Transformer Protector Transformer Fire Protection 

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", FMD 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.
Principle of Extinct Fire:
When the transformer is on fire, the fire detector is activated, the gas relay closes, and the electric breaker
Switches off. As a result, BPZM-MRD Nitrogen Injection system is operated and the oil drain valve opens to draw off oil.
Then nitrogen gas is continuously injected, the large amount nitrogen gas sufficiently cools down the
Transformer, extinguishes fire, and prevents any re-combustion.
Working Conditions:
1, Fire detector, drain valve, fire protection cabinet could be located outdoor. Control panel should be
Located indoor. Around the site there should be no violent vibration and shock, no corrosive gas.
2, Ambient Temperature
A) outdoor application: -40° C ~ 60° C
B) indoor application: 5° C ~ 30° C
3, Relative Humidity
A) outdoor application: ≤ 95 (@ 20° C± 5° C)
B) indoor application: ≤ 85 (@ 20° C± 5° C)
4, Power Source
Working power source: DC220V or DC110V
