Often subject to not hot. (4) a large squirrel cage rotor surface stray loss, high temperature insulation as to not endanger the neighbors is limited. Can pre-paint brush to estimate irreversible. Troubleshooting of electrical heat 6 when the motor temperature exceeds the maximum operating temperature or temperature exceeds the set temperature, while not exceeding the prescribed or, but a sudden temperature rise in the low load increases, indicating that the motor is faulty, the judge and troubleshooting are: (1) temperature rise at rated load temperature rise does not exceed the limit, only the ambient temperature exceeds 40 ~ C, most people leaving the motor temperature exceeds allowable working temperature. This phenomenon indicates that the motor itself is normal. The solution is to use artificial methods to decrease in temperature, such as can not, you must reduce the load operation. (2) temperature rise at rated load beyond nameplate requirements. Whatever the case,[link widoczny dla zalogowanych], are the motor is faulty, you must stop to check, especially for the temperature rise abruptly more to note. The external factors are: the grid voltage is too low or line voltage drop is too large (more than l0%), the load is too heavy (more than l0%), electrical and mechanical mismatch; internal reasons are: single-phase operation,[link widoczny dla zalogowanych], inter-turn short circuit, short circuit between phases , stator ground, or damage to tighten the fan, air duct obstruction, bearing damage, rub-phase stator and rotor, motor and cable connector fever (especially copper and aluminum or aluminum aluminum connection), such as the motor of corrosion or moisture. In addition, the motor may be reversing in theory, but some of the fan motor directional, such as anti-, and temperature rise would exceed many. In short, the situation must be for specific, troubleshooting. (Received date: 2001 A O1-06) National Power Corporation and Transmission Operations Department,[link widoczny dla zalogowanych], specifically the Chinese Society of Electrical Engineering Safety Committee and the China Electric Power Press, 2001 l0 23 ~ 25, jointly held in Xiamen, 2001 \Director of State Power and Transmission Department of Zhou Jian spoke at the meeting. He fully affirmed the safe production of electricity and two periodicals the positive role played by and for the current grim situation of safe production in the next phase of the two focus s made specific requests to the company system and transmission units to seriously implement the Ministry of State Power Journal subscriptions in 2002 to do the work of the two to the order, the group asked him do a good job and two periodicals and distribution, study and work and play its due role in the two s efforts to improve workplace safety. At the meeting, Guodiangongsi security experts spoke on behalf of the two Journal editorial summary of the work were made in 2001, presented their 2002 work plan and direction, some provinces do companies soliciting contributions on behalf of exchange and distribution of work experience and experience, Qingdao Bureau, Shaoxing Office also were made by \After a serious and heated discussion, participants agreed that: power security technology)) to improve the safety level of electricity production to make a positive contribution, while the communications network is \, due to the tireless efforts of the majority of liaison, communication network in the success of the \Class of security seminars, exchange of intelligence issued last played, the role of lower levels on the up. Liaison to the General Assembly to provide our strong sense of ownership, in accordance with instructions of the leadership Guodiangongsi requirements, make persistent efforts, the actual production of the unit, to forge ahead and further improve the publication of the work of the unit, hoping to further improve the editorial work enhance the sense of service for the whole industry, facing a new situation in the power system, stand on a whole new level understanding of their work to focus on front-line employees serve around the new situation and new situations and new problems,[link widoczny dla zalogowanych], from the Columns , content topics, and enhance readability and so hard, asked him to do group work, in time, sum up experiences and practices to promote some of the advanced,[link widoczny dla zalogowanych], making publications more responsive to the situation of power development, safety education more in line with the needs of frontline workers . The Assembly also commended the work of the advanced communications network in 2001 units, issue collective work of art, communication net work of activists and writers active molecules (see the list of this issue).
