Ventilating system of locomotive electrical chamber with external corridor

Abstract

The invention provides a ventilating system of a locomotive electrical chamber with an external corridor. The ventilating system mainly comprises an air using cavity (F), an air collecting cavity (H), a resistance braking device air inlet filter screen assembly (9) and a resistance braking device air outlet shutter assembly (7), wherein the air collecting cavity (H) consists of a filter screen assembly (1), a controllable shutter assembly (2), the upper part of a side wall I (3), the upper part of a side wall II (10), an S-type filter screen assembly (5), a ceiling I (6) and an air collecting cavity air channel (13); the air collecting cavity (H) is positioned at the top of a locomotive; and the resistance braking device air inlet filter screen assembly (9) and the resistance braking device air outlet shutter assembly (7) are respectively arranged at the air inlet end and the air outlet end of a resistance braking device (E). The ventilating system realizes centralization of a locomotive air inlet system, and also provides air for circulating cooling and ventilation outlet protection for the resistance braking device (E), so that safety in working of the resistance braking device is ensured.

Description

technical field [0001] The invention relates to the field of locomotive equipment, in particular to a ventilation system for an electrical room of an outer corridor locomotive. Background technique [0002] The ventilation system of the locomotive electrical room in the traditional outer corridor is designed on the side wall door of the locomotive, and the cooling air for the main generator, traction motor and other electrical equipment is obtained from the scattered side wall doors, which cannot realize the centralized function of the ventilation and air intake system ; At the same time, resistance braking is a kind of electric braking method of locomotives. It uses the reversible principle of DC motor. When braking, the DC motor is changed to DC generator operation, and the kinetic energy of the train is converted into electric energy. On the brake resistor, it is released into the atmosphere in the form of heat energy. Therefore, a corresponding ventilation system is also...

Problems solved by technology

[0002] The ventilation system of the locomotive electrical room in the traditional outer corridor is designed on the side wall door of the locomotive, and the cooling air for the main generator, traction motor and other electrical equipment is obtained from the scattered side wall doors, which cannot realize the centralized function of the ventilation and air intake system ; At the same time, resistance braking is a kind of electric braking method of locomotives. It uses the reversible principle of DC motor. When braking, the DC motor is changed to DC generator operation, and the kinetic energy of the train is converted into electric energy. On the braking resistor, it is dissipated into the atmosphere in the form of heat energy. Therefore, a corresponding ventilation system is also required to match it for heat dissipation, so as to ensure the safe operation of the resistor braking device.

However, there is no resistance braking device in the electrical room of the locomotive in the traditional outer corridor, so there is no corresponding resistance braking air in and out ventilation system
