10 kv overhead line branch presetting device

Abstract

The invention discloses a 10 kV overhead line branch presetting device, which comprises an insulation box and an insulation box driving device, wherein the insulation box is formed by an upper box body and a lower box body; the upper box body and the lower box body are in sliding connection through a connection device; the upper box body is provided with a power cable wire incoming end; the upperbox body is internally provided with static contacts; the static contacts are connected with the power cable wire incoming end through a static contact connection conductive component; the lower box body is provided with a power cable wire outgoing end; the lower box body is internally provided with moving contacts matched with the static contacts; the moving contacts are connected with the powercable wire outgoing end through a moving contact connection conductive component; and the insulation box driving device drives the lower box body to move relatively to the upper box body through the connection device. The requirements of operation without power failure of the modern power distribution network can be met, large area power failure and long time power failure caused by a single operation can be avoided, the personal safety of a worker can also be ensured, wire connection and power transmission are safe and reliable, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the field of power transmission, in particular to a 10kV overhead line branch preset device. Background technique [0002] In recent years, the scale of power grid construction and investment have been continuously increased. Due to the geographical location of the channel or in order to avoid the problem of occupying a large area of ​​the channel, most 10kV overhead lines adopt double-circuit or multi-circuit methods. With the development of the industrial and agricultural economy and the improvement of people's living standards, the construction tasks of branch line power supply on the established main line are gradually increasing. When it is necessary to stop fire and connect power, all double-circuit or multi-circuit lines must be cut off. , power supply companies not only need to plan and announce the outage in advance, but also need to notify the main electricity customers 7 days in advance, and prepare for the outage op...

With the development of the industrial and agricultural economy and the improvement of people's living standards, the construction tasks of branch line power supply on the established main line are gradually increasing. When it is necessary to stop fire and connect power, all double-circuit or multi-circuit lines must be cut off. , the power supply enterprises not only need to make a power outage plan in advance and make an announcement, but also need to notify the main electricity customers 7 days in advance, and make preparations for power outage operations and related safety measures. user complaint

[0003] Although the power supply department has carried out live work, no matter what kind of operation method is used, it involves the consideration of various safety distances. Due to the restriction of double-circuit or multi-circuit lines by the work site, some work parts cannot meet the safety distance requirements. Live work cannot be carried out, which affects the progress of the project and the power consumption of users
