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。
本產品(pin)也可加裝短(duan)路錨， 增(zeng)加變壓器的保(bao)護(hu)功能（過流速(su)斷(duan)）。 更適宣臺區、 照明、 排灌(guan)及工礦等用電場(chang)所， 不需(xu)要建立(li)配(pei)電室，直接實現(xian)柱(zhu)上(shang)安裝， 減少占(zhan)地(di)， 方便維修。

   

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.

本成品由有效配電柜和預收費能量表箱組合而成有效配電柜直觀怎么安裝在變電器分次出網上， 變電器分次出線直觀接討論會打交道器進線側， 討論會打交道器出線側的出線蓋過母線型工作電流互傳感器， 接放置有效配電柜上邊的套有瓷瓶的螺桿式， 螺將當作普通用戶接線兩端的用處。預收費能量表安裝有能量表不僅能能計交水電費而當無交水電費時， 能量表的有效操縱二次回路使有效操縱桓操作， 掐斷主機電源， 超過有費變電無費停電的意圖。

This product is composed of a control cabinet and prepayment meter box control cabinet directly installed in the transformer two wire, two wire transformer is directly connected to the inlet side of AC contactor, AC contactor outlet side of the outlet through the bus type current transformer is connected with the top of the control cabinet set a porcelain screw, screw as a user connection wire. Pre­paid electric energy meter box electric energy meter can not only account for electricity, and when no electricity, electric energy meter control circuit to control cabinet action, cut off the power supply, to achieve the purpose of power consumption without charges.
