Abstract

The invention provides an energy-saving and emission-reduction intelligent underground transformer. The energy-saving and emission-reduction intelligent underground transformer comprises a shell, a side-mounted oil level gauge and a multifunctional transformer protector; the side-mounted oil level gauge and the multifunctional transformer protector both are mounted on the sidewalls of the shell. The output signals of the oil level gauge, an overvoltage alarm device, a gas alarm device and a temperature alarm device are transmitted to a network via a communication interface by use of a controller so that a central management computer connected in the network is capable of remotely monitoring each underground transformer, and as a result, transformer current differential protection, transformer differential current quick-break protection, transformer overcurrent backup protection, overvoltage protection, current measurement, voltage measurement, temperature measurement, power factor measurement and harmonic measurement are realized; in case of alarm events such as open circuit, short circuit, overload, overheat, undervoltage and power failure, corresponding processing is carried out locally and alarm information is transmitted to the central management computer by use of a network interface, and therefore, lots of underground transformer parameters can be monitored centrally.

Description

Technical field: [0001] The invention relates to the field of electricity, in particular to power transmission and distribution technology, in particular to a distribution transformer, in particular to an intelligent underground transformer for energy saving and emission reduction. Background technique: [0002] Underground transformers operate in poor environmental conditions and are generally placed in pits and wall pits. With the increasing power consumption, the safety and reliability of power distribution is becoming more and more important. The underground distribution network is composed of underground transformers, wiring cabinets and distribution lines. The safety and reliability of underground transformers determine the safety and reliability of distribution network operation. Due to the scattered distribution of underground transformers and the large interference, the communication between underground transformers is relatively difficult, and it is difficult to re...
