Description

Anti-theft alarm for distribution transformer

Technical Field

Background

The distribution transformer is called 'distribution transformer' for short, and is a static electric appliance which transforms alternating current voltage and current according to the electromagnetic induction law in an electric distribution system and transmits alternating current energy. In some areas, power transformers with a voltage class of 35 KV or less (mostly 10KV or less) are called "distribution transformers", and are referred to as "distribution transformers" for short. The place and place for installing the distribution transformer are the transformation substation. A distribution power transformer is a stationary electrical device that is used to transform an alternating voltage (current) of a certain value into another voltage (current) of the same frequency or different values. When the primary winding is energized with an alternating current, an alternating magnetic flux is generated, and the alternating magnetic flux is magnetically conducted through the iron core, so that an alternating electromotive force is induced in the secondary winding. The level of the secondary induced electromotive force is related to the number of turns of the primary winding, i.e. the voltage is proportional to the number of turns. The main role is to transmit electrical energy, and thus, the rated capacity is its main parameter.

Because the distribution transformer is mostly installed on a column or installed on the ground in the open air, the distribution transformer is often damaged, and a copper core of the transformer is stolen, so that great harm is brought to normal electricity utilization of people. The existing anti-theft equipment is too obvious, and the monitoring equipment can be obviously seen when the anti-theft equipment is installed on a transformer rack, so that the anti-theft equipment is easily damaged by thieves in advance, and the anti-theft equipment cannot be used for the events of destructive low-transfer transformers.
