BBP58防爆電動機(jī)調(diào)速變頻器外形舉例 Outline example

BBP-電動機(jī)調(diào)速變頻器可通過改變其輸出變頻來跳節(jié)普通三相異步電動機(jī)的轉(zhuǎn)速,以達(dá)到生產(chǎn)工藝的要求,或?qū)崿F(xiàn)節(jié)電的目的,節(jié)電率可
達(dá)到30%～60%,以可做為電動機(jī)軟啟動控制器,也通過傳感器,變送器等控制電路組成閉環(huán)調(diào)速系統(tǒng)。安裝操作簡單,起動平穩(wěn)無沖擊電
流（軟啟動）,電源容量大大降低,功率因數(shù)恒定（cosφ≈1）,同時具備故障顯示各種保護(hù)功能。
在隔爆外殼內(nèi)安裝11根紫銅管.增強(qiáng)自動通風(fēng)冷卻散熱.使隔爆腔內(nèi)變頻器能在正常溫度中工作。
由于調(diào)速變頻器的核心器件是單片微機(jī),因此具有很強(qiáng)的功能:
過電流保護(hù),短路保護(hù),過電壓保護(hù),欠電壓保護(hù),瞬時停電保護(hù)和斷相保護(hù)。
相數(shù)字顯示后或指示頻率,轉(zhuǎn)速以及負(fù)載率或電流等。
可手動調(diào)節(jié)頻率?？赊D(zhuǎn)速按時間變化的工藝曲線。也可以由DCS系統(tǒng)給出信號來控制其頻率。
本產(chǎn)品調(diào)速變頻器選用日本富士或SA-NKEN套件。柜內(nèi)還裝有電流表，電壓表，自動空氣開關(guān)，指示燈，交流接觸器，工頻變轉(zhuǎn)換開關(guān)

BBP-frequency converer board for motor control change speed of general three-phase asynchronous motor by means
of changing output frequency,which is suitable to processing technology and sa-ving energy up to 30%～60%,and
do as soft starting controller motor,by means of those circuits with sensor and speed adjustor the board could
make a loop frequency converter system.Operating is easy,st-arting without inpulse（soft staring）,so the source
capacity could be greatly becreased,power factor is constant（cosφ≈1）.It has fail-ure indicating and toher
protecting functions.

Because the key part of the frequency converter is a monolithic micro-computer,it works erriciently:
Protection of overcurrent,short-circuit,overvoitage,undervod-tage,instant power-off and phase.
Display of frequency speed and load with digital or pointer.
Designation of technology curve or speed by time.
Frequency converter of the board is selected form JAPAN's FUJI os SANKEN components or by user,Ammeter,
voltammeter,auto-airs-witch,indicating lamp and AC contactor are incuded.Operation mode could be besigned
according to suer's technology requirement.　
Connection with tube or throughwiring are included.
