Embodiment Construction
[0038] In order to make the purpose, technical solutions and advantages of the present application, the present application will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended to explain the present application and is not intended to limit the present application.
[0039] The carry-down switch of the transformer is gradually mainstream as a flexible and convenient mounting switch. Take a load-bearing switch VR type as an example, including a plurality of groups of main disconnect contacts, main contacts, and switching switches, and transformers are sequentially closed and broken by passing the main contact, the main contact, and the conversion switch in a certain order. Open, thereby changing the effective turns of the transformer winding access circuit, thereby changing the voltage ratio of the transformer, achieving the purpose of the pressure regu...
