普通配電箱和防爆配電箱有哪些區(qū)別?

發(fā)布時(shí)間:2021-09-29 來源:http://j1bl.cn/ 瀏覽量:

顯著的一點(diǎn)就是普通配電箱只能用于非爆炸性環(huán)境,防爆配電箱根據(jù)防爆型式不同,可用于不同的爆炸性環(huán)境!不僅如此防爆配電箱是通過有資質(zhì)的第三方檢驗(yàn)機(jī)構(gòu)防爆認(rèn)證的防爆電氣產(chǎn)品。
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.
在形狀上,普通配電箱為鐵制的,而防爆配電箱為鑄造或鋼板焊接后加工而成,具有較高的強(qiáng)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.
在結(jié)構(gòu)上,普通配電箱內(nèi)元器件,可以排列在一起,布線方便,而防爆配電箱內(nèi)部分為若干個(gè)單元,每個(gè)開關(guān)、電器元件都要隔離。
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,普通配電箱對(duì)密封要求不很嚴(yán)格,防爆配電箱蓋子與箱體密封較好,并經(jīng)過嚴(yán)格檢驗(yàn)合格后,由專門機(jī)構(gòu)簽發(fā)合格證明,并予以出廠銷售。
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.
在應(yīng)用上,普通配電箱一般應(yīng)用于民用和沒有防爆要求的場(chǎng)所。防爆配電箱主要用于危險(xiǎn)性可燃?xì)怏w場(chǎng)所及爆炸性場(chǎng)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,普通配電箱便宜。防爆配電箱昂貴,一般是普通配電箱數(shù)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.
在安裝上:防爆配線箱所有的電器元件都是裝在箱體中,通過操作機(jī)構(gòu)引到面板上進(jìn)行操作,需要通過手柄操作開關(guān),面板上的信號(hào)燈和開關(guān)是防爆元件可以暴露在空氣中。
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.
防爆配電箱:
The explosion-proof distribution box:
防爆配電箱具有防爆性能的一類配電箱。主要有防爆照明配電箱、防爆動(dòng)力配電箱、防爆防腐配電箱等。防爆配電箱適用于石化裝置、石油平臺(tái)、化工行業(yè)、制藥行業(yè)、煤炭行業(yè)、冶煉行業(yè)、船舶制造、軍工行業(yè)、紡織行業(yè)等易燃易爆場(chǎng)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:
根據(jù)工作現(xiàn)場(chǎng)的實(shí)際照明需要,確定燈具的安裝位置和方式,然后按燈具到220V電源接點(diǎn)的距離備好相應(yīng)長度的三芯電纜線(如采用鋼管布線則將三芯電纜線引入鋼管燈具安裝處)。
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).
先卸下接線腔上的固定螺釘,拔出接線盒的接線部分;從包裝盒內(nèi)取出密封圈和接頭(帶緊定螺釘),依次套入電纜;然后將三芯電纜線的一端分別接入盒內(nèi)的標(biāo)識(shí)“L”、“N”和接地處,用壓線卡壓緊電纜后,并用緊固螺釘固定好,然后擰緊接頭,壓緊密封圈,并從側(cè)面擰緊緊定螺釘。
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.
將第2步的部件旋入鋼管,從側(cè)面裝上緊定螺釘鎖緊,再將燈體沿接線盒的導(dǎo)軌裝入,然后擰緊面板上的螺釘。
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.
把三芯電纜線的另一端按防爆配電箱要求接通220V電源。
Connect the other end of the three core cable to the 220V power supply according to the requirements of the explosion-proof distribution box.
更換燈泡時(shí),先切斷電源,然后用內(nèi)六角扳手卸下殼體上的緊定螺釘,用大螺絲刀或其它工具旋松燈蓋6圈,再用手小心將燈蓋緩慢卸下,旋下舊燈泡換上新燈泡。
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.
