Power distribution automation power-outage-free debugging equipment and working method thereof

Abstract

The invention provides power distribution automation power-outage-free debugging equipment and a working method thereof, relates to a power equipment debugging device, and in particular relates to a debugging device for a power distribution automation main station and a power distribution terminal and a working method of the debugging device. The invention provides the power distribution automation power-outage-free debugging equipment which requires a small number of personnel, is high in safety and easy for wire connection and cannot affect power supplying (no power outage) of a power grid during testing, and a working method of the power distribution automation power-outage-free debugging equipment. An industrial control main board and a core control board are respectively fixed in a shell, and the industrial control main board is connected with the core control board through a communication line; a power board is fixed in the shell, and the power board is connected with the industrial control main board and the core control board respectively through power lines so as to supply power to the industrial control main board and the core control board; and a power socket is arranged on the power board and is connected with an external power supply. The whole power distribution automation power-outage-free debugging equipment is small in size and is portable, the number of required personnel is small, and the original operation and maintenance electric protection work cannot be affected.

Description

technical field [0001] The invention relates to a power equipment debugging device, in particular to a distribution network automation master station and a power distribution terminal debugging device and a working method thereof. Background technique [0002] Under normal circumstances, the 220V AC power supply of the PT secondary circle of the ring main unit is converted through the power management module of the power distribution terminal (DTU) to obtain the DC 24V working power used by the power distribution terminal (DTU), and the power distribution terminal ( DTU) has a built-in battery, which can store DC power, and the stored DC power can provide DC 24V power in a short period of time in the event of AC voltage loss, so as to cooperate with the completion of telemetry, communication and remote signaling functions required electrical energy. In addition, the 220V AC power supply of the PT secondary circle of the ring network cabinet will be connected to the UPS unin...

Problems solved by technology

However, it needs to be operated in a power outage state, the wiring is complicated, and it is prone to misconnection and misconnection, which not only affects the stability of power supply and the safety of the power grid, but also is prone to safety accidents and threatens personal safety.

Moreover, too many personnel are required for testing, which affects the normal operation and maintenance order and is not conducive to the stability of the power grid.
