Explosion-Proof Type Of Explosion-Proof Battery Electric Locomotive

Explosion-proof electric locomotive is a type of motor that can be used in flammable and explosive plants, and does not generate electric sparks during operation. Explosion-proof electric locomotives are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In order to let everyone know more about the equipment, today we mainly come to know what are the explosion-proof types of explosion-proof battery electric locomotives?

(1) Flameproof "d"
All parts of the equipment that may ignite explosive gas mixtures are enclosed in a shell, and its shell can withstand any flammable mixture that penetrates into the shell through any joint surface or structural gap of the shell. Ignition of an explosive environment formed by one or more gases or vapors.

(2) Increased safety type "e"
It is an explosion-proof type that takes some additional measures to increase the safety of electrical equipment that does not generate arcs and sparks under normal operating conditions, and prevents the possibility of dangerous temperatures, arcs, and sparks on its internal and external components.

(3) Intrinsically safe "i"
All electrical circuits inside the equipment are intrinsically safe circuits that cannot ignite the specified explosive gas environment under the conditions specified in the standard (including normal operation and specified fault conditions), any electric sparks or any thermal effects.

(4) Positive pressure type "p"
It is a kind of electrical equipment that achieves safety by keeping the pressure of the protective gas inside the equipment casing higher than the pressure of the surrounding explosive environment.

(5) Oil-immersed "o"
Immerse the entire equipment or its components in oil (protective fluid) so that it cannot be exposed to explosive gas environments above the fuel surface or outside the enclosure. This is an old method of explosion-proof technology mainly used in switchgear.
