发电机组测试负载柜

Load Banks are designed to provide a stable and controllable load for determining the performance characteristics of AC generators. A load bank verifies the rated power of a generator set; it verifies if the engine is properly sized of has the sufficient mechanical power (kWm) to the drive the alternator at full load; it checks the efficiency of the cooling system; it detects problems of the generator; it decarbonizes engine and prevents wet stacking of diesel engine in generators operating on light load.

Designed for durability and convenience with its heavy duty casters for mobility during generator load testing. Uses low heat emitting resistive elements to minimize heat conduction. Metal sheathed elements with cooling fins made from high grade nickel resistance wire in U-type form. Built in heavy duty industrial fan blowers as cooling system of the unit. These blowers can be powered internally by the dummy load itself or by external power supply.

Load Bank Technical Specifications

1. Resistive type of load, PF = 1.0. Stainless steel sheathed elements manufactured from high grade magnesium oxide.

2. Rated testing voltage: AC 3P4W, 110-480V 50/60 Hz.
3. Cooling mode: Forced air-cooled, fans mounted on the side of the load bank blow horizontally. Testing power or external utility power supply for fans.
4. Working mode: Load step control
Total testing capacity ranges from 0kw to the max consisting of 10kw, 20kw, 50kw, 100kw load setting switches plus a 0-10kw fine-tuning knob. From 0kw to the max, any load combination is achievable. Load step resolution is 10kw.
5. Load bank features world-famous components to ensure reliable performance:
6. Parameter measuring accuracy grade: 0.5.
7. Load control accuracy: ±3%.
8. Load bank protections: Overheating protection, cooling fans failure protection and over load protection with alarm.
9. Control mode: Two control modes available:
