The invention provides a transformer station cable adapter, and a transformer station protective apparatus connection structure and method. The transformer station cable adapter comprises a first connection section and a second connection section. One end of the first connection section and one end of the second connection section have adaptive interconnection terminals in order that the internal connection lines in the first connection section and the second connection section can be mutually communicated. The other end of the first connection section is provided with a switch cabinet connection terminal for being connected to a switch cabinet terminal bar. The other end of the second connection section is provided with a relay connection terminal for being connected to a relay protection device.
Description
technical field [0001] The invention relates to the field of electric power protection, in particular to a substation cable transfer joint, a connection structure and method for substation protection equipment. Background technique [0002] With the development of human society, the dependence on energy is getting stronger and stronger, and electricity has become an indispensable energy source. In the process of power transmission, the substation is an extremely important part, so the equipment safety of the substation will directly affect the reliability of power supply. [0003] The lifespan of existing substation equipment (also known as substation primary equipment, which is the main equipment for power transformation) is generally 30 years, while the lifespan of relay protection devices that are extremely important for protecting the safety of substation equipment is generally 10 years, so in The relay protection device needs to be replaced at least twice during the wo...
