Abstract

The invention discloses a water resistor for a load test in a generator. A feed water pump is arranged on an inlet pipe of each operating water tank to pump the water of a storage water tank into the operating water tank, and a draining pump is arranged on a water outlet pipe of each operating water tank to pump the water in the operating water tank to a spraying pipe. A water receiving basin capable of collecting sprayed water is arranged below the spraying pipe. Water return channels are formed at the bottom of the water receiving basin to return the collected water into the storage water tank. The operating water tanks are correspondingly connected with the feed water pumps and the draining pumps, and water levels in the operating water tanks can be regulated by regulating the flows of the feed water pumps and the draining pumps to further regulate a load. The water levels are changed uniformly and slowly, so that the load can be regulated and changed stably, and a sudden change is avoided. In addition, the water drained by the operating water tanks is sprayed and cooled, and then returns to the storage water tank, heat produced by the power consumption of the generator in the load test in the circulation process of the water can be timely dissipated to the outside, and the water in the operating water tanks cannot be gasified in the test process, so that the stability of the load can be maintained.

Description

technical field

[0001] The invention relates to a water resistance used in the load test of a generator in the shipbuilding industry, and a generator load test device. Background technique

[0002] At present, there are two main ways to control the load up and down of the water resistance of the generator load test device used by the shipyard, one is the dynamic pole control, and the other is the air pressure control. Among them, the moving pole control means that the hoist drives the pole plate to move up and down in the load cylinder to change the contact area between the pole plate and the water, so as to realize the load lifting, so as to provide different load conditions for the generator to test. It is a mechanical control, which is restricted by the control method. During the load adjustment process, the load fluctuates greatly. Pneumatic control is to change the air pressure of the container connected with the load cylinder, change the amount of water pressed from ...
