Abstract
A distribution transformer network high-voltage electricity test earthing clip is characterized in that the earthing clip is arranged in a 'b' shape, the upper straight plate section of the 'b'-shaped earthing clip is a fixing copper plate, a mounting hole used for fixed mount of the earthing clip is arranged on the fixing copper plate, the lower half section of the 'b'-shaped earthing clip is a suspension ring adopting aluminum material as a conductive core and a silicon rubber insulating layer as an outer surface layer, the bottom edge of the suspension ring is a suspension aluminum rod with an exposed conductive core, a copper-aluminum transitional section is arranged between the fixing copper plate and the suspension ring, and the surface layer of the copper-aluminum transitional section is a silicon rubber insulating layer. After power off of the transformer, the earthing clip is capable of performing electricity test and suspended connection of the earthing wire simply and securely.
Description
Technical field
The utility model relates to work about electric power circuit and equipment ground servicing unit, and a kind of distribution transformer platform district high voltage testing earthing clamp of more specifically saying so is suitable for after the transformer platform district has a power failure, at the ground clamp of high-pressure side electrical verification and hanging earthing conductor.
Background technology
Distribution transformer is at interruption maintenance with when safeguarding, according to relevant electric power safety operation or work standard and electric power safety work regulation, must be at high and low side electrical verification of power failure transformer and hanging earthing conductor, because after the power failure of high pressure fall insurance device, transformer high-voltage side lead-in wire is thinner, and conductor cross-section is generally at 16-35mm
2And be insulated wire, bring certain degree of difficulty for the high-pressure side hanging earthing conductor, also have certain potential safety hazard.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of distribution transformer platform district high voltage testing earthing clamp being provided, and is a kind of after transformer has a power failure, and can carry out the ground loop of electrical verification and hanging earthing conductor easy in the high-pressure side, safely.
The utility model technical solution problem adopts following technical scheme:
The design feature of the utility model distribution transformer platform district high voltage testing earthing clamp is to be " b " shape ground clamp is set, the straight plate section in top of " b " shape ground clamp is fixing copper coin, and described fixedly copper coin is provided with and is used for the hard-wired installing hole of ground clamp;
The lower semisection of described " b " shape wire clamp is for articulating ring, and described to articulate ring be to be that conductive cores, extexine are silicone rubber insulation layer with the aluminium, the described base that articulates ring be conductive cores exposed articulate aluminium bar;
At described fixedly copper coin and articulate between the ring and to be the copper-aluminium transition section, the top layer of described copper-aluminium transition section is a silicone rubber insulation layer.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model adopts copper-aluminium structure, silicon rubber insulation, and its volume is little, in light weight, simple in structure, mechanical strength is big, destroys pulling force greater than 80kg; Install simply, convenient and practical, waterproof, anti-aging, dielectric strength are big.
2, the utility model when mounted can be according to the angle over the ground of pile crown under the fall insurance device, adjust the top angle of electricity testing grounding ring, normal angled is 165 °, becomes the requirement of vertical angle over the ground to guarantee electricity testing grounding ring, helps the horizontally suspending of earth connection, good looking appearance.
Description of drawings
Fig. 1 is the utility model master TV structure schematic diagram.
Fig. 2 is the utility model side-looking structural representation.
Fig. 3 is the utility model user mode schematic diagram.
Number in the figure: 1 installing hole, 2 fixedly copper coin, 3 copper-aluminium transition sections, 4 articulates aluminium bar, 5 and articulates ring, 6 silicone rubber insulation layers, 7 fuses, 8 high pressure ground wires.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment
Referring to Fig. 1, Fig. 2, be " b " shape ground clamp is set, the straight plate section in top of " b " shape ground clamp is fixing copper coin 2, fixedly copper coin 2 is provided with and is used for the hard-wired installing hole 1 of ground clamp;
The lower semisection of " b " shape wire clamp is for articulating ring 5, and articulating ring 5 is to be that conductive cores, extexine are silicone rubber insulation layer with the aluminium, the base that articulates ring 5 be conductive cores exposed articulate aluminium bar 4;
At fixing copper coin 2 and articulate and be the copper-aluminium transition section between the ring 5, the top layer of copper-aluminium transition section is set to silicone rubber insulation layer 6 equally.
Referring to Fig. 3, during use, be connected with the high voltage drop-out type fuse cutout 7 of distribute-electricity transformer district with installing hole 1, when carrying out distribute-electricity transformer district work, can hang high pressure ground wire 8 in the position that articulates aluminium bar 4 and carry out electrical verification.
