High Voltage Oil Immersed Transformer Nitrogen Injection and Oil Evacuation System

Overview BPZM-MRD Nitrogen Injection Explosion Prevention & Fire Protection System became more advanced fire protection and explosion prevention system for the Oil immersed transformer protection after "Water Spray System" and "CO2 Spray System", BPZM-MRD Systems were also examined by "National Fixed Fire Extinguishing Systems and Components Quality Supervision and Inspection Center" and passed the test as qualified. Transformer are among the most expensive equipment located in power plants and substations. They generally contain a large quantity of combustible substance, which can spray fire to nearby installations and caused a power failure and huge economic losses. Special attention should therefore be paid to their protection. The traditional protection of transformer usually focuses on the electric parameters of the transformer, while the sudden pressure increased within the tank resulting from insulation breakdown does not draw much attention.

Function Explosion Prevention and Fire Extinguishing The system can extinguishing the fire immediately thro injected the N2 gas into the Transformer Tank. The Nitrogen can be injected continuously for 30 mins to stir and cool down the transformer oil, which also isolated the air from the tank.

Specification Please specify the following details when ordering 1. layout drawing, contact details of transformer manufacturer and system designing company. 2. if any special requirement, please indicate.

Scope of applications Generator power unceasingly increase with the development of technology, there are many transformer explosion happened due to ineffective of current breaker between the Generator and Power Transformer. BPZM-MRD Nitrogen Injection System is suitable for new or remodeled power transformer which located in the high power plant, substations, indoor substations, underground substations, city substations and cold and water-deficient area.
