The application of UPS in operation power supply of high voltage switchboard

In order to meet the increasing requirement of modularization and interconnection for the high voltage switchboard monitoring systems,this article introduces an online monitoring system based on the embedded system.

In this paper,the radio frequency signal used to on line monitor the partial discharge in high voltage switchboard is studied.

High-voltage switch cabinet development and present situationanalysis;

The cause of failure in high-voltage switch cabinet model 35KV is analyzed from insulation and structure and some countermeasures are introduced in order to avoid such failure.

In order to solve this problem, this thesis puts forward on-line temperature monitoring system of contact inhigh-voltage switch cabinet that integrated different technical subjects, such as optical fiber sensingtechnology, advanced computer technologies both in hardware and software, the technologies of intelligent.

Over-temperature detection for isolated contacts in high voltage switchgear;

Design of early warning temperature system based on the supervision of king view for the high voltage switchgear

By the fiber grating as temperature sensor,the on-line monitoring system of temperature for the contact inside the high voltage switchgear was put forward.

The Research on the High Voltage Switch Cabinet On-line Temperature Monitoring System;

Using IR temperature measurement technology, a temperature real-time monitoring network for high voltage switch cabinet based on thermopile sensor is developed.

For monitoring temperature of substation high voltage switch cabinet conveniently,reliably and real-timely,the temperature monitoring system based on CAN bus and wireless radio frequency technique was developed.
