Summary of product
The product is used for cost-controlhigh voltage metering in AC 50Hz, 6-10kV three-phase power system. DGZZ-10smart power grid cost-control metering equipment consists of high voltage vacuum load switch, dry type combined instrument transformerused for metering, meter box with anti-theft functionand others. Special winding is also set for combined instrument transformerand used as opening and closingmechanism power supply of switch( 220V). Meter box with anti-theft function consists of prepayment meter, multi-functional meter andhigh voltage switch control circuit: it has features such as small size, convenient installation, high metering precision, anti-electricity stealing, cost-control and load control..
Brief introduction of structure
1. DGZZ-10smart power grid cost-control meter box device consists of high voltage vacuum load switch, dry type combined instrument transformer used for metering,meter box with anti-theft functionand others.High voltage vacuum load switch anddry type combined instrument transformer used for meteringare sealed by fully-enclosedactive partof box(please refer to figure I).Metering wire and control wire are sealed using armor sleeve and accessed to meter box where prepayment meter, high voltage switch control circuit andanti-electricity stealingmodule andentrance guard circuit are set. It solves problem of stealing electricity under the state of powering on and powering off.If door is opened by user without permission, it shall trip and be powered off.It cannot be powered on until power management personnel handle and decrypt.It has features of simple structure, convenient use and others.
2. Meter box combines with load control to realize remote control and remote metering and can completely meet management requirements of smart power grid.
3. The product has features of compact structure, convenient installation, flexible structure design and others, which facilitates popularizing in smart power grid.
