315A Back Up Fuse Lightning Arrester Surge Protector for Elevator Installation

Product Specification

 Lightning Arrester / Power Surge Protection Device for Elevator Installation

 
 
According to the standard elevator power distribution cabinet, it is necessary to install a surge protector, and the elevator is responsible for carrying people and objects, which is very important, and the lightning protection of the elevator power distribution system should be paid more attention.
 
In the lightning protection of the building power distribution system, the elevator machine room belongs to the three-level lightning protection or the last-level lightning protection (the main power distribution level one, the floor distribution level two, and the elevator machine room three level).
Since the surge protector is installed to protect the equipment of the elevator motor controller, the residual voltage or protection level of the surge protector in the elevator cannot be high. When the residual voltage is high, the lightning protector will also play a role, but the elevator Still beaten by thunder.
 
According to the standard elevator lightning surge protector, products with protection level Up: 1.2KV should be selected (the residual voltage value will be slightly lower than the protection level), and the protection level of the elevator surge protector will also be paid attention to in the lightning protection acceptance of the Meteorological Bureau , Which is the Up value.
Therefore, the elevator selection lightning protection device must pay attention to this point.
OBV10-I-15
Surge protectors OBV10-I-15 meet the type 1 requirement class according to IEC 61643-11. These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions.The voltage-limiting,high-performance spark gaps provide several benefits.A short response time, a low protection level and high current leakage capability with long service life.

Transient voltage surgesin lv power lines
Transient overvoltages are voltage surges that can reach tens ofkilovolts with a duration of the order of microseconds.Despite theirshort duration, the high energy content can cause serious problemsto equipment connected to the line, from premature aging to destruction, causing disruptions to service and financial loss.Thistype of surge can have various different causes, including atmospheric lightning directly striking the external protection(lightning rods) on a building or transmission line or the associatedinduction of electromagnetic fields on metallic conductors.
Outdoor and longer lines are the most exposed to these fields,which often receive high levels of induction.
It is also common for non-weather phenomena, such as transformer centre switching or the disconnection of motors orother inductive loads to cause voltage spikes in adjacent lines.
 

 
Importance of theground connection
Overvoltage protectors (SPD) divert excess energy toground, so limiting the peak voltage to an acceptablevalue for connected electrical equipment.
A ground connection in adequate condition is, therefore,a key aspect for effective protection against overvoltages.Monitoring ground connection condition guaranteesproper operation of surge protection devices.
