Surge protectors (surge protectors), also known as surge protectors, are abbreviated as (SPD) for use in AC 50/60HZ, rated voltage 220V to 380V supply systems (or communication systems), and for indirect lightning and direct lightning effects or Surge protection with other transient overvoltages is suitable for surge protection requirements in the family home, tertiary industry, and industrial sectors. It has a relative, relative, relative neutral, neutral to earth, and combinations of protection models.
Basic Features:
1. Large flow of protection, low residual pressure, fast response time;
2. Use the latest arc extinguishing technology to completely avoid fires;
3.Using temperature control protection circuit, built-in thermal protection;
4. With a power status indicator to indicate the working status of the surge protector;
5. The structure is rigorous and the work is stable and reliable.
Installation method :
Surge protector with 35MM standard rail mounting
For a fixed surge protector, the general installation should follow the steps below:
1) Determine the discharge current path
2) Wires marking the extra voltage drop caused by the device terminals.
3) To avoid unnecessary induction loops, the PE conductor of each device should be marked
4) Establish equipotential bonding between the equipment and the surge protector.
5) To carry out energy coordination of multi-stage surge protectors
In order to limit the inductive coupling between the protected portion after installation and the unprotected device portion, certain measurements are required. Separation of the sensing source and the sacrificial circuit, the choice of the loop angle, and the restriction of the closed loop area can reduce mutual inductance.
When the current-carrying component wire is part of a closed loop, the loop and induced voltage are reduced due to the proximity of the wire to the circuit.
In general, it is better to separate the protected conductor from the unprotected conductor, and it should be separated from the grounding conductor. At the same time, in order to avoid transient orthogonal coupling between the power cable and the communication cable, necessary measurements should be made.
