Description
Technical Field
The invention relates to the technical field of transformers, in particular to a power transformer convenient to install.
Background
A power transformer is a stationary electrical device that is used to transform an ac voltage and current of a certain value into another voltage and current of the same frequency or different values. Power transformers are one of the main devices of power plants and substations. The transformer has the functions of increasing voltage to transmit electric energy to an electricity utilization area in many aspects, and reducing the voltage to use voltages of all levels to meet the requirement of electricity utilization. In any case, both the step-up and step-down must be done by a transformer. In the process of transmitting electric energy in a power system, voltage loss and power loss are necessarily generated, wherein the voltage loss is inversely proportional to the voltage when the same power is transmitted, and the power loss is inversely proportional to the square of the voltage. The voltage is increased by the transformer, and the power transmission loss is reduced.
When traditional power transformer installed, pass through the mount with power transformer and install on the shaft-like thing usually, because for high altitude construction, in order to reduce personnel high altitude construction's risk, mount and shaft-like thing are single locking generally and are embraced tightly, and the result that the single was held tightly leads to is lower for embracing the degree of tightly, and wind resistance is relatively poor when meetting bad weather, the condition that becomes flexible probably appears, thereby leads to the transformer gliding to cause the condition that the transformer damaged.
