Oil immersed distribution transformer installation site selection

installation: oil immersed distribution transformer can be installed one way of hanging rod, pole selection of 12 m or 15 m heavy cement rod cement pole. 

installation site selection: After investigation, we found that single-phase distribution transformer installation site less restricted by geographical factors, the nature of the load factors and more. In general: 

When the 11kv single phase transformer power supply radius is too large, causing the end of the supply voltage is low, affecting the normal use of electricity users, in single-phase power supply end of the installation of distribution transformers, cutting low voltage network, reducing the radius of low-voltage power supply, solve the problem of low voltage users.When the three-phase distribution transformer overload, according to the load characteristics, select the appropriate extensions installed single-phase distribution transformers, cutting transfer of load, solve the problem compatibilization 

in the residential area where non-user installation of three-phase power distribution transformers single-phase power supply to the residents, can shorten the radius of low-voltage power supply, reduce loss in load density, widely distributed, without the user’s place of three-phase power distribution transformers installed single-phase power supply, saving investment, power point to solve the problem. 

Small single-phase transformers Introduction

Transformer is passed through the electromagnetic coupling between electric power equipment, use can be summarized as follows: supplying electric power economy, a reasonable allocation of power, safe to use electricity. In fact, while it is changing the current transformer, the resistance may change
Reactance and number of phases. Single phase transformer which has a small capacity, light weight, simple wiring, easy to install, etc., referring to the small transformer capacity 1000V.A of transformers (for example, 11kv single phase transformer). The easiest small single phase transformer core consists of a closed (constituting a magnetic circuit) and wound around the core of two different turns, insulated from each other windings (circuit configuration) composition. Such applications Transformer in life is very extensive.
