一、產(chǎn)品介紹

    HAVD系列晃電繼電器用于***重要電動機(jī)在電源故障情況下能順利自啟動。

當(dāng)電機(jī)有失電時，在0-10s(可調(diào))時間內(nèi)，輸出接點(diǎn)保持閉合狀態(tài)，若故障為晃電，則恢復(fù)供電后通過

由本接點(diǎn)構(gòu)成的自保持回路，電機(jī)重新啟動;如故障為***性故障，則接點(diǎn)延時斷開。(適用于交流50/60Hz)

HAvD series of anti voltage drop relays are used to ensure the successful startup of electrical motorsby itself in case of power failure.

When power drops out in an electrical motor, with in 0-10s (adjustable), the output contacts remainclosed.In case of interruption of power supply, the electrical motor restarts by itself as soon as thesupply is resumed through the self-held loop composed of the contacts in the relays.If the failure ispermanent, the break of contacts will be delayed. (Are used in AC 50/60Hz)

二、技術(shù)參數(shù)

  “晃電”允許時間Tm AllowableTimeforInterruption of Power:0~10s

額定電壓NominalVoltage:220VAC±10%

時間調(diào)整級差Gradation ofTime Adjustment:1s

觸點(diǎn)容量Contact Capacity:在電壓不大于250V時:觸點(diǎn)長期接通電流為5A;在電壓不大于250V時:電路時間常數(shù)L/R為5mS的直

流電路中，觸點(diǎn)斷開容量為50W;在電壓不大于250V時:功率因數(shù)COS6為0.4的交流電路中，觸點(diǎn)斷開容量為250VA。

When the voltage is less than 250V,the continuous current o f the contacts is 5A; When the voltage is less than 250Vandtime constant L/R is 5mS in the DC circuit, the switching capacity of the contacts is 50W;When the voltage is lessthan 250Vand the power factor COSgis 0.4in the AC circuit, the switching capacity of the contacts is 250VA.

介質(zhì)強(qiáng)度DielectricStrength:繼電器各引出端子與外殼之間，應(yīng)能承受50Hz、2KV，歷時1分鐘耐壓試驗(yàn)而無擊穿或閃絡(luò)現(xiàn)象

50Hz, 2KV, 1 minute between each ofthe contactsand the casing, and no sign of breakdown or flashoveris detected.
