to primary current during measurement
Conversion, need during installation the equipment that aids in and frock more, if powered installation, it is necessary to auxiliary mould and operation sequence more
It is cumbersome, generally require the protective garment that operating personnel's wearing and adapted specialty arc protection are burnt and prevent, protect the protector such as blanket, stand powered
In Operation Van, closely holding specific purpose tool could complete to install；
The problem of second is the mode for taking high pressure equipotential to measure, and which has evaded high-low pressure insulation, security
Significantly increased than former mode, it is made of two parts, first, the opening electricity of the scissor open-and-close mechanism with closing spring
Current transformer, second, closing the crane bar together with being screwed with opening current transformer spiral shell snap fit, the product form is in powered installation
Convenience on it is also more simpler than former mode, operating personnel can stand on the ground, and hand-held crane bar alignment busbar above pushes away,
Scissor shedding mechanism is completed to fill the span of a man's arms busbar action under the action of closing spring, you can measurement is completed, it is counter to push away similarly, and during dismounting
Drop-down crane bar can be completed to dismantle；In terms of practical application, this two classes product form is primarily present the following aspects and asks at present
Topic：
1st, the first product form, the insulation of secondary winding opening is weak, and according to national standard, shelf depreciation index is difficult to close
Lattice, hidden danger is brought to safety.In addition, installation subsidiary conditions are even more cumbersome.
2nd, second of product form, has evaded Insulation Problems, for the scissor open-and-close mechanism with closing spring, is only capable of covering
On busbar, it is impossible to pressure busbar is reliably embraced, in addition, the opening electricity for the hand-held crane bar for lifting assembly and disassembly and the product form
Current transformer spiral shell snap fit synthesizes an entirety, and crane bar cannot be disassembled individually during assembly and disassembly, therefore be only used for interim measurement, no
It can be used for long-term on-line measurement.
The content of the invention
During the purpose of the invention is to overcome the current transformer dielectric level that has been open low and measure for a long time
The deficiency of card line loosely, propose it is a kind of can powered assembly and disassembly high-tension current pincers, including high-tension current pincers and high-tension current clamp
Frock is assembled and disassembled, high-tension current pincers can be firmly installed on high voltage bus by the present invention under conditions of powered, or female from high pressure
Disassembled on line.The structure of the present invention has not only evaded Insulation Problems, but also the machinery for improving outdoor longtime running is reliable
Property.
It is proposed by the present invention it is a kind of can powered assembly and disassembly high-tension current pincers and its assembly and disassembly frock, it is characterised in that including height
Current voltage pincers, high-tension current pincers assembly and disassembly frock two parts, wherein high-tension current pincers include tiltedly cuing open into the semicircle of left and right two by decile
Device body, closing spring, crimping spring bearer plate, the pressing plate of ring structure trigger support plate, assemble and disassemble spacing draw ring, the electricity such as device body is internally formed
Position opening current transformer cavity volume；Wherein, two semi-circular portions joints of device body are respectively provided with connection rotation axis, device body closure bullet
Spring is arranged on the lower part junction of two semicircular rings of device body, and connection rotation axis is fixed by pin through device body closing spring, device
Body closing spring both wings press on the periphery of two subdivision semicircles respectively, play the role of two members close of device body；Crimping
Spring bearer plate is by the fixing piece of one end in the right semi-circle ring of device body, shaft, pin, aerofoil profile bullet on fixing piece
Spring and pressing plate composition, pin is fixed through aerofoil profile spring and rotation axis, when device body is closed on the horizontal plane in cavity volume, is risen
To the effect of crimping, pressing plate triggering support plate is fixed on the other end in right semi-circle ring；Wherein high-tension current pincers assembly and disassembly frock includes drawing
Ring spring carrier arm, device body limiting slot, crane bar nut；Wherein draw ring spring carrier arm is installed for the hook of drop-down dismounting high-tension current pincers
Structure, is fixed by pin through rotation axis and aerofoil profile spring, hook and device body limiting slot upper edge hole horizontal vertical；Device body limiting slot is support
