JYF-0.5低壓預付費計量裝置， 主要適用于額定頻率為50Hz或60Hz， 額定電壓為0.5kV及以下系統的電能計量。 當預付費電能表輸入卡有電費信號輸入時， 可正常供電， 一但無電費， 則計量箱自動斷電， 達到預付費呂的， 解決了電力部門電費難收的問題。
本產品在變壓器的二次側加裝了防竊電封盒， 用電纜直接引入綜合計量箱中， 杜絕了竊電。
本(ben)產品也可加裝短路錨， 增加變壓器的(de)保護功能（過流速斷）。 更適(shi)宣臺區、 照(zhao)明(ming)、 排灌(guan)及工礦等用電(dian)場所， 不需要建(jian)立配電(dian)室，直接(jie)實現(xian)柱上安裝， 減少占地， 方便維(wei)修。

   

JYF-0.5 type low voltage pre paid power metering device. suitable for 50Hz or 60Hz three-phase AC rated voltage of 0.5kV power grid for electric metering. When the prepayment electric energy meter input card has electricity signal input, can be normal power supply, but no electricity, the metering box automatically power off, to achieve the purpose of prepaid, to solve the problem of electricity tariff collection.
This product in the two side of the transformer with anti-theft seal box, cable directly into the integrated metering box, prevent theft.
This product can also be equipped with a circuit breaker to increase the protection function of the transformer (over cur­rent velocity). More suitable for Taiwan area, lighting, drainage and mining in the field, does not need to set up a distribution room. direct installation, reduce the area of column. convenient maintenance.
