Embodiment Construction

[0016] see Figure 1-2 In this embodiment, an exciter for sintering waste heat generation to prevent oil pollution, including a bearing housing 3, a main shaft 2 is installed in the bearing housing 3, one end of the main shaft 2 is connected to the generator set 1, and the other end is connected to the excitation unit, and the excitation unit is provided with a casing 4 , the top of the housing 4 is provided with an air inlet pipe 6, the side of the housing 4 is provided with an air outlet 5, the air inlet pipe 6 is equipped with a cooling fan 7, and the cooling fan 7 blows air into the housing 4 during operation so that the inside of the housing 4 is under positive pressure surroundings.

[0017] The height from the air inlet of the air inlet pipe 6 to the top of the housing 4 in this embodiment is 500mm (according to the actual situation, the air inlet should be higher than the oil mist distribution area 8 if it is greater than 300mm), and the cooling fan 7 is installed on t...

Abstract

The invention discloses a sintering waste heat power generation exciter and method for preventing oil contamination infection. The sintering waste heat power generation exciter comprises a bearing seat, a main shaft is arranged in the bearing seat, one end of the main shaft is connected with a generator set, the other end of the main shaft is connected with an exciter set, the exciter set is provided with a shell, an air inlet pipe is arranged at the top of the shell, an air outlet is formed in the side face of the shell, and a cooling fan is arranged in the air inlet pipe. When the cooling fan works, air is blown into the shell to form a positive pressure environment in the shell. According to the invention, the condition that the exciter unit is infected by oil stains is fundamentally avoided, and the harm caused by the reduction of electrical insulating is avoided.

Description

technical field [0001] The invention relates to the technical field of sintering waste heat power generation production, in particular to an exciter and method for preventing oil pollution from sintering waste heat power generation. Background technique [0002] The sinter waste heat power generation system is a secondary energy recovery system that collects sinter waste heat for power generation through a sinter ring cooler. Among them, the generator set is mainly composed of generators, exciters, bearing housings and other main components. Among the various protections of the generator, the rotor grounding protection is an indispensable link. When the rotor has a one-point grounding fault, although it will not cause direct harm to the generator itself in a short period of time, when the deterioration intensifies and two-point grounding Finally, it will seriously threaten the safety of the generator, such as: destroying the symmetry of the air gap magnetic field of the gen...
