The remarkable point is that ordinary distribution boxes can only be used in non explosive environments. Explosion proof distribution boxes can be used in different explosive environments according to different explosion-proof types! Moreover, the explosion-proof distribution box is an explosion-proof electrical product that has passed the explosion-proof certification of a qualified third-party inspection organization.

在形状上，普通配电箱为铁制的，而防爆配电箱为铸造或钢板焊接后加工而成，具有较高的强度。

In terms of shape, the ordinary distribution box is made of iron, while the explosion-proof distribution box is processed after casting or steel plate welding, which has high strength.

在结构上，普通配电箱内元器件，可以排列在一起，布线方便，而防爆配电箱内部分为若干个单元，每个开关、电器元件都要隔离。

Structurally, the components in the ordinary distribution box can be arranged together for convenient wiring, while the explosion-proof distribution box is divided into several units, and each switch and electrical components shall be isolated.

在密封上，普通配电箱对密封要求不很严格，防爆配电箱盖子与箱体密封较好，并经过严格检验合格后，由专门机构签发合格证明，并予以出厂销售。

In terms of sealing, ordinary distribution boxes do not have strict sealing requirements. The cover and box of explosion-proof distribution box are well sealed. After passing the strict inspection, the certificate of conformity shall be issued by the special organization and sold out of the factory.

在应用上，普通配电箱一般应用于民用和没有防爆要求的场所。防爆配电箱主要用于危险性可燃气体场所及爆炸性场所。

In application, ordinary distribution box is generally used in civil and places without explosion-proof requirements. Explosion proof distribution box is mainly used in dangerous combustible gas places and explosive places.

在上，普通配电箱便宜。防爆配电箱昂贵，一般是普通配电箱数倍。

In terms of price, ordinary distribution box is cheap. Explosion proof distribution box is expensive, which is generally several times the price of ordinary distribution box.

在安装上：防爆配线箱所有的电器元件都是装在箱体中，通过操作机构引到面板上进行操作，需要通过手柄操作开关，面板上的信号灯和开关是防爆元件可以暴露在空气中。

Installation: all electrical components of the explosion-proof distribution box are installed in the box and led to the panel through the operating mechanism for operation. It is necessary to operate the switch through the handle. The signal lamp and switch on the panel are explosion-proof components and can be exposed to the air.

防爆配电箱：

The explosion-proof distribution box:

防爆配电箱具有防爆性能的一类配电箱。主要有防爆照明配电箱、防爆动力配电箱、防爆防腐配电箱等。防爆配电箱适用于石化装置、石油平台、化工行业、制药行业、煤炭行业、冶炼行业、船舶制造、军工行业、纺织行业等易燃易爆场所。

Explosion proof distribution box is a kind of distribution box with explosion-proof performance. It mainly includes explosion-proof lighting distribution box, explosion-proof power distribution box, explosion-proof anti-corrosion distribution box, etc. Explosion proof distribution box is applicable to flammable and explosive places such as petrochemical devices, petroleum platforms, chemical industry, pharmaceutical industry, coal industry, smelting industry, shipbuilding, military industry, textile industry and so on.

使用方法：

usage method:

根据工作现场的实际照明需要，确定灯具的安装位置和方式，然后按灯具到220V电源接点的距离备好相应长度的三芯电缆线(如采用钢管布线则将三芯电缆线引入钢管灯具安装处)。

According to the actual lighting needs of the work site, determine the installation position and mode of the lamps, and then prepare three core cables of corresponding length according to the distance from the lamps to the 220V power supply contact (if steel pipe wiring is adopted, lead the three core cables into the steel pipe to the installation place of the lamps).

先卸下接线腔上的固定螺钉，拔出接线盒的接线部分；从包装盒内取出密封圈和接头(带紧定螺钉)，依次套入电缆；然后将三芯电缆线的一端分别接入盒内的标识“L”、“N”和接地处，用压线卡压紧电缆后，并用紧固螺钉固定好，然后拧紧接头，压紧密封圈，并从侧面拧紧紧定螺钉。

First remove the fixing screw on the wiring chamber and pull out the wiring part of the junction box; Take out the sealing ring and connector (with set screw) from the packaging box and put them into the cable in turn; Then connect one end of the three core cable into the identification "L", "n" and grounding point in the box respectively, press the cable with the wire clamp, fix it with the fastening screw, then tighten the joint, press the sealing ring, and tighten the fastening screw from the side.

将第2步的部件旋入钢管，从侧面装上紧定螺钉锁紧，再将灯体沿接线盒的导轨装入，然后拧紧面板上的螺钉。

Screw the components in step 2 into the steel pipe, install the set screw from the side and lock it, then install the lamp body along the guide rail of the junction box, and then tighten the screws on the panel.

把三芯电缆线的另一端按防爆配电箱要求接通220V电源。

Connect the other end of the three core cable to the 220V power supply according to the requirements of the explosion-proof distribution box.

更换灯泡时，先切断电源，然后用内六角扳手卸下壳体上的紧定螺钉，用大螺丝刀或其它工具旋松灯盖6圈，再用手小心将灯盖缓慢卸下，旋下旧灯泡换上新灯泡。

When replacing the bulb, first cut off the power supply, then remove the set screw on the shell with an Allen wrench, loosen the lamp cover by 6 turns with a large screwdriver or other tools, and then carefully remove the lamp cover by hand, unscrew the old bulb and replace it with a new bulb.
