Three-phase asynchronous motor phase of the situation
Branch fuse blown; 1,2 branch circuit conductors between the motor power connector is bad. Joint long-term heat oxidation, to further increase the contact resistance. The vicious cycle, eventually blown; 1.3 bad the motor terminal box joints, causing joint burned. 2 broken motor phase winding within a motor burned to understand the underlying reasons. Make a wish list of Table 1. Defects or damage to the electrical switch knife switch,[link widoczny dla zalogowanych], air switch and electrical switch contacts and other contacts of a bad or damaged phase. In addition to these reasons, I also plant many times burning occurred after stopping the motor accident. This is mainly due to the current market sales of exchanges and contacts of poor quality, most of the contact material undesirable. When used in larger capacity when the motor distribution. For current use (especially starting current) is large. Often caused by contact of a molten phase or two phases. When you press the stop button, although the loss of power contactor coil, core release, the main contact should all disconnected. But they can not be disconnected because of melting, in which case they can not all three-phase main contact for reliable contact, actually led to the motor phase operation. Eventually burn the motor accident. So. First of all, which requires one hand, we note that in the procurement of electrical components to good quality. The other hand, the operator press the stop button, pay attention to check, verify that left the scene only after stop,[link widoczny dla zalogowanych], he must immediately take measures to basket. If the site with air switch,[link widoczny dla zalogowanych], then quickly opened to: If the air switch is not on the scene, it should be restarted. Go off the air switch. Phase induction motor burned up and running is easy, it has attracted enough attention to the majority of users, and actively adopted various measures to prevent such incidents from occurring. Is worn out of the deepest concave to 3ram. Beijing by the use of new materials produced by the Tianshan \Meet requirements. Meet production needs. Has been in use for six months. We will be more widely used this technology to a deeper level. Such as. Putty to use corrosion-resistant, wear-resistant repair agent,[link widoczny dla zalogowanych], copper, aluminum, stainless steel repair agent and so on. New tools to make the repairs and make new contributions to the production salinization. 2. . One (China mineral salt) No. 6 of 1996 (total 130) three-phase asynchronous motor table of phase stator winding phase power shortage causes changes in the torque link means wear and tear changes in the torque of the motor power supply only conclusions of the stator care around the open phase will stop in time after treatment. Peng sting transformer rated negative in the normal group or they will burn the motor copper loss. Device operation under high load conditions should be used for the normal three-phase type (can not be used under low pressure off the two-phase run-time half-phase) with differential phase off the side of the temporary organization, IAB,[link widoczny dla zalogowanych], 2 times (such as JRI6 - t: :: ~ / 3D) thermal relay phase Ic will melt, or multi-function motor protection and other protective measures for the normal operation of wire melting reservoir. Off line that can not be started. Only hum. Times the line starts to burn strong electric motor is only rated a negative torque relative to the stator windings is broken and must stop in time handling. Machine set off as normal when the copper loss or the motor will burn the Ministry of the normal operation of a phase should be used with a differential phase-type phase around the open phase Ic = 1. 2 / 3 of run-time institutions (such as the JR16 - c :::~/ 3D set off 5IH 2 times type) or cooked multifunction relay line I = 1B = motor protection and other protection measures over Tibet. 86.6% IH generally can not start. Iac = I_ only very light load in the motor case. Possible start. 5IH ten power torque stator windings only general. After the page break phase time line will be j held in the normal group rated copper loss stopping treatment. Otherwise it will burn power failure. Run-time load off the normal machine. 58% of Citrus switch can be used to run two or three phase General Electric IA: 0 to 2 times the electrical heat worthy of protection for open phase. Defects | B = Ic can not start. Only hum. Strong start to burn or damage the motor line. Given a negative bad √ 3IH whip the stator windings when the motor torque only at light load (rated load and off load the whole pressure for the normal group, 58%) and off machines. Although the line current phase run-time (BC) phase IB, Ic does not exceed the rated current. However, = Ic = 58% of the copper loss for the whole pressure (Bc) Pat-phase current is set up to whip --/3IH normal operation current 116%; When the load is 460% or more line break phase, 1, c can be up to I = 2j footpath. Times 1.7 times. 2.8 times more copper loss; if the rated load off phase. The situation is more serious. Park this happens to stop in time handling break phase. Otherwise, the motor will be burned. Should be used with a differential phase-type body-off phase (such as JRI6 - c :::~/ 3D type) multi-function motor protection thermal relay or open-phase protection devices such as' can not start. Only hum. Start to burn the motor force.
