Description

A wiring device for comprehensive test of transformer

technical field

The utility model relates to a wiring device, in particular to a wiring device used for a comprehensive test of a transformer.

Background technique

Power transformers are one of the main equipment in power plants and substations. The role of the transformer is multifaceted. It can not only increase the voltage to send electric energy to the power consumption area, but also reduce the voltage to the voltage used at all levels to meet the needs of power consumption. In short, both step-up and step-down must be done by the transformer. In the process of electric energy transmission in the power system, two parts of voltage and power will inevitably be lost. When the same power is transmitted, the voltage loss is inversely proportional to the voltage, and the power loss is inversely proportional to the square of the voltage. Using the transformer to increase the voltage reduces the power transmission loss.

Voltage transformers are usually set up at a height of about 4 meters. Therefore, during the test process for power transformers, workers need to climb to a position of 4 meters high for wiring, and then conduct transformer tests on the bottom surface. However, the same power transformer often needs to carry out multiple tests. For this reason, every time a test is carried out, the staff needs to climb up to connect and then climb down to detect, which is both laborious and time-consuming. The wiring device used for the comprehensive test of the transformer required for multiple tests is particularly necessary.
