Description
Technical Field
The invention relates to the technical field of maintenance tools of high-voltage cable distribution cabinets, in particular to a cable terminal grounding wire.
Background
In the old-fashioned junction box of 10kV salvagees the operation, in order to guarantee operation personnel's personal safety, according to the technical measure requirement, "have a power failure, test the electricity, ground connection, hang the signboard and install and block, wherein install the earth connection and be the essential important step and measure of assurance operation personnel personal safety, according to on-the-spot investigation and data statistics, old-fashioned junction box is tested and is articulated the earth connection link occupation time many, influences the salvage progress.
Disclosure of Invention
The invention provides a cable terminal grounding wire aiming at the problems, which has the following structure: the middle part of ground wire contact plate (2) is provided with the through-hole, it has cavity contact (1) to wear to overlap in the through-hole, the inside of cavity contact (1) is provided with the internal thread, its one end and screw (12) threaded connection, sleeve (11) have still been cup jointed to the outside of cavity contact (1), sleeve (11) one end and the external screw thread connection who sets up on arch (13) of ground wire contact plate (2), the one end middle part of insulator spindle (4) is provided with interior bayonet socket (3), interior bayonet socket (3) cooperate with screw (12) of cavity contact (1), the bottom of ground wire contact plate (2) is provided with nut (5), nut (5) are connected with ground wire clamp (7) through earth conductor (6).
The screw (12) is a hexagonal head screw, and the inner bayonet (3) is also a hexagonal bayonet.
An inner bayonet (3) is arranged in the middle of one end of the insulating rod (4), the other end of the insulating rod (4) is sleeved in the sleeve (10), the end portion of the sleeve (10) is perpendicularly connected with the handle (9), a through long groove is formed in the sleeve (10), at least two threaded holes are formed in the insulating rod (4), and the butterfly nut (8) penetrates through the long groove to be connected with the threaded holes to fix the sleeve (10) and the insulating rod (4) together.
The insulating rod (4) is made of insulating materials.
The using method of the invention comprises the following steps: the plug in the high-voltage branch cabinet is detached by the insulating rod (4), the wire clamp (7) is connected with the grounding clamp, the hollow contact (1) is installed at the position of the plug in front, short circuit is completed, maintenance operators start working, the hollow contact (1) is detached after the work is completed, and the plug is installed.
The invention has the beneficial effects that: when the novel device is used in actual work, the grounding wire of the cable terminal and the cable terminal can be quickly, safely and reliably grounded, and the power failure time of about 1.33h is at least shortened. The power cut amount is reduced by 18937.5kWh according to the average load of one line being 15.15MW, and the power fee income is increased by 18937.5 x 0.6771=12822.58 yuan according to the average price of power sale being 0.6771 yuan/kWh.
Labor cost: when the traditional old-fashioned junction box is tested to hang and remove test wiring, all branches with possible incoming calls need to be tested to hang, and the new device only needs to test and hang the ground wire on the elbow-shaped head of the cable terminal in the junction box in the operation process, so that the labor cost is reduced.
Safety benefits are as follows: the novel equipment is simple to operate, the technical key is easier to master, and due to the fact that the copper material is high in hardness and good in conductivity, the rear-section insulating rod guarantees personal safety.
The equipment is safe: when the grounding wire of the cable terminal is tested and hung, the threaded connection is tight, no sliding phenomenon exists after stress, enough mechanical strength is ensured, large short-circuit current cannot be loosened when passing through the cable terminal, and the cable terminal is safe and reliable.
And (4) safety of a power grid: the cable terminal grounding wire can change the original hanging test mode of large-area power failure for hanging the grounding wire in special occasions, thereby avoiding the occurrence of large-area power failure accidents, ensuring the power supply reliability and creating intangible safety benefits for enterprises and society.
