Remote management method and system for power grid switchgear based on cloud platform

Abstract

The invention provides a power grid switch cabinet remote management method based on a cloud platform and a management system using the method, the management method comprises an initialization starting stage and a conventional operation stage, and the management system comprises a cloud platform server, total power distribution equipment and a tail end switch cabinet; the initialization phase ofthe management method is executed when the cloud platform server, the main power distribution equipment and the tail-end switch cabinet of the management system are in paired connection. In a conventional operation stage, a specially designed tail-end switch cabinet detects and records all power distribution data and refrigerating capacity; the information is sent to a cloud platform for big dataanalysis; the heating condition of the tail-end switch cabinet is judged through the refrigerating capacity; average distributed power is used as a control standard value of power distribution for automatic power distribution, actual total load power is reduced as much as possible under the condition that normal operation of all devices is guaranteed, and the management method and the management system have the advantages of large-area regional linkage management, capability of assisting in detection of heating conditions and the like.

Description

technical field [0001] The invention belongs to the technical field of intelligent management of switch cabinets, and in particular relates to a remote management method for a power grid switch cabinet based on a cloud platform, and also relates to a switch cabinet management system using the method. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch, and each branch is set according to its needs. Such as instrumentation, automatic control, motor magnetic switch, various AC contactors, etc., and some also have high-voltage chambers, low-voltage chambers and insulating gas chambers, etc., which are suitable for distribution automation. [0003] At present, the use of switch cabinets is becoming more and more common, and power distribution is becoming more and more automated. However, most of the current switch cabi...

AI Technical Summary

Problems solved by technology

[0003] At present, the use of switch cabinets is becoming more and more common, and power distribution is becoming more and more automated. However, most of the current switch cabinets are independent switch cabinets, and there is a lack of communication linkage between them, so that the current distribution automation is only in a small range. Automation, it is difficult to realize large-area switchgear linkage and power distribution automation, and the current power distribution method is usually to classify power equipment. Once overload occurs, power distribution equipment will shut down power distribution with lower priority. The purpose of reducing the total load of electrical equipment, the sudden shutdown of electrical equipment will affect the user experience and cause certain impact

[0004] In addition, the electrical components in the inflatable cabinet will generate a certain amount of heat after long-term use, especially in the inflatable cabinet that has been in service for a long time, it is inevitable that some electrical components will be aging, and the connection parts of the switch will be in poor contact, which will cause more serious heating

Since the inflatable cabinet is filled with sulfur hexafluoride gas, it is generally sealed and connected, so that the internal heat cannot be easily dissipated, and it is easier to cause the temperature in the cabinet to be too high, which will further affect the operation of the internal electrical components, cause damage, and even cause fire and explosion. Waiting question

However, the current switchgear lacks self-test functions such as temperature and aging.
