Abstract
The utility model relates to a grounding wire. The grounding wire includes an insulating rod and a grounding tongue which are connected by a screw rod. The grounding tongue is fixed with a grounding head corresponding to the grounding tongue. The insulating rod includes a plurality of sections which are in extension-type connection. The grounding wire has the advantages that 1) the insulating rod is set to be a multi-section structure, and connections between the sections are adjustable, so that the length of the insulated rod can be adjusted by adjusting the connection position between the sections, meeting the requirements of a variety of environments; and 2) a mounting part of the grounding head is set to be a curved mouth for reliable contact and easy dismounting between the grounding head and a conductor, thus the conductor with a circular cross-section is blocked in the curved mouth, the contact surface is increased, and a good contact state is maintained during using.
Description
Technical field
The utility model relates to a kind of earth connection, is applied in the occasion of electric substation's low pressure maintenance.
Background technology
Guarantee the staff when unexpectedly voltage occurring on the equipment that has had a power failure and circuit, must arrange and connect wires; But in some occasions, because the substation is only 10cm with covert spacing, it is the copper rod of φ 12 that step-down used extrudes existing pile crown, and be connected to the low-voltage insulation outlet, and existing low-voltage grounding wire insulating bar is single-unit, and length is more than 40cm, and length is unadjustable, the grounding head width is more than 10cm, because the restriction of size can't be used fully.
The utility model content
The utility model is for defects, purpose be to provide a kind of simple in structure, insulating bar length can be regulated connects wires.
The technical solution adopted in the utility model is for this reason: the utility model includes insulating bar and the ground connection tongue that connects by screw mandrel, is fixedly installed the grounding head corresponding with it on the ground connection tongue, and described insulating bar is the more piece setting, is scalable connection between each joint.
Described insulating bar comprises sheathed external insulation bar and interior insulating bar, and both correspondence positions are established some bayonet sockets of arranging vertically, by fastener, both are connected.
Described fastener comprises the bayonet lock that is arranged in interior insulating bar, exist a card rod to pass bayonet lock and bayonet socket, and at the outer sheathed spring of card rod, spring one end supports and is located on bayonet lock, and the other end is to being located in interior insulation.
Arc port is arranged at the position of described grounding head clamping conductor.
The utility model has the advantages that: 1) the utility model is arranged to multi-section structure with insulating bar, and the link position between each joint is adjustable, be the length of capable of regulating insulating bar by the link position of adjusting between each joint like this, reached the instructions for use of satisfying in various environment; 2) the utility model contacts reliable, easy accessibility in order to make between grounding head and conductor, the utility model is arranged to arc port with the installation portion of grounding head, the cross section is just sticked in arc port automatically for circular conductor like this, and contact-making surface increases, and in use can remain good contact condition.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model fastener.
Fig. 3 is the end view of Fig. 1 ground connection tongue.
In figure, 1 is that insulating bar, 2 is spring for bayonet lock, 63 for card rod, 62 for bayonet socket, 61 for grounding head, 51,52 for ground connection tongue, 4 for screw mandrel, 3.
Embodiment
The utility model mainly improves former earth connection.As shown in Figure 1, the utility model earth connection comprises:
1) insulating bar 1 is telescopic, minute two joints, and material is the epoxy resin extubation tube;
2) screw mandrel 2 one ends are arranged on insulating bar 1, and the other end is by grounding head 4, and end is arranged on ground connection tongue 3.By rotating insulated bar 1, screw mandrel 2 drives ground connection tongue 3 and rises or descend, and makes grounding head 4 tighten up or loosen;
3) bayonet socket is totally 2, externally on insulating bar, is respectively bayonet socket 51 and bayonet socket 52;
4) fastener is arranged on primary insulation bar end, as shown in Figure 2, is comprised of card rod 61, bayonet lock 62, spring 63.Card rod 61 is copper rod, and bayonet lock 62 passes card rod 61, by the elastic force of spring 63, makes card rod 61 be fixed in bayonet socket 51,52.
As a specific embodiment of the present utility model, as to be applied to the substation be 10cm with covert spacing, when step-down extrusion line pile crown is the occasion of copper rod of φ 12, adopts following concrete mode:
The utility model is improved to insulating bar 1 telescopic, minute two joints, and overall length is 40cm, when guaranteeing insulating safety distances, simple operation, convenient working personnel's use improves operating efficiency.Can select between bayonet socket 51 and 52 according to job requirements, regulate the length of insulating bar 1.
Grounding head 4 sizes are improved, and grounding head 4 width are 38mm, and the design of arc port size makes that earth connection contacts with earthing device well with conductor, easy accessibility; The use almag guarantees that as the main material of grounding head 4 grounding head 4 has enough mechanical strengths and excellent electric conductivity, and unlikely loosening when large short circuit current passes through, and satisfies D.C. resistance test requirements document in groups, guarantees staff's personal safety.
