Description
Technical field
The present invention relates to a kind of extended pattern direct current connecting terminal blocks, and it is daily to be suitable for the automation of network system transforming plant protecting
Maintenance, belongs to electric power tool field.
Background technique
For some overhauls of current 110kV, 35kV substation, technological transformation and the usually work such as defect elimination, sometimes we are needed
A plurality of power supply point is drawn in direct current system.In most cases we get used to replacing (multiple) both-end
Son row goes " pressure two-wire " to draw power supply;We just need to disconnect former operation DC power supply in this way, but require in certain work
DC power supply cannot be disconnected, this just works to us and brings difficulty.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind to carry out quickly in the case where not turning off DC power supply
The extended pattern direct current connecting terminal block of extension.
A kind of extended pattern direct current connecting terminal block including insulation crust, the long cable section of ingoing line mouth being arranged on insulation crust, passes through
Wear insulation crust long screw and insertion and do not run through insulation crust short screw;
One end of the long screw and conductive sheet is conductively connected, the precession direction of the short screw and the other end of the conductive sheet
Corresponding, waiting cable tight of the other end of the conductive sheet in the case where the precession of short screw pushes and in the long cable section of ingoing line mouth is matched
It closes and is conductively connected;
The long screw is pierced by the screw rod of insulation crust except end is externally provided with screw rod insulating protective sleeve, the long screw and short spiral shell
Nut insulation protection cylinder is cased on the nut of silk.
Further, the insulation crust is equipped with the screw thread for matching fastening with the long screw, short screw respectively.
Further, the insulation crust, nut insulation protection cylinder and screw rod insulating protective sleeve are integrally formed.
Further, the long cable section of ingoing line mouth is Phoenix formula connection jaws.
Beneficial effects of the present invention are as follows:
The present invention can not only draw new power point in the case where continuous open shop DC power supply, but also to solve " pressure two-wire " insecure
Bring security risk.The present invention firmly installs, using flexible, applied widely.
The common DC terminal row of substation all arranges using for Phoenix DC terminal, and general wiring is to draw from one end
Enter wiring, the other end draws wiring and sometimes needs to draw new power point again, but be easy to cause fortune when single extraction power supply point
Row circuit power-off, because may move former Phoenix DC terminal row while adding new lead, inevitably
The operating loop for connecing and drawing on DC terminal row can be moved, it is possible to influence former supply voltage;Or it goes to unclamp former phenanthrene
Knicks DC terminal arranges one end and " pressure two-wire " is gone to remove to draw power supply, but this wiring is while unclamping terminal block one end,
Operation supply voltage is just inevitably influenced, and " pressure two-wire " this mode of connection itself is not easy line to compress,
Phenomena such as will cause voltage instability.If former DC power supply is applied in the important protective device power supply of substation, at this time will
Influence is arrived at a station interior important protective device, it is possible to cause substation's leapfrog accident.
The present invention effectively solve the problems, such as it is above-mentioned bring, the terminal block of extension is fixed by long screw, and shell is according to Fei Nike
This groove design, effectively agrees with therewith, and shell is designed using all insulation, ensure that the safety of installation, lead-out wire is fixed on card
It in slot, is fixed with short screw, keeps wiring stronger, the present invention can be straight in Phoenix while not turning off operating loop
Stream terminal block itself extends a firm terminal block, keeps extraction supply voltage more stable.
Phoenix DC terminal row's groove itself has a thread, that is, the position tightened up a screw is for upper in itself
In flakes, it according to this thread combination reality of work, designs and goes out fixed scalability DC terminal row from groove.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is use state diagram of the invention.
Wherein, 1 long cable section of ingoing line mouth, 2-1 insulation crust, 2-2 nut insulation protection cylinder, 2-3 screw rod insulating protective sleeve, 3 are led
Electric piece, 4-1 long screw, the short screw of 4-2,5 direct current Phoenix terminal blocks, 6 fixed slots.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, 1- attached drawing 2 and specific implementation with reference to the accompanying drawing
Example carries out clear, complete description to invention.
As shown in Fig. 1-Fig. 2, the present embodiment is related to a kind of extended pattern direct current connecting terminal block, including insulation crust 2-1,
Long cable section of ingoing line mouth 1 on insulation crust 2-1 is set, through the long screw 4-1 of insulation crust 2-1 and insertion and not through exhausted
The short screw 4-2 of edge shell 2-1;
One end of the long screw 4-1 and conductive sheet 3 is conductively connected, the precession direction of the short screw 4-2 and the conductive sheet 3
The other end it is corresponding, the other end of the conductive sheet 3 is in the case where the precession of short screw 4-2 pushes and in the long cable section of ingoing line mouth 1
Cable tight fit waiting and conductive connection;
The long screw 4-1 is pierced by the screw rod of insulation crust 2-1 except end is externally provided with screw rod insulating protective sleeve 2-3, the length
Nut insulation protection cylinder 2-2 is cased on the nut of screw 4-1 and short screw 4-2, protection staff avoids danger of hazardous electrical discharges.
Further, the insulation crust 2-1 is equipped with for matching tightly with the long screw 4-1, short screw 4-2 respectively
Solid screw thread, facilitate adjusting screw precession depth, install stronger, use is more flexible, and the scope of application is wider.
Further, the insulation crust 2-1, nut insulation protection cylinder 2-2 and screw rod insulating protective sleeve 2-3 one at
Type, insulating properties is more preferable, is not easy to leak electricity.
As shown in Fig. 2, the long cable section of ingoing line mouth 1 is Phoenix formula connection jaws, it is convenient for and former direct current Phoenix terminal
Row 5 is with the use of more convenient.The common DC terminal row of substation all arranges 5 using for Phoenix DC terminal, generally
Wiring is to introduce wiring from left end, draws wiring from right end.
The course of work of the present embodiment is as follows: when installation, the cable newly accessed is first fixed on the long cable section of ingoing line mouth 1,
And conductive sheet 3 is pressed on the cable waiting in long cable section of ingoing line mouth 1 with short screw 4-2 precession, complete long screw 4-1, conduction
It is conductively connected between cable waiting in piece 3, short screw 4-2 and long cable section of ingoing line mouth 1, then utilizes fixed slot 6, insertion need to open up
In the former direct current Phoenix terminal block 5 of exhibition, and fixed using long screw 4-1.
The insulation crust 2-1, nut insulation protection cylinder 2-2 and screw rod insulating protective sleeve 2-3 are ambroin, internal
For conductive sheet 3 using aluminium or other conductive and fixed materials, terminal row's height is 3200mm, screw diameter 300mm;It is fixed to insert
Slot 6 is the square slot of 500*500mm.Terminal row can reliably connect on the basis of not turning off original DC power supply
It connects at former 5 top of direct current Phoenix terminal block, fundamentally solves the above problem.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations;Although
