Intelligent direct current screen used for opening and closing of high-low voltage switch

Abstract

The invention discloses an intelligent direct current screen used for opening and closing of a high-low voltage switch. The intelligent direct current screen comprises an alternating current power distribution unit, a high-frequency switch power supply module, a direct current power distribution unit and an intelligent monitoring unit, wherein the intelligent monitoring system comprises an intelligent monitoring unit, an alternating current detection unit, a direct current detection unit, a switching value detection unit, a charge module, a battery polling unit, an insulation polling unit, a communication module, an inverter module, a computer background and a touch display screen; the alternating current detection unit, the direct current detection unit, the switching value detection unit, the charge module, the battery polling unit, the insulation polling unit, the communication module and the inverter module are directly connected with the intelligent monitoring unit; and the computer background and the touch display screen are respectively connected with the intelligent monitoring unit. The intelligent direct current screen for opening and closing of the high-low voltage switch has the advantages of reasonable structure, high reliability, capability of being communicated with an upper computer for realizing remote control, capability of meeting the requirement of high automation degree and unattended operation, and better practicability.

Description

technical field [0001] The invention relates to a DC screen, in particular to an intelligent DC screen for opening and closing high and low voltage switches. Background technique [0002] The existing DC power panel of the substation uses a charger and a floating charger to charge the battery, and the charging and floating chargers are mutually standby, and the charging and floating charging switching device is manually controlled to switch their working states. Generally, every three months or half a year, the operator will switch the battery to the charger for equalizing charging. After charging for 24 hours, the charger will be automatically cut off, and the floating charger will perform long-term floating charging on the battery. During this period, operators need to manually check and record the charging voltage and single battery. At the same time, the AC power supply system of the AC power distribution panel in the substation is controlled by separate components, the...
