Description
Technical field
The present invention relates to protection technical field of electric equipment, especially a kind of Novel hot for overvoltage protection plugs not electricity cut-off type surge protector.
Background technology
Traditional surge protector is called the title such as Surge Protector, lightning protection grid.Its main effect is all for the protection of class signal detection and control equipment, prevents by external disturbance such as the electrical surge be struck by lightning or high-voltage switch gear causes, transient voltages.In the surge impact of a relative brevity, by ground of being released to by transient current, by the voltage clamping between holding wire a lsafety level, and guarantee the signal normal transmission on holding wire, for industrial automation equipment escorts safely.Its inside at least comprises non-linear element composition, and before transient state surge future, this element will present high resistance, does not affect protected circuit; And during transient state surge arrival, this element changes rapidly low resistance into, is released by surge current, and the voltage at protected equipment two ends is limited in lower level.When terminating to surge, this non-linear element again self-recoverage is high-impedance state.Be widely used in the protection of the systems such as process industry, oil-gas exploration and exploitation, draining and sewage disposal technology, energy technology, traffic technique and building automatic at present.
At present, the surge protector of class signal equipment protection is commercially known, the structure of integral type that more traditional is.In recent years; also there is the surge protector structure of plug type; two parts are made by connection terminal module and overcurrent/over-voltage protection module; can carry out fast installing and changeing; but when changing product protection module; the signal transient that transmission channel occurs is interrupted, and often bring very large broken string blind spot to real-time monitoring system, the existence of the unreliable phenomenon of swapping process causes very large loss to high accuracy real-time monitoring system.But traditional all-in-one-piece Surge Protector structure, when damage of product is changed, not only to dismantle all wiring, also need to carry out complete machine dismounting, and then more renew surge protector and get on, and do wiring work again.This kind of integral type surge protector dismounting is complicated, increases quantities, and when changing complete machine surge protector, virtually increases cost.In the control cubicle installing level of confidentiality, traditional Integral electric surge protector and plug type surge protector lack label dust cap and industrial item mark, distinguish bring huge trouble to instrument protection and physical cabling installation.
As Chinese invention patent " the continual Surge Protector of plug protection module signal "; application number is 201320354122.1; disclose the unbroken Surge Protector of a kind of signal; when Surge Protector damage needs to change; the binding post base having connected intact wire can be pulled down, only need to change the superincumbent hot plug module of plug-in mounting.But hot plug module complex structure at present, do not have instrument protective cover and industrial item etc. clearly, the contact safety of this product plug-in module is not high.If module coming in contact when plugging loosening, when interior contact is bad, the forfeiture of the uninterrupted function of surge protector plug-in module signal can be caused, in a disguised form lose the performance of product itself.
