防爆電機(jī)鐵芯故障有幾種?其危害是什么?

防爆電機(jī)鐵芯的好與壞,對(duì)整臺(tái)防爆電機(jī)的質(zhì)量起著至關(guān)重要的作用。鐵芯質(zhì)量差,防爆電機(jī)的cos要降低;因鐵損耗增加,效率也要降低;因空載電流大,負(fù)載電流隨之增大,溫升也要升高;電磁噪聲要增加;毛刺大、疊壓不齊,對(duì)絕緣有直接損傷,是繞組故障的禍根。為了防止因鐵芯質(zhì)量差,絕緣易受損傷,制造廠不得不采取消極的措施--增加主絕緣厚度,浪費(fèi)材料,提高了防爆電機(jī)成本,散熱也差,而轉(zhuǎn)子鐵芯菱形還影響動(dòng)平衡的精度。這個(gè)是防爆電機(jī)鐵芯故障的危害。防爆電機(jī)鐵芯的故障,嚴(yán)格的講,指的是鐵芯制造質(zhì)量。它由毛刺大、疊壓不齊、裝壓不緊及變形四種類型構(gòu)成(圖\文brfr.com.cn/)。

Explosion proof motor iron core of good and bad, the whole sets of explosion-proof motor quality plays a crucial role in. The core of poor quality, explosion-proof motor COS to reduce; because the iron losses increase, efficiency to decrease; because of the no-load current, load current increases, the temperature rise can be increased; electromagnetic noise will increase; burr, laminated not neat, the insulation has direct damage, is the bane of winding fault. In order to prevent poor quality for core, insulated vulnerable to injury, factory had to take measures to increase negative -- main insulation thickness, material waste, improves the explosion-proof motor cost, heat is poor, and the rotor core diamond also affects the dynamic balance precision. This is the explosion-proof motor iron core fault hazard. Explosion proof motor iron core fault, strictly speaking, refers to the core manufacturing quality. It consists of burr, laminated not neat, loading is not pressed tightly and deformation of four types.
