Overview

Floor type boundary switch integrated prepaid metering device is a column on the high-voltage metering, switch, control box to cabinet structure of the product, by the whole pouring dry type high-voltage metering box and ZW32F type intelligent boundary switch combination, the box is made of stainless steel or iron plate spray plastic material. This product is easy to install on the structure, beautiful appearance, the high voltage part is completely isolated from the low voltage meter room, and the high voltage room can not open the door operation under the condition of the equipment live, only in the case of power failure can the high voltage room door open, safe and reliable. The product occupies small area, is the living area, the industrial and mining enterprise and the box type change matching uses the perfect combination product. Personnel can directly open the door to view the bottom of the table and on-site operation switch action. The transformer adopts vacuum pouring of fully enclosed epoxy resin, so the aging problem is eliminated. The dividing switch part adopts vacuum switch with zero sequence and protection current transformer, and realizes zero sequence, overcurrent and quick break protection with intelligent controller, which can automatically remove single phase grounding fault and automatically isolate phase short circuit fault. To ensure the safety of non-fault users. This product has the FTU function to realize the switch remote control switch opening and closing; also has the GPRS remote control function (for details, see the following “Intelligent Controller Instructions “)
