宝安Outdoor high-voltage split-type prepaid metering device
Product Description
Product Overview
This product is a combination of a high-voltage metering device and a ZW43 intelligent sectionalizing switch, suitable for outdoor power systems with a rated frequency of 50HZ and a rated voltage of 10KV or less for electricity metering. The current transformer uses fully enclosed epoxy resin vacuum casting, thus eliminating aging problems. The sectionalizing switch uses a vacuum switch and is equipped with zero-sequence and protective current transformers. It achieves zero-sequence, overcurrent, and fast-break protection with the intelligent controller, automatically cutting off single-phase ground faults and automatically isolating interphase short-circuit faults, ensuring the power safety of non-faulty users. This product has FTU function to realize remote control of switch on/off; it also has GPRS remote control function (see "Intelligent Controller Description" below for details). This prepaid combined current transformer realizes the basic functions of a prepaid high-voltage metering box through a prepaid control terminal, such as prepayment of electricity fees by users, reminders before arrears, tripping after arrears, and delayed alarm. This product is easy to install and has a beautiful appearance.
