Description

A kind of Modular electrical surge protector

Technical field

This utility model relates to a kind of Modular electrical surge protector, belongs to protection electrical equipment technology neck Territory.

Background technology

Traditional surge protector is referred to as the title such as Surge Protector, lightning protection grid.Its main effect is all to use In protection class signal detection and control equipment, prevent electrical surge, the transient state caused by thunderbolt or high-voltage switch gear The external disturbance such as voltage.In the surge impact of a relative brevity, by transient current being released to ground, By the voltage clamp between holding wire a level of security, and guarantee the signal normal transmission on holding wire, Escort safely for industrial automation equipment.It is internal including at least a non-linear element composition, transient state Before surge future, this element presents high resistance, does not affect by protection circuit；And transient state surge During arrival, this element is changed into rapidly low resistance, is released by surge current, by by protection equipment two ends Voltage is limited in relatively low level.When terminating to surge, this non-linear element self-recoverage again is high-impedance state. Be now widely used in process industry, oil-gas exploration and exploitation, draining and sewage disposal technology, energy technology, The protection of the system such as traffic technique and building automatic.

At present, the surge protector of class signal equipment protection is commercially it is well known that the most traditional is one The structure of formula.In recent years, also occur in that the surge protector structure of plug type, will wiring ground terminal Make two parts with overcurrent/over-voltage protection module, can be rapidly performed by installing and changeing, but more When changing product protection module, occur the signal transient of transmission channel to interrupt, often bring to real-time monitoring system The biggest broken string blind spot, high accuracy real-time monitoring system is caused the biggest damage by the existence of the unreliable phenomenon of swapping process Lose.But traditional all-in-one-piece Surge Protector structure, when damage of product is changed, institute to be dismantled There is wiring, also need to carry out complete machine dismounting, the most more renew surge protector up, and do wiring work again Make.This kind of integral type surge protector dismounting complexity, increases quantities, and changes complete machine surge protector Time, virtually increase cost.Traditional Integral electric surge protector and can inserting in the switch board installing level of confidentiality Pull out formula surge protector and lack label dust cap and industry item mark, instrument protection and physical cabling are installed Distinguish and bring huge trouble.

Such as Chinese utility model patent " the plug protection continual Surge Protector of module by signal ", Application No. 201320354122.1, disclose a kind of unbroken Surge Protector of signal, damaging at Surge Protector needs Time to be changed, the binding post base having connected intact wire can be pulled down, it is only necessary to change and be inserted into The hot plug module in face.But at present hot plug module structure is complicated, the most clearly instrument protective cover and Industry items etc., the contact safety of this product plug-in module is the highest.If module connects when plug Touch and loosen, when interior contact is bad, the forfeiture of the surge protector uninterrupted function of plug-in module signal can be caused, In a disguised form lose the performance of product itself.
