The difference between DC and AC power surge arresters
The power surge protectors are mainly divided into two types: DC power surge protectors and AC power surge arresters:
1. DC power surge protectors are used to prevent damage caused by lightning overvoltages and transient overvoltages to DC power systems and electrical equipment. Applicable to various DC power supply systems, DC power distribution screens, DC power supply equipment, DC distribution boxes, electronic information system cabinets, secondary power supply equipment output.
2. The AC power surge protector is suitable for damage to the equipment caused by terminal equipment power distribution, lightning overvoltage and transient overvoltage; in the power system, it is mainly used in the automation equipment room, the main control room of the transformer substation, and the power supply screen three-phase power input. Or output.
What is the difference between the characteristics of the DC power supply lightning protection device and the AC power supply lightning protection device?
DC lightning arrester features:
1.Using temperature control circuit breaker technology and built-in over-current protection circuit to completely avoid fire risk
2. Work status and failure status, clear and intuitive
3. Easy to install and maintain
4. Exquisite workmanship, long-term work in harsh environments such as acid, alkali, dust, salt fog, and humidity
AC power surge arrester features:
1. Low residual pressure and fast response time;
2.Using temperature control protection circuit, built-in thermal protection, stable and reliable work;
3. Reasonable design and easy installation.
4. Low loss and long service life.
