Withstand cable guide, this mode of operation is laborious, tired, also terminal box Interface Terminal easy to damage, and has the danger of electric shock
Etc. drawbacks, also, measurement process increases artificial influence factor, will appear voltage signal if slightly shaking and trembles, and influences
Measurement accuracy reduces work effect, and will form erroneous judgement.
Summary of the invention
The utility model is to propose a kind of lightning arrester live-line test in order to avoid the problems of above-mentioned prior art
Voltage signal acquisition and transmission pincers, to be able to achieve the voltage signal automatic collection and biography of lightning arrester live-line test process
It is defeated, it is time saving and energy saving so as to improve measurement accuracy.
The utility model adopts the following technical scheme that in order to solve the technical problem
The characteristics of voltage signal acquisition and transmission pincers of a kind of lightning arrester live-line test of the utility model is that setting is a pair of
Tong arm；It is connected between the pair of tong arm by spring；The top of the pair of tong arm is equipped with clamping part；In the pair of pincers
Inside extension is provided on any side tong arm in arm；Transmission conductor is provided on the extension；Transmission conductor
Between the pair of tong arm；The top of the transmission conductor is connected with acquisition terminal；The tail end of the transmission conductor connects
There is terminal box；
The pair of tong arm is fixed on the insulation division outside terminal block under the action of the spring by the clamping part
Divide on edge, and be in contact with the acquisition terminal with the conductor crimping screw in the conductor crimping hole of terminal block, forms opposite end
Son arranges the acquisition structure of upper voltage signal；The voltage signal is passed to the terminal box, the wiring by the transmission conductor
Box matches with external plugging member；The plugging member passes through the voltage signal inputs of signal wire and arrester live detection instrument
Sub- place is connected, to form the transmission structure of voltage signal.
Compared with the prior art, the utility model has the beneficial effect that:
1, the voltage signal acquisition of the utility model and transmission pincers are in design, using plug and play as target, without disconnecting
Buckling case lead, size meet the Circularhole diameter requirement of each buckling terminal interface, improve it is existing need in test it is artificial right
Lead carries out various transformation so that the shortcomings that increasing personnel's investment, economic input, reducing working efficiency.
2, after the voltage signal acquisition of the utility model and transmission pincers size design are good, in order to take voltage stabilization, contact
Well, discharge off gap uses magnetic material at the signal acquisition terminal of voltage signal acquisition and transmission pincers, risen with flat mouth etc.
Scientific design is carried out for reference, to ensure that contact area and closeness of contact.
3, the transmission conductor of the voltage signal acquisition of the utility model and transmission pincers conductive material low using resistivity, together
When surface carry out anti-oxidant treatment, ensure that voltage signal is undistorted；In the exposed metal/bare metal portion that tong arm, user of service may touch
Position meets live use demand using reliable insulation package, insulation performance.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Figure label: 1 a pair of of tong arm, 2 springs, 3 terminal boxes, 4 acquisition terminals, 5 transmission conductors (contain external insulation layer).
Specific embodiment
In the present embodiment, as shown in Figure 1, a kind of voltage signal acquisition of lightning arrester live-line test and transmission pincers, comprising:
A pair of of tong arm 1, spring 2, terminal box 3, acquisition terminal 4, transmission conductor 5 (containing external insulation layer).
A pair of of tong arm 1 using cross-linking polyethylene materials manufacture is set；It is connected between a pair of of tong arm 1 by spring 2；One
To tong arm 1 and 2 mating reaction of spring, reach holding and fixed function.The top of a pair of of tong arm 1 is equipped with clamping part；It is adopted close
The clamping part of collection 4 side of terminal can also play holding, and tail portion adjusts tong arm opening degree for user of service.In a pair of of tong arm 1
Any side tong arm on be provided with inside extension；Transmission conductor 5 is provided on extension；Transmission conductor 5 is in one
To between tong arm 1；The top of transmission conductor 5 is connected with acquisition terminal 4；It acquires terminal 4 and uses magnetic material, with transmission conductor 5
In metal part connection, the voltage signal acquisition in terminal block on terminal is come out, is transmitted at terminal box 3.Transmission conductor 5
Tail end be connected with terminal box 3；Terminal box 3 is M8 × 58mm binding post, jack diameter 6mm, with the metal portion in transmission conductor 5
Divide connection, cooperation signal cable is transmitted to instrument input terminal for the collected voltage signal of terminal 4 is acquired.
In specific implementation, a pair of of 1 application method of tong arm: after acquisition terminal 4 collects required voltage signal, user
Member is acted on by tong arm and spring 2, and voltage signal acquisition and transmission pincers are fixed on the insulated part edge outside terminal block.
3 application method of terminal box: in the jack using 6mm stick plugging member insertion terminal box 3,6mm stick plugging member is another
One end is connect with signal wire, is led at voltage signal inputs of arrester live detection instrument.
Acquisition 4 application method of terminal: acquisition terminal 4 protrudes at the conductor crimping hole of terminal block, tight with conductor crimping screw
Contiguity touching, acquires the voltage signal in terminal block.
So that a pair of of tong arm 1 can be fixed on the insulation division outside terminal block under the action of spring 2 by clamping part
Divide on edge, and is in contact with acquiring terminal 4 with the conductor crimping screw in the conductor crimping hole of terminal block, shape paired terminals row
The acquisition structure of upper voltage signal；Voltage signal is passed to terminal box 3, terminal box 3 and external plugging member phase by transmission conductor 5
Matching；Plugging member is connected by signal wire with the sub- place of voltage signal inputs of arrester live detection instrument, to form electricity
Press the transmission structure of signal.
