Problems solved by technology

[0003] However, in the actual operation process, due to the large indoor space of the bridge arm reactor, the air volume that can effectively exchange heat with the bridge arm reactor with the largest heat generation only accounts for a small part of the total ventilation volume, and most of the forced exhaust air volume consumes In order to reduce the ambient temperature, instead of directly reducing the temperature of the equipment, and the wind pressure of the forced mechanical exhaust fan is not enough to overcome the flow resistance, resulting in a reduction in the natural air intake, the actual ventilation value does not meet the design requirements, and hot air accumulates It cannot be discharged smoothly in the dead angle of air flow, resulting in the indoor ambient temperature of the bridge arm reactor being higher than the design temperature, which is not conducive to the normal operation and daily maintenance of the equipment
In addition, the natural air intake from the wall louvers is a negative pressure air intake, which can easily bring dust from the outside into the room. It is difficult to keep the indoor environment clean only by the 5-layer filter installed behind the louvers.

Abstract

The invention relates to a downside air supply mechanical ventilation system of a bridge arm electric reactor chamber and a construction method thereof. The ventilation system comprises an air supply device, an underground air supply channel and a plurality of exhaust devices. The air supply device is arranged outside the bridge arm electric reactor chamber. An air supply outlet of the air supply device is communicated with the inlet end of the underground air supply channel through a pipeline. The underground air supply channel is located under the ground of the bridge arm electric reactor chamber. The underground air supply channel is provided with a plurality of air outlets, and each air outlet is arranged under a bridge arm electric reactor. The exhaust devices are arranged on a roof of the bridge arm electric reactor chamber, and one exhaust device is arranged over each bridge arm electric reactor. The number of the air outlets of the underground air supply channel and the number of the exhaust devices are consistent with the number of the bridge arm electric reactors in the bridge arm electric reactor chamber. The downside air supply mechanical ventilation system of the bridge arm electric reactor chamber and the construction method thereof can effectively solve the equipment operation problem, improve radiating efficiency and be widely applied to the technical field of large-scale equipment radiating in a transformer substation.

Description

Technical field [0001] The invention relates to a substation building ventilation system and a construction method thereof, in particular to a mechanical ventilation system and construction of a bridge arm reactor room suitable for heat dissipation of large equipment in a flexible DC converter station or similar occasions method. Background technique [0002] Flexible DC transmission technology is a new type of power transmission technology based on voltage source converters, self-shutdown devices and pulse width modulation (PWM) technology. This power transmission technology can supply power to passive networks without commutation failure , There is no need for communication between converter stations and it is easy to form a multi-terminal DC system. The bridge arm reactor used in the flexible DC converter station generates a very large amount of heat. It mainly relies on the natural intake of the wall shutters, the forced mechanical exhaust of the roof fan or the side wall fa...
