日常設(shè)備使用中有不少因素可能對(duì)配電箱性能產(chǎn)生影響，比如日常的維護(hù)措施是否科學(xué)合理，空氣中的灰塵，使用環(huán)境的溫度，散熱是否良好以及設(shè)備自身的震動(dòng)等都有可能影響設(shè)備性能，影響仿威圖機(jī)柜性能的主要因素。
There are many factors in the daily use of equipment may affect the performance of the distribution box, such as whether the daily maintenance measures are scientific and reasonable, dust in the air, the temperature of the use environment, heat dissipation is good and the vibration of the equipment itself may affect the performance of the equipment, the main factors affecting the performance of the imitation Weichart cabinet.
按國(guó)標(biāo)設(shè)計(jì)和制造的電氣成套設(shè)備運(yùn)行時(shí)周圍環(huán)境溫度的上限值不應(yīng)超過40℃，而盛夏暴露在烈日中的戶外配電柜，由于太陽(yáng)光的直射、水泥地面熱量的反射以及柜內(nèi)設(shè)備自身產(chǎn)生的熱量，有時(shí)戶外配電柜內(nèi)的溫度竟超過60℃。
The upper limit of ambient temperature of complete electrical equipment designed and manufactured according to national standards should not exceed 40℃ when it is running. However, the outdoor power distribution cabinet exposed in the hot sun in summer sometimes has a temperature of more than 60℃ due to direct sunlight, heat reflection from the cement floor and heat generated by the equipment in the cabinet.
電器觸頭因溫度過高而增加接觸電阻，接觸電阻增加又加劇發(fā)熱，如此惡性循環(huán)終導(dǎo)致觸頭燒壞；同時(shí)溫度過高還會(huì)影響戶外配電柜保護(hù)性能的穩(wěn)定性、動(dòng)作的可靠性、計(jì)量的準(zhǔn)確性。
The electrical contact increases the contact resistance due to high temperature, and the increase of contact resistance increases the heating, so the vicious cycle eventually leads to the contact burn out; At the same time, the high temperature will affect the stability of outdoor PDC protection performance, reliability of operation, and accuracy of measurement.
設(shè)備的防塵：防塵是這類設(shè)備使用過程中須要注意的事項(xiàng)，機(jī)箱長(zhǎng)時(shí)間積聚灰塵會(huì)大大降低散熱功能，導(dǎo)致風(fēng)扇等部件無(wú)法正常運(yùn)轉(zhuǎn)，從而產(chǎn)生一定的噪音。因此除了在設(shè)備使用中采取一定的防塵措施外，對(duì)于設(shè)備機(jī)箱的日常清理也是比較重要的。
Dust prevention: Pay attention to dust prevention when using the device. Dust accumulation in a shelf for a long time greatly reduces the heat dissipation function and causes the abnormal operation of components such as fans, which causes certain noise. Therefore, in addition to taking certain dust-proof measures in the use of the device, it is also important to clean the device chassis daily.
設(shè)備的散熱情況：配電箱是否能夠正常運(yùn)行，與設(shè)備的散熱情況有較為直接的影響。如果散熱情況較差可能導(dǎo)致設(shè)備癱瘓無(wú)法正常運(yùn)行。
Heat dissipation of the device: The normal operation of the power distribution box directly affects the heat dissipation of the device. If the heat dissipation is poor, the device may break down and cannot run normally.
設(shè)備產(chǎn)生的振動(dòng)噪音：設(shè)備運(yùn)行中出現(xiàn)的噪音主要是由于機(jī)箱的硬度及箱體的連接方式的不同導(dǎo)致的。如果材料較薄，導(dǎo)致機(jī)箱不堅(jiān)固，在使用中與內(nèi)置的電子設(shè)備形成共振產(chǎn)生噪音。
Vibration noise generated by the equipment: The noise generated during the operation of the equipment is mainly caused by the hardness of the box and the connection mode of the box. If the material is thin, the chassis is not solid, in use with the built-in electronic equipment to generate resonance noise.
還可能導(dǎo)致機(jī)箱變形使板卡死在上面。板材過于輕薄的機(jī)箱機(jī)柜強(qiáng)度不足，容易變形，進(jìn)而損傷硬件，同時(shí)由于其他零部件的共振出現(xiàn)噪音，造成配電箱的性能受到影響。
In addition, the chassis may be deformed and the board may be stuck on it. The chassis with too thin plates is weak in strength and prone to deformation, which damages the hardware. At the same time, the performance of the distribution box is affected due to the resonance noise of other parts.
