STC Series three-phase third-harmonic a.c. synchronous generators are mainly designed to serve as power generating unit for lighting purpose in villages , towns, and house-hold electric appliances or standby power.The construction of the generators are salient-pole rotating field , self excitation with third-harmanic . The generator interior is made of high quality magnetic and electrical materials, and easy to maintenance. The characteristic of generators see as the followings:
1. The generators are designed as per standard JB/T3320.2-2000. And in conformity to IEC34-1.
2. Insulation is class B or F, drip-proof type is IP21,
3. Tight in construction for casting frame; If our customers ask for steel constuction,we can meet .
4. The generators are three-phases with output four terminals, connectiong for the star connection, 400V rated L-L voltage, 230V rated L-N voltage, 50Hz, 0.8P.F.。If our customers ask for 60Hz or diferenent voltage, we can meet .
5. Generally the generators are two-bearing comstuction, also can produce for single-bearing constuction; They can be coupled with engine s by leather belt, and can ratote in two different direction.
6. The steady voltage regulation of generators are good in 3% speed variation, load from no-load to full-load and power factor from 0.8 to 1.0。
7. The voltage regulation of generators are excellent, and the capability for directly-starting motor also is fine。
The requirements for environment:
1. Altitude: not exceed 1000m.
2. Cooling air temperature: 258~313K (-15oC~40oC).
3. Relative air humidity: not exceed 90%.
