Causes and monitoring of generator set fire

Some friends do not choose the right equipment in the selection of Today, Haixing is going to talk to you about the reasons for the generator set fire.generator sets , or have minor shortcomings in operation, or lack of daily maintenance, which will pose safety hazards to the generator set.

(1) Overload generator sets will be overloaded, too low voltage, and excessive iron loss of three-phase asynchronous generator sets.
(2) Short circuit generator sets are divided into inter-turn short circuit, inter-phase short circuit and ground short circuit.
(3) If the contact points or lead wire contacts of the poor contact coil are loose, the contact resistance will increase.
(4) Improper selection of generator sets of different protective forms should be selected in different places, otherwise a fire will occur.
(V) Single-phase operation three-phase asynchronous generator set continues to operate when one phase is not powered on, and then the other two phases will flow through a single-phase current. This state is called single-phase operation.
(VI) There is friction during the rotation of the mechanical friction generator set, and friction will increase the temperature of the generator set.
(7) Poor grounding device When a generator set short circuit to the ground occurs, if there is no reliable grounding protection, the housing will be energized.

In daily use, we must strengthen the monitoring and maintenance of power generation. The operating status of the generator set can be expressed in terms of the magnitude of the line current, the rise and fall of the voltage, the temperature rise, and the difference in sound. Generally speaking, the current, voltage and temperature rise of the generator set must not exceed the allowable value, otherwise the load should be controlled. Once abnormalities are found, they should be dealt with in a timely manner.
