Abstract

The invention relates to a motor replacement device of a valve outer air cooling system. The motor replacement device is characterized by comprising a manual lifting platform (5), wherein; a universal wheel (6) is arranged at the bottom of the manual lifting platform (5); at least two positioning frames (4) are arranged on the top of the manual lifting platform (5); each positioning frame (4) is provided with an adjusting screw rod (1); one end of each adjusting screw rod (1) is provided with a rotating handle, and the other end of the adjusting screw rod (1) penetrates through the positioning frame (4) to be connected with a motor fixed clamping sleeve (2); the adjusting screw rods (1) and the positioning frames (4) are in threaded connection. The motor replacement device disclosed by the invention solves can be used for solving the problem of field motor replacement, eliminatinges the equipment hidden danger and bringings the safety benefit; the motor replacement device disclosed by the invention proves that only 1.6 hours are needed to replace one air blower by being tried in the field, thereby greatly reducing the motor replacement time; the motor replacement device can ensure the safe and stable operation of a direct-current system and can be used for replacing the abnormal motor in time.

Description

technical field [0001] The invention relates to a motor replacement device for an external air cooling system. Background technique [0002] At present, the converter station in the power system uses an external air cooling system to cool the internal cooling water to ensure that the converter valve works within an appropriate temperature range. For example, a converter station is equipped with a total of 24 fans per pole. According to statistics, from 09:00 to 17:30 in the summer of 2011 to 2012, all 24 fans of each set of external air cooling system were started. Due to the continuous operation of the motor for a long time, coupled with its harsh outdoor conditions, its abnormal rate is high. If the motor fails to stop running, the cooling capacity of the valve cooling system will be reduced, or if it takes too long to replace the faulty motor, the inlet valve temperature of the converter valve will continue to rise, causing the DC system to reduce power, or even block t...
