Embodiment

[0032] A pre-installed quick access device for a non-power-off bypass line in a distribution network, such as figure 1 and figure 2 , including an insulating shell, the insulating shell includes an upper pressure block 1, a lower pressure block 2 movably arranged on the upper pressure block 1, a torque nut 5 is fixed on the lower pressure block 2, and the upper pressure block A locking mechanism 3 is movably provided between 1 and the lower pressing block 2 .

[0033] The insulating shell is used with strong anti-aging and flame retardancy, and the upper pressing block 1 and the lower pressing block 2 form a self-sealing insulating shell, which further enhances its pressure resistance, heat resistance and impact resistance.

[0034] Using torque nut 5 to fasten the wire clip, it is not easy to loosen, the nut is easy to operate, the fastening strength meets the requirements, and the wire is not damaged.

[0035] The upper pressing block 1 is provided with a chute 7 , the lo...

Abstract

The invention relates to a pre-installed quick access device for a non-power-off bypass line of a distribution network, belonging to the field of electric power maintenance. A torque nut is fixed on the lower pressing block, a locking mechanism is movably provided between the upper pressing block and the lower pressing block, and the locking mechanism includes a connecting head, a connecting seat and a connecting screw. The head is provided with a locking mechanism for locking the connecting screw. The advantages of the invention: the double safety structure of the locking mechanism and the locking mechanism is provided, which greatly improves the safety performance in use; the locking mechanism adopts the locking method to lock, the anti-fall effect is good, and the assembly is fast; the locking mechanism adopts the spring tongue type locking The structure is not easy to loosen, and the locking and unlocking are convenient and quick, which reduces the labor intensity of the operators, increases the operation safety, and greatly improves the access efficiency of the bypass device or the temporary power supply in the uninterrupted operation of the distribution network.

Description

technical field [0001] The invention relates to the field of electric power maintenance, in particular to a pre-installed quick access device for a bypass line without power failure in a distribution network. Background technique [0002] With the continuous development of the economy and the higher and higher requirements of users on the quality of power supply, the uninterrupted maintenance of distribution lines is becoming more and more normal. In the case of non-power outage operations, temporary equipment needs to be connected to the mains in projects with load (replacement switch with load, replacement of knife switch with load, replacement of drop fuse with load), bypass operation, and temporary power supply operation. The operation method of the prior art is to peel the main wire and then use the lapped mode of the trench wire clip to connect to the main wire. This access method requires a long operation time during the operation process and requires very high physic...
