Abstract
The utility model discloses a multifunctional grounding connection wire clamp, which comprises an upper clamping arm, a lower clamping arm, and a clamping element which is disposed between the upper clamping arm and the lower clamping arm. An end part of the upper clamping arm is provided with a bolt. The bolt is extended outwardly and is provided with a clamping nut. The utility model provides a multifunctional grounding connection wire clamp which is used in a substation. The multifunctional grounding connection wire clamp is characterized by a capability of adapting to connections of a variety of profile grounding bodies and simple structure.
Description
Technical field
The utility model relates to a kind of multifunctional grounded connecting clamp, relates to electric power system.
Background technology
Use large-scale facility at electric substation's operation field, the facility shell is wanted temporary grounding, also has not interruption maintenance need of work inicdental bypath ground connection and prevent faradic working earthing of part, present employed earth connection connector adopts crocodile clip mostly, because the earth point shape material difference of service position of living in, as: anti-error Earth pile-head with lock, ground connection channel-section steel, ground connection angle steel, ground connection band iron and ground connection round steel, cause that the plant temporary grounding is lack of standardization, ground connection is insecure and situation such as contact-making surface is not enough, mainly contain:
When 1, crocodile clip is clipped on ground connection channel-section steel, ground connection angle steel, ground connection band iron and the ground connection round steel, the one, the ground connection contact-making surface does not reach requirement, and the 2nd, ground connection is insecure, comes off easily;
When 2, running into special-purpose anti-error shape Earth pile-head, the earth connection crocodile clip can't clip Earth pile-head, earth connection can only be wrapped on the Earth pile-head, causes ground connection lack of standardization.
Summary of the invention
Technical problem to be solved in the utility model just provides a kind of multifunctional grounded connecting clamp of effective connection that can adapt to various section bar earth electrodes.
For solving the problems of the technologies described above, the utility model adopts following technical scheme, a kind of multifunctional grounded connecting clamp, comprise clamping limb, following clamping limb and be located at the described clamping element of going up between clamping limb and the following clamping limb, the described clamping limb end of going up is provided with outward extending bolt, and described bolt is provided with binding nut.
Preferably, be connected with screw rod on the described clamping element, described screw rod is located on the described clamping limb down, also is provided with the insulating bar joint on the described screw rod.
Preferably, the described clamping face specification that goes up clamping limb is 25*50mm.
Preferably, the clamping face specification of described clamping element is 25*50mm.
A kind of multifunctional grounded connecting clamp of the utility model, simple in structure, by being provided with the governor motion of regulating distance between the described clamping limb between the described clamping limb, aperture between the described clamping limb is adjustable, described earth connection is used in the ground connection maintenance and repair process of different equipment, and does not need to carry different earth connections, save manpower, having solved distinct device needs the special different earth connection of making, and saves raw material.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a kind of multifunctional grounded connecting clamp front view of the utility model;
Fig. 2 is a kind of multifunctional grounded connecting clamp vertical view of the utility model.
Embodiment
Extremely shown in Figure 2 as Fig. 1, be a kind of multifunctional grounded connecting clamp of the utility model, comprise clamping limb 1, following clamping limb 2 and be located at the described clamping element of going up between clamping limb 1 and the following clamping limb 23, described clamping limb 1 end of going up is provided with outward extending bolt 4, and described bolt 4 is provided with binding nut 5.
Described earth clip is copper, and tensile strength is not less than 207MPa, and yield strength is not less than 90MPa, and percentage elongation is not less than 6%.
The described clamping face specification that goes up clamping limb 1 is 25*50mm, and described upward clamping limb 1 and the described thickness of clamping limb 2 down are 5mm.The clamping face specification of described clamping element 3 is 25*50mm, and the clamping face area is bigger, and contact area is big in the time of can making clamping, and ground connection is reliable.Last clamping limb and described distance between the clamping limb down are 35mm, and the range of described clamping element is 30mm.The diameter of described bolt is 18mm, and length is 80mm.
Be connected with screw rod 6 on the described clamping element, described screw rod 6 is located on the described clamping limb down, also is provided with insulating bar joint 7 on the described screw rod.By rotating described screw rod 6, described clamping element 3 clamping limb 1 and described mobile between the clamping limb 2 down on described plays clamping action.
During the ordinary maintenance service equipment, when running into Earth pile-head, adopt described bolt 4 to wear the connecting hole that loads into ground connection, then fix with described binding nut, connect reliably, can accident not come off, the ground connection effect is better.Adopt when running into ground connection channel-section steel, ground connection angle steel, ground connection band iron and ground connection round steel and describedly go up clamping limb 1 and described clamping element 3 clamps, ground connection is reliable.
