1. There are three ways to query before and after the power failure.
1. Call 95598 power service hotline and operate according to voice prompts.
2. Search the website of the region (State Grid), Click [service and support], [power service], [power outage announcement] - fill in [region] - [start and end time], fill in [power outage range], and click [query]
3. The ways to view power outage information by wechat are as follows:
1. Open wechat and pay attention to the local state grid power company
2. Click to enter official account. If there is no binding user, you can bind the user, point my electricity, and then click the number of the house.
3. To view the power failure information, click public information, and then click power failure information
4. official account will send you a message, click to view;
5. Finally, you can see the power failure information. If the area is not right, you can choose the right area.
note:
if the area is often power failure, it is recommended to buy a generator set for standby. For the family, gasoline generator is OK. If the power of the family is more than 10kW, diesel generator is more cost-effective, and the generator set is noisy, Can choose silent diesel generator is good, gasoline generator sound is smaller, basically do not use a quiet box
for the standby power generator set used by enterprises, it's good to choose diesel generator. It can be used, silent diesel generator set, or automatic diesel generator set. Automation can be started automatically. When the power supply stops, the diesel generator set can be started automatically, which is very convenient.

2. OK. It's not as complicated as you think
3. Common faults and troubleshooting of ball mill
pitting corrosion or melting phenomenon of main bearing e to high temperature may be caused by one of the following reasons:
interruption of lubricating oil or insufficient oil quantity. In case of oil interruption, stop feeding water supply immediately, open the observation hole cover on the bearing, try to approach the hollow journal by hand (pay attention to prevent handle scalding) and check the bearing temperature. If the bearing is not overheated, it can be stopped to deal with the oil circuit fault; If the temperature of the bearing is quite high and the hand is close to the hollow journal and feels hot and smoking, do not stop the machine. Manually pour oil on the bearing to cool it until the temperature of the bearing returns to normal. If the engine is stopped without cooling measures, not only the bearing will not be burned out, but also the hollow shaft and big bearing will lock up
if the lubricating oil is too thick or too thin, it can be eliminated by re selecting the type of lubricating oil; Stop using cooling water or resistance heating
if the oil deteriorates, clean the bearing and oil passing parts and replace the lubricating oil
if the grinding and scraping of the big tile does not meet the requirements, the big tile should be re grinded and scraped to make it meet the technical requirements
impurities such as mineral sand and iron chips fall into the bearing surface, causing damage to the bearing surface and causing marks and grooves on the bearing surface
elimination method: clean the bearing, repair the bearing and journal, if the melting area is large, weld the bearing with welding gun or cast Babbitt alloy again, and change the lubricating oil
there is water in the lubricating oil, which can prevent the formation of oil film and proce cracks and pitting corrosion at local points without oil film
elimination method: clean the bearing and change the lubricating oil
it is difficult to start the mill, the starting current of the motor is large, and there is overload.
causes and elimination methods:
the medium in the mill agglomerates with the ore, and the center of gravity deviates from one side of the cylinder seriously. In this case, when driving the mill, the motor is not enough to overcome the eccentric moment, and cannot drive the mill, resulting in overload
elimination method: open the hole cover, enter the cylinder, turn the medium with a crowbar, and unload part of the medium
the unbalanced three-phase load of motor mainly refers to the unbalanced three-phase current of motor. The rotor of the motor is driven by the electromagnetic torque (i.e. rotating magnetic field) generated by the three-phase power supply passing through the stator winding. When the three-phase current through the stator winding is balanced, the electromagnetic torque generated is also balanced. If a certain phase current is caused by poor contact of conctor joint or leakage, poor winding insulation, etc., the current will be weakened, and the electromagnetic torque generated by this phase current passing through the stator winding will also be reced, so it is difficult for the mill to start and the motor will be overloaded
elimination method: disconnect the motor from the gearbox, start the motor under no load, check the current of each phase with a clamp ammeter, and check the winding of the motor when the current is abnormal, such as checking the insulation with a megger, find out the cause, and then start the motor after treatment
there are ore or steel balls in the feeding box. For closed-circuit grinding, if the ore and steel balls from the bulging belly of the grinding machine are not removed from the feeding box, or after the grinding is stopped, the classifier is not stopped in time, so that the returned sand can be accumulated in the feeding box. When the mill is started, the feeding scoop is blocked, resulting in a large eccentric torque, which causes the motor overload
Troubleshooting: open the treatment hole at the bottom of the feeder box and clean up the ore and steel balls
there is slurry leakage from the connecting bolt of cylinder liner plate
causes: the nut fixing the liner plate is loose, the sealing gasket is damaged, the screw is broken, the liner plate is broken or falls off, etc
Troubleshooting: tighten or replace the bolts, add sealing washer, and replace the liner if necessary
the sound inside the grinding machine is weakened or enhanced
the main reason for the weakening of the sound inside the grinding machine is that the feeding amount is too much, the block is too large, the feeding amount is greater than the discharge amount, and the grinding machine begins to swell
the exclusion method was treated as the exclusion method
the increased sound in the mill may be e to too little feeding, resulting in empty grinding, and the medium directly strikes the liner or the medium strikes each other. When the feeding is normal and the sudden sound intensifies, it is caused by the lining plate or grid plate falling off
elimination method: increase the feeding amount. If the liner falls off, stop the machine immediately to replace or reassemble the liner
the grinding machine suddenly proces strong vibration and impact sound. One of the following reasons will cause the above phenomenon:
iron impurities are mixed in the gear clearance. The elimination method: stop the machine immediately and trim the tooth surface
the pinions move in series in the axial direction and collide with the gearbox. The elimination method: stop immediately, replace the gearbox and fix the gears along the axial direction again
if the gear is damaged, the elimination method is to stop immediately and replace the gear
if the bearing or anchor bolt is loose, the elimination method: first adjust the gear to make the big and small gears mesh correctly, and then tighten the bolt.

4. Now bitcoin is out of business. The risk is high
5. It's normal for you
1) ant S3 miner, I saw several comments from friends in the Forum
the official power consumption is 332w, and businesses usually report 355w
the actual power consumption is about 390W
2) your power supply is rated at 500W, which is basically 400W after decting the conversion loss
theoretically, it should be able to drive,
however, for the consideration of long-term stability, the miner generally requires higher power supply when designing
the fault tolerance between 390W and 400W is less
therefore, we all use 600W rated power supply in the forum and online evaluation
(Rated 600, not the highest 600)
the stability of mining machine is very important. A stable and suitable power supply will definitely save you a lot of trouble in the future
some suggestions for your reference

according to P = FV, 6KVA generator, the output current is only 24a, a 7.5kW water pump and 5.5kW mining machine, the total power is 13kw, the normal current has 26a, overload. Moreover, the starting current of the motor is larger, that is, the starting current of 7.5kW is about 30A. If the 7.5kW is started first, the working current is already 15a, and then the 5.5kW is started, the starting current is 20a, and the total current is 35A
-
it's mainly about the selection of contactors. It's better to use contactors with larger capacity, because the water pump motor starts with load, and the current at the moment of starting is too large, which will cause great damage to the contacts of contactors. If the selection is small, it will affect the service life of contactors
The output voltage of the generator should be increased correspondingly ring the motor starting process to protect the voltage drop ring the motor starting. There should be no problem with 3KW motor with 1.5KW. It is enough to adjust the speed of the generator ring the start-up< br />
