Product details:
1.Product Overview
Surge Protective Device (SPD) is an electrical protection device used to protect electrical equipment from voltage surges. Surge voltage is usually caused by lightning, switchgear operation, or other fluctuations in power lines, which can cause serious damage to sensitive equipment. SPD ensures the safe operation of power systems and connected equipment by absorbing or limiting overvoltage, and is an indispensable part of modern electrical systems, especially widely used in industrial, commercial, and household power systems.
2.Main features
Efficient surge protection:
SPD can effectively suppress surge voltage caused by lightning strikes, switch operations, or power equipment failures. It limits the voltage within a safe range by absorbing or dispersing excessive current, avoiding damage to electrical equipment.
Fast response time:
SPD design has ultra fast response time. When surge voltage occurs, it can quickly start and restore the voltage to a safe level, minimizing the risk of damage to electrical equipment.
Multi level protection:
Most modern SPDs adopt a multi-level protection mechanism, including a pre protection stage, a filtering stage, and a voltage limiting stage, to ensure that the equipment is fully protected throughout the entire surge process.
Strong compatibility:
SPD is suitable for various electrical systems, compatible with different types of power systems such as low voltage, industrial, and high voltage, and protects various types of electrical equipment, such as household appliances, computer equipment, communication equipment, etc.
Long term durability:
SPD uses high-quality protective components such as gas discharge tubes (GDT), varistors (MOV), and diodes, which have a long service life. They can withstand multiple surges without damaging the equipment itself.
Easy installation:
There are various installation methods for SPDs, which can be directly connected to the power distribution system for centralized installation or independent protection of specific equipment. It supports quick access and replacement, making it easy to maintain.
3.Application scenarios
Industrial sector:
In industrial production, large electrical equipment such as motors, control systems, transformers, etc. are often exposed to the risk of power surges. SPD can provide necessary protection for these devices to avoid faults or damage caused by surge voltage, ensuring the stable operation of the production line.
Home electrical system:
Household electrical equipment, especially high-value household appliances such as televisions, air conditioners, computers, and audio equipment, may be threatened by surge voltage. After installing SPD, it can effectively extend the service life of household appliances and reduce the economic losses caused by electrical failures.
Communication and Data Center:
In communication systems or data centers, sensitive devices such as servers, routers, and switches are extremely sensitive to voltage surges. By installing SPDs near the power input or equipment, these high-value devices can be protected from voltage fluctuations and lightning strikes, ensuring the secure transmission of data.
Commercial buildings:
Various electrical facilities in commercial buildings, including air conditioning systems, elevators, lighting systems, etc., also need to prevent interference from voltage surges. The installation of SPD can effectively avoid equipment failures caused by power issues, reduce maintenance costs, and minimize the occurrence of emergencies.
New energy system:
SPD protection is crucial for new energy systems such as solar and wind power. The inverters and battery storage devices of these systems are susceptible to power fluctuations and lightning strikes, and the use of SPDs can significantly improve the stability and reliability of the systems.
4.Technical specifications
Rated voltage: SPDs are typically designed to adapt to low voltage (AC 220V, 380V) and high voltage (AC 10kV) power systems, ensuring that they meet the needs of different application scenarios.
Response time: Most SPDs have a response time of nanoseconds, which can quickly respond and limit overvoltage at the moment of voltage surge.
Protection types: Common protection types include overvoltage protection, overcurrent protection, and short-circuit protection, which comprehensively ensure the safety of electrical equipment.
Energy absorption capacity: The energy absorption capacity of SPDs is usually measured in kA or J (joules), and the appropriate model of the equipment needs to be selected based on the magnitude of the surge current.
Working temperature: The working temperature range of SPD is usually -40 ° C to+85 ° C, suitable for different environmental conditions.
Voltage resistance level: The maximum withstand voltage capability of SPD is usually several thousand volts, which can cope with high voltage surges from lightning or grid fluctuations.
5.Product advantages
