Lightning arrester 1. Lightning arresters have multiple voltage levels, ranging from 0.38KV low voltage to 500KV ultra-high voltage, while surge protectors generally only have low-voltage products; 2.
3.1 Installation location According to the concept of IEC131221 (LPZ), when the electrical line passes through the junction of two lightning protection zones, a surge protector should be installed. Ac
Surge Protector Parameter Selection 2.1 Protection mode SPD can be connected between L (phase line), N (neutral line), and PE (protective line), such as L 2L, L 2N, L 2PE, and N 2PE. These connection
Surge Protector Protection Classification According to the characteristics of the nonlinear elements used 1.1 Voltage switching SPD Common nonlinear elements include discharge gaps, gas discharge tube
Surge Protector Performance Characteristics 1. Large protection flow, extremely low residual pressure, fast response time 2. Adopt the latest arc extinguishing technology to completely avoid fire; 3.
222222 is divided into two types: explosion-proof box type and module type. Both use a varistor with excellent nonlinear characteristics. Under normal circumstances, the surge protector is in an extre
Surge protectors are usually connected in parallel to the circuit system. When lightning occurs, high-intensity electromagnetic induction is generated on various metal pipes and wires entering the bui
Surge protectors are suitable for TT, TN-S, TN-C, IT and other power supply systems with AC 50/60Hz and rated working voltage of 220V/380V, as well as factory low-voltage power and control systems. Th
Power surge protector, also known as power lightning arrester, is suitable for AC 50/60HZ, rated voltage 220V/380V power supply system, to protect against indirect lightning and direct lightning effec
Surge Protectors (SPDs) are specifically designed to protect sensitive equipment from damage caused by lightning strikes and transient surges. Surge Protectors (SPDs) integrate discrete protection dev
Surge protection is necessary: Surge protection in low-voltage systems is becoming increasingly important due to the increasing number of losses. Direct lightning strikes can not only cause losses d
Surge Protector Product Features 1. Single-pole L/N-PE; 2. In = 10kA; 3. Imax = 20kA; 4. High-energy MOV; 5. Modular design
(2) UPS protection. Install a V20-C module between each phase line and the neutral line, install an air switch in front of each module, and install a V20-C/NPE module between the N line and the ground
According to the provisions of GB50057-94 (2000 edition) of the Lightning Protection Design Code for Buildings, buildings in the LPZ0B, LPZ1, and LPZn+1 lightning protection zones should take measures
According to their use, Surge Protectors can be divided into two types: power line SPDs and signal line SPDs. (1) Power line SPD Since the energy of lightning strikes is very huge, it is necessary to
According to their working principles, Surge Protectors can be divided into voltage switching type, voltage limiting type and combination type. (2) Voltage limiting type SPD. When there is no transien
The type and construction of surge protectors vary depending on the application, but they contain at least a non-linear voltage limiting element. Commonly used surge protectors include MOV (Metal Oxid
Surge Protectors Since different countries follow different standards, product specifications are not unified, and parameter markings also have their own emphasis, which is far less than other electri
A represents a surge protector consisting of four varistor modules, suitable for TN-S system, representative models AM40A, AM80A, etc.; B represents a surge protector consisting of three varistor modu
In order to facilitate customer selection and better protect equipment, we launched the B+D composite surge protector, which has large current capacity and low residual pressure level. The same model
When you need to remotely monitor the degradation status of the surge protector, you can choose a product with an alarm. With an alarm, the surge protector can be equipped with a remote signal alarm t
The value of Up is similar to the residual voltage value of the surge protector (but Up is not the residual voltage). When the surge protector is activated, a part of the residual voltage will be load
Scope of application: This product is used in conjunction with a surge protector and is connected in series to the front-end line of the surge protector as a backup protection switch for the surge pro
1. Definition of flow rate parameters: Impact current Iimp: The test waveform is 10/350μs, which is a T1 test. The first-level surge protector must have this parameter. The test values are usually:
