Background
The transformer substation is an important part of a power system, and is a place for converting voltage and current, receiving electric energy and distributing the electric energy. The transformer substation is complex in structure, and main electrical equipment is divided into primary equipment and secondary equipment. The primary equipment refers to equipment for directly producing, conveying, distributing and using electric energy, and mainly comprises a transformer, a circuit breaker, an isolating switch, a current transformer, a voltage transformer and the like. The secondary equipment of the transformer substation is equipment for measuring, monitoring, controlling and protecting the operation conditions of primary equipment and a system, and mainly comprises a relay protection device, an automatic device, a measurement and control device, a metering device, an automatic system and direct current equipment for providing power for the secondary equipment. The secondary equipment inner terminal row connects the circuits of the on-screen equipment and the off-screen equipment to play a role in signal (current and voltage) transmission.

In order to ensure the long-term stable operation of the power grid, the substation equipment needs to be frequently subjected to power failure maintenance. The secondary equipment is routinely overhauled, and when the primary equipment fails, the secondary equipment can normally act to quickly remove the failed primary equipment, so that the normal operation of a power grid system is ensured.
During secondary equipment maintenance, in order to prevent the normal operation equipment from being affected by work, secondary wiring connecting equipment such as a protection screen, a control collection box and a mechanism box with the operation equipment is generally required to be removed. In order to prevent the exposed metal wire end of the dismantled wiring from mistakenly touching the operation terminal, being directly grounded and the like, the exposed wire end needs to be subjected to insulation treatment. When secondary equipment is routinely overhauled, according to a secondary safety measure ticket, secondary wiring of equipment such as a protection screen, a control collection box and a mechanism box is removed, and then the secondary wiring is wrapped by an insulating tape. And the number of the terminal for removing the wiring is written on the insulating tape by a marking pen according to the terminal row number so as to be used when the wiring is recovered. However, the secondary equipment is usually required to work for several days in routine maintenance, and the insulating tapes may fall off and lose the function; the number of the terminal for removing the wiring is written on the insulating tape by using a marking pen, and the terminal is not easy to identify when the wiring is recovered.
