            產品特點 Feature of product

            TBP 三相組合式過電壓保護器是一種新穎的過電壓保護器件,主要用于35KV 及以下電力系統,保護變壓器、開關、電動機、并聯補償電容器等電氣設備,可限制大氣過電壓及各種真空斷路器引起的操作過電壓,對相間和對地過電壓均能起到可靠的限制作用。

            TBP三相組合式過電壓保護器由四只避雷器組成四星形接法,從而使各相地、相間的過電壓都得到保護。由于結構上的巧妙配合,一組過壓保護器可起到相對地保護作用。同時克服了簡單的三只避雷器星形接法不能更好保護相間過電壓的缺點。

            三相組合式過電壓保護器是針對現行單只避雷器過壓保護的弱點設計的一種新型組合式過電壓保護器。該保護器由四只避雷器組成,具有其它同類產品不可比擬的特點和優點。

            本產品選用阻燃、耐老化的硅橡膠做外殼材料,從內部引出四根硅橡膠高壓電纜和氧化鋅閥片整體硫化一次模壓而成,故其電氣絕緣性能好、介電強度高、密封性能好、抗電蝕、耐老化,而且體積小、安裝方便,無需考慮相間距離和爬電距離,可根據現場情況靈活安裝。

            TBP Three phase composite over-voltage protector is a new and original over-voltage protective device. It is used in AC power system for under 35KV to protect the electric equipment insulation for transformer, motor, paralleled compensation capacitor, etc. This product can limit to atmosphere over voltage and operation over voltage caused by vacuum breakers, in addition, it can play secure limitation to over voltage of the phase to phase and the phase to earth.

            TBP three phase composite type over-voltage protector connects with four stars type by four arresters composing diagram, so that every phase to ground and phase to phase over voltage can be protected. because of the clever mating, one set arrester takes phase to earth protective affect. Meantime, overcoming fault that simple three arresters star shape connecting can not protect the phase to phase over- voltage better.

            Three-phase composite type over-voltage protector is designed in the term of faults of current over voltage protector. This protector includes four groups ZnO valve elements, it has the super excellent features that other similar products can not compete with it.

            The housing of this product is made of flame-resistance and anti-aged silicon rubber, because four HV cables made of silicon rubber can be leaded out, and the whole of ZnO valve element is proceeded integrated sulphation and primary die stamping, the protector can show many advantage such as good electric insulation, high dielectric strength, anti-electric corrosion, anti-aged, small volume, convenient insulation, the distance among phases and creepage distance can not be considered, the protector can be installed flexibly in the term of location.

            使用注意事項Use notes

            過壓保護器在投入前和運行一年后,應按以下要求做檢測試驗:

            1、直流V1mA的測量:

            分別在過壓保護器的A與D、B與D、C與D和A與C、B與C、A與B端施加直流電壓,待流過其電流穩定于1mA后,讀出電壓值并要求不低于其規定值為合格。并做記錄,超標更換。建議每年檢測一次。

            2、直流漏電流測量:

            分別在保護器的A與D、B與D、C與D和A與B、A與C、B與C端施加75%V1mA電壓待穩定后,讀出電流值,應不大于50μA為合格。在投入運行前檢測,建議每年檢測一次。

            3、過壓保護器所保護的電氣設備做耐壓試驗時,應將其退出。

            4、卸裝本產品時,嚴禁用手提電纜線。

            The over-voltage protector should be tested before use after operation each year as following testing items:

            1、Test of DC U1mA voltage

            CD voltage is applied to A-D、B-D、C-D、A-C、B-C and A-B terminals respectively. After the current stabilized to 1mA,record the voltage value. If the voltage value is large than specified value,the protector qualified. Recommend that test one time each year.

            2、Dc leakage current

            DC 75% U1mA voltage is applied to A-D、B-D、C-D、A-B、A-C and B-C terminals respectively. After voltage becomes stabilization, record the current value. If the current value is not large than 50μA,the protector is qualified. This test should be done before use. Recommend that test one time each year.

            3,When doing the voltage-withstand test,the electric equipment protected by the over- voltage protector should be disconnected.

            4、When dismounting the over- voltage protector,can not carry the leads of the over-voltage protector by hand.
