Background

In recent years, with the continuous development of urban distribution network equipment, the social electricity consumption is increased year by year, the contradiction between power failure maintenance, high-quality service and power supply reliability is obvious, the power failure operation time is shortened by adding the requirement of the defect elimination work such as distribution network construction maintenance and user access of national network companies, and the distribution network uninterrupted operation is normally pushed. At present, the requirements of various social circles on the safety and stability of the power industry are continuously improved, and the technological content of products related to live working is also increasingly improved. Besides strengthening strict operation training of live working personnel, the live working insulating tool is efficiently operated to be the working gravity center of uninterrupted operation of each distribution network.

Aiming at the installation of a bypass cable for distribution network uninterrupted operation, in order to improve the power supply reliability and operation safety, an insulating glove method is conventionally used, a bypass cable head is installed, the operation procedure is complex and tedious, a large amount of shielding blankets are needed, and unsafe phenomena are easy to occur in the operation process. When the insulation shielding is assembled and disassembled, the physical force of an operator can be consumed in a large amount due to long time consumption, the unsafe phenomenon easily occurs in the operation process, particularly when the exposed part of the three-phase cable head is shielded, the problem that the safety distance between the face of the operator and a charged body is insufficient occurs, and when the bypass cable head is installed, the operator needs to directly contact the charged body, if a switch is not locked to trip, electric arcs are generated when the switch is connected and disconnected, and the safety problems such as injury to the human body are caused. The life safety of operators and maintenance without power outage is seriously threatened.

SUMMERY OF THE UTILITY MODEL

The utility model provides a join in marriage bypass cable installation fastener that net work was not cut off power supply, the effectual problem of having solved that current bypass cable head installation intensity of labour is big and the security performance is low, this device sets up the fastener through adopting on the hedgehog hydnum hook physique, provides a simple and practical fastener instrument for distribution lines work of not cutting off power supply, saves high altitude live working personnel's operating time, can improve live maintainer's work efficiency again.

In order to achieve the above object, the utility model discloses a technical scheme specifically as follows:

the utility model provides a join in marriage bypass cable installation fastener that net uninterrupted power operation used, includes monkey head hook type body 1 to and install tongue plate 2 and fastening screw 3's combination on monkey head hook type body 1, through monkey head

hook type body

1 and 2 joint wires of tongue plate, its characterized in that: the end of the monkey head hook body 1 is fixed with a wire clamp 5, and the end of the bypass cable is fixed through the combination of the wire clamp 5 and the fixing screw rod 4.

The tongue plate 2 is provided with a sliding groove, and the sliding groove is meshed with a clamping groove at the end of the fastening screw rod 3, so that the tongue plate 2 and the fastening screw rod 3 can move relatively.

The wire clamp 5 and the end of the monkey head hook body 1 are arranged at an obtuse angle.

The cable clamp 5 is provided with a cable hole, the end of the bypass cable is inserted into the cable hole, and the end of the bypass cable is fixed through the fixing screw rod 4.

The utility model has the advantages that: the device provides a simple and practical wire clamp tool for distribution line uninterrupted power operation, and particularly saves the working time of high-altitude live working personnel when an insulating bucket arm vehicle insulating glove operation method and an insulating operating rod operation method are used for taking and detaching a bypass cable head in distribution network uninterrupted power maintenance operation, and the working efficiency of the live working personnel can be improved. The problem of current distribution network uninterrupted bypass cable's installation technique operating procedure complicacy loaded down with trivial details, operating personnel and electrified body safe distance not enough is solved, when the bypass cable head was demolishd in the installation moreover, the operating personnel needed the electrified body of direct contact, if the switch does not block and the tripping operation, will produce electric arc when the overlap joint is demolishd, forms safety problems such as injury to the human body. The rejection rate of the insulating shielding blanket is reduced, and live working personnel can be used by skilled operation. The tool has high strength, light weight and firm fixation of the connecting part, and the safety performance meets the condition of live working.
