Abstract
The utility model discloses an earthing line clamp, relating to the design and manufacture technology of transformers in power distribution project and the earthing device when line with low voltage works with power-cut. The utility model comprises a conductor and an external insulating guard housing, wherein an earthing hanging ring and a wire pin are fixed by bolts into a whole to form the conductor; the external insulating guard housing comprises a fixed guard housing and a movable guard housing. A hole for passing through wires is arranged on the fixed guard housing. The fixed guard housing is connected with the movable guard housing by a rotating shaft and a locking clipper. A combining pull ring and a hole for earthing line are arranged on the movable guard housing. The utility model is safe and reliable, because the parts of the utility model connecting with wires is fixed by the wire pin bolts, and consequently the utility model is closely contacted with the wires, thus guides large current, and has small contacting resistance, and makes full use of the earthing line, and ensures the safety of workers. Because the external insulating guard housing is high in strength, and is well anti-aging, and shields the earthing points completely in insulating mode. The utility model has good adaptability, is convenient in installation and use, and ensures no deformation of wires with small section, in particular to tiny bus.
Description
(1) technical field:
Hanging earthing conductor was used when the utility model related to transformer platform and low-voltage circuit power failure operation in the distribution engineering Design of device and manufacturing technology.
(2) background technology:
When existing transformer platform and low-voltage circuit power failure operation, hanging earthing conductor is generally adopted little bus, and earth connection is twined in the insulating barrier strip off in the low-voltage circuit, and its shortcoming is: lead is had damage, lead difference in flow, contact resistance is big.Lead is exposed after the operation, and insulation effect is bad, troublesome poeration.
(3) summary of the invention:
The purpose of this utility model is: what very the problem that solves transformer platform and low-voltage circuit hanging earthing conductor difficulty is provided is a kind of safe and reliable, the earth connection wire clamp of being convenient to operate.
The technical solution of the utility model is: be made up of conductor and external insulation guard shield, conductor is that ground connection link and lead press the angle by the bolt one, and conductor is outward the external insulation guard shield.The external insulation guard shield is made up of secure shroud and movable shield, and the lead perforation is arranged on the secure shroud, and secure shroud is connected with snap close by rotating shaft with movable shield, closes draw ring and ground wire hole on movable shield.
Of the present utility model producing effect is: have security reliability, this wire clamp adopts lead to press corner bolt to fix with the wire interconnecting piece position, contacts with lead closely, the water conservancy diversion amount is big, contact resistance is little, can give full play to the effectiveness of ground wire, has ensured staff's personal safety effectively.External insulation guard shield intensity, high anti-aging is good, and it is withstand voltage to reach more than the 30KV, and the whole insulation of hanging ground-wire point are covered, and has satisfied the insulating requirements of transformer platform and low-voltage insulation circuit, and anti-aging reached more than 10 years.Has the higher adaptability energy, because the spacing of little bus of transformer platform and low-voltage insulation line is little, sectional area of wire is little, so to the hanging earthing conductor matching requirements than higher, this wire clamp volume is little, in light weight, insulation degree height, effectively satisfy the each side requirement, can guarantee small sectional area conductor, particularly little bus is indeformable.Easy to install.
(4) description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model working state schematic representation.
(5) embodiment:
The earth connection wire clamp is made up of conductor and external insulation guard shield as shown in Figure 1 and Figure 2, and conductor is that ground connection link 1 and lead press angle 2 to be fixed as one by bolt 3, and conductor is outward the external insulation guard shield.The external insulation guard shield is made up of secure shroud 4 and movable shield 5, and the lead perforation is arranged on the secure shroud, and secure shroud is connected with snap close 7 by rotating shaft 6 with movable shield, closes draw ring 8 and ground wire hole 9 on movable shield.Conductor is made by aluminum alloy materials, and the external insulation guard shield is made for poly-third material, guard shield thickness 1.5mm, and the wire clamp total weight is 0.45kg.With lead or little bus stripping of insulatin layer, ground connection link and lead press the angle by being bolted on the lead, put the external insulation guard shield during installation.Opening the movable shield hanging earthing conductor during use gets final product.
Claims (2)
