Aging load test of miner switch power supply

mining
Mining times: recover a little every two minutes. Every time you dig a grid, you will spend a mining time
reset the mining area back to the original state: the manual refresh device of the mining area is updated every two days
it only takes a few seconds to dig the soil, and it takes a little time to dig. It takes a lot of time, ranging from 20 minutes to 2 hours, to dig all kinds of gems, diamonds and Titans
the detonator can clear the time immediately, but the bigger the detonator is, 5-6 pieces of different kinds of ores can be obtained with each broken purple gold rock
hoe level: will be improved with the map opening event
ore type: ordinary ore (copper, tin, iron, silver, gold), various gems, diamonds, troll statues, and various soul crystals
ore usage: it can be used to forge equipment and open backpacks
detonator: clear the mining time immediately It's mainly used to dig zijinyan. There's no way to dig zijinyan. It can only be blasted with detonators.)

4. The current withstand value of the fuse exceeds the rated current value and burns out

there is a short circuit in the circuit, resulting in short-circuit current, and the fuse will be blown if the short-circuit current is too large

if there are too many electrical appliances, the fuse will burn, just like the leakage protection switch, if the power is too large, the load will trip

the reasons for frequent fuse blowing are as follows:

check whether the circuit at the back end of the power supply [fuse] is short circuited

check whether the electrical equipment on the line at the back end of the power supply [fuse] is short circuited

check whether the load at the back end of the power supply [fuse] used is too large, and whether the capacity of the fuse is 2-2.5 times of the overload current

check whether the set of power supply [fuse] is tightly installed to avoid poor contact

check whether these fuses are proced by regular factories and meet the standards.

5. If you want to use the switching power supply of the computer for other purposes, you can change it as follows:
1. Open the iron box of the power supply, take out the circuit board from the box, and use a brush to remove the st
2. Find the key components. Including: power oscillation integrated block, optocoupler, 12V voltage regulator, pulse width adjusting potentiometer, etc. Find the information of power supply mole
3. First, change the 12V voltage regulator into 15V, and find the pulse width adjustment circuit according to the data of power supply integrated block. Some power supplies do not design power supply fine-tuning, but fixed resistance. Remove the fixed resistance, and connect a potentiometer whose resistance value is basically close to the welding resistance on the two solder joints. Now adjust the resistance of the potentiometer to the maximum
4. Use a multimeter to monitor the 12 V power supply port, turn on the power supply, slowly rece the resistance of the potentiometer, observe the voltage change, and adjust it to 15 v. After stabilization, observe for a little time and connect the false load toaster
5. After it is accurate, measure the resistance of the potentiometer and replace it with a fixed resistance with the same resistance.
