Automatic, intelligent, integral, safe and quick cooling system for transformer

Abstract

The invention discloses an automatic, intelligent, integral, safe and quick cooling system for a transformer. The system comprises the transformer, an electromagnetic valve, a hand control valve, a pressure gauge, an umbrella shaped nozzle, a temperature sensor, a background monitoring machine, a temperature control instrument, a UPS (uninterruptible power supply), a spraying auxiliary device, alarm color indicator lights and an intelligent temperature control switch. The spraying auxiliary device comprises a galvanized water pipe, an auxiliary support, a high-voltage connection hose and magnetic attraction pieces; a safety shield is arranged at the umbrella shaped nozzle; the background monitoring machine and the temperature control instrument are connected with a remote/zero/local control switch. The system has the advantages that safety in water cooling for the transformer is improved, quickness in cooling of the transformer under the condition of unattended operations is realized, remote automatic monitoring and operation control of a control center are guaranteed, and intelligence, automation, high safety, convenience and quickness in operation, directness and effectiveness in cooling of the transformer are achieved.

Description

technical field [0001] The invention relates to the technical field of transformer cooling and cooling, in particular to an intelligent automatic integrated transformer safety and rapid cooling system. Background technique [0002] The main transformer of the hot summer substation operates under the extreme environment of high temperature and high load for a long time. If effective cooling measures are not taken in time, it will cause frequent tripping of the main transformer, and even equipment damage and burning of the main transformer. The explosion caused a large-scale power outage, seriously affecting the reliability of power supply and causing major economic losses. [0003] The stable operation of the transformer is related to the stability of the entire power grid. The temperature of the transformer is too high and the heat dissipation is not timely, but it often happens. When the temperature of the substation transformer is close to or exceeds the maximum temperatur...

Problems solved by technology

But now there are serious dangers and potential safety hazards in all the various methods of cooling transformers with charged water to cool down. If the water column or spray or water mist reaches a distance of several meters to more than ten meters, it will directly spray on the high-voltage bushing and the transformer inlet and outlet lines, which will cause direct or indirect grounding trips, or even serious personal equipment casualties.

It is precisely because all water spray cooling methods have such serious safety hazards, so in the operation of using live water spray cooling, operators must strictly wear professional labor protection equipment and take safety and technical measures, which seriously restricts this cooling method. Comprehensive and effective promotion and application in intelligent integrated automation and unattended substations
