JYF-0.5低壓預(yù)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(tǒng)的電能計量。 當預(yù)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(yù)付費呂的， 解決了電力部門電費難收的問題。
本產(chǎn)品在變壓器的二次側(cè)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(chǎn)品也可加裝短路錨， 增加變壓器的保護功能（過流速斷）。 更適宣臺區(qū)、 照明、 排灌及工礦等用電場所， 不需要建立配電室，直接實現(xiàn)柱上安裝， 減少占地， 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.

本產(chǎn)品由控制柜和預(yù)付費電能表箱組成控制柜直接安裝在變壓器二次出線上， 變壓器二次出線直接接交流接觸器進線側(cè)， 交流接觸器出線側(cè)的出線穿過母線型電流互感器， 接置于控制柜頂部的套有瓷瓶的螺桿， 螺將作為用戶接線之用。預(yù)付費電能表箱內(nèi)電能表不僅能計電費而且當無電費時， 電能表的控制回路使控制桓動作， 切斷電源， 達到有費供電無費斷電的目的。

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.
