The above-mentioned disappearance that its purpose of the utility model exists for the solution prior art, and a kind of electrical load device that operates steadily, regulates the generator load test that fluctuation is little, the load ability to bear is big that proposes.It is made up of with gearing and electric control box, remote-control box and stube cable the mechanism that comprises water resistance container and connected water lines, container internal polar plate and the lifting of control pole plate, is characterized in:
The water resistance container is a round tank body structure;
Adopt fresh water for avoiding salt solution to cause resistance value instability, resistance to separate matter to the corrosion of equipment and because of salinity is inhomogeneous;
In order to regulate reactive load, set up the reactor that is connected with major loop;
Consider to bear the test needs of high-power generator,, pole plate is optimized design from increasing aspects such as pole plate number, increase pole plate area, adjustment polar plate spacing;
For guaranteeing the safe, steady, adjustable of device, key is further to improve load-bearing capacity and the worm gear case locking property and the stationarity of gearing, the vertical worm gear case that gearing adopts reducer casing and motor pedestal to be integrated is readjusted the design worm gear axial module and the worm gear number of teeth;
For guaranteeing water temperature and water evaporates maintenance balance in the load test process, keep the stable of load current with further arrival, water inlet pipe, overflow pipe and the bleeder pipe of forming water lines is optimized design;
Handling safety for assurance device; at electric major loop and control box thereof; take further innovative approach, as adopting bus-bar being connected, set up fault-phase protection and the indication of pole plate position and be provided with cable drum that stube cable uses and green indicating lamp etc. at control loop with contactor.
In sum, by the improvement of electrolyte, pole plate and gearing, the corrosion of pole plate is improved greatly especially, and overcome the problem that causes because of conductive capability and three-phase electricity laod unbalance etc.Reach that to operate steadily, regulate little, the load ability to bear of fluctuation big and have advantages such as one-piece construction is simple, cost is low, capacity is big.In force, generator load test one-time success rate improves, thereby has shortened the fuel consume cost of test period and reduction test period greatly.Also possess simultaneously deposit, transportation, easy to use, be fit to open-air the placement, can be at 120 meters apart from characteristics such as straighforward operations.
