Problems solved by technology

[0002] At present, power supply enterprises have invested heavily in the construction of intelligent power distribution equipment for public transformation, and have also achieved the purpose of remote monitoring, remote parameter adjustment and fault early warning. However, after automatic isolation and alarm of fault points are realized, operation and maintenance personnel are usually required to go to the site To check the fault point, if the fault point is eliminated, the operation and maintenance personnel also need to restart

Embodiment Construction

[0020] Combine below Figure 1 to Figure 3 The present invention will be described in detail.

[0021] A method for remote monitoring of fault information of a low-voltage power distribution cabinet. A controller is provided in the low-voltage power distribution cabinet, and the controller communicates with Flash memory, GSM and GPRS communication modules. The fault monitoring point of the low-voltage power distribution cabinet is provided with a data collection point. The controller communicates with the data collection point to collect data. A data channel is set in the controller corresponding to the data of each data collection point. The counter in the controller records the channel number and the number of data collection times, and the warning value is pre-stored in the controller. and alarm value, during the operation of the low-voltage power distribution cabinet, the remote monitoring of fault information executes the following procedures in sequence:

Abstract

The invention discloses a low-voltage power distribution cabinet fault point self-healing method. The method involves trying power delivery for one time when actually acquired data is above a preset early warning value and is below an alarm value to help operation personnel to determine whether a fault is caused by a too high load in a short period. The self-healing success rate by use of the method can reach about 40%, and besides, during an execution process, even in case of a short-time fault, power supply can be recovered for short time so that urgent needs of clients can be met before the operation personnel arrive at a field to deal with the fault.

Description

technical field [0001] The invention relates to a self-healing method for a fault point of a low-voltage power distribution cabinet. Background technique [0002] At present, power supply enterprises have invested heavily in the construction of intelligent power distribution equipment for public transformation, and have also achieved the purpose of remote monitoring, remote parameter adjustment and fault early warning. However, after automatic isolation and alarm of fault points are realized, operation and maintenance personnel are usually required to go to the site To check the fault point, if the fault point is eliminated, the operation and maintenance personnel also need to restart. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a self-healing method for fault points of low-voltage power distribution cabinets, so as to realize automatic checking and automatic recovery of fault points. [0004] In order to so...
