Talking about the characteristics of explosion-proof lighting distribution box
Explosion-proof distribution box is a kind of distribution box with explosion-proof performance. It mainly has explosion-proof lighting distribution box, explosion-proof power distribution box, explosion-proof anti-corrosion distribution box, etc. It is mainly used in petrochemical plants, oil platforms, gas stations, Lighting in flammable and explosive places such as oil pumping stations and transfer stations. Explosive gas environment in Zone 1 and Zone 2. Combustible dust environment in Zones 21 and 22.
The "distribution box" is a circuit distribution box for all users to use electricity. The distribution box is assembled according to the requirements of electrical wiring. The switchgear, measuring instrument, protective appliance and auxiliary equipment are assembled in a closed or semi-closed metal cabinet or on the screen to form a low-voltage power distribution device. The circuit can be switched on or off with a manual or automatic switch during normal operation. In the event of malfunction or abnormal operation, the circuit or alarm is cut off by means of a protective device. The measuring instrument can display various parameters during operation, and can also adjust some electrical parameters to prompt or signal the deviation from the normal working state. Commonly used in various hair, distribution, and substation.
Advantages of the distribution box: easy to manage. Its main purpose is to distribute electrical energy reasonably, which facilitates the opening and closing of the circuit. It has a high level of security protection and can intuitively display the conduction state of the circuit. It is helpful for maintenance when a circuit failure occurs.
Explosion-proof lighting distribution box features:
1. The structure of the explosion-proof lighting distribution box is an explosion-proof structure, the shell is welded by steel plates, and the surface of the casing is electrostatically sprayed;
Second, the explosion-proof lighting distribution box contains high-breaking miniature circuit breaker or molded case circuit breaker, AC vacuum contactor, motor protector, voltmeter and other components, with overload, short circuit, under voltage, phase loss, leakage and other protection functions, also Some other components can be installed according to customer requirements;
Third, BXM (D) 59-series explosion-proof distribution box in and out of the line are using non-sparking explosion-proof plug-in device, and there is a clear equipment number indicator board, the indicator board is formed by 304 stainless steel plate bending, polishing, beautiful appearance It is generous and practical, and it is also convenient to find the faulty components or lines when the line is in trouble, and repair it as soon as possible;
Fourth, the explosion-proof surface uses a different production technology from the explosion-proof distribution box, and adds a “0†ring to make the cabinet protection level IP65, which solves the problem of using the rainwater in the traditional explosion-proof box to ensure the explosion-proof When the electric box is in the closed state, it will not enter the water and cause a short circuit;
5. All fasteners are made of 304 stainless steel fasteners which are resistant to strong corrosion, so as to avoid rusting of the firmware, the explosion-proof distribution box can not have good explosion-proof capability.
