On-line power distribution line monitoring acquisition terminal supporting automatic resetting

Abstract

The invention discloses an on-line power distribution line monitoring acquisition terminal supporting automatic resetting, and aims at solving the problem of inaccurate resetting time of a terminal. The on-line power distribution line monitoring acquisition terminal supporting the automatic resetting comprises a main body, wherein a power supply module, a remote control switch, a current sensor, an electric field sensor, a data I / O (input / output) module, a signal transceiver and a timing module are arranged in the main body; the power supply module is electrically connected with a power distribution line and takes electricity from the power distribution line; the power supply module is electrically connected with the remote control switch and the signal transceiver respectively; the remote control switch is electrically connected with the current sensor, the electric field sensor and the signal transceiver respectively; the electric field sensor and the current sensor are electrically connected with the data I / O module respectively; the data I / O module is electrically connected with the signal transceiver; the signal transceiver is electrically connected with the timing module; a signal lamp is also arranged on the main body and is electrically connected with the signal transceiver. The on-line power distribution line monitoring acquisition terminal supporting the automatic resetting can be automatically reset after a period of set time when the fault of the power distribution line is eliminated, and the set time can be adjusted.

Description

technical field [0001] The invention relates to an on-line monitoring and collecting terminal for power distribution lines supporting automatic reset. Background technique [0002] Conventional on-line monitoring and collection terminals of power distribution lines usually reset by setting a timing after the flop action when the line fails. There are two problems with this reset method. One is that when the timing is set for a long time, the line fault has been processed and restored power supply, but the acquisition terminal is still in the reset state, and is still in the flop state. At this time, if the line fails again, the acquisition terminal cannot correctly indicate the fault location; The collection terminal will return, which will affect the repair personnel to locate the fault, which makes the collection terminal lose its proper function. In the actual use process, the first problem is common, which not only makes it impossible for the collection terminal to accu...

[0002] Conventional on-line monitoring and collection terminals of power distribution lines usually reset by setting a timing after the flop action when the line fails. There are two problems with this reset method. One is that when the timing is set for a long time, the line fault has been processed and restored power supply, but the acquisition terminal is still in the reset state, and is still in the flop state. At this time, if the line fails again, the acquisition terminal cannot correctly indicate the fault location; The collection terminal will return, which will affect the repair personnel to locate the fault, which makes the collection terminal lose its proper function

In the actual use process, the first problem is common, which not only makes it impossible for the collection terminal to accurately locate the second line fault that is approaching, but also increases the power consumption of the collection terminal (the light will flash after the flop), and shortens the time of the collection terminal. service life
