Take you to understand the operation and maintenance of DC power supply system

Release date：2022-01-10

DC power supply equipment is the power plant of the power system and some substations are very important control, power supply and signal. DC power supply system plays a very important role in the operation of the equipment.

There is also with the continuous development of power technology, the continuous improvement of substation automation, there are a lot of important data to be safe and reliable preservation and processing, a variety of electrical equipment, such as relay protection, carrier communication, accident lighting work are inseparable from the DC power supply. When some problems occur in the system, in the case of power failure, we will use the DC power supply system. If there is no such system, then it is impossible to provide reliable DC power supply provided by working equipment, which will cause great losses. Therefore, some people compare the DC power supply system to the heart of substations and power stations.

Inspection of DC cabinet

It is to check the meter needle and signal lamp of the DC charging cabinet to see if there is any abnormality. If there is any abnormality, it should be repaired in time.

Check whether the condition of each switch of the control of the equipment is normal,

Inspection of DC Battery

Spot check or check and test the battery voltage and specific gravity one by one. Test whether the discharge performance of the battery is intact.

Inspection of DC power supply battery

Check and measure is the temperature inside, do a good job of the corresponding ventilation facilities.

Check whether the indoor lighting and other attached equipment are in good condition, and problems should be solved in time.

Inspection of DC Power Charging Equipment

Check whether the DC panel module and the rectifier transformer are running normally and whether it is too hot. If there is such a phenomenon, replace it immediately.

Principle and precautions of programmable DC power supply

Programmable DC power supply has two programming methods, one is active, the other is passive. The passive programming algorithm is to change the reaction resistance and the input resistance to change the output value. The active programming algorithm is to change the output value of the reference voltage and the current of the reference. Secondly, there is the programming speed of the power supply.

Take you through the seven important components of DC power

Rectifier module system: The power rectifier module is the module that converts alternating current into direct current, usually according to the size of the current. It can be used in parallel with multiple modules. The module itself has perfect protection functions, such as input overvoltage protection, output overvoltage protection, output current limiting protection and output short circuit protection.

Waveform characteristics of DC regulated power supply

In the DC voltage regulator circuit, the waveform of the output voltage is mainly manifested in two aspects: ripple and noise. Ripple refers to the periodic fluctuation of the output voltage, which is caused by the AC component of the power supply current. In the circuit, the magnitude of the ripple is related to the capacitance value of the capacitor filter and the load current. The smaller the capacitance value, the greater the load current and the greater the ripple. Noise refers to the output voltage of high-frequency random fluctuations, usually by the components of their own noise and power supply current in the high-frequency components caused. In the DC voltage regulator circuit, the size of the noise is related to the phase noise of the components and the quality of the power supply current.
