A device and method for quickly replacing feeder terminals with power on

Abstract

The invention discloses an apparatus for fast lively replacing a feeder terminal. The apparatus comprises a connector socket, a connector plug and an installation tool; the connector socket is arranged on a switch body; the connector plug is arranged at the upper end of the feeder terminal; the connector plug includes a plug locking seat and a guiding shaft sleeve which sleeves the plug locking seat; the connector plug is connected with the connector socket through the plug locking seat; the plug locking seat is oppositely provided with installation cantilevers; the guiding shaft sleeve is oppositely provided with unlocking pull rods; and the installation tool includes an insulating operating rod and an installation protection basket connected with the upper end of the insulated operating rod, wherein the installation protection basket is provided with a straight rod for assembly and a bent rod for disassembly. The apparatus and method for fast lively replacing the feeder terminal of the invention are used for non-power-outage operation in the maintenance and upgrade of the feeder terminal of a distribution network, one person can replace the feeder terminal easily, and the non-power-outage maintenance of the distribution network can be realized.

Description

technical field [0001] The invention relates to the field of distribution network feeder terminals, in particular to a device and method for quickly replacing a feeder terminal with power on. Background technique [0002] The society has put forward higher requirements for power supply reliability and power outage time. In order to continuously improve the power supply reliability of distribution network, strengthen the safety management of distribution network, and comprehensively carry out condition maintenance of distribution network equipment. Overhaul and upgrade distribution network feeder terminals to achieve non-power-off operations, and continuously improve the safe and reliable operation of the distribution network. [0003] The switch is used in conjunction with the feeder terminal as the key terminal equipment of the smart distribution network. The connection method between the switch body and the feeder terminal is currently mainly connected by a control cable,...

AI Technical Summary

Problems solved by technology

However, the current connection method between the switch body and the feeder terminal and the two commonly used methods of upgrading or replacing the feeder terminal all have deficiencies. Among them, the method of connecting the switch body with the feeder terminal has the following deficiencies: 1. It is impossible to install and remove the feeder terminal under the pole without power failure; 2. The length of the connecting cable is long, and it needs to be installed and fixed on site, which is inconvenient to operate; 3. Connectors need to be installed at both ends of the control cable, which will increase the cost and affect the promotion of the product

Using the method of planned power outages, there are problems such as power outages and lowering the reliability of power supply; using the live working method of insulating bucket arm trucks, there are the following disadvantages: 1. The operation is complex and the field operation is intensive; 2. Operating cost High operating cost; 3. The surroundings are always in a live environment during operation, the work efficiency is limited, and there is a certain risk

The above-mentioned technology cannot simply realize the installation / removal of the feeder terminal under the pole without power failure, and upgrade the feeder terminal, and the feeder terminal needs to be installed on site, and the control cable and fixed cable connected to the switch body cannot fully carry out the maintenance of the distribution network equipment without power failure, which affects the reliability of power supply
