Power Protector also known as lightning protection device, surge protector or arrester, Power Protector is the role of the line on the surge voltage (instantaneous overvoltage/inrush current) guidance to the grounding device, release to the Earth, so as to achieve the purpose of protection equipment.
Power Protector uses relays, resistors, integrated LM324 and other electrical components produced, Power Surge Protector when the circuit appears over the rated voltage or current value, Power Surge Protector the protector can quickly cut off the power supply, to avoid the burning of household appliances
Power Protector Product Features
1. High brightness luminous tube instruction.
2. Easy installation and long service life.
3. Beautiful appearance, good security.
4. When the voltage is lower than 170V or higher than 260V, the relay Rapid action disconnect when the voltage return to normal, the switch delay of 3 minutes automatically closed, Power Surge Protector effective to protect the role of home appliances.
5. Multi-channel output power plug. or terminal terminals
How the Power Protector works: The Power protector is generally in high impedance state, when the line surge current, the power protector in a very short period of time (nanosecond) conduction and ground connection, because the grounding system has a low grounding resistance, most of the surge current through the surge protector to release the Earth, The power line passes through the discharge effect of multistage surge protector, Power Surge Protector which eventually reduces the inrush current to the state that the equipment can withstand. Other types of surge protectors are designed to achieve surge protection by disconnecting from subsequent lines.
The main factors that cause surge voltage (surge current or surge) in low voltage power supply system, measurement and control system, computer network system, Power Surge Protector monitor and so on are as follows:
1. Direct Strike Thunder
Lightning strikes the building directly, and the energy of the lightning around 50% will be diverted through power lines, Power Surge Protector signal lines and other metal pipes and cables in the building. The proportion of energy allocated here varies with the wiring and pipeline structure within the building.
2. Conductive Ray
Lightning may be directly to the power line (Low-voltage overhead line) or data signal line discharge, the majority of high-energy lightning current along the wire is introduced into the building.
3. Nearby lightning strike
Nearby lightning blitz may also cause surge voltages (surge currents) on building installations. The surge voltage is directly or electrically coupled through the electromagnetic or capacitive coupling to the circuit of an electronic device or device. For example between the Lightning discharge channel (lead line) and the metal wire.
4. Lightning strike in the distance
is hundreds of meters away from the Lightning blitz may be in the low-voltage wire, data line on the induction of over-voltage, but also the high voltage may be transmitted to the building grounding device, Power Surge Protector thus causing great harm to electronic equipment. Even the electromagnetic fields generated by discharges between clouds or inside the clouds can also be coupled with surge voltages to wires.
5. Switch surge
Switching surges from the circuit closed, disconnected and other conversion operations, Power Surge Protector from the perceptual and capacitive load switch operation, but also from short-circuit current interruption. In particular, the disconnection of large power systems or transformers may cause damage to adjacent electronic devices.
