Problems solved by technology

However, the current alarm devices are all aimed at a single relay protection device, which are scattered in various places and do not form a systematic network. Special personnel are required to monitor each relay protection device or need special personnel to conduct patrols from time to time. Inspection is labor-intensive, and it is not convenient for overall monitoring of all relay protection devices in an area
[0003] Chinese patent CN103245835A discloses a data collection and intelligent analysis system for the operation status of relay protection devices. Data collection through a hand-held status collection terminal requires a lot of manpower, and it is not convenient to simultaneously monitor all relay protection devices in an area. overall monitoring

Embodiment 1

[0033] Such as figure 1 Shown is an embodiment of an integrated monitoring and warning device for a relay protection device 1 of the present invention, including several relay protection devices 1, a data acquisition module 2, a data transmission module 3, and a data recording and analysis module 4 that are electrically connected in sequence , also includes an alarm module 5 and a cloud platform 6, and the data recording and analysis module 4 is electrically connected to the alarm module 5 and the cloud platform 6 respectively.

[0034] As an embodiment of the present invention, the data acquisition module 2 includes a current acquisition unit 21, a voltage acquisition unit 22, a temperature acquisition unit 23, and a position acquisition unit 24; a current acquisition unit 21, a voltage acquisition unit 22, a temperature acquisition unit 23, and a position acquisition unit The input ends of 24 are all electrically connected to the input ends of the data acquisition module 2, ...

Embodiment 2

[0040] Such as figure 2 Shown is an embodiment of a monitoring method of the present invention using an integrated monitoring and warning device such as the above-mentioned relay protection device 1, comprising the following steps:

[0041] S1: using the data acquisition module 2 to acquire information of each relay protection device 1;

[0042] The collected results include the voltage, current, temperature and position of the relay protection device 1 .

[0043] The time control unit 25 in the data acquisition module 2 controls the acquisition frequency of the current acquisition unit 21 and the voltage acquisition unit 22 according to the temperature collected by the temperature acquisition unit 23. The higher the collected temperature, the greater the acquisition frequency.

[0044] S2: transmit the collection result to the data recording and analysis module 4 and the cloud platform 6 through the data transmission module 3;

[0045] S3: The data recording and analysis m...

Abstract

The invention relates to the technical field of relay protection devices, in particular to an integrated monitoring and alarming device of a relay protection device and monitoring method, and the integrated monitoring and alarming device of the relay protection device comprises a plurality of relay protection devices, a data acquisition module, a data transmission module and a data recording and analyzing module which are electrically connected in sequence, the device further comprises an alarm module and a cloud platform, and the data recording and analyzing module is electrically connected with the alarm module and the cloud platform. According to the invention, information of a plurality of relay protection devices at different positions can be automatically collected and monitored at the same time, an alarm is given when an abnormality occurs, a worker can master real-time dynamic states of the plurality of relay protection devices in one area at any time, and a problem source canbe found in time according to recorded data when a fault occurs. And the working efficiency can be greatly improved, and manpower resources can be saved.

Description

technical field [0001] The present invention relates to the technical field of relay protection devices, and more specifically, to an integrated monitoring and alarm device and a monitoring method for relay protection devices. Background technique [0002] In recent years, with the rapid development of power grid construction, various protection devices put into operation in power grids around the world have formed a certain scale. When the power components in the power system or the power system itself fail to endanger the safe operation of the power system, the relay protection device can send a warning signal to the operation duty personnel in time, or directly issue a trip command to the controlled circuit breaker to terminate these events An automated measure and equipment developed. However, the current alarm devices are all aimed at a single relay protection device, which are scattered in various places and do not form a systematic network. Special personnel are requ...
