Abstract
The invention discloses a pair of fully-insulated pliers for low-voltage meter installation and electric connection operation and relates to the technical field of power facility maintenance tools. The fully-insulated pliers for low-voltage meter installation and electric connection operation comprise a first insulated plier arm and a second insulated plier arm. A threaded hole is formed in the first insulated plier arm. The first insulated plier arm is hinged to the second insulated plier arm. The first insulated plier arm and the second insulated plier arm respectively comprise a plier nose and a plier handle. The inner contact surface of each plier nose is smooth. The first insulated plier arm and the second insulated plier arm are made of polyformaldehyde materials. The fully-insulated pliers for low-voltage meter installation and electric connection operation have the beneficial effects that electricity meter and switch conducting wires can be disassembled and assembled on hot lines and the short-circuit phenomenon due to the plier body which touches the lines is avoided when the fully-insulated pliers for low-voltage meter installation and electric connection operation are used; and the working efficiency is high, the structure is simple, the manufacturing cost is low and operating personnel can be protected from being injured.
Description
Technical field
The present invention relates to electric power facility maintenance tool technical field.
Background technology
At present, in the electric power facility maintenance process, when dismounting ammeter table tail wire or switch wire, need to use flat nose pliers to operate, because the jaw of existing flat nose pliers is metal material, so in case misoperation, will bump alternate wire by mistake, cause phase fault, damage for the person and equipment.
Keep in repair this work for electric power facility at present, also do not have a kind of effective flat nose pliers, can realize charged direct dismounting ammeter table buttock line or switch wire, can not cause alternate wire short circuit.
Summary of the invention
For defective and the deficiency of prior art, the technical problem to be solved in the present invention provides and a kind ofly low press-fit table and connect electric operation all insulation pincers, can charged dismounting ammeter and switch wire; and can not cause phase fault; the protection operating personnel do not come to harm, and are simple in structure, improved operating efficiency.
Technical scheme of the present invention is: hang down to press-fit and show to connect electric operation all insulation pincers, it comprises the first insulation tong arm, the second insulation tong arm; The first insulation tong arm and the second insulation tong arm are hinged; The first insulation tong arm and the second insulation tong arm all comprise jaw, clamp handle; Contact-making surface smooth surface in the jaw; Described the first insulation tong arm and the second insulation tong arm are the polyformaldehyde material.
As preferred version of the present invention: lowly press-fit table and connect electric operation all insulation pincers, described the first insulation tong arm 1 and second tong arm inside of insulating includes the steel reinforcement; The steel reinforcement extends to the rear portion of clamp handle from the bottom of clamp handle.
As this practical preferred version: lowly press-fit table and connect electric operation all insulation pincers, the insulate hinged place of tong arm of described the first insulation tong arm and second scribbles insulating barrier, and the insulating barrier material is boron nitride.
The beneficial effect that the present invention produces is to use lowly to press-fit table and connect electric operation all insulation pincers, can charged dismounting ammeter and switch wire, and whole caliper is in all insulation state, can not cause the short circuit phenomenon that causes because of caliper touching circuit.High efficiency, and low press-fit table and connect electric operation all insulation pincers and made by the polyformaldehyde material, simple in structure, low cost of manufacture is convenient for carrying, and can protect operating personnel not come to harm.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the profile of the present invention's the first insulated pliers wall.
Among the figure, 1 first insulation tong arm, 2 second insulation tong arms, 12 jaws, 13 clamp handles, 121 interior contact-making surfaces, 14 steel reinforcements, 3 insulating barriers.
The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Embodiment 1:
Low shown in Fig. 1 embodiment press-fits table and connects electric operation all insulation pincers, comprises the first insulation tong arm 1, the second insulation tong arm 2; The first insulation tong arm 1 and the second insulation tong arm 2 are hinged; The first insulation tong arm 1 and the second insulation tong arm 2 all comprise jaw 12, clamp handle 13; Jaw 12 interior contact-making surface smooth surfaces; Described the first insulation tong arm 1 and the second insulation tong arm 2 are the polyformaldehyde material.
Further explain present embodiment, the present invention is different from the steel caliper of existing vice and the structure of rubber-covered overcoat combination, adopting the beneficial effect of polyformaldehyde material is that caliper itself is lighter, can direct charged dismounting ammeter table tail wire or switch wire during use, and do not cause phase fault.And the polyformaldehyde material also has, and intensity height, wear-resisting, toughness are strong, fatigue durability and creep resistance, have good electrical insulating property, solvent resistance and machinability.Jaw 12 interior contact-making surface 121 ganoid reasons are that shiny surface wearability ratio is strong with the surface wearability of anti-slip veins, have so just guaranteed the service life of jaw 12.
Embodiment 2:
Shown in Figure 2, to hang down to press-fit and show to connect electric operation all insulation pincers, the first insulation tong arm 1 and the second insulation tong arm 2 inside include steel reinforcement 14; Steel reinforcement 14 extends to the rear portion of clamp handle 13 from the bottom of clamp handle 13.The beneficial effect that produces like this is to be included in two insulated pliers pars intramuralis at steel reinforcement 14, further strengthen the intensity of clamp handle 13, and also reinforced the junction between clamp handle 13 and the jaw 1, so that low press-fit table to connect the intensity that electric operation all insulation pincers bear larger.
Embodiment 3:
Shown in Figure 1, to hang down to press-fit and show to connect electric operation all insulation pincers, the first insulation tong arm 1 and the second insulation tong arm 2 hinged places scribble insulating barrier 3, and insulating barrier 3 is the boron nitride material.
Further explain present embodiment: because the first insulation tong arm 1 and second insulate tong arm 2 by bolted splice, bolt is metal material, has electric conductivity.In order to guarantee low press-fit table and connect the whole state that is in all insulation of electric operation all insulation pincers, more effectively prevent phase fault, so all coat the insulating barrier 3 that material is boron nitride at the two ends of bolt.
