Description
Technical field
The utility model relates to a kind of intelligent protection module of Surge Protector, belongs to the surge guard technology field of electronic electric equipment.
Background technology
The line surge that the line surge of thunder and lightning and initiation thereof and other reason cause is to cause the major reason that electric/electronic device is aging and damage.The installation Surge Protector is one of important measures of lightning protection on the metallic circuits such as the power line of electronic equipment, holding wire and control line being connected in.In this technical field, a major issue that exists is at present: Surge Protector is in protection equipment, deterioration can take place gradually until thorough damage in the device of himself, or directly damages under excessive surge impact, or proximity switch type surge protective device produces afterflow; For power source surge protector, its damage or the phenomenon that causes damage have short circuit (comprise afterflow, below omit) and leakage current increase to cause to generate heat two kinds; For the signal Surge Protector, the phenomenon of its damage is generally Surge Protector to two kinds of the impedance increasing of signal transmission and surge protective device short circuits.Which kind of situation no matter occurs, all must in time surge protective device be spun off from circuit, otherwise phenomenons such as burning, switch trip power failure, signal transmission fault will occur.
Addressing the above problem existing technical method at present is: serial connection is protected in support on the Surge Protector loop circuit breaker or fuse; when expectation short circuit occurs at surge protective device; circuit breaker or fuse tripping or fusing, thus surge protective device is spun off from circuit.
Still there are the following problems for above-mentioned solution: the selection of circuit breaker or fuse parameter, conflict with the requirement existence of power distribution protection, and can not satisfy the requirement of the selectivity cooperation of power distribution protection.For signal circuit, voltage is low, electric current is very little, requires fuse to disconnect when the surge protective device short circuit, can not disconnect when powerful surge impact, does not still have the product (fuse or circuit breaker) that meets this requirement at present.
Change an angle in fact and say, to the circuit breaker of the above-mentioned use of connecting with surge protective device or the ideal requirement of fuse be: will disconnect at once even very little power current or signal code flow through also, very large surge current then can not disconnect.Obviously, owing to there is not better technical scheme, generally adopting fuse or circuit breaker in the industry of surge protection at present is caving-in bash as the short-circuit protection of Surge Protector.
The utility model content
In order effectively to overcome the above problems, the utility model proposes a kind of intelligent protection module of Surge Protector.
The purpose of this utility model provides a kind of intelligent protection module of Surge Protector; can the physical quantity of surge protective device be detected; analysis and judgement surge protective device whether short circuit or deterioration damages, thereby is short-circuited or deterioration in time spins off it from circuit when damaging at surge protective device.
The utility model is realized by the following technical solutions: the intelligent protection module of Surge Protector is made of measurement and control unit (1) and backup protection unit (2).
Measurement and control unit (1) is connected by lead with backup protection unit (2) and is loaded in the same housing (3).Measurement and control unit (1) is provided with circuit such as signals collecting, processing, control, communication; signal acquisition circuit is connected with the detecting unit of Surge Protector by detection terminal; to gather the real time information of Surge Protector; control circuit is connected with the control loop of backup protection unit (2); telecommunication circuit is connected to the communication terminal (7) of this module, realizes telecommunication.Backup protection unit (2) is provided with control loop and protection loop; control loop is connected to measurement and control unit (1); the protection loop is connected in series with Surge Protector to the surge protection loop, and when the Surge Protector short circuit, backup protection unit (2) action in time breaks away from Surge Protector from circuit.Measurement and control unit (1) can be connected with one or more backup protection units (2), is loaded on jointly in the same housing (3), also can be combined into a product by being loaded in the different housings.
Advantage of the present utility model is: adopt measurement and control unit (1) and backup protection unit (2) integrated; possessed collection, processing, the control of Surge Protector information, the function of communication simultaneously; and measurement and control unit (1) can be set according to the characterisitic parameter of Surge Protector and protected circuit; make backup protection unit (2) controllable action, efficiently solve above-mentioned existing problems.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an embodiment of the present utility model, is the intelligent protection module of the Surge Protector of a measurement and control unit and four backup protection unit compositions.
Among the figure: 1, measurement and control unit, 2, backup protection unit, 3, housing, 4, surge loop input terminal, 5, surge loop lead-out terminal, 6, detection terminal, 7, communication terminal, 8, power supply terminal.
Embodiment
The concrete scheme of embodiment is as follows:
As shown in Figure 1, the utility model adopts following measure to realize: adopt the lead connection respectively between measurement and control unit (1) and four the identical backup protection units (2), be loaded on jointly in the same housing (3).The surge loop input terminal (4) of backup protection unit (2) connects the surge protection loop, and surge loop lead-out terminal (5) is connected with Surge Protector, and backup protection unit (2) and Surge Protector are connected in the surge protection loop.Measurement and control unit (1) is connected to the detection lead-out terminal of Surge Protector by detection terminal (6); to gather the real time information of Surge Protector; measurement and control unit (1) communicates by communication terminal (7) and remote terminal network; various information are transmitted, and power supply terminal (8) is connected to the power supply that external power source is realized measurement and control unit (1).In the concrete work: the protection loop of backup protection unit (2) and Surge Protector series connection are in the line; when the Surge Protector short circuit; measurement and control unit (1) detects the parameter of Surge Protector; after handling by analysis; the output control signal is given the control loop in the backup protection unit (2); control loop control backup protection unit (2) protection loop disconnects, and to cut off the surge protection loop, Surge Protector is spun off from circuit.
