Open-type, breeze-circulating positive-pressure device

It is primarily used for the protection of enclosed busbars in generator sets. The device comprises three main components: an on-site instrument‑air compressor, an air storage tank, and a control cabinet. The compressor and the storage tank are integrated into a single unit, while all other parts are assembled within the control cabinet, facilitating installation and operation. After compressing, drying, and filtering the compressed air, the system injects it into the enclosed busbar, maintaining a slight positive pressure inside. This prevents external air containing moisture and impurities from entering the busbar, thereby completely eliminating abnormal phenomena such as insulation degradation and flashover, and ensuring the normal startup and reliable operation of the generator set.

Dual-Source Positive-Pressure Forced-Air Intelligent Protective Device

New Products / New Technology

The dual‑gas‑source positive‑pressure forced‑air intelligent protection device combines the functions of conventional micro‑positive pressure systems with an advanced high‑flow, high‑pressure, high‑velocity forced‑air system. It enables rapid air exchange within busbars in a shorter time, providing enhanced protection for enclosed busbar systems. Equipped with a built-in pressure‑sensing system, it continuously monitors the busbar's sealing integrity and dynamically adjusts air pressure to deliver proactive defense. Operating continuously 24/7, it features low energy consumption, long service life, and reduced maintenance costs. The forced‑air positive pressure creates a dynamic air barrier, eliminating reliance on busbar sealing performance. It supports seamless switching between compressed air and ambient atmospheric air in just 0.5 seconds, adapting to complex operating conditions and ensuring sustained, stable operation.
