◆ External power failure maintenance power indicator lamp: 4-way standard configuration, capable of normal maintenance of circuit breakers, contactors, oil switches, cables, lines and other equipment;
Power supply system: The auxiliary power supply is an isolated power supply (SPS), ensuring the output voltage and current of the auxiliary power supply;
The design principle of the Y-disk type two control and three control scheme is to adjust the output voltage and current of the power battery to an appropriate level;
When designing the power supply of equipment, people must set rated load switches on any power transformer, power sensor, controller, filter, power amplifier device, output power amplifier, and all parts that should be considered. The connection resistance of each part of the load should be less than 05 Ω, and the possibility of connecting to a "power failure node" should be reduced to 10 Ω. Switches for heat sinks and power lines must be used, such as cutting off common ground and winding loads, and wiring must also be modified.
The output working voltage of a switching power supply should be equal to the power product of the power system. Usually, switching power supplies have high power and discontinuous operation, and sometimes it is necessary to mention safe geothermal energy. Although switching power supplies have low power, the power system is a state that the system does not frequently enter during operation, and a higher working voltage can also be set as needed. The power capacity is generally, but the efficiency is low, so a lower working voltage should be set according to actual needs to ultimately achieve the efficiency of the power system. Due to its small power factor, it is necessary to choose a high-voltage switching power supply with higher power. If a certain circuit does not require stability, the efficiency of the power supply will be low, sometimes with relatively small burrs and high working voltage. In order to more effectively regulate the load, about one maintenance installation is required. Therefore, the total load power consumption of the circuit is very high, and the power is much higher than that of the high-voltage switching power supply. For switching power supplies, their total output load power consumption is much higher than that of high-voltage switching power supplies, and high-voltage switching power supplies are the primary indicator. When the power of the switching power supply is less than 10W, the efficiency of the switching power supply will be higher, which can lead to defects in the main circuit components of the power supply, such as poor contact at the conduction point, shutdown, etc. For this reason, the maintenance of switching power supplies requires engineers to have three responsibilities: designing the power structure while executing the master-slave ratio. All of these require an engineer's enthusiasm for work and there must be no significant demand for the functionality and performance of the device. The following are some explanations of power circuit, power maintenance skills, and work.


For purposes such as power maintenance, power testing, and troubleshooting (such as power on, power on, abnormal noise, etc.), and with the ability to optimize and adjust the power supply and regulator circuits,
Check the stability of the power load, the current of the load should not exceed 1A, and select a fake load. If there are sparks between the real and fake loads, the load can be completely removed.
When checking the capacitor, a certain angle of load should be injected into the capacitor. The capacity of the capacitor can be selected to be smaller, usually 2. 3PF, the slower the allowable capacitance current change, the greater the relative current, and the impact on the capacitance lifespan.
Capacitor, the capacitor you use is a bit larger, and when it comes to the lifespan of your capacitor, which is the shortest lifespan, the increase in capacitor lifespan is the capacitance of the capacitor, which allows for an increase in capacitance. Therefore, the lifespan of the capacitor must be increased, and the lifespan should be minimized as much as possible. The increase in capacitance also has an impact on the performance of the capacitor.
